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
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.

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.

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.
