PCCN STUDY QUESTIONS(LATEST PRACTICE
QUESTIONS AND ANSWERS 2022/2023
OVERVIEW)
What are the 3 most common risk factors for an MDRO infection? (correct answers)impaired immune
function, recent surgery, or indwelling cathethers/tubes
Pt with pericarditis, receiving coumadin, is at risk for what? (correct answers)Cardiac tamponade. Classic
signs include hypotension, narrowing pulse pressure, thready pulse, and tachypenea
Signs include hypotension, narrowing pulse pressure, thready pulse, and tachypenea (correct
answers)Cardiac tamponade
Why would a post- CABG patient receive an insulin drip? (correct answers)To reduce the risk of
infection; postoperative glucose control has been shown to decrease the risk of infection in these
patients
How does AKI cause acidosis? (correct answers)Decreased urine output impairs potassium excretion.
The resulting hyperkalemia causes a shift in H+, the accumulation results in acidosis
A patient with severe abdominal pain for the last week presents with elevated amylase, lipase, and a
rigid abdomen. What do you suspect? (correct answers)pancreatitis
How is acute pancreatitis treated? (correct answers)hydration, electrolyte balance, nutrition and pain
control
What procedure measures heart pressure and diagnoses pulmonary hypertension? (correct
answers)right-sided heart catheterization; provides measurements of right atrium, right ventricle,
pulmonary artery, and pulmonary artery occlusive pressure
Why does lowering fever improve prognosis in stroke pts? (correct answers)Increased metabolic
demands, enhanced neurotransmitter release, and increased free radicals may increase stroke
mortality.
What is a contraindication to administer nitroglycerin to a pt with a right ventricular infarction? (correct
answers)nitroglycerin reduces preload, and pts with a RVI are preload dependent
What are six risk factors for delirium? (correct answers)cognitive impairment, sleep deprivation,
dehydration, immobility, hearing impairment, vision impairment
What does a pericardial friction rub sound like? (correct answers)grating sound with s1 and s2
