Hey guys, it's

Nurse Mike here from SimpleNursing .com.

Today we're breaking down the types of shock that you need to know for your nursing exams, from hypovolemic to cardiogenic and more.

We'll make it super simple, memorable, and easy to stick.

Plus, if you're a Simple Nursing member, be sure to grab your shock study guides to follow along.

Trust me, this is high -yield, top -tested stuff.

So, let's get started.

shock is a critical condition where the body has decreased tissue perfusion eventually leading to organ failure

and death the classic sign to know for your exams

and the enclex is low blood pressure

so the memory trick just think of the double s's s for shock we see severely low blood pressure

and so oxygen can't get to the organs leading to organ failure

and death now for the four stages of shock first is the initial stage

there's too little oxygen in the blood to feed the organs resulting in anaerobic metabolism meaning metabolism without oxygen

but the signs

and symptoms are absent in this stage now the second is compensatory stage

this is where the body is trying to compensate for

that low oxygen so the heart will pump faster going into tachycardia the respiratory rate will increase to get more oxygen,

so we see tachypenia, and the body compensates with the sympathetic nervous system to speed up the vital signs,

and the renin -angiotensin activation to maintain blood pressure and oxygenation to keep the organs perfused.

Now, as compensatory mechanisms fail, clients progress into the progressive stage.

Now, a key sign to know for your exams is cold and clammy skin.

This is priority.

Huge NCLEX tip.

So write that down.

This is an early sign that the body is lacking perfusion and getting worse.

Not being able to compensate anymore.

It's progressing into this progressive stage here.

So don't let the NCLEX trick you.

It's not low oxygen saturation and it's not tachycardia.

Those are compensatory as the body is trying to scramble for oxygen.

So cold and clammy skin is priority for progressive stage.

And the last stage is irreversible, basically meaning death is imminent.

For this part of the video, keep these study guides close by to help you make this knowledge actually stick.

Now there are five types of shock.

The number one most tested is septic shock, caused by widespread bloodborne infection.

Think sepsis infection causes septic shock.

Number two is neurogenic shock, caused by spinal cord injury, T6 or higher.

Number three is hypovolemic shock,

also called hemorrhagic shock, caused by blood loss from a trauma or even a gunshot wound or even from surgery or burns.

So just think blood loss for hypovolemic.

We have low blood volume.

And number four is cardiogenic shock, where the heart fails to pump, like an end -stage heart failure or heart failure exacerbation,

and even an MI heart attack, where we have weak heart muscles and a failed heart pump.

So for cardiogenic shock, just think the cardiac fails.

And lastly, number five is anaphylactic shock, from a severe allergic reaction, like from a bee sting,

or even from eating seafood or something you have an allergy to.

So for anaphylactic, think severe allergic reaction.

Now let's get into these one by one, starting with septic shock pathophysiology.

As mentioned before, this is from sepsis, that widespread blood -borne infection that overwhelms the body,

typically caused by a bacterial infection like pneumonia with an infection inside the lungs

or even a UTI or kidney infection that progressively gets worse and spreads into the bloodstream.

Whatever the cause, a systemic cytokine release inside the bloodstream causes extreme vasodilation and fluid leaking from the capillaries.

So the signs and symptoms include severely low blood pressure.

So once again, the memory trick just think s for shock is for severely

low blood pressure resulting in organ failure from the lack of perfusion

that lack of oxygen

now the key signs to know is obviously low blood pressure less than 80 systolic cool clammy skin

or pale and cool extremities with delayed capillary refill.

Write that one down.

Now, mental status change, huge NCLEX tip.

The big ones to know is confusion and disorientation.

These two signs are typically the result of hypoxemia, or basically meaning low oxygen perfusion,

and high WBC count, over 10 ,000, from the infection, and a temperature high in the initial stages,

and then very, very low, 96 degrees Fahrenheit.

Huge NCLEX tip, so write that down.

Many students get tricked on this since the early stages of the infection, the body's trying to fight off the infection with high core body temperatures.

But the septic shock progresses and very low core body temperature develops.

As well as the other signs too.

Pale, cool extremities, difficulty breathing, and decreased urinary output.

With mental confusion and disorientation, this develops very quickly in the late stages.

So you must report this to the HCP immediately.

Emergency treatment is necessary with intravenous fluids, antibiotics, and other medications.

But again, focus on the signs and symptoms that are bolded here, since these are the most tested.

Now for neurogenic shock.

This is from a spinal cord injury T6 or higher.

Make sure to know that for the NCLEX and your exams.

In neurogenic shock, the autonomic nervous system is damaged, resulting in a blockage of sympathetic nervous system,

which is supposed to speed up the vital signs and cause vasoconstriction.

So only the parasympathetic nervous system is intact, which puts the brakes on the vitals in the parasympathetic nervous system,

causing widespread vasodilation and hypotension.

So naturally, we see low and slow vitals, like a low and slow heart rate and blood pressure,

as vasodilation occurs, making it difficult for blood to return back to the heart.

This decreased blood flow back to the heart leads to decreased blood flow out of the heart,

basically decreased cardiac output, meaning less oxygenated blood out of the heart and to the body.

This results in poor tissue perfusion from the lack of oxygen and impaired cell metabolism,

resulting in organ failure and ultimately death.

So the key signs and symptoms to know for neurogenic shock, write this down, is bradycardia, huge NCLEX tip.

This is due to the parasympathetic dominance.

So just think parasympathetic puts the brakes on the vital signs.

So bradycardia results, and this is a very unique sign and symptom.

Unlike other types of shock where the heart rate increases with tachycardia due to compensation,

in neurogenic shock, the sympathetic nervous system is blocked, resulting in this bradycardia.

So Saunders mentions, a client is admitted to the hospital with a diagnosis of neurogenic shock after a traumatic motor vehicle collision.

Which manifestation best characterizes this diagnosis?

bradycardia.

So the top three signs to know for neurogenic shock is obviously number one, a low heart rate, bradycardia less than 60 beats per minute.

So write that one down.

Number two is a low blood pressure, hypotension, less than 80 systolic.

100

And number three, skin that is warm, pink, and dry.

101

Huge NCLEX tip right there.

102

So make sure to write that one down as well.

103

This is mainly from the vasodilation as blood can't return to the heart and ends up pooling inside the body.

104

Now interventions for neurogenic shock, the priority here is IV normal saline or 0 .9 % sodium chloride.

105

We have to do this immediately to perfuse the tissues.

106

Our goal here is to increase the blood pressure and stabilize it in order to perfuse the body.

107

Now for the complications.

108

A little side note here.

109

A deadly complication for any spinal cord injury above T6 is autonomic dysreflexia.

110

Now, we have a full video on this, but just to remind you, we see severe hypertension that can kill the client,

111

typically triggered by a full bladder, constipation, or tight -fitting clothes, basically anything with constriction.

112

Thus, placing a Foley in spinal trauma patients to keep the bladder empty

113

and offering laxatives and loose clothes can usually save a client with T6 injury or higher.

114

But once again, we cover that in the full video for autonomic dysreflexia.

115

Now switching gears to hypovolemic shock.

116

This is caused by anything that can lower the blood volume.

117

So think hypo for low blood or low fluid volume.

118

Typically from excess fluid volume loss through diarrhea, vomiting, or fluid shifts in burn patients.

119

And as mentioned before, from bleeding or hemorrhaging.

120

From a trauma like a gunshot or knife injury.

121

Or even from surgery where we get too much blood loss and even GI bleed.

122

Whatever the cause, the signs and symptoms are typically the same.

123

So the key point to write down is cold, clammy skin.

124

This is priority.

125

Huge NCLEX tip.

126

As mentioned before, this is seen in the progressive stage and is indicating that the client is getting worse.

127

So you must notify the healthcare provider immediately and get some IV normal saline started quickly.

128

So the top three signs to know that our classic indications of hypovolemic shock is number one, hypotension.

129

Just like with any shock, we see severely low blood pressure, less than 80, cystoic.

130

Number two is tachycardia, due to the compensatory mechanisms to maintain the cardiac output and perfusion.

131

And number three is a low central venous pressure, normally between 2 and 6.

132

So anything less than 2 typically means your client is through.

133

Now another classic sign of hypovolemic shock is a low urinary output, due to the fluid volume loss.

134

So just think, 30 mLs per hour or less means the body is in distress.

135

So Kaplan mentions, which vital sign would alert the nurse to potential hemorrhage following a nephrectomy, or basically kidney removal?

136

A heart rate of 110.

137

Yes, that's tachycardia over 100 beats per minute.

138

Now as far as the interventions, the priority is hemodynamic stability.

139

Fancy words for getting that blood pressure up.

140

So number one, we have to lower the head of the bed right away.

141

Huge NCLEX tip right there.

142

So write that down.

143

We do this to bring blood flow back to the brain and the core of the body.

144

So never place the head of the bed in high

145

Fowler's position or place the head of the bed up.

146

Don't let the NCLEX trick you here.

147

This will worsen the low blood pressure and cause even worse hypotension, dropping the blood pressure even more.

148

So the memory trick, put the head low in hypovolemic or hypotension to prevent further hypotension there.

149

And number two is IV normal saline or 0 .9 % sodium chloride.

150

We do this before vasopressor medications.

151

This is a huge key point right here as the fluid bolus will increase intravascular volume

152

and increase blood pressure and perfused tissues.

153

Then only after, then we give the vasopressors like IV norepinephrine and dopamine.

154

Always use second, as these vasopressor drugs mainly press on the vessels to press up the vitals.

155

They do this by increasing blood flow back to the heart to increase the blood pressure.

156

So again, the key point is to give normal saline first

157

so that the vasopressors can press that added fluid back to the heart.

158

Now, initially, the vital signs will improve from the normal saline, but it won't last.

159

So that's why we do norepi and dopamine.

160

This is definitely needed to maintain the blood pressure for long term.

161

Now, another key point here.

162

This one's really critical.

163

Do not delay a new bag of norepinephrine when the first bag is almost done.

164

Huge NCLEX tip.

165

Even if the client is showing signs of improvement with stabilized blood pressure, this is expected initially.

166

But it won't last long term.

167

So remember, do not delay a new bag of norepinephrine when the first one's almost done.

168

Now the goal here is to maintain MAP, that mean arterial pressure,

169

over the key number 65 mmHg which means

170

that the average blood pressure all over the body is adequate for tissue perfusion

171

or in other words to oxygenate the body and keep the organs alive.

172

Now another thing CVP central venous pressure as mentioned before it should be maintained between two to six millimeters of mercury.

173

Less than two means your client is through.

174

Basically they need more fluids

175

And over six needs a fix.

176

They have too much fluid here.

177

So the client needs some diuretics to drain some of that fluid from the body and into the potty.

178

So Saunders mentions, a client in shock develops a central venous pressure of less than two.

179

Which prescribed intervention should the nurse implement first?

180

Increase the rate of intravenous fluids.

181

Yes, less than two, your patient is through.

182

So increase those fluids.

183

and lastly since vasopressors cause narrowing of blood vessels by pressing

184

on the vessels the pulse oximeter is often not accurate

185

when placed on the finger as blood flow is shunted away from the extremities toward the core of the body

186

so be sure to write

187

this down for the spo2 the sensor should be placed on

188

the forehead instead of the extremities since there will be lack of perfusion there next

189

Next is cardiogenic shock.

190

As mentioned before, the heart fails to pump blood out of the heart to the body.

191

Like in a heart attack, where heart muscles die, or even heart failure exacerbation, where the heart fails to pump.

192

So again, think cardiogenic shock as the cardiac fails.

193

And just like with any shock, we see a severe drop in blood pressure.

194

Remember, this one is always the most tested.

195

Saunders mentions, A client having a myocardial infarction, based on the elevated troponin levels,

196

the nurse should alert the HCP because the vital sign changes are most consistent with which complication.

197

Refer to the exhibit.

198

So cardiogenic shock, we have a cardiac problem.

199

And the question mentions a heart attack, an MI, or myocardial infarction.

200

So MI think heart tissues die.

201

The heart fails to pump adequately.

202

So just look at the blood pressure here when clicking on the exhibit.

203

The lower and lower it goes indicates that we have a cardiogenic shock problem.

204

Severely low blood pressure with any type of shock.

205

So the key treatment to help out our failed heart pump is the double D's here.

206

Dopamine and digoxin, which both have inotropic properties, meaning it helps the heart to pump more forcefully.

207

So just think, inotropic is very forceful.

208

Kind of like when you know the answer to something.

209

You're like, I know the answer.

210

It's very, very forceful.

211

So inotropic means a forceful contraction.

212

Now D for dopamine is also a vasopressor

213

which presses down the vessels in vasoconstriction to press up the heart rate and blood pressure.

214

But a big caution here.

215

Our vasopressors can work too well and may cause adverse effects.

216

Like tachycardia, a heart rate over 100 beats per minute, which is a huge NCLEX tip, so write that one down, as well as arrhythmias.

217

But really, the most tested here was tachycardia.

218

Typically means that the dose may need to be lowered.

219

And the next D is for digoxin.

220

Just think, digoxin digs for a deeper contraction here especially for our clients

221

in heart failure who have a failed heart pump with a weaker contraction.

222

And Saunders mentions, A client with heart failure exacerbation and suspected state of shock,

223

the nurse knows which intervention is priority for this client.

224

Administration of digoxin.

225

Yes, we need a dig for that deeper contraction.

226

And lastly here, Anaphylactic shock our severe allergic reaction.

227

Like from a bee sting or even a peanut allergy, again, anaphylactic shock, we have that severe allergic reaction.

228

The key treatment to know for the NCLEX, and write this down, epinephrine or epi -auto -injector.

229

We have to know this and the key points, so let's play a segment from our pharmacology master course.

230

For this lecture, we're talking about anaphylaxis, that severe allergic reaction.

231

We give an EpiPen or aka auto -injector to inject straight into the outer thigh for an IM injection,

232

typically after severe allergic reactions, for example, a bee sting or food allergies.

233

Say we're eating shellfish with an allergy, the client goes into an anaphylactic shock, resulting in deadly hypotension and bronchoconstriction,

234

which inevitably leads to death via cardiac and respiratory arrest.

235

so the key points to know hesse mentions epi is the first drug used for anaphylaxis

236

and ati backs this up by saying first signs of anaphylaxis reaction those hives dyspnea

237

and hypotension we use an epi pen

238

so the key term here to know is it's the first drug for the first sign of anaphylactic reaction

239

we always use epi first now two big enclex tips we repeat every 5 to 15 minutes

240

if the signs and symptoms continue and we repeat epi until the signs

241

and symptoms resolve so we keep on repeating epi until those signs

242

and symptoms go away then we give the other medications

243

and in the enclex world we just keep on giving this drug forever until those symptoms resolve Thank you.

244

Now, how do you know if it's a supersized anaphylactic reaction and not just a mild allergic reaction?

245

Well, any allergy that affects the ABCs, the airway, breathing, and circulation,

246

or even induces hives, this is deadly anaphylaxis, the supersized allergy reaction.

247

So again, don't delay epi injection.

248

We inject immediately upon these signs and symptoms.

249

And no skin prep is necessary.

250

Just stab that outer thigh straight through the pants and hold it there for about 10 seconds.

251

So the correct medication sequence is epi first, then diphenhydramine, or basically Benadryl, and lastly, albuterol and steroids.

252

But out of all these, most question banks only stress about epi being that first drug during anaphylaxis.

253

And the rest, only after the acute signs and symptoms have resolved.

254

Remember, we repeat epi as a priority until those signs and symptoms resolve.

255

Now, Kaplan mentions a patient scenario.

256

Administration of ampicillin and the client reports itchiness and difficulty breathing.

257

The priority actions is number one, stop the infusion that's causing the problem number two you assess by auscultating the lungs

258

or listening to the lungs and number three you prepare to administer epinephrine first

259

so again not steroids not albuterol it's always epi first

260

and secondly the capman mentions effective management of shock you have a bp that's a little bit high apical pulse

261

that is 99 and a cap refill that's less than two seconds guys this indicates good perfusion,

262

meaning epi is doing its job to press on the veins as a vasopressor.

263

So it's pressing those vital signs up.

264

And speaking of, normal expected side effects to know after giving this medication.

265

Tachycardia, that heart rate over 100, palpitations, and dizziness.

266

Again, these side effects means that epi is doing its job to prevent that shock, or basically that death from low blood pressure.

267

Now for patient education, how to use the EpiPen, the three big key points here.

268

Number one, we inject into the outer thigh at a 90 degree angle on the onset of symptoms.

269

So Hesse mentions we stab the pen into the outer thigh and we hold it in place for about 10 seconds.

270

So not five seconds, not three seconds, but a full 10 seconds here.

271

Now number two is we seek immediate medical attention after use.

272

So go to the hospital.

273

Don't wait since epi wears off in about 10 to 20 minutes and signs and symptoms may return.

274

Lastly, number three, this is a big one here.

275

Store epi pens in a dark place at room temperature.

276

So not too cold, not too hot.

277

So not in a refrigerator and not in a car, since this medication can be deactivated by heat and light.

278
