A nurse is collecting data from a client who has atrial fibrillation. When documenting the quality of the client's pulse, which of the following terms should the nurse use?

a. Potassium level of 3.0 mEq/L: Hypokalemia is a potential adverse effect of digoxin, and a

potassium level of 3.0 mEq/L is below the normal range. Low potassium levels can increase the risk of digoxin toxicity.

b. Heart rate of 66/min: A heart rate of 66/min is within the normal range. Digoxin is used to

treat conditions like atrial fibrillation, and the heart rate should be within an appropriate range for the client's condition.

c. BP of 132/82 mm Hg: Blood pressure within the normal range does not require immediate reporting in the context of digoxin administration.

d. Digoxin level of 1.2 ng/ml: The digoxin level of 1.2 ng/ml is within the therapeutic range, and it does not require immediate reporting.

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.
