CCRN QUESTIONS WITH CORRECT

ANSWERS UPDATED 2024


The nurse is caring for a patient with acute inferior wall MI, post-coronary artery stent deployment, For

optimal care of the patient, the nurse should: - ANSWER✔✔-Continuously monitor the patient in lead II




It is best practice to monitor the patient status post PCI with stent, in the lead that was most abnormal

during the acute occlusion.


The ECG demonstrates ST elevation in leads II, III and aVF. The nurse needs to monitor the patient closely

for which of the following? - ANSWER✔✔-Complication likely to occur after an acute inferior wall MI

include bradycardia secondary to ischemia to the SA and/or AV node, and papillary muscle rupture or

dysfunction due to the anatomical distance between the RCA and the papillary muscle.


Which of the following hemodynamic profiles would benefit from the aggressive fluid administration,

pressers and antibiotics therapy?




a. RAP: 1mm Hg; PAOP: 4 mmHg; SVR: 1800 dynes/sec; CO: 2L/min




b. RAP: 5; PAOP: 7; SVR: 400; CO; 8L - ANSWER✔✔-B. the hemodynamic profile of RAP 5, PAOP 7, SVR

400 is typical of septic shock, and choice B would be the best approach.

Which of the following is indicative of a mixed acid-base disorder?




A. pH 7.18; PaCO2 25; PaO2 64; HCO3 11




B. pH 7.33; PaCO2 29; PaO2 72; HCO3 15 - ANSWER✔✔-The decrease in PaCO2 is evidence of respiratory

alkalosis and the decreased HCO3 is evidenced of a metabolic acidosis. The pt with severe sepsis or

septic shock may present with this mixed acid-base disorder.


The patient with a temporary pacemaker develops pacemaker malfunction. The oriented is instructed to

reposition the patient to try and correct the problem. The cardiac monitor most likely demonstrates? -

ANSWER✔✔-Failure to capture (pacemaker without a QRS) may be corrected by repositioning the

patient to the side.


The patient with diastolic heart develops SVT, heart rate 220/min. The most dangerous hemodynamic

effect is a decrease in: - ANSWER✔✔-coronary artery perfusion.




Diastolic heart failure results in a problem with left ventricular FILLING secondary to ventricular

thickening, and contractility and ejection are maintained in diastolic failure. The rapid heart rate will

decrease filling time, worsen left ventricular filling and because coronary artery perfusion occurs during

diastole, this arrhythmia may be life-threatening.


The patient is receiving heparin infusion for the treatment of pulmonary embolism. There has been a

60% decrease in the platelet count and no clinical change. Which of the following is indicated? -

ANSWER✔✔-Discontinue heparin and being argatroban.

The patient most likely has HIT. Exposure to heparin needs to discontinued and a direct thrombin

inhibitor started for continued anticoagulation.


The patient with oat cell carcinoma has the following clinical findings: low urine output, low serum

osmolality, hyponatremia, and elevated urine sodium. The nurse anticipates which of the following as

part of the treatment plan? - ANSWER✔✔-Phenytoin (Dilantin), 3% saline.




The patient has signs of SIADH which results in production of excessive ADH. Dilantin will inhibit ADH

secretion and 3% saline will increase serum sodium.


Peep therapy and mechanical ventilation are ordered for the patient with acute respiratory failure.

Which of the following is a possible complication? - ANSWER✔✔-Barotrauma




The addition of positive end-expiratory pressure will increase alveolar recruitment, prevent atelectasis

and improve oxygenation. However, the increase in intrathoracic pressure may lead to pneumothorax or

subcutaneous emphysema.


The postoperative thoracic surgery patient has bubbling in the water seal drainage chamber of the chest

tube. Which of the following interventions is indicated? - ANSWER✔✔-avoid high airway pressures




Bubbling in the water seal chamber is due to a pleural air leak, and high airway pressure will either

prevent resolution of the current air leak or make it worse.

Which clinical sign might patients with both systolic and diastolic heart failure have in common? -

ANSWER✔✔-Lung crackles




Both a problem with systolic (ejection problem) and diastolic (filling problem) will increase left heart

pressure and cause cardiogenic pulmonary edema (lung crackles).


Which of the following is most likely to result in a low Sv02?




A. Hypotermia


B. Fever


C. Severe sepsis - ANSWER✔✔-Fever




Fever increases metabolic rate and consumption, which may lead to a drop in mixed venous oxygen

saturation.


The nurse needs to assess adequacy of the tubing/catheter system for the arterial line. Which of the

following interventions will best assess this? - ANSWER✔✔-Perform a square wave test


The patient requires fluid resuscitation and 8 units of PRBC's status post traumatic injury. Which of the

following interventions is most appropriate? - ANSWER✔✔-Warm blood products and crystalloids




Warming fluids and blood needed for traumatic injury will prevent hypothermia and its related adverse

effects.
