A client receives a prescription for 1 liter of lactated Ringer's intravenously (IV) to be infused over 8 hours. The IV administration set delivers 20 gtt/mL. How many gtt/min should the nurse regulate the infusion? (Enter numerical value only. If rounding is required, round to the nearest whole number.)

Answer and Explanation

The Correct Answer is ["42"]

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

(gtt/min) = (mL/hour) x (gtt/mL) / 60

Substituting the given values, we get:

(gtt/min) = (1000 / 8) x (20) / 60

Simplifying, we get:

(gtt/min) = 125 x 20 / 60

(gtt/min) = 41.667

(rounded gtt/min) = 42

Therefore, the nurse should regulate the infusion to deliver 42 gtt/minute of lactated Ringer's.

Correct Answer is ["1200"]

Explanation

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

(units of heparin) = (mL/hour) x (hours) x (units per mL)

Substituting the given values, we get:

(units of heparin) = (25) x (12) x (20,000 / 500)

Simplifying, we get:

(units of heparin) = (25) x (12) x (40)

(units of heparin) = 1200

Therefore, the client should receive 1200 units of heparin in 12 hours.

Correct Answer is ["1.2"]

Explanation

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

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

- Calculate the dose of enoxaparin in mg per administration by multiplying the weight in kg by the dosage in mg/kg

- Divide the dose in mg per administration by the concentration of enoxaparin in the prefilled syringe in mg/mL

- Multiply the volume in mL per administration by the number of administrations per day

- Round the result to the nearest tenth

Using these steps, we get:

- (weight in kg) = (132) / (2.2) = 60 kg

- (dose in mg per administration) = (1) x (60) = 60 mg

- (volume in mL per administration) = (60) / (60 / 0.6) = 0.6 mL

- (volume in mL per day) = (0.6) x (2) = 1.2 mL

- (rounded volume in mL per day) = 1.2 mL

Therefore, the nurse should administer 1.2 mL of enoxaparin per day.
