Choice A reason: Leave the pad in place for at least 40 minutes

Leaving the aquathermia pad in place for at least 40 minutes is not recommended. The typical duration for applying an aquathermia pad is 20 to 40 minutes1. Prolonged exposure beyond this time can lead to complications such as burns or vasoconstriction, where blood vessels constrict instead of dilate, potentially increasing blood pressure and causing discomfort.

Choice B reason: Set the pad’s temperature to 42.2°C (108°F)

Setting the pad’s temperature to 42.2°C (108°F) is too high. The recommended temperature range for an aquathermia pad is generally between 40.5°C to 43°C (105°F to 109.4°F)3. Temperatures above this range can increase the risk of burns and skin damage. It is crucial to follow the manufacturer’s guidelines and institutional protocols to ensure safe and effective use of the pad.

Choice C reason: Use safety pins to keep the pad in place

Using safety pins to keep the pad in place is not safe. Safety pins can puncture the pad, causing leaks and potentially leading to electrical hazards. Instead, the pad should be secured with tape or a cloth cover to ensure it stays in place without causing damage.

Choice D reason: Stop the treatment if the client’s skin becomes red

Stopping the treatment if the client’s skin becomes red is the correct action. Redness of the skin can indicate the beginning of a burn or other skin damage. It is essential to monitor the client’s skin condition frequently during the application of heat therapy and to discontinue the treatment immediately if any signs of adverse reactions, such as redness or discomfort, are observed.

Choice A Reason:

Constipation is not typically associated with hyperthyroidism. Hyperthyroidism usually speeds up the body’s metabolism, leading to symptoms like increased bowel movements or diarrhea rather than constipation.

Choice B Reason:

Sensitivity to cold is more commonly associated with hypothyroidism, where the body’s metabolism slows down. In hyperthyroidism, patients often experience heat intolerance due to an increased metabolic rate.

Choice C Reason:

Weight gain of 4.5 kg (10 lbs) in 3 weeks is also more indicative of hypothyroidism. Hyperthyroidism generally causes weight loss despite an increased appetite because of the accelerated metabolism.

Choice D Reason:

Frequent mood changes are a common symptom of hyperthyroidism. The excess thyroid hormones can affect the nervous system, leading to symptoms such as anxiety, irritability, and mood swings.
