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.

Correct Answer: B

Rationale: The correct instruction is to rinse the mouth after each use of a corticosteroid inhaler to prevent oral candidiasis (thrush). Choice A is incorrect because corticosteroid inhalers are usually used on a regular schedule to control asthma symptoms, not just for acute symptoms. Choice C is incorrect as corticosteroid inhalers are typically used for long-term management, not just during asthma attacks. Choice D is incorrect as administering a bronchodilator after using a corticosteroid is not a standard practice and is not necessary for the effectiveness of the corticosteroid inhaler.

Correct Answer: B

Rationale: Methimazole is the correct answer. It is commonly used to manage hyperthyroidism by inhibiting the production of thyroid hormones. Levothyroxine (Choice A) is actually a medication used to treat hypothyroidism by supplementing thyroid hormones. Propylthiouracil (Choice C) is another anti-thyroid medication used in the management of hyperthyroidism. Prednisone (Choice D) is a corticosteroid and is not typically used in the treatment of hyperthyroidism.

Correct Answer: A

Rationale: The correct answer is to administer IV fluids. This intervention is the priority as it helps rapidly restore hydration in patients with dehydration by delivering fluids directly into the bloodstream. Monitoring intake and output (choice B) is important but comes after providing immediate fluid resuscitation. Administering oral fluids (choice C) may not be sufficient for a patient with dehydration who requires rapid rehydration. Providing electrolyte replacement (choice D) is essential but often follows fluid resuscitation to correct any electrolyte imbalances resulting from dehydration.

Correct Answer: A

Rationale: In patients with heart failure, monitoring daily weight is the most accurate method for assessing fluid balance. Weight gain can indicate fluid retention, a common issue in heart failure patients. Monitoring input and output (B) is essential but may not always accurately reflect fluid balance. Checking for edema (C) is important as it can indicate fluid accumulation, but daily weight monitoring is more precise. Monitoring blood pressure (D) is important in heart failure management but does not directly assess fluid balance.
