WITH CORRECT VERIFIED SOLUTIONS
100% GUARANTEED PASS
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? -
ANS ✓Captopril (ACE inhibitor) and spironolactone (potassium-sparing diuretic)
ACE inhibitors increase the risk of hyperkalaemia and combining this drug
with a potassium-sparking diuretic creates a significant risk of
hyperkalaemia
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? - ANS
✓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 __________. - ANS ✓Prevent reflex tachycardia
Beta-blockers do not reduce flushing, minimize gingival hyperplasia, or
prevent constipation

Beta-blockers reduce adverse cardiac effects of nifedipine
Explain what verapamil does? - ANS ✓Used to treat both vasospastic angina
and angina of effort
Slows ventricular rate in patients with a flutter, a fib, and paroxysmal
supraventricular tachycardia
First-line drug for the tx of essential htn
A nurse is caring for a patient who is receiving verapamil for hypertension
and digoxin for heart failure.
What should the provider ask the nurse to observe this patient for? - ANS
✓AV Blockade
Verapamil and digoxin both suppress impulse conduction through the AV
node; when used together the risk of AV blockade is increased
Verapamil and digoxin both suppress heart rate
Nifedipine causes reflex tachycardia
A patient is admitted with severe hypertensive crisis.
Which medication should the provider order? - ANS ✓Sodium nitroprusside
IV
Drug of choice for hypertensive emergencies and is given IV.
A patient asks the provider how nitroglycerin works to relieve anginal pain.

Which statement is a correct response from the provider? - ANS
✓"Nitroglycerin promotes vasodilation, which reduces preload and oxygen
demand"
Dilates the veins, which reduces venous return to the heart, which in turn
decreases ventricular filling
A patient with angina who is taking ranolazine has developed a respiratory
infection and a dysrhythmia. The provider has ordered azithromycin for
the infection and amlodipine for the dysrhythmia. A nursing student caring
for this patient tells the nurse that the patient's heart rate is 70 beats per
minute and the blood pressure is 128/80 mm Hg. The nurse asks the
student to discuss the plan for this patient's care.
Which action is correct? - ANS ✓Question the order for azithromycin
Azithromycin is CYP3A4 inhibitor which will decrease metabolism and
enhance effects of ranolazine-puts pt at risk for torsades
A patient with volume overload begins taking a thiazide diuretic.
The provider tells the patient to expect which outcome when taking this
drug? - ANS ✓Improved exercise tolerance
Diuretics help reduce fluid volume overload, which can improve exercise
tolerance by reducing pulmonary edema
A nurse is discussing heart failure with a group of nursing students.
Which statement by a student reflects an understanding of how
compensatory mechanisms can compound existing problems in patients
with heart failure? - ANS ✓"When the heart rate increases to increase cardiac
output, it can prevent adequate filling of the ventricles"
Increase in arteriole tone improves tissue perfusion but also increases both
the resistance to the pumping of the heart and the cardiac workload
