Extract:
Question 1 of 5
A nurse is collecting data from a client prior to the administration of digoxin. Which of the following findings should the nurse report to the provider?
Correct Answer: A
Rationale: A potassium level of 3.0 mEq/L (hypokalemia) increases digoxin toxicity risk and should be reported. Other values are within normal ranges.
Question 2 of 5
A nurse is preparing to administer nitroglycerine 15 mcg/min by continuous IV infusion. Available is nitroglycerin 25 mg in 250 mL of dextrose 5% in water (D5W). 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: A
Rationale: Dose = 15 mcg/min × 60 = 900 mcg/hr. Concentration = 25 mg / 250 mL = 100 mcg/mL. Flow rate = 900 / 100 = 9 mL/hr.
Question 3 of 5
Calculate the following dosage using ratio and proportions method (Round answers to the nearest tenth). Order: Digoxin 0.375mg p. o. daily. Available: Digoxin (scored tablets) labeled 0.25mg
Correct Answer: B
Rationale: Tablets = 0.375 mg / 0.25 mg/tablet = 1.5 tablets.
Question 4 of 5
Which one is not a step of pharmacokinetics?
Correct Answer: D
Rationale: Synthesis is drug creation, not a pharmacokinetic process like absorption, distribution, or metabolism.
