Correct Answer: C

Rationale: Objective data in nursing refers to measurable and observable information. Respirations at 16 per minute are a specific, quantifiable measurement that the nurse can directly observe, making it objective data. This information is vital for assessing the patient's respiratory status accurately. Choice A is incorrect because stating "doesn't feel good" is a subjective statement based on the patient's perception and cannot be directly measured or observed. Choice B, reporting a headache, is also subjective as it relies on the patient's description of their symptoms. Choice D, being nauseated, is subjective as well, as it is a symptom reported by the patient and not a quantifiable measurement. In summary, choice C is correct as it represents objective data due to its quantifiable and observable nature, while the other choices are subjective and based on the patient's perceptions or feelings.

Correct Answer: C

Rationale: Rationale: Choice C is the correct answer because following safer-sex practices is crucial in preventing the spread of HIV/AIDS. By emphasizing this point, the nurse can educate clients on reducing the risk of transmission. Safer-sex practices include using condoms and practicing monogamy. Choice A is incorrect because avoiding recreational drugs and alcohol, while important for overall health, is not directly related to preventing the spread of HIV/AIDS. Choice B is incorrect as it is essential for individuals to inform their sexual partners about their HIV status to prevent transmission and ensure informed consent. Choice D is incorrect because while it may be required by law in some places, it is not the most crucial point for preventing the spread of HIV/AIDS within a support group setting.

Correct Answer: C

Rationale: Objective data are measurable and observable facts. Respirations (C) of 16 per minute is objective data as it is a quantifiable measurement that can be counted and recorded. It is not influenced by personal interpretation or bias. Choices A, B, and D are subjective data as they rely on the patient's feelings, perceptions, or symptoms, which can vary and are open to interpretation. Therefore, choice C is the correct answer as it represents concrete, verifiable information that can be used in the patient's assessment and care planning.

Correct Answer: A

Rationale: The correct answer is A: Anemia. Anemia is a common condition characterized by a decrease in red blood cells or hemoglobin levels, leading to symptoms like fatigue and weakness. It is often suspected based on symptoms such as pale skin and shortness of breath. Rheumatic arthritis (B) is a type of arthritis affecting joints, not related to the blood. Leukemia (C) is a type of cancer affecting the blood and bone marrow. Systemic Lupus Erythematosus (SLE) (D) is an autoimmune disease that can affect various organs, not specifically related to blood cell levels. Therefore, based on the symptoms described, anemia is the most likely condition to be suspected.

Correct Answer: A

Rationale: The correct answer is A. In the Snellen eye chart test, the first number (20) represents the distance at which the client is viewing the chart, and the second number (40) represents the distance at which a person with normal vision can read the same line. Therefore, a client with 20/40 vision sees letters at 20 feet that others with normal vision can read at 40 feet. Choices B, C, and D are incorrect because they do not accurately reflect the interpretation of the 20/40 vision result from the Snellen eye chart test. B is incorrect because the client does not see letters at 40 feet that others can read at 20 feet. Choices C and D are incorrect because the Snellen eye chart test measures visual acuity, not color perception.
