Correct Answer: A

Rationale: Administering oxygen is crucial for a patient presenting with confusion after surgery because it helps alleviate potential hypoxia, which can be a common cause of confusion in the postoperative period. While repositioning the patient, administering IV fluids, and performing a neurological assessment are important nursing interventions in certain situations, addressing hypoxia by administering oxygen takes priority in this case to ensure an adequate oxygen supply to the brain and other vital organs.

Correct Answer: A

Rationale: Polyuria is the excessive production of urine and is a common finding in clients with hyperglycemia due to increased glucose levels. High blood sugar levels lead to the body trying to eliminate the excess glucose through urine, resulting in increased urination. Hypoglycemia (choice B) is low blood sugar and is not typically associated with hyperglycemia. Diaphoresis (choice C) is excessive sweating and is not a direct symptom of hyperglycemia. Tachycardia (choice D) is increased heart rate and is not a primary finding in hyperglycemia.

Correct Answer: A

Rationale: The correct answer is A: Check the central line site daily. Monitoring the central line site daily is crucial in detecting early signs of infection, such as redness, swelling, tenderness, or drainage. By checking the site regularly, healthcare providers can take prompt action to prevent complications. Choice B, monitoring the patient's vital signs, while important in assessing overall health, may not specifically indicate an infection related to the central line. Choice C, checking the central line dressing every other day, may not be frequent enough to catch early signs of infection. Choice D, checking for signs of sepsis, is important but represents a more severe stage of infection and may occur after local signs at the central line site have already manifested.

Correct Answer: A

Rationale: Verifying the patient's identity is a critical step when administering a blood transfusion to ensure that the correct blood product is given to the right patient. This process helps prevent errors and enhances patient safety. Choice B, 'Administer medication,' is incorrect because the focus during a blood transfusion should be on ensuring the correct blood product is administered. Choice C, 'Monitor vital signs,' is also important but comes after verifying the patient's identity. Choice D, 'Start blood transfusion without verification,' is incorrect and unsafe as patient identification verification is essential prior to starting any medical procedure, especially one as important as a blood transfusion.
