Question 1 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 2 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.
Question 3 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 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 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).
