A nurse is caring for a client whose serum potassium level is 5.3 mEq/L. Which of the following scheduled medications should the nurse plan to administer?
Furosemide
Potassium iodide
Digoxin
Lisinopril
The Correct Answer is A
Rationale:
A. Furosemide is a loop diuretic that helps to lower potassium levels, making it appropriate for a client with hyperkalemia (potassium level of 5.3 mEq/L).
B. Potassium iodide would further increase potassium levels, which is contraindicated in this situation.
C. Digoxin does not directly affect potassium levels and could be dangerous in the context of hyperkalemia.
D. Lisinopril is an ACE inhibitor that can increase potassium levels, which would not be appropriate for this client.

Correct Answer is ["200"]
Explanation
To calculate the infusion rate in mL/hr for administering clindamycin 900 mg in 100 mL dextrose 5% over 30 minutes, you would use the formula: (Total Volume in mL / Time in hours) = Rate in mL/hr. Since the medication needs to be administered over 30 minutes, you convert 30 minutes into hours, which is 0.5 hours. Using the formula, you get (100 mL / 0.5 hours) = 200 mL/hr. Therefore, the nurse should set the IV pump to deliver 200 mL/hr.
Correct Answer is ["A","B","D","F"]
Explanation
A. Peripheral IV in large vein
Vancomycin should be administered through a large-bore IV to minimize the risk of complications such as phlebitis and to ensure effective drug delivery. This is a key factor in safely administering the medication.
B. Dosage in safe range
Confirming that the dosage is within the safe range ensures that the medication is administered at an effective but non-toxic level. Proper dosing is essential for achieving therapeutic effects without causing harm.
C. No known allergies
Ensuring that the client has no known allergies to vancomycin is critical to prevent allergic reactions. This step is necessary for the safe administration of the antibiotic.
D. Potassium 4.4 mEq/L (4.4 mmol/L)
While normal potassium levels are important for overall health, they do not specifically indicate the safety of vancomycin administration. Other factors such as IV access and dosage are more directly related to the safety of vancomycin.
E. Used for prophylaxis
Vancomycin is used for endocarditis prophylaxis in this case, which aligns with the clinical guidelines for preventing infections. Understanding the purpose of the medication supports its appropriate use in the client’s care.
F. Blood urea nitrogen 17 mg/dL (6.07 mmol/L)
An elevated BUN level might indicate renal impairment, which could affect vancomycin metabolism. However, this level alone does not directly address the immediate safety of administering the antibiotic compared to other factors like IV access and dosage.
