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/mmÂ³, and white blood cells 1,500/mmÂ³. 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. A client with chronic obstructive pulmonary disease (COPD) is admitted with an exacerbation. Which laboratory value is most concerning?

A. Serum potassium of 6.5 mEq/L
B. Serum bicarbonate of 18 mEq/L
C. Serum glucose of 350 mg/dl
D. Serum sodium of 135 mEq/L

Correct answer: A

Rationale: A serum potassium level of 6.5 mEq/L is concerning in a client with COPD exacerbation as it may lead to life-threatening arrhythmias, requiring immediate intervention. Hyperkalemia can cause cardiac arrhythmias, which pose a significant risk to the patient's life. Options B, C, and D are not typically associated with immediate life-threatening risks in the context of a COPD exacerbation.

3. A client with type 1 diabetes is admitted with diabetic ketoacidosis (DKA). Which intervention should the nurse implement first?

A. Administer intravenous insulin as prescribed.
B. Monitor the client's urine output.
C. Administer intravenous fluids.
D. Administer 50% dextrose IV push.

Correct answer: A

Rationale: Administering intravenous insulin is the initial priority in managing diabetic ketoacidosis (DKA). Insulin helps to reduce blood glucose levels and correct metabolic acidosis, addressing the underlying cause of DKA. Monitoring urine output (choice B) is important but is not the first intervention needed. Administering intravenous fluids (choice C) is essential to correct dehydration in DKA, but insulin therapy takes precedence. Administering 50% dextrose IV push (choice D) is contraindicated in DKA as it can exacerbate hyperglycemia.

4. After receiving lactulose, a client with hepatic encephalopathy has several loose stools. What action should the nurse implement?

A. Send stool specimen to the lab
B. Measure abdominal girth
C. Encourage increased fiber in the diet
D. Monitor mental status

Correct answer: D

Rationale: The correct action for the nurse to implement after a client with hepatic encephalopathy has loose stools following lactulose administration is to monitor the client's mental status. Lactulose is given to lower serum ammonia levels in hepatic encephalopathy, and loose stools can be an expected side effect of its use. Monitoring mental status is crucial because changes in mental status, such as confusion or altered level of consciousness, are key indicators of hepatic encephalopathy worsening. Sending a stool specimen to the lab would not be the priority in this situation as loose stools are a known effect of lactulose. Measuring abdominal girth is more relevant for conditions like ascites, not loose stools. Encouraging increased fiber in the diet may be beneficial for constipation but is not the immediate action needed when loose stools occur after lactulose administration.

5. A client who had a gestational trophoblastic disease (GTD) evacuated 2 days ago is being monitored for choriocarcinoma. She lives in a rural area, and her husband takes the family car to work daily, leaving her without transportation during the day. What intervention is most important for the nurse to implement?

A. Teach the client about the use of a home pregnancy test.
B. Schedule a weekly home visit to draw hCG values.
C. Make a 5-week follow-up appointment with the healthcare provider.
D. Begin chemotherapy administration during the first home visit.

Correct answer: B

Rationale: Scheduling weekly home visits to monitor hCG levels is critical for early detection of choriocarcinoma, a potential complication of GTD. Choice A is incorrect because a home pregnancy test is not the appropriate method to monitor for choriocarcinoma. Choice C is less frequent than necessary for close monitoring. Choice D is incorrect as chemotherapy administration should be based on confirmed diagnosis and treatment plan, not initiated during the first home visit.
