A nurse is assessing for paradoxical blood pressure on a client who has constrictive pericarditis. Which of the following findings should the nurse expect?

Apical pulse rate is different than the radial pulse rate

Drop in systolic BP by 20 mm Hg when changing positions

Increase in heart rate by 20% when moving from sitting to standing

Decrease in systolic pressure by more than 10 mm Hg during inspiration

Answer and Explanation

The Correct Answer is D

A. A difference between the apical pulse rate and the radial pulse rate is more indicative of a pulse deficit, which is not specific to constrictive pericarditis.
B. A drop in systolic blood pressure by 20 mm Hg when changing positions describes orthostatic hypotension, not paradoxical blood pressure.
C. An increase in heart rate when moving from sitting to standing reflects orthostatic changes, not paradoxical blood pressure.
D. Paradoxical blood pressure refers to a decrease in systolic blood pressure of more than 10 mm Hg during inspiration, which can occur in constrictive pericarditis due to impaired filling of the heart during diastole.

Correct Answer is ["100"]

Explanation

- First, calculate the total volume to be infused over the desired time frame: 50 mL over 30 minutes.

- To find the rate in mL/hr, multiply the volume by 2 (since 30 minutes is half an hour), resulting in 100 mL/hr.

- Therefore, the nurse should set the IV pump to deliver 100 mL/hr to administer clindamycin 300 mg over 30 minutes.

A. Side-lying B. Supine C. High-Fowler's D. Leaning forward

Correct Answer is C

Explanation

A. The side-lying position is not appropriate for paracentesis because it does not allow optimal access to the abdomen and can make fluid removal more difficult.

B. The supine position is also not suitable for paracentesis, as it may not allow for proper drainage and can increase the risk of respiratory compromise, especially in clients with large volumes of ascitic fluid.

C. High-Fowler’s position is correct because it helps pool the ascitic fluid in the lower abdomen, making it easier to access and drain during the procedure. This position also helps improve breathing by relieving pressure on the diaphragm caused by the ascites.

D. The leaning forward position is not appropriate for paracentesis, as it can be uncomfortable and does not provide optimal access to the abdominal cavity for fluid removal.
