A 26-year-old female patient has arrived to the emergency room with signs of status asthmaticus. Which of the following drugs would you recommend for administration via nebulization?

Correct Answer: A

Rationale: In the scenario of a 26-year-old female presenting with signs of status asthmaticus, the recommended drug for nebulization is Albuterol (Option A). Albuterol is a short-acting beta agonist that acts quickly to relieve bronchospasm, a common feature of acute asthma exacerbations. Administering Albuterol via nebulization allows for rapid delivery of the medication directly to the lungs, providing prompt relief of airway constriction. Montelukast (Option B) is a leukotriene receptor antagonist that is used for long-term asthma management and prevention of asthma symptoms, but it is not suitable for acute exacerbations like status asthmaticus. Beclomethasone (Option C) is an inhaled corticosteroid used for long-term control of asthma symptoms and prevention of exacerbations. It is not indicated for immediate relief in acute situations like status asthmaticus. Magnesium sulfate (Option D) is sometimes used in the treatment of severe acute asthma exacerbations in the emergency setting, but it is typically administered intravenously, not via nebulization. In an educational context, understanding the appropriate use of respiratory medications is crucial for healthcare providers managing patients with asthma. Knowing which medications are indicated for acute exacerbations versus long-term control helps ensure optimal patient outcomes. Albuterol's rapid bronchodilatory effects make it the preferred choice for nebulization in acute situations like status asthmaticus.

Correct Answer: D

Rationale: The correct answer is option D) Small volume nebulizer with mouthpiece. Ipratropium bromide is a respiratory drug used to treat bronchospasm in COPD patients. A small volume nebulizer with a mouthpiece is the most appropriate method to deliver this medication to ensure effective inhalation therapy. The mouthpiece allows for direct delivery of the medication to the patient's airways, optimizing drug delivery and absorption. Option A) Dry powder inhaler is not suitable for delivering 2.5 mL of medication as it is designed for single-dose delivery and may not accommodate the required volume. Option B) Ultrasonic nebulizer with a mask is not the best choice as masks are often less efficient in drug delivery compared to mouthpieces, leading to potential medication wastage. Option C) Small volume nebulizer with a mask may be less effective than using a mouthpiece as it can lead to dispersion of the medication in the surrounding air rather than directly into the patient's airways. Educational Context: Understanding the appropriate delivery methods for respiratory medications is crucial for healthcare professionals caring for patients with respiratory conditions like COPD. Using the correct delivery device ensures optimal drug effectiveness and patient outcomes. By selecting the small volume nebulizer with a mouthpiece for ipratropium bromide in this scenario, healthcare providers can deliver the medication effectively and help manage the patient's bronchospasm.

Correct Answer: B

Rationale: In this scenario, the correct answer is B) Midazolam (Versed). This medication is a benzodiazepine that acts as a sedative and can help synchronize the patient's breathing with the ventilator. Benzodiazepines like midazolam are commonly used in ICU settings to provide sedation and manage agitation in mechanically ventilated patients. Option A) Fluoxetine (Prozac) is a selective serotonin reuptake inhibitor (SSRI) used to treat depression and other mental health conditions. It is not indicated for synchronizing breathing with a ventilator. Option C) Dextroamphetamine (Dexedrine) is a stimulant medication used to treat ADHD and narcolepsy. It does not have a role in synchronizing a patient's breathing with a ventilator. Option D) Cisatracurium (Nimbex) is a neuromuscular blocking agent that causes muscle paralysis, including respiratory muscles. While it can be used to facilitate mechanical ventilation by preventing patient-ventilator asynchrony in certain cases, it is not the best choice in this scenario where the patient is already breathing asynchronously. In an educational context, understanding the appropriate use of medications in critical care settings like the ICU is crucial for nursing students and healthcare professionals. Knowing when to use sedatives like midazolam to assist with ventilator synchrony can improve patient outcomes and prevent complications associated with ineffective ventilation support.

Correct Answer: B

Rationale: Ipratropium bromide is a medication commonly used in respiratory conditions such as asthma and COPD. The correct answer is B) Causes bronchodilatation because of its antagonistic effects at the cholinergic M₂/M₃ receptors. Ipratropium bromide is an anticholinergic drug that works by blocking acetylcholine receptors in the airways, leading to bronchodilation. This action helps to relieve bronchospasms and improve airflow in conditions like asthma and COPD. Option A) Is administered intravenously is incorrect because ipratropium bromide is usually administered via inhalation as a metered-dose inhaler or nebulizer, not intravenously. Option C) Has a more rapid onset of bronchodilatation than beta agonists is incorrect because beta agonists like albuterol typically have a faster onset of action compared to ipratropium bromide. Option D) Has a bitter taste is incorrect but is a common side effect of ipratropium bromide when inhaled. This taste is not related to its mechanism of action or effectiveness in causing bronchodilation. Understanding the mechanism of action of respiratory drugs like ipratropium bromide is crucial for healthcare professionals, especially pharmacists and nurses, to ensure safe and effective administration to patients with respiratory conditions. Knowing the correct administration route, onset of action, and common side effects helps in optimizing patient care and medication outcomes.

Correct Answer: C

Rationale: In this case, the correct answer is C) Nitrofurantoin. Pulmonary eosinophilia is a condition characterized by the accumulation of eosinophils in the lungs, often resulting from a hypersensitivity reaction. Nitrofurantoin, commonly used to treat urinary tract infections, is known to cause drug-induced pulmonary eosinophilia as a rare adverse effect. Option A) Methysergide is typically associated with pulmonary fibrosis, not pulmonary eosinophilia. Option B) Aspirin is not a common cause of pulmonary eosinophilia; instead, it is more commonly linked to asthma exacerbations in individuals with aspirin sensitivity. Option D) Carmustine (BCNU) is known for causing pulmonary fibrosis rather than pulmonary eosinophilia. Educationally, understanding the adverse effects of drugs is crucial for healthcare professionals to make informed decisions regarding medication management. Recognizing the specific side effects associated with various medications can aid in early detection, management, and prevention of potentially harmful outcomes for patients. This knowledge is especially important for pharmacology students preparing for exams like the NCLEX, where drug-related questions are common.
