SOLVED

 Question 11 The nurse is planning essential activities for a critically ill patient. In order to provide the least impact on oxygen consumption, the nurse would be certain the patient rests before and after which activity? 1. Abdominal wound dressing change 2. Bed bath 3. Daily weight using bed sling scale 4. Turning and repositioning Question 12 A patient’s PaO2 level is 48 mm Hg. The nurse would plan care to prevent development of which condition? 1. Hypoxemia 2. Intrapulmonary shunt 3. Hypoxia 4. Hyperventilation Question 13 A patient is going to be assessed for oxygen consumption level. Which parameter will the nurse identify for this assessment? 1. Serum potassium level 2. Hemoglobin level 3. Creatinine level 4. Serum lactate level Question 14 A patient’s mixed venous oxygen saturation level is 56%. What evaluation would the nurse make of this reading? 1. The cells are taking more oxygen to meet needs. 2. The cells are not receiving enough oxygen. 3. The cells are releasing more carbon dioxide. 4. There isn’t enough oxyhemoglobin to meet the patient’s needs. Question 15 A patient with COPD says, “I have to rest a lot. It just wears me out trying to breath.” The nurse interprets this statement to mean the patient has difficulty with which respiratory process? 1. Perfusion 2. Diffusion 3. Ventilation 4. Consumption Question 16 A patient injured in an explosion has a flail chest and crushing injuries to his left arm and leg. He is unconscious and is losing blood rapidly. Laboratory testing reveals impaired oxygenation. Nursing interventions should be implemented to improve which components of oxygenation disrupted by this injury? 1. Ventilation 2. Thickness of the alveolar–capillary membrane 3. Oxygen affinity 4. Hemoglobin concentration 5. Blood flow to the lungs Question 17 A nurse is preparing a patient for pulmonary functioning testing (PFT). Which nursing statements will help to reinforce teaching about the purposes of these tests? 1. These tests can help in the diagnosis of any pulmonary diseases you may have. 2. We can monitor how well therapies are working by comparing the results of your tests. 3. Insurance companies require these tests be done before you can be discharged from the hospital. 4. By testing you frequently we can identify changes occurring in your pulmonary health before they become severe. 5. The tests give us numbers so we can make accurate assessments of your pulmonary health. Question 18 A patient who is receiving chemotherapy is anemic and has low CaO2 levels. Which nursing interventions offer the best support for this patient? 1. Monitor the administration of blood products. 2. Administer diuretics as ordered. 3. Keep the patient’s oxygen cannula in place. 4. Keep the patient on bedrest 5. Monitor the patient’s pulmonary artery wedge pressure (PAWP). Question 19 Arterial blood gases were drawn when a patient was discovered in cardiopulmonary arrest. Which results would the nurse evaluate as indicating global lactic acidosis? 1. pH 7.21 2. HCO3 24 mEq/L 3. Base excess –12 mmol/L 4. PaO2 82 mm Hg 5. PaCO2 37 mmHg Question 20 A nurse is monitoring trends of a patient’s SvO2 as a measure of oxygen delivery to tissues. The nurse would be concerned about the accuracy of this trending if which patient condition develops? 1. The patient’s heart rate drops. 2. The patient develops a high fever. 3. The patient develops gastrointestinal bleeding. 4. The patient’s SaO2 improves with antibiotic therapy. 5. The patient is receiving multivitamins in intravenous infusions.
