HESI PN Exit Exam 2024
1. What is the primary cause of diabetic ketoacidosis (DKA)?
- A. Insulin deficiency
- B. Overhydration
- C. Excess carbohydrate intake
- D. Excess insulin
Correct answer: A
Rationale: The correct answer is A: Insulin deficiency. Diabetic ketoacidosis occurs due to a severe lack of insulin, causing the body to break down fat for energy, leading to the production of ketones and acidification of the blood. Option B, Overhydration, is incorrect as DKA is characterized by dehydration rather than overhydration. Option C, Excess carbohydrate intake, is incorrect because while high blood sugar levels can contribute to DKA, the primary cause is insulin deficiency. Option D, Excess insulin, is also incorrect as DKA is not caused by an excess of insulin but rather by a lack of it.
2. What foods are appropriate for a 30-month-old toddler on a regular diet?
- A. Hamburger with bun and grapes
- B. Chicken fingers and french fries
- C. Hot dog with bun and potato chips
- D. Macaroni and cheese and Cheerios
Correct answer: D
Rationale: Macaroni and cheese and Cheerios are appropriate choices for a 30-month-old toddler on a regular diet as they provide a balance of carbohydrates and protein. Option A, hamburger with bun and grapes, may be difficult for a toddler to chew, and grapes pose a choking hazard. Option B, chicken fingers and french fries, are high in unhealthy fats and sodium. Option C, hot dog with bun and potato chips, are processed foods high in salt and unhealthy fats, not ideal for a toddler's diet.
3. A healthcare provider is assessing a child with suspected pneumonia. What clinical manifestation is the healthcare provider likely to observe?
- A. Cough
- B. Diarrhea
- C. Rash
- D. Vomiting
Correct answer: A
Rationale: When assessing a child with suspected pneumonia, a healthcare provider is likely to observe a cough as a common clinical manifestation. Pneumonia often presents with symptoms such as cough, fever, difficulty breathing, and chest pain. Choice B, diarrhea, is not typically associated with pneumonia. Choice C, rash, is not a common clinical manifestation of pneumonia. Choice D, vomiting, is also not a typical symptom of pneumonia. Therefore, the correct answer is A: Cough.
4. A client is prescribed metformin for the management of type 2 diabetes. What is the primary action of this medication?
- A. Stimulates insulin secretion from the pancreas.
- B. Increases insulin sensitivity in various tissues.
- C. Decreases hepatic glucose production.
- D. Delays absorption of glucose from the intestines.
Correct answer: C
Rationale: The correct answer is C: Decreases hepatic glucose production. Metformin primarily works by reducing the production of glucose in the liver (hepatic glucose production) and by improving insulin sensitivity in various tissues. Choice A is incorrect as metformin does not stimulate insulin secretion from the pancreas. Choice B is incorrect as metformin increases insulin sensitivity in various tissues, not just muscle cells. Choice D is incorrect as metformin does not delay glucose absorption from the intestines.
5. Which of the following new opportunities might a new nurse see in the future?
- A. Transitional care
- B. Traditional care
- C. Hospital-based care
- D. Care based on cost
Correct answer: A
Rationale: In the future, new nurses may see opportunities in transitional care. Transitional care involves the coordination and continuity of healthcare during a movement from one healthcare setting to another. This type of care is increasingly important in today's healthcare landscape due to the focus on improving patient outcomes and reducing hospital readmissions. Choices B, C, and D are incorrect as they do not represent emerging opportunities for new nurses in the future. Traditional care and hospital-based care are existing models of care delivery, while care based solely on cost does not align with the holistic approach to patient care that is becoming more prevalent in healthcare.
