Correct Answer: A

Rationale: The proper hand position for chest percussion is to cup the hands, creating a hollow space to allow for effective transmission of percussion vibrations. Cupping the hands helps to produce the desired percussion sound and ensures proper force distribution. Using the side of the hands (B) may not provide enough surface area for effective percussion. Flattening the hands (C) may not generate the desired percussive effect, and spreading the fingers of both hands (D) can result in uneven force application. Therefore, cupping the hands is the most appropriate hand position for chest percussion.

Correct Answer: A

Rationale: The correct answer is A: coma. High ammonia levels can lead to hepatic encephalopathy, causing impaired brain function and potentially leading to coma. Edema (B) is typically associated with fluid retention, not high ammonia levels. Hypoxia (C) is a condition of low oxygen levels, not directly related to high ammonia levels. Polyuria (D) is excessive urination, which is not a common sign of high ammonia levels.

Correct Answer: B

Rationale: Mammography is used to detect tumors in the breast tissue. It is a screening tool for breast cancer. Tumors can be either benign or malignant. Mammograms help in early detection of abnormalities in breast tissue. Pain, edema, and epilepsy are unrelated to the purpose of mammography. Pain is a symptom, edema is swelling, and epilepsy is a neurological disorder. Therefore, the correct answer is B because mammography is specifically designed to detect tumors in the breast.

Correct Answer: D

Rationale: Step-by-step rationale for why answer D is correct: 1. Empathy and respect: By saying "I respect your decision to choose surgery," you acknowledge her autonomy and decision-making. 2. Supportive approach: This response shows understanding and non-judgmental support for her choice. 3. Person-centered care: Recognizing her individual needs and choices is crucial in providing quality healthcare. Summary: A: Irrelevant and insensitive to her medical needs. B: Disregards her current situation and overlooks the complexity of weight loss. C: Implies a one-size-fits-all approach without considering her specific circumstances. D: Demonstrates respect, understanding, and support for her decision-making.

Correct Answer: A

Rationale: Step 1: Stop the transfusion - Febrile reaction can indicate a transfusion reaction, so stopping the transfusion is crucial. Step 2: Administer antipyretics - To reduce fever and prevent further complications. Step 3: Assess for other signs of transfusion reaction - Such as chills, rash, or hypotension. Summary: Option A is correct as it addresses the immediate need to stop the transfusion and manage the fever. Options B, C, and D do not prioritize stopping the transfusion, which is crucial in this scenario.
