Correct Answer: B

Rationale: The correct answer is B: PTT (Partial Thromboplastin Time) because it specifically measures the effectiveness of heparin therapy by assessing the intrinsic pathway of the coagulation cascade. A prolonged PTT indicates that heparin is achieving the desired anticoagulant effect. A: INR (International Normalized Ratio) is used to monitor warfarin therapy, not heparin. C: PT (Prothrombin Time) is also used to monitor warfarin therapy. D: Bleeding time is not typically used to monitor heparin therapy and is more focused on platelet function rather than coagulation factors.

Rationale: The correct answer is A. Waiting for the patient to complete the sentence is the most appropriate intervention as it allows the patient time to formulate their thoughts and express themselves. It shows patience and respect for the patient's communication process. B: Immediately showing objects may overwhelm the patient and not allow them to express their thoughts fully. C: Leaving the room would not address the patient's communication difficulty and could make them feel abandoned or misunderstood. D: Naming objects for the patient assumes what they are trying to say and may not accurately represent their intended message.

Rationale: The correct answer is B: Develop good communication skills. In interdisciplinary collaboration, effective communication is essential for teamwork. By developing good communication skills, the nurse can effectively interact with other healthcare professionals to provide holistic care. Choice A is incorrect as the nurse should collaborate as part of a team, not necessarily be the leader. Choice C is incorrect as interdisciplinary collaboration involves working with professionals from various disciplines. Choice D is incorrect as conflict resolution is an important aspect of effective collaboration.

Correct Answer: D

Rationale: The correct answer is D: Decrease the intake of trace elements and antioxidant supplements. Clients with HIV/AIDS do not require additional trace elements and antioxidant supplements, as excessive intake can be harmful. HIV/AIDS already places stress on the immune system, so taking excessive supplements may lead to toxicity. It is important to focus on a balanced diet rich in essential nutrients rather than overloading the body with unnecessary supplements. Encouraging a healthy, balanced diet will help support overall health and immune function in clients with HIV/AIDS. Choices A, B, and C are incorrect because encouraging excessive intake of fat-soluble vitamins, water-soluble vitamins, iron, and zinc can also lead to potential adverse effects. It is important to focus on meeting the recommended daily allowances for these nutrients rather than exceeding them.

Correct Answer: A

Rationale: The correct answer is A because auscultation of the lungs involves direct observation and measurement, making it objective data. This data is based on what the nurse hears through the stethoscope, which can be verified and measured. Choices B, C, and D involve subjective experiences or interpretations that cannot be directly observed or measured. Complaint of nausea, sensation of burning, and belief in demons are all based on the client's feelings, perceptions, or beliefs, which are subjective and can vary from person to person. Objective data is factual, measurable, and observable, making choice A the correct answer in this scenario.
