Nursing Elites

1. The client is prescribed warfarin. What should the client be taught about this medication?

• A. Avoid foods high in vitamin K.
• B. Take the medication with food to prevent stomach upset.
• C. Take the medication at the same time every day.
• D. Increase the dose if a dose is missed.

Correct answer: A

Rationale: The correct answer is A: Avoid foods high in vitamin K. Warfarin is an anticoagulant medication, and vitamin K can counteract its effects. Therefore, it is important for clients taking warfarin to avoid foods high in vitamin K to maintain the medication's effectiveness. Choice B is incorrect because warfarin should be taken consistently as prescribed, regardless of food intake. Choice C is incorrect because while consistency in timing is important, it is not specific to the effectiveness of warfarin. Choice D is incorrect because clients should never increase the dose of warfarin on their own, especially to make up for a missed dose, as it can lead to serious bleeding risks.

2. This test measures the amount of blood the heart pumps with each beat, often used to assess heart function.

• A. Ejection fraction
• B. Cardiac output
• C. Stroke volume
• D. End-diastolic volume

Correct answer: A

Rationale: The correct answer is A: Ejection fraction. Ejection fraction is a measure of the percentage of blood that is pumped out of the left ventricle with each beat, used to assess heart function. Choice B, Cardiac output, is the total volume of blood pumped by the heart per minute and is not specific to each beat. Choice C, Stroke volume, is the amount of blood ejected by the heart in one contraction but does not specify the percentage of blood pumped out. Choice D, End-diastolic volume, is the volume of blood in the ventricle just before it contracts and does not directly measure the blood pumped with each beat.

3. Which of the following is a type of heart attack that occurs when the blood supply to part of the heart muscle is severely reduced or stopped?

• A. Myocardial infarction
• B. Angina
• C. Stroke
• D. Congestive heart failure

Correct answer: A

Rationale: The correct answer is A: Myocardial infarction. Myocardial infarction, commonly known as a heart attack, occurs when the blood supply to part of the heart muscle is severely reduced or stopped, leading to tissue damage or death. Angina (choice B) is chest pain or discomfort that occurs when the heart muscle doesn't get enough oxygen-rich blood. Stroke (choice C) is a condition where the blood supply to the brain is interrupted or reduced. Congestive heart failure (choice D) is a chronic condition where the heart muscle doesn't pump blood as well as it should.

4. The nurse is caring for a client with atrial fibrillation on dabigatran (Pradaxa). What is the most important instruction to give to the client?

• A. Take the medication with food to prevent stomach upset.
• B. Do not miss a dose and take it at the same time each day.
• C. Avoid consuming alcohol while on this medication.
• D. Monitor for signs of bleeding.

Correct answer: B

Rationale: The most important instruction to give to a client on dabigatran (Pradaxa) is not to miss a dose and take it at the same time each day. This is crucial for maintaining the anticoagulant effect of the medication. Choice A is not necessary as dabigatran does not need to be taken with food. Choice C is important but not as crucial as ensuring proper dosing. Choice D is also important but falls behind in priority compared to maintaining consistent dosing.

5. What is the condition where the lung collapses due to air leaking into the space between the lung and chest wall?

• A. Pneumothorax
• B. Pleural effusion
• C. Pulmonary fibrosis
• D. Lung cancer

Correct answer: A

Rationale: Pneumothorax is the correct answer. It is the collapse of a lung due to air leaking into the space between the lung and chest wall. This condition often requires emergency treatment. Choice B, Pleural effusion, is the buildup of excess fluid between the layers of the pleura outside the lung, not air. Choice C, Pulmonary fibrosis, is a lung disease characterized by scarring and thickening of lung tissue, not related to lung collapse. Choice D, Lung cancer, is the uncontrolled growth of abnormal cells in the lung, not directly causing lung collapse.
