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: A

Rationale: The correct answer is A because a poultice of sodium bicarbonate and water can help neutralize the venom and reduce pain from wasp and bee bites. Sodium bicarbonate has alkaline properties that can counteract the acidic venom. Option B is incorrect as household ammonia can cause skin irritation and should not be applied to insect bites. Option C is incorrect because only option A is a safe and effective treatment for wasp and bee bites. Option D is incorrect as there is a suitable emergency treatment available.

Correct Answer: C

Rationale: The correct answer is C: 3, 4, 2005. HIV can be transmitted through breast milk, blood, and semen due to the presence of the virus in these bodily fluids. Saliva, tears, and other body fluids do not typically contain enough of the virus to transmit HIV. Therefore, choices A, B, and D are incorrect as they include saliva, tears, and other non-transmissible fluids. It is crucial for the nurse to educate the patient on the modes of transmission to prevent the spread of HIV.

Correct Answer: B

Rationale: The correct answer is B: Ask the patient to describe the type of reaction. This is the first action the nurse should take to assess the severity of the latex allergy and determine appropriate interventions. By gathering more information about the reaction, the nurse can better understand the potential risks and provide safe care. Summary of other choices: A: Immediately placing the patient in isolation is unnecessary and not indicated based solely on the patient's latex allergy. C: Proceeding to the termination phase of the interview is premature without fully assessing the patient's allergy. D: Documenting the allergy is important but should not be the first action without assessing the reaction itself.

Correct Answer: D

Rationale: The correct answer is D: avoid caffeine, alcohol, and chocolate. This helps to reduce acid reflux symptoms associated with hiatal hernia. Caffeine, alcohol, and chocolate can relax the lower esophageal sphincter, leading to increased reflux. Elevating legs (choice A) does not address the underlying issue. Drinking more fluids (choice B) can exacerbate symptoms by increasing stomach volume. Increasing roughage (choice C) may worsen symptoms due to increased gastric distension. By avoiding triggers like caffeine, alcohol, and chocolate, the client can effectively manage her symptoms.
