This is a type of therapy that involves removing fluid from the lungs, typically through the use of diuretics.
- A. Diuretic therapy
- B. Oxygen therapy
- C. Inhaler therapy
- D. Antihistamine therapy
Correct Answer: A
Rationale: The correct answer is A: Diuretic therapy. This is because diuretics are medications used to remove excess fluid from the body, including the lungs. By increasing urine output, diuretics help reduce fluid buildup in the lungs, making it easier to breathe. Oxygen therapy (B) delivers oxygen to the lungs but does not involve removing fluid. Inhaler therapy (C) is used for respiratory conditions like asthma but does not remove fluid from the lungs. Antihistamine therapy (D) is used to treat allergies and does not address fluid buildup in the lungs. Thus, diuretic therapy is the most appropriate choice for removing fluid from the lungs.

What is the term for the amount of blood ejected by the left ventricle into the aorta per beat, determined by preload, contractility, and afterload?
- A. Stroke volume
- B. Cardiac output
- C. End-diastolic volume
- D. Ejection fraction
Correct Answer: A
Rationale: The correct answer is A: Stroke volume. Stroke volume is the amount of blood ejected by the left ventricle into the aorta per beat. Preload (end-diastolic volume), contractility, and afterload influence stroke volume. Cardiac output (B) is the total volume of blood pumped by the heart per minute. End-diastolic volume (C) is the volume of blood in the ventricle before contraction. Ejection fraction (D) is the percentage of blood ejected from the ventricle during systole.
Which of the following is a chronic condition characterized by difficulty breathing due to airflow obstruction, commonly associated with long-term smoking?
- A. Chronic obstructive pulmonary disease (COPD)
- B. Asthma
- C. Pulmonary hypertension
- D. Bronchitis
Correct Answer: A
Rationale: Rationale:
1. Chronic obstructive pulmonary disease (COPD) is characterized by airflow obstruction and difficulty breathing.
2. COPD is commonly linked to long-term smoking due to the damage caused to the lungs.
3. Asthma involves airway inflammation and reversible airflow obstruction, not necessarily linked to smoking.
4. Pulmonary hypertension is high blood pressure in the lungs, not directly related to smoking.
5. Bronchitis is inflammation of the bronchial tubes, not synonymous with airflow obstruction.
Summary: COPD is the correct answer as it aligns with the chronic condition characterized by airflow obstruction due to long-term smoking, distinguishing it from the other choices.
What is a condition where the heart is unable to relax properly between beats, reducing its ability to fill with blood?
- A. Diastolic heart failure
- B. Systolic heart failure
- C. Hypertrophic cardiomyopathy
- D. Restrictive cardiomyopathy
Correct Answer: A
Rationale: The correct answer is A: Diastolic heart failure. In diastolic heart failure, the heart is unable to relax properly during the filling phase (diastole), leading to impaired filling of the ventricles. This results in decreased blood supply to the body. Systolic heart failure, on the other hand, is characterized by the heart's inability to contract effectively during the ejection phase (systole). Hypertrophic cardiomyopathy involves abnormal thickening of the heart muscle, affecting its function. Restrictive cardiomyopathy is characterized by stiffening of the heart muscle, impairing its ability to relax and fill properly, but it is different from diastolic heart failure.
Which valve prevents backflow of blood into the left ventricle from the aorta?
- A. Aortic valve
- B. Mitral valve
- C. Tricuspid valve
- D. Pulmonary valve
Correct Answer: A
Rationale: The correct answer is A: Aortic valve. The aortic valve is located between the left ventricle and the aorta, preventing the backflow of blood into the left ventricle during diastole. This is essential for maintaining proper blood flow direction and preventing regurgitation. The other choices, B: Mitral valve, C: Tricuspid valve, and D: Pulmonary valve, are all located in different areas of the heart and serve different functions. The mitral valve is between the left atrium and ventricle, the tricuspid valve is between the right atrium and ventricle, and the pulmonary valve is between the right ventricle and pulmonary artery. None of these valves are responsible for preventing backflow into the left ventricle from the aorta.
The client on nitroglycerin patches reports dizziness when standing up. What is the nurse's best response?
- A. Advise the client to rise slowly to prevent dizziness.
- B. Instruct the client to discontinue the nitroglycerin patches.
- C. Encourage the client to rest and avoid physical activity.
- D. Suggest the client take an over-the-counter antiemetic.
Correct Answer: A
Rationale: The correct response is A: Advise the client to rise slowly to prevent dizziness. Nitroglycerin patches can cause orthostatic hypotension, leading to dizziness when standing up quickly. By advising the client to rise slowly, the nurse can help prevent a sudden drop in blood pressure and reduce the risk of dizziness and falls. This response promotes client safety and addresses the underlying cause of the symptom.
Choices B, C, and D are incorrect:
B: Instructing the client to discontinue nitroglycerin patches is not appropriate without consulting the healthcare provider. Abruptly stopping nitroglycerin can lead to serious complications.
C: Encouraging the client to rest and avoid physical activity does not address the issue of orthostatic hypotension caused by nitroglycerin patches.
D: Suggesting an over-the-counter antiemetic is not indicated for dizziness related to orthostatic hypotension. It does not address the underlying cause
