HESI LPN
HESI Fundamentals Exam
1. A healthcare professional is caring for a client who has pharyngeal diphtheria. Which of the following types of transmission precautions should the healthcare professional initiate?
- A. Contact
- B. Droplet
- C. Airborne
- D. Protective
Correct answer: B
Rationale: The correct answer is B: Droplet. Droplet precautions are required for infections that spread via droplets larger than 5 microns in diameter, such as pharyngeal diphtheria. Contact precautions are used for diseases that spread by direct or indirect contact. Airborne precautions are for diseases that spread through small particles in the air. Protective precautions are not a standard precautionary measure for specific infections like pharyngeal diphtheria.
2. What is an episiotomy?
- A. A surgical incision of the perineum to prevent tearing during delivery.
- B. Releasing the red plug from the cervix just before crowning occurs.
- C. An incision in the abdomen with which the baby can be delivered through.
- D. The severance of the umbilical cord between mother and child.
Correct answer: A
Rationale: An episiotomy is a surgical incision of the perineum to prevent tearing during delivery. This procedure is performed to widen the vaginal opening and facilitate childbirth. Choice B is incorrect as it describes the expulsion of the mucus plug, not an episiotomy. Choice C is incorrect as it refers to a different procedure, a cesarean section, where the baby is delivered through an incision in the abdomen. Choice D is incorrect as it pertains to cutting the umbilical cord, which is not related to an episiotomy.
3. The nurse is caring for a client with a newly placed colostomy. Which statement by the client indicates a need for additional teaching?
- A. I will need to change the colostomy bag every day.
- B. I should avoid foods that can cause gas, such as beans and carbonated drinks.
- C. I need to empty the colostomy bag when it is one-third to one-half full.
- D. I will need to take care of the skin around the stoma to prevent irritation.
Correct answer: A
Rationale: The correct answer is A. Changing the colostomy bag every day is not necessary; it should be changed as needed, usually every 3-7 days. This statement indicates a need for additional teaching as frequent changes can irritate the skin and are not typically required. Choices B, C, and D are all correct statements regarding colostomy care. Avoiding gas-producing foods, emptying the bag when it is one-third to one-half full, and taking care of the skin around the stoma are all essential aspects of colostomy care to prevent complications and maintain skin integrity.
4. The client had gastric bypass surgery yesterday. Which intervention is most important for the nurse to implement during the first 24 postoperative hours?
- A. Insert an indwelling urinary catheter
- B. Monitor for the appearance of an incisional hernia
- C. Instruct the client to eat small frequent meals
- D. Measure hourly urinary output
Correct answer: D
Rationale: Monitoring hourly urinary output is crucial during the first 24 postoperative hours to assess kidney function, fluid balance, and early detection of complications like dehydration or inadequate kidney perfusion. Inserting an indwelling urinary catheter is not routinely necessary after gastric bypass surgery unless there are specific indications. Monitoring for an incisional hernia is important but not the highest priority in the immediate postoperative period. Instructing the client to eat small frequent meals is essential for long-term dietary management after gastric bypass surgery, but not the most critical intervention during the initial 24 hours.
5. A nurse is caring for an infant with intractable vomiting. For what complication is it most important for the nurse to assess?
- A. Acidosis
- B. Alkalosis
- C. Hyperkalemia
- D. Hypernatremia
Correct answer: B
Rationale: When an infant experiences intractable vomiting, it can lead to the loss of stomach acids, resulting in metabolic alkalosis. Alkalosis is characterized by elevated blood pH and can lead to serious complications. Assessing for alkalosis is essential in this scenario to monitor and manage the infant's condition. Choices A, C, and D are incorrect because in this context, the primary concern is the metabolic imbalance caused by excessive vomiting, leading to alkalosis rather than acidosis, hyperkalemia, or hypernatremia.
