✍️ Sample NBRC Questions & Answers
1. Which drug is the first-line treatment for anaphylaxis causing severe bronchospasm?
Epinephrine is the first-line treatment for anaphylaxis because it rapidly reverses bronchospasm, hypotension, and angioedema through alpha and beta adrenergic receptor stimulation.
2. Which ventilator setting directly affects the rate of CO2 elimination?
CO2 elimination is directly proportional to alveolar minute ventilation; increasing respiratory rate or tidal volume increases CO2 clearance.
3. Extracorporeal membrane oxygenation (ECMO) provides gas exchange support by:
ECMO removes blood via cannula, passes it through an oxygenator membrane to add O2 and remove CO2, then returns oxygenated blood to the patient's circulation.
4. PEEP (positive end-expiratory pressure) is used primarily to:
PEEP maintains alveolar patency at end-expiration, recruits collapsed lung units, and improves V/Q matching and oxygenation.
5. Which of the following substances is a natural hormone produced by the pineal gland that induces sleep?
Melatonin is a natural hormone that induces sleep. All the others are medications classified as stimulants.
6. Which inhaled corticosteroid is most commonly used as maintenance therapy for persistent asthma?
Fluticasone (and other inhaled corticosteroids like budesonide and beclomethasone) is used as daily maintenance therapy for persistent asthma to reduce airway inflammation.
