NCLEX-RN Exam Practice Questions
Extract:
Question 1 of 5
A client returns to the cardiovascular intensive care unit following his coronary artery bypass graft. In planning his care, the most important electrolyte the nurse needs to monitor will be:
Correct Answer: C
Rationale: Potassium will need to be closely monitored because of its effects on the heart. Hypokalemia could result in supraventricular tachyarrhythmias.
Question 2 of 5
On admission to the inpatient unit, a 34-year-old client is able to follow simple directions, but with great difficulty. He is worried about how he can keep clean in such a public place and repeatedly dusts his bureau, straightens his bed, and adjusts the clothes in his closet. The client is experiencing a severe level of anxiety. Which response by the nurse would be most therapeutic in initially attempting to reduce his anxiety?
Correct Answer: B
Rationale: Acknowledging the anxiety and channeling it into some positive activity, such as a unit tour, is therapeutic and helps reduce anxiety by providing distraction and orientation.
Question 3 of 5
A 20-year-old female has a prescription for Sumycin (tetracycline). While teaching the client how to take her medicine, the nurse learns that the client is also taking an oral contraceptive. Which instruction should be included in the teaching plan?
Correct Answer: D
Rationale: Tetracyclines can reduce the effectiveness of oral contraceptives by altering gut flora, affecting estrogen metabolism. This increases the risk of unintended pregnancy, requiring backup contraception.
Question 4 of 5
A female client has been diagnosed with chronic renal failure. She is a candidate for either peritoneal dialysis or hemodialysis and must make a choice between the two. Which information should the nurse give her to help her decide?
Correct Answer: A
Rationale: Hemodialysis is faster in clearing the blood of toxins than peritoneal dialysis. However, clients must consider the time that they spend traveling to the dialysis center and the disruption in their daily lives. Peritoneal dialysis requires several exchanges with dwelling time for the dialysate and therefore takes longer than hemodialysis. Several serious complications of peritoneal dialysis include peritonitis, catheter displacement and/or plugging, or pain during dialysis. A client can be taught to self-administer peritoneal dialysis without the aid of a professional.
Question 5 of 5
The nurse is caring for a client with a history of multiple sclerosis. Which intervention is most appropriate to prevent complications?
Correct Answer: C
Rationale: Hot baths can exacerbate multiple sclerosis symptoms by increasing body temperature, causing fatigue or weakness. Weight-bearing exercise is encouraged, antibiotics are not routine, and fluid restriction is harmful.
