NCLEX RN Predictor Exam Questions
Extract:
Question 1 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.
Question 2 of 5
The nurse is caring for a client with a head injury who has increased ICP. The physician plans to reduce the cerebral edema by constricting cerebral blood vessels. Which physician order would serve this purpose?
Correct Answer: A
Rationale: Hyperventilation reduces PaCO2, causing cerebral vasoconstriction and decreased ICP. Shunts (
B) drain CSF, Furosemide (
C) reduces fluid volume, and Solu medrol (
D) reduces inflammation, but none constrict vessels directly.
Question 3 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 4 of 5
During a client's first postpartum day, the nurse assessed that the fundus was located laterally to the umbilicus. This may be due to:
Correct Answer: D
Rationale: (A,
B) Endometritis, urine retention, or bladder distention provide good distractors because they may delay involution but do not usually cause the uterus to be lateral. Bowel distention and constipation are common in the postpartum period but do not displace the uterus laterally. Urine retention or bladder distention commonly displaces the uterus to the right and may delay involution.
Question 5 of 5
Two hours after the second injection of haloperidol, a client complains to the nurse of a stiff neck and inability to sit still. He is experiencing symptoms consistent with:
Correct Answer: B
Rationale: Stiff neck is consistent with a dystonic reaction, but the client has no symptoms of drooling, shuffling gait, or pill-rolling movements characteristic of parkinsonism. Stiff neck is consistent with a dystonic reaction, and inability to sit still with varying degrees of psychomotor agitation is characteristic of akathisia. The client has symptoms of dystonia but not of parkinsonism. The client has none of the characteristic symptoms of neuroleptic malignant syndrome: hyperpyrexia, generalized muscle rigidity, mutism, obtundation, agitation, sweating, increased blood pressure and pulse.
