A healthcare professional is educating a patient on asthma. The professional tells the patient that the most successful treatment for chronic asthma begins with which action?
Administration of broad spectrum antibiotics
Administration of drugs that decrease airway inflammation
Avoidance of the causative agent
Administration of drugs that reduce bronchospasm
The Correct Answer is C
A. Administration of broad-spectrum antibiotics: Broad-spectrum antibiotics are not a primary treatment for asthma, as asthma is an inflammatory condition and not primarily caused by bacterial infections. Antibiotics may be used for coexisting infections but are not the most successful initial treatment for chronic asthma.
B. Administration of drugs that decrease airway inflammation: While decreasing airway inflammation is important in managing asthma, the most successful long-term treatment begins with addressing the underlying causes and triggers. Reducing inflammation is part of the treatment strategy but is not the first action.
C. Avoidance of the causative agent: Avoiding the causative agent or trigger of asthma is the most successful initial treatment. Identifying and eliminating exposure to allergens or irritants, such as pollen, smoke, or pet dander, can significantly reduce the frequency and severity of asthma attacks, making it the foundational step in asthma management.
D. Administration of drugs that reduce bronchospasm: Medications that reduce bronchospasm, such as bronchodilators, are essential for immediate relief of asthma symptoms. However, they do not address the underlying inflammation and triggers, making avoidance of causative agents the most successful initial treatment for chronic asthma.

Correct Answer is ["C","F"]
Explanation
A. Fever: Fever is a common sign of pericarditis, often indicating inflammation or infection in the pericardial sac. This symptom is typical in patients with this condition.
B. Mild chest pain: Mild chest pain is a typical symptom of pericarditis. Patients often experience sharp, pleuritic chest pain that may worsen with inspiration or coughing.
C. No evidence of fatigue: Fatigue can be a common symptom in patients with pericarditis due to the body's response to inflammation. Therefore, the absence of fatigue is not typical, making this an appropriate choice.
D. Myalgias: Myalgias or muscle aches can occur in pericarditis as part of the systemic inflammatory response. This symptom is not unusual in patients with this condition.
E. Pericardial friction rub: A pericardial friction rub is a characteristic finding in pericarditis, heard during auscultation. It results from the movement of inflamed pericardial layers against each other.
F. Radiating substernal pain felt in the left shoulder: This type of radiating pain is more characteristic of myocardial ischemia or angina rather than pericarditis. While pericarditis can cause chest pain, it does not typically radiate in the same manner as that seen in cardiac conditions, making this an appropriate choice.
Correct Answer is D
Explanation
A. Hypoventilation causes hypocapnia: Hypoventilation leads to inadequate removal of carbon dioxide (CO₂), resulting in hypercapnia rather than hypocapnia. This occurs because decreased ventilation reduces gas exchange efficiency, allowing CO₂ to accumulate in the blood, which can cause respiratory acidosis.
B. Hypoventilation causes alkalosis: Hypoventilation leads to respiratory acidosis rather than alkalosis. When ventilation is insufficient, CO₂ builds up in the bloodstream, leading to an increase in hydrogen ion concentration and a subsequent drop in blood pH. This is commonly seen in conditions like chronic obstructive pulmonary disease (COPD), neuromuscular disorders, and opioid overdose.
C. Hyperventilation causes acidosis: Hyperventilation results in excessive elimination of CO₂, leading to a decrease in hydrogen ion concentration and an increase in blood pH, causing respiratory alkalosis rather than acidosis. Acidosis occurs when CO₂ retention leads to an increase in hydrogen ion concentration, which is the opposite of what happens with hyperventilation.
D. Hyperventilation causes hypocapnia: Hyperventilation leads to an excessive exhalation of CO₂, causing a reduction in blood CO₂ levels (hypocapnia). This can result in respiratory alkalosis, leading to symptoms such as dizziness, lightheadedness, tingling sensations, and even syncope. It is often seen in conditions like anxiety, panic attacks, fever, or high-altitude exposure.
