HESI LPN
Nutrition Final Exam
1. What is one primary factor that influences nutrient needs in individuals?
- A. Age
- B. Gender
- C. Genetics
- D. Physical activity level
Correct answer: A
Rationale: Correct. Age is one of the primary factors influencing nutrient needs. Different life stages, such as infancy, childhood, adulthood, and old age, require varying amounts of nutrients. Gender (choice B) can influence nutrient needs to some extent, but age plays a more significant role. Genetics (choice C) may affect how individuals metabolize certain nutrients but is not a primary factor in determining overall nutrient needs. Physical activity level (choice D) can impact energy requirements but is not as fundamental as age in influencing overall nutrient needs.
2. What behavior is essential for preventing in a child postoperatively after undergoing heart surgery to repair defects associated with tetralogy of Fallot?
- A. Crying
- B. Coughing
- C. Straining at stool
- D. Unnecessary movement
Correct answer: C
Rationale: Preventing straining at stool is crucial postoperatively after heart surgery for tetralogy of Fallot to avoid increasing intrathoracic pressure and placing stress on the surgical site. This can help prevent complications and promote faster healing. While crying, coughing, and unnecessary movement are common postoperative behaviors, they are not specifically linked to worsening outcomes in this context. Straining at stool is particularly emphasized due to its potential to impact the surgical site and overall recovery process.
3. The nurse is assessing a client with portal hypertension. Which of the following findings would the nurse expect?
- A. Expiratory wheezes
- B. Blurred vision
- C. Ascites
- D. Dilated pupils
Correct answer: C
Rationale: Ascites is a common finding in clients with portal hypertension. Portal hypertension results in increased pressure in the portal vein, leading to the development of ascites, which is the accumulation of fluid in the abdominal cavity. Expiratory wheezes (Choice A) are associated with respiratory conditions. Blurred vision (Choice B) is more commonly linked to eye disorders or neurological issues. Dilated pupils (Choice D) can be related to neurological conditions or drug effects, but not specifically to portal hypertension.
4. A nurse is caring for an older, immobile patient whose condition requires a supine position. Which metabolic alteration will the nurse monitor for in this patient?
- A. Increased appetite
- B. Increased diarrhea
- C. Increased metabolic rate
- D. Increased pulse rate
Correct answer: D
Rationale: When an older, immobile patient is in a supine position, it increases cardiac workload, leading to an increased pulse rate. This is because the heart rate in older adults may not tolerate the additional workload. Choices A, B, and C are incorrect because an increased appetite, increased diarrhea, and increased metabolic rate are not directly associated with being immobile in a supine position. Increased appetite is more related to nutritional needs or certain medical conditions, increased diarrhea could be due to various causes, and an increased metabolic rate is not typically a direct consequence of lying supine.
5. A nurse in the emergency department is performing triage for a group of clients who were in a train crash. Which of the following clients should the nurse tag as emergent?
- A. A client who has an open fracture of the femur
- B. A client who has periorbital ecchymosis
- C. A client who has asymmetrical thorax
- D. A client who has a deep-partial thickness burn on the lower extremities
Correct answer: C
Rationale: In a triage situation, an asymmetrical thorax suggests a potentially life-threatening condition such as a pneumothorax or hemothorax, requiring immediate attention. This client should be tagged as emergent. Periorbital ecchymosis and deep-partial thickness burns, while concerning, may not indicate an immediate life-threatening situation. An open fracture of the femur, although serious, can be prioritized after addressing emergent cases.
