PCCN Exam Study 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 i nfiltrates 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. in terstitial pneumonitis D. ARDS - ✔✔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 inflamm ation 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. perica rditis C. PE D. AAA - ✔✔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 - ✔✔A. Collaboration with a social worker is indicated in this case the s ocial 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 - ✔✔A. This pt symptoms are consistent with pneumonia. Management should include abx therapy, oxygen therapy for hypoxemia, mechanical ventilation if acute r espiratory 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 - ✔✔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 te nderness 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 complain of the pain and may feel cold, sweaty and faint on standing. The pt may also report abdominal pain. A small percentage may have vomiting According to recommendations based on research findings, pain assessment should occur A. based on changes in vital signs B. only when the pt movements indicate the pt is seeking attention C. routinely, regardless of physical findings D. only when the presence of pain can be validated - ✔✔C. Pain is considered the fifth vital sign and must b e assessed regularly. Presence of physical findings may be part of the comprehensive assessment of pain. However, physical findings may not be present in all patients with pain A pt with a tracheostomy requires frequent suctioning for thick sputum, A nurs e finds a colleague instilling saline in the endotracheal tube prior to suctioning. The most appropriate response by the nurse would be to A. report the colleague to the charge nurse or manager B. noted the practice on the pt chart to ensure consistency of suctioning techniques C. ask the attending physician to review the suctioning policy. D. collaborate with the colleague to review the evidence about this practice. - ✔✔D. In addition to an unappreciable increase in sputum recovery, use of NS adversely aff ects arterial and global tissue oxygenation and dislodges bacterial colonies, thus contributing to lower airway contamination. Other harmful pt outcomes have been reported in the nursing literature, including delays in return to baseline vital signs, Spo2 and intracranial pressure. Because no solid scientifically based benefits for routine use of normal saline have been shown, it is highly recommended that this potentially harmful practice be abandoned. Instead, treatment considerations should center on way s to prevent the development of thick tenacious secretions. A
