A nurse is caring for a client who has a traumatic brain injury. The nurse notes that the client has a widening pulse pressure. Which of the following actions should the nurse take?
A. Administer a vasodilator medication.
Reason: This choice is incorrect because administering a vasodilator medication may lower the blood pressure and worsen the cerebral perfusion. A vasodilator medication is a drug that relaxes the blood vessels and reduces the resistance to blood flow. It may be used for clients who have hypertension, angina, or heart failure, but it does not help to reduce the intracranial pressure (ICP).
B. Elevate the head of the bed to 30°.
Reason: This choice is correct because elevating the head of the bed to 30° may help to improve the venous drainage and decrease the ICP. ICP is the pressure exerted by the brain tissue, cerebrospinal fluid (CSF), and blood within the cranial cavity. A normal ICP range is 5 to 15 mm Hg, and an elevated ICP (>20 mm Hg) can cause cerebral ischemia, herniation, or death. Therefore, positioning the client in a semi-Fowler's position (30° angle) or high- Fowler's position (60° to 90° angle) can facilitate breathing and prevent further complications.
C. Apply a cold compress to the forehead.
Reason: This choice is incorrect because applying a cold compress to the forehead may cause vasoconstriction and increase the ICP. A cold compress is a device that applies cold temperature to a body part to reduce inflammation, pain, or swelling. It may be used for clients who have headaches, sprains, or bruises, but it does not help to reduce the ICP.
D. Decrease the oxygen flow rate.
Reason: This choice is incorrect because decreasing the oxygen flow rate may cause hypoxia and worsen the cerebral ischemia. Hypoxia is a condition in which the body or a part of it does not receive enough oxygen. It may cause symptoms such as confusion, agitation, or cyanosis. Therefore, providing adequate oxygenation and ventilation is essential to maintain the brain function and prevent further damage.

A nurse is assessing a client in the oliguric phase of acute kidney injury. Which of the following findings should the nurse expect?
A. Hypomagnesemia
Reason: This choice is incorrect because hypomagnesemia is not a common finding in the oliguric phase of acute kidney injury. Hypomagnesemia is a condition in which the serum magnesium level is lower than normal (less than 1.5 mEq/L). It may be caused by various factors such as malnutrition, diarrhea, diuretics, or alcohol abuse. It may cause symptoms such as muscle weakness, tremors, tetany, or cardiac arrhythmias.
B. Hyperkalemia
Reason: This choice is correct because hyperkalemia is a common finding in the oliguric phase of acute kidney injury. Hyperkalemia is a condition in which the serum potassium level is higher than normal (more than 5 mEq/L). It may be caused by reduced renal excretion of potassium due to decreased urine output (oliguria). It may cause symptoms such as muscle weakness, paresthesia, bradycardia, or cardiac arrest.
C. Decreased creatinine level
Reason: This choice is incorrect because decreased creatinine level is not a common finding in the oliguric phase of acute kidney injury. Creatinine is a waste product of muscle metabolism that is filtered by the kidneys and excreted in urine. A normal creatinine level ranges from 0.6 to 1.2 mg/dL for men and 0.5 to 1.1 mg/dL for women. In acute kidney injury, creatinine level usually increases due to reduced renal function and impaired clearance of creatinine.
D. Increased glomerular filtration rate (GFR)
Reason: This choice is incorrect because increased glomerular filtration rate (GFR) is not a common finding in the oliguric phase of acute kidney injury. GFR is a measure of how well the kidneys filter blood and remove waste products. A normal GFR range is 90,to 120 mL/min/1.73 m2. In acute kidney injury, GFR usually decreases due to reduced blood flow,to,the kidneys or damage to the glomeruli, which are the tiny blood vessels that filter blood in the kidneys.

A nurse is caring for a client who has increased intracranial pressure. Which of the following interventions should the nurse take?
A. Provide a brightly lit environment.
Reason: This choice is incorrect because providing a brightly lit environment may stimulate the client and increase the intracranial pressure. A brightly lit environment is an environment that has a high level of illumination or brightness. It may be used for clients who have depression, seasonal affective disorder, or insomnia, but it does not help to reduce the intracranial pressure.
B. Teach controlled coughing and deep breathing.
Reason: This choice is incorrect because teaching controlled coughing and deep breathing may increase the intrathoracic pressure and increase the intracranial pressure. Controlled coughing and deep breathing are techniques that help to clear the airway and improve lung expansion. They may be used for clients who have respiratory infections, chronic obstructive pulmonary disease, or postoperative complications, but they do not help to reduce the intracranial pressure.
C. Encourage a minimum intake of 2000 mL (67.5 oz) of clear fluids per day.
Reason: This choice is incorrect because encouraging a minimum intake of 2000 mL (67.5 oz) of clear fluids per day may cause fluid overload and increase the intracranial pressure. Fluid overload is a condition in which the body has too much fluid, which can impair the function of the heart, lungs, and kidneys. Therefore, restricting fluid intake and using diuretics may be indicated for clients who have increased intracranial pressure.
D. Elevate the head of the bed 20°.
Reason: This choice is correct because elevating the head of the bed 20° may help to improve the venous drainage and decrease the intracranial pressure. As explained above, positioning the client in a semi-Fowler's or high-Fowler's position can facilitate breathing and prevent further complications. However, elevating the head of the bed more than 30° may decrease the cerebral perfusion pressure (CPP), which is the difference between the mean arterial pressure (MAP) and the intracranial pressure (ICP). A normal CPP range is 70 to 100 mm Hg, and a low CPP (<50 mm Hg) can cause cerebral ischemia, herniation, or death. Therefore, elevating the head of the bed to a moderate angle (20°) may be optimal for clients who have increased ICP.

A client who is having burn debridement states, "You are the worst nurse I have ever seen. All you do is hurt me." Which of the following responses should the nurse make?
A. "That's a hurtful thing to say."
Reason: This choice is incorrect because it reflects the nurse's feelings rather than focusing on the client's needs. Saying "That's a hurtful thing to say" may make the client feel guilty or defensive, and it does not address the underlying cause of the client's anger or frustration.
B. "Why would you say such a thing?"
Reason: This choice is incorrect because it sounds accusatory and confrontational rather than empathetic and supportive. Asking "Why would you say such a thing?" may make the client feel judged or criticized, and it does not explore the client's feelings or concerns.
C. "Well, that's your opinion."
Reason: This choice is incorrect because it dismisses the client's feelings rather than acknowledging them. Saying "Well, that's your opinion" may make the client feel ignored or invalidated, and it does not show respect or compassion for the client.
D. "Tell me more about that."
Reason: This choice is correct because it invites the client to express their feelings and concerns rather than shutting them down. Saying "Tell me more about that" may make the client feel heard and understood, and it may help to identify the source of their anger or frustration. The nurse can then use therapeutic communication skills such as active listening, reflecting, clarifying, or validating to establish rapport and trust with the client.
