Nursing Elites

1. The nurse is caring for a heart client on digoxin and notes a potassium level of 2.5. What is the appropriate priority nursing intervention?

• A. Do nothing as this is a normal potassium level.
• B. The potassium level is low so the nurse asks for an order for potassium.
• C. The nurse asks to check the digoxin level as low potassium can increase digoxin toxicity.
• D. The nurse stops the digoxin.

Correct answer: C

Rationale: The correct answer is C. When caring for a client on digoxin with a low potassium level, the priority nursing intervention is to check the digoxin level. Low potassium can increase the risk of digoxin toxicity. Checking the digoxin level will help determine if any adjustments to the medication regimen are needed to prevent potential harm. Choice A is incorrect as a potassium level of 2.5 is low, not normal. Choice B is not the priority as simply giving potassium may not address the underlying issue of potential digoxin toxicity. Choice D is not the initial action to take without assessing the digoxin level first.

2. The client asks about side effects of taking digoxin. How does the nurse respond?

• A. Anorexia can be a side effect of digoxin.
• B. Tachycardia can be a side effect of digoxin.
• C. Constipation can be a side effect of digoxin.
• D. Urinary retention can be a side effect of digoxin.

Correct answer: A

Rationale: The correct answer is A: 'Anorexia can be a side effect of digoxin.' Anorexia, nausea, vomiting, and diarrhea are commonly known side effects of digoxin. Choice B, 'Tachycardia can be a side effect of digoxin,' is incorrect as digoxin is used to treat tachycardia, not cause it. Choice C, 'Constipation can be a side effect of digoxin,' is incorrect as constipation is not a typical side effect of digoxin. Choice D, 'Urinary retention can be a side effect of digoxin,' is also incorrect as urinary retention is not a common side effect associated with digoxin use.

3. What is a chronic lung disease that includes chronic bronchitis and emphysema?

• A. Chronic Obstructive Pulmonary Disease (COPD)
• B. Pneumonia
• C. Asthma
• D. Tuberculosis

Correct answer: A

Rationale: The correct answer is Chronic Obstructive Pulmonary Disease (COPD). COPD is a chronic lung condition that encompasses chronic bronchitis and emphysema, causing airflow obstruction from the lungs. Pneumonia (choice B) is an infection in the lungs, while asthma (choice C) is characterized by airway inflammation and constriction. Tuberculosis (choice D) is a bacterial infection that primarily affects the lungs but is distinct from COPD.

4. What is a condition where the blood supply to part of the brain is interrupted or reduced, preventing brain tissue from getting oxygen and nutrients?

• A. Stroke
• B. Heart attack
• C. Pulmonary embolism
• D. Pneumonia

Correct answer: A

Rationale: A stroke occurs when the blood supply to part of the brain is interrupted or reduced, leading to brain cell death and potential disability. Choice B, a heart attack, involves a blockage in the blood vessels that supply the heart muscle. Choice C, a pulmonary embolism, is a blockage in one of the pulmonary arteries in the lungs. Choice D, pneumonia, is an infection that inflames the air sacs in one or both lungs.

5. What test uses sound waves to create pictures of the heart, allowing doctors to see how well the heart is functioning?

• A. Echocardiogram
• B. MRI
• C. CT scan
• D. X-ray

Correct answer: A

Rationale: The correct answer is an echocardiogram. This test utilizes sound waves to generate images of the heart, enabling doctors to evaluate both the function and structure of the heart. Choice B, MRI, uses magnetic fields and radio waves to produce detailed images of the body's organs and structures, not specifically focused on the heart. Choice C, CT scan, employs X-rays to create detailed cross-sectional images of the body, not primarily for the heart. Choice D, X-ray, uses electromagnetic radiation to produce images of internal structures, but it does not provide the detailed pictures of the heart's function that an echocardiogram does.
