Q2 You suspect a patient might be suffering from a cardiac tamponade brought on by pericardial effusion. What makes you think this? 1. Elevation of the ST segment 2. Apparent electrical interference in the PR segment 3. Low-voltage QRS complexes that change shape from beat to beat 4. Evidence of Respiratory Sinus Arrhythmia but with more extreme heart-rate changes Q3 Premature Atrial Contractions, if not part of a couplet or triplet, are usually followed by an apparent ‘pause’. Why? 1. PACs cause temporary asystole 2. PACs have a higher voltage depolarization signal, and repolarization takes longer as a result 3. The heart initiates an electrical ‘restart’ to stop the PAC 4. The pacemaker’s “expected” activation happens during the refractory period, and is ignored Q4 What order do the “Three I’d Monsters” usually occur in? Physical injury causes ischemic reduction in blood flow, which eventually stops completely, leading to infarction Partial vessel occlusion causes ischemia, which in turn causes injury; eventual total occlusion leads to infarction Sudden infarction leads to permanent heart injury, ischemic pain will persist afterward They have absolutely no causal relationship to each other whatsoever Q5 A PVC is easily identifiable by its distinctive QRS complexes. Which of the following describes them? 1, Unusually narrow and tall, with inverted preceding P-wave 2, Unusually wide and strangely shaped, with no preceding P-wave 3, A normal P-wave is followed by three or more sequential, identical QRS complexes 4, An otherwise normal-looking QRS complex that occurs between the T and P-waves Q6 In some instances, someone might be denied a prescription for psychtropic medications because they have a “long QTc”. Why is this? 1, Psychotropics interrupt the QT interval, which can cause a multifocal ectopic rhythm 2, Psychotropics interrupt the QT interval, which can cause paroxysmal supraventricular tachycardia 3, Psychotropics further lengthen the QTc, which can cause a bradyasystolic rhythm 4, Pyschotropics further lengthen the QTc, which can cause Torsades de Pointes Q7 Which of these is a ‘privileged communication’? 1. Standard treatment modalities for specific conditions 2. Information about a patient (history, conditions, personal details, etc.) 3. The identities and roles of providers within a healthcare service 4. None of the above Q8 You have Mr. Doe sit on the exam table and remove his shirt so that you can apply the electrodes. You note that he has a lot of very thick chest hair. As a result, you decide to… …ask if you may shave his chest for electrode placement …shave his chest — you don’t need to ask …push chest hair aside as you place electrodes …place electrodes over chest hair — it won’t get in the way Please answer in this matter, ex: q1 ans 1.
