The nurse is preparing to administer sodium polystyrene sulfonate (Kayexalate) rectally to a patient with an irregular pulse and weakness of the lower extremities.
What laboratory finding does the nurse determine is the reason for this treatment?

Choice A rationale

While swimming can be less likely to trigger asthma attacks than some other sports, children with asthma should not necessarily stop playing basketball if it's something they enjoy. Proper management and understanding triggers are crucial.

Choice B rationale

Avoiding triggers that cause an asthma attack is a fundamental part of asthma management. Triggers can vary from person to person and may include allergens, smoke, cold air, and exercise.

Choice C rationale

The peak expiratory flow meter should be used regularly, typically twice a day, to monitor asthma control, not just once per week. Regular use helps identify worsening symptoms early.

Choice D rationale

Cromolyn sodium is a preventive medication and should be taken regularly as prescribed, not just at the first sign of breathing difficulty.

Choice A rationale

Administering post-procedure antibiotics is not typically required for a bronchoscopy unless there is evidence of infection. The procedure itself does not inherently pose a high risk of infection requiring antibiotics as a preventative measure.

Choice B rationale

Providing pre-procedure sedation is important to ensure the client is comfortable and relaxed during the bronchoscopy. This helps minimize discomfort and anxiety associated with the procedure.

Choice C rationale

Ensuring the client is NPO (nothing by mouth) for a specific period before the procedure is crucial to prevent aspiration. Aspiration can occur if the client has food or liquid in their stomach, posing a serious risk during the insertion of the bronchoscope.

Choice D rationale

Encouraging the client to drink plenty of fluids before the procedure is not appropriate because the client needs to be NPO to prevent aspiration risks during the bronchoscopy.
