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?

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.

Correct Answer: C

Rationale: All nurses should be concerned with preventing the transmission of microorganisms to themselves and others. A primary way to achieve this is through asepsis. Nursing practice emphasizes providing a safe environment to shield clients, family, and healthcare providers from infections. Choices A, B, and D are incorrect. While drug-resistant bacteria, critical microorganisms, and overprescription of bacteriostatic drugs are important, nurses' primary focus should be on preventing microorganism transmission to ensure safety and well-being.

Correct Answer: B

Rationale: The correct answer is 'the severity of the client's condition and the priority decision.' When determining the method of splinting, it is crucial to consider the severity of the client's condition and make decisions based on their priority. Choice A is incorrect because while the location of the injury and whether it is open or closed are important factors, they do not always dictate the method of splinting. Choice C is incorrect as the number of available rescuers and the type of splints may impact the execution of splinting but do not solely dictate the method. Choice D is incorrect as it suggests that all the factors mentioned dictate the method, but in reality, the severity of the client's condition and the priority decision are the primary factors.

Correct Answer: D

Rationale: The correct answer is infant rice cereal. Single-grain infant cereals are recommended as the first solid food because they are easily digestible and have added iron content. Choice C, yogurt, is incorrect because yogurt is a milk product and should be delayed until the child is 12 months old due to the risk of milk allergy. Choices A and B are incorrect because fruits and vegetables are typically introduced after cereals to help the infant get accustomed to solid foods gradually.

Correct Answer: A

Rationale: Pressure ulcers usually occur over bony prominences and are caused by decreased circulation. The client who is left in one position in bed for extended periods of time is more prone to decreased circulation to an area of the body and to acquiring a pressure ulcer. Choices B and C are incorrect as pressure ulcers are not exclusive to underweight or overweight clients. The key factor is prolonged pressure on the skin, not the weight of the client. Therefore, the correct answer is that pressure ulcers are most likely to occur when clients are immobilized in one position for extended periods of time.
