PHARMACOLOGY EXAM 2 REVISED EDITION: STUDY GUIDE, EXAM PREPARATIONS, AND QUESTIONS AND ANSWERS Beta Blockers Cardioselective blocks beta 1 and non-cardioselective blocks beta 1 and 2 Atenolol blocks B1 only (cardioselective) and propranolol (non-cardioselective) blocks B1 & B2 For what conditions are beta-blockers used for Beta-blockers slow HR and decrease the force of contraction to make it easier for the heart to work, but there is some vasodilation, so there can be some hypotension. Make sure BP is ok, and resting HR is between 60-100. What do you do before you pick up the phone and call the doctor? Assess the patient, you must finish your nursing assessment. When you are looking at a test question, you will have some information in the stem of a question. There may be some assessment data in the stem of the question, but then look down at the choices and if you can choose one of those things that is completing your nursing assessment, that’s what you need to do. Before we can do ISBAR, we need all the information. You got to have all vital signs completed, all the subjective data, asking them questions. A question might not involve vital signs, but a laboratory value that you want to know before you call the doctor What are the two indications that professor laird gave for epinephrine? Anaphylaxis and cardiac arrest If somebody must have allergy testing or cardiac stress testing, what do we need to have them understand about beta-blocking therapy? The physician needs to take them off beta blockers for 48 hours before they have allergy testing and cardiac stress testing. It’s not hypotension, if they are beta blocked out, and they get anaphylaxis during allergy testing process or cardiac arrest during stress testing on treadmill, how well will the epinephrine work if someone is on full dose beta blockers. The idea is that they have the conversation with their prescriber and the prescriber can put them on something for 48 hours while they are off the beta blocker because we never want a patient to stop the beta blocker cold turkey, and the reason for that is they might have a rebound elevation of BP or may have rebound of cardiac angina or cardiac type chest pain.
