A nurse is on their lunch break at a nearby table where two people are talking, laughing, and eating.
Suddenly the nurse hears one person say to the other: "Hey! Are you alright?" Which behavior signals a need to intervene for choking?

Choice A rationale

For a thoracentesis, the client is typically positioned sitting upright, often leaning forward over a bedside table. This position, which is a variation of Fowler's or orthopneic positioning, allows the ribs to expand and shifts the pleural fluid to the base of the pleural cavity. This makes the fluid more accessible for the physician to drain via the needle while minimizing the risk of accidental lung puncture, as the diaphragm is displaced downward by gravity.

Choice B rationale

The supine position, where the client lies flat on their back, is inappropriate for a thoracentesis. In this position, the pleural fluid spreads out along the posterior aspect of the lung, making it much harder to locate and safely aspirate a significant volume. Furthermore, lying flat can increase respiratory distress for a client who already has a pleural effusion, as the fluid puts more pressure on the lungs and reduces the available space for expansion.

Choice C rationale

The prone position, lying on the stomach, is not used for a bedside thoracentesis. This position would make it extremely difficult for the clinician to access the posterior or lateral chest wall where the procedure is typically performed. It would also severely compromise the client's ability to breathe comfortably during the procedure, as chest expansion is restricted against the bed surface, leading to increased anxiety and potential hypoxia during the invasive needle insertion.

Choice D rationale

The lithotomy position involves the client lying on their back with legs elevated in stirrups. This is used for pelvic, urological, or gynecological procedures and has no relevance to a thoracentesis. Placing a client with a pleural effusion in this position would provide no access to the thoracic cavity and would likely worsen their shortness of breath by increasing venous return to the heart and pushing abdominal contents against the diaphragm, further limiting lung volume.

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.
