HESI 799 RN Exit Exam
1. Following a gunshot wound to the abdomen, a young adult male had an emergency bowel resection and received multiple blood products while in the operating room. His current blood pressure is 78/52 mm Hg, he is being mechanically ventilated, and his oxygen saturation is 87%. His laboratory values include hemoglobin 7.0 g/dL, platelets 20,000/mm³, and white blood cells 1,500/mm³. Based on these assessment findings, which intervention should the nurse implement first?
- A. Transfuse packed red blood cells.
- B. Obtain blood and sputum cultures.
- C. Infuse 1000 ml of normal saline.
- D. Titrate oxygen to keep O2 saturation at 90%.
Correct answer: A
Rationale: The client is exhibiting signs of severe anemia and hypovolemic shock, indicated by low hemoglobin levels and hypotension. The first priority is to address the low hemoglobin by transfusing packed red blood cells to improve oxygen-carrying capacity and perfusion to vital organs. While obtaining blood and sputum cultures is important for identifying potential infections, infusing normal saline can help with volume expansion but does not address the primary issue of severe anemia. Titrating oxygen to maintain an oxygen saturation of 90% is crucial but should follow the administration of packed red blood cells to optimize oxygen delivery.
2. The nurse provides feeding tube instructions to the wife of a client with end-stage cancer. The client's wife performs a return demonstration correctly but begins crying and tells the nurse, 'I just don't think I can do this every day.' The nurse should direct further teaching strategies toward which learning domain?
- A. Cognitive.
- B. Affective.
- C. Comprehension.
- D. Psychomotor.
Correct answer: B
Rationale: The correct answer is B: Affective. The affective domain involves feelings and emotions, which are significant factors in the wife’s ability to cope and perform the required care. In this scenario, the wife's emotional response indicates a need for further support and teaching strategies to address her emotional concerns and build her confidence. Choices A, C, and D are incorrect because the issue at hand is not purely cognitive (knowledge), comprehension (understanding), or psychomotor (physical skills), but rather an emotional response that falls under the affective domain.
3. The nurse is caring for a client with diabetic ketoacidosis (DKA). Which laboratory value requires immediate intervention?
- A. Serum glucose of 300 mg/dL
- B. Serum potassium of 4.5 mEq/L
- C. Serum bicarbonate of 15 mEq/L
- D. Serum pH of 7.28
Correct answer: D
Rationale: A serum pH of 7.28 indicates metabolic acidosis in a client with diabetic ketoacidosis (DKA), requiring immediate intervention. In DKA, the body produces excess ketones, leading to acidosis. Monitoring and correcting the pH level is crucial in managing DKA. Serum glucose levels may be high in DKA, but the immediate concern is correcting the acidosis to prevent complications. Serum potassium and bicarbonate levels are also important but not as immediately critical as correcting the acidosis in DKA.
4. The nurse notes that a client who has undergone a thoracotomy has an increase in a large amount of dark red blood in the chest tube collection chamber. What action should the nurse take?
- A. Document the findings for this procedure as expected
- B. Notify the healthcare provider immediately
- C. Check the tube for kinks or dependent loops
- D. Increase the suction to the chest drainage system
Correct answer: B
Rationale: An increase in a large amount of dark red blood in the chest tube collection chamber may indicate active bleeding. The nurse should notify the healthcare provider immediately to address the situation promptly and prevent further complications. Documenting the findings without taking immediate action could delay necessary interventions. Checking the tube for kinks or dependent loops is a good practice but not the priority when dealing with a potentially life-threatening situation like active bleeding. Increasing the suction without healthcare provider's orders can lead to complications and is not appropriate in this scenario.
5. The nurse discovers that an elderly client with no history of cardiac or renal disease has an elevated serum magnesium level. To further investigate the cause of this electrolyte imbalance, what information is most important for the nurse to obtain from the client's medical history?
- A. Frequency of laxative use for chronic constipation
- B. Dietary intake of magnesium-rich foods
- C. Use of magnesium-containing supplements
- D. History of alcohol use
Correct answer: A
Rationale: The correct answer is A. Frequent use of magnesium-containing laxatives can lead to hypermagnesemia, particularly in elderly clients. Option B, dietary intake of magnesium-rich foods, may contribute to elevated serum magnesium levels but is less likely the cause in this scenario. Option C, the use of magnesium-containing supplements, can also contribute to hypermagnesemia but is not as common in elderly clients without a history of using such supplements. Option D, history of alcohol use, is less relevant to the development of elevated serum magnesium levels compared to laxative use for chronic constipation.
