Which of the following best describes Chvostek's sign assessment?

Assessing a client's blood pressure using a sphygmomanometer.

Assessing a client's muscle contractions by tapping on the facial nerve.

Assessing a client's heart rate using a stethoscope.

Assessing a client's respiratory rate using a pulse oximeter.

Answer and Explanation

The Correct Answer is B

A. Assessing blood pressure with a sphygmomanometer is unrelated to Chvostek's sign, which specifically evaluates neuromuscular excitability.
B. Chvostek's sign is assessed by tapping the facial nerve near the cheekbone. A positive response, such as twitching of the facial muscles, indicates hypocalcemia or neuromuscular irritability.
C. Assessing heart rate with a stethoscope does not involve evaluating neuromuscular function or calcium levels.
D. Monitoring respiratory rate with a pulse oximeter is unrelated to Chvostek's sign and does not assess neuromuscular excitability.

Correct Answer is C

Explanation

A. This describes a transverse fracture, where the bone breaks completely across and perpendicular to the shaft. It does not describe a greenstick fracture.
B. A spiral fracture is caused by a twisting force, which results in a helical break. This is not a greenstick fracture.
C. A greenstick fracture occurs when the bone bends and cracks on the outer arc but does not break completely through. This type of fracture is more common in children because their bones are softer and more flexible.
D. This describes a comminuted fracture, where the bone breaks into several pieces. It does not match the description of a greenstick fracture.

A. Encourage the client to change positions B. Encourage the client to exercise vigorously C. Encourage the client to stand for extended periods D. Encourage the client to limit fluid intake

Correct Answer is A

Explanation

A. Encouraging the client to change positions slowly, such as moving from lying to sitting and then to standing, helps to minimize the risk of orthostatic hypotension. This gradual change allows the body to adjust to positional changes without causing a sudden drop in blood pressure.
B. Encouraging vigorous exercise is not recommended for a client with hypovolemia as it could exacerbate the condition, potentially causing dizziness, fainting, or further lowering blood pressure.
C. Encouraging the client to stand for extended periods is not appropriate for a client at risk for orthostatic hypotension, as standing for prolonged periods can cause blood to pool in the lower extremities, increasing the risk of fainting or dizziness.
D. Encouraging the client to limit fluid intake is inappropriate for a client with hypovolemia. Adequate fluid intake is crucial to help restore blood volume and prevent hypotension.
