There is a large surface area inside the lungs.

Inhaled medications are given at very high doses.

Inhaled medications are given with food.

There is a rich blood supply to the lungs.

Answer and Explanation

Correct Answer : A,B,E

A. The inside surface of the lungs is small, and the dose is concentrated in that area: Inhalation medications are delivered directly to the lungs, where they are rapidly absorbed due to the small surface area and the close proximity of the medication to the lung tissue.

B. There is a large surface area inside the lungs: The lungs have a large surface area for gas exchange, allowing for efficient absorption of inhaled medications into the bloodstream.

C. Inhaled medications are given at very high doses: Inhaled medications are typically given at therapeutic doses appropriate for the patient's condition. While they may be given in higher doses compared to oral medications in some cases, the dosage is carefully adjusted based on factors such as the patient's age, weight, and severity of the condition.

D. Inhaled medications are given with food: Inhaled medications are typically administered separately from meals. Food can interfere with the absorption of inhaled medications and may affect their effectiveness.
E. There is a rich blood supply to the lungs: The lungs have a rich network of blood vessels, known as pulmonary capillaries, which allows for rapid absorption of inhaled medications into the bloodstream.

Correct Answer is D

Explanation

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.

A. Low-back pain B. Fever C. Dyspnea D. Urticaria

Correct Answer is D

Explanation

A) Low-back pain:
Low-back pain is not a common manifestation of an allergic reaction to a blood transfusion. It may be associated with other conditions, such as musculoskeletal issues or renal complications, but it is not typically addressed by diphenhydramine administration during transfusion.

B) Fever:
While fever can occur as a manifestation of an adverse reaction to a blood transfusion, it is more commonly associated with non-allergic transfusion reactions such as transfusion-related acute lung injury (TRALI) or bacterial contamination of the blood product. Diphenhydramine is not specifically indicated for the prevention of fever during transfusion.

C) Dyspnea:
Dyspnea, or difficulty breathing, can occur as a manifestation of a severe allergic reaction or anaphylaxis during a blood transfusion. However, diphenhydramine alone may not be sufficient to prevent or treat severe respiratory symptoms associated with anaphylaxis. In such cases, prompt medical intervention and administration of epinephrine may be necessary. Diphenhydramine primarily targets histamine-mediated symptoms such as urticaria and itching.

D) Urticaria.
Urticaria, commonly known as hives, is a skin reaction characterized by raised, itchy welts that can occur as a result of an allergic or hypersensitivity reaction. During a blood transfusion, if the recipient's immune system reacts to foreign proteins in the transfused blood, it can lead to an allergic reaction characterized by symptoms such as urticaria, itching, flushing, and sometimes more severe reactions like anaphylaxis.
Diphenhydramine is an antihistamine medication that works by blocking the effects of histamine, a chemical released by the body during allergic reactions. By administering diphenhydramine before the blood transfusion, the nurse aims to prevent or minimize the occurrence of urticaria and other allergic symptoms.
