Correct Answer: B

Rationale: The correct answer is B: inadequate supply of oxygen to the myocardium. Angina pectoris is chest pain or discomfort caused by reduced blood flow to the heart muscle. This lack of oxygenated blood supply to the myocardium leads to ischemia, resulting in the characteristic chest pain. Choice A is incorrect as it refers to a decrease in alveolar surface area for gas exchange, which is related to conditions like emphysema, not angina. Choice C is incorrect as it pertains to pulmonary circulation, not coronary circulation. Choice D is incorrect as an increase in alveolar surface area would not be a cause of angina pectoris.

Correct Answer: D

Rationale: The correct answer is D, "Eliminate background noise." This technique is essential for older patients as they may have age-related hearing impairments. By reducing background noise, the patient can better focus on the information being conveyed. Sitting in bright sunlight (A) may cause glare and make it difficult to read or see clearly. Speaking in a high tone (B) may be perceived as aggressive or patronizing. Using small, white-on-black printed materials (C) may be challenging for older patients with visual impairments. Thus, eliminating background noise is the most effective technique to improve learning in preoperative older patients.

Correct Answer: B

Rationale: Correct Answer: B: Calcium should be avoided Rationale: 1. Calcium is an essential mineral for bone health, especially important for individuals with limited mobility like Richard. 2. Avoiding calcium can lead to bone weakening and increase the risk of fractures. 3. Nursing care plans should include adequate calcium intake to support bone health. 4. Therefore, avoiding calcium is not a recommended nutritional consideration. Summary of Incorrect Choices: A: The diet should be semisolid to facilitate the passage of food - This is important for individuals with swallowing difficulties. C: The patient should be sitting in an upright position during feeding - This aids in proper digestion and reduces the risk of aspiration. D: Thick fluids should be encouraged to provide additional calories - Thick fluids may increase the risk of aspiration in patients with neurological conditions.

Correct Answer: B

Rationale: The correct answer is B because administration of the diuretic furosemide without saline is not recommended for managing hypercalcemia. Furosemide can lead to volume depletion and potentially exacerbate hypercalcemia by concentrating calcium levels in the blood. A: Fluid administration helps dilute calcium levels by increasing urine output. C: Inorganic phosphate salts can bind with calcium in the gut, reducing absorption. D: Intravenous phosphate therapy can help lower calcium levels by promoting calcium-phosphate complex formation. In summary, B is incorrect as it may worsen hypercalcemia, while A, C, and D are valid strategies for managing hypercalcemia.

Correct Answer: C

Rationale: The correct answer is C because washing feet in hot water can lead to burns or skin damage for those with diabetes. A: Proper footwear is essential for preventing foot injuries. B: Trimming toenails straight across helps prevent ingrown nails. D: Wearing shoes on hot surfaces prevents burns or blisters. Overall, C is incorrect due to the potential harm it can cause to diabetic feet.
