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. APTT of 64 seconds is prolonged but not specific to DIC alone; the normal range is generally around 30-40 seconds, and prolonged APTT can be seen in various conditions.
B. A fibrinogen level of 85 mg/dL is low. In DIC, fibrinogen levels decrease due to increased clotting and subsequent consumption of clotting factors.
C. A platelet count of 156,000/mm³ is within the normal range for most clients (150,000-450,000/mm³), though it might be lower in acute DIC.
D. A PT of 12 seconds is within the normal range for most clients (11-13.5 seconds), so it does not require reporting for DIC.
Correct Answer is A
Explanation
A. Nosebleeds (epistaxis) are a common adverse effect of bevacizumab, as it can cause bleeding due to its anti-angiogenic properties.
B. Temporary loss of smell is not a recognized adverse effect of bevacizumab.
C. Weight gain is not typically associated with bevacizumab treatment.
D. Mild hearing loss is not a common adverse effect of bevacizumab.
