Convert the following metric measures to kg by moving the decimal: 5,524 g

A) Yes. Antacids can help alleviate heartburn caused by digoxin.
While antacids can help relieve heartburn, they do not directly alleviate heartburn caused by digoxin. In fact, antacids can interact with digoxin in a way that affects its absorption, potentially leading to suboptimal therapeutic effects.

B) Yes, you can take antacids with digoxin without any interactions.
Antacids can interact with digoxin and reduce its absorption, particularly those that contain aluminum, magnesium, or calcium. Therefore, it is important to space the administration of these medications to avoid potential drug interactions.

C) Yes, but make sure to take the antacid at least 2 hours before or after taking digoxin.. Antacids, especially those containing aluminum, calcium, or magnesium, can decrease the absorption of digoxin, reducing its effectiveness. To prevent this interaction, the nurse should advise the client to take the antacid at least 2 hours before or after taking digoxin to ensure that digoxin is properly absorbed and remains effective.

D) No, antacids can decrease the absorption of digoxin and result in a decreased drug effect.
While this statement is partly true in that antacids can decrease digoxin absorption, it is too absolute to recommend avoiding antacids altogether. The key is proper timing—taking antacids at least 2 hours apart from digoxin.

Given:

Ordered dose of phenobarbital: 6 mg/kg/day divided equally every 12 hours

Patient weight: 44 lbs

Concentration of phenobarbital elixir: 20 mg/5 mL

Step 1: Convert patient weight from pounds to kilograms:

1 pound (lb) = 0.453592 kilograms (kg)

Patient weight in kg = 44 lbs x 0.453592 kg/lb = 19.958 kg

Step 2: Calculate the total daily dose of phenobarbital:

Total daily dose (mg) = Ordered dose (mg/kg/day) x Patient weight (kg)

Total daily dose (mg) = 6 mg/kg/day x 19.958 kg

Total daily dose (mg) = 119.748 mg/day

Step 3: Calculate the dose per administration:

Dose per administration (mg) = Total daily dose (mg) / Number of administrations per day

Dose per administration (mg) = 119.748 mg/day / 2 administrations/day

Dose per administration (mg) = 59.874 mg

Step 4: Calculate the volume to be administered per dose:

Volume (mL) = Dose per administration (mg) / Concentration (mg/mL)

Volume (mL) = 59.874 mg / (20 mg/5 mL)

Volume (mL) = 59.874 mg x (5 mL / 20 mg)

Volume (mL) = 14.9685 mL

Step 5: Round to the nearest whole number:

Volume (mL) ≈ 15 mL
