A client weighing 198 lbs is prescribed Dopamine hydrochloride IV at 2 mcg/kg/minute to promote renal perfusion.

The pharmacy provides a pre-mixed bag of dopamine containing 400 mg in 250 mL dextrose 5% in water (D5W). An IV pump that provides a precision infusion rate to a tenth of a mL is available.

How many mL/hour should the IV pump be set to deliver? (Enter numeric value only. If rounding is required, round to the nearest tenth.)

Answer and Explanation

The Correct Answer is ["6.8"]

Step 1: Convert the client’s weight from lbs to kg. 1 kg is approximately 2.2 lbs. So, 198 lbs ÷

2.2 = 90 kg (rounded to the nearest whole number).

Step 2: Calculate the total mcg of Dopamine needed per minute. The prescription is for 2 mcg/kg/minute. So, 90 kg × 2 mcg/kg/minute = 180 mcg/minute.

Step 3: Convert the total mcg of Dopamine in the bag to mcg/mL. The bag contains 400 mg of Dopamine in 250 mL. 1 mg is equal to 1000 mcg. So, 400 mg × 1000 = 400,000 mcg. Therefore, the concentration is 400,000 mcg ÷ 250 mL = 1600 mcg/mL.

Step 4: Calculate the mL of Dopamine needed per minute. So, 180 mcg/minute ÷ 1600 mcg/mL

= 0.1125 mL/minute.

Step 5: Convert mL/minute to mL/hour. There are 60 minutes in an hour. So, 0.1125 mL/minute × 60 = 6.75 mL/hour. The IV pump should be set to deliver 6.8 mL/hour (rounded to the nearest tenth).

Correct Answer is A

Explanation

Choice A rationale
Given the client’s risk factors of poor wound healing, decreased bone density, and increased capillary fragility, the most appropriate outcome statement to include in the plan of care is that the client implements measures to prevent injury. This includes avoiding falls, using caution with sharp objects to prevent cuts, and taking steps to protect the bones.
Choice B rationale
While it is important for the client to understand their disease and ways to control it, this is not the most appropriate outcome statement given the client’s specific risk factors.
Choice C rationale
Improving body image may be a relevant goal for some clients with Cushing’s syndrome, but it is not the most appropriate outcome statement given the client’s specific risk factors.
Choice D rationale
Experiencing a normal fluid balance may be a relevant goal for some clients with Cushing’s syndrome, but it is not the most appropriate outcome statement given the client’s specific risk factors.

A. Keep the head of the bed raised 45 degrees. B. Monitor the patient’s blood glucose level. C. Assess the warmth of the patient’s extremities. D. Maintain strict intake and output.

Correct Answer is D

Explanation

Choice A rationale

Keeping the head of the bed raised 45 degrees can help improve lung expansion and reduce the risk of aspiration, which is particularly important for patients who are intubated or receiving enteral nutrition. However, it is not the most important intervention for a patient with septic shock.
Choice B rationale
Monitoring the patient’s blood glucose level is important, especially if the patient is receiving insulin or parenteral nutrition, as these can increase blood glucose levels. However, it is not the most important intervention for a patient with septic shock.
Choice C rationale
Assessing the warmth of the patient’s extremities can provide information about peripheral perfusion and may be useful in monitoring the patient’s response to treatment. However, it is not the most important intervention for a patient with septic shock.
Choice D rationale
This is the correct answer. Maintaining strict intake and output is crucial in managing a patient with septic shock. Fluid balance is a key component of managing septic shock, and accurate intake and output measurements are essential for guiding fluid resuscitation and assessing the patient’s response to treatment.
