Question

A nurse is planning to teach a community group about preventative measures for heart disease. Which of the following recommendations should the nurse include in the teaching plan? (Select All that Apply.)

Answer 1

Correct Answers:

Monitor blood pressure.
Lose weight if necessary.
Maintain current cholesterol level.

Rationale :

Monitor blood pressure

🔷 Regularly checking blood pressure is essential in early detection and management of hypertension, which is a major modifiable risk factor for heart disease.

🔷 Uncontrolled high blood pressure causes increased workload on the heart, leading to left ventricular hypertrophy and eventually heart failure or stroke.

🔷 Community education should emphasize checking BP at least annually, or more frequently if elevated.

Lose weight if necessary

🔷 Excess weight, especially central (abdominal) obesity, is associated with higher risks of hypertension, dyslipidemia, insulin resistance, and coronary artery disease (CAD).

🔷 Weight reduction improves cardiovascular outcomes, reduces LDL cholesterol and blood pressure, and improves glycemic control.

🔷 Encouraging BMI within normal range (18.5–24.9) and waist circumference goals can significantly reduce heart disease risk.

Maintain current cholesterol level

🔷 Maintaining normal cholesterol levels, particularly LDL < 100 mg/dL and HDL > 40 mg/dL, helps prevent atherosclerosis and plaque formation.

🔷 Even if cholesterol is currently within normal range, education should reinforce healthy dietary habits, regular screening, and lifestyle factors to maintain optimal lipid levels.

🔷 This is especially important for clients with a family history or other risk factors for heart disease.

Answer 2

Correct Answers:

Orthopnea

Rationale :

🔷 Orthopnea is a classic manifestation of heart failure in children, often presenting as difficulty breathing when lying flat due to pulmonary congestion.

🔷 In toddlers, this may be observed as restlessness at night, frequent waking, or preference for an upright position during sleep.

🔷 It occurs because left-sided heart failure leads to pulmonary venous congestion, resulting in dyspnea that worsens when supine.

🔷 Additional signs in pediatric heart failure may include tachypnea, poor feeding, diaphoresis with activity, and growth delays.

🔷 Recognizing orthopnea helps initiate timely interventions such as positioning, diuretics, and oxygen therapy.

Answer 3

Correct Answers:

Murmur
Weak pulses
Hypotension

Rationale :

Murmur

🔹 A systolic murmur is commonly heard in aortic stenosis due to turbulent flow across the narrowed aortic valve.

🔹 The murmur is usually crescendo-decrescendo and best heard at the right upper sternal border.

🔹 It is a hallmark finding during cardiac auscultation in valve disease, especially in pediatric assessments.

Weak pulses

🔹 Aortic stenosis leads to reduced blood flow through the aortic valve, resulting in diminished stroke volume.

🔹 This causes narrow pulse pressure and weak peripheral pulses, especially in the upper extremities.

🔹 It is an important circulatory finding indicating left ventricular outflow obstruction.

Hypotension

🔹 Due to obstruction of blood flow from the left ventricle, cardiac output is often impaired, leading to low systemic blood pressure.

🔹 In children, hypotension is a late but serious sign of decompensation and poor perfusion.

🔹 Early recognition can prompt interventions such as fluid support or inotropic agents.

Answer 4

Correct Answers:

Myoglobin.
Troponin T.
CK-MB.
Troponin I.

Rationale :

Myoglobin

🔹 Myoglobin is an early marker released into the bloodstream when muscle injury occurs, including cardiac muscle.

🔹 It appears within 2 hours of myocardial injury and peaks around 3–15 hours.

🔹 While not specific to cardiac tissue, it is useful for early detection of myocardial infarction (MI).

🔹 It helps in ruling out MI if levels remain normal after chest pain onset.

🔹 It is often used in combination with more specific markers like troponins for accurate diagnosis.

Troponin T

🔹 Troponin T is a cardiac-specific protein, highly sensitive and specific for myocardial cell damage.

🔹 It begins to rise within 3–6 hours after injury and can remain elevated for 10–14 days, aiding in late diagnosis.

🔹 Elevated levels confirm myocardial infarction, even in the absence of ECG changes.

🔹 It is one of the gold-standard markers for MI diagnosis in emergency settings.

🔹 Troponin testing is central in evaluating chest pain and suspected cardiac events.

CK-MB (Creatine Kinase-MB)

🔹 CK-MB is an enzyme found primarily in cardiac muscle, making it a moderately specific marker for MI.

🔹 Levels begin to rise 4–6 hours after myocardial injury, peaking around 24 hours, and return to baseline in 2–3 days.

🔹 It is useful for detecting reinfarction due to its short half-life compared to troponins.

🔹 Elevated CK-MB levels support a diagnosis of acute MI, especially when used with troponin.

🔹 Serial measurements can help determine evolving infarction patterns.

Troponin I

🔹 Troponin I, like Troponin T, is highly specific to myocardial tissue and sensitive to damage.

🔹 It elevates 3–6 hours after MI, peaks at 12–24 hours, and stays elevated up to 7 days.

🔹 It is used to differentiate cardiac from non-cardiac chest pain.

🔹 Persistent elevation is useful in detecting myocardial injury, especially in unstable angina.

🔹 Troponin I is preferred in clinical practice due to its specificity and diagnostic reliability.

Answer 5

Correct Answers:

Chronic cough
Sputum production
Dyspnea

Rationale :

Chronic cough

🟣 Chronic bronchitis, a form of COPD, presents with a productive cough lasting at least 3 months for 2 consecutive years.

🟣 The cough results from excess mucus production and airway inflammation.

🟣 This is often the first noticeable symptom in long-term smokers.

🟣 It reflects ongoing damage and irritation of airway linings.

Sputum production

🟣 COPD leads to hyperplasia of mucus-secreting glands, resulting in persistent sputum.

🟣 This symptom is most common in chronic bronchitis, a major subtype of COPD.

🟣 Sputum accumulation worsens airflow obstruction and increases infection risk.

🟣 Patients often report worsening sputum volume and color during exacerbations.

Dyspnea

🟣 Dyspnea, or shortness of breath, occurs due to air trapping and reduced gas exchange in COPD.

🟣 Patients often experience it initially during exertion, progressing to rest as disease advances.

🟣 It is linked to loss of alveolar elasticity and airflow limitation.

🟣 Dyspnea significantly reduces exercise tolerance and quality of life.

Answer 6

Correct Answers:

Bronchospasm occurs when there is Inflammation, edema, and excess mucus.

Rationale :

🟠 Bronchospasm is a key feature of asthma, triggered by inflammation and hypersensitivity of the airways.

🟠 When exposed to allergens or irritants, the airways narrow due to smooth muscle contraction, thick mucus production, and edematous swelling.

🟠 These changes cause airflow limitation, resulting in wheezing, chest tightness, and dyspnea.

🟠 Inflammatory mediators like histamines and leukotrienes further exacerbate bronchial narrowing.

🟠 Effective asthma management targets both inflammation and bronchospasm to restore airway patency.

Answer 7

Correct Answers:

Spironolactone

Rationale :

🟢 Spironolactone is a potassium-sparing diuretic that blocks aldosterone receptors in the distal nephron.

🟢 This leads to sodium excretion and potassium retention, putting patients at risk for hyperkalemia.

🟢 Simultaneously, it can cause hyponatremia due to excessive sodium loss, especially when combined with fluid restriction or other diuretics.

🟢 It is commonly used in heart failure to prevent cardiac remodeling but requires close monitoring of serum electrolytes.

🟢 Nurses must educate patients to avoid potassium-rich foods and salt substitutes while on this medication.

Answer 8

Correct Answers:

Smoking cigarettes
Diabetes mellitus
Family history of aneurysm

Rationale :

Smoking cigarettes

🔶 Smoking is the strongest modifiable risk factor for abdominal aortic aneurysm (AAA).

🔶 It contributes to vascular inflammation and degradation of the aortic wall, increasing aneurysm formation.

🔶 Toxins in tobacco damage the elastin and collagen in the arterial wall.

🔶 Smokers are significantly more likely to develop and experience rupture of an AAA.

Diabetes mellitus

🔶 Diabetes accelerates vascular degeneration and endothelial dysfunction, promoting aneurysm development.

🔶 Chronic hyperglycemia leads to inflammatory and structural changes in the arterial wall.

🔶 Although some studies suggest a paradoxically lower incidence of AAA in diabetics, diabetes still remains a recognized risk due to its effect on vascular health.

🔶 Management of blood sugar is essential to minimize cardiovascular complications.

Family history of aneurysm

🔶 A family history indicates a genetic predisposition to aneurysm formation.

🔶 First-degree relatives are at higher risk and may require early screening with abdominal ultrasound.

🔶 It reflects inherited structural weaknesses in the connective tissue of blood vessels.

🔶 Nurses should include family history in cardiovascular risk assessments.

Answer 9

Correct Answers

Blank 1 Correct Option: confirm the client is in cardiac arrest and call for help
Blank 2 Correct Option: begin CPR at rate of 30:2 compression to ventilation ratio

Rationale :

Confirm the client is in cardiac arrest and call for help

🟥 The first step in the Basic Life Support (BLS) protocol is to assess for unresponsiveness and absence of breathing or pulse.

🟥 The nurse should immediately confirm cardiac arrest by checking responsiveness and vital signs (which are absent at 1715).

🟥 Once cardiac arrest is confirmed, the nurse should call for help (activate emergency response system) without delay.

🟥 Early recognition and activation of help is critical to reduce time to CPR and defibrillation, improving outcomes.

🟥 In this case, the sudden unresponsiveness and absence of vital signs require immediate cardiac arrest protocol activation.

Begin CPR at rate of 30:2 compression to ventilation ratio

🟥 Following confirmation of cardiac arrest, the priority action is high-quality CPR, beginning with chest compressions.

🟥 According to American Heart Association (AHA) guidelines, CPR should be initiated at a 30:2 compression-to-ventilation ratio in adults when an advanced airway is not in place.

🟥 High-quality CPR is the most effective immediate intervention to restore circulation and oxygen delivery to vital organs.

🟥 Starting CPR promptly improves the chances of return of spontaneous circulation (ROSC) and survival.

🟥 Other interventions like airway support or defibrillation follow once compressions are initiated and additional help arrives.

Answer 10

Correct Answers:

Previous intubation due to status asthmaticus episode

Rationale :

🔴 A history of previous intubation due to status asthmaticus is the strongest predictor of future severe asthma exacerbations.

🔴 Status asthmaticus is a life-threatening condition characterized by unrelenting bronchospasm, often unresponsive to standard treatments.

🔴 Clients with this history often have more fragile airways, higher reactivity, and greater baseline inflammation.

🔴 These patients require more intensive monitoring and education on asthma action plans and early symptom recognition.

🔴 Past critical interventions like intubation are clinical red flags for high-risk asthma profiles.
