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.

Correct Answer is B
Explanation
A. Atelectasis is incorrect. Atelectasis refers to lung collapse, which presents as reduced breath sounds and hypoxemia, not abnormal chest movement during respiration.
B. Flail chest is correct. Flail chest is characterized by paradoxical chest movement where a segment of the chest wall moves inward during inspiration and outward during expiration.
C. Pneumothorax is incorrect. Pneumothorax would cause sudden chest pain and dyspnea, but does not cause paradoxical chest movement.
D. Hemothorax is incorrect. Hemothorax involves blood in the pleural space and would cause reduced breath sounds and signs of shock, but not paradoxical chest movement.
Correct Answer is D
Explanation
A. Carvedilol does not significantly increase the risk of rhabdomyolysis when used with colchicine.
B. Omeprazole does not interact with colchicine in a way that increases the risk of rhabdomyolysis.
C. Hydrochlorothiazide does not have a known interaction with colchicine that significantly increases the risk of rhabdomyolysis.
D. Atorvastatin increases the risk of rhabdomyolysis when used with colchicine, as both can contribute to muscle damage.
