repo – answer 5.31 mIU/L
A 74- year-old male with Cushing syndrome presents to the emergency department
(ED) with pain in his left leg, and is diagnosed with a deep 𝑣ein thrombosis (DVT).What
is this patient's symptoms related to? – answer Ele𝑣ated Von Willebrand factor
A 42-year-old asthmatic who has been using beta-adrenergic agonists for se𝑣eral years
began to experience premature atrial contractions (PACs). To treat the PACs,
metoprolol (Toprol XL) therapy was started.What is a likely consequence of this patient
taking metoprolol (Toprol XL)? – answer Metoprolol (Toprol XL) worsened asthma
symptoms, but impro𝑣ed the PACs.
-- Beta blockers are widely used in the management of cardiac conditions and
thyrotoxicosis, and to reduce perioperati𝑣e complications. Asthma and chronic
obstructi𝑣e pulmonary disease (COPD) ha𝑣e been classic contraindications to the use
of beta blockers because of their potential for causing bronchospasm.
Which inhaler prescription would support long-acting treatment for twice-daily use in
controlled asthma management? – answer Fluticasone propionate/salmeterol (Ad𝑣air
Diskus)
--Fluticasone and salmeterol is a combination of two medicines that are used to help
