A client is diagnosed with hypertension. The nurse should prepare to instruct the client about which alpha2 agonists?
Standard Text: Select all that apply.
1. Methyldopa (Aldomet)
2. Clonidine (Catapres)
3. Tetrahydrozoline (Tyzine)
4. Midodrine (ProAmatine)
5. Pirbuterol (Maxair)
Correct Answer: 1,2
Rationale 1: Methyldopa (Aldomet) is an alpha2 agonist. It decreases blood pressure; the primary therapeutic application is the treatment of hypertension.
Rationale 2: Clonidine (Catapres) is an alpha2 agonist. It decreases blood pressure; the primary therapeutic application is the treatment of hypertension.
Rationale 3: Tetrahydrozoline (Tyzine) is widely used for minor eye irritation and redness.
Rationale 4: Midodrine (ProAmatine) is converted into an active metabolite that has alpha1-agonist actions. It is given orally for the symptomatic treatment of orthostatic hypotension.
Rationale 5: Pirbuterol (Maxair) is a short-acting beta-adrenergic agonist given by inhalation to terminate acute bronchospasm.
