The nurse is administering medications to an elderly patient. Which laboratory tests are important for the nurse to assess prior to the administration of medication?
1. Complete blood count (CBC) and electrolytes
2. Kidney and liver function tests
3. Arterial blood gases (ABGs) and basic metabolic panel
4. Lipid panel and thyroid function tests
Correct Answer: 2
Rationale: Renal and hepatic function tests are essential for many patients, particularly older patients and those who are critically ill, as these will be used to determine the proper drug dosage. Complete blood count (CBC) and electrolytes will not help to determine the proper drug dosage. Lipid panel and thyroid function tests will not help to determine the proper drug dosage. Arterial blood gases (ABGs) and a basic metabolic panel will not help to determine the proper drug dosage.
