HESI LPN
HESI Practice Test for Fundamentals
1. During an abdominal examination, a nurse in a provider’s office determines that a client has abdominal distention. The protrusion is at midline, the skin over the area is taut, and the nurse notes no involvement of the flanks. Which of the following possible causes of distention should the nurse suspect?
- A. Fat
- B. Fluid
- C. Flatus
- D. Hernias
Correct answer: D
Rationale: The correct answer is 'Hernias.' Abdominal distention with a midline protrusion, taut skin, and no involvement of the flanks is characteristic of hernias. Hernias are caused by a weakness in the abdominal wall, allowing organs or tissues to protrude through. Fluid accumulation (ascites) typically presents with a more generalized distention, while fat accumulation may cause more diffuse distension rather than a focal midline protrusion. Flatus, or gas, would not typically present with a visible midline protrusion and taut skin like hernias.
2. The nurse admits a 7 year-old to the emergency room after a leg injury. The x-rays show a femur fracture near the epiphysis. The parents ask what will be the outcome of this injury. The appropriate response by the nurse should be which of these statements?
- A. The injury is expected to heal quickly because of thin periosteum.
- B. In some instances the result is a retarded bone growth.
- C. Bone growth is stimulated in the affected leg.
- D. This type of injury shows more rapid union than that of younger children.
Correct answer: B
Rationale: A fracture near the epiphysis can result in retarded bone growth, so this should be communicated to the parents.
3. A nurse is caring for a group of clients. How should the nurse prevent the spread of infection?
- A. Place a client with TB in a negative pressure room.
- B. Use standard precautions only.
- C. Place a client with TB in a private room.
- D. Use barrier precautions only.
Correct answer: A
Rationale: The correct answer is to place a client with TB in a negative pressure room. Tuberculosis (TB) is an airborne infectious disease, and placing the client in a negative pressure room helps prevent the spread of the infection by containing and filtering the air within the room. Standard precautions (Choice B) are important for preventing the spread of infection in general, but specific precautions are needed for airborne diseases like TB. Placing the client in a private room (Choice C) may not provide adequate ventilation and containment of airborne pathogens. Using barrier precautions (Choice D) alone is not sufficient for preventing the airborne transmission of TB.
4. A client has acute renal failure. Which of the following assessments provides the most accurate measure of the client's fluid status?
- A. Daily weight
- B. Intake and output
- C. Urine specific gravity
- D. Peripheral edema
Correct answer: A
Rationale: Daily weight is the most accurate measure of fluid status in a client with acute renal failure. Fluctuations in weight reflect changes in body fluid volume, including both fluid retention or loss. Intake and output, while important, may not always accurately reflect overall fluid status as it does not account for insensible losses. Urine specific gravity can provide information on urine concentration but does not offer a comprehensive assessment of overall fluid status. Peripheral edema, although a sign of fluid retention, is a more subjective assessment and may not always accurately reflect the client's fluid status like daily weight monitoring does.
5. The client is advised to take dexamethasone (Decadron) with food or milk. What is the physiological basis for this advice?
- A. Inhibits pepsin production
- B. Stimulates hydrochloric acid production
- C. Delays stomach emptying time
- D. Reduces hydrochloric acid production
Correct answer: B
Rationale: The correct answer is B: Stimulates hydrochloric acid production. Dexamethasone can stimulate the production of hydrochloric acid in the stomach, which may lead to irritation of the stomach lining. Taking dexamethasone with food or milk helps to neutralize or buffer the acid, reducing the risk of stomach irritation. Choice A is incorrect because dexamethasone does not inhibit pepsin production. Choice C is incorrect as dexamethasone does not slow stomach emptying time. Choice D is incorrect as dexamethasone does not reduce hydrochloric acid production.
