A client is admitted with an exacerbation of COPD. He has a long history of chronic bronchitis.
What physical finding does the nurse expect in a client with chronic bronchitis?
SpO2 >92%.
Underweight.
Bradypnea.
Productive cough.
The Correct Answer is D
A client with chronic bronchitis is expected to have a cough that produces sputum for at least 3 months during two successive years. This is due to the hyperplasia of mucous glands and bronchial wall inflammation that occur in chronic bronchitis.
Choice A is wrong because SpO2 >92% is not a specific finding for chronic bronchitis.
SpO2 is a measure of oxygen saturation in the blood and can vary depending on many factors, such as altitude, smoking, and lung diseases. SpO2 may be lower than normal in COPD patients due to airflow obstruction and impaired gas exchange.
Choice B is wrong because underweight is not a typical finding for chronic bronchitis.
Underweight may be more associated with emphysema, which is another component of COPD that involves the destruction of alveolar walls and enlargement of air spaces. Emphysema can cause weight loss due to increased work of breathing and decreased appetite.
Choice C is wrong because bradypnea is not a common finding for chronic bronchitis.
Bradypnea is abnormally slow breathing rate and can be caused by various conditions, such as brain injury, drug overdose, or sleep apnea. Chronic bronchitis usually causes tachypnea, which is abnormally fast breathing rate, due to hypoxia and hypercapnia.

Correct Answer is D
Explanation
This is because the fight-or-flight response activates the sympathetic nervous system, which causes the pupils to dilate to allow more light and improve vision.
Choice A is wrong because the fight-or-flight response increases blood pressure by constricting blood vessels and increasing heart rate.
Choice B is wrong because the fight-or-flight response causes bronchial airway dilation to allow more oxygen intake and facilitate breathing.
Choice C is wrong because the fight-or-flight response causes hyperglycemia by stimulating the release of glucose from the liver and muscles to provide energy.
Normal ranges for blood pressure are 90/60 mmHg to 120/80 mmHg, for blood glucose are 70 mg/dL to 100 mg/dL, and for pupil size are 2 mm to 6 mm.
Correct Answer is A
Explanation
This is because hypokalemia (low potassium level in the blood) can cause abnormal heart rhythms (arrhythmia) that can be life-threatening and require urgent medical attention. A cardiac monitor can help detect and treat any arrhythmia that may occur.
Choice B is wrong because administering a laxative can worsen hypokalemia by causing more potassium loss through the digestive tract. Laxative use is one of the possible causes of hypokalemia.
Choice C is wrong because placing the client on seizure precautions is not a priority intervention for hypokalemia. Seizures are not a common symptom of hypokalemia, although muscle weakness and cramps may occur.
Choice D is wrong because restricting high potassium foods is not a priority intervention for hypokalemia. In fact, increasing potassium intake through foods or supplements may be helpful in less serious cases of hypokalemia. However, this should be done according to the doctor’s recommendation and with careful monitoring of blood potassium levels.
Normal blood potassium levels for an adult range from 3.6 to 5.2 millimoles per liter (mmol/L). A very low potassium level (less than 2.5 mmol/L) can be life threatening.
