Which statement describes the action of a beta-adrenergic agent for a patient with a respiratory disorder such as asthma?

Bronchodilation.

Decrease in peak expiratory flow.

Thinner respiratory secretions.

Increase in respiratory rate.

Answer and Explanation

The Correct Answer is A

A.   Beta-adrenergic agents (often called bronchodilators) work by stimulating beta-2 adrenergic receptors in the airway smooth muscle, leading to relaxation of the muscles and dilation of the airways. This helps improve airflow and relieve symptoms of asthma.
B.   A beta-adrenergic agent should ideally increase peak expiratory flow (PEF) by dilating the airways and improving airflow, not decrease it.
C.   This is not a direct action of beta-adrenergic agents. While some medications (like mucolytics or certain expectorants) can thin secretions, beta-adrenergic agents primarily focus on bronchodilation and do not significantly affect the viscosity of respiratory secretions.
D.   While beta-adrenergic agents can sometimes cause mild tachycardia (increased heart rate) as a side effect, they are not intended to increase the respiratory rate directly. The primary goal of these medications is to improve airway patency rather than change the rate of breathing.

Correct Answer is ["A","B","D","E"]

Explanation

A. Rinsing the mouth and spitting after using a steroid inhaler is essential to prevent oral thrush, a common side effect of inhaled corticosteroids. This practice helps clear residual medication from the mouth and throat, reducing the risk of fungal infections.
B. Bronchodilators, such as short-acting beta-agonists (SABAs), should be used before steroid inhalers. The bronchodilator opens the airways, allowing the steroid to reach deeper into the lungs for better efficacy.
C. While some inhalers (like rescue inhalers) may be used on a PRN basis, steroid inhalers are typically prescribed for regular, daily use to manage inflammation and control chronic conditions like asthma or COPD. They are not intended for PRN use only.
D. Frequent oral hygiene helps to reduce the risk of oral thrush and other oral health issues associated with steroid use. Patients should be encouraged to maintain good oral hygiene practices while using inhaled steroids.
E. Holding the breath for about 10 seconds after inhalation allows for better medication absorption in the lungs. This practice helps maximize the efficacy of the inhaled medication.

A. Places a surgical mask on the patient to transport to radiology. B. Places the patient on droplet precautions. C. Wears a surgical mask when providing patient care. D. Places the patient in a private, negative airflow room. E. Wears eye protection when collecting sputum samples.

Correct Answer is ["A","D","E"]

Explanation

A. It is important to place a surgical mask on the patient when transporting them to minimize the risk of spreading TB droplets in the environment. This practice helps reduce transmission during transport.
B. TB is primarily transmitted via airborne particles, not droplets. Therefore, patients with active TB should be placed on airborne precautions, not droplet precautions. Airborne precautions include the use of specialized masks and a negative airflow room to prevent the spread of infectious aerosols.
C. While a surgical mask is not adequate for protecting healthcare workers from TB, they should wear a fitted N95 respirator or a powered air-purifying respirator (PAPR) when providing care to a patient with active TB. A surgical mask does not filter out the small particles that can carry TB bacteria.
D. Patients with active TB should be placed in a private room that has negative pressure ventilation. This design helps prevent airborne TB particles from escaping into other areas of the healthcare facility, protecting other patients and staff.
E. Eye protection is recommended when collecting sputum samples from a patient with active TB, as it helps protect against potential splashes of respiratory secretions that may contain infectious droplets. This is particularly important during procedures that may aerosolize the bacteria.
