Is it true or false that that APACHE II uses the following to obtain a risk stratification score?

True / False

Osmolality Correct

Serum creatinine Correct

Glasgow coma scale Correct

Haemoglobin concentration Incorrect answer selected

Serum lactate Incorrect answer selected

Explanation

The APACHE II scoring system was a modification of the original APACHE system. This update reduced the number of measured variables to 12, including the removal of lactate and osmolality.

Both the Glasgow coma scale (GCS) and serum creatinine are included in the APACHE II score, along with haematocrit. Haemoglobin concentration is not scored.

The other variables included are:

Temperature

Mean arterial pressure

Heart rate

Respiratory rate

Arterial pH

Oxygenation (A-a DO2 or PaO2)

Serum sodium

Serum potassium, and

White blood count.

The worst value for each physiological variable within the past 24 hours is used.
