The nurse 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: Due to decreases in lean body mass, blood creatinine is not as good an indicator of the elderly client's renal function as creatinine clearance. Creatinine clearance is a widely used test for glomerular filtration rate.

The charge nurse is observing nursing staff. In which activity illustrated should the charge nurse intervene because it places the nurse most at risk for back injury?
- A. intervene_1.PNG
- B. intervene_2.PNG
- C. intervene_3.PNG

Hearing screening of prematurely born infants is an effective means of identifying disease and is an example of:
- A. primary prevention.
- B. secondary prevention.
- C. tertiary prevention.
- D. disability prevention.
Correct Answer: B
Rationale: The three levels of prevention address disease and disability across all phases, from absence of disease and at risk for disease, to preventing further impairment. Hearing impairment associated with prematurity cannot be prevented by screening, but identifying the infants with hearing loss might prevent sequelae and further impairment by allowing early intervention.
