Category: Physiological Adaptation
The nurse is aware that the following terms used to describe reduced cardiac
output and perfusion impairment due to ineffective pumping of the heart is:
A. Anaphylactic shock
Incorrect
B. Cardiogenic shock
Correct Answer
C. Distributive shock
D. Myocardial infarction (MI)
Incorrect
Correct Answer: B. Cardiogenic shock
Cardiogenic shock is shock related to ineffective pumping of the heart.
,Option A: Anaphylactic shock results from an allergic reaction. This severe
reaction happens when an over-release of chemicals puts the person into shock.
Option C: Distributive shock results from changes in the intravascular volume
distribution and is usually associated with increased cardiac output.
Option D: MI isn’t a shock state, though in most cases, a lack of oxygen to the
heart, usually from a heart attack, damages its main pumping chamber. Without
oxygen-rich blood circulating to that area of the heart, the heart muscle can
weaken and go into cardiogenic shock.
2. Question1 point(s)
Category: Physiological Adaptation
A client with hypertension asks the nurse which factors can cause blood pressure
to drop to normal levels?
A. Kidneys’ excretion to sodium only.
B. Kidneys’ retention of sodium and water.
C. Kidneys’ excretion of sodium and water.
Correct
D. Kidneys’ retention of sodium and excretion of water.
Correct
Correct Answer: C. Kidneys’ excretion of sodium and water.
,The kidneys respond to rise in blood pressure by excreting sodium and excess
water. This response ultimately affects systolic blood pressure by regulating blood
volume.
Option A: As the kidneys excrete sodium, water also goes along with it.
Option B: Sodium or water retention would only further increase blood pressure.
Option D: Sodium and water travel together across the membrane in the kidneys;
one can’t travel without the other.
3. Question1 point(s)
Category: Pharmacological and Parenteral Therapies
Nurse Rose is aware that the statement that best explains why furosemide (Lasix)
is administered to treat hypertension is:
A. It dilates peripheral blood vessels.
B. It decreases sympathetic cardio acceleration.
C. It inhibits the angiotensin-converting enzymes.
D. It inhibits the reabsorption of sodium and water in the loop of Henle.
Correct
, Correct
Correct Answer: D. It inhibits the reabsorption of sodium and water in the loop of
Henle.
Furosemide is a loop diuretic that inhibits sodium and water reabsorption in the
loop Henle, thereby causing a decrease in blood pressure.
Option A: Vasodilators cause dilation of peripheral blood vessels, directly relaxing
vascular smooth muscle and decreasing blood pressure.
Option B: Adrenergic blockers decrease sympathetic cardio acceleration and
decrease blood pressure.
Option C: Angiotensin-converting enzyme inhibitors decrease blood pressure due
to their action on angiotensin.

Category: Reduction of Risk Potential
Nurse Nikki knows that laboratory results supports the diagnosis of systemic lupus
erythematosus (SLE) is:
A. Elevated serum complement level
B. Thrombocytosis, elevated sedimentation rate
