1. The healthcare professional seeks to assess the renal function of an elderly client who is about to receive a nephrotoxic medication. Which of the following labs provides the best indicator for renal function?

A. urinalysis
B. creatinine and blood urea nitrogen
C. chemistry of electrolytes
D. creatinine clearance

Correct answer: D

Rationale: In the context of an elderly client, assessing renal function before administering a nephrotoxic medication is crucial. While urinalysis and blood urea nitrogen provide valuable information on hydration status and overall health clues, they are not specific indicators of renal function. The chemistry of electrolytes may show abnormalities in renal failure, but it does not directly measure the kidneys' ability to eliminate waste. Creatinine clearance, on the other hand, is considered the best indicator for renal function in the elderly. This test accounts for decreases in lean body mass that can affect blood creatinine levels and is widely used to estimate the glomerular filtration rate, reflecting the kidneys' filtration capability. Therefore, creatinine clearance is the most appropriate lab test to assess renal function in this scenario.

2. Ms. Petty is having difficulty falling asleep. Which of the following measures promote sleep?

A. exercising vigorously for 20 minutes each night starting at 9:30 p.m.
B. taking a cool shower and drinking a hot cup of tea
C. watching TV nightly until midnight
D. getting a back rub and drinking a glass of warm milk

Correct answer: D

Rationale: Getting a back rub and drinking a glass of warm milk are appropriate measures to promote sleep as they can help relax the body and induce sleepiness. Exercising vigorously, as suggested in choice A, can be counterproductive as it stimulates the body rather than relaxing it, making it harder to fall asleep. Choice B, taking a cool shower and drinking a hot cup of tea, may also increase alertness due to the temperature changes and the caffeine in tea, which can interfere with falling asleep. Watching TV until midnight, as in choice C, exposes the individual to blue light and mental stimulation, making it harder to fall asleep. Therefore, choice D is the best option to promote sleep in this scenario.

3. What is the most likely reason for a hospitalized adult client who routinely works from midnight until 8 a.m. to have a temperature of 99.1�F at 4 a.m.?

A. delta sleep
B. slow brain waves
C. pneumonia
D. circadian rhythm

Correct answer: D

Rationale: The correct answer is 'circadian rhythm.' Circadian rhythms are biological cycles that last about 24 hours. The sleep-wake cycle is closely tied to circadian rhythms, affecting body temperature. Normally, core body temperature drops during sleep, reaching its 24-hour low around 4 a.m. In this case, the client's temperature of 99.1�F at 4 a.m. is likely due to the disruption of their circadian rhythm caused by working from midnight until 8 a.m. Choices A, B, and C are incorrect because delta sleep, slow brain waves, and pneumonia do not directly explain the temperature fluctuation based on circadian rhythm.

4. Which statement about clinical pathways is inaccurate?

A. They require daily updates.
B. They illustrate the expected client response to their diagnosis.
C. The objective is improvement or discharge from the facility.
D. They are evidence-based.

Correct answer: A

Rationale: The correct answer is that clinical pathways do not necessarily require daily updates. Clinical pathways can be customized to be updated daily, weekly, or at other intervals based on patient needs and facility protocols. Choice A is inaccurate as daily updates are not always mandatory for clinical pathways. Choices B, C, and D are accurate features of clinical pathways: they depict the expected client response to the diagnosis, aim for improvement or discharge, and are grounded in evidence-based practices to ensure optimal care.

5. A director of nursing at a long-term care center has announced a change to computerized documentation of nursing care. A certified nursing assistant (CNA) on the team, resistant to the change, is not taking an active part in facilitating the implementation of the new procedure. Which strategy would be the best approach to dealing with the conflict?

A. Meeting with the CNA and encouraging him to express his feelings regarding the change
B. Ignoring the resistance
C. Telling the CNA that a licensed practical nurse (LPN) will perform all computer documentation while he documents intake and output and vital signs
D. Telling the CNA that noncompliance will be documented in the personnel record

Correct answer: A

Rationale: The best approach to dealing with resistance to change is through open communication and understanding. Meeting with the CNA and encouraging him to express his feelings regarding the change allows for a constructive dialogue where issues can be addressed, and alternative solutions can be explored. Ignoring the resistance does not help in resolving the conflict and may lead to further issues. Telling the CNA that a licensed practical nurse (LPN) will perform all computer documentation while he documents intake and output and vital signs does not address the underlying concerns of the CNA and may create more resistance. Threatening the CNA with noncompliance consequences may escalate the resistance and create a negative work environment.
