A patient's bedside ECG strips show the following changes
 
  increased PR interval; increased QRS width; and tall, peaked T waves. Vital signs are T 98.2  F; HR 118 beats/min; BP 146/90 mm Hg; and RR 18 breaths/min. The patient is receiving the following medications: digoxin 0.125 mg PO every day; D51/2 normal saline with 40 mEq potassium chloride at 125 mL/hr; Cardizem at 30 mg PO q8h; and aldosterone at 300 mg PO q12h. The physician is notified of the ECG changes. What orders should the nurse expect to receive?
 
  a. Change IV fluid to D51/2 normal saline and draw blood chemistry.
  b. Give normal saline with 40 mEq of potassium chloride over a 6-hour period.
  c. Hold digoxin and draw serum digoxin level.
  d. Hold Cardizem and give 500 mL normal saline fluid challenge over a 2-hour period.

  d. pressure support ventilation (PSV).

Question 6
