Question 1 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 2 of 5
A nurse is preparing to administer diazepam 3 mg IM. The amount available is diazepam for injection 5 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: B
Rationale: Amount prescribed: 3 mg, Amount available: 5 mg/mL, mL needed = Amount prescribed / Amount available = 3 mg / 5 mg/mL = 0.6 mL.
Question 3 of 5
A nurse is preparing to administer diazepam 3 mg IM. The amount available is diazepam for injection 5 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: B
Rationale: Amount prescribed: 3 mg, Amount available: 5 mg/mL, mL needed = Amount prescribed / Amount available = 3 mg / 5 mg/mL = 0.6 mL.
Question 4 of 5
A nurse administers the wrong medication to a client. Which of the following actions should the nurse take first?
Correct Answer: D
Rationale: Checking the client's vital signs first helps determine if the client is experiencing any negative effects from the medication error, ensuring immediate safety.
Question 5 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.
