The nurse is caring for a patient who receives a divided dose of IV amikacin (Amikin) twice a day. When will the nurse draw blood for measurement of a trough aminoglycoside level?
A.) just prior to administration of the next dose.B.) 1 hour before the next dose.C.) 30 minutes after the IV infusion is complete.D.) 1 hour after the IV infusion is complete. - ANSWER-
Answer: A
Rationale: When divided daily doses are prescribed,
blood samples for measurement of trough levels are drawn immediately before administration of the next dose. This is the time at which the blood levels of the 1 / 4
- | P a g e
drug are at the lowest. To obtain peak levels, the nurse will draw a blood sample 30 after infusion the infusion is complete when the most drug is in the patient's bloodstream. See Lehne pp. 1056
The nurse administers ceftriaxone to a patient who also is taking warfarin. The nurse will monitor the patient carefully for which problem?
bruising or bleeding gums hyperkalemia increased neutrophil counts
elevated levels of ceftriaxone - ANSWER-Answer:
Bruising or bleeding gums
Rationale: The nurse should monitor the patient for
bruising or bleeding gums, because ceftriaxone can promote bleeding, especially when administered concurrently with warfarin. The combination of these
- drugs does not alter the effectiveness of the
antibiotic; monitoring neutrophils will provide information only about the stage of the infection.Monitoring ceftriaxone levels provides information 2 / 4
- | P a g e
about whether the drug levels are sufficient to address the infection. Neither drug impacts the patient's potassium levels. See Lehne p. 1027
The nurse notifies the health care provider that a patient who is concurrently taking ciprofloxacin and warfarin.What change to the patient's medication dosages does the nurse anticipate?
A.) increase in the ciprofloxacin dose.B.) decrease in the ciprofloxacin dose.C.) increase in the warfarin dose.
D.) decrease in the warfarin dose. - ANSWER-Answer:
D
Rationale: Ciprofloxacin can elevate levels of warfarin
in the blood which will cause more warfarin to be available and will thereby further decrease the patient's ability to clot. Decreasing the warfarin dosage while the patient is on ciprofloxacin will help keep the patient's clotting time within therapeutic range. The prothrombin time and INR level should be 3 / 4
- | P a g e
monitored, and the dosage of warfarin should be reduced as indicated. See Lehne p. 1087
The nurse on a medical-surgical unit is caring for a patient experiencing fever of unknown origin. The prescriber has ordered a broad-spectrum antibiotic. Which intervention is the nurse's priority?
Delay administration of the antibiotic until culture results are available.Administer an antipyretic as soon as possible.Obtain all cultures before the antibiotic is administered.Administer the antibiotic as soon as it is available. -
ANSWER-Answer: Obtain all cultures before the
antibiotic is administered
Rationale: It is essential that samples of exudates and
body fluids (in this case, blood cultures) be obtained for culture prior to initiation of treatment.Administration of the antibiotic is important, but not more important than obtaining specimens for culture.
