HESI LPN
LPN Nutrition Practice Test
1. How should the nurse manage a child with acute lymphoblastic leukemia (ALL) who is receiving chemotherapy?
- A. Avoid all physical activity
- B. Ensure strict infection control measures
- C. Increase daily caloric intake
- D. Limit fluid intake
Correct answer: B
Rationale: The correct answer is B: Ensure strict infection control measures. Children with acute lymphoblastic leukemia (ALL) who are undergoing chemotherapy have compromised immune systems, making them highly susceptible to infections. Implementing strict infection control measures, such as hand hygiene, limiting exposure to sick individuals, and maintaining a clean environment, is essential to prevent infections. Choice A is incorrect because avoiding all physical activity may not be necessary as long as the child's activity level is appropriate. Choice C is incorrect because increasing daily caloric intake is important to support the child's nutritional needs during treatment. Choice D is incorrect because limiting fluid intake is not typically recommended unless specifically advised by the healthcare provider.
2. How should a healthcare provider address a child's nutritional needs with a lactose intolerance diagnosis?
- A. Recommend lactose-free dairy products
- B. Increase dairy intake
- C. Encourage high-fiber diet
- D. Use oral probiotics only
Correct answer: A
Rationale: In managing lactose intolerance in a child, recommending lactose-free dairy products is crucial. These products help address the child's nutritional needs without causing symptoms related to lactose consumption. Choice B is incorrect because increasing dairy intake would exacerbate symptoms in a lactose-intolerant individual as they cannot digest lactose properly. Choice C, encouraging a high-fiber diet, is not directly related to managing lactose intolerance and may not address the primary issue of lactose malabsorption. Choice D, using oral probiotics only, may not be sufficient to address the child's nutritional needs in case of lactose intolerance as the main concern is avoiding lactose-containing products.
3. While caring for a client who is being mechanically ventilated, the nurse responds to a high-pressure alarm on the ventilator. Which assessment finding warrants immediate intervention by the nurse?
- A. Endotracheal cuff pressure greater than 25 cm H2O.
- B. Decreased lung compliance during ventilation.
- C. Bilateral crackles with increased secretions.
- D. Restless client who is biting the endotracheal tube.
Correct answer: D
Rationale: A restless client biting the endotracheal tube can increase airway resistance, triggering the high-pressure alarm and indicating a need for immediate intervention. This behavior can lead to complications such as dislodgement of the tube or airway obstruction. Endotracheal cuff pressure greater than 25 cm H2O, decreased lung compliance, and bilateral crackles with increased secretions are important assessments but do not directly address the urgent need to intervene when a high-pressure alarm is triggered.
4. A client with a history of hypertension is admitted to the hospital for a suspected myocardial infarction. Which of the following is the priority nursing action?
- A. Administer oxygen as prescribed
- B. Perform an ECG
- C. Obtain a detailed health history
- D. Monitor vital signs regularly
Correct answer: B
Rationale: The priority nursing action in this scenario is to perform an ECG. An ECG is crucial in confirming myocardial infarction promptly and guiding immediate treatment decisions. Administering oxygen as prescribed is important but not the priority over confirming the diagnosis. Obtaining a detailed health history is relevant but does not take precedence over immediate diagnostic confirmation. While monitoring vital signs regularly is essential, performing an ECG is the priority action in this scenario to guide timely management.
5. What maternal factor should the nurse identify as having the greatest impact on the development of spina bifida occulta in a newborn?
- A. Short interval between pregnancies
- B. Folic acid deficiency
- C. Preeclampsia
- D. Tobacco use
Correct answer: B
Rationale: Folic acid deficiency during pregnancy is a well-known risk factor for neural tube defects, including spina bifida occulta, making supplementation critical in prenatal care. Folic acid plays a crucial role in neural tube formation during early pregnancy. Short intervals between pregnancies do not directly impact the development of spina bifida occulta. Preeclampsia is a hypertensive disorder of pregnancy and is not directly linked to spina bifida occulta. While tobacco use during pregnancy has various adverse effects, it is not the primary factor influencing the development of spina bifida occulta in newborns.
