Question

A nurse is caring for a client who has sustained a traumatic brain injury. The nurse should monitor the client for which of the following manifestations of increased intracranial pressure?

Answer 1

Correct Answers:

Decreased level of consciousness

Rationale :

🎀 Decreased level of consciousness is the earliest and most sensitive indicator of increased intracranial pressure (ICP).

🎀 Rising ICP reduces cerebral perfusion, leading to altered mental status, confusion, or lethargy.

🎀 Subtle changes such as restlessness, slowed responses, or difficulty arousing often appear before vital-sign changes.

🎀 Ongoing ICP elevation causes brain tissue compression, directly impairing cortical function.

🎀 Continuous neurologic assessment is critical because LOC changes precede irreversible brain injury.

Tachypnea

🎀 ICP changes typically cause irregular or slowed respirations, not tachypnea.

🎀 Rapid breathing is more commonly related to pain, anxiety, or metabolic issues.

Bilateral weakness of extremities

🎀 Motor weakness can occur, but it is not the earliest sign of increased ICP.

🎀 It usually reflects advanced neurologic compromise.

Hypotension

🎀 Increased ICP is associated with hypertension, not hypotension, as part of Cushing’s triad.

🎀 Hypotension actually worsens cerebral perfusion, but it is not caused by ICP elevation.

Answer 2

Correct Answers:

Administer ammonium chloride.

Rationale :

🎀 Phencyclidine (PCP) is a weak base, and its elimination is enhanced when the urine is acidified.

🎀 Ammonium chloride acidifies the urine, which increases renal excretion of PCP and helps reduce toxicity levels.

🎀 This intervention directly targets the pharmacokinetics of PCP, making it a specific and effective nursing action.

🎀 Faster elimination helps decrease the duration of neuropsychiatric effects, such as agitation, hallucinations, and psychosis.

🎀 Supporting drug clearance is a priority in overdose management once airway, breathing, and circulation are stable.

Reverse the toxicity with naloxone

🎀 Naloxone reverses opioid toxicity, not PCP intoxication.

🎀 PCP does not act on opioid receptors, so naloxone would be ineffective.

Verbally attempt to calm the client

🎀 Clients with PCP intoxication often exhibit severe agitation and psychosis, making verbal calming ineffective.

🎀 Excess stimulation can actually worsen agitation and violent behavior.

Administer warmed IV fluids to counteract hypothermia

🎀 PCP toxicity more commonly causes hyperthermia, not hypothermia.

🎀 Warming measures could worsen temperature-related complications.

Answer 3

Correct Answers:

Reduce edema of the brain.

Rationale :

🎀 Osmotic diuretics (such as mannitol) work by pulling fluid from swollen brain tissue into the bloodstream, which directly reduces cerebral edema.

🎀 By decreasing brain swelling, the medication helps lower intracranial pressure (ICP) and improves cerebral perfusion.

🎀 Reducing edema prevents compression of brain structures, which lowers the risk of herniation.

🎀 The shift of fluid from the brain into the vascular space allows excess fluid to be excreted by the kidneys.

🎀 This mechanism is a key emergency intervention in clients with elevated ICP.

Increase cell size in the brain

🎀 Osmotic diuretics do the opposite, pulling water out of brain cells, not into them.

🎀 Increasing cell size would worsen cerebral edema and ICP, making this incorrect.

Expand extracellular fluid volume

🎀 Although fluid initially shifts into the bloodstream, this is not the therapeutic goal.

🎀 The primary purpose is brain decompression, not volume expansion.

Provide fluid hydration

🎀 Osmotic diuretics actually promote diuresis, which can lead to fluid loss.

🎀 They are not used for hydration, but for ICP reduction.

Answer 4

Correct Answers:

"Do not drink alcohol while taking this medication."

Rationale :

🎀 Disulfiram works by blocking the metabolism of alcohol, causing a rapid buildup of acetaldehyde in the body.

🎀 Consuming alcohol while on disulfiram can trigger a severe and potentially life-threatening reaction, including flushing, nausea, vomiting, headache, chest pain, hypotension, and tachycardia.

🎀 Even small amounts of alcohol, including those found in mouthwash, cough syrups, sauces, or hand sanitizers, can provoke this reaction.

🎀 The medication is used as a deterrent therapy to support abstinence from alcohol in clients with alcohol use disorder.

🎀 Strict avoidance of alcohol is essential for client safety and treatment effectiveness.

Avoid grapefruit juice while taking this medication

🎀 Grapefruit juice affects CYP450 enzymes, but this interaction is not clinically significant with disulfiram.

🎀 Alcohol avoidance, not grapefruit restriction, is the primary teaching point.

Do not crush this medication before swallowing

🎀 Disulfiram tablets may be crushed if needed, especially for clients with swallowing difficulty.

🎀 Crushing does not alter its safety or effectiveness.

Take this medication with food

🎀 Disulfiram can be taken with or without food.

🎀 Food intake is not the key safety concern with this medication.

Answer 5

Correct Answers:

Genetics

Rationale :

🎀 Genetics is a nonmodifiable risk factor because inherited traits and family history cannot be changed and significantly influence an individual’s risk of developing a stroke.

🎀 A family history of stroke increases susceptibility due to genetic predisposition affecting blood vessels, clotting mechanisms, and lipid metabolism.

🎀 Clients with genetic risk require early screening and aggressive management of modifiable risk factors to reduce overall stroke risk.

🎀 Understanding genetic risk helps guide preventive education and long-term monitoring.

🎀 This factor remains present regardless of lifestyle changes or medical interventions.

History of smoking

🎀 Smoking is a modifiable risk factor because cessation can significantly reduce stroke risk.

🎀 Lifestyle changes and counseling can effectively address this risk.

Obesity

🎀 Obesity is modifiable through diet, exercise, and behavioral changes.

🎀 Weight reduction lowers associated risks such as hypertension and diabetes.

History of hypertension

🎀 Hypertension can be managed with medications and lifestyle modifications.

🎀 Blood pressure control greatly reduces stroke incidence.

Answer 6

Correct Answers:

Acute compartment syndrome

Rationale :

🎀 Acute compartment syndrome occurs when increased pressure within a closed muscle compartment compromises circulation and tissue perfusion.

🎀 Increasing calf edema after multiple leg fractures is a classic early manifestation because swelling and bleeding raise intra compartmental pressure.

🎀 As pressure rises, venous outflow is obstructed first, leading to progressive swelling and worsening edema.

🎀 Untreated pressure can result in ischemia, nerve damage, muscle necrosis, and permanent loss of function.

🎀 Early recognition of increasing edema is critical to allow urgent intervention such as fasciotomy.

Pulmonary embolism

🎀 Pulmonary embolism primarily presents with sudden dyspnea, chest pain, tachypnea, and hypoxia, not localized calf edema.

🎀 While DVT can cause calf swelling, the question emphasizes post-fracture limb pressure, pointing away from PE.

Fat embolism syndrome

🎀 Fat embolism syndrome is associated with long-bone fractures and manifests with respiratory distress, petechiae, and neurologic changes.

🎀 Localized increasing calf edema is not a hallmark feature.

Malignant hypothermia

🎀 Malignant hypothermia is a genetic reaction to anesthetic agents, characterized by hyperthermia, muscle rigidity, and acidosis.

🎀 It does not cause localized limb edema.

Answer 7

Correct Answers:

The client's bladder becomes distended.

Rationale :

🎀 Autonomic dysreflexia is a life-threatening complication seen in clients with spinal cord injuries at or above T-6, making this client with a T-4 injury highly susceptible.

🎀 Bladder distention is the most common triggering stimulus, causing a noxious signal below the level of injury that the body cannot regulate appropriately.

🎀 The distended bladder leads to uncontrolled sympathetic stimulation, resulting in severe vasoconstriction and sudden hypertension.

🎀 Identifying bladder distention early allows the nurse to intervene promptly and prevent progression to a full autonomic dysreflexia episode.

🎀 Preventing bladder overfilling is a key priority in nursing care for clients at risk.

The client states having a severe headache

🎀 A severe headache is a manifestation of autonomic dysreflexia, not a risk indicator.

🎀 It usually appears after the condition has already begun.

The client's blood pressure becomes elevated

🎀 Hypertension is a hallmark sign during an episode, not an early risk factor.

🎀 Blood pressure elevation reflects active autonomic dysreflexia, not risk.

The client states having nasal congestion

🎀 Nasal congestion occurs due to parasympathetic overactivity above the injury level.

🎀 It is a symptom of the condition, not a precipitating cause.

Answer 8

Correct Answers:

"You should avoid or cut down on alcohol and caffeine which can aggravate GERD."

Rationale :

🎀 Alcohol relaxes the lower esophageal sphincter (LES), allowing gastric contents to reflux into the esophagus more easily.

🎀 Caffeine also decreases LES tone and stimulates gastric acid secretion, both of which worsen reflux symptoms.

🎀 Reducing alcohol and caffeine intake helps minimize esophageal irritation and decreases the frequency of heartburn and regurgitation.

🎀 Lifestyle modification, including limiting these substances, is a first-line management strategy for GERD.

🎀 Avoidance supports symptom control and reduces the risk of chronic esophageal inflammation.

You should avoid possible mercury-containing foods such as some seafood because of their risk to GERD.

🎀 Mercury exposure is unrelated to GERD pathophysiology.

🎀 Seafood does not directly affect LES function or acid reflux.

It is okay to take aspirin with GERD.

🎀 Aspirin can irritate the gastric and esophageal mucosa.

🎀 It may worsen reflux symptoms and increase ulcer risk.

There is no causal link between lying down after eating and increased onset of GERD.

🎀 Lying flat after meals promotes reflux by reducing the effect of gravity.

🎀 This action increases acid exposure to the esophagus.

Answer 9

Correct Answers:

bleeding.

Rationale :

🎀 Idiopathic (autoimmune) thrombocytopenic purpura (ITP) is characterized by immune-mediated destruction of platelets, leading to thrombocytopenia.

🎀 A low platelet count significantly increases the risk for spontaneous bleeding, including petechiae, ecchymosis, epistaxis, gingival bleeding, hematuria, and gastrointestinal or intracranial hemorrhage.

🎀 Bleeding is the most immediate and life-threatening complication, making it the highest nursing priority.

🎀 Early detection of bleeding allows for rapid intervention, such as platelet transfusion, corticosteroids, or IV immunoglobulin.

🎀 Nursing care focuses on preventing trauma, monitoring skin and mucous membranes, and assessing for occult bleeding.

Fatigue

🎀 Fatigue may occur secondary to illness or anemia but is not immediately life-threatening.

🎀 It does not pose the same acute risk as uncontrolled bleeding.

Side effects of immunosuppressants

🎀 Monitoring for medication side effects is important but is a secondary concern.

🎀 These effects typically develop over time, not acutely.

Constipation

🎀 Constipation is not directly related to platelet destruction or bleeding risk.

🎀 It does not represent a priority safety concern in ITP.

Answer 10

Correct Answers:

The client consumed alcohol while taking the medication.

Rationale :

🎀 Disulfiram works by inhibiting alcohol metabolism, causing acetaldehyde accumulation when alcohol is consumed.

🎀 When alcohol is taken with disulfiram, it triggers a disulfiram–alcohol reaction, which commonly causes severe nausea and vomiting.

🎀 This reaction can also include flushing, headache, palpitations, hypotension, and shortness of breath, making it very distressing.

🎀 Even small amounts of alcohol, including those in mouthwash, cough syrups, sauces, or hand sanitizers, can provoke symptoms.

🎀 Experiencing these intense symptoms often leads clients to stop the medication abruptly, as described in this scenario.

The client experienced a common side effect to the medication

🎀 Mild side effects of disulfiram may include drowsiness or metallic taste, not severe vomiting.

🎀 The intensity described suggests a reaction, not a routine side effect.

The client took an overdose of the medication

🎀 Disulfiram overdose is rare and would cause neurologic or cardiovascular symptoms beyond nausea alone.

🎀 The scenario does not indicate excess dosing.

The client demonstrated an allergic response to the medication

🎀 Allergic reactions typically present with rash, pruritus, or swelling, not isolated nausea and vomiting.

🎀 There is no indication of hypersensitivity symptoms.
