A nurse is reinforcing teaching with a client who has an ankle injury and requires crutches. Which of the following instructions should the nurse provide?

"Maintain your head and neck erect when walking with crutches."

"Keep your elbows flexed at a 35° angle when using the crutches."

"Support your body weight by leaning on the crutches."

“Wash the tips of your crutches daily."

Answer and Explanation

The Correct Answer is B

A. "Maintain your head and neck erect when walking with crutches.": This is incorrect. The focus should be on posture and the use of crutches, not just the head and neck. Maintaining an erect posture is essential, but this option is too narrow and doesn’t provide full guidance on proper crutch use.

B. "Keep your elbows flexed at a 35° angle when using the crutches.": This is correct. The elbows should be slightly bent, approximately at a 30- to 35-degree angle, to ensure proper use of the crutches. This position prevents excessive strain on the shoulders and wrists while providing effective support.

C. "Support your body weight by leaning on the crutches.": This is incorrect. The crutches should not bear the entire weight of the body. Instead, the weight should be distributed through the arms and hands with the crutches supporting some of the load. Leaning on the crutches can lead to nerve damage or further injury.

D. “Wash the tips of your crutches daily.": This is incorrect. While it is important to keep crutches clean, washing the tips daily is unnecessary. It is more important to check the crutches for wear and tear and ensure the rubber tips are intact and provide proper traction.

Correct Answer is D

Explanation

A. Positive clonus is a sign of hyperreflexia and can indicate worsening preeclampsia or severe central nervous system irritability. It is not a therapeutic effect of magnesium sulfate.

B. Urinary output 20 mL/hr is below the minimum expected urine output (which is generally 30 mL/hr). This finding suggests oliguria and may be a sign of worsening renal function, which is not a therapeutic effect of magnesium sulfate.

C. Respiratory rate 10/min is too low. Magnesium sulfate can cause respiratory depression, and a respiratory rate of 10/min may indicate toxicity. This is not a therapeutic effect.

D. Deep tendon reflexes 2+ is the correct answer. Magnesium sulfate is used to prevent seizures in preeclampsia by acting as a CNS depressant.
