A nurse is caring for a client is who has a deep vein thrombosis and is prescribed heparin by continuous IV infusion at 1,200 units/hr. Available is heparin 25,000 units in 500 mL D5W. The nurse should set the IV pump to deliver how many mL/hr? (Round the answer to the nearest tenth/whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["24"]

- First, determine the concentration of the heparin solution. In this case, it's 25,000 units in 500 mL, which means there are 50 units per mL.

- Next, calculate the required rate to deliver 1,200 units per hour. Since the concentration is 50 units per mL, divide 1,200 units by 50 units/mL to find the required mL per hour.

- The calculation will be 1,200 units/hr ÷ 50 units/mL = 24 mL/hr.

- Since the question asks to round to the nearest tenth or whole number, and the result is a whole number, the IV pump should be set to deliver 24.0 mL/hr.

Answer =24

Correct Answer is B

Explanation

A. Coffee has not been shown to significantly increase the risk of gout attacks and may even have a protective effect due to its antioxidant properties.

B. Alcohol, especially beer and spirits, can trigger gout attacks by increasing the level of uric acid in the blood. Alcohol consumption should be limited or avoided to reduce the risk of gout flare-ups.

C. Milk and other low-fat dairy products are actually recommended for people with gout, as they may help lower uric acid levels.

D. Orange juice, while high in vitamin C, does contain fructose, which can increase uric acid production. However, it is not as significant a trigger as alcohol. Moderation is key.

A. The client is experiencing premature atrial contractions. B. The client has bilateral wheezes. C. The client has a decreased oxygen saturation level. D. The client has lower leg edema.

Correct Answer is A

Explanation

A. The client is experiencing premature atrial contractions is correct. Premature atrial contractions can interfere with pulse pressure analysis and affect the accuracy of cardiac output measurements.

B. The client has bilateral wheezes is incorrect. Wheezes affect lung function, not directly the accuracy of pulse pressure analysis for cardiac output.

C. The client has a decreased oxygen saturation level is incorrect. While it is a concern, it does not compromise pulse pressure readings directly.

D. The client has lower leg edema is incorrect. Edema affects peripheral circulation but does not directly compromise pulse pressure measurements for cardiac output.
