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.
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 C
Explanation
Choice A rationale:
The client with epidural analgesia and weakness in the lower extremities might be experiencing complications related to the epidural, such as epidural hematoma or nerve damage. However, the immediate concern is the client with a hip fracture and new onset of tachypnea. Tachypnea can indicate a pulmonary embolism or worsening respiratory status due to the fracture, both of which require urgent assessment and intervention.
Choice B rationale:
The client with diabetes mellitus and an HbA1c of 6.89% has a well-controlled blood glucose level. This condition does not require immediate attention compared to the client with a hip fracture and tachypnea, who might be experiencing a life-threatening complication.
Choice C rationale:
The client with a hip fracture and new onset of tachypnea is the priority for assessment. Tachypnea can be a sign of respiratory distress, which could indicate a pulmonary embolism or worsening lung function due to the fracture. Timely intervention is crucial to prevent further complications.
Choice D rationale:
The client with sinus arrhythmia and cardiac monitoring is stable and does not require immediate attention compared to the client with a hip fracture and tachypnea.
Correct Answer is D
Explanation
Choice A rationale:
Asking about past coping mechanisms can provide valuable information, but in this situation, where the client is expressing thoughts of hopelessness, it's crucial to assess the immediate risk of suicide. Therefore, this choice is not the best option in this context.
Choice B rationale:
Involving significant others in the client's care is important, but it doesn't address the client's current emotional state and suicidal ideation. This choice does not take priority in this scenario.
Choice C rationale:
While exploring family history, including suicide, is relevant, it's not the first question to ask. Assessing the client's current thoughts and feelings should be the priority before delving into family history. Therefore, this choice is not the best option at this moment.
Choice D rationale:
(Correct Choice) This is the most appropriate question to ask first. Assessing the client's suicidal ideation is crucial for ensuring their safety. If the client expresses suicidal thoughts, the nurse can take immediate steps to keep the client safe, such as involving a mental health professional or initiating a suicide risk assessment.
