A nurse is providing teaching to the parents of a child who has streptococcal pharyngitis about ways to prevent disease transmission. Which of the following responses by the parents indicates an understanding of the teaching?

Continuing to monitor the client is the appropriate action for the nurse to take, as a rise in the water seal chamber with client inspiration is a normal and expected finding. The water seal chamber acts as a one-way valve that allows air to exit from the pleural space and prevents air from entering. The water level in this chamber fluctuates with breathing, rising with inspiration and falling with expiration. This indicates that the chest tube system is functioning properly and that there is no air leak.

a) Immediately notifying the provider is not necessary, as a rise in the water seal chamber with client inspiration is not an abnormal or urgent finding. The nurse should only notify the provider if there are signs of complications, such as persistent bubbling in the water seal chamber, which indicates an air leak, or no fluctuation in the water level, which indicates an obstruction or resolution of pneumothorax.
b) Clamping the chest tube near the water seal is not advisable, as it can cause increased pressure in the pleural space and lead to tension pneumothorax. Clamping the chest tube should only be done for a brief period of time and under specific circumstances, such as changing the drainage system, assessing for an air leak, or preparing for chest tube removal.
d) Repositioning the client toward the left side is not helpful, as it does not affect the water level in the water seal chamber. The nurse should position the client according to their comfort and condition, and avoid placing them flat or on their affected side, as this can impair drainage and ventilation.

Heparin is an anticoagulant that prevents the formation of new clots and the extension of existing clots. It is the drug of choice for treating acute pulmonary embolism, which is a life-threatening condition caused by a blood clot that travels to the lungs and blocks a pulmonary artery.

a) Dexamethasone is a corticosteroid that reduces inflammation and suppresses immune response. It is not indicated for treating pulmonary embolism, but it may be used for other pulmonary conditions, such as asthma or COPD.
b) Atropine is an anticholinergic that blocks the action of acetylcholine and increases heart rate and cardiac output. It is not indicated for treating pulmonary embolism, but it may be used for bradycardia or asystole.
d) Furosemide is a loop diuretic that increases urine output and reduces fluid volume and blood pressure. It is not indicated for treating pulmonary embolism, but it may be used for heart failure or edema.
