Correct Answer: D

Rationale: The correct answer is D because the presence of a physical characteristic like a scar is an objective finding that can be directly observed and measured during a physical assessment. This information is not subject to interpretation or bias. In contrast, choices A, B, and C involve subjective information that relies on the patient's report or memory, making them less reliable and objective. History of allergies (A) and use of medications (B) are subjective and based on the patient's self-report, while last menstrual period (C) is also subjective and may not always be accurate. Therefore, choice D is the only objective piece of information among the options provided.

Correct Answer: A

Rationale: The correct answer is A: Palpation. Palpation involves using the hands to touch and feel the skin to assess its temperature accurately. This technique allows the nurse to detect variations in temperature more effectively compared to visual inspection (Choice C) or listening with a stethoscope (Choice B). Using a thermometer (Choice D) may also provide a precise measurement, but palpation allows for a more comprehensive assessment of skin temperature by considering factors such as localized warmth or coolness.

Correct Answer: B

Rationale: The correct answer is B: Be totally honest with him, even if the information is unpleasant. This is the best approach because honesty builds trust and credibility, crucial in a healthcare setting. It allows the teenager to make informed decisions about his care and fosters a therapeutic relationship. Explanation for why the other choices are incorrect: A: Using periods of silence may be misinterpreted as indifference or lack of engagement. C: Promising total confidentiality may not be feasible in healthcare settings and could lead to potential harm if critical information needs to be shared with others for the patient's safety. D: Using slang language may come across as unprofessional and may hinder effective communication and understanding between the nurse and the patient.

Correct Answer: C

Rationale: Rationale: Choice C is correct as additional questions in a review of systems for a 76-year-old patient should address age-related changes. This allows for better assessment of potential health issues specific to older adults. Choice A is incorrect as questions may vary based on age. Choice B is incorrect as age alone does not dictate question changes. Choice D is incorrect as a review of systems is important at all ages for comprehensive patient assessment.

Correct Answer: A

Rationale: The correct answer is A: Severe headaches and blurred vision. Hypertension can lead to complications such as hypertensive crisis, causing symptoms like severe headaches and blurred vision due to increased pressure in the blood vessels. This can indicate a serious health issue requiring immediate medical attention. Weight loss and dizziness (B), increased appetite and tremors (C), and nausea and vomiting (D) are not typically associated with hypertension complications. It's crucial for the nurse to educate the patient on recognizing these signs to prevent further health risks.
