Correct Answer: B

Rationale: The correct answer is B: Collect his urine for 12 hours. This instruction is given because the Schilling test involves collecting urine over a specific time period to measure the absorption of vitamin B12. A is incorrect because fasting is not necessary. C is incorrect as enema is not required. D is incorrect as emptying the bladder is not part of the test procedure.

Correct Answer: C

Rationale: The correct answer is C: limit daily alcohol intake. This is crucial for clients with cirrhosis as alcohol can exacerbate liver damage. Limiting alcohol intake helps prevent further harm to the liver and promotes overall health. Supplementation with multivitamins (choice A) can be beneficial, but not as essential as avoiding alcohol. Taking sleeping pills (choice B) may worsen liver function and is not recommended. Limiting contact at all times (choice D) is irrelevant to managing cirrhosis.

Correct Answer: A

Rationale: The correct answer is A: Inform the physician immediately. This is important because finding a lump in the breast could be a sign of breast cancer, so prompt medical evaluation is crucial. Checking after the next menstrual cycle (B) may delay diagnosis and treatment. Squeezing the nipple (C) can cause harm and is not a reliable method for assessing a lump. Using a heating pad (D) is not recommended as it may mask symptoms and delay proper evaluation. Early detection and intervention are key in improving outcomes for breast cancer.

Correct Answer: B

Rationale: The correct answer is B: “Rotate injection sites within the same anatomic region, not among different regions.” This instruction is important to prevent lipodystrophy and ensure consistent insulin absorption. Rotating sites within the same region helps maintain consistent insulin absorption rates and reduces the risk of developing scar tissue or fatty deposits. Injecting into healthy tissue with large blood vessels and nerves (choice A) can lead to inconsistent absorption. Administering insulin into areas of scar tissue or hypotrophy (choice C) can also disrupt absorption. Injecting into sites above muscles planned for exercise (choice D) can lead to unpredictable insulin absorption. Rotation within the same region optimizes insulin delivery and prevents complications.

Correct Answer: C

Rationale: The correct answer is C. Wearing protective gear such as gown, mask, gloves, and goggles when entering the room is crucial to prevent infection in patients with AIDS. This intervention helps to minimize the risk of transmitting pathogens to the patient and vice versa. The protective gear acts as a barrier to prevent the spread of infectious agents. It also protects healthcare workers from exposure to potentially harmful pathogens. Prohibiting visitors who are severely immunodeficient (choice A) may be isolating for the patient and does not directly address preventing infection transmission. Prohibiting visitors with a cough (choice B) is important but does not cover all potential sources of infection. Ensuring protective barrier isolation precautions are in place (choice D) is a general statement and does not specify the practical steps needed to prevent infection transmission effectively.
