The client is on hydrochlorothiazide and digoxin. What effect can the nurse expect?
- A. Hydrochlorothiazide increases digoxin levels.
- B. Hydrochlorothiazide decreases digoxin levels.
- C. Hydrochlorothiazide decreases potassium, increasing the risk of digoxin toxicity.
- D. Digoxin can increase the effectiveness of hydrochlorothiazide.
Correct Answer: C
Rationale: The correct answer is C because hydrochlorothiazide is a diuretic that can lead to hypokalemia (decreased potassium levels), which increases the risk of digoxin toxicity as digoxin requires adequate potassium levels for proper function.
Choice A is incorrect because hydrochlorothiazide does not increase digoxin levels. Choice B is incorrect because hydrochlorothiazide can actually increase digoxin levels due to potential electrolyte disturbances. Choice D is incorrect as digoxin does not affect the effectiveness of hydrochlorothiazide.

The client on amiodarone develops symptoms of hypothyroidism. What is the nurse's best response?
- A. Notify the healthcare provider immediately.
- B. Reassure the client that this is a common side effect of amiodarone.
- C. Monitor the client's thyroid function tests regularly.
- D. Discontinue the amiodarone immediately.
Correct Answer: C
Rationale: The correct response is C: Monitor the client's thyroid function tests regularly. This is the best approach because amiodarone can cause hypothyroidism, so monitoring thyroid function tests allows early detection and appropriate management. Option A is not necessary unless the client presents with severe symptoms. Option B is incorrect as hypothyroidism is a serious side effect that requires monitoring and possible treatment adjustments. Option D is not recommended as abruptly stopping amiodarone can lead to serious cardiac arrhythmias. Regular monitoring ensures timely intervention if thyroid levels are abnormal.
What is a condition where the lung's air sacs become inflamed and fill with fluid or pus, causing cough, fever, chills, and difficulty breathing?
- A. Pneumonia
- B. Tuberculosis
- C. Asthma
- D. Bronchitis
Correct Answer: A
Rationale: The correct answer is A: Pneumonia. Pneumonia is characterized by inflammation and fluid or pus accumulation in the lung's air sacs. This leads to symptoms such as cough, fever, chills, and difficulty breathing. Tuberculosis (B) is a bacterial infection affecting the lungs but does not always involve fluid accumulation. Asthma (C) is a chronic respiratory condition characterized by airway inflammation and bronchospasms, not fluid-filled air sacs. Bronchitis (D) is inflammation of the bronchial tubes, not the air sacs in the lungs.
What is a condition where a blood clot forms in a deep vein, usually in the legs, and can lead to serious complications if it travels to the lungs?
- A. Deep vein thrombosis (DVT)
- B. Pulmonary embolism
- C. Varicose veins
- D. Raynaud's disease
Correct Answer: A
Rationale: The correct answer is A: Deep vein thrombosis (DVT). DVT is a condition where a blood clot forms in a deep vein, typically in the legs. It can lead to serious complications if the clot breaks loose and travels to the lungs, causing a pulmonary embolism. Varicose veins (C) are enlarged, twisted veins, not related to blood clots. Raynaud's disease (D) is a condition affecting blood flow to the extremities, not related to clot formation. Pulmonary embolism (B) is a consequence of DVT, not the initial condition of clot formation in the deep veins.
What is a chronic condition where the bronchial tubes in the lungs become inflamed and narrowed, often caused by smoking?
- A. Chronic bronchitis
- B. Emphysema
- C. Asthma
- D. Tuberculosis
Correct Answer: A
Rationale: The correct answer is A: Chronic bronchitis. Chronic bronchitis is characterized by inflammation and narrowing of the bronchial tubes, often caused by smoking. This condition leads to persistent coughing and mucus production. Emphysema (B) is a separate condition where the air sacs in the lungs are damaged, causing shortness of breath. Asthma (C) is a chronic respiratory condition characterized by airway inflammation and bronchospasms, triggered by various factors. Tuberculosis (D) is a bacterial infection that primarily affects the lungs, causing symptoms like coughing up blood and weight loss. Chronic bronchitis specifically relates to the inflammation and narrowing of the bronchial tubes due to smoking.
