HESI Med Surg 2 Q&A

HESI Med Surg 2 Q&A.The nurse should be correct in withholding a dose of digoxin in a client with congestive heart failure without specific instruction from the healthcare provider if the client's A) serum digoxin level is 1.5. B) blood pressure is 104/68. C) serum potassium level is 3. D) apical pulse is 68/min. - CORRECT ANSWER C) serum potassium level is 3. Hypokalemia (C) can precipitate digitalis toxicity in persons receiving digoxin which will increase the chance of dangerous dysrhythmias (normal potassium level is 3.5 to 5.5 mEq/L). The therapeutic range for digoxin is 0.8 to 2 ng/ml (toxic levels= >2 ng/ml); (A) is within this range. (B) would not warrant the nurse withholding the digoxin. The nurse should withhold the digoxin if the apical pulse is less than 60/min (D). During CPR, when attempting to ventilate a client's lungs, the nurse notes that the chest is not moving. What action should the nurse take first? A) Use a laryngoscope to check for a foreign body lodged in the esophagus. B) Reposition the head to validate that the head is in the proper position to open the airway. C) Turn the client to the side and administer three back blows. D) Perform a finger sweep of the mouth to remove any vomitus. - CORRECT ANSWER B) Reposition the head to validate that the head is in the proper position to open the airway. The most frequent cause of inadequate aeration of the client's lungs during CPR is improper positioning of the head resulting in occlusion of the airway (B). A foreign body can occlude the airway, but this is not common unless choking preceded the cardiac emergency, and (A, C and D) should not be the nurse's first action.
