I. The Case (& preliminary "hints")

Case - Headache, feeling hot, severe hypertension (and sweating)

II. Procedure

In the process of searching for the cause of Miss Nelson's hypertension, an alpha adrenergic blocker is administered IV and the resulting response of the blood pressure is monitored.

A] to locate the alpha blocker phenoxybenzamine

Using the Help section's Tips: How Do I? or Help Info on: (see below)

we locate information on phenoxybenzamine (below)

B] to administer the alpha blocker phenoxybenzamine

• we set our output tables as below:

• we administer a continuous dose for 1 hour

III. Output data

This administration of the blocker yields a sharp, immediate drop in both blood pressures (below).

IV. More

This ends the hints section, part 2, on this case.

You should attempt again at this point to arrive at a diagnosis and, where possible, a treatment. To do so

• Return to the HUMAN model's Physiology Lab section for this patient and verify

- the diagnosis by finding the appropriate variables to support your argument and

- the treatment by changing parameters so as to stabilize the patient.
