1. Ceroid pigments and lipofuscin accumulate with aging, impairing a cell's ability to withstand the damaging effects of oxygen free radicals.

Correct answer: True

Rationale: The statement provided in the question is true. Ceroid pigments and lipofuscin are products of cellular damage and aging. These substances accumulate within cells over time and can impair cellular functions, including the ability to withstand the damaging effects of oxygen free radicals. Choice B, 'False,' is incorrect because the accumulation of ceroid pigments and lipofuscin does indeed impair a cell's ability to deal with oxidative stress. Choices C and D are also incorrect as the statement is true.

2. You have been working closely with a patient for the past month. Today he tells you he is looking forward to meeting with his new psychiatrist but frowns and avoids eye contact while reporting this to you. Which of the following responses would most likely be therapeutic?

Correct answer: B

Rationale: Choice B is the most therapeutic response as it acknowledges the discrepancy between the patient's verbal statement and nonverbal cues. By addressing both the patient's expressed anticipation and the conflicting nonverbal cues of frowning and avoiding eye contact, the responder demonstrates attentiveness to the patient's emotional state and encourages further exploration of underlying feelings. This approach fosters open communication and helps the patient feel understood and supported.

3. A nurse is caring for a client who is receiving radiation therapy for breast cancer. Which of the following skin care instructions should the nurse provide?

Correct answer: A

Rationale: The correct answer is A: Wear loose clothing over the radiation site. Clients receiving radiation therapy should wear loose clothing over the treatment area to prevent irritation and promote healing. Choice B is incorrect as scented lotions can irritate the skin during radiation therapy. Choice C is incorrect because ice packs should not be applied to the radiation site as they can exacerbate skin reactions. Choice D is incorrect as exposing the radiation site to sunlight can increase skin damage and should be avoided.

4. What quality is observed among individuals who strive to find the best way to do their job?

Correct answer: D

Rationale: Motivation is the driving force that compels individuals to strive to find the best way to do their job. It encompasses determination, enthusiasm, and a proactive approach to continuously improve and excel in their work. Being motivated is essential for individuals in any profession to seek innovative solutions, achieve excellence, and make a meaningful impact. Punctuality, while important, refers to being on time rather than the drive to find the best way to do a job. Strictness relates to enforcing rules or discipline, not necessarily to seeking the best way. Honesty is about truthfulness and integrity, which are crucial but not directly related to the pursuit of excellence in job performance.

5. A nurse is planning care for a client who is receiving hemodialysis. Which of the following actions should the nurse include in the plan of care?

Correct answer: C

Rationale: The correct action the nurse should include in the plan of care for a client receiving hemodialysis is to check the vascular access site for bleeding after dialysis. This is crucial to detect any bleeding complications and ensure prompt intervention if necessary. Withholding all medications until after dialysis (Choice A) is not appropriate as some medications may need to be administered during dialysis. Rehydrating with dextrose 5% in water for orthostatic hypotension (Choice B) is not directly related to the immediate post-dialysis care. Giving an antibiotic 30 minutes before dialysis (Choice D) is not recommended as timing of medication administration should be based on the specific antibiotic and its pharmacokinetics.
