Nursing Elites

1. The client is on spironolactone (Aldactone) and has a potassium level of 5.9 mEq/L. What is the nurse’s priority action?

• A. Hold the spironolactone and notify the healthcare provider.
• B. Administer potassium supplements.
• C. Continue the spironolactone as ordered.
• D. Increase the dose of spironolactone.

Correct answer: A

Rationale: The correct answer is A: Hold the spironolactone and notify the healthcare provider. A potassium level of 5.9 mEq/L is high, indicating hyperkalemia. Spironolactone is a potassium-sparing diuretic that can further increase potassium levels. Therefore, the priority action is to hold the medication to prevent exacerbating hyperkalemia and notify the healthcare provider for further guidance. Choice B is incorrect because administering potassium supplements would worsen hyperkalemia. Choice C is incorrect because continuing spironolactone could lead to a further increase in potassium levels. Choice D is incorrect because increasing the dose of spironolactone would exacerbate the hyperkalemia.

2. Which heart chamber receives oxygenated blood from the four pulmonary veins and serves as a reservoir during ventricular systole?

• A. Right atrium
• B. Left atrium
• C. Right ventricle
• D. Left ventricle

Correct answer: B

Rationale: The correct answer is B, Left atrium. The left atrium receives oxygenated blood from the lungs via the four pulmonary veins and acts as a holding chamber before the blood is pumped into the left ventricle. Choice A, Right atrium, is incorrect as it receives deoxygenated blood from the body via the vena cava. Choices C and D, Right ventricle and Left ventricle, are incorrect as they receive blood from the atria, not the pulmonary veins.

3. 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.

4. Which condition involves the body's immune system attacking the lungs and kidneys, causing severe respiratory and renal damage?

• A. Goodpasture syndrome
• B. Sarcoidosis
• C. Wegener's granulomatosis
• D. Interstitial lung disease

Correct answer: A

Rationale: Goodpasture syndrome is the correct answer. It is an autoimmune disease characterized by the immune system attacking the lungs and kidneys, leading to bleeding in the lungs and kidney failure. Sarcoidosis primarily affects the lungs and lymph nodes, not the kidneys. Wegener's granulomatosis affects the lungs, sinuses, and kidneys, but it is characterized by inflammation of blood vessels. Interstitial lung disease involves scarring of the lung tissue, not direct immune system attacks on the lungs and kidneys.

5. What procedure uses a catheter to open up a blocked or narrowed coronary artery, often involving the placement of a stent?

• A. Angioplasty
• B. Echocardiogram
• C. CT angiography
• D. Coronary artery bypass graft (CABG)

Correct answer: A

Rationale: The correct answer is Angioplasty. Angioplasty is a procedure that uses a catheter to open up a blocked or narrowed coronary artery, often involving the placement of a stent. Echocardiogram is a diagnostic test that uses sound waves to create images of the heart. CT angiography is a type of imaging test that looks at blood vessels, but it does not involve the placement of a stent. Coronary artery bypass graft (CABG) is a surgical procedure to improve blood flow to the heart muscle by bypassing blocked coronary arteries.
