Nokea
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.

While obtaining patient histories, which patient does the nurse identify as having the highest risk for CAD?
- A. A white man, age 54, who is a smoker and has a stressful lifestyle
- B. A white woman, age 68, with a BP of 172/100 mm Hg and who is physically inactive
- C. An Asian woman, age 45, with a cholesterol level of 240 mg/dL and a BP of 130/74 mm Hg
- D. An obese African American man, age 65, with a cholesterol level of 195 mg/dL and a BP of 128/76 mm Hg
Correct Answer: A
Rationale: Smoking and stress are strong risk factors for CAD.
What is the procedure where a catheter is used to open a blocked or narrowed coronary artery, often involving the placement of a stent?
- A. Angioplasty
- B. Valve replacement
- C. Stent placement
- D. Coronary artery bypass graft (CABG)
Correct Answer: A
Rationale: The correct answer is A: Angioplasty. During angioplasty, a catheter with a balloon at its tip is used to open a blocked or narrowed coronary artery. The balloon is inflated to widen the artery and improve blood flow. Often, a stent is placed during the procedure to help keep the artery open. Option B, valve replacement, is incorrect as it involves replacing a faulty heart valve, not opening a blocked coronary artery. Option C, stent placement, is close but not specific to the procedure of using a catheter and balloon. Option D, CABG, is a surgical procedure where arteries or veins are used to bypass blocked coronary arteries, not using a catheter.
The nurse is administering nitroglycerin IV to a client with chest pain. What is the most important parameter to monitor?
- A. Blood pressure
- B. Heart rate
- C. Oxygen saturation
- D. Respiratory rate
Correct Answer: A
Rationale: The correct answer is A: Blood pressure. When administering nitroglycerin IV for chest pain, monitoring blood pressure is crucial as it can drop significantly, leading to hypotension. This can cause further complications. Heart rate may increase initially due to vasodilation, but it's not the most important parameter. Oxygen saturation and respiratory rate are also important but monitoring blood pressure takes precedence in this situation.
What is a condition where the airways become swollen and produce extra mucus, making it difficult to breathe, often associated with COPD?
- A. Chronic bronchitis
- B. Pneumonia
- C. Emphysema
- D. Tuberculosis
Correct Answer: A
Rationale: Rationale:
1. Chronic bronchitis is characterized by inflammation of the airways leading to excess mucus production.
2. It is a common symptom of COPD, obstructing airflow and causing breathing difficulties.
3. Pneumonia, emphysema, and tuberculosis do not primarily involve airway inflammation and mucus production as seen in chronic bronchitis.
What is a blood clot that forms in a vein, often in the legs, and can cause serious complications if it travels to the lungs?
- A. Deep vein thrombosis (DVT)
- B. Pulmonary embolism
- C. Varicose veins
- D. Atherosclerosis
Correct Answer: A
Rationale: The correct answer is A: Deep vein thrombosis (DVT). DVT is a blood clot that forms in a deep vein, commonly in the legs. It can lead to serious complications if the clot dislodges and travels to the lungs, causing a pulmonary embolism. Varicose veins (C) are enlarged, twisted veins near the surface of the skin, not involving deep veins. Atherosclerosis (D) is the build-up of plaque in arteries, not related to vein clot formation. Pulmonary embolism (B) is a complication of DVT, not the initial clot formation in a vein.
