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.

D. Hypotension is not a typical manifestation of increased intracranial pressure; increased ICP more commonly leads to hypertension.
Correct Answer is B
Explanation
A. First-degree AV block shows a prolonged PR interval but not necessarily an irregular heart rate or a significant pulse deficit.

C. Sinus tachycardia presents with a rapid but regular heart rate, not irregular palpitations.
D. Sinus bradycardia shows a slow heart rate and is not associated with an irregular heart rate or significant pulse deficit.
