A nurse is providing care for a client experiencing obstructive shock. Which of the following diagnoses should the nurse expect?

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.

A. A client who has coronary artery disease (CAD) and Bell's palsy: Bell's palsy, a condition characterized by sudden, temporary weakness or paralysis of the facial muscles, does not directly increase the risk of complications following CABG surgery. While Bell's palsy may affect facial muscle function, it typically does not impact respiratory function or cardiovascular stability during surgery.

B. A client who has coronary artery disease (CAD) and chronic diverticulitis: Chronic diverticulitis, inflammation or infection of the diverticula in the colon, is not directly related to increased risk for complications following CABG surgery. While diverticulitis may require medical management and dietary modifications, it does not typically affect cardiovascular or respiratory function during surgery.

C. A client who has coronary artery disease (CAD) and chronic allergies: Chronic allergies, while they may cause respiratory symptoms such as nasal congestion or rhinitis, are not typically associated with increased risk for complications following CABG surgery. Allergies alone are unlikely to significantly impact cardiovascular stability or respiratory function during surgery compared to conditions such as COPD.

D. A client who has coronary artery disease (CAD) and chronic obstructive pulmonary disease (COPD): A client with CAD and COPD is at the highest risk for complications following coronary artery bypass graft (CABG) surgery. COPD is a chronic respiratory condition characterized by airflow limitation and increased airway resistance, often accompanied by emphysema and chronic bronchitis. These respiratory impairments can significantly impact the client's ability to tolerate anesthesia, mechanical ventilation, and postoperative respiratory function. COPD increases the risk of complications such as atelectasis, pneumonia, exacerbation of COPD, and respiratory failure following CABG surgery.
