What is the purpose of a hemodynamic monitoring system?
To monitor the client's respiratory status and oxygen saturation
To evaluate the client's renal function and electrolyte balance
To monitor the client's neurological status and intracranial pressure
To measure and assess the client's cardiovascular status and function
The Correct Answer is D
Choice A Reason:
Monitoring the client's respiratory status and oxygen saturation is important but not the primary purpose of a hemodynamic monitoring system. Hemodynamic monitoring focuses on the cardiovascular system, including parameters like cardiac output, stroke volume, and systemic vascular resistance.
Choice B Reason:
Evaluating the client's renal function and electrolyte balance is crucial in overall patient care but is not the main focus of hemodynamic monitoring. Hemodynamic monitoring systems are designed to assess cardiovascular function rather than renal function.
Choice C Reason:
Monitoring the client's neurological status and intracranial pressure is essential in certain clinical situations, such as traumatic brain injury. However, this is not the primary purpose of hemodynamic monitoring, which is centered on cardiovascular assessment.
Choice D Reason:
The primary purpose of a hemodynamic monitoring system is to measure and assess the client's cardiovascular status and function. This includes monitoring parameters such as blood pressure, cardiac output, and tissue perfusion to ensure adequate organ perfusion and guide treatment decisions.

Correct Answer is ["7.2"]
Explanation
Step-by-Step Calculation:
Step 1: Convert the client's weight from pounds to kilograms.
176 lbs ÷ 2.2 = 80 kg
Result = 80 kg
Step 2: Calculate the total dose of dopamine in mcg/min.
3 mcg/kg/min × 80 kg = 240 mcg/min
Result = 240 mcg/min
Step 3: Convert the total dose from mcg/min to mg/min.
240 mcg/min ÷ 1000 = 0.24 mg/min
Result = 0.24 mg/min
Step 4: Determine the concentration of dopamine in mg/mL.
500 mg ÷ 250 mL = 2 mg/mL
Result = 2 mg/mL
Step 5: Calculate the infusion rate in mL/min.
0.24 mg/min ÷ 2 mg/mL = 0.12 mL/min
Result = 0.12 mL/min
Step 6: Convert the infusion rate to mL/hr.
0.12 mL/min × 60 min/hr = 7.2 mL/hr
Result = 7.2 mL/hr
Final Result:
The IV pump should be set to 7.2 mL/hr.
Correct Answer is D
Explanation
Choice A Reason:
Pneumonia is an infection of the lungs, not the ear. It primarily affects the alveoli, causing symptoms like cough, fever, and difficulty breathing. While respiratory infections can sometimes lead to ear infections, pneumonia itself does not directly infect the ear.
Choice B Reason:
Endocarditis is an infection of the inner lining of the heart chambers and valves. It is typically caused by bacteria entering the bloodstream and does not affect the ear. Symptoms include fever, heart murmurs, and fatigue.
Choice C Reason:
Myocarditis is an inflammation of the heart muscle, usually caused by viral infections. It affects the heart's ability to pump blood and does not involve the ear. Symptoms can include chest pain, fatigue, and shortness of breath.
