Correct Answer: D

Rationale: The correct answer is D: The patient has been infected with HIV. Antibodies to the AIDS virus in the blood indicate a past or current infection with HIV. This is because the body produces antibodies in response to the presence of the virus. A: The patient is immune to HIV is incorrect because antibodies indicate exposure, not immunity. B: The patient's immune system is intact is incorrect because the presence of antibodies does not necessarily reflect the overall functionality of the immune system. C: The patient has AIDS-related complications is incorrect because the presence of antibodies does not directly indicate the presence of AIDS-related complications.

Correct Answer: A

Rationale: The correct answer is A: A patient with infection taking tetracycline with milk. This is because tetracycline binds with the calcium in milk, reducing its absorption and effectiveness. The nurse should follow up to ensure the patient is not compromising the treatment. Choices B and C are incorrect because increasing fiber for irritable bowel syndrome and following a high-fiber diet for diverticulitis are appropriate interventions that do not require immediate follow-up. Choice D is incorrect because it is a routine part of managing enteral feedings to monitor gastric residuals, and does not necessarily require immediate follow-up unless there are specific concerns.

Correct Answer: C

Rationale: Correct Answer: C Rationale: 1. Exostoses are bony growths in the external auditory canal. 2. These growths can cause narrowing and obstruction of the canal, affecting hearing. 3. Collaborating with the pharmacist to assess for ototoxic medications is crucial to prevent further hearing impairment. 4. Performing Rinne and Weber tests (choice A) and arranging audiometry testing (choice B) are not directly related to exostoses. 5. Ignoring exostoses (choice D) can lead to worsening hearing loss and potential complications.

Correct Answer: A

Rationale: The correct answer is A: Blowing up balloons. Blowing up balloons involves the activation of the facial muscles, which helps prevent muscle atrophy in patients with Bell's palsy. This exercise promotes muscle strength and prevents weakness. Deliberately frowning (B), smiling repeatedly (C), and whistling (D) do not specifically target the facial muscles involved in Bell's palsy and may not be as effective in preventing muscle atrophy.

Correct Answer: D

Rationale: The correct answer is D: Different molecular structure in the cells. Malignant cells have alterations in their molecular structure, leading to uncontrolled growth and invasion of surrounding tissues, while benign cells retain their normal molecular structure and do not invade nearby tissues. This distinction is crucial in understanding why malignant cells are cancerous and pose a greater risk compared to benign cells. Other choices are incorrect because: A: Slow rate of mitosis of cancer cells - Malignant cells actually have a rapid rate of mitosis, contributing to their uncontrolled growth. B: Different proteins in the cell membrane - While there may be differences in proteins, the molecular structure is a more fundamental difference between malignant and benign cells. C: Differing size of the cells - Cell size alone is not a definitive characteristic that distinguishes between malignant and benign cells; molecular structure plays a more significant role.
