What are known triggers for vaso-occlusive crises, such as Sickle Cell Disease?
Alkalosis and insomnia
Reduced stress and warm environmental temperature
Acidosis and dehydration
High fat diet and hyperoxia
The Correct Answer is C
A. Alkalosis and insomnia:
Alkalosis does not trigger sickling; acidosis (low pH) is more harmful. Insomnia alone is not a direct trigger.
B. Reduced stress and warm environmental temperature:
Reduced stress and warmth help prevent crises rather than cause them.
C. Acidosis and dehydration:
Acidosis promotes sickling of RBCs, and dehydration increases blood viscosity, both triggering vaso-occlusive crises.
D. High fat diet and hyperoxia:
A high-fat diet is linked to cardiovascular disease, and hyperoxia (excess oxygen) is not a trigger for sickling.

Explanation
A. Surgical emergencies cannot be excluded:
If there is a possibility of a surgical emergency (such as a ruptured ectopic pregnancy or an abscess), hospitalization is necessary for observation and treatment.
B. The patient uses no contraceptives:
While contraception use may affect the risk of PID, it doesn't directly determine whether hospitalization is needed.
C. The patient has a history of miscarriage:
A history of miscarriage is not a specific indication for hospitalization in PID cases.
D. The diagnosis is uncertain:
If PID is suspected but the diagnosis is uncertain, hospitalization may be required for further diagnostic workup and close monitoring.
E. There is a history of STIs:
A history of STIs increases the risk of PID but doesn't necessarily require hospitalization.
F. C-reactive protein levels are low:
C-reactive protein (CRP) is an inflammatory marker, but low levels do not indicate that hospitalization is not needed.
