NCLEX RN Exam Review Answers

1. A client on lithium has diarrhea and vomiting. What should the nurse do first?

A. Recognize this as a drug interaction
B. Give the client Cogentin
C. Reassure the client that these are common side effects of lithium therapy
D. Hold the next dose and obtain an order for a stat serum lithium level

Correct answer: D

Rationale: Diarrhea and vomiting are manifestations of lithium toxicity. The priority action for the nurse is to hold the next dose of lithium and obtain an order for a stat serum lithium level to confirm toxicity. This ensures patient safety and prevents further harm. Recognizing it as a drug interaction is not the first step in this scenario. Cogentin is used to manage extrapyramidal symptoms (EPS) associated with antipsychotics, not lithium toxicity. Reassuring the client about these symptoms as common side effects of lithium therapy is inappropriate as they indicate a more serious issue than typical side effects like hand tremors, nausea, polyuria, and polydipsia.

2. The client with multiple sclerosis is being educated by the nurse on exercises and physical activities. Which statement by the client indicates a need for further teaching?

A. "I can lift weights and engage in resistance training."?
B. "I should exercise until I am exhausted."?
C. "I can incorporate aerobic exercises into my routine."?
D. "I should perform proper stretching before starting my routine."?

Correct answer: B

Rationale: The correct answer is, "I should exercise until I am exhausted."? This statement indicates a need for further teaching because patients with multiple sclerosis should avoid exercising to the point of exhaustion or fatigue. Strenuous physical activity can increase body temperature and potentially worsen symptoms in individuals with multiple sclerosis. Choice A is correct because lifting weights and resistance training can be appropriate exercises for patients with multiple sclerosis. Choice C is valid because aerobic exercises can also be beneficial. Choice D is accurate as proper stretching before starting an exercise routine is essential for preventing injuries.

3. Plantar flexion can be prevented with ________________.

A. foot soaks
B. foot boards
C. toenail care
D. proper shoes

Correct answer: B

Rationale: Plantar flexion, or foot drop, can be prevented with foot boards, special splints, and range of motion exercises. Foot boards help maintain the foot in a neutral position, preventing contractures and deformities. Foot soaks (choice A) may help with foot hygiene but do not directly prevent plantar flexion. Toenail care (choice C) is important for overall foot health but does not prevent plantar flexion. Proper shoes (choice D) are essential for foot support and comfort but do not specifically prevent plantar flexion.

4. Which of the following statements best describes compartment syndrome?

A. An injury causes pain and tingling that starts in the buttock and travels down the leg.
B. An injury causes swelling within muscle tissue that leads to anoxia of nerves and muscles.
C. An injury causes permanent flexion of the interphalangeal joint, resulting in deformity.
D. An injury causes pain and swelling of the median plantar nerve.

Correct answer: B

Rationale: Compartment syndrome is characterized by swelling and increased pressure within a muscle compartment, leading to decreased blood flow and oxygen supply to nerves and muscles. This can result from various causes, such as trauma or the application of a cast after a fracture. If left untreated, compartment syndrome can lead to tissue necrosis. Choice A is incorrect as pain and tingling starting in the buttock and traveling down the leg are not specific features of compartment syndrome. Choice C is incorrect as permanent flexion of the interphalangeal joint is unrelated to compartment syndrome. Choice D is incorrect as pain and swelling of the median plantar nerve do not describe compartment syndrome.

5. Who typically owns a patient's medical record?

A. The patient
B. The physician
C. The Legal Counsel of the Office
D. No one owns a medical record

Correct answer: B

Rationale: The correct answer is 'The physician.' Physicians typically own their patients' medical records as they are the ones responsible for creating, updating, and maintaining these records. However, it is essential to note that patients have the legal right to access and obtain copies of their medical records. Choice A ('The patient') is incorrect as patients do not own their medical records, but they do have rights regarding access to them. Choice C ('The Legal Counsel of the Office') is incorrect as legal counsel typically do not own or have ownership rights over medical records. Choice D ('No one owns a medical record') is incorrect as medical records are owned by healthcare providers who create and maintain them, such as physicians.
