The healthcare provider prescribes dopamine 2 mcg/kg/min intravenously (IV) for client who weighs 60 kg. The IV bag contains dopamine 200 mg in dextrose 5% in water (DW) 250 mL. The nurse should program the infusion pump to deliver how many mL/hour? (Enter numerical value only.)
The Correct Answer is ["9"]
Here are the steps you can follow to calculate the infusion pump flow rate:
Step 1: Calculate the prescribed dose in mcg/min
- Dose per weight: 2 mcg/kg/min * 60 kg = 120 mcg/min
Step 2: Convert the concentration in the IV bag to mcg/mL
- Convert mg to mcg: 200 mg * 1000 mcg/mg = 200,000 mcg
- Concentration: 200,000 mcg / 250 mL = 800 mcg/mL
Step 3: Calculate the flow rate in mL/min
- Flow rate: 120 mcg/min / 800 mcg/mL = 0.15 mL/min
Step 4: Convert the flow rate to mL/hour
- Hour conversion: 0.15 mL/min * 60 min/hour = 9 mL/hour
Therefore, the nurse should program the infusion pump to deliver 9 mL/hour.

Correct Answer is B
Explanation
After retinal detachment surgery, it is crucial to protect the eye and the surgical repair site from accidental trauma or pressure. Providing an eye shield helps to shield the eye during sleep when the client may not have conscious control over their movements.
This can help prevent inadvertent rubbing or bumping of the eye, which could potentially disrupt the surgical repair and hinder the healing process.
Obtaining vital signs every 2 hours during hospitalization is a routine nursing intervention for postoperative care in general but is not specific to retinal detachment surgery. The frequency of vital sign monitoring may vary depending on the client's overall condition and the healthcare provider's orders.
Teaching a family member to administer eye drops may be necessary for the client's ongoing care, but it is not specifically related to the immediate postoperative period. Eye drop administration instructions can be provided as part of the client's discharge teaching.
Encouraging deep breathing and coughing exercises is a general postoperative intervention that promotes respiratory function and helps prevent complications such as pneumonia. While important for overall postoperative care, it is not specific to retinal detachment surgery.
Correct Answer is C
Explanation
Choice A rationale: Initiating the urine collection without reporting the low serum creatinine is inappropriate. A value of 0.3 mg/dL is below the reference range and may indicate significant muscle wasting or severe malnutrition.
Choice B rationale: Evaluating the BUN level provides information about hydration and renal perfusion, but it does not address the immediate clinical significance of an abnormally low creatinine level in an older adult client.
Choice C rationale: The nurse must notify the provider because a creatinine level of 0.3 mg/dL is abnormally low. In older adults, this often reflects low muscle mass, which significantly impacts how drug dosages are calculated.
Choice D rationale: Assessing for hypokalemia is not directly indicated by a low creatinine level. While electrolyte monitoring is important in drug toxicity, it is not the priority action linked to this specific lab finding.
