Correct Answer: B

Rationale: The correct answer is B: Phenytoin (Dilantin). Phenytoin is known to cause gingival hyperplasia as a side effect, which can be minimized with good oral hygiene practices. Procainamide, Azathioprine, and Allopurinol are not associated with gingival hyperplasia. Therefore, the client receiving cyclosporine should focus on practicing good oral hygiene specifically when taking Phenytoin to minimize the risk of developing gingival hyperplasia.

Correct Answer: D

Rationale: The correct answer is D: Improve ability to hear. A hearing aid is designed to improve a person's ability to hear by amplifying sound. This helps individuals with hearing loss to better understand speech and sounds in their environment. A: Amplifying background noise is not the main purpose of a hearing aid. It may actually hinder the user's ability to focus on important sounds. B: Amplifying musical sounds is not the primary function of a hearing aid. The main focus is on improving speech understanding. C: Occluding the ear is not the purpose of a hearing aid. It is meant to enhance hearing, not block sound.

Correct Answer: A

Rationale: The correct answer is A: Administering an oral dose of levothyroxine (Synthroid). In myxedema coma, there is severe hypothyroidism leading to altered mental status, hypothermia, and organ failure. Administering levothyroxine is crucial to replace the deficient thyroid hormone rapidly and restore metabolic function. Warming the client (B) is important but secondary to addressing the underlying hormonal imbalance. Measuring intake and output (C) is essential for overall assessment but not the most critical intervention. Maintaining a patent airway (D) is always important in any medical emergency but does not directly address the primary issue of hypothyroidism in myxedema coma.

Correct Answer: B

Rationale: The correct answer is B: Use pressure relieving devices when the client is in bed. This is because pressure ulcers are a common risk for individuals with neuromuscular disorders due to immobility. Pressure relieving devices such as special mattresses or cushions help redistribute pressure and prevent skin breakdown. Incorrect choices: A: Preventing strenuous exercises is not directly related to preventing skin breakdown in this case. C: Placing the client in Fowler's position may be beneficial for respiratory issues but does not directly address skin integrity. D: Avoiding daily baths with soaps may lead to poor hygiene and does not specifically address the risk of skin breakdown.

Correct Answer: A

Rationale: The correct answer is A: Preventing infection. With a low WBC count of 3,000/ul, the client is at high risk for infection due to compromised immune function. Priority is to prevent infection by implementing strict infection control measures, such as hand hygiene, sterile techniques, and isolation precautions. Alleviating pain (B) would be important but not the priority in this case. Controlling infection (C) is similar to preventing infection and would be a secondary intervention. Monitoring blood transfusion reactions (D) is not relevant to the client's current lab values.
