A nurse is assessing a client suspected of having cardiac tamponade. Which of the following findings indicates the presence of pulsus paradoxus?

A decrease in systolic blood pressure greater than 10 mm Hg during inspiration

A decrease in heart rate greater than 10/min when lying down

An increase in diastolic blood pressure greater than 10 mm Hg during inspiration

An increase in heart rate greater than 20/min when standing

Answer and Explanation

The Correct Answer is A

A. A decrease in systolic blood pressure greater than 10 mm Hg during inspiration: Pulsus paradoxus is an exaggerated decrease in systolic blood pressure during inspiration. Normally, there is a slight decrease in systolic blood pressure during inspiration due to increased intrathoracic pressure and decreased venous return to the heart. However, in conditions such as cardiac tamponade or severe asthma exacerbations, the decrease in systolic blood pressure during inspiration is more pronounced (>10 mm Hg), indicating impaired cardiac output and decreased left ventricular filling during inspiration.

B. A decrease in heart rate greater than 10/min when lying down: This finding is not indicative of pulsus paradoxus. Pulsus paradoxus primarily refers to changes in systolic blood pressure during inspiration rather than alterations in heart rate when lying down.

C. An increase in diastolic blood pressure greater than 10 mm Hg during inspiration: This finding is not indicative of pulsus paradoxus. Pulsus paradoxus is characterized by an exaggerated decrease in systolic blood pressure during inspiration, not changes in diastolic blood pressure.

D. An increase in heart rate greater than 20/min when standing: This finding is not indicative of pulsus paradoxus. Pulsus paradoxus primarily refers to changes in systolic blood pressure during inspiration rather than alterations in heart rate when standing.

Correct Answer is D

Explanation

A. Stress can contribute to the development of atrial flutter, but it is not the highest risk factor compared to other options.

B. While electrolyte imbalances resulting from vomiting and diarrhea can predispose someone to arrhythmias, they are not as significant a risk factor for atrial flutter as other conditions.

C. A family history of atrial flutter may increase the likelihood of developing the condition, but it is not as significant a risk factor compared to other options.

D. A history of myocardial infarction and stent placement indicates underlying heart disease, which is a significant risk factor for developing atrial flutter. Cardiac events like myocardial infarction can lead to structural changes in the heart, such as scarring or remodeling, which can predispose individuals to atrial flutter. Therefore, this client is at the highest risk for developing atrial flutter among the options provided.

A. Intermittent pneumatic compression pumps B. Ankle-brachial index test C. Layered wraps D. Elevation of legs E. Exercise

Correct Answer is ["A","C","D","E"]

Explanation

A. Intermittent pneumatic compression pumps: Intermittent pneumatic compression pumps can help improve circulation in the lower extremities by assisting with venous return. These devices inflate and deflate sequentially, promoting venous blood flow and reducing edema in clients with peripheral venous disease.

B. Ankle-brachial index test: The ankle-brachial index (ABI) test is a non-invasive vascular study used to assess peripheral arterial disease (PAD). It compares the blood pressure in the ankle with the blood pressure in the arm to evaluate arterial circulation.

C. Layered wraps: Layered wraps, such as compression bandages or stockings, are typically used in the management of venous insufficiency and venous ulcers. They are not as commonly utilized in peripheral venous disease, however, they may be beneficial for some clients with PVD.

D. Elevation of legs: Elevating the legs above the level of the heart can help reduce edema and improve venous return in clients with peripheral venous disease. Gravity assists in draining blood from the lower extremities back toward the heart, thereby reducing swelling and discomfort.

E. Exercise: Regular physical activity, particularly lower extremity exercises such as walking, can promote venous return and improve circulation in clients with peripheral venous disease. Exercise helps to pump blood back to the heart, reducing venous stasis and the risk of complications such as venous thrombosis.
