HESI Fundamentals Practice Exam
1. The nurse is providing discharge teaching to a client with a new prescription for warfarin (Coumadin). Which dietary instruction should the nurse include?
- A. Avoid foods high in vitamin K
- B. Increase intake of leafy green vegetables
- C. Consume a consistent amount of foods high in potassium
- D. Limit intake of high-protein foods
Correct answer: A
Rationale: The correct dietary instruction for a client taking warfarin is to avoid foods high in vitamin K. Warfarin is an anticoagulant that works by inhibiting vitamin K-dependent clotting factors. Consuming foods high in vitamin K, such as leafy green vegetables, can antagonize the effects of warfarin, potentially leading to treatment inefficacy or fluctuations in anticoagulation levels. Therefore, clients on warfarin therapy should be advised to avoid foods high in vitamin K to maintain the effectiveness of the medication. Choices B, C, and D are incorrect because increasing leafy green vegetables (choice B) would introduce more vitamin K, consuming a consistent amount of foods high in potassium (choice C) is not directly related to warfarin therapy, and limiting high-protein foods (choice D) is not a specific concern for clients on warfarin therapy.
2. When assessing for orthostatic hypotension during blood pressure measurement, what action should the nurse implement first?
- A. Position the client supine for a few minutes
- B. Assist the client to stand at the bedside
- C. Apply the blood pressure cuff securely
- D. Record the client’s pulse rate and rhythm
Correct answer: A
Rationale: When assessing for orthostatic hypotension, the initial step is to position the client supine for a few minutes. This allows the body to adjust to the supine position before assessing blood pressure changes that may indicate orthostatic hypotension. By observing the blood pressure after the client has rested supine, the nurse can accurately assess for any drop in blood pressure upon standing, which is indicative of orthostatic hypotension. Choices B, C, and D are incorrect as they do not address the initial step in assessing for orthostatic hypotension, which is ensuring the client is positioned correctly to detect blood pressure changes upon standing.
3. The healthcare provider is caring for a client who is experiencing fluid volume deficit (dehydration). Which intervention should the healthcare provider implement to assess the effectiveness of fluid replacement therapy?
- A. Monitor daily weights
- B. Assess skin turgor
- C. Evaluate blood pressure trends
- D. Check urine specific gravity
Correct answer: A
Rationale: Monitoring daily weights is an accurate method to assess the effectiveness of fluid replacement therapy because changes in weight reflect changes in fluid balance. Fluid volume deficit can be objectively evaluated by monitoring daily weights as it provides a more precise measurement of fluid status over time. Assessing skin turgor (choice B) is subjective and may not provide as accurate or measurable data as monitoring daily weights. Evaluating blood pressure trends (choice C) can give information about circulatory status but may not directly reflect fluid volume status. Checking urine specific gravity (choice D) can indicate the concentration of urine but does not provide a comprehensive assessment of overall fluid balance like monitoring daily weights does.
4. A client with cirrhosis and ascites is receiving furosemide 40 mg BID. The pharmacy provides 20 mg tablets. How many tablets should the client receive each day? [Enter numeric value only]
- A. 4 tablets
- B. 3 tablets
- C. 2 tablets
- D. 1 tablet
Correct answer: A
Rationale: To calculate the total daily dose of furosemide needed, 40 mg BID (twice a day) is 80 mg/day. Since each tablet is 20 mg, the client should receive a total of 4 tablets per day (80 mg ÷ 20 mg per tablet = 4 tablets). Therefore, the correct answer is 4 tablets. Choice B (3 tablets) is incorrect because it does not provide the correct total daily dose. Choice C (2 tablets) is incorrect as it would not meet the required dose of 80 mg/day. Choice D (1 tablet) is incorrect as it would be insufficient to achieve the prescribed daily dose.
5. A client with chronic renal failure is receiving epoetin alfa (Epogen). Which laboratory test should the nurse monitor to evaluate the effectiveness of this medication?
- A. White blood cell count.
- B. Hemoglobin and hematocrit.
- C. Platelet count.
- D. Blood urea nitrogen (BUN) and creatinine.
Correct answer: B
Rationale: The correct answer is B: Hemoglobin and hematocrit. These are the primary laboratory tests to monitor the effectiveness of epoetin alfa (Epogen) in treating anemia. White blood cell count (A), platelet count (C), and blood urea nitrogen (BUN) and creatinine (D) are not directly related to the effects of this medication. Epoetin alfa stimulates the production of red blood cells, so monitoring hemoglobin and hematocrit levels helps assess the response to the treatment.
