A nurse is administering an intravenous (IV) infusion of 2 g cefotaxime dissolved in 100 mL of isotonic glucose solution to a client. The drop factor of the IV tubing is 15 drops/mL.
If the infusion time is 1 hr, what is the gt/min?

To find the milliliters per dose, you need to use the formula for dosage calculation:

Volume (mL) = Dose ordered (mg) / Concentration (mg/mL) x Volume available (mL)

Since the dose ordered is 0.5 grams, the concentration is 125 mg/5 mL, and the volume available is 5 mL, plug in these values into the formula:

Volume (mL) = 0.5 grams / 125 mg/5 mL x 5 mL

However, before you can simplify and solve for the volume, you need to convert the dose from grams to milligrams by multiplying by 1000:

Volume (mL) = 500 mg / 125 mg/5 mL x 5 m

Simplify and solve for the volume:

Volume (mL) = 20 mL

Therefore, the nurse should administer **20 mL** of Amoxil per dose to the patient.

This instruction should be given to the patient for the effective management of asthma because the patient is taking an overdose of ipratropium, which may cause serious side effects such as dry mouth, blurred vision, urinary retention, or increased heart rate. The recommended dosage of ipratropium for adults with acute asthma is 0.5 mg (500 mcg) every 20 minutes for three doses, followed by 0.5 mg every two to four hours as needed³. The patient's prescribed dose is 5 mg/kg, which means 300 mg/day for a 60 kg patient. This is 10 times the maximum daily dose of 2 mg (2000 mcg) for ipratropium⁴. Therefore, the patient should halve the dose of medication to 150 mg/day, which is still higher than the usual dosage, but within the range that can be given under medical supervision.

The other options are not appropriate instructions because:

a) Continuing the same dose of medication may worsen the patient's condition and increase the risk of adverse reactions.

b) Changing to alternative medication may not be necessary or effective, as ipratropium is a commonly used bronchodilator for asthma that works by relaxing the airway muscles and improving airflow⁵. The patient may benefit from adjusting the dose or adding other medications, such as corticosteroids or beta-agonists, depending on the severity and frequency of symptoms.

c) Doubling the dose of medication may be dangerous and potentially fatal, as it may cause severe anticholinergic effects, such as dry mouth, blurred vision, urinary retention, increased heart rate, confusion, or coma.
