HESI 799 RN Exit Exam
1. A client with type 1 diabetes is admitted with hypoglycemia. Which intervention should the nurse implement first?
- A. Administer 50% dextrose IV push
- B. Administer 15 grams of oral glucose
- C. Recheck the blood glucose level in 15 minutes
- D. Administer a glucagon injection
Correct answer: A
Rationale: Administering 50% dextrose IV push is the first priority in treating hypoglycemia to rapidly increase blood glucose levels. This choice is correct because in severe cases of hypoglycemia, when a client is admitted and unconscious or unable to swallow, intravenous administration of dextrose is crucial to quickly raise blood glucose levels. Option B, administering 15 grams of oral glucose, would be suitable for conscious clients with mild hypoglycemia who can swallow safely. Option C, rechecking blood glucose levels, should follow after immediate intervention to assess the response. Option D, administering a glucagon injection, is more suitable for cases where dextrose is not readily available or when the client does not respond to dextrose administration.
2. 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.
3. The nurse is caring for a client with acute kidney injury (AKI) secondary to gentamicin therapy. The client's serum blood potassium is elevated. Which finding requires immediate action by the nurse?
- A. Anuria for the last 12 hours.
- B. Tachycardia and hypotension.
- C. Decreased urine output.
- D. Elevated blood urea nitrogen (BUN) levels.
Correct answer: A
Rationale: The correct answer is A. Anuria for the last 12 hours. Anuria, the absence of urine output, indicates complete kidney failure and is a medical emergency that requires immediate attention. In acute kidney injury (AKI), the kidneys are unable to filter waste from the blood effectively, leading to a buildup of toxins and electrolyte imbalances like elevated blood potassium levels. Tachycardia and hypotension (choice B) can be seen in AKI but do not reflect the urgency of addressing anuria. Decreased urine output (choice C) is concerning but not as critical as the absence of urine production. Elevated blood urea nitrogen (BUN) levels (choice D) are indicative of kidney dysfunction but do not demand immediate action as anuria does.
4. A client with a history of hypertension is admitted with shortness of breath and chest pain. Which diagnostic test should the nurse anticipate preparing the client for first?
- A. Electrocardiogram (ECG)
- B. Chest X-ray
- C. Pulmonary function tests (PFTs)
- D. Arterial blood gases (ABGs)
Correct answer: A
Rationale: The correct answer is A: Electrocardiogram (ECG). An ECG should be performed first to assess for cardiac ischemia in a client presenting with shortness of breath and chest pain. This test helps in evaluating the electrical activity of the heart and can identify signs of myocardial infarction or other cardiac issues. Choice B, Chest X-ray, may be ordered after the ECG to assess for pulmonary conditions like pneumonia or effusions. Choice C, Pulmonary function tests (PFTs), are used to evaluate lung function and are not the primary diagnostic tests for a client with symptoms of cardiac origin. Choice D, Arterial blood gases (ABGs), may provide information about oxygenation but are not the initial test indicated for a client with suspected cardiac issues.
5. In caring for a client with a PCA infusion of morphine sulfate through the right cephalic vein, the nurse assesses that the client is lethargic with a blood pressure of 90/60 mm Hg, a pulse rate of 118 beats per minute, and a respiratory rate of 8 breaths per minute. What assessment should the nurse perform next?
- A. Note the appearance and patency of the client's peripheral IV site.
- B. Palpate the volume of the client's right radial pulse.
- C. Auscultate the client's breath sounds bilaterally.
- D. Observe the amount and dose of morphine in the PCA pump syringe.
Correct answer: D
Rationale: In this scenario, the client is presenting with signs of potential opioid overdose, such as lethargy, hypotension, tachycardia, and bradypnea. The next assessment the nurse should perform is to observe the amount and dose of morphine in the PCA pump syringe. This evaluation is crucial in determining if the client is receiving an excessive amount of morphine, leading to the observed symptoms. Checking the PCA pump syringe will provide essential information to address the client's condition promptly and prevent further complications. Choices A, B, and C are not the priority in this situation as they do not directly address the potential cause of the client's symptoms related to morphine administration.
