HESI LPN
HESI PN Nutrition Practice Exam
1. What is a common sign of iron-deficiency anemia in children?
- A. Yellowing of the skin
- B. Pallor and fatigue
- C. Rapid weight gain
- D. Increased appetite
Correct answer: B
Rationale: Pallor and fatigue are common signs of iron-deficiency anemia in children. Iron-deficiency anemia is characterized by a decreased production of red blood cells, leading to a paler appearance (pallor) and increased fatigue due to reduced oxygen-carrying capacity. Yellowing of the skin (choice A) is more commonly associated with liver or bile duct issues. Rapid weight gain (choice C) and increased appetite (choice D) are not typical signs of iron-deficiency anemia.
2. When preparing a teaching plan for a client who is to be discharged with a prescription for lithium carbonate (Lithonate), which instruction is most important for the nurse to include?
- A. It may take 3 to 4 weeks to achieve therapeutic effects.
- B. Keep your dietary salt intake consistent.
- C. Avoid eating aged cheese and chicken liver.
- D. Eat foods high in fiber such as whole grain breads.
Correct answer: B
Rationale: The correct answer is B: 'Keep your dietary salt intake consistent.' Consistent salt intake is crucial when taking lithium carbonate to avoid lithium toxicity or ineffectiveness due to its renal excretion mechanism. Option A is incorrect because it focuses on the time to achieve therapeutic effects, which is important but not as critical as maintaining consistent salt intake. Option C is incorrect as it mentions avoiding aged cheese and chicken liver, which is more relevant for individuals taking MAOIs. Option D is incorrect as it suggests eating high-fiber foods, which is not directly related to lithium carbonate therapy.
3. While turning and positioning a bedfast client, the PN observes that the client is dyspneic. Which action should the PN take first?
- A. Apply a pulse oximeter
- B. Measure blood pressure
- C. Notify the charge nurse
- D. Observe pressure areas
Correct answer: C
Rationale: Notifying the charge nurse promptly is the priority when a bedfast client is dyspneic. Dyspnea can indicate a serious problem that requires immediate assessment and intervention. Contacting the charge nurse ensures timely assistance and appropriate actions to address the client's condition. Applying a pulse oximeter or measuring blood pressure may provide valuable data, but the priority is prompt communication with the charge nurse to ensure quick intervention. Observing pressure areas, while important for overall client care, is not the most immediate action needed when a client is experiencing dyspnea.
4. A client with schizophrenia is prescribed risperidone. Which statement by the client indicates the need for further teaching?
- A. I can stop taking this medication once I feel better.
- B. This medication may cause drowsiness.
- C. This medication might make me feel drowsy.
- D. I should avoid alcohol while taking this medication.
Correct answer: A
Rationale: Clients should not stop taking risperidone abruptly once they feel better without consulting their healthcare provider.
5. A child with sickle cell anemia develops severe chest pain, fever, a cough, and dyspnea. What should the nurse do first?
- A. Administer 100% oxygen to relieve hypoxia
- B. Administer pain medication to relieve symptoms
- C. Notify the practitioner because chest syndrome is suspected
- D. Notify the practitioner because the child may be having a stroke
Correct answer: C
Rationale: The correct action to take first when a child with sickle cell anemia presents with severe chest pain, fever, cough, and dyspnea is to notify the practitioner because acute chest syndrome is suspected. This condition is a medical emergency requiring prompt intervention. Administering oxygen or pain medication may be necessary interventions but should not precede notifying the practitioner. Stroke is not typically associated with these symptoms in sickle cell anemia.
