The nurse is admitting a client to the acute care floor with methicillin-resistant S. aureus. The nurse would expect the physician to order which of the following medications for the client?
kanamycin (Kantrex)
vancomycin
streptomycin
penicillin
The Correct Answer is B
A. Kanamycin (Kantrex):
Kanamycin is an aminoglycoside antibiotic, but it is not commonly used as a first-line treatment for MRSA infections. Aminoglycosides are not typically preferred for treating MRSA because they are not as effective against these resistant bacteria compared to other agents like vancomycin.
B. Vancomycin:
Vancomycin is a glycopeptide antibiotic and is considered the drug of choice for the treatment of MRSA infections, including serious bloodstream infections, pneumonia, and skin and soft tissue infections. It works by inhibiting cell wall synthesis in bacteria, including MRSA.
C. Streptomycin:
Streptomycin is another aminoglycoside antibiotic, similar to kanamycin. Like kanamycin, streptomycin is not typically used as a first-line treatment for MRSA infections because it is less effective against resistant strains compared to other agents like vancomycin.
D. Penicillin:
Penicillin and other beta-lactam antibiotics are ineffective against MRSA because MRSA is resistant to these antibiotics, including methicillin. Therefore, penicillin would not be an appropriate choice for treating MRSA infections.

Correct Answer is B
Explanation
- Abdominal surgery requires starting antibiotic therapy 4 days before surgery:
This statement is not accurate. While antibiotic prophylaxis is commonly administered before certain types of surgery to prevent surgical site infections, the timing and duration of antibiotic therapy vary depending on factors such as the type of surgery, the patient’s medical history, and institutional guidelines. However, starting antibiotic therapy four days before surgery would not be standard practice for most abdominal surgeries.
B. A reduction of intestinal bacteria lessens the possibility of postoperative infection:
This statement is correct. Neomycin, as well as other antibiotics used in bowel preparation regimens, help reduce the population of intestinal bacteria. By decreasing the bacterial load in the bowel before surgery, the risk of contaminating the surgical site with harmful bacteria during the procedure is reduced, thus lowering the likelihood of postoperative infections.
C. The bacteria found in the bowel cannot be destroyed after surgery:
This statement is incorrect. While it is true that the bowel contains a complex ecosystem of bacteria that play important roles in digestion and other physiological functions, the population of intestinal bacteria can be temporarily reduced through the use of antibiotics, such as neomycin, as part of a bowel preparation regimen before surgery.
D. Anesthesia makes the bowel resistant to an antibiotic after surgery:
This statement is not accurate. Anesthesia does not render the bowel resistant to antibiotics after surgery. However, the administration of antibiotics during surgery and postoperatively may be indicated in certain cases to prevent or treat infections, particularly if the surgical procedure involves contamination of the abdominal cavity or if the patient is at increased risk of infection.
Correct Answer is A
Explanation
A. Ototoxicity:
Ototoxicity refers to damage to the auditory and vestibular nerves, leading to hearing loss and balance disturbances. Gentamicin, being an aminoglycoside antibiotic, is known for its potential to cause ototoxicity. Signs and symptoms of ototoxicity include changes in hearing, ringing in the ears (tinnitus), and imbalance. Ototoxicity is irreversible and can occur suddenly or gradually during gentamicin therapy. Therefore, any signs or symptoms of ototoxicity should be reported immediately to the physician for further evaluation and management.
B. Nausea:
Nausea is a common gastrointestinal side effect associated with gentamicin therapy. While it can be bothersome to the patient, nausea alone is not typically considered a severe adverse effect that requires immediate reporting to the physician. However, if nausea is severe or persistent and leads to dehydration or electrolyte imbalances, it should be addressed promptly.
C. Constipation:
Constipation is another potential gastrointestinal side effect of gentamicin therapy. Like nausea, constipation alone is not typically considered a severe adverse effect that requires immediate reporting to the physician. However, if constipation is severe or persistent and leads to discomfort or bowel obstruction, it should be addressed promptly.
D. Increased urinary output:
Increased urinary output may indicate improved renal function, which can be a desired effect during gentamicin therapy. Gentamicin is primarily excreted by the kidneys, and increased urinary output may help in the elimination of the drug from the body. Therefore, increased urinary output alone is not typically considered an adverse effect that requires immediate reporting to the physician. However, if there are signs of dehydration or electrolyte imbalances associated with increased urinary output, they should be addressed promptly.
