HESI MEDICAL SURG PROCTORED AXAM

1. A nurse is following the Ventilator Bundle standards to prevent ventilator-associated pneumonia. Which strategies is the nurse using? (Select all that apply.) a. Head of bed elevation to 90 degrees at all times b. Daily oral care with chlorhexidine c. Cuff monitoring for adequate seal d. Clean technique when suctioning e. Daily “sedation vacations” f. Heart failure prophylaxis ANS: B, C, E The key components of the Institute for Healthcare Improvement (IHI) Ventilator Bundle are: Elevation of the head of the bed (HOB)—elevation is 30 to 45 degrees Daily “sedation vacations” and assessment of readiness to extubate Peptic ulcer disease prophylaxis Deep venous thrombosis prophylaxis Daily oral care with chlorhexidine Monitor cuff pressure frequently to ensure that there is an adequate seal to prevent aspiration of secretions is also included. Sterile technique is used for suctioning when on ventilators. Heart failure prophylaxis is not a component. 2. A nurse is teaching a community health promotion class and discusses the flu vaccine. Which information will the nurse include in the teaching session? (Select all that apply.) a. It is given yearly. 1 HESI MEDICAL SURG PROCTORED AXAM b. It is given in a series of four doses. c. It is safe for children allergic to eggs. d. It is safe for adults with acute febrile illnesses. e. The nasal spray is given to people over 50. f. The inactivated flu vaccine is given to people over 50. ANS: A, F Annual (yearly) flu vaccines are recommended for all people 6 months and older. The inactivated flu vaccine should be given to these individuals with chronic health problems and those 50 and older. People with a known hypersensitivity to eggs or other components of the vaccine should consult their health care provider before being vaccinated. There is a flu vaccine made without egg proteins that is approved for adults 18 years of age and older. Adults with an acute febrile illness should schedule the vaccination after they have recovered. The live, attenuated nasal spray vaccine is given to people from 2 through 49 years of age if they are not pregnant or do not have certain long-term health problems such as asthma; heart, lung, or kidney disease; diabetes; or anemia. 3. A nurse is caring for a patient with sleep apnea. Which types of ventilator support should the nurse be prepared to administer for this patient? (Select all that apply.) a. Assist-control (AC) b. Pressure support ventilation (PSV) c. Bilevel positive airway pressure (BiPAP) d. Continuous positive airway pressure (CPAP) 2 e. Synchronized intermittent mandatory ventilation (SIMV) ANS: C, D Ventilatory support is achieved using a variety of modes, including continuous positive airway pressure (CPAP) and bilevel positive airway pressure (BiPAP). The purpose of CPAP and BiPAP is to maintain a positive airway pressure and improve alveolar ventilation. This prevents or treats atelectasis by inflating the alveoli, reducing pulmonary edema by forcing fluid out of the lungs back into circulation, and improving oxygenation in those with sleep apnea. AC, PSV, and SIMV are invasive mechanical ventilation and are not routinely used on patients with sleep apnea. AC delivers a set tidal volume (VT) with each breath, regardless of whether the breath was triggered by the patient or the ventilator. Synchronized intermittent mandatory ventilation like AC delivers a minimum number of fully assisted breaths per minute that are synchronized with the patient’s respiratory effort. Any breaths taken between volume-cycled breaths are not assisted; the volume of these breaths is determined by the patient’s strength, effort, and lung mechanics. PSV mode is often combined with SIMV mode: inspiratory pressure is added to spontaneous breaths to overcome the resistance of the endotracheal tube or to help increase the volume of the patient’s spontaneous breaths.
