Correct Answer: C

Rationale: The correct answer is C: 'Hypokalemia.' Furosemide is a loop diuretic that can lead to potassium depletion (hypokalemia) due to increased urinary excretion of potassium. This can result in adverse effects such as muscle weakness, cardiac dysrhythmias, and other complications. Hyperkalemia (choice A) is not an adverse effect of furosemide but rather an elevated potassium level. Hyperglycemia (choice B) and hyponatremia (choice D) are not typically associated with furosemide use. Therefore, monitoring potassium levels and addressing hypokalemia is crucial in clients taking furosemide.

Correct Answer: A

Rationale: Corrected Rationale: The correct answer is A, left upper quadrant pain. In acute pancreatitis, inflammation of the pancreas commonly causes pain in the left upper quadrant of the abdomen. This pain can be severe and radiate to the back. Periumbilical pain (choice B) is more indicative of acute appendicitis. Rebound tenderness (choice C) is associated with peritoneal inflammation, not specifically pancreatitis. Flank pain (choice D) is more characteristic of conditions involving the kidneys or ureters, such as renal colic.

Correct Answer: B

Rationale: The correct answer is B. Increasing folic acid intake is crucial during pregnancy to prevent neural tube defects. Option A is incorrect because calorie requirements during pregnancy vary and are generally higher than 1,200 calories per day. Option C is not specific to pregnancy nutrition teaching, although hydration is important. Option D is incorrect as iron-rich foods are typically recommended during pregnancy to prevent anemia.

Correct Answer: C

Rationale: In acute pancreatitis, the gastrointestinal tract needs to rest to reduce pancreatic enzyme secretion. Inserting a nasogastric tube for suction helps decompress the stomach and reduce stimulation of the pancreas. Encouraging oral intake of clear liquids (Choice A) or administering an antiemetic before meals (Choice B) may aggravate the condition by stimulating the pancreas. Placing the client in a supine position (Choice D) may not directly address the underlying issue of reducing pancreatic stimulation.

Correct Answer: C

Rationale: The correct answer is C: Thyroid-stimulating hormone (TSH). Monitoring TSH levels is crucial to assess the effectiveness of levothyroxine in clients with hypothyroidism. TSH is produced by the pituitary gland and stimulates the thyroid gland to produce thyroid hormones. In hypothyroidism, where the thyroid gland is underactive, administering levothyroxine helps to normalize thyroid hormone levels. Monitoring TSH levels allows the healthcare provider to adjust the levothyroxine dosage to ensure that thyroid hormone levels are within the therapeutic range. Choices A, B, and D (Calcium, Sodium, and Magnesium) are not directly related to assessing the effectiveness of levothyroxine therapy in hypothyroidism and would not provide relevant information regarding the medication's efficacy.
