Correct Answer: A

Rationale: The correct answer is A: Blood urea nitrogen (BUN). In CKD, the kidneys are unable to effectively filter waste products, leading to an increase in BUN levels. Elevated BUN indicates impaired kidney function. Calcium, potassium, and sodium levels may also be affected in CKD, but they are more likely to be imbalanced rather than consistently elevated. Calcium levels may be low due to impaired vitamin D activation, potassium levels may be high due to decreased excretion, and sodium levels can fluctuate based on fluid status. Therefore, while these lab values may be abnormal in CKD, BUN is the most consistently elevated marker of kidney dysfunction.

Correct Answer: A

Rationale: The correct answer is A: Blood pressure measurement. Dizziness and weakness can be symptoms of hypotension or low blood pressure. Prioritizing blood pressure measurement is crucial because it can indicate if the patient is at risk of complications like cardiovascular collapse. Pulse oximetry (B) is important for assessing oxygen levels in the blood but may not directly address dizziness and weakness. Blood glucose levels (C) are important but not the priority in this scenario. Cardiac monitoring (D) may be necessary but should come after assessing blood pressure to rule out immediate life-threatening conditions.

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: Administer oxygen. Oxygenation is the priority in stroke management to ensure adequate oxygen supply to the brain. Oxygen therapy can help reduce hypoxia, which is crucial in the acute phase of a stroke. Administering aspirin (B) is important but comes after ensuring oxygenation. Administering thrombolytics (C) requires proper assessment and diagnostic confirmation, not an immediate priority. Placing the client in a supine position (D) may worsen stroke symptoms if there is compromised blood flow, so it is not recommended as the initial action.

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.
