Cardiovascular Medications
Question: A nurse is caring for a client who has
a new prescription for warfarin. Which of the
following laboratory tests should the nurse
review prior to administration?
A. PT
B. Total iron-binding capacity
C. WBC
D. PTT
☑VERIFIED ANSWER: A. PT. Warfarin therapy is
monitored using Prothrombin Time (PT) and
International Normalized Ratio (INR), which
,measure the extrinsic coagulation pathway. PTT
is used to monitor heparin therapy.
Question: A nurse is caring for a client receiving
digoxin and furosemide. Which finding requires
immediate intervention?
A. Heart rate 58/min
B. Serum potassium 3.0 mEq/L
C. Blood pressure 130/78 mm Hg
D. Urine output 50 mL/hr
☑VERIFIED ANSWER: B. Serum potassium 3.0
mEq/L. Hypokalemia (K+ <3.5 mEq/L)
significantly increases the risk of digoxin
toxicity. Furosemide causes potassium loss, and
low potassium potentiates digoxin's effects,
increasing the risk of life-threatening
dysrhythmias.
Question: A nurse is teaching a client about
nitroglycerin sublingual tablets. Which
,statement by the client indicates
understanding?
A. "I will sit down before taking this
medication."
B. "I can take up to five doses if chest pain
persists."
C. "I will call 911 if pain is not relieved after one
dose."
D. "I should store the tablets in a plastic bag."
☑VERIFIED ANSWER: A. "I will sit down before
taking this medication." Clients should sit
before taking nitroglycerin to avoid hypotension
and dizziness. They can take up to 3 doses at 5-
minute intervals. If pain is not relieved after the
first dose, they should call 911. Tablets must be
stored in the original glass container, not
plastic.
, Question: A client is prescribed enalapril.
Which adverse effect should the nurse monitor
for?
A. Ecchymosis
B. Jaundice
C. Hypotension
D. Hyperkalemia
☑VERIFIED ANSWER: C. Hypotension. Enalapril
is an ACE inhibitor that causes vasodilation,
leading to hypotension. The nurse should
monitor blood pressure, especially after the
first dose. Other adverse effects include
hyperkalemia and cough.
Question: A nurse is caring for a client with a
new prescription for spironolactone. The nurse
notes the client's serum potassium is 5.5
mEq/L. What action should the nurse take?
A. Administer the medication as prescribed
