HESI LPN
Pediatric HESI Test Bank
1. An infant who has had diarrhea for 3 days is admitted in a lethargic state and is breathing rapidly. The parent states that the baby has been ingesting formula, although not as much as usual, and cannot understand the sudden change. What explanation should the nurse give the parent?
- A. Cellular metabolism is unstable in young children.
- B. The proportion of water in the body is less than in adults.
- C. Renal function is immature in children until they reach school age.
- D. The extracellular fluid requirement per unit of body weight is greater than in adults.
Correct answer: D
Rationale: The correct answer is D. Infants have a higher extracellular fluid requirement per unit of body weight, making them more susceptible to dehydration and electrolyte imbalances during illnesses such as diarrhea. Choice A is incorrect because cellular metabolism being unstable is not the primary explanation for the symptoms described. Choice B is incorrect as the proportion of water in the body alone does not fully explain the increased risk of dehydration in infants. Choice C is incorrect because while renal function is immature in children, it is not the most relevant factor in this scenario compared to the increased fluid requirements.
2. When caring for a child diagnosed with cystic fibrosis, what is the priority nursing intervention?
- A. Administering pancreatic enzymes
- B. Providing respiratory therapy
- C. Encouraging physical activity
- D. Encouraging frequent handwashing
Correct answer: A
Rationale: The priority nursing intervention when caring for a child with cystic fibrosis is administering pancreatic enzymes. Cystic fibrosis is a genetic disorder that affects the digestive and respiratory systems. Administering pancreatic enzymes is crucial in aiding digestion as patients with cystic fibrosis often have pancreatic insufficiency. While providing respiratory therapy and encouraging physical activity are important aspects of care for individuals with cystic fibrosis, administering pancreatic enzymes takes precedence in addressing the malabsorption issues associated with the condition. Encouraging frequent handwashing is also essential in infection control, but it is not the priority intervention specifically related to managing cystic fibrosis.
3. Which task could the nurse safely delegate to the UAP?
- A. Oral feeding of a two-year-old child after application of a hip spica cast
- B. Assessment of the placement and patency of an NG tube
- C. Participation in staff rounds to record notes regarding client goals
- D. Evaluation of a client's incisional pain following narcotic administration
Correct answer: A
Rationale: The correct answer is A because oral feeding of a stable child is a task that can be safely delegated to a UAP. This task does not require nursing assessment or clinical judgment. Choice B involves assessment, which requires the nurse's clinical judgment. Choice C involves recording client goals during staff rounds, which may require interpretation and understanding of the goals set. Choice D involves evaluating a client's pain following medication administration, which requires assessment and clinical judgment by a nurse.
4. A nurse is providing teaching to a newly licensed nurse about the care of a client who has MRSA. Which of the following statements by the newly licensed nurse indicates an understanding of teaching?
- A. I will place the client in a private room
- B. I will tell the client’s visitors to wear a mask when they are within 3 feet of the client
- C. I will remove my gown after leaving the client’s room
- D. I will wear an N95 respirator mask when caring for the client
Correct answer: A
Rationale: The correct answer is A: 'I will place the client in a private room.' Placing the client in a private room helps prevent the spread of MRSA, a contact precaution. Choice B is incorrect because visitors should be following standard precautions for MRSA, not just wearing a mask within a specific distance. Choice C is incorrect as the gown should be removed before exiting the client's room to prevent the spread of MRSA. Choice D is incorrect as an N95 respirator mask is not typically required for the care of a client with MRSA; standard precautions are usually sufficient.
5. When reinforcing diet teaching for a client diagnosed with hypokalemia, which foods should the PN encourage the client to eat? Select All That Apply
- A. Orange juice, oranges, bananas
- B. All are applicable
- C. Collard greens, kale, turnips
- D. Soybeans, lima beans, spinach
Correct answer: B
Rationale: The correct answer is B: All are applicable. Foods rich in potassium, such as orange juice, oranges, bananas, collard greens, kale, soybeans, lima beans, and spinach, are essential for managing hypokalemia. These options provide a significant source of potassium, which helps in maintaining normal heart and muscle function. Choice A is incorrect because it does not include all the appropriate potassium-rich foods. Choice C is incorrect as it only mentions vegetables rich in potassium, missing out on other essential sources like fruits and beans. Choice D is incorrect as it lacks key potassium-rich foods like oranges and bananas.
