Q

how do you diagnose postural hypotension

A

check blood pressure whilst pateint is lying down and whilst standing up.

if you have a drop of 20 millimeters of mercury (mm Hg) in your systolic blood pressure or a drop of 10 mm Hg in your diastolic blood pressure within two to five minutes of standing then you have postural hypotension.

17
Q

what type of assesments of conscious levels are vital to recognize deteriorating patient

A

sequential assessments of conscious levels

18
Q

which condition is being described: a collection of blood in the ‘potential’ space between the skull and the outer protective lining that covers the brain (the dura mater). It usually occurs because of a head injury. It is a serious condition and emergency treatment is needed

A

An extradural haematoma

19
Q

which condition is being described: is a serious condition where blood collects between the skull and the surface of the brain. It’s usually caused by a head injury.

A

subdural haematoma

20
Q

Both epidural and subdural hematomas involve bleeding outside of the brain, how do they differ from one another

A

An epidural hematoma occurs when there is bleeding inside the skull but outside the dura membrane. … A subdural hematoma occurs when the bleeding exists inside the dura, but still outside the brain.

21
Q

what type of hemorrhage is this

A

extradural

22
Q

what type of hemorrhage is this

A

subdural hemorrhage

23
Q

what type of scans are used to diagnose intracranial bleeds

A

CT Scans

26
Q

when assessing conscious level, what scale is used for the assesment

A

the glasgow coma scale

Q

having low oxygen levels in your blood is called

A

hypoxemia

30
Q

aving low oxygen levels in your tissue is called

A

hypoxia
