Correct Answer: A

Rationale: The correct answer is A: Inspect for visible pulsation. This is because an arteriovenous fistula for hemodialysis should have a visible pulsation, indicating proper blood flow. Palpating for thrill (B) and auscultating for bruit (C) are also common assessments for an arteriovenous fistula, but inspecting for visible pulsation is the most direct and reliable way to assess the patency of the fistula. Percussing for dullness (D) is not relevant in this context as it does not provide information about the vascular access site.

Correct Answer: B

Rationale: The correct answer is B because the mental health examination should be integrated into the health history interview. This allows for a comprehensive understanding of the patient's mental health status. Gathering mental health information during the health history interview is crucial as it provides insight into the patient's current mental state, past history, and potential risk factors. This integrated approach is efficient and effective in assessing the patient's mental health needs. A is incorrect because while family input can be valuable, it is not always the best or only resource for information about coping skills. C is incorrect as integrating the mental health examination into the health history interview should not necessarily take an enormous amount of extra time if done efficiently. D is incorrect as a complete mental health examination may not always be necessary to assess the patient's level of functioning; integrating mental health information into the health history interview can often provide sufficient insight.

Correct Answer: B

Rationale: The correct answer is B: Monitor INR levels. INR (International Normalized Ratio) is a crucial parameter to monitor for clients on anticoagulant therapy, as it measures the effectiveness of the medication in preventing blood clots. By monitoring INR levels, the nurse can ensure the client is within the therapeutic range to prevent both bleeding and clotting complications. Choice A (Monitor platelet count) is incorrect because anticoagulant therapy does not directly affect platelet count, and monitoring platelets is more relevant for clients on antiplatelet therapy. Choice C (Monitor bleeding) is partially correct, but focusing solely on monitoring bleeding may not provide a comprehensive assessment of the client's response to anticoagulant therapy. Choice D (Monitor renal function) is incorrect as anticoagulant therapy primarily affects coagulation factors and not renal function. Renal function monitoring may be necessary for certain medications but is not a primary consideration for anticoagulant therapy.

Correct Answer: A

Rationale: The correct answer is A: Encouraging early ambulation to prevent deep vein thrombosis. Early ambulation helps prevent blood clot formation in the legs, reducing the risk of deep vein thrombosis post-surgery. It also promotes circulation and aids in preventing complications like pneumonia. Administering pain medication (B) is important, but preventing complications should take priority. Providing wound care (C) is essential but not the top priority. Encouraging a high-protein diet (D) is beneficial for healing, but immediate post-operative mobility is crucial for preventing complications.

Correct Answer: A

Rationale: The correct answer is A: Administer oxygen. ARDS is characterized by severe hypoxemia, and oxygen therapy is essential to improve oxygenation. Administering corticosteroids (B) is not recommended as they do not improve outcomes in ARDS. Monitoring serum glucose (C) is unrelated to the treatment of ARDS. Administering pain relief (D) is important for patient comfort but does not address the underlying hypoxemia in ARDS. Oxygen therapy is the primary treatment to support respiratory function and improve oxygen delivery in ARDS.
