While caring for a client with a diagnosis of emphysema, the nurse instructs the client on positioning that will assist the client's ability to breathe when experiencing dyspnea.
Which position will the nurse instruct the client about?

Choice A rationale

Diarrhea is not a recognized or common adverse effect associated with the use of inhaled albuterol. Albuterol is a sympathomimetic agent that primarily targets beta-2 adrenergic receptors in the lungs to induce bronchodilation. While some systemic absorption can occur, its effects on the gastrointestinal tract do not typically manifest as increased motility or diarrhea. Gastrointestinal side effects are much more common with oral medications or different classes of drugs like certain antibiotics or magnesium-containing antacids.

Choice B rationale

Tachycardia is a well-documented adverse effect of albuterol because it is a sympathomimetic medication. Although albuterol is selective for beta-2 receptors in the bronchioles, at therapeutic or high doses, it can cross-react with beta-1 receptors located in the cardiac muscle. This stimulation increases the heart rate and force of contraction. A normal adult resting heart rate is 60 to 100 beats per minute. Clients may also experience palpitations or a fluttering sensation in the chest due to this.

Choice C rationale

While some clients might report a headache after using a bronchodilator, it is not the most definitive or physiologically significant adverse effect compared to cardiovascular changes. Headaches associated with albuterol are often secondary to transient changes in blood pressure or systemic vasodilation. However, tachycardia remains the primary concern for nursing monitoring because it directly reflects the drug's impact on the sympathetic nervous system and requires careful assessment of the client's cardiovascular stability during respiratory treatment.

Choice D rationale

Throat irritation can occur due to the mechanical delivery of the aerosol or the propellants used in the inhaler, but it is not a systemic pharmacological adverse effect of the albuterol molecule itself. While annoying, it does not represent the scientific mechanism of adrenergic stimulation. Rinsing the mouth after use is often recommended to alleviate this local sensation and prevent secondary issues, but it lacks the physiological clinical significance of the systemic beta-adrenergic responses like tremors or increased heart rate.

Choice A rationale

When using a bronchodilator and a corticosteroid together, the bronchodilator must be administered first to open the airways. This physiological sequence ensures that the subsequent corticosteroid, such as fluticasone, can penetrate deeper into the distal lung parenchyma for maximum anti-inflammatory effect. A waiting period of five minutes is standard to allow the bronchodilator to reach its peak local effect before the second medication is inhaled. This optimization is crucial for managing chronic respiratory diseases.

Choice B rationale

Using the fluticasone first is incorrect because the inflamed and constricted airways would limit the distribution of the steroid. If the airways are narrow, the medication particles are more likely to deposit in the upper throat and mouth rather than the lower bronchioles. Preparing the lungs requires the rapid relaxation of smooth muscle provided by a bronchodilator. Starting with a steroid inhaler would reduce the overall therapeutic efficacy of the combined treatment regimen.

Choice C rationale

While it is true that one should wait about one minute between puffs of the same medication to allow for better distribution, the most critical instruction in this specific scenario involves the sequence of two different classes of drugs. The instruction to wait five minutes between puffs of the same medication is helpful but does not address the priority of bronchodilation preceding steroid delivery. Therefore, this is not the most important piece of information for the nurse to include.

Choice D rationale

Rinsing the mouth is an essential step, but it must be done specifically after using the corticosteroid inhaler, not the albuterol inhaler. Fluticasone can cause local immunosuppression in the oral cavity, leading to the overgrowth of fungus. Rinsing after albuterol is not a standard requirement for preventing complications. The nurse should emphasize rinsing after the steroid to prevent oral candidiasis, making the instruction in this choice both inaccurate and of lower clinical priority.
