CCRN-Adult Exam Dumps and Practice Questions

Pulsus paradoxus is defined as a decrease in systolic blood pressure (BP) of more than 10 mm Hg during normal inspiration. This phenomenon occurs due to the increased negative intrathoracic pressure during inspiration, which exaggerates the normal drop in systolic BP. It is often seen in conditions such as cardiac tamponade, constrictive pericarditis, and severe asthma or COPD exacerbations.

The best response is to assess the patient's feelings and understanding of their condition and prognosis. This response opens a dialogue and allows the nurse to provide education and emotional support based on the patient's specific concerns. Other responses may provide false reassurance or imply assumptions about the patient's future without first understanding their current emotional state and concerns.

For a patient with a Stage III pressure ulcer, a serum albumin level of 2.1 mg/dL is most concerning because it indicates severe hypoalbuminemia, which is associated with poor nutritional status and delayed wound healing. Adequate nutrition, particularly protein intake, is crucial for wound healing. The other lab results, while not ideal, are less immediately critical in the context of pressure ulcer healing.

Shortness of breath is a sign of respiratory distress that may indicate a serious complication of acute pancreatitis, such as pleural effusion, atelectasis, or acute respiratory distress syndrome (ARDS). These conditions can impair oxygenation and ventilation, and may require supplemental oxygen or mechanical ventilation. The provider should be notified immediately if the patient has shortness of breath, as well as other signs of respiratory distress, such as cyanosis, tachypnea, or use of accessory muscles12. Hypoactive bowel sounds, hyperglycemia, and vomiting are common findings in acute pancreatitis, but they are not as urgent as shortness of breath. They may indicate paralytic ileus, pancreatic insufficiency, or gastric outlet obstruction, respectively. These conditions can be managed with supportive measures, such as intravenous fluids, antiemetics, analgesics, and nutritional support3 .

Acute peripheral arterial insufficiency typically presents with sudden, severe pain at rest, which may be accompanied by other signs such as pallor, paresthesia, paralysis, pulselessness, and poikilothermia (the six P's). This condition indicates a critical reduction in blood flow to the affected extremity, requiring immediate medical attention.
