Correct Answer: D

Rationale: The correct answer is D. In Addison's disease, the adrenal glands do not produce enough cortisol and aldosterone. This leads to sodium and potassium imbalances. Low aldosterone causes sodium loss and potassium retention, resulting in sodium and potassium abnormalities. The other choices, A, B, and C, do not directly relate to Addison's disease. Calcium and phosphorus abnormalities are not typically associated with Addison's disease. Sodium and chloride, and chloride and magnesium imbalances are not primary concerns in Addison's disease. Therefore, staying alert for signs and symptoms of sodium and potassium abnormalities is crucial in managing and monitoring a client with Addison's disease.

Correct Answer: C

Rationale: Step-by-step rationale: 1. Propranolol is a beta-blocker that acts on the heart. 2. It blocks beta-adrenergic receptors, leading to decreased heart rate and contractility. 3. Decreased heart rate and contractility result in reduced cardiac output. 4. Therefore, the correct answer is C - It decreases cardiac output. Summary: A, B, and D are incorrect because propranolol does not increase heart rate, fluid volume, or cardiac contractility.

Correct Answer: D

Rationale: The correct answer is D: Sitting up leaning slightly forward. This position helps prevent blood from flowing back into the throat, reducing the risk of choking and aspiration. It also allows for better drainage of blood out of the nose. Lying down with feet elevated (choice A) can increase blood flow to the head and worsen the nosebleed. Sitting up with neck extended (choice B) can lead to blood flowing into the throat. Lying down with a small pillow under the head (choice C) may cause blood to flow backward.

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.
