A client with asthma receives a prescription for high blood pressure during a clinic visit. Which
prescription should the nurse anticipate the client to receive that is at least likely to exacerbate asthma?
Correct Answer- Metoprolol Tartrate( Lopressor)
The best antihypertensive agent for clients with asthma is metoprolol (Lopressor) (C), a beta2 blocking
agent which is also cardioselective and less likely to cause bronchoconstriction. Pindolol (A) is a beta2
blocker that can cause bronchoconstriction and increase asthmatic symptoms. Although carteolol (B) is a
beta blocking agent and an effective antihypertensive agent used in managing angina, it can increase a
client's risk for bronchoconstriction due to its nonselective beta blocker action. Propranolol (D) also
blocks the beta2 receptors in the lungs, causing bronchoconstriction, and is not indicated in clients with
asthma and other obstructive pulmonary disorders.
A male client who has been taking propranolol ( inderal) for 18 months tells the nurse the healthcare
provider discontinued the medication because his blood pressure has been normal for the past three
months. Which instruction should the use provide? Correct Answer- Ask the health care provider about
tapering the drug dose over the next week.
Although the healthcare provider discontinued the propranolol, measures to prevent rebound cardiac
excitation, such as progressively reducing the dose over one to two weeks (C), should be recommended
to prevent rebound tachycardia, hypertension, and ventricular dysrhythmias. Abrupt cessation (A and B)
of the beta-blocking agent may precipitate tachycardia and rebound hypertension, so gradual weaning
should be recommended.
A client who is taking clonidine ( Catapres, Duraclon) reports drowsiness. Which additional assessment
should the nurse make? Correct Answer- How long has the client been taking the medication
Drowsiness can occur in the early weeks of treatment with clonidine and with continued use becomes
less intense, so the length of time the client has been on the medication (A) provides information to
direct additional instruction. (B, C, and D) are not relevant.
