Correct Answer: D

Rationale: The correct answer is D, Arcus senilis. This condition does not cause visual problems in the older adult. Arcus senilis is a grayish-white ring around the cornea, which does not affect vision. Glaucoma, macular degeneration, and cataracts are conditions that can lead to visual impairment in older adults. Glaucoma is characterized by increased pressure in the eye, which can damage the optic nerve and lead to vision loss. Macular degeneration affects the central part of the retina, leading to blurred or distorted vision. Cataracts cause clouding of the lens, resulting in decreased vision. Therefore, Arcus senilis is the correct choice as it does not cause visual problems compared to the other conditions listed.

Correct Answer: D

Rationale: The correct answer is D because asking the patient about their usual sleep patterns and onset of difficulty resting is crucial to understand the situation fully. This helps to identify any potential underlying issues contributing to the sleep disturbance. Choice A is incorrect as it dismisses the patient's concerns. Choice B is not as effective as directly addressing the patient's sleep issues. Choice C delays the assessment, potentially missing important information. By choosing answer D, the nurse can gather valuable information to address the patient's sleep problem effectively.

Correct Answer: D

Rationale: The correct answer is D because using multiple drugs for tuberculosis reduces the development of resistant strains of the bacteria. When multiple drugs are used simultaneously, it decreases the likelihood of the bacteria developing resistance to any single drug. This approach helps to ensure that the treatment remains effective over time. Explanation for other choices: A: While using multiple drugs may allow for reduced dosages, the primary rationale is not solely to administer lower levels of drugs. B: Although using multiple drugs may help in managing side effects, the primary rationale is to prevent the development of resistant strains. C: While multiple drugs may have a synergistic effect, the main purpose is to prevent resistance rather than potentiate the action of individual drugs.

Correct Answer: D

Rationale: The correct answer is D: anesthesiologist. The anesthesiologist is responsible for transferring the patient to the PACU as they are in charge of the patient's anesthesia management throughout the surgery. They are trained to assess the patient's condition post-surgery, manage any immediate postoperative complications, and ensure a smooth transition to the PACU staff for continued care. The circulating nurse (A) is responsible for managing the operating room environment, the scrub nurse (B) assists the surgeon during the surgery by passing instruments, and the surgeon (C) performs the surgical procedure but does not typically transfer the patient to the PACU.

Correct Answer: A

Rationale: Step-by-step rationale for why answer A is correct: 1. Assessing respiratory status is crucial during a choking incident to identify if the resident is unable to breathe. 2. In this scenario, the resident's inability to breathe indicates a life-threatening problem requiring immediate intervention. 3. CPR is initiated based on the assessment of the resident's breathing difficulty, emphasizing the critical nature of identifying a life-threatening issue. 4. The assessment of respiratory status directly informs the nurse's actions to address the immediate danger of choking. Summary: - Choice A is correct as assessing respiratory status helps identify life-threatening issues like choking. - Choice B is incorrect as the primary focus is on immediate intervention, not establishing a database. - Choice C is incorrect as the assessment is not for skill practice but for identifying a critical situation. - Choice D is incorrect as the goal is not to facilitate breathing but to address the immediate life-threatening problem.
