NCLEX RN Predictor Exam Questions
Extract:
Question 1 of 5
When administering total parenteral nutrition, the nurse should assess the client for signs of rebound hypoglycemia. The nurse knows that rebound hypoglycemia occurs when:
Correct Answer: B
Rationale: Rebound hypoglycemia occurs when TPN is stopped abruptly, causing a rapid drop in blood glucose due to persistent insulin release. Tapering the infusion prevents this.
Question 2 of 5
The child with iron poisoning is given IV deferoxamine mesylate (Desferal). Following administration, the child suffers hypotension, facial flushing, and urticaria. The initial nursing intervention would be to:
Correct Answer: B
Rationale: The IV line should not be discontinued because other IV medications will be needed. Stop the medication and begin a normal saline infusion. The child is exhibiting signs of an allergic reaction and could go into shock if the medication is not stopped. The line should be kept opened for other medication. Taking vital signs and reporting to the physician is not an adequate intervention because the IV medication continues to flow. Assessing urinary output and, if it is 30 mL an hour, maintaining current treatment is an inappropriate intervention owing to the child's obvious allergic reaction.
Question 3 of 5
A client with a history of a lumbar laminectomy is being discharged. The nurse should teach the client to avoid:
Correct Answer: A
Rationale: Bending at the waist post-lumbar laminectomy strains the surgical site, risking injury. Sleeping, walking, and sitting (if brief) are generally safe with proper technique.
Question 4 of 5
A couple is planning the conception of their first child. The wife, whose normal menstrual cycle is 34 days in length, correctly identifies the time that she is most likely to ovulate if she states that ovulation should occur on day:
Correct Answer: C
Rationale: Ovulation occurs 14 ± 2 days before the next menses; in a 34-day cycle, this is day 20 ± 2.
Question 5 of 5
Which vitamin should be administered with INH (isoniazid) in order to prevent possible nervous system side effects?
Correct Answer: C
Rationale: Isoniazid can cause peripheral neuropathy by depleting vitamin B6 (pyridoxine), so supplemental pyridoxine is given to prevent this side effect.
