Final answer:
The client might (gain/lose) weight as a result of taking a beta blocker and should be monitored for: Gain (Option A). This is due to a potential slowdown in metabolism. Monitoring for weight gain is recommended. It is important to differentiate between the effects of medications on weight and conditions such as hyperthyroidism and hypothyroidism that can influence it.
Step-by-step explanation:
The question at hand involves the effects of beta-blockers on weight. Beta-blockers are medications commonly prescribed for cardiovascular conditions, and one of their side effects can be a weight change.
The client might gain weight as a result of taking a beta blocker and thus monitoring for weight gain is advisable, making the answer (A) Gain.
This is because beta blockers can slow down metabolism and reduce the body's ability to burn calories effectively.
Patients with hyperthyroidism, like Patient B who shows signs of weight loss and increased heart rate, might see a reversal of these symptoms upon taking beta blockers, as they can temper the overactive thyroid function.
Another condition, hypothyroidism, is known to result in symptoms like weight gain, cold sensitivity, and reduced mental activity, but this condition is not typically treated with beta-blockers.
It's important to differentiate the effect of medications on weight from conditions that naturally bring about weight change.
Hence, the correct answer is Option A. Gain.
