Question 1 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 2 of 5
A nurse is preparing to administer enteric-coated aspirin to an older adult client who had a cerebrovascular accident and has difficulty swallowing medications. The client asks the nurse if she will crush the medication to make it easier to swallow. Which of the following responses should the nurse make?
Correct Answer: C
Rationale: Crushing enteric-coated aspirin would cause the medication to be released all at once, potentially leading to side effects and reducing its intended effectiveness.
Question 3 of 5
A nurse is preparing a medication for a client and is converting grams to milligrams. Which of the following actions should the nurse take?
Correct Answer: C
Rationale:
To convert grams to milligrams, the nurse must multiply by 1,000, which involves moving the decimal point 3 places to the right (1 gram = 1000 mg).
Question 4 of 5
A nurse is preparing to administer enteric-coated aspirin to an older adult client who had a cerebrovascular accident and has difficulty swallowing medications. The client asks the nurse if she will crush the medication to make it easier to swallow. Which of the following responses should the nurse make?
Correct Answer: C
Rationale: Crushing enteric-coated aspirin would cause the medication to be released all at once, potentially leading to side effects and reducing its intended effectiveness.
Question 5 of 5
A nurse is assisting in preparing an in-service program about preventing medication errors when transcribing a prescription. The nurse is using a dosage example of two tenths of a milligram. Which of the following transcription examples should the nurse use?
Correct Answer: B
Rationale: 0.2 mg is the proper way to write two tenths of a milligram, with a leading zero to prevent misinterpretation.
