Cardiac System NCLEX Questions Questions
Extract:
Question 1 of 5
The nurse obtains adult blood pressure readings on four separate clients. Which client should have a follow-up blood pressure check within 2 months?
Correct Answer: B,C
Rationale: A blood pressure of 132/98 mm Hg indicates stage 1 hypertension (systolic 130-139 or diastolic 90-99 mm Hg), requiring follow-up within 2 months to monitor and manage. The other readings are either normal (118/78) or prehypertension (138/88), which may not require such urgent follow-up.
Question 2 of 5
The nurse is caring for a client who is receiving heparin. What drug should be readily available?
Correct Answer: D
Rationale: The antidote for heparin is protamine sulfate. Vitamin K is the antidote for warfarin. Calcium gluconate is used for magnesium sulfate overdose. Caffeine is a stimulant and not an antidote.
Question 3 of 5
An adult who is admitted for a cardiac catheterization asks the nurse if she will be asleep during the cardiac catheterization. What is the best initial response for the nurse to make?
Correct Answer: B
Rationale: During cardiac catheterization, clients receive sedation but remain awake, as their cooperation may be needed. General anesthesia is not used, and pain is managed with sedation, not additional anesthetics. Asking 'why' may make the client defensive and does not provide the requested information.
Question 4 of 5
A low-sodium diet has been ordered for an adult client. The nurse knows that the client understands his low-sodium diet when the client selects which menu?
Correct Answer: B
Rationale: Baked chicken, mashed potatoes, and green beans are naturally low in sodium. Steak, hot dogs, and chicken noodle soup are typically high in sodium.
Question 5 of 5
The nurse checking the client's leg incision is aware that which is the most common blood vessel used in CABG surgery?
