WGU D116 Unit 4 Questions with Verified
Correct Answers
Which medication class would be prescribed for palpitations?
Beta-blockers
A patient is taking a drug that interferes with venous constriction.
What should the nurse tell the patient?
Ask for assistance when getting out of bed
Drop in venous pressure reduces venous return to the heart which will pool in the extremities
and orthostatic hypotension can happen.
Bradycardia, ha, and SOB are not expected effects
A patient is taking a beta1-adrenergic drug to improve the stroke volume of the heart.
This drug acts by increasing __________.
Myocardial contractility
Cardiac afterload is determined primarily by the degree of peripheral resistance caused by
constriction of arterioles; increasing afterload would decrease stroke volume
A patient with a history of hypertension is admitted for a procedure.
If the patient's arterial pressure decreases, which clinical manifestation would you
expect to see?
Increased HR
,When arterial pressure decreases, the vasoconstrictor center causes constriction of nearly all
arterioles, leading to an increase in peripheral resistance, constriction of veins, increasing
venous return, and increased HR
You are teaching a nursing student how blood can return to the heart when pressure in
the venous capillary beds is very low.
Which statement by the student indicates a need for further teaching?
"Skeletal muscles relax to allow the free flow of blood"
Skeletal muscle CONTRACTION, along with one-way venous valves, help create an
"auxiliary" venous pump that helps drive blood toward the heart
Constriction of small muscles in venous walls helps increase venous pressure
Negative pressure in the left atrium sucks blood toward the heart
Values (one-way) work with the contraction of skeletal muscles to create a venous pump
Besides having diuretic effects for patients with congestive heart failure, thiazides are
also used to treat what? (Select three.)
Diabetes insipidus
Hepatic failure
Postmenopausal osteoporosis
, Paradoxical effect of reducing urine output in patients with diabetes insipidus
Mobilize edema associated with liver disease
Promote tubular reabsorption of calcium which can reduce the risk of osteoporosis in
postmenopausal women
The provider is reviewing a patient's medications before administration. Which drug-
to-drug interactions should most concern the provider in a patient with a history of
heart failure and a potassium level of 5.5 mEq/L?
Captopril (ACE inhibitor) and spironolactone (potassium-sparing diuretic)
ACE inhibitors increase the risk of hyperkalemia and combining this drug with a potassium-
sparking diuretic creates a significant risk of hyperkalemia
A patient with hypertension is taking furosemide for congestive heart failure. The
prescriber orders digoxin to help increase cardiac output.
What other medication should be ordered for this patient?
Spironolactone (Potassium-sparing)
Spironolactone is used in conjunction with furosemide because of being potassium sparing.
Hydrochlorothiazide, bumetanide, chlorothiazide all (potassium-wasting)
A patient begins taking nifedipine, along with metoprolol, to treat hypertension.
The metoprolol is used to __________.
