ATI Pathophysiology Exam
1. Not realizing that its surface was hot, a woman has quickly withdrawn her hand from the surface of a bowl that she was removing from a microwave. Which phenomena has facilitated the rapid movement of her hand in response to the painful stimulus?
- A. Crossed-extensor reflex
- B. Flexor reflex
- C. Withdrawal reflex
- D. Stretch reflex
Correct answer: C
Rationale: The withdrawal reflex is a protective response that allows a person to quickly remove their hand from a painful stimulus.
2. A woman has been prescribed Climara, a transdermal estradiol patch. Which of the following should she be instructed by the nurse regarding the administration?
- A. Avoid prolonged sun exposure at the patch site due to increased plasma concentrations.
- B. The application of heat at the patch site will decrease effectiveness and result in pregnancy.
- C. The medication, when exposed to sunlight, can increase the risk of breast cancer.
- D. Exposure of the medication to occasional cold will increase effectiveness with application.
Correct answer: A
Rationale: The correct answer is A. The Climara patch delivers estradiol transdermally, and patients should be instructed to avoid prolonged sun exposure at the patch site due to increased plasma concentrations. Sun exposure can accelerate the absorption of the medication, leading to higher systemic levels than intended. Choices B, C, and D are incorrect because heat at the patch site does not result in pregnancy but may alter absorption rates, there is no direct link between sunlight exposure and breast cancer risk related to this medication, and exposure to cold does not increase effectiveness of the transdermal patch.
3. A male patient is receiving androgen therapy for the treatment of hypogonadism. What adverse effect should the nurse monitor for during this treatment?
- A. Liver dysfunction
- B. Kidney dysfunction
- C. Heart failure
- D. Pulmonary embolism
Correct answer: A
Rationale: The correct adverse effect to monitor for during androgen therapy for hypogonadism is liver dysfunction. Androgen therapy can lead to hepatotoxicity, so monitoring liver function tests is crucial during treatment. Kidney dysfunction (Choice B), heart failure (Choice C), and pulmonary embolism (Choice D) are not commonly associated with androgen therapy and are less likely adverse effects compared to liver dysfunction.
4. A client with a history of hypertension presents with a severe headache and blurred vision. What is the nurse's priority action?
- A. Administer pain relief medication.
- B. Obtain a stat head CT scan.
- C. Administer antihypertensive medications as prescribed.
- D. Call the healthcare provider immediately.
Correct answer: C
Rationale: The correct answer is to administer antihypertensive medications as prescribed. In a client with a history of hypertension presenting with severe headache and blurred vision, these symptoms could indicate a hypertensive crisis. The priority action is to lower the blood pressure promptly to prevent complications such as stroke, heart attack, or organ damage. Administering antihypertensive medications is crucial in this situation. Administering pain relief medication (Choice A) may temporarily alleviate symptoms but does not address the underlying issue of elevated blood pressure. Obtaining a stat head CT scan (Choice B) may be necessary to rule out other causes but should not delay the administration of antihypertensive medications. Calling the healthcare provider immediately (Choice D) is important but may not address the immediate need to lower blood pressure in a hypertensive crisis.
5. A patient has acute respiratory failure (ARF). Which of the following would the nurse expect to find?
- A. Alkalosis and hyperventilation
- B. Hypoxemia and hypercapnia
- C. Alkalosis and high potassium
- D. Elevated sodium and acidosis
Correct answer: B
Rationale: In acute respiratory failure, hypoxemia (low blood oxygen) and hypercapnia (high blood carbon dioxide) are commonly observed. Choice A is incorrect because alkalosis (high pH) and hyperventilation are not typically seen in acute respiratory failure. Choice C is incorrect as it mentions alkalosis and high potassium, which are not characteristic of acute respiratory failure. Choice D is also incorrect because elevated sodium and acidosis are not typically associated with acute respiratory failure.
