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 ["C","D"]

Explanation

A. Modern pacemakers are designed to withstand interference from microwave ovens, so it is not necessary to avoid having them in the home.

C. Monitoring the pulse daily helps to ensure the pacemaker is functioning properly and to detect any irregularities early.
D. Wearing tight clothing over the insertion area can cause discomfort and may interfere with the function of the pacemaker.
E. Activities that involve jolting or the risk of impact to the pacemaker should be avoided until cleared by a healthcare provider, and this period may extend beyond 4 weeks.

Explanation

A. Keeping the leg in a dependent position can increase swelling; the leg should be elevated to reduce swelling.
B. Applying ice to the affected area is recommended to reduce swelling and pain after arthroscopic knee surgery.
C. Active range of motion exercises might be recommended, but this depends on the surgeon’s instructions and typically starts after the initial recovery period.
