ATI Pathophysiology Exam 3
1. Which of the following describes the condition in the body of clients experiencing hypovolemia?
- A. Increased urine retention
- B. Insufficient circulating blood volume
- C. Bounding peripheral pulses
- D. Crackles auscultated in the lungs
Correct answer: B
Rationale: The correct answer is B: Insufficient circulating blood volume. Hypovolemia is a condition characterized by a decrease in the volume of blood plasma. This reduction in circulating blood volume can lead to inadequate perfusion of tissues and organs, potentially resulting in shock if left untreated. Choices A, C, and D are incorrect because increased urine retention, bounding peripheral pulses, and crackles auscultated in the lungs are not typical manifestations of hypovolemia.
2. What is a characteristic of coronary artery disease (CAD)?
- A. The build-up of infectious by-products in the lymph nodes
- B. Insufficient delivery of oxygenated blood to the myocardium
- C. Insufficient delivery of carbon dioxide to the lungs
- D. The build-up of bile in the stomach and gallbladder
Correct answer: B
Rationale: The correct characteristic of coronary artery disease (CAD) is the insufficient delivery of oxygenated blood to the myocardium. CAD is a condition where the coronary arteries become narrowed or blocked, leading to reduced blood flow to the heart muscle. This lack of oxygenated blood can result in chest pain, known as angina, and if a coronary artery becomes completely blocked, it can cause a heart attack. Choices A, C, and D are incorrect. Choice A refers to an issue related to the lymphatic system, choice C is about gas exchange in the lungs, and choice D describes a problem with bile accumulation in the digestive system, none of which are characteristics of CAD.
3. What laboratory tests should the nurse monitor regularly when a male patient is receiving androgen therapy?
- A. Monitor liver function tests regularly.
- B. Monitor renal function tests regularly.
- C. Monitor blood glucose levels regularly.
- D. Monitor complete blood count (CBC) regularly.
Correct answer: A
Rationale: The correct answer is to monitor liver function tests regularly when a male patient is receiving androgen therapy. Androgen therapy can impact liver function, making it crucial to monitor liver function tests to assess any potential adverse effects on the liver. Renal function tests (choice B) are not typically affected by androgen therapy and do not need specific monitoring for this treatment. Blood glucose levels (choice C) are more relevant in conditions like diabetes or with medications affecting blood sugar, not typically in androgen therapy. Complete blood count (CBC) (choice D) is not directly impacted by androgen therapy and is not a priority for monitoring in this context.
4. A patient has developed a decubitus ulcer on the coccyx. What defense mechanism is most affected by this homeostatic change?
- A. The mucous membrane is affected.
- B. The respiratory tract is affected.
- C. The skin is affected.
- D. The gastrointestinal tract is affected.
Correct answer: C
Rationale: In this scenario, a decubitus ulcer on the coccyx indicates a breakdown of the skin's integrity due to prolonged pressure. The skin is the primary defense mechanism of the body against external pathogens. When the skin is compromised, it can lead to infections and other complications. The mucous membrane (Choice A) plays a role in protecting internal surfaces, not the skin. The respiratory tract (Choice B) is involved in breathing and not directly related to the skin's defense. The gastrointestinal tract (Choice D) is responsible for digestion and absorption of nutrients, not the primary defense mechanism against external threats like the skin.
5. A patient is starting on atorvastatin (Lipitor) for hyperlipidemia. What important instruction should the nurse provide?
- A. Take the medication at night to reduce the risk of muscle pain.
- B. Avoid consuming grapefruit juice while taking this medication.
- C. Take the medication in the morning with breakfast.
- D. Avoid taking the medication with alcohol to reduce the risk of liver damage.
Correct answer: A
Rationale: The correct answer is A. Atorvastatin should be taken at night to reduce the risk of muscle pain and other side effects. Taking it at night aligns with the body's natural rhythm of cholesterol production, optimizing its effectiveness. Choice B is incorrect because grapefruit juice can increase the risk of side effects by affecting the metabolism of atorvastatin. Choice C is incorrect as taking atorvastatin in the morning does not maximize its effectiveness. Choice D is incorrect because alcohol consumption can increase the risk of liver damage when combined with atorvastatin.
