HESI LPN
Fundamentals HESI
1. Why should a client with an ileal conduit be instructed to empty the collection device frequently?
- A. Force urine to back up into the kidneys.
- B. Suppress production of urine.
- C. Cause the device to pull away from the skin.
- D. Tear the ileal conduit
Correct answer: C
Rationale: A full urine collection bag can cause the device to pull away from the skin, leading to potential leakage and skin irritation. Choice A is incorrect because a full urine collection bag does not force urine to back up into the kidneys. Choice B is incorrect as a full collection bag does not suppress the production of urine. Choice D is incorrect as a full collection bag is unlikely to tear the ileal conduit.
2. A client is being treated for diabetic ketoacidosis (DKA). Which laboratory value would be most concerning?
- A. Blood glucose of 350 mg/dL
- B. Serum bicarbonate of 18 mEq/L
- C. Arterial pH of 7.20
- D. Serum potassium of 5.5 mEq/L
Correct answer: C
Rationale: In a client with diabetic ketoacidosis (DKA), the most concerning laboratory value is an arterial pH of 7.20. An arterial pH of 7.20 indicates severe acidosis, which is a critical condition requiring immediate intervention. This pH level reflects a significant imbalance in the body's acid-base status, potentially leading to serious complications. High blood glucose levels (choice A) are expected in DKA but do not directly indicate the severity of acidosis. A serum bicarbonate level of 18 mEq/L (choice B) is low but not as immediately critical as a pH of 7.20. Serum potassium of 5.5 mEq/L (choice D) is elevated, which can occur in DKA due to insulin deficiency, but it is not the most concerning value in this scenario.
3. When children who are reared by adoptive parents are nonetheless more similar to their natural parents in a trait, it can be concluded that:
- A. the genetic characteristics of the children change over time.
- B. heredity is solely responsible for how a child grows.
- C. the environment is solely responsible for the development of those characteristics.
- D. genetics play a role in the development of those characteristics.
Correct answer: D
Rationale: When children exhibit traits that are more similar to their biological parents than their adoptive parents, it indicates a strong genetic influence on those traits. This similarity suggests that genetics play a significant role in the development of the observed characteristics. Choice A is incorrect because genetic characteristics do not change over time in this context. Choice B is incorrect as it implies that heredity is the only factor, disregarding the impact of the environment. Choice C is also incorrect as it suggests that only the environment influences trait development, overlooking the genetic contribution.
4. During an assessment, a client receiving tube feedings via NG tube shows signs of nasal mucosa irritation. What finding should the nurse report to the provider?
- A. Potassium 5.5 mEq/L
- B. Irritation of nasal mucosa
- C. Sodium 144 mEq/L
- D. Loose stools
Correct answer: B
Rationale: Irritation of nasal mucosa is a crucial finding that the nurse should report to the provider as it suggests potential complications with NG tube placement, such as improper positioning or mucosal damage. High potassium levels (Choice A) can be concerning but are not directly related to NG tube placement issues. Normal sodium levels (Choice C) and loose stools (Choice D) are common occurrences in clients receiving tube feedings and are not typically indicative of immediate complications that require urgent reporting.
5. How should a healthcare provider approach the care of a child with juvenile idiopathic arthritis (JIA)?
- A. Promote weight maintenance
- B. Encourage joint mobility exercises
- C. Avoid physical inactivity
- D. Ensure a balanced diet
Correct answer: B
Rationale: Encouraging joint mobility exercises is the appropriate approach to caring for a child with juvenile idiopathic arthritis (JIA). These exercises help maintain joint function and reduce stiffness, which are crucial in managing the condition. Choices A, C, and D are incorrect. Promoting weight maintenance is more relevant than weight gain as maintaining a healthy weight is important in managing JIA. Avoiding physical inactivity is not recommended as controlled and appropriate physical activities can help improve joint flexibility and overall health. Ensuring a balanced diet, which includes adequate protein, is important for overall nutrition but is not a specific intervention for managing JIA.
