After teaching a group of students about changes in body weight due to aging, the instructor determines that the students have understood the teaching when they state which of the following?
Thinning of the vertebral discs leads to weight loss.
An increase in lean body mass leads to weight gain.
Spinal kyphosis contributes to the increase in body weight.
Loss of muscle tissue contributes to the decrease in weight.
The Correct Answer is D
A. Thinning of the vertebral discs leads to a decrease in height, not weight.
B. Lean body mass actually decreases with aging, contributing to weight loss rather than gain.
C. Spinal kyphosis affects posture but does not significantly contribute to changes in body weight.
D. Loss of muscle tissue (sarcopenia) is correct because aging leads to a decline in muscle mass, which contributes to weight loss. Additionally, a slower metabolism and reduced physical activity further affect body composition.

Correct Answer is C
Explanation
A. Documenting bradycardia is incorrect because the client is experiencing tachycardia (HR 108), not bradycardia.
B. Applying oxygen at 2L/min is incorrect because the oxygen saturation is normal (96% on room air). Oxygen therapy is not indicated at this time.
C. Reassess the vital signs in five minutes is correct because the slightly elevated heart rate and respiratory rate may be due to recent physical activity after prolonged bedrest. It is important to allow the client time to recover and reassess before taking further action.
D. Notifying the provider is incorrect because there is no immediate concern; the elevated HR and RR are expected post-activity.
Correct Answer is A
Explanation
A. Inflating the blood pressure cuff 30 mmHg above the point where the radial pulse disappears is correct. This method, known as the palpatory method, prevents auscultatory gap errors and ensures an accurate blood pressure reading.
B. Assisting the patient to a standing position for five to ten minutes is incorrect unless assessing for orthostatic hypotension. For routine blood pressure measurements, the client should be seated and at rest for at least five minutes.
C. Palpating the radial artery and placing the stethoscope lightly over this area is incorrect because blood pressure is auscultated over the brachial artery, not the radial artery.
D. Measuring the blood pressure cuff to encircle 60% of the client’s arm is incorrect. The correct guideline is that the cuff bladder should encircle at least 80% of the arm circumference, not 60%.
