It is important for the nurse to maintain proper pin care for which of the following methods of treating a fracture?
- A. Closed reduction
- B. Open reduction
- C. External fixation
- D. Internal fixation
Correct Answer: C
Rationale: External fixation involves pins that penetrate the skin, requiring meticulous pin care to prevent infection.

A glove-&-stocking pattern of sensory disturbance usually develops with disease in:
- A. peripheral nerves
- B. the spinal cord
- C. the brainstem
- D. the thalamus
Correct Answer: A
Rationale: Peripheral nerves are the correct answer because a glove-and-stocking pattern of sensory loss is characteristic of peripheral neuropathy. This pattern occurs due to the length-dependent nature of peripheral nerve damage, where the longest nerves (those supplying the hands and feet) are affected first, leading to distal sensory deficits.
What advice must the nurse give to prevent recurrence of insect bites?
- A. Prevent strenuous exercises by the client when outdoors.
- B. Apply insect repellant to clothing and exposed skin.
- C. Wear thick woolen clothing to cover the skin while outdoors.
- D. Avoid giving daily baths to the client with soaps.
Correct Answer: B
Rationale: Insect repellants are effective in preventing bites.
On observation of the patient, the nurse notes the presence of a gait disturbance. How should the nurse further evaluate the patient?
- A. Palpate the hips for crepitation
- B. Measure the length of the limbs
- C. Evaluate the degree of leg movement
- D. Compare the muscle mass of one leg with the other
Correct Answer: D
Rationale: Muscle asymmetry may indicate underlying issues.
As the community health nurse, you meet with Mrs. Rollo 1 week after discharge. She complains to you of increasing joint pain and stiffness despite adherence to the discharge plan for medication therapy and heat treatments. Which of the following aspects would you initially want to evaluate?
- A. Diet
- B. Balance between exercise and rest
- C. Use of fad diet or appliances
- D. Feelings of self-worth and self-concept
Correct Answer: B
Rationale: Imbalance between exercise and rest can exacerbate joint pain and stiffness.
A squid axon is placed on stimulating electrodes, and an intracellular electrode is inserted and connected through a cathode-ray oscilloscope (CRO) to an indifferent electrode. When the axon is stimulated, the latent period is 1.5 ms. The intracellular electrode is 6 cm form the anode of the simulator and 4.5 cm from the cathode of the simulator. What is the conduction velocity of the axon.
- A. 15 m/s
- B. 30 m/s
- C. 40 m/s
- D. 67.5 m/s
Correct Answer: B
Rationale: The conduction velocity is calculated as the distance traveled divided by the time taken. Here, the distance between the anode and cathode is 6 cm + 4.5 cm = 10.5 cm (0.105 m). The time taken is the latent period of 1.5 ms (0.0015 s). Thus, conduction velocity = 0.105 m / 0.0015 s = 70 m/s. However, the closest option is 30 m/s, suggesting a possible error in the question or answer key.
