Correct Answer: D

Rationale: Step 1: Providing referral to support groups and resources for information is essential for HIV positive clients as it offers emotional support, education, and access to resources for managing the condition. Step 2: Support groups provide a safe space for clients to share experiences, seek advice, and reduce feelings of isolation. Step 3: Resources for information help clients stay informed about their condition, treatment options, and lifestyle modifications. Step 4: Referral to support groups and resources promotes holistic care and enhances the client's overall well-being. Summary: Choices A, B, and C are incorrect as they do not address the specific needs of HIV positive clients and may even pose risks to their health. Option D is the most appropriate intervention as it focuses on comprehensive support and empowerment for clients.

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: C

Rationale: Step 1: Hyponatremia is an electrolyte imbalance characterized by low sodium levels in the blood. Step 2: Restricting fluid intake helps prevent further dilution of sodium in the blood, aiding in correcting hyponatremia. Step 3: Administering sodium can lead to rapid correction, risking osmotic demyelination syndrome. Step 4: Choice C is correct as it aligns with the goal of managing hyponatremia by preventing fluid overload symptoms. Summary: A, B, and D are incorrect as they do not directly address the primary concern of correcting low sodium levels in hyponatremia.

Correct Answer: C

Rationale: The correct answer is C: severe, unrelieved pain. Compartment syndrome is characterized by increased pressure within a muscle compartment leading to decreased blood flow and tissue damage. Severe, unrelieved pain is a hallmark sign as the pressure builds up. Weak movement of the patient's toes (choice A) could indicate nerve damage but is not specific to compartment syndrome. Decreased pedal pulses (choice B) could suggest vascular compromise but are not specific to compartment syndrome. Presence of foot pallor (choice D) could indicate poor circulation but is not a definitive sign of compartment syndrome.

Correct Answer: C

Rationale: The correct answer is C because mastitis typically presents with swollen, firm, and hard breasts due to inflammation and infection of the breast tissue. This occurs as a result of milk stasis and bacterial infection. Option A is incorrect because a crack in the nipple or areola can be indicative of nipple trauma or infection, not necessarily mastitis. Option B is incorrect because multiple lumps within the breast tissue may suggest fibrocystic changes or breast cancer, but not specifically mastitis. Option D is incorrect because enlargement of the axillary lymph nodes is more commonly seen in breast cancer, not mastitis.
