Correct Answer: C

Rationale: Correct Answer: The correct answer is C, 'Hyperkalemia.' Sodium polystyrene sulfonate (Kayexalate) is a medication used to treat high potassium levels (hyperkalemia) by exchanging sodium ions for potassium ions in the intestines, leading to potassium removal from the body. Therefore, the nurse should monitor the client for changes in potassium levels to assess the effectiveness of the medication and prevent potential complications related to hyperkalemia. Choice A, 'Hyponatremia,' is incorrect as Kayexalate does not primarily affect sodium levels. Choice B, 'Hypokalemia,' is incorrect as Kayexalate is used to treat high potassium levels, not low. Choice D, 'Hypocalcemia,' is incorrect as Kayexalate does not directly impact calcium levels.

Correct Answer: A

Rationale: The correct answer is A: Fortified milk and cereals. Osteomalacia is a condition caused by a deficiency in vitamin D. Fortified milk and cereals are rich sources of vitamin D, which is essential for managing osteomalacia. Citrus fruits and juices (choice B) are high in vitamin C, but vitamin D is the primary concern for osteomalacia. Green leafy vegetables (choice C) are good sources of various nutrients but not the main focus for managing osteomalacia. Red meats and eggs (choice D) are good sources of protein and other nutrients but are not as critical as fortified milk and cereals for addressing vitamin D deficiency in osteomalacia.

Correct Answer: C

Rationale: In chronic pancreatitis, managing abdominal pain is crucial, and assessing the client's eating patterns and dietary intake is essential. Dietary modifications can help alleviate symptoms and reduce the workload on the pancreas. Choices A, B, and D are not directly related to pain management in chronic pancreatitis. Bowel sounds, fecal characteristics, and physical activity may provide important information in other conditions but are not the priority in this scenario.

Correct Answer: C

Rationale: The correct answer is to instruct the client on how to take deep breaths. Deep breathing exercises are essential in preventing postoperative respiratory complications like atelectasis by promoting lung expansion. Using incentive spirometry is a more specific and advanced method of promoting deep breathing and lung expansion, making it a better choice than just turning in bed. While turning in bed may help with overall comfort and positioning, it is not as directly related to respiratory complications as deep breathing exercises. Coughing, although important for clearing secretions, is not as effective in preventing atelectasis as deep breathing exercises.
