Question 1 of 5
A client has been prescribed ciprofloxacin 400 mg intravenously (IV) every 12 hours to be infused over an hour. The IV bag contains ciprofloxacin 400 mg in dextrose 5% in water (D5W) 200 mL. How many mL/hour should the nurse program the infusion pump to deliver? (Enter numerical value only.)
Correct Answer: 200
Rationale: Infusion rate: 200 mL / 1 hr = 200 mL/hr. The pump should be set to deliver 200 mL/hr to administer ciprofloxacin correctly.
Question 2 of 5
A client taking atorvastatin has an increased serum creatine phosphokinase (CK) level. What should the nurse assess the client for?
Correct Answer: C
Rationale: Elevated CK with atorvastatin indicates possible myopathy, causing muscle tenderness (
C). Bruising (
A) is unrelated to CK. Edema (
B) suggests other causes. Nausea/vomiting (
D) are gastrointestinal side effects, not linked to CK.
Question 3 of 5
An older adult with iron deficiency anemia is being discharged with a prescription for ferrous sulfate enteric-coated tablets. To promote the best absorption of the medication, what information should the nurse include in the discharge instructions?
Correct Answer: C
Rationale: Ferrous sulfate is best absorbed on an empty stomach, 2 hours after meals (
C). Bedtime dosing (
A) isn’t specific to absorption. Crushing enteric-coated tablets (
B) disrupts their protective coating. Multivitamins (
D) may contain minerals that reduce iron absorption.
Question 4 of 5
A female client with multiple sclerosis reports having less fatigue and improved memory since she began using the herbal supplement, ginkgo biloba. What is the most important information for the nurse to include in the teaching plan for this client?
Correct Answer: C
Rationale: Ginkgo biloba increases bleeding risk, especially with aspirin/NSAIDs (
C), a critical interaction for safety. Nausea/diarrhea (
A) and anxiety/headaches (
D) are less severe. Pregnancy restrictions (
B) are relevant but secondary unless applicable.
Question 5 of 5
A patient is currently on an oral contraceptive and has been prescribed erythromycin. What advice should the nurse provide to the patient?
Correct Answer: A
Rationale: Erythromycin may reduce oral contraceptive efficacy by inducing hepatic metabolism. Using an additional contraceptive method (
A) prevents unintended pregnancy. Discontinuing the contraceptive (
B) is unnecessary. Timing gaps (
C) don’t mitigate the interaction. Sunlight avoidance (
D) relates to other antibiotics like tetracycline.
