NCLEX RN Nursing Exam Questions

Extract:


Question 1 of 5

The nurse is reviewing the results of a sweat test taken from a child with cystic fibrosis. Which finding supports the client's diagnosis?

Correct Answer: B

Rationale: A sweat chloride concentration >60 mEq/L is diagnostic for cystic fibrosis due to defective chloride channels. Potassium levels are not diagnostic, and low chloride is normal.

Question 2 of 5

The client admitted with angina is given a prescription for nitroglycerine. The client should be instructed to:

Correct Answer: C

Rationale: Nitroglycerin should be stored in its original brown bottle to protect it from light and maintain potency. Replenishing every three months is not standard taking tablets every 15 minutes is incorrect (typically every 5 minutes up to 3 doses) and crushing is not appropriate.

Question 3 of 5

The nurse is in the hallway and one of the visitors faints. The nurse should:

Correct Answer: B

Rationale: Sitting the client up defeats the goal of re-establishing cerebral blood flow. Elevating the legs anatomically redirects blood flow to the cerebral area. This strategy is a nice general comfort measure after the victim has regained consciousness. This strategy is not as effective a strategy in helping the client to regain consciousness as elevating the legs.

Question 4 of 5

The nurse is performing a neurological assessment on a client admitted with TIAs. Assessment findings reveal an absence of the gag reflex. The nurse suspects injury to which of the following cranial nerves?

Correct Answer: B

Rationale: The vagus nerve (X) innervates the pharynx and larynx, contributing to the gag reflex. Absence of the gag reflex suggests vagus nerve injury. Hypoglossal (XII) controls tongue movement, glossopharyngeal (IX) aids taste and swallowing, and facial (VII) controls facial muscles.

Question 5 of 5

The nurse is caring for a client with a diagnosis of gestational trophoblastic disease. Which laboratory value is most likely to be elevated?

Correct Answer: A

Rationale: Gestational trophoblastic disease (e.g. molar pregnancy) causes markedly elevated hCG levels due to abnormal trophoblastic tissue growth. AFP estriol and progesterone are not typically elevated in this condition.
