What is a surgical procedure to redirect blood flow around a blocked or narrowed artery, often involving the use of a graft from another part of the body?
- A. Coronary artery bypass graft (CABG)
- B. Valve replacement
- C. Aneurysm repair
- D. Atherectomy
Correct Answer: A
Rationale: The correct answer is A: Coronary artery bypass graft (CABG). This procedure is used to redirect blood flow around a blocked or narrowed artery by creating a bypass using a graft from another part of the body. Step 1: The blocked or narrowed artery is identified through diagnostic tests. Step 2: A graft, often taken from the chest, leg, or arm, is used to create a new pathway for blood to flow around the blockage. Step 3: This helps improve blood flow to the heart muscle, relieving symptoms such as chest pain and reducing the risk of a heart attack. Summary: B (Valve replacement) involves replacing a damaged heart valve, C (Aneurysm repair) deals with treating a weakened area in a blood vessel, and D (Atherectomy) is a procedure to remove plaque from arteries, none of which match the description provided.
Which condition is characterized by fluid collection in the lungs, making it difficult to breathe?
- A. Pulmonary edema
- B. Pleurisy
- C. Pleural effusion
- D. Pneumothorax
Correct Answer: A
Rationale: Pulmonary edema is the correct answer because it is characterized by fluid accumulation in the lungs, leading to difficulty in breathing. This condition is often a result of heart failure, where the heart is unable to pump blood effectively, causing fluid to leak into the lungs. It can also be caused by lung infections or exposure to toxins.
Pleurisy (B) is inflammation of the pleura, the lining around the lungs, leading to chest pain exacerbated by breathing. Pleural effusion (C) is fluid accumulation in the pleural space around the lungs, not within the lungs themselves. Pneumothorax (D) is characterized by air accumulation in the pleural space, causing lung collapse, but not fluid collection in the lungs.
What is a condition characterized by an abnormal buildup of fluid between the layers of tissue lining the lungs and chest cavity?
- A. Pleural effusion
- B. Pulmonary edema
- C. Atelectasis
- D. Sarcoidosis
Correct Answer: A
Rationale: Pleural effusion is the correct answer because it specifically describes the abnormal buildup of fluid between the layers of tissue lining the lungs and chest cavity. This condition can cause symptoms like chest pain and difficulty breathing. Pulmonary edema, on the other hand, is the accumulation of fluid in the lung's air sacs, leading to breathing difficulties. Atelectasis refers to the collapse of a lung or a portion of it, not fluid buildup. Sarcoidosis is a disease that causes inflammation in various organs, not specifically fluid accumulation in the lungs. Therefore, pleural effusion best matches the described condition.
What type of stroke is caused by a blockage in an artery supplying blood to the brain?
- A. Ischemic stroke
- B. Hemorrhagic stroke
- C. Transient ischemic attack
- D. Embolism
Correct Answer: A
Rationale: The correct answer is A: Ischemic stroke. This type of stroke is caused by a blockage in an artery supplying blood to the brain, leading to a lack of oxygen and nutrients to brain cells. This blockage can be due to a blood clot or plaque buildup. Ischemic strokes account for the majority of stroke cases.
Incorrect choices:
B: Hemorrhagic stroke - This type of stroke occurs when a blood vessel in the brain ruptures, leading to bleeding in the brain.
C: Transient ischemic attack - Also known as a mini-stroke, it is caused by a temporary blockage of blood flow to the brain, often resolving on its own without permanent damage.
D: Embolism - This refers to a condition where a blood clot or other foreign material travels through the bloodstream and blocks a blood vessel in the brain.
Which of the following nursing interventions should a nurse perform when caring for a client with congestive heart failure who has decreased cardiac output?
- A. Encourage activities that engage the Valsalva maneuver.
- B. Encourage the client to perform exercises.
- C. Assess apical heart rate before administering digitalis.
- D. Offer small, frequent feedings.
Correct Answer: C
Rationale: Digitalis therapy requires careful monitoring of heart rate to prevent toxicity and worsening cardiac output.
