A nurse is concerned about renal function in an 84-year-old client who is taking several medications. What is a priority for the nurse to assess?
Serum creatinine
Troponin levels
Specific gravity
Sodium levels
The Correct Answer is C
A) Serum creatinine is an important marker of renal function, but specific gravity is more directly related to urine concentration and kidney function.
B) Troponin levels are primarily associated with cardiac function, not renal function.
C) Assessing specific gravity helps evaluate the kidney's ability to concentrate urine and is a valuable indicator of renal function.
D) Sodium levels can be important in assessing electrolyte balance but are not the primary indicator of renal function.

B) Calcium interferes with the absorption of ciprofloxacin, so they should be taken at least six hours apart to avoid decreased effectiveness of the antibiotic.
C) Stopping calcium supplements may not be necessary, but proper timing is crucial.
D) Taking the medications together can reduce the absorption of both, so they should be spaced apart.
Correct Answer is A
Explanation
Rationale for A: Ibuprofen is generally considered safe for use while breastfeeding, as it passes into breast milk in small amounts that are not expected to harm the infant.
Rationale for B: Lithium can have serious effects on a breastfeeding infant, as it can cause lethargy and developmental issues. Its use is generally not recommended during breastfeeding.
Rationale for C: Methotrexate is contraindicated during breastfeeding due to its potential toxicity and harmful effects on the infant, including possible effects on growth and development.
