Correct Answer: C

Rationale: The correct answer is C because respirations of 16 is an observable and measurable data point that can be quantified. Objective data are factual, measurable, and based on observable phenomena. In contrast, choices A, B, and D are subjective data as they rely on the patient's feelings or experiences, which are not directly measurable or observable by the nurse. Reporting a headache or feeling nauseated are subjective symptoms that are based on the patient's perception and cannot be verified without further assessment. Therefore, only choice C provides objective data that can be accurately reported by the nurse.

Correct Answer: C

Rationale: The correct answer is C because the American Cancer Society recommends women to have a mammogram annually starting at age 45, then have the option to transition to biennial screening at age 55. This recommendation is based on evidence that regular mammograms can help detect breast cancer early, increasing chances of successful treatment. Choice A is incorrect because self-examinations are no longer recommended as a routine screening method. Choice B is incorrect as clinical breast exams are not as effective as mammograms for detecting breast cancer. Choice D is incorrect as normal receptor assays are not part of routine breast cancer screening guidelines.

Correct Answer: B

Rationale: Correct Answer: B (State Nurse Practice Acts) Rationale: State Nurse Practice Acts outline the legal scope of nursing practice, including standards for setting priorities, identifying client outcomes, and selecting evidence-based nursing interventions. These laws are specific to nursing practice, ensuring that nurses follow guidelines tailored to their profession. Nurses must adhere to these standards to provide safe and effective care. Summary of Incorrect Choices: A: Professional physicians' organizations - While physicians' organizations may provide guidelines for medical practice, they do not set standards specific to nursing practice. C: The Joint Commission - The Joint Commission focuses on accreditation for healthcare organizations, not setting standards for nursing practice. D: The Agency for Health Care Research and Quality - AHRQ conducts research and provides evidence-based information but does not establish standards for nursing practice.

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: 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.
