A nurse is preparing to administer heparin 5,000 units subcutaneous to a client who is postpartum. Available is heparin solution for injection 10,000 units/mL. After validating the dosage with another nurse. how many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.5"]
To calculate the correct dosage of heparin, the nurse needs to use the formula: (desired dose ÷ available concentration) = volume to administer. In this case, the desired dose is 5,000 units, and the available concentration is 10,000 units per mL. Therefore, the calculation would be: (5,000 units ÷ 10,000 units/mL) = 0.5 mL. So, the nurse should administer 0.5 mL of heparin to the client. This dosage should be validated with another nurse to ensure accuracy and safety for the client.

Correct Answer is ["1.7"]
Explanation
To calculate the IV pump setting, first determine the total micrograms of dopamine needed per minute for the newborn: 5 mcg/kg/min * 4.4 kg = 22 mcg/min. Next, convert the available dopamine concentration to micrograms: 200 mg * 1000 mcg/mg = 200,000 mcg. Now, calculate how many micrograms are in each mL of the solution: 200,000 mcg / 250 mL = 800 mcg/mL. Then, determine how many mL are needed per minute to deliver the required 22 mcg/min: 22 mcg/min / 800 mcg/mL = 0.0275 mL/min. Finally, convert this to an hourly rate: 0.0275 mL/min * 60 min/hr = 1.65 mL/hr. Rounded to the nearest tenth, the IV pump should be set to deliver 1.7 mL/hr.
Correct Answer is ["0.75"]
Explanation
To administer the correct dose of enoxaparin, which is 75 mg, when the available injection concentration is 100 mg/mL, the nurse needs to calculate the volume of enoxaparin to be administered. The calculation is based on the formula: Volume = Dose / Concentration. So, for a dose of 75 mg and a concentration of 100 mg/mL, the calculation would be 75 mg / 100 mg/mL = 0.75 mL.
