Sample Questions and Explanations

To give you a sense of what to expect, here are sample questions similar to those you might encounter in the PN Learning System Medical-Surgical Musculoskeletal Practice Quiz, along with detailed explanations.

Question 1: A patient is admitted with a fractured femur. Which nursing intervention is the most important in the immediate post-injury period?

A) Encouraging active range of motion exercises.

B) Applying ice to the affected area.

C) Administering pain medication.

D) Assessing neurovascular status.

Answer: D) Assessing neurovascular status.

Explanation: In the immediate post-injury period, assessing neurovascular status (circulation, sensation, and movement) is the priority. A fractured femur can compromise blood supply and nerve function in the affected limb.

Question 2: A patient with rheumatoid arthritis (RA) reports increased joint pain and stiffness, especially in the morning. Which of the following recommendations is most appropriate?

A) Encourage the patient to remain inactive to rest the joints.

B) Advise the patient to perform high-impact exercises to strengthen the muscles around the joints.

C) Suggest the patient take a hot bath in the morning to relieve stiffness.

D) Recommend the patient take nonsteroidal anti-inflammatory drugs (NSAIDs) on an empty stomach.

Answer: C) Suggest the patient take a hot bath in the morning to relieve stiffness.

Explanation: Warmth can help relieve stiffness and pain associated with RA. Hot baths, warm compresses, or showers can be beneficial, particularly in the morning.

Question 3: Which of the following is a major risk factor for osteoporosis?

A) Obesity.

B) High calcium intake.

C) Sedentary lifestyle.

D) Regular weight-bearing exercise.

Answer: C) Sedentary lifestyle.

Explanation: A sedentary lifestyle is a major risk factor for osteoporosis because weight-bearing exercise is essential for maintaining bone density.

Question 4: A patient reports pain and numbness in the hand, especially at night. The symptoms are consistent with carpal tunnel syndrome. Which assessment finding would further support this diagnosis?

A) Positive Babinski sign.

B) Positive Trousseau's sign.

C) Positive Phalen's test.

D) Positive Romberg test.

Answer: C) Positive Phalen's test.

Explanation: Phalen's test involves holding the wrists in flexion for 60 seconds. A positive test (reproduction of symptoms) is indicative of carpal tunnel syndrome.

Question 5: A patient is recovering from a total hip arthroplasty (THA). Which instruction should the nurse emphasize to prevent hip dislocation?

A) Adducting the legs while sitting.

B) Bending at the waist to pick up objects.

C) Using an abduction pillow while in bed.

D) Crossing the legs while lying down.

Answer: C) Using an abduction pillow while in bed.

Explanation: An abduction pillow keeps the legs separated, preventing hip adduction, which can lead to dislocation after THA.
