Question 1 of 5
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?
Correct Answer: A
Rationale: 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).
Question 2 of 5
A nurse is teaching a client who has hypertension and a new prescription for atenolol. Which of the following findings should the nurse include as adverse effects of this medication?

Rationale: Bradycardia (slow heart rate) is a known adverse effect of atenolol, a beta-blocker that can decrease heart rate and blood pressure.
Question 3 of 5
A nurse is reviewing the EKG strip of a client who has prolonged vomiting. Which of the following abnormalities on the client's EKG should the nurse interpret as a sign of hypokalemia?

Question 4 of 5
A nurse is preparing to administer 0.9% sodium chloride IV infusion 1-L bag at a rate of 200 mL/hr for a client who has rhabdomyolysis. The nurse should expect the IV pump to infuse over how many hours? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: A
Rationale:
To calculate the infusion time for a 1-L bag of 0.9% sodium chloride at a rate of 200 mL/hr, you would divide the total volume of the IV bag by the hourly infusion rate. Since there are 1000 mL in a 1-L bag, you would calculate 1000 mL divided by 200 mL/hr, which equals 5 hours.
