all the PCCN Exam questions with correct answers

all the PCCN Exam questions with correct answers The nurse observes that the patient's jugular veins distend in the semi-upright position to more than 5 cm above the sternal angle. This is an indication of: - Correct Answer ️️ -fluid volume overload. what is normal Pulmonary artery occlusion pressure (PAOP)? - Correct Answer ️️ -5- 12 mmHg The resistance against which the left ventricle must pump to eject its volume is: - Correct Answer ️️ -systemic vascular resistance. When the tricuspid valve is open, central venous pressure reflects the filling pressure in the: - Correct Answer ️️ -right ventricle. Tachycardia is dangerous for the patient with ischemic heart disease because of: - Correct Answer ️️ -compromised cardiac output. During initial examination of a critical care patient, the nurse observes wide and convex nails and bulbous fingertips. This is evidence of: - Correct Answer ️️ -central cyanosis. Priorities for palpation of the patient with cardiovascular disease include: - Correct Answer ️️ -estimating edema. checking capillary refill checking for DVT arterial pulses By blocking the conversion of angiotensin I to angiotensin II, angiotensin-converting enzyme inhibitors produce: - Correct Answer ️️ -b. vasodilation. The nurse has read that the cardiologist recommends the use of class IV drugs to depress sinus and atrioventricular node conduction and terminate supraventricular tachycardias in the patient at this time. The nurse will anticipate orders for which medications? - Correct Answer ️️ -a. Verapamil, diltiazem, or amlodipine The nurse has administered a drug that stimulates β1-adrenergic sites. Following administration of the drug, the nurse will assess for: - Correct Answer ️️ -a. increased heart rate. The nurse is observing the patient's electrocardiographic monitor after insertion of a temporary pacemaker. Seeing a P-wave after the pacing artifact, the nurse knows that the: - Correct Answer ️️ -c. atrium is being paced. The possibility of microshock when handling a temporary pacemaker can be minimized by: - Correct Answer ️️ -b. insulating the ends of the wires. and wearing gloves when handling the pacing wires In the postoperative cardiovascular patient, the most frequent cause of a decreased cardiac output is: - Correct Answer ️️ -a. reduced preload. A patient is being monitored by continuous electrocardiogram (ECG) after placement of a transvenous pacemaker. "Loss of capture" is seen on the ECG. Which nursing intervention may correct this situation? - Correct Answer ️️ -a. Position the patient on the left side. or reposition the leads In analyzing the ECG strip, the nurse notices a spike before each QRS complex. The patient's heart rate is 70 beats/min. This phenomenon is reflective of - Correct Answer ️️ -b. pacing artifact; the pacemaker is sensing and capturing. Calculate the cerebral perfusion pressure (CPP) for a patient with a mean arterial pressure (MAP) = 95 mm Hg and an intracranial pressure (ICP) = 15 mm Hg. - Correct Answer ️️ -b. 80 mm Hg What procedure secures an arteriovenous malformation when a pt's condition is too unstable for surgery? - Correct Answer ️️ -embolization that can be done to secure the lesion without surgery. When the condition is more stable, an operation might be considered if needed. Knowing that a patient has hypoxemia and ischemia in his brain, the nurse anticipates which of the following? - Correct Answer ️️ -a. Cerebrovascular dilatio
