Question 1 of 5
The factor that most determines drug distribution is:
Correct Answer: A
Rationale: Drugs are distributed via the circulatory system. Adequate perfusion is necessary for distribution of a drug. The other choices are not as dependent on adequate perfusion.
Question 2 of 5
The hospitalized client is prescribed to receive ferrous fumarate 200 mg oral daily. When transcribing the medication onto the client's MAR, at which time in military time should the nurse schedule the daily dose for best absorption?
Correct Answer: B
Rationale: A: 0830 is near the time of breakfast in a health care facility. Food reduces the absorption of iron. B: For best absorption and therapeutic effectiveness, the nurse should schedule ferrous fumarate (Feosol) at 1000. Iron preparations should be administered one hour before or two hours after a meal because food diminishes iron absorption. C: 1230 is near lunchtime in a health care facility. Food reduces the absorption of iron. D: 1730 is near the evening meal in a health care facility. Food reduces the absorption of iron.
Question 3 of 5
The HCP orders a digitalizing dose of digoxin 225 mcg IV now to be given to a 3-year-old. The pharmacy sends a solution of 500 mcg in 50 mL of D5W. How many mL should the nurse administer?
Correct Answer: 22.5
Rationale: Use a proportion formula: 500 mcg : 50 mL :: 225 mcg : X mL; 500X = 11250; X = 22.5 mL.
Question 4 of 5
Ciprofloxacin is prescribed for the client to treat a UTI. Which information should the nurse stress when teaching the client about the medication?
Correct Answer: A
Rationale: A: Ciprofloxacin (Cipro) is a fluoroquinolone antibiotic. Milk or yogurt decreases its absorption and should be avoided. B: Bismuth subsalicylate decreases the absorption of ciprofloxacin and should be avoided. C: Fennel will decrease, not increase, the absorption of the ciprofloxacin. D: Dietary calcium can be taken at any time; it is unaffected by ciprofloxacin.
Question 5 of 5
The client calls a clinic to renew the prescription for insulin being administered subcutaneously via an insulin pump. Which insulin type, if prescribed by the HCP, should the nurse question?
Correct Answer: D
Rationale: A: Lispro (Humalog) is a rapid-acting human insulin analog that can be delivered via an insulin pump. B: Aspart (NovoLog) is a rapid-acting human insulin analog that can be delivered via an insulin pump. C: Glulisine (Apidra) is a rapid-acting human insulin analog that can be delivered via an insulin pump. D: The nurse should question if glargine (Lantus) is prescribed. Glargine is long-duration insulin not suited for delivery by an infusion pump.
