A nurse in the ICU is caring for a client who has heart failure and is receiving a dobutamine drip. The nurse should identify that which of the following findings indicates that the medication is effective?
Increased urine output
Decreased blood glucose level
Decreased blood pressure
Increased heart rate
The Correct Answer is A
Choice A Reason: Dobutamine is a positive inotropic agent that increases the contractility of the heart and improves cardiac output. This leads to increased renal perfusion and urine output, which reduces the fluid overload and edema associated with heart failure. Therefore, this choice is correct.
Choice B Reason: Dobutamine does not have a direct effect on blood glucose level. It may cause hyperglycemia as a side effect, but this is not an indication of its effectiveness. Therefore, this choice is incorrect.
Choice C Reason: Dobutamine may cause a slight decrease in blood pressure due to vasodilation, but this is not its main therapeutic effect. A significant decrease in blood pressure may indicate hypovolemia, hypotension, or shock, which are adverse effects of dobutamine. Therefore, this choice is incorrect.
Choice D Reason: Dobutamine also has a positive chronotropic effect, which means it increases the heart rate. However, this is not a desired outcome for a client with heart failure, as it increases the oxygen demand of the heart and may worsen the condition. Therefore, this choice is incorrect.

Correct Answer is B
Explanation
Choice A Reason: Observing for cerebrospinal fluid (CSF) leaks from the evacuation site is important, but not the first action that the nurse should take. CSF leaks can indicate a breach in the dura mater, which can increase the risk of infection and meningitis. The nurse should inspect the dressing and the nose and ears for any clear or bloody drainage, and report any findings to the provider. However, these measures are secondary to ensuring adequate oxygenation and perfusion.
Choice B Reason: The first action the nurse should take when caring for a client post-evacuation of a subdural hematoma is to check the oximeter to ensure adequate oxygenation. Maintaining proper oxygenation is a priority because hypoxia and hypercapnia can lead to cerebral vasodilation, increasing intracranial pressure (ICP) and worsening neurological outcomes.Key Concept: Always prioritize Airway, Breathing, and Circulation (ABCs) when determining the most immediate nursing intervention.
Choice C Reason: Assessing for an increase in temperature is another important action, but not the first one that the nurse should take. An increase in temperature can indicate an infection, inflammation, or damage to the hypothalamus, which can affect the thermoregulation of the body. The nurse should monitor the temperature and administer antipyretics as prescribed. However, these measures are secondary to ensuring adequate oxygenation and perfusion.
Choice D Reason:This is crucial, but oxygenation status should be checked first since low oxygen levels can worsen ICP.
Correct Answer is B
Explanation
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.
