A nurse is reinforcing teaching to a school-age child who has asthma. Which of the following medications should the nurse instruct the child to use to abort an ongoing attack?

Montelukast

Fluticasone

Cromolyn

Albuterol

Answer and Explanation

The Correct Answer is D

A) Montelukast:
Montelukast is a leukotriene receptor antagonist (LTRA) used as a controller or maintenance medication for asthma. It is not used for the immediate relief of asthma symptoms during an acute attack. Montelukast is taken regularly to prevent asthma symptoms and reduce the frequency of asthma attacks, but it does not provide rapid relief during an ongoing attack.

B) Fluticasone:
Fluticasone is an inhaled corticosteroid (ICS) used as a controller medication for asthma. It works by reducing airway inflammation and is taken regularly to control asthma symptoms and prevent exacerbations. Fluticasone is not used for the immediate relief of acute asthma symptoms and is not suitable for aborting an ongoing asthma attack.

C) Cromolyn:
Cromolyn is a mast cell stabilizer used as a controller medication for asthma. It helps prevent the release of inflammatory substances that contribute to asthma symptoms. Cromolyn is taken regularly to prevent asthma symptoms and reduce the frequency of asthma attacks but is not used for the immediate relief of acute asthma symptoms like albuterol.

D) Albuterol.
Albuterol is a short-acting beta agonist (SABA) bronchodilator used for the quick relief of asthma symptoms during an acute asthma attack or exacerbation. It works rapidly to relax the smooth muscles in the airways, opening them up and relieving bronchoconstriction, which improves airflow and alleviates symptoms such as wheezing, shortness of breath, and chest tightness. Albuterol is typically administered via inhalation through a metered-dose inhaler (MDI) or a nebulizer.

Correct Answer is ["10"]

Explanation

To administer the correct dose of valproic acid, which is 500 mg, when the available oral solution concentration is 250 mg per 5 mL, the nurse needs to calculate the volume of the solution required.

The calculation is as follows: (500 mg) / (250 mg/5 mL) = 2 x 5 mL = 10 mL.

Therefore, the nurse should administer 10 mL of the valproic acid oral solution to deliver a dose of 500 mg.

A. H2-receptor blockers B. Antacids C. Proton-pump inhibitors D. Antibiotics

Correct Answer is D

Explanation

A) H2-receptor blockers:
H2-receptor blockers, such as ranitidine and famotidine, are used to reduce the production of stomach acid. While they can provide symptomatic relief for ulcers by reducing acid secretion, they do not directly treat the underlying cause of the ulcer, which is the H. pylori infection.

B) Antacids:
Antacids are medications that neutralize stomach acid and can provide temporary relief from ulcer symptoms such as pain and discomfort. However, they do not eradicate the H. pylori bacteria or address the root cause of the ulcer. Antacids only provide symptomatic relief rather than treating the infection.

C) Proton-pump inhibitors:
Proton-pump inhibitors (PPIs), such as omeprazole and pantoprazole, are potent acid-suppressing medications that are commonly used to treat ulcers and gastroesophageal reflux disease (GERD). While they can help in ulcer healing by reducing acid secretion and providing symptomatic relief, they are not effective in eradicating H. pylori infection. PPIs are often used in combination with antibiotics for H. pylori eradication therapy, but they are not the primary treatment on their own.

D) Antibiotics.
H. pylori (Helicobacter pylori) is a bacteria that commonly infects the stomach lining and is a major cause of gastric and duodenal ulcers. Antibiotics are the primary treatment for H. pylori infection. The antibiotics kill the bacteria, allowing the ulcer to heal. Common antibiotics used to treat H. pylori include amoxicillin, clarithromycin, metronidazole, and tetracycline.
