CCRN QUESTIONS and Answers (LatestUpdate 2024) 190 Questions
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: - Correct 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? - Correct 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 - Correct 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 - Correct 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? - Correct 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: - Correct 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? - Correct 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? - Correct 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? - Correct 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.
