Perioperative Care Questions Quizlet Questions
Question 1 of 5
A postoperative client has respiratory depression after receiving midazolam (Versed) for sedation. Which action by the nurse is most appropriate?
Correct Answer: A
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 2 of 5
The nurse at a long-term care facility is assessing each of the residents. Which resident most likely faces the greatest risk for aspiration?
Correct Answer: A
Rationale: Aspiration risk is highest in patients with impaired swallowing or protective airway reflexes, such as the gag, laryngeal, and cough reflexes, which are frequently disrupted by a severe stroke. Stroke-related dysphagia stems from neurological damage to cranial nerves (e.g., IX, X), leading to uncoordinated swallowing and silent aspiration, especially within weeks of the event when recovery is incomplete. Mid-stage Alzheimer's typically affects cognition more than motor swallowing function, with dysphagia emerging later. A 92-year-old needing ADL help may have frailty but not necessarily swallowing impairment unless tied to a specific condition. Severe rheumatoid arthritis causes joint deformity, not typically dysphagia, unless secondary issues (e.g., cervical spine involvement) affect swallowing, which isn't indicated. The stroke patient's recent neurological insult makes them most vulnerable, requiring the nurse to prioritize swallowing assessments and interventions like modified diets or speech therapy.
Question 3 of 5
A patient is receiving thrombolytic therapy for the treatment of pulmonary emboli. What is the best way for the nurse to assess the patients oxygenation status at the bedside?
Correct Answer: B
Rationale: Monitoring pulse oximetry is the best bedside method to assess oxygenation status during thrombolytic therapy for pulmonary embolism (PE), providing real-time, noninvasive measurement of oxygen saturation (SpO2). It reflects how effectively oxygen reaches the blood despite PE-induced ventilation-perfusion mismatch, guiding adjustments in oxygen therapy (e.g., aiming for SpO2 >90%). Serial arterial blood gases (ABGs) are precise but invasive, time-consuming, and not practical for continuous bedside use. Pulmonary function tests assess airway obstruction or restriction, not acute oxygenation, and are irrelevant here. Incentive spirometry measures inspiratory effort, aiding atelectasis prevention, not oxygenation. Pulse oximetry's immediacy and simplicity enable the nurse to detect hypoxemia promptly, ensuring timely intervention (e.g., increasing FiO2) as thrombolytics dissolve the clot, critical in this dynamic, high-risk scenario.
Question 4 of 5
A nurse is assessing a patient whose respiratory disease in characterized by chronic hyperinflation of the lungs. What would the nurse most likely assess in this patient?
Correct Answer: C
Rationale: Chronic hyperinflation, typical in COPD with emphysema, results from air trapping due to alveolar destruction and loss of elastic recoil, reshaping the thorax into a barrel chest expanded anteroposterior diameter from flattened diaphragm and elevated ribs. The nurse assesses this physical sign via inspection, noting a rounded chest contour, reflecting advanced disease. Oxygen toxicity occurs with prolonged high O2 therapy, not hyperinflation itself. Chronic chest pain isn't a COPD feature unless from comorbidities (e.g., pleurisy), as emphysema involves dyspnea over pain. Long, thin fingers (arachnodactyly) relate to Marfan syndrome, not lung disease. Barrel chest's presence informs the nurse of disease severity, guiding interventions like breathing techniques or oxygen titration to manage chronic respiratory compromise.
Question 5 of 5
A patient is having pulmonary-function studies performed. The patient performs a spirometry test, revealing an FEV1/FVC ratio of 60%. How should the nurse interpret this assessment finding?
Correct Answer: D
Rationale: An FEV1/FVC ratio of 60% below the normal threshold of 70% indicates obstructive lung disease on spirometry, reflecting reduced airflow from narrowed airways, as in COPD or asthma. FEV1 (forced expiratory volume in 1 second) measures air expelled quickly, while FVC (forced vital capacity) is total air exhaled; a low ratio shows expiration is disproportionately impaired, typical of obstruction. Strong exercise tolerance contradicts this, requiring unimpeded airflow. Exhalation volume isn't ‘normal' the ratio signals restriction in speed, not capacity alone. Respiratory infection may worsen obstruction but isn't diagnosed by spirometry alone. The nurse's interpretation guides further assessment (e.g., bronchodilator response) and management (e.g., inhalers), aligning with pulmonary function standards for diagnosing obstructive pathology.
