The nurse is initiating a 500 mL IV of normal saline at 60 mL/hour for a client with heart failure. How many hours should the IV infuse? (Enter numeric value only. If rounding is required, round to the nearest tenth.)

Answer and Explanation

The Correct Answer is ["8.3"]

The correct answer is 8.3 hours. To find the answer, we can use the following formula:

(hours) = (mL of IV) / (mL/hour)

Substituting the given values, we get:

(hours) = (500) / (60)

Simplifying, we get:

(hours) = 8.333

(rounded hours) = 8.3

Therefore, the IV should infuse for 8.3 hours.

Correct Answer is ["10 "]

Explanation

To find the answer, we can use the following steps:

- Convert the child's weight from pounds to kilograms by dividing by 2.2

- Multiply the weight in kilograms by the dosage in mg/kg

- Round the result to the nearest whole number

Using these steps, we get:

- (weight in kg) = (35) / (2.2) = 15.909

- (dose in mg) = (0.6) x (15.909) = 9.545

- (rounded dose in mg) = 10

Therefore, the nurse should administer 10 mg of dexamethasone to the child.

Correct Answer is ["15"]

Explanation

To find the answer, we can use the following steps:

- Convert the child's weight from pounds to kilograms by dividing by 2.2

- Calculate the total daily dose of amoxicillin in mg by multiplying the weight in kg by the dosage in mg/kg/day

- Divide the total daily dose of amoxicillin in mg by the number of doses per day to get the dose per administration

- Divide the dose per administration in mg by the concentration of amoxicillin in mg/mL

- Round the result to the nearest whole number

Using these steps, we get:

- (weight in kg) = (66) / (2.2) = 30 kg

- (total daily dose in mg) = (80) x (30) = 2400 mg

- (dose per administration in mg) = (2400) / (2) = 1200 mg

- (volume per administration in mL) = (1200) / (400 / 5) = 15 mL

- (rounded volume per administration in mL) = 15 mL

Therefore, the nurse should administer 15 mL of amoxicillin oral suspension with each dose.
