WGU D116 ACTUAL EXAM FULL QUESTIONS
AND CORRECT ANSWERS GRADED A PLUS
●● A patient is taking a drug that interferes with venous constriction.
What should the nurse tell the patient?
Answer: 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 __________.
Answer: 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?
,Answer: 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?
Answer: "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.)
Answer: 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?
Answer: Captopril (ACE inhibitor) and spironolactone (potassium-
sparing diuretic)
