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 B

Explanation

A) A client who has a kidney stone:
Misoprostol is not contraindicated in clients who have kidney stones. Kidney stones are not a known contraindication for the use of misoprostol.

B) A client who is pregnant.
Misoprostol is a medication commonly used to prevent gastric ulcers in individuals who are taking nonsteroidal anti-inflammatory drugs (NSAIDs) for conditions such as osteoarthritis. However, it is contraindicated in pregnant women due to its potential to cause uterine contractions, leading to miscarriage or preterm labor. Misoprostol is classified as a pregnancy category X medication, meaning that there is clear evidence of fetal risk based on human or animal studies, and its use is contraindicated during pregnancy.

C) A client who has a urinary tract infection:
Misoprostol is not contraindicated in clients who have urinary tract infections. Urinary tract infections are not a known contraindication for the use of misoprostol.

D) A client who has osteoarthritis:
Misoprostol is commonly used in clients with conditions such as osteoarthritis to prevent NSAID-induced gastric ulcers. Osteoarthritis is not a contraindication for the use of misoprostol when indicated for gastric ulcer prevention in individuals taking NSAIDs.

A. Inspiration B. Expiration C. Respiration D. Perfusion

Correct Answer is D

Explanation

A) Inspiration:
Inspiration refers to the process of inhaling or breathing in air into the lungs. It involves the contraction of the diaphragm and expansion of the chest cavity, leading to the intake of air into the lungs.

B) Expiration:
Expiration, also known as exhalation, refers to the process of exhaling or breathing out air from the lungs. It involves the relaxation of the diaphragm and chest muscles, leading to the expulsion of air from the lungs.

C) Respiration:
Respiration is a broader term that encompasses both ventilation (the mechanical process of breathing) and gas exchange (the exchange of oxygen and carbon dioxide between the lungs and blood). While respiration involves both air movement and gas exchange, it does not specifically refer to blood flow through the lung, which is described by the term perfusion.

D) Perfusion.
Perfusion refers to the circulation of blood through the lung's blood vessels, including the pulmonary arteries and pulmonary capillaries. This process allows for the exchange of gases (oxygen and carbon dioxide) between the blood and the air in the lungs during respiration. Perfusion is essential for oxygenating blood and removing carbon dioxide, which is crucial for maintaining normal cellular function throughout the body.
