ATI Pathophysiology Exam 1
1. What causes type I diabetes?
- A. Overproduction of insulin from the beta cells of the pancreas
- B. Destruction of the beta cells within the pancreas, resulting in an inability to produce insulin
- C. Loss of insulin receptors on the target cells, resulting in insulin resistance
- D. A pituitary tumor in the brain, resulting in increased antidiuretic hormone production
Correct answer: B
Rationale: Type I diabetes is caused by the destruction of the beta cells in the pancreas, leading to an inability to produce insulin. This results in a lack of insulin, leading to hyperglycemia. Choice A is incorrect as type I diabetes is characterized by a deficiency of insulin production, not overproduction. Choice C describes the pathophysiology of type 2 diabetes, where insulin receptors become less responsive to insulin. Choice D is unrelated to type I diabetes as it describes a pituitary tumor causing increased antidiuretic hormone production.
2. A nurse is caring for a client who has a chest tube following thoracic surgery. Which of the following actions should the nurse take?
- A. Clamp the chest tube when assisting the client out of bed.
- B. Empty the drainage system every 8 hours.
- C. Keep the collection device below the client's chest.
- D. Strip the chest tube every 4 hours.
Correct answer: C
Rationale: The correct action for the nurse to take is to keep the collection device below the client's chest. This positioning ensures proper drainage of fluid from the chest, preventing backflow of fluids. Clamping the chest tube when assisting the client out of bed is incorrect as it can lead to fluid accumulation and potential complications. Emptying the drainage system every 8 hours is necessary but not the priority over maintaining proper positioning. Stripping the chest tube every 4 hours is an outdated practice and can cause damage to the tissue and should be avoided.
3. A client has a new prescription for Digoxin to treat heart failure. Which of the following findings should the nurse monitor as an adverse effect?
- A. Visual disturbances
- B. Dry cough
- C. Confusion
- D. Urinary retention
Correct answer: A
Rationale: Visual disturbances, such as blurred or yellow vision, can be an early sign of digoxin toxicity. Monitoring for visual changes is crucial to detect and prevent potential adverse effects of digoxin. Dry cough, confusion, and urinary retention are not commonly associated adverse effects of digoxin and are not typically monitored in relation to this medication.
4. At an 8-month-old well-baby visit, the parent tells the nurse that her infant falls asleep at night during the last bottle feeding but wakes up when moved to the infant’s crib. What is the most appropriate response for the nurse to make?
- A. You should put your baby to sleep 1 hour earlier without the nighttime feeding but with a pacifier for soothing.
- B. You could place rice cereal in the last bottle feeding of the day to ensure a longer sleep pattern.
- C. You should have your partner give the last bottle of the day and observe whether your infant stays awake for your partner.
- D. You could increase daytime feeding intervals to every 4 hours and put your baby in the crib while the baby is still awake.
Correct answer: D
Rationale: Encouraging the baby to fall asleep in the crib while still awake can help establish healthy sleep habits and reduce night waking.
5. Which of the following is considered voluntary turnover?
- A. Desire to leave
- B. Termination
- C. Forced resignation
- D. Floating
Correct answer: A
Rationale: The correct answer is A, 'Desire to leave.' Voluntary turnover occurs when an employee chooses to leave the organization. In this case, it is a direct function of the nurse's desire to leave. Termination and forced resignation are involuntary processes where the decision is made by the employer, not the employee. 'Floating' refers to the reassignment of a nurse to a unit different from their usual work unit and is not directly related to turnover.
