Question 1 of 5
A nurse is reinforcing teaching with a client who has a prescription for oral suspension phenytoin. Which of the following information should the nurse include in the teaching?
Correct Answer: C
Rationale: Phenytoin suspension should be shaken vigorously to ensure even distribution of the medication.
Question 2 of 5
A nurse is caring for a client who has a prescription for digoxin 0.25 mg PO daily. The amount available is digoxin 0.125 mg/tablet. How many tablets should the nurse administer per dose? (Round to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: B
Rationale: Prescription: 0.25 mg, Available: 0.125 mg/tablet, Tablets needed = Prescription / Available = 0.25 mg / 0.125 mg/tablet = 2 tablets.
Question 3 of 5
A nurse is caring for a client who has a new prescription for warfarin. The nurse should use the results of which of the following diagnostic tests to monitor the effect of this therapy?
Correct Answer: C
Rationale: Prothrombin time (PT) is the test used to monitor the effectiveness of warfarin therapy and is often expressed as an International Normalized Ratio (INR).
Question 4 of 5
A nurse is preparing to administer 400 mL of 0.9% sodium chloride IV over 8 hr. The drop factor of the manual IV tubing is 60 gtt/mL. The nurse should set the manual IV infusion to deliver how many gtt/min? (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: Calculation:
Total volume (mL) = 400 mL,
Total time (hr) = 8 hr = 480 min, Drops per minute (gtt/min) = (
Total volume × Drop factor) /
Total time, gtt/min = (400 mL × 60 gtt/mL) / 480 min = 50 gtt/min.
Question 5 of 5
A nurse is caring for a client who has a prescription for digoxin 0.25 mg PO daily for heart failure. The client's current vital signs are: BP 144/96, heart rate 54/min, respirations 18/min, and temperature 37° C (98.6° F). Which of the following actions should the nurse take?
Correct Answer: B
Rationale: A heart rate below 60 beats per minute is a contraindication for administering digoxin, as it can increase the risk of toxicity and bradycardia.
