This would cause symptoms such as hypertension (rather than hypotension), tachycardia (rather than bradycardia), tachypnea, diaphoretic skin, elevated temperatures, mydriasis (rather than miosis) and agitation. Rationale: Lysergic acid diethylamide (LSD) is a sympathomimetic drug and causes stimulation of the sympathetic nervous system. Failure of the pacemaker battery is more likely to cause the pacemaker to fail to pace (demonstrating pacing spikes not followed by QRS complexes) or to fail to sense (pacing spikes in or after QRS complexes). Increased pacemaker output is not generally associated with implanted pacemakers and would not show changes on the electrocardiogram. An exit block would appear as pacing spikes on the electrocardiogram without QRS complexes following the spikes. Rationale: Artifact at the baseline on the electrocardiogram of a patient with an implanted pacemaker is most commonly associated with external electrical interference such as electrocautery or magnetic resonance imaging. The decrease in respiratory rate and effort associated with myxedema coma is more likely to cause a respiratory acidosis rather than alkalosis. Bradycardia, rather than tachycardia and hypoglycemia rather than hyperglycemia are associated with the decreased metabolic states of myxedema coma. Decreased metabolism will cause a drop in core body temperature but the decrease in metabolism also suppresses shivering. Rationale: Myxedema coma is caused by decreased thyroid levels which decreases metabolism. That's why our CEN Exam Practice Questions include answer keys. It may sound obvious, but you have to know which questions you missed (and more importantly why you missed them) to be able to avoid making the same mistakes again when you take the real test.
