Question

A patient diagnosed with cerebral aneurysm reports 'the worst headache ever' to the nurse. What action is the priority?

Answer 1

Correct Answers:

Call the physician immediately

Rationale :

✔ A sudden, severe headache described as the "worst headache ever" is a classic sign of a ruptured cerebral aneurysm or subarachnoid hemorrhage (SAH). This is a medical emergency requiring immediate intervention.

✔ Promptly notifying the physician ensures rapid evaluation and treatment to prevent further intracranial bleeding, increased intracranial pressure (ICP), and neurological deterioration.

✔ Delayed treatment can lead to complications such as brain damage, vasospasm, seizures, coma, or death. Early recognition significantly improves patient outcomes.

✔ The nurse's priority is to recognize the life-threatening change in condition and activate the appropriate medical response rather than managing the symptom independently.

✔ After notifying the physician, the nurse should continue monitoring the patient's neurological status, vital signs, and level of consciousness while preparing for emergency treatment.

❌ Sit with the patient for a few minutes.

✘ Providing reassurance is important, but it does not address the underlying medical emergency.

✘ Delaying definitive treatment may result in rapid neurological deterioration.

❌ Administer an analgesic.

✘ An analgesic may temporarily relieve pain but does not treat a ruptured cerebral aneurysm.

✘ The priority is rapid medical evaluation before symptom management.

❌ Inform the nurse manager.

✘ The nurse manager is not responsible for the immediate treatment of an acute neurological emergency.

✘ The priority is to notify the physician so emergency interventions can begin without delay.

Answer 2

Correct Answers:

Maintain cardiac output by controlling ventricular heart rate

Rationale :

❤️ Atrial fibrillation (AF) causes rapid, irregular electrical activity in the atria, resulting in an irregular ventricular rhythm.

❤️ A ventricular rate of 166 BPM significantly reduces ventricular filling time, leading to decreased cardiac output.

❤️ The immediate treatment goal is to control the ventricular rate so the ventricles have enough time to fill and pump blood effectively.

❤️ Restoring adequate cardiac output improves tissue perfusion and reduces symptoms such as hypotension, dizziness, and chest discomfort.

❤️ Medications such as beta-blockers or calcium channel blockers are commonly used to slow the ventricular response.

❌ Maintain anticoagulation.

✘ Anticoagulation helps prevent thromboembolic complications, but it does not correct the immediate problem of a rapid ventricular response.

✘ Preventing stroke is important, but stabilizing hemodynamic status is the priority.

❌ Decrease SA node conduction.

✘ Atrial fibrillation originates in the atria, not the SA node.

✘ Treatment focuses on slowing conduction through the AV node to reduce the ventricular rate.

❌ Improve oxygenation.

✘ Supplemental oxygen may be necessary if hypoxemia is present, but it does not treat the underlying tachyarrhythmia.

✘ Controlling the ventricular rate is the primary treatment goal.

Answer 3

Correct Answers:

Normalize BP within 24–48 hours

Rationale :

🚨 Hypertensive urgency is characterized by severely elevated blood pressure without evidence of acute target-organ damage.

🚨 Blood pressure should be lowered gradually over 24–48 hours to reduce the risk of complications.

🚨 Rapid blood pressure reduction may decrease cerebral, renal, and coronary perfusion, leading to ischemia.

🚨 Oral antihypertensive medications are typically sufficient because there is no immediate organ damage.

🚨 Close monitoring ensures safe blood pressure reduction while preventing adverse effects.

❌ Normalize BP within 2 hours.

✘ Rapid blood pressure reduction is indicated in a hypertensive emergency, not a hypertensive urgency.

✘ Lowering BP too quickly may cause organ hypoperfusion.

❌ BP <110/70 mm Hg within 36 hours.

✘ The goal is gradual reduction, not achieving a specific low blood pressure target immediately.

✘ Excessive reduction increases the risk of cerebral and renal ischemia.

❌ BP <120/80 mm Hg within 36 hours.

✘ Normal blood pressure is not the immediate treatment goal during hypertensive urgency.

✘ Therapy should focus on safe, controlled blood pressure reduction.

Answer 4

Correct Answers:

Potassium level

Rationale :

💊 Hypokalemia increases the risk of digoxin toxicity by enhancing digoxin binding to the Na⁺/K⁺-ATPase pump.

💊 Patients with low potassium levels are more susceptible to toxic effects even when digoxin levels are therapeutic.

💊 Digoxin toxicity may present with nausea, vomiting, visual disturbances, and cardiac dysrhythmias.

💊 Assessing the potassium level helps identify and correct a major contributing factor.

💊 Correcting electrolyte imbalances is an essential component of managing digoxin toxicity.

❌ Peripheral pulses.

✘ Assessing peripheral pulses provides cardiovascular information but does not identify the cause of digoxin toxicity.

✘ The potassium level is a more critical assessment.

❌ Skin turgor.

✘ Skin turgor evaluates hydration status, not digoxin toxicity.

✘ It does not help identify the underlying cause of the patient's symptoms.

❌ White blood cell count.

✘ A WBC count is useful when assessing for infection.

✘ It is not associated with the development or diagnosis of digoxin toxicity.

Answer 5

Correct Answers:

62.5 gtt/min

Rationale :

💧 The formula

Drip rate = (Volume × Drop factor) ÷ Time in minutes

💧 Identify the values

Volume = 250 mL
Drop factor = 15 gtt/mL
Time = 1 hour = 60 minutes

💧 Substitute the values

Drip rate = (250 mL × 15 gtt/mL) ÷ 60 minutes

💧 Multiply

250 × 15 = 3,750 gtt

💧 Divide

3,750 ÷ 60

👉= 62.5 gtt/min

❌ 250 mL/hr.

✘ This is the pump rate in mL/hr, not the manual gravity drip rate.

✘ The question asks for gtt/min, so conversion using the drop factor is required.

❌ 44 gtt/min.

✘ This value results from an incorrect calculation.

✘ Always apply the formula using the prescribed drop factor and infusion time.

❌ 1000 gtt/min.

✘ This drip rate is excessively high and would infuse the medication within minutes.

✘ Always verify calculations to avoid potentially dangerous infusion errors.

Answer 6

Correct Answers:

Thrombus formation
Anticoagulant therapy

Rationale :

🩸 Thrombus formation occurs because the atria do not contract effectively during atrial fibrillation. Instead, they quiver rapidly, causing blood stasis, especially in the left atrial appendage, which promotes clot formation.

🩸 When blood remains stagnant, it is more likely to clot due to activation of the body's normal coagulation cascade. These clots can enlarge over time if the abnormal rhythm persists.

🩸 If a thrombus breaks loose, it becomes an embolus that can travel through the arterial circulation. An embolus that reaches the brain may block cerebral blood flow and cause an ischemic stroke, one of the most serious complications of atrial fibrillation.

🩸 Anticoagulant therapy is prescribed to reduce the blood's ability to form harmful clots. Although these medications do not dissolve existing clots or restore a normal heart rhythm, they significantly reduce the risk of new clot formation.

🩸 Common anticoagulants include warfarin, apixaban, rivaroxaban, dabigatran, and edoxaban. The choice of medication depends on the patient's risk factors, kidney function, and overall clinical condition.

🩸 Patients receiving anticoagulant therapy should be monitored for signs of bleeding, such as hematuria, melena, easy bruising, or prolonged bleeding from minor cuts. They should also be educated about medication adherence and avoiding activities that increase bleeding risk.

Answer 7

Correct Answers:

Elevate lower extremities

Rationale :

🌿 Peripheral venous disease occurs when the venous valves become damaged or incompetent.

🌿 Damaged valves allow blood to pool in the lower extremities, leading to increased venous pressure and edema.

🌿 Elevating the lower extremities above the level of the heart uses gravity to improve venous return.

🌿 Improved venous return reduces venous congestion, decreases swelling, and relieves discomfort.

🌿 Reducing edema improves the delivery of oxygen and nutrients to the affected tissues.

🌿 Better tissue perfusion promotes wound healing and helps prevent further skin breakdown.

🌿 Leg elevation is a standard treatment for venous ulcers and is commonly combined with compression therapy for optimal healing.

🌿 Patients should also avoid prolonged standing or sitting, as both increase venous stasis and delay healing.

❌ Dangle legs over bed.

✘ Dangling the legs increases venous pooling because gravity causes more blood to collect in the lower extremities.

✘ Increased venous pressure worsens edema and slows the healing of venous ulcers.

✘ This position is recommended for some patients with peripheral arterial disease, not peripheral venous disease.

❌ Keep legs flat and straight.

✘ Keeping the legs flat does not significantly improve venous return.

✘ Venous congestion and swelling may continue because gravity is not assisting blood flow back to the heart.

✘ Elevating the legs provides much greater therapeutic benefit than keeping them flat.

❌ Knees bent at 45° with pillows.

✘ Excessive knee flexion may partially compress the popliteal veins.

✘ Compression of the veins can further impair venous circulation.

✘ The legs should be elevated with minimal knee flexion to promote optimal venous return.

Answer 8

Correct Answers:

Friction rub

Rationale :

🎧 Pericarditis is an inflammation of the pericardium, the protective sac surrounding the heart.

🎧 As the inflamed pericardial layers rub against each other during the cardiac cycle, they produce a characteristic pericardial friction rub.

🎧 A friction rub is a high-pitched, scratchy, or grating sound that is best heard with the diaphragm of the stethoscope.

🎧 The sound is most clearly auscultated at the left lower sternal border while the patient is sitting upright and leaning forward.

🎧 Unlike normal heart sounds, a friction rub may have up to three components, corresponding to atrial systole, ventricular systole, and early ventricular diastole.

🎧 Identifying a pericardial friction rub is an important clinical finding because it strongly suggests acute pericarditis and warrants further evaluation and treatment.

❌ Coarse crackles.

✘ Coarse crackles are abnormal lung sounds caused by fluid or secretions in the larger airways.

✘ They are commonly associated with conditions such as pulmonary edema, pneumonia, or bronchitis, not pericarditis.

✘ These sounds are heard during respiration, whereas a friction rub is a cardiac sound.

❌ Wheezes.

✘ Wheezes are continuous, high-pitched respiratory sounds produced by narrowed or obstructed airways.

✘ They are most commonly heard in asthma, COPD, or bronchospasm.

✘ Pericarditis affects the pericardium, not the airways, so wheezing is not an expected finding.

❌ Fine crackles.

✘ Fine crackles are soft, high-pitched lung sounds heard when collapsed alveoli reopen during inspiration.

✘ They are commonly associated with heart failure, pulmonary fibrosis, or interstitial lung disease.

✘ Although heart failure may produce fine crackles, the hallmark auscultatory finding in pericarditis is a pericardial friction rub.

Answer 9

Correct Answers:

Bleeding

Rationale :

🩸 Tissue plasminogen activator (tPA) is a thrombolytic medication that works by dissolving the blood clot responsible for an ischemic stroke.

🩸 Because tPA breaks down blood clots, it significantly increases the patient's risk of bleeding during and after treatment.

🩸 The most serious complication of tPA therapy is intracranial hemorrhage, which can rapidly worsen the patient's neurological condition.

🩸 The nurse should closely monitor for signs of bleeding, including severe headache, decreased level of consciousness, hematuria, melena, bleeding gums, or excessive bleeding from IV sites.

🩸 Frequent neurological assessments and vital sign monitoring are essential after administering tPA because early detection of bleeding improves patient outcomes.

🩸 Invasive procedures such as intramuscular injections, unnecessary venipunctures, or insertion of invasive devices should be avoided whenever possible to minimize the risk of bleeding.

❌ Acute pain.

✘ Acute pain may occur in many medical conditions but is not the primary complication associated with tPA therapy.

✘ Although a sudden severe headache should never be ignored, it is concerning because it may indicate intracranial bleeding, not simply pain.

✘ The nurse's priority is to determine whether the pain is a symptom of a hemorrhagic complication.

❌ Septicemia.

✘ Septicemia is a bloodstream infection caused by microorganisms entering the circulation.

✘ It is not a direct adverse effect of tPA administration and is unrelated to the medication's mechanism of action.

✘ While infection prevention remains important, monitoring for bleeding is the immediate priority after thrombolytic therapy.

❌ Seizures.

✘ Seizures may occur after a stroke, particularly when there is significant brain injury, but they are not the most common complication of tPA.

✘ A patient who develops seizures after receiving tPA should also be evaluated for possible intracranial hemorrhage.

✘ The nurse should prioritize surveillance for bleeding, as it is the most serious medication-related complication.

Answer 10

Correct Answers:

Evidence of target organ damage

Rationale :

🚨 A hypertensive emergency is characterized by a severely elevated blood pressure accompanied by acute target organ damage.

🚨 Target organs commonly affected include the brain, heart, kidneys, eyes, and major blood vessels.

🚨 Examples of target organ damage include stroke, myocardial infarction, acute heart failure, pulmonary edema, acute kidney injury, hypertensive encephalopathy, and aortic dissection.

🚨 The presence of target organ damage, rather than the actual blood pressure reading, distinguishes a hypertensive emergency from a hypertensive urgency.

🚨 A hypertensive emergency requires immediate treatment with intravenous antihypertensive medications in a closely monitored setting to prevent further organ injury.

🚨 In contrast, a hypertensive urgency involves severely elevated blood pressure without evidence of acute target organ damage and is usually managed with oral antihypertensive medications over 24–48 hours.

❌ BP is always higher.

✘ The severity of blood pressure elevation alone does not determine whether the condition is a hypertensive emergency or hypertensive urgency.

✘ A patient with a relatively lower blood pressure may still have a hypertensive emergency if target organ damage is present.

✘ The diagnosis depends on the patient's clinical findings, not just the blood pressure value.

❌ Requires hemodynamic monitoring.

✘ Hemodynamic monitoring may be required in some patients with a hypertensive emergency, especially those receiving intravenous antihypertensive therapy.

✘ However, this is part of the management rather than the feature that distinguishes it from hypertensive urgency.

✘ The defining characteristic remains the presence of acute target organ damage.

❌ Treated with rest and benzodiazepines.

✘ Rest and benzodiazepines may help lower blood pressure when anxiety is a contributing factor, but they are not the standard treatment for a hypertensive emergency.

✘ A true hypertensive emergency requires rapid but controlled blood pressure reduction using intravenous antihypertensive medications.

✘ Delaying appropriate treatment may lead to permanent organ damage or death.
