HESI LPN
Adult Health 2 Exam 1
1. A client is prescribed warfarin (Coumadin) for atrial fibrillation. Which dietary instruction should the nurse provide?
- A. Increase intake of green leafy vegetables
- B. Avoid foods high in vitamin K
- C. Increase intake of foods rich in vitamin C
- D. Limit intake of dairy products
Correct answer: B
Rationale: The correct answer is B: 'Avoid foods high in vitamin K.' Vitamin K can decrease the effectiveness of warfarin, so it is essential for clients on warfarin therapy to avoid foods high in vitamin K. Green leafy vegetables are high in vitamin K, so choice A is incorrect. Choices C and D are unrelated to the dietary restrictions needed for clients taking warfarin and are therefore incorrect.
2. What should be used to feed an infant born with a unilateral cleft lip and palate?
- A. Plastic spoon
- B. Cross-cut nipple
- C. Parenteral infusion
- D. Rubber-tipped syringe
Correct answer: B
Rationale: A cross-cut nipple is the most appropriate choice for feeding an infant with a unilateral cleft lip and palate. Using a cross-cut nipple helps regulate the flow of milk, making feeding easier for the infant and reducing the risk of aspiration. Plastic spoons, parenteral infusion, and rubber-tipped syringes are not recommended for feeding infants with cleft lip and palate as they can pose risks such as choking, aspiration, or inadequate milk intake. It is essential to choose a feeding method that minimizes these risks and ensures proper nutrition for the infant.
3. What finding would lead the nurse to suspect that a child has Turner syndrome?
- A. Webbed neck
- B. Microcephaly
- C. Gynecomastia
- D. Cognitive delay
Correct answer: A
Rationale: A webbed neck is a key feature seen in Turner syndrome, a genetic condition that occurs in females due to a complete or partial absence of one of the X chromosomes. This physical trait is caused by excess skin on the neck, giving it a webbed appearance. Microcephaly (Choice B) is a condition characterized by a smaller than average head size and is not typically associated with Turner syndrome. Gynecomastia (Choice C) refers to breast enlargement in males and is not a common finding in Turner syndrome, which affects females. Cognitive delay (Choice D) is not a specific characteristic of Turner syndrome, as the syndrome primarily affects physical development and may not necessarily impact cognitive abilities.
4. A client is to receive 10 mEq of KCl diluted in 250 ml of normal saline over 4 hours. At what rate should the LPN/LVN set the client's intravenous infusion pump?
- A. 13 ml/hour
- B. 63 ml/hour
- C. 80 ml/hour
- D. 125 ml/hour
Correct answer: B
Rationale: To calculate the correct rate of infusion, divide the total volume by the total time: 250 ml / 4 hours = 62.5 ml/hour, which is rounded up to 63 ml/hour. This rate ensures the proper administration of the KCl over the 4-hour period. Choice A (13 ml/hour) is incorrect as it does not match the calculated rate. Choices C (80 ml/hour) and D (125 ml/hour) are also incorrect as they do not correspond to the calculated rate needed for the specified time frame.
5. What is an important consideration when caring for a child with epilepsy?
- A. Adherence to prescribed anticonvulsant medication
- B. Avoiding all forms of exercise
- C. Limiting social interactions
- D. Increasing dietary caffeine intake
Correct answer: A
Rationale: Adherence to prescribed anticonvulsant medication is crucial when caring for a child with epilepsy. It is essential for managing the condition effectively and reducing the frequency of seizures. Choice B is incorrect because exercise, when done safely and under supervision, can be beneficial for children with epilepsy by promoting overall health. Choice C is incorrect as social interactions are important for the child's emotional well-being and should not be limited. Choice D is incorrect as increasing dietary caffeine intake can potentially trigger seizures in some individuals with epilepsy.
