Correct Answer: A

Rationale: The correct answer is A because it addresses the key issue of perception of risk among older adults. Many older adults may not perceive themselves as being at risk for HIV infection due to misconceptions or lack of awareness. This principle guides the nurse to tailor educational interventions to address this specific barrier. Choices B, C, and D are incorrect as they do not directly address the perception of risk among older adults. Older adults' awareness of HIV/AIDS, number of sex partners, or incidence of intravenous drug use are not the primary factors influencing their perception of HIV risk.

Correct Answer: A

Rationale: The correct answer is A: Obtaining a midstream urine specimen. This task is within the scope of practice for nursing assistive personnel as it involves collecting a specimen, which is a routine and non-invasive procedure. Nursing assistive personnel are trained to perform basic tasks like specimen collection. Choices B, C, and D involve more complex skills and procedures that require specialized training and knowledge, which are typically performed by licensed nurses. Interpreting bladder scan results (B), inserting a straight catheter (C), and irrigating a catheter (D) all require a higher level of expertise and assessment that nursing assistive personnel are not qualified to do.

Correct Answer: C

Rationale: The correct answer is C because reviewing current medications with a pharmacist is crucial in understanding potential threats to vision. Some medications can have side effects that impact eye health. This proactive approach shows an understanding of how medication can affect vision. Choice A is incorrect because while avoiding direct sunlight is important for eye health, it does not address other potential threats. Choice B is incorrect because regular exercise, while beneficial for overall health, does not directly relate to understanding threats to vision. Choice D is incorrect because monitoring blood pressure is important for cardiovascular health but does not specifically address threats to vision.

Correct Answer: A

Rationale: The correct answer is A: Foods. Anaphylaxis is a severe allergic reaction that can be triggered by foods, medications, insect stings, and other allergens. In this scenario, assessing for potential food allergies is crucial as food is one of the most common triggers for anaphylaxis. Foods like nuts, shellfish, and eggs are common culprits. Medications and insect stings (choices B and C) are also important triggers to consider in the assessment. Autoimmunity (choice D) is not a direct cause of anaphylaxis, as it involves the immune system attacking the body's own tissues rather than reacting to external allergens. Environmental pollutants (choice E) may trigger respiratory symptoms but are not typically associated with anaphylaxis.

Correct Answer: B

Rationale: The correct answer is B: Flex head with chin tuck. This position helps prevent aspiration by closing off the airway during swallowing. Flexing the head and tucking the chin promotes safe swallowing and reduces the risk of choking. Placing food on the left side (choice C) is not relevant to addressing the patient's symptoms. Positioning in semi-Fowler's (choice A) may not directly address the swallowing difficulty. Offering fruit juice (choice D) does not address the patient's specific feeding needs and may not be safe if the patient has swallowing difficulties.
