Final answer:
To monitor for adverse effects of gentamicin in a patient with diabetes and pneumonia, the nurse will focus on the patient's blood urea nitrogen (BUN) and creatinine levels to assess potential kidney damage.
Step-by-step explanation:
When evaluating for adverse effects of the medication gentamicin (Garamycin), which is an antibiotic used to treat infections such as pneumonia, the nurse will plan to monitor the patient's blood urea nitrogen (BUN) and creatinine. This is because gentamicin is known to be nephrotoxic, meaning that it can potentially cause damage to the kidneys. By monitoring BUN and creatinine levels, healthcare professionals can assess kidney function and detect any signs of impairment early.
It is important to note that while monitoring blood glucose levels is crucial for a patient with diabetes, gentamicin does not typically affect blood glucose levels directly. Similarly, while serum potassium and urine osmolality are valuable tests for other conditions, they are not the primary focus for monitoring gentamicin-related kidney toxicity.
