HESI LPN
Community Health HESI Practice Exam
1. A client with a history of alcoholism is admitted to the hospital for detoxification. The nurse knows that the client's risk for withdrawal symptoms is greatest within:
- A. 2-4 hours
- B. 4-6 hours
- C. 6-12 hours
- D. 12-24 hours
Correct answer: D
Rationale: The correct answer is D: 12-24 hours. Withdrawal symptoms typically begin within 12-24 hours after the last drink. This period is when the client is at the highest risk for experiencing withdrawal symptoms. Choices A, B, and C are incorrect because they do not align with the typical timeline for alcohol withdrawal symptoms to manifest. Symptoms usually peak within the first 24 to 48 hours after the last drink, making the 12-24 hour window critical for monitoring and managing any potential withdrawal complications.
2. A client arrives at the emergency department experiencing diabetic ketoacidosis (DKA). The healthcare provider prescribes an insulin intravenous drip. Which type of insulin should the nurse locate for the registered nurse to mix into the intravenous fluids?
- A. Isophane
- B. Glargine
- C. Regular
- D. Detemir
Correct answer: C
Rationale: The correct insulin type for the nurse to mix into the intravenous fluids is regular insulin. In the scenario of diabetic ketoacidosis (DKA), rapid reduction of blood glucose levels is crucial. Regular insulin has a fast onset of action, making it suitable for intravenous administration to address the high blood sugar levels seen in DKA. Isophane, Glargine, and Detemir are not appropriate choices for intravenous administration in this emergency situation as they are intermediate-acting or long-acting insulins which do not provide the rapid response needed in DKA.
3. Before meiosis, a sperm cell:
- A. contains 46 chromosomes.
- B. contains two X chromosomes.
- C. is significantly larger than an egg cell.
- D. contains both an X and a Y chromosome.
Correct answer: A
Rationale: Before meiosis, a sperm cell contains 46 chromosomes. This is because sperm cells, like other somatic cells, have a diploid number of chromosomes. During meiosis, the number of chromosomes is halved to 23 to combine with an egg cell during fertilization. Choice B is incorrect because a sperm cell carries either an X or a Y chromosome, not both (Choice D). Choice C is incorrect as sperm cells are generally smaller than egg cells, which is an adaptation that aids in motility and penetration of the egg during fertilization.
4. In planning care for a 7-year-old boy with diabetes insipidus, what is the priority nursing diagnosis?
- A. Deficient fluid volume related to dehydration
- B. Excess fluid volume related to edema
- C. Deficient knowledge related to fluid intake regimen
- D. Imbalanced nutrition, more than body requirements related to excess weight
Correct answer: A
Rationale: The priority nursing diagnosis for a 7-year-old boy with diabetes insipidus is deficient fluid volume related to dehydration. Diabetes insipidus leads to excessive urination and fluid loss, which can result in dehydration. This diagnosis should take precedence as restoring fluid balance is crucial in managing this condition. Choices B, C, and D are less of a priority in this case. Excess fluid volume related to edema is not typically associated with diabetes insipidus. Deficient knowledge about fluid intake and imbalanced nutrition related to excess weight may be important but addressing the dehydration and fluid volume deficit is the most critical aspect in the immediate care of a child with diabetes insipidus.
5. When developing the plan of care for a child with cerebral palsy, which treatment would the nurse expect as least likely?
- A. Skeletal traction
- B. Physical therapy
- C. Orthotics
- D. Occupational therapy
Correct answer: A
Rationale: When caring for a child with cerebral palsy, skeletal traction is the least likely treatment intervention. Cerebral palsy primarily involves motor function impairments, and skeletal traction is not a typical intervention for this condition. Physical therapy is commonly used to improve movement and function, orthotics help with posture and mobility, and occupational therapy addresses activities of daily living. These interventions are more aligned with the needs of a child with cerebral palsy compared to skeletal traction, making it the least likely treatment option.
