Shock

Question 1

As in all types of shock, _____ blood pressure is a key finding in patients with obstructive shock.[3][9] In response to low blood pressure, heart rate increases. Shortness of breath, tachypnea, and hypoxia may be present. Because of poor blood flow to the tissues, patients may have cold extremities. Less blood to the kidneys and brain can cause decreased urine output and altered mental status, respectively.[9]

Answer 1

Low

JVD is another possible sign but this is also a sign seen in both cardiogenic and obstructive shock (but JVD is not seen in hypovolemic or distributive)

Question 2

ptnt is vomiting bl. first set of vital sings p100, RR 24, BP 154/64.
second set vitals, the p increased to 122, the RR increased to 28, but BP stayed the same. what kind of shock?

Answer 2

compensated shock

• my guess, this is not decompensated shock because the BP hasn’t dropped.

and not obstructive shock also because the BP didn’t significantly drop.
also, with obstructive and cardiogenic, i think maybe we’d see more huge increase in P and big drop in BP.

irreversible shock the ptnt is near dying, likely unconscious, severe hypotension, HR begins to decrease.

Question 3

compensated shock

Answer 3

pre-shock

think stably unstable. with BP normal and persisting HR shift

Question 4

decompensated shock

Answer 4

think unstably unstable. BP drops and HR shifts.

Question 5

in a heart attack note these possible symptoms:

Answer 5

this doesn’t necessarily mean cardiac arrest, meaning the heart may continue to beat although it may increase (tachycardia), or it could even remain normal.
listen for heart rate shifts (changes).

a heart attack may increase adrenaline, which may also cause tachycardia and hypertension.

another sign of a heart attack, heart angina.

also, sweating.

and what feels like heartburn/acid, nausea, vomiting.

and dizziness.
and shortness of breath.

there may also be pain in the left jaw, left shoulder, or left arm.

Question 6

hypovolemic shock

Answer 6

Hypovolemic shock is an emergency condition in which severe blood or fluid loss makes the heart unable to pump enough blood to the body. This type of shock can cause many organs to stop working.

Hypovolemia can be recognized by a fast heart rate, low blood pressure, and the absence of perfusion as assessed by skin signs (skin turning pale) and/or capillary refill on forehead, lips and nail beds. The patient may feel dizzy, faint, nauseated, or very thirsty

hosp treatment may include IV fluids or giving bl.

Question 7

What happens to blood pressure during hypovolemic (hemorrhagic) shock?

Answer 7

At first, your diastolic (bottom or second number) blood pressure increases. As you keep losing blood or fluids, your systolic (top or first number) blood pressure comes down

Question 8

hypoglycemia can cause what kind of shock:

hint, its NOT hypovolemic.

Question 9

most likely happening in a trauma ptnt with increasing bp and decreasing hr, and irreg resp’s

Answer 9

prob increasing intracranial pressure

its NOT hemorraghic shock as i’d thought at least

Question 10

motorcycle accident, ptnt thrown, (U), P42, BP 84, RR 12. what type of shock:

obstructive

hypovolemic (incorrect)

neurogenic (prob the one)

Question 11

trauma ptnt, cool clammy skin, stable bp. pulse and rr is rapid. this patient is:

decompensated shock with anaerobic metabolis

compensated shock with anaerobic metabolism

Answer 11

compensated -

I think the key here is the bp is stable. if that starts dropping it gets into unstably unstable decompensated shock.

Question 12

ptnt with sob, diaphoresis, hypot, altered mental state, prior heart issues, angina.
which kind of shock?

Answer 12

cardiogenic

Question 13

severe hypoglycemia could cause what shock?

Answer 13

neurogenic

Question 14

supine hypotensive syndrome (inferior vena cava syndrome)

Answer 14

a pregnant womans baby pushes against the inf vena cava when supine
