Extract:
Question 1 of 5
A nurse is caring for a client who is receiving warfarin therapy to prevent a deep vein thrombosis. Which of the following medications should the nurse have available in the event of an overdose?
Correct Answer: C
Rationale: Vitamin K is the antidote for warfarin overdose, reversing its anticoagulant effects.
Question 2 of 5
A nurse is reviewing the morning laboratory results of electrolytes for four clients who are receiving digoxin. Which of the following clients should the nurse identify as being at risk for developing digoxin toxicity?
Correct Answer: A
Rationale: Furosemide can cause hypokalemia, which increases the risk of digoxin toxicity.
Question 3 of 5
A nurse is preparing to administer 0.9% sodium chloride (NaCl) 750 mL IV to infuse over 8 hr. The nurse should set the IV pump to deliver how many mL/hr? (Round to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: 94 mL/hr
Rationale:
To calculate the infusion rate, divide the total volume (750 mL) by the total infusion time (8 hr): 750 mL / 8 hr = 93.75 mL/hr. Rounding to the nearest whole number gives 94 mL/hr.
Question 4 of 5
A nurse is preparing to administer hydrochlorothiazide 25 mg PO every 8 hr. The amount available is hydrochlorothiazide 50 mg/tab. How many tablets should the nurse administer per dose? (Round the answer to the nearest tenth/whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: 0.5 tablets.
Rationale:
To determine the number of tablets, divide the desired dose (25 mg) by the available strength (50 mg/tablet): 25 mg / 50 mg/tablet = 0.5 tablets.
Question 5 of 5
A nurse is reviewing the chart of a client who is scheduled to have radiological studies of the kidneys performed with the use of IV contrast dye. Which of the following client medications should the nurse withhold prior to the examination?
Correct Answer: D
Rationale: Metformin should be withheld prior to procedures involving contrast dye because it can increase the risk of lactic acidosis when combined with contrast agents, especially in clients with renal impairment.
