Mock NCLEX RN Exam Questions
Extract:
Question 1 of 5
The client is diagnosed with glaucoma. Which medication is most likely to be prescribed?
Correct Answer: A
Rationale: Timolol, a beta-blocker, is commonly prescribed for glaucoma to reduce intraocular pressure by decreasing aqueous humor production. Atropine increases pressure, pilocarpine is less common, and acetazolamide is used acutely.
Question 2 of 5
A 78-year-old female client has a total hip arthroplasty. Her nurse should know that which of the following is contraindicated?
Correct Answer: B
Rationale: Exercising the unaffected extremities will prevent contractures and emboli. Crossing and uncrossing the affected leg after surgery can dislocate the joint. Neurological and circulatory status of the affected leg has been compromised by surgery. Hourly checks are needed to monitor the status of the leg. A trochanter roll will prevent the upper thigh from rolling outward, increasing the chances of dislocation.
Question 3 of 5
What specific hormone must be present in serum or urine laboratory tests used to diagnose pregnancy?
Correct Answer: A
Rationale: Human chorionic gonadotropin is the biochemical basis for pregnancy tests, produced by the placenta to maintain the corpus luteum.
Question 4 of 5
The nurse is caring for a client with a history of a pleural effusion who is scheduled for a thoracentesis. The nurse should:
Correct Answer: C
Rationale: Sitting upright with arms supported facilitates access to the pleural space during thoracentesis and reduces complications. Sedatives and fluid restrictions are not routine.
Question 5 of 5
The obstetric client's fetal heart rate is 80-90 during the contractions. The first action the nurse should take is:
Correct Answer: B
Rationale: A fetal heart rate of 80-90 during contractions indicates bradycardia possibly from cord compression or uteroplacental insufficiency. Turning the client to her left side improves placental perfusion and is the first action.
