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 ["50"]
Explanation
To calculate the infusion rate in gtt/min, the nurse needs to use the formula:
Infusion rate (gtt/min) = Volume (mL) x Drop factor (gtt/mL) / Time (min)
Plugging in the given values, we get:
Infusion rate (gtt/min) = 400 mL x 60 gtt/mL / 480 min
Simplifying, we get:
Infusion rate (gtt/min) = 50 gtt/min
Therefore, the nurse should set the manual IV infusion to deliver 50 gtt/min.
Correct Answer is ["A","B","D"]
Explanation
A. Prayer:
Prayer is a spiritual practice that involves communicating with a higher power or deity. It has been used for centuries across various cultures and religions as a means of seeking guidance, comfort, and healing. While the direct physical effects of prayer on the body may not be well understood, many people find that prayer can provide emotional support, reduce stress, and promote a sense of well-being. Additionally, some research suggests that prayer may have positive effects on mental health and overall quality of life.
B. Meditation:
Meditation is a practice that involves focusing the mind and cultivating awareness, often through techniques such as mindfulness, breathing exercises, or guided imagery. It has been practiced for centuries in Eastern traditions such as Buddhism and Hinduism, as well as in other cultures around the world. Meditation is known for its ability to promote relaxation, reduce stress, and improve mental clarity. It has also been associated with numerous physical health benefits, including lower blood pressure, improved immune function, and better sleep.
C. Ointments with a steroid base:
Ointments with a steroid base are not typically considered CAM therapies. Instead, they are a form of conventional medical treatment commonly used to reduce inflammation and treat various skin conditions. These ointments contain corticosteroids, which are synthetic drugs that mimic the effects of hormones produced by the adrenal glands. They work by suppressing the body's immune response and reducing inflammation in the affected area. While steroid-based ointments can be effective for treating certain skin conditions, they are not part of traditional CAM practices.
D. Massage:
Massage therapy involves manipulating the body's soft tissues, including muscles, tendons, and ligaments, to promote relaxation, relieve muscle tension, and improve circulation. It has been practiced for centuries in cultures around the world and is commonly used to alleviate stress, reduce pain, and enhance overall well-being. Massage therapy encompasses various techniques, such as Swedish massage, deep tissue massage, and aromatherapy massage, each with its own benefits and applications. Research has shown that massage therapy can have numerous physical and mental health benefits, including reduced anxiety, improved mood, and enhanced immune function.
