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: C

Rationale: The correct answer is C: 'Decreased urine output.' Syndrome of inappropriate antidiuretic hormone (SIADH) is characterized by excessive release of antidiuretic hormone, leading to water retention and decreased urine output. Therefore, the nurse should expect the client to have decreased urine output. Choices A, B, and D are incorrect. Hypernatremia (Choice A) is not typically associated with SIADH as it usually leads to dilutional hyponatremia. Hypotension (Choice B) is not a common clinical manifestation of SIADH. Polyuria (Choice D) is the opposite of what is expected in a client with SIADH, who typically presents with decreased urine output.

Correct Answer: C

Rationale: In an Addisonian crisis, there is a lack of adrenal hormones leading to severe hypotension. Hypertension (choice A) is not a typical sign of Addisonian crisis but can occur in conditions like pheochromocytoma. Hyperglycemia (choice B) is not a characteristic sign of an Addisonian crisis. Tachycardia (choice D) may occur as a compensatory mechanism in response to hypotension, but severe bradycardia is more common in an Addisonian crisis.

Correct Answer: B

Rationale: When a patient like Albert refuses his bedtime snack, it can lead to hypoglycemia, especially if they are on medication such as insulin. Hypoglycemia can occur earlier than expected due to the lack of carbohydrate intake before bedtime. This situation warrants the healthcare provider to monitor for signs and symptoms of hypoglycemia. Choice A is incorrect because the given scenario is more indicative of hypoglycemia than metabolic alkalosis. Choice C is incorrect as NPH insulin peak time is not directly related to skipping a bedtime snack. Choice D is incorrect as sugar in the urine typically indicates hyperglycemia, not hypoglycemia.

Correct Answer: C

Rationale: Tachycardia is a potential adverse effect of levothyroxine, indicating overmedication. Dysuria (painful urination) is not typically associated with levothyroxine. Leg cramps are not a common adverse effect of levothyroxine. Blurred vision is not a typical adverse effect of levothyroxine; instead, it may be a sign of other eye-related conditions or medication side effects.
