HESI LPN
HESI Practice Test for Fundamentals
1. The nurse is assessing a 17-year-old female client with bulimia. Which of the following laboratory reports would the nurse anticipate?
- A. Increased serum glucose
- B. Decreased albumin
- C. Decreased potassium
- D. Increased sodium retention
Correct answer: C
Rationale: The correct answer is C, 'Decreased potassium.' Clients with bulimia often have decreased potassium levels due to frequent vomiting, which causes a loss of this essential electrolyte. This loss can lead to various complications such as cardiac arrhythmias. Option A, 'Increased serum glucose,' is not typically associated with bulimia. Option B, 'Decreased albumin,' is more related to malnutrition or liver disease rather than bulimia. Option D, 'Increased sodium retention,' is not a common finding in clients with bulimia; instead, they may experience electrolyte imbalances like hyponatremia due to purging behaviors.
2. A client is 24 hours postoperative following an inguinal hernia repair. The client is tolerating clear liquids well, has active bowel sounds, and is expressing a desire for “real food.†The nurse tells the client, “I will call the surgeon and ask for a change in diet.†The surgeon hears the nurse’s report and prescribes a full liquid diet. The nurse used which of the following levels of critical thinking?
- A. Basic
- B. Commitment
- C. Complex
- D. Integrity
Correct answer: C
Rationale: The nurse demonstrated complex critical thinking by assessing the client's condition, evaluating the need for a change, and making a recommendation to the surgeon. In this scenario, the nurse went beyond simply following instructions or making routine decisions (basic critical thinking). There was a depth of analysis and decision-making involved, showing a higher level of critical thinking than basic or commitment levels. Integrity is about adherence to ethical principles and honesty, not directly related to the critical thinking process.
3. A client is drawing up and mixing insulin under the observation of a nurse. Which of the following findings should the nurse identify as an indication that psychomotor learning has taken place?
- A. The client is able to discuss the appropriate technique.
- B. The client is able to demonstrate the appropriate technique.
- C. The client states an understanding of the process.
- D. The client is able to write the steps on a piece of paper.
Correct answer: B
Rationale: The correct answer is B because the ability to demonstrate the appropriate technique shows that the client has acquired the psychomotor skills needed for insulin preparation. Merely discussing, stating an understanding, or writing the steps does not confirm that the client can physically perform the task correctly. Being able to demonstrate indicates practical application and mastery of the skill. Choice A is incorrect because discussing the technique does not necessarily mean the client can physically perform it. Choice C is incorrect as stating an understanding does not guarantee the client's ability to perform the task. Choice D is incorrect because writing the steps does not assess the client's physical execution of the technique.
4. A client with a history of diabetes mellitus is experiencing polyuria, polydipsia, and polyphagia. What is the most important action for the nurse to take?
- A. Monitor the client's blood glucose level.
- B. Encourage the client to increase fluid intake.
- C. Administer insulin as prescribed.
- D. Assess the client's urine output.
Correct answer: A
Rationale: The most critical action for the nurse to take when a client with diabetes mellitus presents with symptoms of hyperglycemia such as polyuria, polydipsia, and polyphagia is to monitor the client's blood glucose level. This action helps in assessing the client's current glycemic status and guides further interventions. Encouraging increased fluid intake (Choice B) may be beneficial in managing dehydration caused by polyuria, but it does not address the underlying cause of hyperglycemia. Administering insulin as prescribed (Choice C) may be necessary based on the blood glucose monitoring results, but monitoring should precede any medication administration. Assessing the client's urine output (Choice D) is important but does not directly address the primary concern of evaluating and managing hyperglycemia in a client with diabetes.
5. The client with congestive heart failure (CHF) is receiving furosemide (Lasix). Which laboratory value should the healthcare provider monitor closely?
- A. Potassium
- B. Sodium
- C. Calcium
- D. Magnesium
Correct answer: A
Rationale: Correct! When a client is taking furosemide (Lasix), monitoring potassium levels is crucial due to the potential for hypokalemia. Furosemide is a loop diuretic that can lead to potassium loss through increased urine output. Low potassium levels can predispose the client to cardiac dysrhythmias. Sodium, calcium, and magnesium levels are not typically affected by furosemide to the same extent as potassium, making them less critical to monitor in this scenario.
