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. 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.
3. Following a craniotomy, why did the nurse position the client in low Fowler's position?
- A. To promote comfort.
- B. To promote drainage from the operation site.
- C. To promote thoracic expansion.
- D. To prevent circulatory overload.
Correct answer: B
Rationale: Positioning the client in low Fowler's position after a craniotomy is essential to promote drainage from the operation site. This position helps prevent fluid accumulation, facilitates the removal of excess fluid or blood, and aids in the healing process. Choice A is incorrect because comfort, while important, is not the primary reason for this specific positioning. Choice C is incorrect as thoracic expansion is not the main concern following a craniotomy. Choice D is incorrect as circulatory overload is not typically addressed by positioning in low Fowler's position post-craniotomy.
4. A client with a diagnosis of chronic obstructive pulmonary disease (COPD) is receiving oxygen via nasal cannula at 4 liters per minute. Which assessment finding indicates a need for immediate action?
- A. The client's respiratory rate is 14 breaths per minute.
- B. The client's oxygen saturation is 92%.
- C. The client reports shortness of breath.
- D. The client's respiratory rate is 24 breaths per minute.
Correct answer: C
Rationale: A report of shortness of breath (C) indicates that the client is not tolerating the oxygen therapy well and may need an adjustment. Shortness of breath is a critical symptom in a client with COPD, as it signifies potential respiratory distress. A respiratory rate of 14 (A) is within an acceptable range for a client with COPD and does not require immediate action. An oxygen saturation of 92% (B) is slightly lower but still acceptable in COPD patients. Although a respiratory rate of 24 (D) is higher, it is not as immediately concerning as shortness of breath in this context.
5. A client is admitted with a fever of unknown origin. To assess fever patterns, which intervention should the nurse implement?
- A. Document the client’s temperature fluctuations
- B. Assess for flushed, warm skin consistently
- C. Measure temperature at regular intervals
- D. Use different sites for temperature measurement
Correct answer: C
Rationale: To assess fever patterns accurately, the nurse should measure the client’s temperature at regular intervals. This approach helps in identifying the pattern of fever spikes and fluctuations, which can provide valuable information for diagnostic and treatment purposes. Assessing for flushed, warm skin or documenting circadian rhythms may not directly reveal the fever pattern, while varying temperature measurement sites could lead to inconsistent readings. Therefore, measuring temperature at regular intervals is the most appropriate intervention to identify fever patterns in this scenario.
