Barrons CCRN Test 1 2025 Questions
and Answers
Which of the following clinical signs will the patient with a cerebellar abnormality
most likely demonstrate? - ANSWER-Cerebellum is responsible for balance and
equillibrium
Cardiogenic shock secondary to left ventricular failure will generally result in: -
ANSWER-Widening Pule Pressure
The systolic pressure decreases due to a drop in cardiac output; however, the
diastolic pressure either stays the same or increases due to a compensatory increase
of the systemic vascular resistance. The remaining choices are not found in
cardiogenic shock.
The patient was admitted with acute inferior wall STEMI; the physician advises the
nurse to monitor the patient for signs of right ventricular (RV) infarction. Which
of the following are signs of RV infarction? - ANSWER-Distended neck veins,
clear lungs

,If the RV contractility decreases, pressure proximal to the right ventricle (which is
the right atrium) increases, resulting in distended neck veins. As the right heart
fails, left heart preload decreases, lung sounds clear.
Which of the following is correct in relation to a shift of the oxyhemoglobin
dissociation curve to the right? - ANSWER-May be due to hyperthermia
Fever will shift the oxyhemoglobin dissociation curve to the right, more readily
releasing oxygen from hemoglobin; this will decrease the SaO2. The remaining
choices will shift the oxyhemoglobin dissociation curve to the left.
The most common cause of acute liver failure is - ANSWER-Salycilate overdose
Salicylate overdose results in renal failure and biliary obstruction may lead to
pancreatitis or gallbladder disease.
Alcohol abuse results in - ANSWER-Chronic renal failure
Which of the following is indicative of a mixed acid-base disorder? - ANSWER-ph

, PacO2 29
Pao2 72
Hco3 15
The decrease in PaCO2 is evidence of respiratory alkalosis and the decreased
HCO3 is evidence of a metabolic acidosis. The patient with severe sepsis or septic
shock may present with this type of mixed acid-base disorder.
The patient with a temporary transvenous pacemaker develops pacemaker
malfunction. The orientee is instructed to reposition the patient to try to correct
the problem. The cardiac monitor most likely demonstrates: - ANSWER-Pacer
spikes without a QRS
Failure to capture (spikes present without QRS) may be corrected by repositioning
the patient to the side.
The 75-year-old patient develops frequent 6 to 10 second episodes of asystole,
interspersed with normal sinus rhythm that is associated with hypotension. The
priority intervention is: - ANSWER-Transcutaneous pacing
