Correct Answer: A

Rationale: The correct answer is A because measuring oxygen saturation will provide objective data to assess the client's respiratory status accurately. This step is crucial in identifying the severity of the client's breathing difficulty and determining the appropriate intervention. Encouraging deep breathing exercises (B) may worsen the client's condition if there is an underlying respiratory problem. Simply documenting the client's statement (C) without immediate action can delay necessary interventions. Providing oxygen without further assessment (D) can be harmful if the client's oxygen saturation is already high. Overall, option A is the most appropriate as it involves a proactive and evidence-based approach to address the client's reported breathing difficulty.

Correct Answer: C

Rationale: The correct answer is C because respirations of 16 are measurable and quantifiable, making them objective data. Subjective data, like choices A, B, and D, are based on the patient's feelings or experiences and cannot be measured or observed directly. Choice A is subjective as it relies on the patient's self-report. Choice B is subjective as it describes a symptom reported by the patient. Choice D is subjective as it reflects the patient's feeling of nausea. Objective data is essential for making accurate clinical assessments and decisions.

Correct Answer: C

Rationale: Objective data are measurable and observable facts obtained through physical examination or diagnostic tests. In this case, "Respirations 16" is a quantifiable and observable measurement, making it objective data. It is not influenced by personal interpretation or feelings. The other choices, such as "States 'doesn't feel good'", "Reports a headache", and "Nauseated" are subjective data because they are based on the patient's feelings or experiences, which can vary depending on individual perception and interpretation, making them less reliable for making clinical decisions. By focusing on objective data like "Respirations 16", the nurse can provide a more accurate assessment of the patient's condition.

Correct Answer: C

Rationale: The correct answer is C: Cooked vegetables. Cooking vegetables helps to kill harmful bacteria and parasites that may pose a risk of infection to an immunocompromised individual like a patient with HIV. Raw fruits (A) and raw vegetables (B) may carry pathogens that can be dangerous for someone with a weakened immune system. Caesar dressing (D) may contain raw eggs, which also pose a risk for infection. Therefore, choosing cooked vegetables is the safest option to reduce the risk of infection for the patient with HIV.

Correct Answer: B

Rationale: Step-by-step rationale: 1. Corticotropin-secreting pituitary adenoma leads to excess adrenocorticotropic hormone (ACTH) production. 2. High corticotropin levels would be expected due to the adenoma's overproduction. 3. The high cortisol levels occur as a result of increased ACTH stimulating cortisol release from the adrenal glands. 4. Therefore, choice B (high corticotropin and high cortisol levels) is the correct answer. Summary: - Choice A is incorrect because low cortisol levels would not be expected in a client with a corticotrophin-secreting pituitary adenoma. - Choice C is incorrect because low corticotropin levels would not align with the excessive ACTH production from the adenoma. - Choice D is incorrect as both low corticotropin and low cortisol levels would not be consistent with the pathophysiology of a corticotrophin-secreting pituitary adenoma.
