Correct Answer: A. Control fluid balance

Explanation:

Heart failure exacerbations in older adults are most commonly triggered by fluid overload, leading to symptoms such as shortness of breath, swelling in the legs, and weight gain. Controlling fluid balance is the primary goal to prevent hospital readmissions. This includes adhering to prescribed diuretics, monitoring daily weight, restricting sodium intake, and educating patients on early warning signs of fluid retention. Proper fluid management reduces congestion in the lungs and prevents worsening heart failure symptoms, which significantly decreases the frequency of hospitalizations.

Why the Other Options Are Incorrect:

B. Control blood pressure

While managing hypertension is important in preventing heart failure progression, it is not the most immediate concern in reducing hospitalizations due to acute exacerbations. Many patients with heart failure already experience low or fluctuating blood pressure, making fluid balance a higher priority in acute management. Blood pressure control is a long-term strategy for heart failure management, but it does not directly prevent acute decompensations that lead to hospitalization.

C. Prevent deconditioning

Deconditioning, or muscle weakening due to inactivity, is a concern in chronic heart failure management, but it is not the primary cause of hospital admissions. Encouraging activity is important for overall well-being, but patients experiencing acute heart failure symptoms often need to prioritize fluid balance before engaging in physical activity. Fluid overload causes breathlessness and fatigue, making exercise difficult; thus, addressing fluid retention first is essential before focusing on physical activity.

D. Maintain patient safety

Ensuring patient safety is always a priority, but it does not directly reduce hospitalizations for heart failure exacerbations. Safety concerns, such as fall prevention and medication adherence, are important in general care but do not target the primary issue causing acute exacerbations, which is fluid overload. Managing fluid balance has a more direct impact on hospital admission rates than general safety measures.

Summary:

The most important goal in reducing hospitalizations for heart failure exacerbations in older adults is controlling fluid balance. Fluid retention leads to worsening symptoms, pulmonary congestion, and hospital admissions. Managing fluid balance through diuretics, sodium restriction, daily weight monitoring, and patient education is the most effective strategy to prevent acute decompensations. While blood pressure control, physical activity, and patient safety are important, they do not directly address the main cause of frequent hospitalizations, which is fluid overload. Therefore, controlling fluid balance is the most critical nursing intervention for reducing hospital readmissions in older adults with heart failure.

Three Findings That Require Immediate Follow-Up

A. Decreased lung sounds

B. Heart rate of 110 per minute

D. Subcutaneous emphysema

Explanation

A thoracentesis is a procedure in which fluid is removed from the pleural space to improve breathing and diagnose underlying conditions. While it is generally safe, complications such as pneumothorax, bleeding, or infection can occur. The nurse must closely monitor for any signs of distress or worsening respiratory function.

A. Decreased Lung Sounds - Requires Immediate Follow-Up

Diminished or absent lung sounds after thoracentesis can indicate pneumothorax, re-accumulation of fluid, or lung collapse. Since this patient has a history of frequent pleural effusions and lung cancer, the risk of complications is higher. The nurse should assess the patient further and notify the provider immediately.

D. Subcutaneous Emphysema - Requires Immediate Follow-Up

Subcutaneous emphysema is the presence of air trapped under the skin, often caused by air leaking from the lungs into the surrounding tissues. This can indicate a lung injury or pneumothorax following the thoracentesis. The nurse should monitor for increasing swelling or crepitus and ensure the patient is not developing respiratory distress.

B. Heart Rate of 110 per Minute - Requires Immediate Follow-Up

An elevated heart rate (tachycardia) can be an early sign of hypoxia, respiratory distress, or even tension pneumothorax. Since the patient had a thoracentesis, tachycardia may indicate worsening respiratory function, fluid imbalance, or stress on the cardiovascular system. Immediate assessment is needed to rule out serious complications.

Why the Other Options Do Not Require Immediate Follow-Up

C. Oxygen Saturation of 95 Percent - Does Not Require Immediate Follow-Up

An oxygen saturation of 95 percent is within normal limits and suggests that the patient is maintaining adequate oxygenation. No immediate intervention is required at this time.

E. Trachea Midline - Does Not Require Immediate Follow-Up

A midline trachea is a reassuring sign, as tracheal deviation can indicate a tension pneumothorax or severe respiratory distress. Since the trachea is in the expected position, there is no urgent concern related to this finding.

F. Puncture Site Dry - Does Not Require Immediate Follow-Up

A dry puncture site indicates that there is no active bleeding or drainage from the thoracentesis site. While the site should continue to be monitored for signs of infection, it does not require immediate follow-up.

Summary

The three findings that require immediate follow-up are decreased lung sounds, subcutaneous emphysema, and a heart rate of 110 per minute. These findings may indicate complications such as pneumothorax, lung injury, or respiratory distress. The nurse should assess the patient further, monitor for worsening symptoms, and notify the provider as needed.

The correct answer is: D) Bronchospasms

Rationale:

Bronchospasms are a serious complication of a bronchoscopy and can indicate airway obstruction or respiratory distress. This requires immediate intervention to ensure the airway remains open and the client can breathe properly. The nurse should report this finding to the provider immediately.

Why the Other Options Are Incorrect:

Blood-tinged sputum:

This is a common and expected finding after a bronchoscopy due to minor irritation of the airway. It is not usually a cause for concern unless it becomes excessive or persistent.

Dry, nonproductive cough:

A mild cough is expected after the procedure due to throat irritation from the bronchoscope. It should resolve on its own.

Sore throat:

A sore throat is a common side effect due to irritation from the bronchoscope. It can be managed with lozenges or warm fluids.

Key Takeaway:

The nurse should immediately report bronchospasms to the provider, as this can indicate airway obstruction or respiratory distress, which requires prompt intervention.

Correct Answer: C. Crushing chest pain

Rationale:

Classic "crushing" chest pain is often absent in older adults experiencing an acute myocardial infarction (AMI) Instead, older adults, especially men, may present with atypical symptoms, such as:

Vague complaints (e.g., weakness, confusion, dizziness)

Epigastric discomfort (burning or indigestion-like pain)

Dyspnea (shortness of breath) and fatigue

Because of these atypical presentations, AMI in older adults is often underdiagnosed or delayed in treatment, increasing the risk of complications.

Why the Other Options Are Incorrect:

A. Vague complaints

Older adults often present with vague symptoms like weakness, nausea, dizziness, or confusion rather than classic chest pain.

B. Epigastric burning

Gastrointestinal symptoms like epigastric burning or indigestion are common atypical presentations of AMI in older adults.

D. Dyspnea and fatigue

Older adults frequently experience dyspnea and fatigue instead of chest pain during an AMI, making diagnosis more challenging.

Key Takeaway:

In older adults, AMI may not present with "classic" crushing chest pain. Instead, symptoms like fatigue, shortness of breath, dizziness, or gastrointestinal discomfort may be more prominent. Nurses and clinicians should recognize these atypical signs to ensure timely diagnosis and treatment.

Correct Answer: B. Prednisone

Rationale:

Prednisone is a corticosteroid that helps manage chronic asthma by reducing inflammation and suppressing the immune response in the airways. It is typically used for long-term control in severe asthma or during acute exacerbations to decrease airway swelling and mucus production.

Why the Other Options Are Incorrect:

A. Albuterol

A short-acting beta-agonist (SABA) used for quick relief of acute asthma symptoms (rescue inhaler). Does not reduce inflammation—it works by relaxing bronchial smooth muscles to improve airflow. Not for long-term inflammation control.

C. Theophylline

A methylxanthine that relaxes airway muscles and improves breathing but is less commonly used due to its narrow therapeutic range and potential side effects (toxicity, arrhythmias). Does not directly reduce inflammation like corticosteroids.

D. Ipratropium

An anticholinergic bronchodilator used primarily for chronic obstructive pulmonary disease (COPD) rather than asthma. Sometimes used in acute asthma exacerbations, but not a first-line treatment for chronic asthma.

Key Takeaway:

For chronic asthma, inhaled corticosteroids (ICS) like budesonide or fluticasone are preferred for long-term control. Prednisone, an oral corticosteroid, is often used for short-term management of severe asthma exacerbations.

Correct Answer: C. Pericarditis

Rationale:

Pericarditis is the inflammation of the pericardium, the thin, double-layered membrane surrounding the heart. It can be caused by viral infections, bacterial infections, autoimmune disorders, myocardial infarction (Dressler’s syndrome), or chest trauma.

Common Symptoms of Pericarditis:

Sharp, pleuritic chest pain (worse with inspiration or lying flat, relieved by sitting up and leaning forward)

Pericardial friction rub (high-pitched, scratchy sound heard with a stethoscope)

ST-segment elevations in multiple ECG leads (without reciprocal changes)

Fever and tachycardia in infectious cases

Why the Other Options Are Incorrect:

A. Endocarditis

Inflammation of the endocardium (inner lining of the heart), usually due to bacterial infection (infective endocarditis). Symptoms: Fever, heart murmurs, Janeway lesions, Osler’s nodes, Roth spots.

B. Myocarditis

Inflammation of the myocardium (heart muscle), often due to viral infections. Symptoms: Fatigue, chest pain, arrhythmias, heart failure symptoms.

D. Cardiomyopathy

Disease of the heart muscle causing weakened cardiac function. Symptoms: Heart failure, dyspnea, arrhythmias, fluid retention.

Key Takeaway:

​​​​​​​Pericarditis is inflammation of the pericardial sac, typically causing pleuritic chest pain relieved by sitting up and a pericardial friction rub on auscultation. It requires NSAIDs, colchicine, or corticosteroids, and in severe cases, pericardiocentesis if there is a pericardial effusion leading to tamponade.

Correct Answer: D. ST-segment elevation

Rationale:

ST-segment elevation on an electrocardiogram (ECG) is the most indicative finding of an acute myocardial infarction (MI), specifically a ST-elevation myocardial infarction (STEMI). It occurs due to complete occlusion of a coronary artery, leading to myocardial ischemia and injury.

Other ECG Changes Associated with MI:

Inverted T waves: Indicate ischemia but are not as specific for an acute MI as ST elevation.

Pathologic Q waves: Suggest previous or evolving infarction.

Why the Other Options Are Incorrect:

A. Prolonged PR interval

Indicates first-degree heart block, which affects AV node conduction but is not indicative of an MI.

B. Peaked P waves

Suggest right atrial enlargement (e.g., pulmonary hypertension, chronic lung disease) but are not associated with MI.

C. Inverted T waves

Indicate ischemia but are not the most definitive sign of an MI. T-wave inversions may also be seen in other conditions like pericarditis or electrolyte imbalances.

Key Takeaway:

ST-segment elevation is the most significant ECG indicator of an acute myocardial infarction (STEMI) and requires immediate intervention to restore coronary blood flow (e.g., PCI or thrombolytics)

The correct answer is: B Respiratory alkalosis

Rationale:

The client is experiencing high anxiety and rapid, shallow respirations (30/min), which indicate hyperventilation. Hyperventilation leads to excessive exhalation of CO₂, causing a decrease in carbonic acid (H₂CO₃) and an increase in blood pH (alkalosis). Respiratory alkalosis occurs when CO₂ levels drop due to rapid breathing, leading to an increase in blood pH (alkaline state).

Why the Other Options Are Incorrect:

Respiratory Acidosis:

Caused by hypoventilation (slow or inadequate breathing), leading to CO₂ retention and low pH (acidic state). This client is hyperventilating, which would cause CO₂ loss, not retention.

 Metabolic Alkalosis:

Caused by excessive loss of acids (e.g., vomiting, diuretic use) or excessive bicarbonate (HCO₃) retention. This condition is not related to respiratory changes but rather metabolic causes like prolonged vomiting or excessive antacid use.

 Metabolic Acidosis:

Caused by excess acid production (e.g., diabetic ketoacidosis, lactic acidosis, renal failure) or bicarbonate loss (e.g., severe diarrhea). This client’s symptoms are related to hyperventilation, which does not align with metabolic acidosis.

Key Takeaway:

 Hyperventilation → CO₂ loss → Increased pH → Respiratory Alkalosis

 Common causes: Anxiety, panic attacks, fever, pain, high altitude, early stages of sepsis

Intervention: Encourage slow, controlled breathing (e.g., breathing into a paper bag) to retain CO₂ and restore acid-base balance.

Correct Answer: B. Decrease heart rate

Rationale:

Beta-blockers work by blocking beta-adrenergic receptors, specifically beta-1 receptors in the heart. This leads to:

Decreased heart rate (negative chronotropic effect)

Reduced myocardial contractility (negative inotropic effect)

Lowered blood pressure due to decreased cardiac output

Beta-blockers are commonly used for hypertension, angina, heart failure, and arrhythmias. Examples include metoprolol, atenolol, and propranolol.

Why the Other Options Are Incorrect:

A. Increase heart rate: Beta-blockers do the opposite; they reduce heart rate by blocking sympathetic stimulation.

C. Increase blood pressure: Beta-blockers lower both heart rate and blood pressure, making this choice incorrect.

D. Increase cardiac output: Beta-blockers reduce cardiac output by decreasing heart rate and contractility, so this answer is incorrect.

Key Takeaway:

Beta-blockers slow the heart rate and lower blood pressure, making them effective for treating hypertension and heart-related conditions.
