Order: Ampicillin 1 g is added to 50 mL DSW to infuse over 45 minutes. Drop factor: 10 gtt/mL. For IV reconstitute with 10 mL of diluent to get 1 g per 10 mL. (Consider the medication added in the volume of fluid.) Calculate the rate in gtt/min at which the should infuse

Given:

Volume of Glucerna 1.2: 237 mL

Desired concentration: 1/2 strength

Step 1: Determine the volume of Glucerna 1.2 needed for the half-strength solution:

Volume of Glucerna 1.2 for half-strength = Original volume / 2

Volume of Glucerna 1.2 for half-strength = 237 mL / 2

Volume of Glucerna 1.2 for half-strength = 118.5 mL

Step 2: Calculate the amount of water to be added:

Amount of water = Original volume - Volume of Glucerna 1.2 for half-strength

Amount of water = 237 mL - 118.5 mL

Amount of water = 118.5 mL

A) Infections become resistant to high doses of antibiotics:
Methicillin-resistant Staphylococcus aureus (MRSA) is a strain of Staphylococcus aureus that has become resistant to the antibiotic methicillin, as well as other beta-lactam antibiotics (such as penicillin and cephalosporins). Over time, bacteria can develop resistance mechanisms, often as a result of antibiotic misuse or overuse, such as not completing a full course of treatment or using antibiotics unnecessarily. MRSA, in particular, can grow resistant to higher and higher doses of standard antibiotics, making treatment more challenging.

B) Antibiotic dosages below the minimum concentration are prescribed:
Antibiotic dosages should always be prescribed at the minimum inhibitory concentration (MIC), which is the lowest concentration of the drug that can inhibit bacterial growth. Prescribing antibiotics below this concentration would not be effective in treating the infection and could contribute to antibiotic resistance.

C) Antibiotics are prescribed only when a viral infection is present:
Antibiotics, including those prescribed for MRSA, are only effective against bacterial infections, not viral infections. For viral infections (such as the flu or common cold), antibiotics should not be used, as they are ineffective. MRSA is a bacterial infection, and it requires appropriate antibiotic therapy specifically targeted to the bacteria, not a viral infection.

D) Broad-spectrum antibiotics are used whenever possible:
While broad-spectrum antibiotics are sometimes used in initial treatments when the specific bacterial pathogen is unknown, their overuse can contribute to the development of antibiotic resistance. In the case of MRSA, a more targeted approach with antibiotics specifically effective against resistant strains (like vancomycin or clindamycin) is preferred.
