HESI LPN
Fundamentals of Nursing HESI
1. A client with a history of alcoholism is admitted with confusion and ataxia. The LPN/LVN recognizes that these symptoms may be related to a deficiency in which vitamin?
- A. Vitamin A
- B. Vitamin C
- C. Vitamin D
- D. Vitamin B1 (Thiamine)
Correct answer: D
Rationale: The correct answer is Vitamin B1 (Thiamine). Vitamin B1 deficiency, also known as Thiamine deficiency, is common in clients with a history of alcoholism. Thiamine is essential for proper brain function, and its deficiency can lead to neurological symptoms such as confusion and ataxia. Vitamin A, C, and D deficiencies do not typically present with confusion and ataxia in the context of alcoholism. Vitamin A deficiency mainly affects vision, Vitamin C deficiency leads to scurvy with symptoms like bleeding gums, and Vitamin D deficiency is associated with bone disorders. Therefore, they are not the correct choices in this scenario.
2. During a mass casualty event, a nurse is caring for multiple clients. Which of the following clients is the nurse’s priority?
- A. A client who received crush injuries to the chest and abdomen and is expected to die.
- B. A client who has a 4-inch laceration to the head.
- C. A client who has partial-thickness and full-thickness burns to his face, neck, and chest.
- D. A client who has a fractured fibula and tibia.
Correct answer: C
Rationale: During a mass casualty event, the priority client for the nurse is the one with partial-thickness and full-thickness burns to the face, neck, and chest. Clients with severe burns in critical areas require immediate attention due to the potential for life-threatening complications such as airway compromise, fluid loss, and infection. Crush injuries and fractures, although serious, are generally less urgent in comparison and can be managed after addressing the burns. Therefore, the client with burns to the face, neck, and chest should be the nurse's priority over the other clients described.
3. When assessing a male client, the nurse finds that he is fatigued and is experiencing muscle weakness, leg cramps, and cardiac dysrhythmias. Based on these findings, the nurse plans to check the client's laboratory values to validate the existence of which condition?
- A. Hyperphosphatemia
- B. Hypocalcemia
- C. Hypermagnesemia
- D. Hypokalemia
Correct answer: D
Rationale: The symptoms of muscle weakness, leg cramps, and cardiac dysrhythmias are indicative of hypokalemia, a condition characterized by low potassium levels. Checking the client's laboratory values for potassium will help confirm this diagnosis. Hyperphosphatemia (Choice A) is an elevated phosphate level in the blood, which is not consistent with the symptoms described. Hypocalcemia (Choice B) is a low calcium level and typically presents with different symptoms than those mentioned in the scenario. Hypermagnesemia (Choice C) is an excess of magnesium in the blood and does not align with the symptoms of muscle weakness, leg cramps, and cardiac dysrhythmias observed in the client.
4. The healthcare provider prescribes furosemide (Lasix) 15 mg IV stat. On hand is Lasix 20 mg/2 ml. How many milliliters should the LPN/LVN administer?
- A. 1 ml.
- B. 1.5 ml.
- C. 1.75 ml.
- D. 2 ml.
Correct answer: B
Rationale: To calculate the correct dose of 15 mg, the LPN/LVN should administer 1.5 ml of Lasix (20 mg/2 ml). This calculation ensures precise dosing. Choice A (1 ml) is too low and would provide only 10 mg, while choice C (1.75 ml) and choice D (2 ml) would exceed the prescribed dose, resulting in potential adverse effects. It is important for the LPN/LVN to administer the exact prescribed dose to ensure therapeutic efficacy and avoid unnecessary complications.
5. While suctioning a client's nasopharynx, the nurse observes that the client's oxygen saturation remains at 94%, which is the same reading obtained prior to starting the procedure. What action should the nurse take in response to this finding?
- A. Complete the intermittent suction of the nasopharynx.
- B. Reposition the pulse oximeter clip to obtain a new reading.
- C. Stop suctioning until the pulse oximeter reading is above 95%.
- D. Apply an oxygen mask over the client's nose and mouth.
Correct answer: A
Rationale: The correct action for the nurse to take in this situation is to complete the intermittent suction of the nasopharynx. Since the oxygen saturation remains stable at 94%, which was the initial reading, it indicates that the procedure is not causing a significant drop in oxygen levels. Stopping the suctioning or applying oxygen may not be necessary as the saturation level is within an acceptable range. Repositioning the pulse oximeter clip is unlikely to change the reading significantly. Therefore, completing the procedure maintains care consistency and effectiveness, ensuring proper airway management without unnecessary interventions. Choices B, C, and D are incorrect because repositioning the pulse oximeter clip, stopping suctioning until a higher reading is achieved, and applying oxygen are not warranted based on the stable oxygen saturation level of 94% throughout the procedure.
