1. What is an acute respiratory infection that inflames the alveoli in one or both lungs, causing them to fill with fluid or pus?

• A. Pneumonia
• B. Bronchitis
• C. Tuberculosis
• D. Asthma

Correct answer: A

Rationale: Pneumonia is the correct answer because it is an acute respiratory infection that inflames the alveoli in one or both lungs, leading to the accumulation of fluid or pus. This condition presents with symptoms like cough, fever, and difficulty breathing. Bronchitis is the inflammation of the bronchial tubes, not the alveoli. Tuberculosis is a bacterial infection that primarily affects the lungs but does not always result in alveolar inflammation. Asthma is a chronic respiratory condition characterized by airway inflammation and narrowing, not alveolar inflammation.

2. Which type of medication is used to reduce the workload on the heart by slowing down the heart rate and lowering blood pressure?

• A. Beta-blocker
• B. ACE inhibitor
• C. Calcium channel blocker
• D. Diuretic

Correct answer: A

Rationale: The correct answer is A: Beta-blocker. Beta-blockers are medications that reduce the workload on the heart by slowing down the heart rate and lowering blood pressure. They are commonly used in the treatment of heart conditions such as hypertension and heart failure. ACE inhibitors (B) work by dilating blood vessels to reduce blood pressure, calcium channel blockers (C) prevent calcium from entering the heart muscle and blood vessel walls, and diuretics (D) help the body get rid of excess salt and water by increasing urine production.

3. Which valves close during ventricular systole and open during ventricular diastole?

• A. Semilunar valves
• B. Atrioventricular Valves
• C. Mitral valve
• D. Tricuspid valve

Correct answer: B

Rationale: The correct answer is B: Atrioventricular Valves. The atrioventricular (AV) valves, including the mitral valve and tricuspid valve, close during ventricular systole to prevent backflow of blood from the ventricles into the atria. They open during ventricular diastole to allow blood flow from the atria into the ventricles. Semilunar valves, choice A, are located at the exits of the ventricles and prevent backflow into the ventricles. The mitral valve and tricuspid valve, choices C and D, are specific types of AV valves.

4. The client is on a nitrate for angina. What is the most common side effect the nurse should monitor for?

• A. Headache
• B. Flushing
• C. Dizziness
• D. Nausea

Correct answer: A

Rationale: The correct answer is A, Headache. Nitrates commonly cause headaches as a side effect due to vasodilation. Flushing, dizziness, and nausea are less common side effects associated with nitrates. Flushing is more related to the dilation of blood vessels closer to the skin's surface, dizziness could occur but is not as common as headaches, and nausea is a less typical side effect of nitrates.

5. What is a chronic condition where the heart muscle becomes weakened and enlarged, reducing its ability to pump blood effectively?

• A. Dilated cardiomyopathy
• B. Hypertrophic cardiomyopathy
• C. Myocarditis
• D. Pericarditis

Correct answer: A

Rationale: Dilated cardiomyopathy is characterized by the weakening and enlargement of the heart muscle, leading to its reduced ability to pump blood effectively. This condition is different from hypertrophic cardiomyopathy, which involves abnormal thickening of the heart muscle, myocarditis, which is inflammation of the heart muscle, and pericarditis, which is inflammation of the pericardium. Therefore, the correct answer is Dilated cardiomyopathy.
