The nurse is caring for a client with a new diagnosis of asthma. Which teaching point should the nurse emphasize for proper inhaler use?

Choice A reason: Rebound tenderness in the right lower quadrant (McBurney’s point) is a hallmark of appendicitis, indicating peritoneal irritation from an inflamed appendix. This localized pain, elicited on palpation release, is highly specific, guiding urgent surgical evaluation to prevent rupture and peritonitis.

Choice B reason: Diffuse abdominal pain is nonspecific and occurs in various conditions, not uniquely appendicitis, which typically presents with localized right lower quadrant pain. Rebound tenderness is more diagnostic, as it directly reflects appendiceal inflammation, making it the priority finding.

Choice C reason: Decreased bowel sounds may occur in appendicitis due to ileus but are nonspecific, seen in other abdominal conditions. Rebound tenderness is more indicative, as it localizes to the appendix, confirming peritoneal irritation, critical for diagnosing acute appendicitis.

Choice D reason: Elevated blood pressure is not specific to appendicitis and may reflect pain or stress. Rebound tenderness directly indicates appendiceal inflammation, making it the most reliable finding, as it guides diagnosis and urgent intervention to prevent complications like perforation.

Choice A reason: Throat irritation is a common albuterol side effect due to its deposition in the oropharynx during inhalation. It is not life-threatening and can be managed with rinsing or spacer use. This does not require immediate intervention compared to cardiovascular effects, as it does not compromise vital organ function.

Choice B reason: Uncontrollable shaking (tremors) is a frequent albuterol side effect, resulting from beta-2 receptor stimulation in skeletal muscles. It is usually transient and benign, not requiring immediate intervention. Monitoring is sufficient unless severe, as it does not pose an acute threat compared to cardiac irregularities.

Choice C reason: An irregular rapid heart rate (tachycardia or arrhythmia) is a serious albuterol side effect, as beta-2 agonists can stimulate beta-1 receptors in the heart, causing cardiovascular instability. This warrants immediate intervention, as it risks cardiac compromise, especially in emphysema patients with compromised respiratory and cardiac reserves.

Choice D reason: Increased anxiety is a possible albuterol side effect due to its stimulatory effects on the central nervous system. While distressing, it is not immediately life-threatening. It requires monitoring but is secondary to cardiovascular complications, which pose a greater acute risk in emphysema patients with wheezing.
