A nurse in a critical care unit is caring for a client who suffered a knife wound to the chest. The nurse suspects the client is developing cardiac tamponade. Which of the following assessment findings should the nurse identify as supporting this suspicion?

Choice A Reason: This is incorrect because preparing for mechanical ventilation is not the priority nursing intervention, as it is an invasive and potentially harmful procedure that should be reserved for clients who have severe respiratory failure and cannot maintain adequate oxygenation with noninvasive methods.

Choice B Reason: This is correct because administering oxygen via face mask is the priority nursing intervention, as it is a noninvasive and effective way to improve oxygenation and reduce hypoxemia in a client who has low PaO2 and SaO2. Oxygen therapy can also decrease the workload of the heart and lungs and prevent further complications.

Choice C Reason: This is incorrect because preparing to administer a sedative is not the priority nursing intervention, as it may worsen the client's respiratory status and mask the signs and symptoms of hypoxemia. Sedatives should be used with caution and only after oxygenation has been optimized.

Choice D Reason: This is incorrect because assessing for indications of pulmonary embolism is not the priority nursing intervention, as it is a diagnostic rather than a therapeutic action. Pulmonary embolism is a possible cause of the client's condition, but it does not address the immediate problem of hypoxemia.

Choice A Reason: This choice is incorrect because urinary hesitancy is not the priority finding for the nurse to address.

Urinary hesitancy is a difficulty or delay in starting or maintaining a urine stream. It may be caused by various factors such as prostate enlargement, urinary tract infection, medication side effects, or psychological issues. It may cause discomfort, pain, or urinary retention, but it does not pose an immediate threat to the client's life.

ChoiceB Reason: This choice is correct because dysphagia is the priority finding for the nurse to address. Dysphagia is a difficulty or inability to swallow food or liquids. It may be caused by various factors such as stroke, Parkinson's disease, dementia, esophageal cancer, or oral infections. It may cause malnutrition, dehydration, aspiration, or choking, which can lead to serious complications such as pneumonia, sepsis, or death. Therefore, the nurse should assess the client's swallowing function and provide appropriate interventions such as modifying the diet texture, using thickening agents, or teaching swallowing techniques.

ChoiceC Reason: This choice is incorrect because swollen gums are not the priority finding for the nurse to address. Swollen gums are an inflammation or enlargement of the gingival tissue that surrounds the teeth. They may be caused by various factors such as poor oral hygiene, gum disease, vitamin deficiency, medication side effects, or hormonal changes. They may cause bleeding, pain, or infection, but they do not pose an immediate threat to the client's life.

Choice D Reason: This choice is incorrect because pruritus is not the priority finding for the nurse to address. Pruritus is a sensation of itching that affects the skin. It may be caused by various factors such as dry skin, allergies, eczema, psoriasis, liver disease, or kidney disease. It may cause discomfort, scratching, or skin damage, but it does not pose an immediate threat to the client's life.
