Introduction to Human Nutrition

Managed care refers to a system in health care delivery that structures the use, cost, quality, and effectiveness of health services and includes pre-authorization, diagnostic related groups (DRGs), critical paths (A), case management care plans, and variance analysis. Primary nursing is a nursing care model that ensures autonomy, authority, and accountability in providing the total nursing process for the client during a period of hospitalization (B). Case management (C) is under the umbrella of managed care as a cost-containment strategy and a nursing care delivery model that coordinates standardized patterns of care and length of hospitalization. Managed care relies on the healthcare provider (D) as the gatekeeper to minimize unnecessary utilization. Awarded 1.0 points out of 1.0 possible points. 7. 8.ID: 310947650 A nurse who is working the 11 p.m. to 7 a.m. shift enters a client's room when the pulse oximeter alarms and reads 82%. The client appears to be sleeping. Which action should the nurse take first? o Gently apply oxygen without waking the client. o Record the reading and monitor for further decrease. o Reposition the pulse oximeter until it stops alarming. o Rouse the client and obtain vital signs. Correct It is most important for the nurse to assess the client's respiratory status (D), even if the client must be awakened to do so. (A) is not safe. (B) constitutes unsafe practice because the nurse has essentially ignored the data provided by the pulse oximeter. Repositioning the pulse oximeter might be indicated if the vital sign findings are within normal limits and the client is not exhibiting signs of respiratory distress, but more data needs to be obtained prior to implementing (C). Awarded 1.0 points out of 1.0 possible points. 8. 9.ID: 310950756 On the second postoperative day, a client is pulseless, apneic, and unresponsive. In what order should the nurse implement these nursing actions? (Arrange from first on top to last on the bottom.) Correct 1. Call for assistance. 2. Initiate chest compressions. 3. Ventilate the client. 4. Delegate emergency responsibilities. Based on the recommendations of the American Heart Association, high quality chest compressions should be the first action in cardiopulmonary resuscitation (CPR). The sequence is compressions, airway, and breathing (CAB). Delegating emergency responsibilities is last. Awarded 1.0 points out of 1.0 possible points. 9. 10.ID: 311018727 The primary nurse receives the 0700 shift report for 4 clients on a medical unit. When prioritizing care, which action should the nurse implement first? o Administer insulin per sliding scale to a client with a capillary glucose of 285. Correct o Assess the lung sounds of a client with pneumonia who is ready to go home. o Flush the lumen of a client's triple lumen central venous catheter with saline. o Review the potassium levels of a client who receives a daily loop diuretic. The nurse should first administer the insulin per scaling scale (A) to the client with hyperglycemia to prevent further elevation of the serum glucose levels. (B and C) are of less immediacy and can be delayed until the higher priority interventions are completed. The client's potassium level should be checked before administering a loop diuretic (D), but this can be done after administering the sliding scale insulin. Awarded 1.0 points out of 1.0 possible points. 10. 11.ID: 310953473 The nurse is planning a diabetes education course for a group of clients newly diagnosed with diabetes mellitus. Which collaborative approach is the best use of interdisciplinary team members? o Schedule the pharmacist to teach about treatment of hypoglycemia.
