Which side effect is noted as extremely rare but has occurred?

• A. Stroke (low risk, extremely rare, but has happened)
• B. Headache, tiredness, lowered blood pressure
• C. Vertebral and rib fractures (mostly in osteoporosis patients)
• D. Mild allergic reaction to latex

Answer: (A)

Stroke is the side effect described as extremely rare but has occurred because, in cervical spine manipulation, there is a very small risk of vertebral artery dissection that can lead to a stroke. This is an acknowledged but exceedingly uncommon complication, hence the phrasing. The other options describe effects that are either common and usually mild (headache, fatigue, transient low blood pressure) or injuries that are more likely in certain conditions (vertebral or rib fractures, especially with osteoporosis) or standard allergy risks (latex). So stroke best fits the description of being extremely rare yet having occurred.
