HESI LPN
HESI PN Exit Exam 2024 Quizlet
1. A client who is at full-term gestation is in active labor and complains of a cramp in her leg. Which intervention should the PN implement?
- A. Massage the calf and foot
- B. Elevate the leg above the heart
- C. Check the pedal pulse in the affected leg
- D. Extend the leg and flex the foot
Correct answer: D
Rationale: During labor, muscle cramps are common due to prolonged muscle tension. The correct intervention to alleviate a cramp in the leg is to extend the leg and flex the foot. This action helps relieve the muscle spasm by stretching and contracting the muscles. Massaging the calf and foot (Choice A) may not be as effective in relieving the cramp as extending and flexing the leg. Elevating the leg above the heart (Choice B) is not necessary and may not directly address the cramp. Checking the pedal pulse (Choice C) is important for assessing circulation, but it does not directly address the muscle cramp.
2. When reviewing a client’s fluid and electrolyte status, what should the nurse report to the provider?
- A. Potassium 5.4
- B. Sodium 140
- C. Calcium 8.6
- D. Magnesium 2.0
Correct answer: A
Rationale: The correct answer is A: 'Potassium 5.4'. A potassium level of 5.4 is elevated (normal range is typically 3.5-5.0 mEq/L) and may indicate hyperkalemia, which can have serious cardiac implications. Elevated potassium levels can lead to life-threatening arrhythmias, so immediate reporting and intervention are necessary. Choice B, 'Sodium 140', falls within the normal range (135-145 mEq/L) and does not require immediate reporting. Choice C, 'Calcium 8.6', falls within the normal range (8.5-10.5 mg/dL) and is not an immediate concern. Choice D, 'Magnesium 2.0', is within the normal range (1.5-2.5 mEq/L) and does not need urgent reporting. Therefore, the nurse should prioritize reporting the elevated potassium level as it poses the most immediate risk.
3. A client is to receive 10 mEq of KCl diluted in 250 ml of normal saline over 4 hours. At what rate should the LPN/LVN set the client's intravenous infusion pump?
- A. 13 ml/hour
- B. 63 ml/hour
- C. 80 ml/hour
- D. 125 ml/hour
Correct answer: B
Rationale: To calculate the correct rate of infusion, divide the total volume by the total time: 250 ml / 4 hours = 62.5 ml/hour, which is rounded up to 63 ml/hour. This rate ensures the proper administration of the KCl over the 4-hour period. Choice A (13 ml/hour) is incorrect as it does not match the calculated rate. Choices C (80 ml/hour) and D (125 ml/hour) are also incorrect as they do not correspond to the calculated rate needed for the specified time frame.
4. A client who is receiving chemotherapy for cancer treatment is experiencing nausea and vomiting. What is the best intervention for the LPN/LVN to implement?
- A. Offer the client small, frequent meals.
- B. Provide antiemetic medication as prescribed.
- C. Encourage the client to drink clear liquids.
- D. Assist the client with oral care.
Correct answer: B
Rationale: The best intervention for a client experiencing chemotherapy-induced nausea and vomiting is to provide antiemetic medication as prescribed. This medication helps in managing and reducing nausea and vomiting, providing relief to the client. Offering small, frequent meals (Choice A) may not address the underlying cause of the symptoms. Encouraging clear liquid intake (Choice C) may not be effective in controlling nausea and vomiting associated with chemotherapy. Assisting with oral care (Choice D) is important for overall comfort but may not directly address the symptoms of nausea and vomiting.
5. What is the most common cause of vaginal bleeding immediately after birth?
- A. Uterine atony
- B. Genital lacerations
- C. Abnormal clotting mechanism
- D. Endometritis
Correct answer: A
Rationale: Vaginal bleeding immediately after birth is most often due to uterine atony, which is the failure of the uterus to contract following delivery. This results in inadequate compression of blood vessels at the placental site, leading to hemorrhage. Genital lacerations and abnormal clotting mechanisms can also cause bleeding but are less common immediately after birth compared to uterine atony. Endometritis, inflammation of the lining of the uterus, usually presents with symptoms like fever and pelvic pain rather than immediate postpartum bleeding.
