The nurse notes a medication ordered for a client is advised to use with caution in the elderly due to declining renal function. Which of the following nursing interventions is an example of a precaution?
Administering medications different times during the day
Compare the clients armband with the medication administration record
Closely monitoring the clients BUN and creatine for a decrease from baseline
closely monitoring the clients BUN and creatine for an increase from baseline
The Correct Answer is D
A. Administering medications at different times: timing does not affect renal function monitoring.
B. Comparing the client’s armband with the MAR: this is a safety check, not a precaution for renal function.
C. Monitoring for a decrease in BUN and creatinine: a decrease does not indicate renal impairment.
D. Closely monitoring the client's BUN and creatinine for an increase from baseline: Renal function declines with age, increasing the risk of drug accumulation and toxicity. An increase in BUN (normal: 7-20 mg/dL) and creatinine (normal: 0.6-1.3 mg/dL) indicates worsening kidney function and necessitates medication adjustments.

Correct Answer is B
Explanation
A. "This test shows if I am dehydrated." aPTT is not used to assess hydration status; it measures blood clotting ability.
B. "This test measures deficiencies in clotting factors." aPTT assesses the intrinsic clotting pathway and helps evaluate clotting factor deficiencies, especially in conditions like hemophilia or when a client is on heparin therapy.
C. "If my level is too low, I need to consume more sodium." Sodium intake does not directly impact aPTT values.
D. "The aPTT is used to measure my sugar levels." Glucose levels are measured by a blood sugar test, not an aPTT test.
Correct Answer is D
Explanation
A. Medications that limit the receptor activity: This describes an antagonist, which reduces or limits receptor activity.
B. Medications that block the receptor activity: This also describes an antagonist, which prevents receptor activation.
C. Medications that change the receptor activity: This statement is vague and does not clearly define an agonist.
D. Medications that activate the receptor activity and are synergistic: An agonist binds to a receptor and stimulates a response, often enhancing normal physiological functions.
