PCCN questions with complete solutions graded A+ 2023/2024

PCCN questions Two days following a near-drowning accident, a pt is dyspneic, using accessory muscles, expectorating large amounts of secretions and reporting feeling of impending death. Changes to the assessment data include RR- 24 TO 36 CXR clear to bilateral diffuse infiltrates ABG 40% face mask or 100% non-rebreather mask pO2 120 mm Hg to 56 mm Hg pCO2 33 mmHg to 56 mmHg pH 7.42 to 7.35 HCO3 24 meq/L to 27 mEq/L Which of the ff do these changes most likely represent A. aspiration pneumonia B. pulmonary embolism C. interstitial pneumonitis D. ARDS - correct answer D. The onset of symptoms occured within 48 hours of the incident. THe bilateral diffuse infiltrates and ABG results indicating hypoxemia and CO2 retention are all consistent with ARDS. Aspiration pneumonia should include hypoxxemia, respiratory alkalosis. The CXR results would reveal an area of opacity with aspiration pneumonia rather than diffuse infiltrates. Interstitial lung disease invlolves an inflammation of supportive tissue between the air sacs rather than inflammation in the air sacs themselves. Symptoms would be SOB and a dry cough. A pt reports chest pain that is sharp, constant, worse when lying down and alleviated with sitting up and leaning forward. The most likely cause of these findings is A. ACS B. pericarditis C. PE D. AAA - correct answer B Pericarditis is inflammation of the pericardial sac. The damaged epicardium becomes rough and inflamed and irritates the pericardium lying adjacent to it, precipitating pericarditis. Pain is the most common symptom of pericarditis. THe pain is sharp, constant and is alleviated when sitting up and leaning forward. A pt tells a nurse, "I don't know how I'm going to pay for this hospitalization." The nurse should A. arrange a meeting with hospital social services staff B. Notify the business office so a payment plan can be designed C. redirect the pt toward meeting psychologic needs D. give the pt applications for public assistance medical coverage - correct answer A. Collaboration with a social worker is indicated in this case the social worker can assist the pt in identifying ways to address the financial implications of this hospitalization and help identify methods of payments. A cardiac pt with with DNR status is being managed medically. The nurse notes a new cough, thick yellow sputum and a temperature of 101.4 (38.4) Coarse crackles are present in the right upper field. The nurse should most immediately anticipate A. blood and sputum cultures followed by a broad spectrum abx B. mucolytics and judicious IV fluid administration C. an antyipyretic and conservative management D. NPO status and encouragement of frequent activity - correct answer A. This pt symptoms are consistent with pneumonia. Management should include abx therapy, oxygen therapy for hypoxemia, mechanical ventilation if acute respiratory failure develops, fluid management for hydration, nutritional support, and treatment of associated medical problems and complications. Which of the ff findings is most indicative of a ruptured aortic aneurysm A. Back pain B. bounding peripheral pulses C. intermittent claudication D. warm, flushed skin - correct answer A. An aneurysm is the localized dilation of an artery. Should an aneurysm rupture, blood will build up under pressure in the tissues surrounding the aorta, which can result in acute pain and tenderness in theses areas. This is particularly the case if the aneurysm leaks from the back of the aorta. Ruptured AAA presents with a classic triad of pain in the flank or back, hypotension and a pulsatile abdominal mass; however, only about half of the full triad. The pt will
