Dopamine 5 mcg/kg/minute IV is prescribed for a client who weighs 132 pounds. The pharmacy dispenses a 500 mL IV solution of 0.9% normal saline with dopamine 1600 mg. The nurse should program the infusion pump to deliver how many ml/hour? (Enter numeric value only. If rounding is required, round to the nearest tenth)
The Correct Answer is ["5.6"]
Convert pounds to kg 1kg= 2.2 pounds 132pounds= 132/2.2=60kg
Desired dose per minute= 5 mcg/kg= 560=300mcg/min Desired dose per hour= 300mcg60mins= 18000mcg Available dose= 1600mg/500ml
1mg=1000mcg
Available dose = 1600000mcg/500ml Infusion rate:
1600000mcg=500ml 18000mcg=18000500/1600000
= 5.625 mL/hour
Rounded to the nearest tenth: 5.6 ml/hour

Correct Answer is ["A","B","C","D"]
Explanation
A. The tube should be flushed with at least 15–30 mL of water before, between, and after medication administration to prevent clogging and ensure full delivery of the medications.
B. Instructing the nurse to administer each medication separately is correct. This is important to prevent drug interactions within the tube and to ensure accurate dosing. Administering
medications separately allows for proper absorption and can prevent complications such as clogging of the tube.
C. Adding the liquid volumes when documenting fluid intake is correct. It is essential to account for all sources of fluid intake to maintain accurate fluid balance records. Medications
administered through a gastrostomy tube contribute to the patient's overall fluid intake and must be included in the documentation.
D. Confirming that the nurse determined the amount of gastric residual is correct. This is a critical step to ensure that the patient is tolerating the feedings and to prevent complications such as
aspiration. Gastric residual volume can indicate if the patient's digestive system is processing the feeding appropriately.
E. Advising the nurse to use the plunger when giving medications is not necessary in this context. The use of a plunger can be appropriate in some situations, but the scenario does not provide enough information to suggest that the nurse had difficulty administering the medications that would require the use of a plunger. Additionally, using a plunger can increase the risk of tube
damage or patient discomfort.
Correct Answer is ["E","F"]
Explanation
A. Suctioning the client to clear the airway is not directly related to the administration of morphine and is typically not a routine precaution unless the patient has a specific need.
B. Using soft restraints is not a standard safety measure for morphine administration and could be considered if the patient has a history of confusion or agitation, but there is no such indication in this scenario.
C. Performing a 12-lead electrocardiogram is not a standard procedure for ensuring the safe administration of morphine and is usually done for cardiac assessment.
D. Having a manual resuscitation bag at the bedside is a good practice in case of an emergency but is not specific to morphine administration safety.
E. Asking the client about other medications she takes is crucial to prevent drug interactions, as morphine can interact with many medications, potentially leading to adverse effects.
F. Taking an initial respiratory rate is important because morphine can cause respiratory depression, and it is essential to have a baseline to monitor for any changes after administration.
