Answer to Question 1
Correct Answer: 1
Rationale 1: Inhaled corticosteroids decrease inflammation, resulting in fewer asthma attacks.
Rationale 2: Beta 2 agonists are the most effective drugs for relieving acute bronchospasm, not preventing bronchospasm.
Rationale 3: Anticholinergics are alternative drugs used for clients who cannot tolerate short-acting beta agonists during an acute asthma attack.
Rationale 4: Systemic corticosteroids are used for short periods to reduce the frequency of acute asthma attacks.
Global Rationale: Inhaled corticosteroids are the drugs of choice for prevention of asthmatic attacks and for the management of chronic asthma. Oral corticosteroids are used for the short-term management of acute asthma attacks. Beta 2 agonists are the most effective drugs for relieving acute bronchospasm, not preventing bronchospasm. Anticholinergics are alternative drugs used for clients who cannot tolerate short-acting beta agonists during an acute asthma attack.
Answer to Question 2
Correct Answer: 2
Rationale 1: Cromolyn does not contain soy or peanut products.
Rationale 2: Ipratropium contains a substance derived from soya lecithin, so it is contraindicated in the presence of soy allergies.
Rationale 3: Triamcinolone does not contain soy or peanut products.
Rationale 4: Zafirlukast does not contain soy or peanut products.
Global Rationale: Ipratropium is contraindicated in patients with hypersensitivity to soya lecithin or related food products such as soybean and peanut. Soya lecithin is used as a propellant in the inhaler. Cromolyn, triamcinolone, and zafirlukast do not contain soy or peanut products.
