ATI Pathophysiology Exam 2

1. Which of the following describes the pathophysiology of exercise-induced asthma?

Correct answer: A

Rationale: The correct answer is A: 'Bronchospasm after exercise.' Exercise-induced asthma involves the narrowing of the airways (bronchospasm) triggered by physical activity. This bronchospasm leads to symptoms such as coughing, wheezing, and shortness of breath. Choices B, C, and D are incorrect because exercise-induced asthma is not primarily caused by an IgE-mediated inflammatory response to an antigen, bronchoconstriction after ingesting high-allergen foods, or increased mucus production due to a genetic mutation.

2. A nurse practitioner is assessing a 7-year-old boy who has been brought to the clinic by his mother, who is concerned about her son's increasingly frequent, severe headaches. Which of the nurse's questions is least likely to yield data that will confirm or rule out migraines as the cause of his problem?

Correct answer: C

Rationale: The correct answer is C. In assessing a child for migraines, asking about food allergies is least likely to yield data that will confirm or rule out migraines as the cause of his headaches. Food allergies are unrelated to the typical symptoms and triggers of migraines, such as family history, associated symptoms like nausea and vomiting, and pain-free intervals between headaches. Therefore, in this scenario, focusing on food allergies is less relevant for identifying migraines as the cause of the boy's headaches.

3. A female patient is taking combined hormonal contraceptives to prevent pregnancy. She visits the gynecology clinic and is noted to have a blood pressure of 176/102 mm Hg. The patient is started on enalapril mesylate 10 mg. In collaboration with the primary care provider, what other patient teaching should be provided based on her current medication regimen?

Correct answer: A

Rationale: Women on hormonal contraceptives and antihypertensives like enalapril should be counseled to adopt a low-salt diet if severe hypertension occurs. This dietary modification can help in managing blood pressure levels. Instructing to discontinue the contraceptives is crucial in cases of severe hypertension as it poses an increased risk of cardiovascular events. Instructing on relaxation techniques may have some benefits in reducing stress levels but addressing the root cause, such as discontinuing contraceptives in this scenario, is more critical. There is no rationale for increasing the contraceptive dose when hypertension is present; in fact, it should be stopped to prevent complications.

4. A patient is taking a statin for hyperlipidemia. What important instruction should the nurse provide to the patient?

Correct answer: A

Rationale: The correct answer is to instruct the patient to take the medication at night to avoid muscle pain. Statins are known to potentially cause muscle pain or weakness; taking the medication at night can help reduce the incidence of these side effects. Option B is incorrect because the timing of statin administration is not related to its effectiveness throughout the day. Option C is a general precaution when taking medications but not the most important instruction specific to statins. Option D is incorrect as taking the medication with a high-fat meal can actually decrease its absorption.

5. A client has approached the nurse asking for advice on how to deal with his alcohol addiction. The nurse should tell the client that the only effective treatment for alcoholism is:

Correct answer: B

Rationale: The correct answer is B: total abstinence. Total abstinence from alcohol is considered the most effective treatment for alcoholism. This approach eliminates the risk of relapse and helps individuals maintain sobriety. While psychotherapy can be beneficial in addressing underlying issues, total abstinence is crucial in overcoming alcohol addiction. Alcoholics Anonymous (AA) is a supportive group that can complement treatment, but it is not the only effective approach. Aversion therapy aims to create a negative association with alcohol but may not address the underlying causes of addiction, making total abstinence a more comprehensive and recommended approach.
