A client is currently receiving an infusion labeled Heparin Sodium 25,000 Units in 5% Dextrose Injection 500 mL at 14 ml/hour. A prescription is received to change the rate of the Infusion to 900 units of heparin per hour. The nurse should set the infusion pump to deliver how many mL/hour? (Enter numeric value only.)
The Correct Answer is ["18"]
First, we need to find the concentration of Heparin per milliliter in the current infusion. We can do this by dividing the total number of Heparin units by the total volume of the infusion:
Heparin concentration (units/mL) = Total Heparin units / Total volume (mL) Heparin concentration = 25,000 units / 500 mL
Heparin concentration = 50 units/mL
Now, we know the desired rate of Heparin delivery (900 units/hour) and the concentration of Heparin per milliliter (50 units/mL). We can use this information to calculate the required flow rate in milliliters per hour:
Flow rate (mL/hour) = Desired Heparin rate (units/hour) / Heparin concentration (units/mL)
Flow rate = 900 units/hour / 50 units/mL Flow rate = 18 mL/hour
Therefore, the nurse should set the infusion pump to deliver 18 mL/hour.

Correct Answer is D
Explanation
A. "How do you cope with the voices?" is an important question to assess the client's coping mechanisms, but it does not provide direct information about the content or nature of the auditory hallucinations. While coping strategies are relevant, understanding the nature of the hallucinations is crucial for treatment planning.
B. "When do you hear voices?" is important to understand the timing and frequency of the hallucinations, but it does not provide information about the content or nature of the hallucinations themselves.
C. "Which medication works best?" is important to assess the client's previous treatment history and response to medication, but it does not directly address the current assessment of the auditory hallucinations.
D. "What are the voices saying?" is the most important question because it directly addresses the content and nature of the auditory hallucinations. Understanding the specific content, tone, and perceived significance of the voices can provide valuable information for diagnosis, treatment planning, and assessing the client's level of distress or impairment.
Correct Answer is C
Explanation
A. Core strengthening. While important for overall health, core strengthening is not as directly effective for osteoporosis prevention as weight-bearing exercise.
B. Aerobic exercise. Aerobic exercise is beneficial for cardiovascular health but does not have the same bone-strengthening effect as weight-bearing exercise.
C. Weight-bearing exercise. Weight-bearing exercises, such as walking, jogging, and strength training, are essential for maintaining bone density and preventing osteoporosis.
D. Muscle stretching and toning. Stretching and toning are important for flexibility and muscle health but do not significantly impact bone density compared to weight-bearing exercises.
