Which scenario can be considered as an adverse effect of medication?

The scenario where a resident develops a severe skin rash is considered an adverse effect of medication because it signifies a significant and potentially harmful reaction to the medication. Adverse effects are unintended and often harmful reactions that occur as a result of taking a medication. A severe skin rash can be indicative of an allergic reaction or other serious complications that may require medical attention and intervention. Such reactions can range from mild to life-threatening, making it essential for medication administration personnel to identify and report them promptly.

In contrast, other scenarios provided involve reactions that do not signal serious harm. A mild headache, temporary drowsiness, and increased energy can be typical responses to medication and may not necessarily indicate a harmful outcome. These responses could be side effects but do not reflect the same level of urgent concern as a severe skin rash. Understanding the distinction between normal side effects and adverse effects is crucial for ensuring patient safety and effective medication management.
