A nurse is preparing to administer dopamine hydrochloride 4 mcg/kg/min via continuous infusion.

Available is dopamine hydrochloride in a solution of 800 mg in a 250 mL bag.

The client weighs 80 kg. The nurse should set the IV infusion to deliver how many mL/hr? (Round the answer to the nearest whole number.

Use a leading zero if it applies.)

4 mL/hr.

5 mL/hr.

6 mL/hr.

7 mL/hr.

Answer and Explanation

The Correct Answer is C

Step 1: Convert the dopamine hydrochloride dose from mcg to mg. We know that 1 mg = 1000 mcg. So, 4 mcg = 0.004 mg.

Step 2: Calculate the total amount of dopamine hydrochloride the client needs per minute. We know that the client weighs 80 kg and the dose is 0.004 mg/kg/min. So, 0.004 mg/kg/min × 80 kg = 0.32 mg/min.

Step 3: Convert the total amount of dopamine hydrochloride the client needs per minute to an hourly rate. We know that 1 hour = 60 minutes. So, 0.32 mg/min × 60 min/hr = 19.2 mg/hr.

Step 4: Calculate the volume of the solution that contains 19.2 mg of dopamine hydrochloride. We know that the solution contains 800 mg in 250 mL. So, (19.2 mg ÷ 800 mg) × 250 mL = 6 mL.

Therefore, the nurse should set the IV infusion to deliver 6 mL/hr (rounded to the nearest whole number).

Correct Answer is D

Explanation

The correct answer is choice d. Privately interview the client about the injuries.

Choice A rationale:

Contacting the family regarding the client’s condition might not be appropriate if the family is suspected of being involved in the abuse. It could potentially put the client at further risk.

Choice B rationale:

Notifying risk management is important for documentation and internal review, but it does not directly address the immediate need to assess and ensure the client’s safety.

Choice C rationale:

Informing the transferring agency of the client’s condition is necessary for continuity of care, but it does not address the immediate need to investigate the cause of the injuries and ensure the client’s safety.

Choice D rationale:

Privately interviewing the client about the injuries allows the nurse to gather more information about the cause of the injuries in a safe and confidential manner. This step is crucial in assessing the situation and determining if further action, such as reporting to authorities, is needed. It ensures the client’s safety and helps in identifying any potential abuse.

A. Heart rate 58/min. B. Fasting blood glucose 100 mg/dL. C. WBC count 2,900/mm3. D. Hgb 14 g/dL.

Correct Answer is C

Explanation

Choice A rationale:

Heart rate 58/min. Clozapine, an atypical antipsychotic medication, can cause bradycardia (slow heart rate) as a side effect. However, the heart rate of 58/min is within the normal range for adults, so it is not a contraindication for clozapine administration.

Choice B rationale:

Fasting blood glucose 100 mg/dL. A fasting blood glucose level of 100 mg/dL is within the normal range (70-99 mg/dL) for adults. It is not a contraindication for clozapine administration.

Choice C rationale:

WBC count 2,900/mm3. Clozapine can cause agranulocytosis, a severe reduction in white blood cell (WBC) count, which can lead to increased susceptibility to infections. A WBC count of 2,900/mm3 is significantly below the normal range (4,000-11,000/mm3) and is a contraindication for clozapine administration due to the risk of severe immunosuppression.

Choice D rationale:

Hgb 14 g/dL. Hemoglobin (Hgb) level of 14 g/dL is within the normal range for adult males (13.8-17.2 g/dL) and females (12.1-15.1 g/dL). It is not a contraindication for clozapine administration.
