Correct Answer: C

Rationale: The correct answer is C: deposits of adipose tissue in the trunk and dorsocervical area. In Cushing's syndrome, there is excess cortisol production leading to central obesity with fat accumulation in the trunk and dorsocervical area (buffalo hump). This is due to cortisol's role in redistributing fat. A: hypotension is incorrect because individuals with Cushing's syndrome typically have hypertension due to the effects of excess cortisol on blood pressure regulation. B: thick, coarse skin is incorrect as individuals with Cushing's syndrome may have thin, fragile skin due to decreased collagen formation. D: weight gain in arms and legs is incorrect as the weight gain in Cushing's syndrome tends to be centralized in the trunk and face rather than the extremities.

Correct Answer: B

Rationale: The correct answer is B: Apply insect repellent to clothing and exposed skin. This advice helps prevent insect bites, reducing the risk of recurrence. Insect repellent creates a barrier against insects, hence minimizing the chances of getting bitten. Other choices are incorrect as they do not directly address the prevention of insect bites. Choice A is vague and does not provide a specific preventive measure. Choice C is incorrect as thick woollen clothing may not necessarily prevent insect bites. Choice D, sunscreen lotion, protects against UV rays, not insect bites.

Correct Answer: A

Rationale: The correct answer is A: Etiology. Etiology in a nursing diagnosis refers to the cause or contributing factors of the identified problem. In this case, the large scar over the left side of the face is the reason for the disturbed self-esteem. It is the underlying factor that is leading to the self-esteem issue. The problem itself is the disturbed self-esteem, the defining characteristics are the signs and symptoms that support the diagnosis, and client need is the desired outcome or goal for the client. In summary, the presence of the large scar is the cause or etiology of the disturbed self-esteem, making it the correct choice.

Correct Answer: C

Rationale: The correct answer is C: Close the roller clamp on the new tubing after priming it. This step ensures that the tubing is primed with the solution and ready for use while preventing air from entering the central line. Option A is incorrect because using the present solution may introduce contamination. Option B is incorrect as connecting tubing before running fluid can introduce air into the line. Option D is incorrect as positioning the client on the right side does not prevent air embolism during tubing change.

Correct Answer: B

Rationale: The correct answer is B: Do not give the antibiotic. This is because the patient has a history of being "very sick" after taking erythromycin in the past, indicating a potential allergic reaction or severe adverse effects. The nurse should not administer the antibiotic to prevent harm to the patient. Choice A is incorrect as it can lead to a repeat adverse reaction. Choice C, giving half the dose, still exposes the patient to potential harm. Choice D, discontinuing the antibiotic, is also incorrect as it implies the patient has already started the medication, which should not be the case given the history of adverse effects.
