Pneumonia in a hospitalized patient.

Chronic urinary tract infection for a homebound patient.

A sexually transmitted infection in a healthy young adult.

Answer and Explanation

The Correct Answer is B

A.   A person with diabetes who requires hospitalization for cellulitis: Cellulitis may not necessarily be a healthcare-associated infection unless it developed as a complication during the hospitalization.
B.   Pneumonia in a hospitalized patient: Pneumonia acquired during a hospital stay is considered a healthcare-associated infection (HAI) because it develops after 48 hours of hospital admission.
C.   Chronic urinary tract infection for a homebound patient: A chronic urinary tract infection in a homebound patient is not automatically considered a healthcare-associated infection unless it can be directly linked to healthcare interventions or devices.
D.   A sexually transmitted infection in a healthy young adult: Sexually transmitted infections are not healthcare-associated infections as they are typically acquired through sexual contact rather than healthcare settings.

Correct Answer is B

Explanation

A. Amoxicillin: Amoxicillin is a penicillin-type antibiotic effective against susceptible bacteria, but it is not effective against MRSA because MRSA is resistant to penicillin and related antibiotics.

C. Fluconazole: Fluconazole is an antifungal medication used to treat fungal infections such as candidiasis. It is not effective against bacterial infections like MRSA.
D. Abreva: Abreva is an over-the-counter medication used to treat cold sores caused by the herpes simplex virus. It is not effective against bacterial infections like MRSA.

Correct Answer is ["7"]

Explanation

Dosage required / Dosage strength = Volume to administer
1. Identify the required dose: 350 mg.
2. Identify the available medication strength: 250 mg of amoxicillin in every 5 mL.
3. Set up the equation using the formula: 350 mg / 250 mg = Volume to administer / 5 mL.
4. Solve for the volume to administer: (350 mg / 250 mg) x 5 mL = 7 mL.

Therefore, the nurse should administer 7 mL
