NCLEX-RN Exam Questions
Extract:
Question 1 of 5
A dose of theophylline may need to be altered if a client with COPD:
Correct Answer: D
Rationale: The effects of morphine or an allergic response to the drug will not affect theophylline clearance. Xanthines are used cautiously in clients with severe cardiac disease, liver disease, cor pulmonale, hypertension, or hyperthyroidism. Arthritis does not influence the dosage of theophylline. Theophylline does not cause sedation or drowsiness. Conversely, its side effects may be exhibited by central nervous system stimulation. Cimetidine decreases theophylline clearance from the system and increases theophylline levels in the blood, thus increasing the risk of toxicity.
Question 2 of 5
When preparing a client for magnetic resonance imaging, the nurse should implement which of the following?
Correct Answer: C
Rationale: Removing jewelry and checking for metal implants prevents MRI-related injuries due to magnetic fields. Consent and atropine (
A), scrubbing (
B), and Benadryl (
D) are not standard for MRI prep.
Question 3 of 5
A 54-year-old client is admitted to the hospital with a possible gastric ulcer. He is a heavy smoker. When discussing his smoking habits with him, the nurse should advise him to:
Correct Answer: C
Rationale: Smoking on a full stomach minimizes nicotine's effect on gastric acid, reducing ulcer irritation. Other options still stimulate gastric acid secretion.
Question 4 of 5
The nurse is caring for a client with a history of a fractured pelvis who is in skeletal traction. The nurse should:
Correct Answer: D
Rationale: Monitoring for infection at pin sites prevents osteomyelitis in skeletal traction. Turning is limited, weights must hang freely, and lotion is unnecessary.
Question 5 of 5
A female client at 36 weeks' gestation is experiencing preterm labor. Her physician has prescribed two doses of betamethasone 12 mg IM q24h. The nurse explains that she is receiving this drug to:
Correct Answer: C
Rationale: Respiratory distress syndrome occurs in the newborn, not the fetus. It may be treated postnatally with surfactant therapy. Betamethasone is a corticosteroid, not an anti-infective drug; therefore, its use would not prevent uterine infection. Betamethasone binds with glucocorticoid receptors in alveolar cells to increase production of surfactant, thus increasing lung maturity in the preterm fetus. Betamethasone does not affect uteroplacental circulatory exchange.
