Question 1 See full question A client is scheduled to have a graded exercise test. The nurse explains to the client that the test will determine how: You Selected: well the body reacts to controlled exercise stress. Correct response: well the body reacts to controlled exercise stress. Explanation: Graded exercise testing is a diagnostic and prognostic tool used to determine the physiologic responses to controlled exercise stress. Information gained from a graded exercise test can achieve diagnostic, functional, and therapeutic objectives for the client. Graded exercise tests involve the use of a treadmill, stationary bicycle, or arm ergometry. The information obtained from this test is not used to set the incline on the treadmill, and measuring the distance walked and the duration of the walk are not the purpose of a graded exercise test. Remediation: Electrocardiography, exercise Question 2 See full question A nurse should include which discharge instruction for clients receiving tricyclic antidepressants? You Selected: Restrict fluid and sodium intake while using this medication. Correct response: Don't consume alcohol while using this medication. Explanation: Drinking alcohol can potentiate the sedating action of tricyclic antidepressants. Dry mouth and blurred vision are normal adverse effects of tricyclic antidepressants. Fluid and sodium intake must be monitored during lithium treatment, not during treatment with tricyclic antidepressants. Safe use of tricyclic antidepressants during pregnancy and breast-feeding hasn't been established. Remediation: Amitriptyline hydrochloride Clomipramine hydrochloride Question 3 See full question The nurse prepares to administer promethazine 35 mg IM as prescribed PRN for a client with cholecystitis who has nausea. The ampule label reads that the medication is available in 25 mg/mL. How many milliliters should the nurse administer? Record your answer using one decimal place. Your Response: 0.7 Correct response: 1.4 Explanation: The following formula is used to calculate the correct dosage: 35 mg/X = 25 mg/1 mL X = (35/25) mL X = 1.4 mL.
