A nurse is assisting with collecting data on a client who is on a continuous ECG monitor. The client's ECG tracing shows no identifiable P waves and an irregular ventricular rate. The nurseshould recognize the client is experiencing which of the following cardiac dysrhythmias?

A. Inspiratory stridor - This is associated with upper airway obstruction and is not indicative of a pneumothorax.

B. Expiratory wheeze - Wheezing is commonly associated with lower airway conditions such as asthma or chronic obstructive pulmonary disease (COPD), not pneumothorax.

C. Coarse crackles - Coarse crackles are typically heard in conditions such as pneumonia or pulmonary edema, not pneumothorax.

D. Absence of breath sounds - This is a key manifestation of a pneumothorax. The air in the pleural space can prevent the lung from fully expanding, leading to the absence of breath sounds on the affected side.

A. “I will notify my provider before taking any other medications.” - This statement reflects an understanding of the need to check for potential interactions with other medications, which is an appropriate response.

B. “I have made an appointment to see my dentist next week.” - Dental care is important, and

scheduling an appointment with the dentist is a responsible action. However, it does not indicate a misunderstanding about the medication.

C. “I will take this medication with meals.” - Taking phenytoin with meals is a correct instruction as it can help reduce gastrointestinal side effects.

D. "I'll be glad when my seizures stop so I can quit taking this medicine." - This statement

indicates a misunderstanding about the chronic nature of anti-seizure medications. The client needs further education on the importance of continuing the medication even if seizures stop.
