Correct Answer: A

Rationale: The correct answer is A: Monitor aPTT levels. This is crucial in intravenous heparin therapy to ensure the therapeutic range is maintained for anticoagulation without causing bleeding. Monitoring aPTT helps adjust heparin dosage to prevent clot formation or excessive bleeding. B: Monitoring for bleeding is important but not the most important action compared to monitoring aPTT levels for appropriate dosing. C: Checking platelet count is important for some anticoagulants like heparin, but aPTT monitoring is more directly related to heparin's anticoagulant effect. D: Administering a heparin antidote (protamine sulfate) is necessary in case of heparin overdose or in emergency situations but is not the primary action in routine care.

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: 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: The correct answer is A: Assess vital signs. This is the first intervention because it provides immediate information on the client's condition and helps determine the severity of the pain. Monitoring vital signs can reveal signs of shock, dehydration, or other serious complications. Performing a CT scan (B) is not the first priority as it requires time and resources. Monitoring urine output (C) may be important but not as immediate as assessing vital signs. Monitoring for signs of shock (D) can be included in assessing vital signs but is not the primary intervention.

Correct Answer: A

Rationale: The correct answer is A: Administer bronchodilators. During an acute asthma attack, the priority intervention is to immediately open the airways to improve breathing. Bronchodilators, such as albuterol, work rapidly to dilate the bronchioles and relieve bronchospasms, making it the most effective initial treatment. Corticosteroids (B) are used for long-term control, not immediate relief. Applying oxygen and administering albuterol (C) is close, but bronchodilators should be given first for quicker relief. Applying a cold compress (D) is not appropriate for managing an asthma attack.
