The client is a 43-year-old male who had a surgical removal of a benign tumor from the left hemisphere of his brain. The client's estimated blood loss (EBL) is 100 mL during surgical procedure. There were no complications. Vital signs remained stable throughout the procedure. The client will be admitted to the neurological intensive care unit for monitoring.

Answer and Explanation

The Correct Answer is []

Place the call light within the client's reach. The client has undergone surgery on the left hemisphere of the brain, which controls speech and motor function on the right side. This may lead to temporary weakness or speech difficulties, making it essential to ensure easy access to the call light for assistance.
Use a word board to help the client communicate. Damage to the left hemisphere can result in Broca aphasia, where the client has difficulty producing speech but can still understand language. A word board or communication aid allows the client to express needs effectively despite speech limitations.
Cerebral perfusion pressure. Monitoring cerebral perfusion pressure (CPP) is essential after brain surgery to ensure the brain is receiving adequate blood flow. Low CPP can lead to ischemia, while high CPP may indicate increased intracranial pressure (ICP), both of which can result in serious complications.
Level of consciousness. Assessing neurological status frequently helps detect early signs of deterioration, such as worsening intracranial pressure, cerebral edema, or postoperative bleeding. Changes in alertness, responsiveness, or confusion may indicate a need for urgent intervention.
Broca aphasia. Since the left hemisphere controls speech production, surgery in this area may cause Broca aphasia, where the client understands language but struggles to form words or complete sentences. The use of alternative communication methods is necessary to assist the client in expressing their needs.
Prepare the client to return to surgery. There is no indication of complications requiring an immediate return to the operating room. The estimated blood loss (100 mL) is minimal, and vital signs remained stable throughout the procedure.
Give ibuprofen as ordered. Ibuprofen (a nonsteroidal anti-inflammatory drug - NSAID) is contraindicated postoperatively because it can increase the risk of bleeding by inhibiting platelet function. Acetaminophen is typically preferred for pain control.
Elevate the head of the bed to 45 degrees. After brain surgery, the head of the bed should be elevated to 30 degrees, not 45 degrees. This optimizes cerebral venous drainage while preventing excessive intracranial pressure (ICP) changes that could impair perfusion.
White blood cell count. WBC count may be monitored for infection, but immediate concerns after brain surgery focus on neurological status and cerebral perfusion rather than infection unless symptoms of fever or worsening condition develop.
Pupil response. While pupil assessment is a key neurological parameter, it is more relevant for clients at risk of brain herniation or severe ICP elevation. In this case, monitoring level of consciousness and cerebral perfusion pressure takes priority.
Deep tendon reflexes. Reflex testing is not a primary concern after brain surgery unless there are signs of spinal cord involvement or a progressive neurological disorder. Monitoring motor function and speech ability is more relevant.
Myasthenia gravis. Myasthenia gravis is an autoimmune neuromuscular disorder that causes muscle weakness but is unrelated to brain tumor removal.
Cushing response. Cushing's response is a late sign of increased intracranial pressure (ICP), characterized by hypertension, bradycardia, and irregular respirations. The client has no signs of worsening ICP at this time.
Hydrocephalus. Hydrocephalus is excess cerebrospinal fluid (CSF) accumulation, which typically requires a shunt or external ventricular drain (EVD). There is no indication of CSF buildup in this client.

Correct Answer is ["B","C","D"]

Explanation

A. Promote oxygenation to tissues. Oxygenation is not a primary goal in DKA management unless there is a coexisting condition causing hypoxia. DKA primarily leads to metabolic acidosis and dehydration rather than respiratory failure, and oxygenation is typically maintained unless complications such as pneumonia or severe shock develop.
B. Reverse dehydration. Severe dehydration occurs in DKA due to osmotic diuresis caused by hyperglycemia. The priority is to restore intravascular volume with isotonic IV fluids such as 0.9% normal saline to improve circulation, support kidney function, and prevent shock. Fluid replacement is essential for stabilizing blood pressure and promoting glucose clearance.
C. Replace insulin. The lack of insulin is the primary cause of DKA, leading to unchecked lipolysis and ketone production. IV insulin therapy is necessary to suppress ketogenesis, lower blood glucose levels, and allow cells to use glucose for energy. Insulin must be administered cautiously with continuous monitoring to prevent hypoglycemia and electrolyte imbalances.
D. Correct electrolytes that are out of normal range. Electrolyte imbalances, particularly potassium depletion, are common in DKA due to osmotic losses and shifting caused by insulin therapy. Potassium replacement is required even if levels appear normal initially, as insulin will drive potassium into cells, leading to hypokalemia. Sodium and bicarbonate levels should also be monitored and corrected as needed.
E. Provide respiratory support. Respiratory support is not typically required unless the client experiences severe respiratory distress or altered mental status. Kussmaul respirations are a natural compensatory mechanism that helps the body exhale CO₂ and correct acidosis. Supplemental oxygen is only necessary if there is an underlying pulmonary condition or respiratory failure.
F. Prevent hyperventilation. Hyperventilation in the form of Kussmaul respirations is the body's way of compensating for metabolic acidosis. It should not be suppressed, as it plays a crucial role in reducing acid buildup. Treating the underlying cause of DKA with fluids, insulin, and electrolyte replacement will allow respiratory function to normalize.

A. Temperature. B. Heart sounds. C. Urinary output. D. Pupil response.

Correct Answer is C

Explanation

A. Temperature. While temperature monitoring is important in septic shock to assess infection control, it is not an indicator of dopamine's effectiveness. Dopamine primarily affects renal perfusion and blood pressure, not body temperature regulation.
B. Heart sounds. Dopamine is a vasopressor and inotropic agent, but it does not directly impact heart sounds. While it can increase myocardial contractility, assessing blood pressure and perfusion parameters is more relevant in evaluating its therapeutic effects.
C. Urinary output. Low-dose dopamine (1-5 mcg/kg/min) primarily acts as a dopaminergic agonist, increasing renal blood flow and urine output by dilating renal arteries. In septic shock, maintaining adequate kidney perfusion is critical to prevent acute kidney injury (AKI). A therapeutic response to dopamine would be seen as improved urinary output (≥ 30 mL/hr), indicating effective renal perfusion.
D. Pupil response. Dopamine does not directly affect pupil size or reactivity. Pupil assessment is more relevant in neurological evaluations, not in monitoring the effects of dopamine in septic shock.
