What is the therapeutic use of Albuterol?

Correct Answer: A

Rationale: Albuterol is a medication that belongs to the class of beta-2 adrenergic agonists, which are primarily used for bronchodilation. It works by relaxing the muscles in the airways, allowing them to widen and making breathing easier for individuals with conditions such as asthma, chronic obstructive pulmonary disease (COPD), and other respiratory disorders. Albuterol helps to relieve symptoms of bronchospasm, such as wheezing, shortness of breath, and chest tightness. It is commonly used as a rescue inhaler for quick relief of acute bronchospasm.

Correct Answer: C

Rationale: Packed red blood cells (RBCs) are used to treat anemia, a condition characterized by a low red blood cell count or hemoglobin level. Anemia can result from blood loss, chronic disease, or nutritional deficiencies. Thrombocytopenia and leukopenia involve low platelet and white blood cell counts, respectively, and are not treated with RBC transfusions. Hypoalbuminemia involves low albumin levels and requires albumin infusions, not RBCs. Therefore, anemia is the correct indication for this therapy.

Correct Answer: C

Rationale: Montelukast is commonly administered orally, which stands for "per os" meaning by mouth. This medication is available in tablet, chewable tablet, and oral granule formulations for easy ingestion. It is not administered intravenously (IV), intramuscularly (IM), or subcutaneously (SubQ) as it is primarily used for oral administration to treat asthma and allergic rhinitis.

Correct Answer: B

Rationale: The nurse's best response would be, "It takes 6 to 8 weeks to see a change in cholesterol levels." Statin drugs typically take around 6 to 8 weeks before a noticeable effect on serum cholesterol levels is seen. This timeframe allows the medication to fully take effect and lower the cholesterol levels in the blood. Patients should continue with the prescribed treatment regimen and have their cholesterol levels monitored regularly to assess the effectiveness of the medication.

Correct Answer: D

Rationale: Erectile dysfunction drugs like Viagra (sildenafil), Cialis (tadalafil), and Levitra (vardenafil) are contraindicated with Nitroglycerin. Both Nitroglycerin and erectile dysfunction drugs work by lowering blood pressure. When taken together, they can cause a significant drop in blood pressure leading to dizziness, fainting, and even serious complications like low blood pressure and decreased oxygen supply to the heart. Therefore, it is important to avoid using these medications together to prevent potential harm.
