Two drug stories meet in one older male patient: testosterone for low androgen, and the PDE-5 inhibitors (sildenafil, tadalafil) for erectile dysfunction. The PDE-5 drugs raise cGMP to relax vessels — and so do nitrates. Stack the two and blood pressure can collapse. Tap drug cards to build a patient's medication list, then watch the pressure gauge and read what the nurse must check.

Try it: with the PDE-5 inhibitor already on the list, add a nitrate and watch the pressure crash.
