Which of the following ECG rhythms warrant immediate defibrillation?    A. Ventricular tachycardia B. Ventricular fibrillation C. Asystole D. Atrial fibrillation   34. AV blocks occur when the conduction of the impulse through the AV node is decreased. The following statements are true about AV blocks except?    A. First-degree AV block occurs when the atrial impulses are conducted at a slower rate. B. In second-degree block Type I, conduction shows increasing intervals until full blockage. C. In second-degree block Type II, PR interval is constant. D. Third-degree block occurs when no ventricular pulse is conducted. 35. Nurse May is operating a pacemaker with a NASPE-BPEG code. Which of the following is meant by the letter “D”?* A. Both the atrium and the ventricle have a pacing electrode in place. B. The pacemaker is sensing the activity of the ventricle only. C. The pacemaker is sensing the activity of the atrium only. D. The pacemaker’s stimulating effect is inhibited by ventricular activity. Situation – You are a newly employed nurse in the Central ICU. As part of your orientation, you should be familiarized with the emergency drugs needed in the ICU. The following questions apply. 36. As you scan through the emergency cart, you saw Dopamine. Recalling your undergraduate years, you remembered dopamine can serve as two functions: renal vasodilator and a vasopressor. Which dose would have an effect of renal vasodilation to patients?* A. 1-10 mcg/kg/min B. 2-20 mcg/kg/min C. 1-5 mcg/kg/min D. >20 mcg/kg/min 37. Your co-worker asked you some favor to re-compute for her the rate needed for her patient. In this way, she can verify that her computations were correct. The following details were given to you: Preparation: 200mg/5ml Total Volume:100ml Weight: 15 kg Dose: 2mcg/kg/min A. 4.5 ml/hr B. 5.5 ml/hr C. 6 ml/hr D. 7 ml/hr 38. Another nurse was testing your computation skills. She asked you to compute the dose of Dobutamine with the following details: Preparation: 250mg/20mL Total Volume: 100mL Weight: 15kg Rate: 1.8mL/hr A. 0.75 mcg/kg/min B. 0. 16 mcg/kg/min C. 0.25 mcg/kg/min D. 0.5 mcg/kg/min 39. Heparin is given to patient. The doctors order is to give 10,000 units/cc to be diluted to 115 ml diluent at a rate of 18 cc/hr. Compute for the dose to be given. A. 156 units/ml/hr B. 1565 units/ml/hr C. 1456 units/ml/hr D. 68888 units/ml/hr 40. Heparin concentration from the previous patient stated above is also needed. You as a nurse you compute an arrive at the correct answer which is? A. 1150 units B. 1180 units C. 158 units D. 87 units Situation – You are a nurse who works in the critical care unit setting and are required to cater to all sort of patients. 41. One of your patients has a pacemaker system implanted. This uses a bipolar epicardial lead system. What is true about this device? A. Contains positive and negative electrodes B. Contains only a negative electrode C. Implanted within the skin of the patient D. This has a wide sensing area 42. You notice that another patient is experiencing symptomatic bradycardia. You initiate giving atropine but the ECG reading still does not normalize. What can you do to attain an acceptable ECG reading from the patient? A. Recommend application of cardiac pacing to the physician B. Initiate transcutaneous cardiac pacing C. Prepare a defibrillator D. Call the physician immediately 43. Your patient is on temporary pacing. His pacing mode is described as synchronous with atrial and ventricular pacing, and ventricular sensing. Atrial and ventricular pacing are inhibited if there is spontaneous ventricular depolarization. What pacing mode is this? A. A00 B. D00 C. DVI
