Which medication class would be prescribed for palpitations?
Correct Answer:<<
Beta-blockers
A patient is taking a drug that interferes with venous constriction.
What should the nurse tell the patient?
Correct 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 __________.
Correct 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?
Correct 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?
Correct 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.)
Correct 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?
Correct Answer:<<
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?
Correct Answer:<<
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 __________.
Correct Answer:<<
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?
, Correct Answer:<<
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?
Correct Answer:<<
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?
Correct Answer:<<
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?
Correct Answer:<<
"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
