ATI PHARMACOLOGY PRACTICE QUESTIONS

1.A nurse is preparing to administer warfarin to a client who has a new onset of atrial fibrillation. The client asks the nurse, “What does this medication do?” Which of the following responses should the nurse make? a.“It helps your heart return to a normal rhythm.” b.“It dissolves blood clots.” c.“It can reduce your risk of having a stroke.” d.“It helps to prevent bleeding in atrial fibrillation.” Rationale: C. The nurse should identify that atrial fibrillation increases the client’s risk of having a stroke due to clot formation in the atrium. Warfarin can prevent clot formation when used long term, which will reduce the client’s risk of having a stroke. 2.A nurse is caring for a client who has diabetes insipidus. Which of the following laboratory values should the nurse identify as reflecting a contraindication to receiving vasopressin to treat this disorder? e.Sodium 152 mEq/L f.Potassium 6.0 mEq/L g.Creatinine clearance 50 mL/min h.Aspartate aminotransferase (AST) 52 units/L Rationale: C. Creatinine clearance should be above 87 mL/min for female clients and above 107 mL/min for male clients. A creatinine clearance of 50 mL/min indicates renal impairment and is a contraindication to receiving vasopressin. Renal impairment increases the likelihood of the life- threatening adverse effect of water intoxication 3.A nurse is reviewing the medication history of a client who has mild intermittent asthma. The nurse should anticipate a prescription for which of the following inhalers for the client? i.Ipratropium j.Albuterol sulfate k.Tiotropium l.Budesonide
