A client likely to experience hypo- or hyper-glycemia has:

Hypertension, or high blood pressure, primarily involves the cardiovascular system and is not directly linked to blood glucose levels. While hypertension can co-occur with diabetes, it does not cause fluctuations in blood sugar, and individuals with hypertension may not experience hypo- or hyper-glycemia as a primary concern.

Multiple sclerosis (MS) is a neurological condition that affects the central nervous system. While it can lead to various symptoms, MS does not specifically influence blood sugar levels or predispose individuals to hypo- or hyper-glycemia. Thus, it is not a relevant condition for glucose regulation issues.

Parkinson’s disease is a progressive neurological disorder that primarily affects movement and coordination. Similar to MS, it does not directly impact blood glucose control. Patients with Parkinson's may have other health concerns, but hypo- or hyper-glycemia is not a typical issue associated with this condition.
