Correct Answer: A

Rationale: The correct answer is A. Consistently following the same order when drawing up different insulins helps to prevent medication errors. Option B is incorrect because shaking insulin vials could cause bubbles to form, leading to inaccurate dosing. Option C is incorrect as insulin should be stored in the refrigerator, not the freezer, to maintain its effectiveness. Option D is incorrect because cloudy appearance in intermediate-acting insulin may indicate the presence of insulin crystals, which can affect its potency, but this does not necessarily mean it should be discarded without consulting a healthcare provider.

Correct Answer: A

Rationale: Administering intravenous fluids is the priority in treating DKA for several reasons. DKA is characterized by severe dehydration and electrolyte imbalances due to hyperglycemia. IV fluids help to correct dehydration, restore electrolyte balance, and decrease blood glucose levels. Administering oral glucose (Choice B) would be contraindicated in DKA as the primary issue is high blood glucose levels. Administering a fever-reducing medication (Choice C) is not the priority in managing DKA. Administering oxygen therapy (Choice D) may be necessary in some cases, but correcting dehydration and electrolyte imbalances take precedence in the management of DKA.

Correct Answer: A

Rationale: When a client experiences secondary failure to an oral antidiabetic agent like glipizide, the next step is often to initiate insulin therapy. This is because secondary failure indicates that the current oral antidiabetic medication is no longer effective in managing blood glucose levels, and insulin therapy may be required to adequately control blood sugar. Switching to a different oral antidiabetic agent may not be effective if there is already resistance to the current agent. Adding another oral antidiabetic agent may not address the underlying issue of secondary failure. Restricting carbohydrate intake is important for diabetes management but is not the primary intervention indicated in this scenario of secondary failure to glipizide.

Correct Answer: B

Rationale: The correct answer is 'Business sense.' Nurse managers need to understand how financial decisions impact patient outcomes, which requires a strong understanding of business principles. Leadership (choice A) is important but doesn't specifically address understanding financial and outcome-based impacts. Clinical expertise (choice C) is essential for patient care but doesn't directly relate to understanding budget changes and their impact. Financial management (choice D) is more about managing finances directly rather than understanding the broader implications of budget changes on patient outcomes.

Correct Answer: A

Rationale: Diabetes insipidus is a condition characterized by a deficiency of antidiuretic hormone (ADH). ADH plays a crucial role in regulating water balance by controlling the amount of water reabsorbed by the kidneys. Options B, C, and D are incorrect as they are not associated with diabetes insipidus. TSH (thyroid-stimulating hormone) is responsible for regulating thyroid function, while FSH (follicle-stimulating hormone) and LH (luteinizing hormone) are involved in reproductive functions.
