A client with chronic constipation reports taking 2 ounces of magnesium hydroxide at bedtime. The bottle is labeled "Magnesium hydroxide saline laxative, USP 400 mg per 5 mL. How many mL should the nurse document in the medical record? (Enter numerical value only.)
Answer and Explanation

The Correct Answer is ["59.147"]

Here's how to calculate the number of mL the nurse should document:

Client dosage: 2 ounces (given)

Conversion factor: 1 ounce (oz) = 29.5735 mL (conversion factor)

Magnesium hydroxide concentration: 400 mg per 5 mL (from bottle label)

We need to find the equivalent volume in mL of the 2 ounces dosage the client reported.

Steps:

a. Convert ounces to mL:

Client dosage (mL) = Client dosage (oz) x Conversion factor (mL/oz)

Client dosage (mL) = 2 oz * 29.5735 mL/oz

Client dosage (mL) = 59.147 mL (round to nearest hundredth)

Correct Answer is ["3600"]

Explanation

Here's how to calculate the maximum daily dose of acetaminophen for the child:

Calculate the maximum dose per administration:

Maximum dose per kg per administration = 15 mg/kg (given)

Child's weight = 40 kg (given)

Since this is a PRN medication (given as needed), we will calculate the maximum dose per administration based on the prescribed dosage.

Maximum dose per administration = 15 mg/kg/dose * 40 kg

Maximum dose per administration = 600 mg (round to nearest whole number)

Calculate the number of administrations in a 24-hour period (maximum):

Frequency: Every 4 to 6 hours PRN (given)

Since this is a PRN medication, we will assume the maximum frequency (every 4 hours) for calculating the maximum daily dose.

Number of administrations (maximum) = 24 hours / Frequency (hours/administration)

Number of administrations (maximum) = 24 hours / 4 hours/administration

Number of administrations (maximum) = 6 administrations

Calculate the maximum daily dose:

Maximum daily dose = Maximum dose per administration x Number of administrations (maximum)

Maximum daily dose = 600 mg/administration * 6 administrations

Maximum daily dose = 3600 mg

Therefore, the maximum daily dose the nurse should administer is 3600 mg.

Correct Answer is ["18"]

Explanation

Here's how to calculate the rate (mL/hour) for the infusion pump:

Heparin concentration:

The medication is available in a 250 mL bag containing 20,000 units of heparin.

Heparin concentration (units/mL) = Total heparin (units) / Volume (mL)

Heparin concentration (units/mL) = 20,000 units / 250 mL

Heparin concentration (units/mL) = 80 units/mL (round to nearest whole number)

Prescribed heparin dose: 1,400 units/hour (given)

We need to find the volume delivered per hour (mL/hour) to achieve the prescribed heparin dose (1400 units/hour) considering the concentration (80 units/mL).

Infusion rate (mL/hour) = Dose (units/hour) / Concentration (units/mL)

Infusion rate (mL/hour) = 1400 units/hour / 80 units/mL

Infusion rate (mL/hour) = 17.5 mL/hour (round to nearest whole number)

Therefore, the nurse should program the infusion pump to deliver approximately 18 mL/hour.
