Examples of adverse events (AE) include which of the following?
A. Damaged wheelchair.
B. Anxiety.
C. Decreased blood sodium.
D. Enlarged thyroid on physical examination.
E. B, C, and D only.
F. All the above are adverse events (AEs).
The Correct Answer and Explanation is:
Correct Answer: E. B, C, and D only.
Explanation:
An adverse event (AE) is defined as any untoward medical occurrence in a patient or clinical investigation participant who has been administered a pharmaceutical product. It does not necessarily have a causal relationship with the treatment. AEs can be symptoms, signs, abnormal lab findings, or diseases, whether or not related to the drug.
Let’s evaluate each option:
- A. Damaged wheelchair – This is not considered an adverse event. Although it may negatively affect a patient’s experience or pose a safety risk, it is a device or equipment malfunction, not a medical occurrence or change in the patient’s health status. Therefore, it does not meet the criteria for an AE.
- B. Anxiety – Anxiety is a psychological symptom that affects a patient’s health status. If it occurs during a clinical trial or after receiving treatment, it qualifies as an AE even if it is not proven to be caused by the treatment.
- C. Decreased blood sodium – Also known as hyponatremia, this is a clinically significant laboratory abnormality. Such findings are explicitly included in the definition of an AE.
- D. Enlarged thyroid on physical examination – This is a new or worsening physical finding that could indicate an underlying pathological condition (e.g., goiter or thyroid disease). It is considered an AE if it occurs or is detected during the study period.
Hence, B, C, and D all represent medical events or abnormalities and qualify as AEs.
However, A (damaged wheelchair) is not a medical occurrence and thus does not qualify.
Conclusion: The correct answer is E. B, C, and D only, because these represent changes in a participant’s health status that meet the definition of adverse events.
