HESI LPN
HESI Fundamentals Practice Questions
1. The healthcare provider is caring for a client receiving total parenteral nutrition (TPN). Which laboratory value should be monitored closely to assess for complications?
- A. Serum sodium
- B. Serum calcium
- C. Blood urea nitrogen (BUN)
- D. Blood glucose
Correct answer: D
Rationale: The correct answer is D: Blood glucose. Monitoring blood glucose levels is crucial for clients receiving total parenteral nutrition (TPN) due to the high glucose content in TPN solutions. TPN delivers essential nutrients, including glucose, directly into the bloodstream. Clients on TPN are at risk of developing hyperglycemia due to the concentrated glucose infusion. Therefore, close monitoring of blood glucose levels is necessary to detect and prevent hyperglycemia-related complications such as osmotic diuresis, hyperosmolarity, and electrolyte imbalances. While serum sodium, serum calcium, and blood urea nitrogen (BUN) levels are important parameters in various clinical scenarios, they are not specifically associated with TPN administration. These values are not the primary indicators to assess for complications in clients receiving TPN.
2. Which cranial nerve is responsible for the sense of smell?
- A. Olfactory nerve
- B. Optic nerve
- C. Trigeminal nerve
- D. Vagus nerve
Correct answer: A
Rationale: The olfactory nerve (Cranial Nerve I) is indeed responsible for the sense of smell. It is located in the nasal cavity and transmits olfactory information to the brain. The optic nerve (Choice B) is responsible for vision, the trigeminal nerve (Choice C) is responsible for sensation in the face, and the vagus nerve (Choice D) is responsible for various functions such as heart rate, digestion, and speech. Therefore, the correct answer is the olfactory nerve (Choice A).
3. The healthcare provider is planning care for a 3-month-old infant immediately postoperative following placement of a ventriculoperitoneal shunt for hydrocephalus. The healthcare provider needs to
- A. Assess for abdominal distention
- B. Maintain the infant in an upright position
- C. Begin feeding formula when the infant is alert
- D. Pump the shunt to assess for proper function
Correct answer: A
Rationale: Assessing for abdominal distention is crucial in this situation as it can indicate a complication with the shunt or fluid accumulation. Abdominal distention may suggest an issue with the shunt placement, such as obstruction or overdrainage, which requires immediate intervention. Maintaining the infant in an upright position (Choice B) is not the priority immediately postoperatively following a ventriculoperitoneal shunt placement. Beginning formula feedings when the infant is alert (Choice C) may be appropriate but is not the priority over assessing for abdominal distention. Pumping the shunt to assess for proper function (Choice D) is not a recommended nursing intervention postoperatively and should be done by a qualified healthcare provider.
4. A client with schizophrenia is being treated with clozapine (Clozaril). What is the most important laboratory test for the LPN/LVN to monitor?
- A. White blood cell count.
- B. Liver function tests.
- C. Blood glucose levels.
- D. Platelet count.
Correct answer: A
Rationale: The most important laboratory test for an LPN/LVN to monitor for a client with schizophrenia being treated with clozapine is the white blood cell count. Clozapine treatment is associated with a risk of agranulocytosis, a severe drop in white blood cells, which can be life-threatening. Monitoring the white blood cell count regularly helps to detect this adverse effect early. Liver function tests (Choice B) are important to monitor with some antipsychotic medications but are not the most crucial for clozapine. Blood glucose levels (Choice C) are more relevant for monitoring in clients on medications like atypical antipsychotics that can cause metabolic side effects. Platelet count (Choice D) is not typically affected by clozapine therapy and is not the most important test to monitor in this case.
5. While assessing an 18-month-old child, a nurse observes that the toddler can crawl upstairs but needs assistance when climbing the stairs upright. What does this action indicate to the nurse?
- A. Presence of talipes equinovarus
- B. Reflective of neurologic damage
- C. Expected behavior in a toddler of this age
- D. Existence of developmental dysplasia of the hip
Correct answer: C
Rationale: The correct answer is C. Needing assistance to climb stairs is considered expected behavior for an 18-month-old toddler. At this age, children are still developing their gross motor skills, coordination, and balance, which can vary in proficiency. It is common for toddlers to be able to crawl upstairs before mastering the skill of climbing stairs upright. Options A, B, and D are incorrect because at 18 months, it is normal for children to require help and practice with climbing stairs and does not necessarily point to any specific medical conditions or developmental issues.
