Correct Answer: A

Rationale: A testicular examination is appropriate for a 20-year-old male to screen for testicular cancer, which is more common in younger age groups. Testicular cancer is most frequently diagnosed in individuals between the ages of 15 and 40. Blood glucose screening is typically recommended for older individuals or those at risk for diabetes. Fecal occult blood testing is used for colorectal cancer screening, usually starting at age 50. Prostate-specific antigen testing is commonly considered for prostate cancer screening in older males, typically around age 50. Therefore, the most appropriate screening for the 20-year-old client is the testicular examination.

Correct Answer: C

Rationale: The correct answer is C. It is an ethical dilemma when the family of a client with a terminal illness asks healthcare providers not to inform the client of their diagnosis. This situation poses a conflict between respecting the client's right to know the truth about their condition (autonomy and truth-telling principles) and honoring the family's wishes. Choices A, B, and D do not present ethical dilemmas. Choice A involves professional accountability and responsibility, Choice B involves a client's personal preference, and Choice D involves financial challenges.

Correct Answer: A

Rationale: The correct answer is A: Knowledge. In this scenario, the healthcare professional is utilizing knowledge by gathering and applying information about the medication. Choice B, Experience, is not the best option as the focus is on accessing information about the medication rather than personal experience. Choice C, Intuition, refers to a gut feeling or instinct, which is not evident in the scenario. Choice D, Competence, relates more to overall ability and proficiency rather than the specific act of seeking information.

Correct Answer: B

Rationale: When assessing a young adult's musculoskeletal system, the nurse should expect an exaggerated lumbar curvature (lordosis). This is a normal finding in young adults due to the natural curvature of the spine. Concave thoracic spine posteriorly (choice A) and concave lumbar spine posteriorly (choice C) are not typical findings as the spine should have normal curvatures. Exaggerated thoracic curvature (choice D) is also not a typical finding in young adults.

Correct Answer: A

Rationale: The correct answer is A. Washing out the feeding bag once every 24 hours with warm water can lead to bacterial growth due to inadequate cleaning, potentially causing diarrhea. Hot water, as in choice B, can also promote bacterial growth, which is not desirable. Changing the feeding bag every 48 hours, like in choice C, is within an acceptable timeframe and is unlikely to be a cause of diarrhea. Adding water to the formula before administration, as in choice D, is a common practice to dilute the formula but is not typically associated with causing diarrhea in this scenario.
