An order to start a heparin drip is received from a physician. The order is for 1,000 units heparin per hour. The solution strength is 20,000 units in 500 ml. D5NS. What should the electronic pump be set for?
The Correct Answer is ["25"]
Calculation:
Ordered infusion rate = 1,000 units/hour.
- Identify the available concentration of the solution.
Available concentration = Total units / Total volume
= 20,000 units / 500 mL
= 40 units/mL.
- Calculate the infusion pump setting in milliliters per hour (mL/hr).
Pump setting (mL/hr) = Ordered rate (units/hr) / Available concentration (units/mL)
= 1,000 units/hr / 40 units/mL
= 25 mL/hr.

Correct Answer is ["22.8"]
Explanation
Calculation:
- Calculate the total dose in milligrams (mg) for the client's weight.
Total dose (mg) = Patient weight (kg) x Ordered dose (mg/kg)
= 95 kg x 6 mg/kg
= 570 mg.
Available concentration = 250 mg / 10 mL
= 25 mg/mL.
- Calculate the volume to administer in milliliters (mL).
Volume to administer (mL) = Total dose (mg) / Available concentration (mg/mL)
= 570 mg / 25 mg/mL
= 22.8 mL.
Correct Answer is B
Explanation
A. "The next scheduled nebulizer treatment will be skipped.": Skipping the next treatment without evaluation may compromise airway management. Albuterol is essential for bronchodilation, and withholding it could worsen respiratory distress.
B. "This is an expected side effect, but let me take your pulse.": Anxiety and tremors are common side effects of albuterol due to its beta-adrenergic stimulation. Monitoring the pulse is appropriate since tachycardia is a possible adverse effect requiring close observation.
C. "I will hold the respiratory medication for 24 hours.": Holding albuterol for 24 hours is unsafe, as the client may experience worsening bronchospasm or hypoxemia. Adjustments should only be made with provider guidance, not independently by the nurse.
D. "I will request medication for anxiety from the healthcare provider.": Anxiety in this context is a medication side effect, not a psychiatric condition. Treating it with additional medication is unnecessary when monitoring and reassurance are more appropriate.
