Correct Answer: C

Rationale: The correct answer is C: liver function tests. Isoniazid and Rifampicin are known to potentially cause hepatotoxicity, leading to abnormal liver function test results. Liver function tests measure enzymes and proteins that indicate liver health. Gallbladder studies (A), thyroid function tests (B), and blood sugar levels (D) are not directly affected by these medications and would not show abnormal results due to their use.

Correct Answer: A

Rationale: The correct answer is A because educating young adults about the rise in heterosexual transmission of HIV is crucial to prevent the spread of AIDS. This information helps them understand the importance of safe sex practices and awareness of risks. Choice B is incorrect as HIV transmission in children is not primarily due to sexual abuse. Choice C is also incorrect as herpes zoster is not a form of the HIV virus. Choice D is incorrect as transmission by IV drug users is not prominent with sterile equipment use. Focusing on the rise in heterosexual transmission is key in teaching young adults about AIDS prevention.

Correct Answer: B

Rationale: The correct answer is B: Discuss the negative feelings with the client. This is the most appropriate action as it allows the nurse to address and manage their own biases and attitudes towards the client in a professional and constructive manner. By acknowledging and discussing these feelings with the client, the nurse can work towards providing non-judgmental care and fostering a therapeutic relationship. A: Sharing these feelings with the client is not appropriate as it can harm the nurse-client relationship and potentially lead to discrimination. C: Developing a written interview form is not addressing the immediate issue of the nurse's negative attitude towards the client. D: Avoiding eye contact with the client is unprofessional and does not address the underlying issue of the nurse's negative feelings.

Correct Answer: D

Rationale: The correct answer is D: Hypocalcemia. Severe diarrhea can lead to electrolyte imbalances, including low calcium levels. Decreased muscle tone and deep tendon reflexes are classic signs of hypocalcemia. Calcium is essential for proper muscle function and nerve transmission. Hypernatremia (A) is high sodium levels, not related to decreased muscle tone. Hyperchloremia (B) is high chloride levels, not associated with muscle tone changes. Hypokalemia (C) is low potassium levels, which can cause muscle weakness but not specifically decreased muscle tone and deep tendon reflexes like hypocalcemia.

Correct Answer: C

Rationale: Rationale: Choice C is the correct answer because drinking lots of water at night actually helps prevent UTIs by flushing out bacteria from the urinary tract. Holding the urge to urinate (Choice A) can increase the risk of UTIs as bacteria can multiply in stagnant urine. Insertion of instruments and catheters (Choice B) can introduce bacteria, leading to infection. Unhygienic cleaning after defecation (Choice D) can also introduce bacteria to the urinary tract, causing UTIs. Therefore, Choice C is the exception as it does not contribute to the common causes of UTIs.
