HESI 799 RN Exit Exam
1. A client with a head injury is receiving mechanical ventilation. Which finding indicates to the nurse that the client may be experiencing increased intracranial pressure (ICP)?
- A. Widening pulse pressure
- B. Sudden drop in heart rate
- C. A decrease in urine output
- D. Elevated blood pressure and widening pulse pressure
Correct answer: D
Rationale: In a client with increased intracranial pressure (ICP), the body's compensatory mechanisms lead to an elevation in blood pressure and a widening pulse pressure. This occurs due to the body's attempt to maintain cerebral perfusion. Therefore, elevated blood pressure and widening pulse pressure are classic signs of increased ICP and necessitate immediate attention. Choices A, B, and C are incorrect because a widening pulse pressure, sudden drop in heart rate, or decreased urine output are not specific indicators of increased ICP.
2. A male client is admitted with a bowel obstruction and intractable vomiting for the last several hours despite the use of antiemetics. Which intervention should the nurse implement first?
- A. Infuse 0.9% sodium chloride 500 ml bolus
- B. Administer an antiemetic intravenously
- C. Insert a nasogastric tube
- D. Prepare the client for surgery
Correct answer: A
Rationale: The correct first intervention for a male client with a bowel obstruction and intractable vomiting is to infuse 0.9% sodium chloride 500 ml bolus. This intervention is crucial to address the risk of hypovolemia due to excessive vomiting. Administering intravenous fluids will help prevent dehydration, maintain blood pressure, and stabilize the client's condition. Choice B, administering an antiemetic intravenously, may not be effective as the client has already been unresponsive to antiemetics orally. Choice C, inserting a nasogastric tube, may be necessary but is not the priority in this situation. Choice D, preparing the client for surgery, should only be considered after stabilizing the client's fluid and electrolyte balance.
3. A client with a history of diabetes mellitus is admitted with a blood glucose level of 600 mg/dl and is unresponsive. Which intervention should the nurse implement first?
- A. Administer 50% dextrose IV push.
- B. Administer insulin as prescribed.
- C. Monitor the client's urine output.
- D. Obtain a blood glucose level.
Correct answer: A
Rationale: Administering 50% dextrose IV push is the first priority in treating a blood glucose level of 600 mg/dl in a client who is unresponsive due to hyperglycemia. This intervention is crucial to rapidly raise the client's blood glucose levels and address the emergency situation. Administering insulin (Choice B) would further lower the blood glucose level, worsening the client's condition. Monitoring urine output (Choice C) and obtaining a blood glucose level (Choice D) are important assessments but are secondary to the immediate need to address the high blood glucose levels causing the client's unresponsiveness.
4. A client with type 1 diabetes is admitted with diabetic ketoacidosis (DKA). Which clinical finding is most concerning?
- A. Serum glucose of 500 mg/dL
- B. Serum glucose of 600 mg/dL
- C. Serum potassium of 5.5 mEq/L
- D. Serum bicarbonate of 18 mEq/L
Correct answer: D
Rationale: A serum bicarbonate level of 18 mEq/L is most concerning in a client with DKA as it indicates metabolic acidosis, requiring immediate intervention. In DKA, the body produces excess ketones, leading to metabolic acidosis. A low serum bicarbonate level is a key indicator of this acid-base imbalance. Elevated serum glucose levels are expected in DKA but are managed through insulin therapy. Serum potassium levels can fluctuate in DKA due to insulin deficiency, but a value of 5.5 mEq/L is not as immediately concerning as metabolic acidosis. Therefore, the most critical finding in this scenario is the low serum bicarbonate level.
5. The mother of an adolescent tells the clinic nurse, 'My son has athlete's foot. I have been applying triple antibiotic ointment for two days, but there has been no improvement.' What instruction should the nurse provide?
- A. Antibiotics take two weeks to become effective against fungal infections like athlete's foot.
- B. Continue using the ointment for a full week, even after the symptoms disappear.
- C. Applying too much ointment can reduce its effectiveness. Apply a thin layer to prevent maceration.
- D. Stop using the ointment and encourage complete drying of the feet and wearing clean socks.
Correct answer: D
Rationale: The correct answer is D. Athlete's foot (tinea pedis) is a fungal infection, not a bacterial infection that would respond to antibiotics. The primary management involves keeping the feet well-ventilated, dry after bathing, and wearing clean socks to prevent moisture buildup, which promotes fungal growth. Using an antibiotic ointment like triple antibiotic ointment is not effective for treating athlete's foot. Therefore, the nurse should advise the mother to stop using the antibiotic ointment and focus on promoting proper foot hygiene to manage the fungal infection. Choices A, B, and C are incorrect as they do not address the fungal nature of athlete's foot and the ineffectiveness of antibiotic ointments in its treatment.
