NCLEX-RN Practice Questions 2023

The healthcare provider is performing an assessment on a patient who is taking propranolol (Inderal) for supraventricular tachycardia. Which assessment finding is an indication the patient is experiencing an adverse effect of this drug? Please choose from one of the following options. a. Dry mouth b. Bradycardia c. Urinary retention d. Paresthesia - Bradycardia - Propranolol is a nonselective beta-adrenergic antagonist. - Beta-1 receptors are found in the cardiac conduction system and myocytes. - Beta-1 blockade will slow discharge from the SA node and decrease speed through the AV node, slowing the heart rate. A patient experiencing ventricular tachycardia is given a medication which acts on the phase of the myocardial action potential indicated by the red "X." Which class of medication will the healthcare provider administer to the patient? a. Potassium channel blocker b. Adrenergic agonist c. Sodium channel blocker d. Sympathomimetic - Potassium channel blocker - The medication will decrease the heart rate and prolong the action potential and refractory period. - The dysrhythmia occurs during phase 3 of the action potential. - During phase 3 there is rapid repolarization when potassium leaves the cell, so a potassium channel blocker will be administered. A patient is being discharged after the insertion of a permanent pacemaker. Which statement made by the patient indicates an understanding regarding appropriate self-care? a. "Every morning I will perform arm and shoulder stretches." b. "Each day I'll take my pulse and record it in a log." c. "I'll have to get rid of my microwave oven." d. "I won't be able to use my electric blanket anymore." - "Each day I'll take my pulse and record it in a log." - Initially, patients should limit arm and shoulder activity on the operative side to prevent dislodgment of the pacing leads. - Microwave ovens and electric blankets will not adversely affect the pacemaker. - Tracking one's pulse can help the patient know if the pacemaker is working properly.
