NUR 340 Exam 3 Practice Questions and
Answers (100% Pass)

A nurse is preparing to administer the antibiotic for a hospitalized patient who

acquired a Methicillin-resistant Staph. aureus (MRSA) infection. Based on the

nurses' knowledge of antibiotics for the treatment of MRSA, which medication

may be ordered?

Vancomycin

Neomycin

Cefazolin

Ceftaroline

Metronidazole


Piperacillin - Answer✔️✔️-Answer: Vancomycin and ceftaroline




Rationale: Methicillin-resistant Staph. aureus(MRSA), highly resistant bacteria, are

resistant to all penicillins and all cephalosporins. Because most strains of MRSA

are multidrug resistant, many other antibiotics are ineffective, including

tetracyclines, clindamycin, trimethoprim/sulfamethoxazole, and beta-lactam agents

(except ceftaroline). Preferred drugs are IV vancomycin, linezolid [Zyvox],

daptomycin [Cubicin], telavancin [Vibativ], clindamycin, and ceftaroline. See

Lehne p. 1017

A nurse transcribes a new prescription for potassium penicillin G given

intravenously (IV) q 8 hours and gentamicin IV q 12 hours. Which plan is the best

schedule for administering these drugs?

a.) penicillin at 0800, 1600, and 2400; gentamicin at 1200 and 2400

b.) penicillin at 0600, 1400, and 2200; gentamicin at 0600 and 1800

c.) penicillin at 0800, 1600, and 2400; gentamicin at 0600 and 1800


d.) penicillin at 0100, 0900, and 1700; gentamicin at 0900 and 1800 - Answer✔️✔️-

Answer: C Rationale: Gentamicin should never be administered concurrently with

penicillin, because they will interact, and the penicillin may inactivate the

aminoglycoside. All options except A show concurrent administration. See Lehne

p. 1064

A patient who works as a landscaper is preparing to be discharged home.

Ciprofloxacin (Cipro) has been prescribed for outpatient therapy. Which of the

following will the nurse include in the discharge teaching for this patient?




"You may take the medication with milk of magnesia."

"Use sunscreen and protective clothing when outdoors."

"Take the medication with crackers and cheese."


"Take the medication until all symptoms subside." - Answer✔️✔️-"Use sunscreen

and protective clothing when outdoors."




Rationale: The patient, a landscaper, should be advised to wear sunscreen and

protective clothing when outdoors, because the medication may cause

phototoxicity. The medication should be taken until it is gone, not just until the

patient's symptoms are improved. Absorption of fluoroquinolones is reduced when

taken with a number of products including aluminum or magnesium containing

antacids and milk or other dairy products. See Lehne p. 1087

A hospitalized patient is receiving gentamicin (Garamycin) 80 mg IV twice daily

for acute osteomyelitis. Which data about the patient is most important for the

nurse to obtain before administering the gentamicin?




a.) oral temperature

b.) reports of nausea

c.) BUN and creatinine levels


d.) when an antacid was administered - Answer✔️✔️-Answer: C


Rationale: Although the patient's temperature will be monitored on a regular basis

in the hospital, gentamicin is nephrotoxic and can cause renal failure. Therefore

monitoring renal function is critical. Nausea is not a common side effect of IV

gentamicin. Because the drug is administered IV, an antacid will not affect

absorption of the gentamicin.

A patient has acquired hospital-associated MRSA. Which drug does the nurse

anticipate will be ordered to treat this infection?




vancomycin (Vancocin)
