HESI Fundamentals Study Guide
1. A healthcare professional is caring for a client who has a new prescription for antihypertensive medication. Prior to administering the medication, the healthcare professional uses an electronic database to gather information about the medication and the effects it might have on this client. Which of the following components of critical thinking is the healthcare professional using when reviewing the medication information?
- A. Knowledge
- B. Experience
- C. Intuition
- D. Competence
Correct answer: A
Rationale: The correct answer is A: Knowledge. In this scenario, the healthcare professional is utilizing knowledge by gathering and applying information about the medication. Choice B, Experience, is not the best option as the focus is on accessing information about the medication rather than personal experience. Choice C, Intuition, refers to a gut feeling or instinct, which is not evident in the scenario. Choice D, Competence, relates more to overall ability and proficiency rather than the specific act of seeking information.
2. Which serum blood finding in diabetic ketoacidosis alerts the nurse that immediate action is required?
- A. pH below 7.3
- B. Potassium of 5.0
- C. HCT of 60
- D. PaO2 of 79%
Correct answer: C
Rationale: A hematocrit (HCT) of 60 indicates severe dehydration, a critical condition in diabetic ketoacidosis that requires immediate intervention. Severe dehydration can lead to hypovolemic shock and organ failure. While a low pH below 7.3 is indicative of acidosis, it may not require immediate action compared to severe dehydration. A potassium level of 5.0 is within the normal range and not a critical finding in this scenario. PaO2 of 79% reflects oxygenation status, which is important but not the most critical finding requiring immediate action in diabetic ketoacidosis.
3. A client is postoperative following knee arthroplasty and requires the use of a thigh-length sequential compression device. Which of the following actions should the nurse take?
- A. Ensure two fingers can fit under the sleeves.
- B. Ensure the device is not too tight to impede circulation.
- C. Position the client comfortably before applying the device.
- D. Use the device continuously to prevent blood clots.
Correct answer: A
Rationale: The correct action for the nurse to take when applying a thigh-length sequential compression device to a postoperative client is to ensure that two fingers can fit under the sleeves. This action helps prevent the device from being too tight, which could impede circulation. Choice B is incorrect because the device should not be too tight, as it could lead to circulation issues. Choice C is incorrect as the client should be in a comfortable position, not necessarily supine. Choice D is incorrect as sequential compression devices are typically used continuously to prevent blood clots.
4. A client scheduled for abdominal surgery reports being worried. Which of the following actions should the nurse take?
- A. Offer information on a relaxation technique and ask if the client is interested in trying it.
- B. Request a social worker to see the client to discuss meditation.
- C. Attempt to use biofeedback techniques with the client.
- D. Tell the client many people feel the same way before surgery and to think of something else.
Correct answer: A
Rationale: Offering relaxation techniques addresses the client's immediate concern by providing a proactive approach to managing anxiety. It shows empathy and offers a practical solution. Requesting a social worker for meditation (Choice B) may not be the most direct response to the client's immediate worry. Attempting biofeedback (Choice C) may not be suitable without the client's interest or consent. Telling the client to think of something else (Choice D) dismisses the client's feelings and does not provide constructive support.
5. A client with chronic kidney disease is receiving epoetin alfa (Epogen). Which laboratory value should the nurse monitor to determine the effectiveness of this medication?
- A. Serum creatinine
- B. Hemoglobin
- C. Blood urea nitrogen (BUN)
- D. Platelet count
Correct answer: B
Rationale: The correct answer is B: Hemoglobin. Epoetin alfa (Epogen) is a medication commonly used in clients with chronic kidney disease to stimulate red blood cell production. Monitoring hemoglobin levels is crucial to assess the effectiveness of epoetin alfa therapy. Hemoglobin levels reflect the oxygen-carrying capacity of the blood and indicate if the medication is successfully treating anemia associated with chronic kidney disease. Option A, serum creatinine, is a marker of kidney function, not the primary indicator of epoetin alfa effectiveness. Option C, blood urea nitrogen (BUN), is a measure of kidney function and hydration status. Option D, platelet count, assesses clotting ability and is unrelated to monitoring the effectiveness of epoetin alfa in treating anemia in chronic kidney disease.
