Nursing Elites

1. A client with a history of angina is scheduled for an exercise electrocardiography (ECG) test. The nurse should explain that the purpose of this test is to evaluate which factor?

• A. The heart's response to physical stress
• B. The client's overall physical fitness
• C. The presence of electrolyte imbalances
• D. The effectiveness of anti-anginal medications

Correct answer: A

Rationale: An exercise electrocardiography (ECG) test is used to evaluate the heart's response to physical stress. During the test, the heart's electrical activity is monitored while the client exercises, helping to identify any areas of ischemia or abnormal rhythms. This test helps healthcare providers assess the heart's function and detect any potential issues related to angina or other cardiac conditions. Choice B, the client's overall physical fitness, is incorrect because the test primarily focuses on the heart's response to stress rather than the client's general physical fitness. Choice C, the presence of electrolyte imbalances, is incorrect as this test is not specifically designed to evaluate electrolyte levels. Choice D, the effectiveness of anti-anginal medications, is incorrect as the main purpose of the test is to assess the heart's response to physical stress, not medication effectiveness.

2. The nurse is teaching a client about lifestyle changes to manage hypertension. Which dietary change should the nurse recommend?

• A. Increase intake of red meat
• B. Use salt substitutes liberally
• C. Limit sodium intake to 2 grams per day
• D. Increase intake of processed foods

Correct answer: C

Rationale: The correct answer is C: 'Limit sodium intake to 2 grams per day.' This recommendation is crucial in managing hypertension because excessive sodium intake can lead to elevated blood pressure. Reducing sodium intake helps the body regulate fluid balance and lower blood pressure. Choices A, B, and D are incorrect. Increasing red meat intake can worsen hypertension due to its high saturated fat content. Using salt substitutes liberally can also be harmful as they often contain high amounts of potassium, which can be problematic for individuals with certain health conditions. Increasing processed foods consumption is generally discouraged in hypertension management due to their high sodium content and low nutritional value.

3. A client is receiving heparin therapy. Which of the following laboratory tests should be monitored to evaluate the effectiveness of the therapy?

• A. Prothrombin time (PT)
• B. International normalized ratio (INR)
• C. Activated partial thromboplastin time (aPTT)
• D. Complete blood count (CBC)

Correct answer: C

Rationale: Activated partial thromboplastin time (aPTT) is the most appropriate laboratory test to monitor the effectiveness of heparin therapy. Heparin works on the intrinsic pathway of the coagulation cascade, and monitoring aPTT helps assess its anticoagulant effect. Therapeutic levels of aPTT for clients on heparin therapy are typically 1.5 to 2.5 times the control value. Prothrombin time (PT) and International normalized ratio (INR) are used to monitor warfarin therapy, which acts on the extrinsic pathway of the coagulation cascade. Complete blood count (CBC) is not specific for monitoring the effectiveness of heparin therapy.

4. A healthcare professional is assessing a client who has been taking isoniazid to treat tuberculosis. The healthcare professional should monitor the client for which of the following findings as an adverse effect of the medication?

• A. Diarrhea
• B. Blurred vision
• C. Hearing loss
• D. Jaundice

Correct answer: D

Rationale: Correct. Jaundice is a serious adverse effect of isoniazid due to liver damage. It is essential to monitor for signs of liver toxicity, such as jaundice, while the client is on this medication. Diarrhea is a common side effect of isoniazid, but it is not as serious as liver damage. Blurred vision and hearing loss are not typically associated with isoniazid use.

5. Which statement indicates that a client with coronary artery disease (CAD) understands disease management?

• A. I will walk for one-half hour daily.
• B. As long as I exercise, I can eat anything I wish.
• C. My weight plays no role in this disease.
• D. My father's high cholesterol is irrelevant.

Correct answer: A

Rationale: Choice A is the correct answer because regular physical activity, such as walking for half an hour daily, is beneficial for managing coronary artery disease (CAD) and promoting heart health. Walking helps improve circulation, reduce cholesterol levels, and maintain a healthy weight, all of which are crucial for managing CAD. Choice B is incorrect because diet also plays a significant role in CAD management, not just exercise. Choice C is incorrect because weight management is essential in controlling CAD risk factors. Choice D is incorrect because family history of high cholesterol can increase the risk of CAD, making it relevant for disease management.
