NCLEX-RN Exam Practice Questions
Extract:
Question 1 of 5
The sputum of a client remains positive for the tubercle bacillus even though the client has been taking Laniazid (isoniazid) in combination with other antituberculars. The nurse recognizes that the client taking isoniazid should have a negative sputum culture within:
Correct Answer: D
Rationale: Effective antitubercular therapy, including isoniazid, typically results in a negative sputum culture within three months, indicating control of active infection.
Question 2 of 5
The physician has ordered an amniocentesis to determine the L/S ratio. The L/S ratio is a reliable indicator of:
Correct Answer: C
Rationale: The lecithin/sphingomyelin (L/S) ratio assesses fetal lung maturity by measuring surfactant levels in amniotic fluid. A ratio of 2:1 or higher indicates mature lungs reducing the risk of respiratory distress syndrome. It does not assess renal function Rh isoimmunization or anatomical abnormalities.
Question 3 of 5
The nurse is discharging a client with a prescription of eyedrops.
Correct Answer: B
Rationale: Administering a second eyedrop immediately (
B) prevents absorption of the first, indicating a need for teaching (wait 5–10 minutes). Shaking (
A), hand washing (
C), and proper instillation (
D) are correct.
Question 4 of 5
The client is prescribed tamsulosin (Flomax) for benign prostatic hyperplasia. Which side effect should the nurse monitor for?
Correct Answer: B
Rationale: Tamsulosin, an alpha-blocker, causes vasodilation, leading to orthostatic hypotension as a common side effect. Hypotension (not hypertension), bradycardia, and hyperglycemia are less likely.
Question 5 of 5
A nurse is caring for a client with a myocardial infarction. The nurse recognizes that the most common complication in the client following a myocardial infarction is:
Correct Answer: B
Rationale: Cardiac dysrhythmias are the most common complication post-MI due to ischemic damage to the conduction system. Hypertrophy develops later, and hyperkalemia is less common.
