ATI Pathophysiology Exam 2
1. Which of the following accurately describes the pathophysiology of asthma?
- A. Chronic inflammation of the bronchial lining
- B. Narrowing of the airway due to bronchoconstriction
- C. Damage to alveoli reducing lung elasticity
- D. Overproduction of mucus by the goblet cells
Correct answer: B
Rationale: The correct answer is B: "Narrowing of the airway due to bronchoconstriction." In asthma, there is an inflammatory response that leads to bronchoconstriction, causing the airways to narrow and making it difficult to breathe. Choice A is incorrect as chronic inflammation is a feature of asthma but not the primary pathophysiological mechanism. Choice C is incorrect as damage to alveoli is more characteristic of conditions like emphysema. Choice D is incorrect as overproduction of mucus is a feature of chronic bronchitis, not asthma.
2. Which of the following statements about medications is true?
- A. Over-the-counter medications are unlikely to interact with food or nutrients
- B. Prescription medications always have significant interactions with food
- C. Prescription and nonprescription drugs and herbal remedies interact with food
- D. Herbal products are generally safe since they are natural
Correct answer: C
Rationale: The correct answer is C. This statement is true because both prescription medications and over-the-counter medications, along with herbal remedies, can interact with food. Choice A is incorrect because over-the-counter medications can also interact with food or nutrients. Choice B is incorrect as not all prescription medications have significant interactions with food. Choice D is misleading because herbal products are not always safe, as they can have side effects and interact with other medications.
3. A 65-year-old male patient was admitted to a medical-surgical unit 72 hours ago with pyloric stenosis; a nasogastric tube was inserted upon admission and has been on low intermittent suction since then. The nurse taking care of the patient notices that his potassium is very low and becomes concerned that the patient may be at risk for:
- A. Hypercalcemia
- B. Metabolic acidosis
- C. Metabolic alkalosis
- D. Respiratory acidosis
Correct answer: C
Rationale: The correct answer is C, metabolic alkalosis. The patient with pyloric stenosis has been on low intermittent suction, leading to the loss of hydrogen and chloride ions. This condition causes metabolic alkalosis due to the removal of these ions. Options A (Hypercalcemia) and D (Respiratory acidosis) are incorrect as they are not directly related to the scenario described. Option B (Metabolic acidosis) is also incorrect; in this case, the patient is at risk of metabolic alkalosis due to the loss of hydrogen and chloride ions through gastric suction.
4. A nurse is teaching a client who has a new prescription for iron supplements. Which of the following statements by the client indicates an understanding of the teaching?
- A. I should take this medication with a glass of milk.
- B. I will take this medication with orange juice.
- C. I should expect my stools to be black and tarry.
- D. I will take this medication before bedtime.
Correct answer: C
Rationale: The correct answer is C. When a client understands the teaching about iron supplements, they should know that black, tarry stools are a normal side effect. This indicates that the medication is being absorbed and working effectively. Choices A and B are incorrect because iron supplements should not be taken with milk or orange juice, as these can interfere with the absorption of iron. Choice D is also incorrect because iron supplements are usually best absorbed on an empty stomach, so taking them before bedtime may not be ideal.
5. Maggie, a child in protective custody, is found to have an imaginary friend, Holly. Her foster family shares this information with the nurse. The nurse teaches the family members about children who have suffered trauma and knows her teaching was effective when the foster mother states:
- A. I understand that imaginary friends are abnormal.
- B. I understand that imaginary friends are a maladaptive behavior.
- C. I understand that imaginary friends are a coping mechanism.
- D. I understand that we should tell the child that imaginary friends are unacceptable.
Correct answer: C
Rationale: Imaginary friends can serve as a coping mechanism for children, especially those who have experienced trauma. They can provide comfort and a sense of control in challenging situations. Acknowledging and supporting the child's imaginary friend can be beneficial in their emotional healing and development.
