A nurse is teaching an adolescent client who has asthma about medications to treat an acute asthma attack. Which of the following medications should the nurse include in the instructions?

Choice A rationale:
Increasing potassium consumption is unrelated to cephalexin, an antibiotic. It is not a necessary precaution or action to take while on this medication.
Choice B rationale:
Applying lotion to the skin to relieve itching is not related to cephalexin use. Itching is not a common side effect of this antibiotic, so the client's statement indicates a misunderstanding of the teaching.
Choice C rationale:
Avoiding sun exposure is essential while taking cephalexin because it is known to cause photosensitivity reactions. Sun exposure can lead to severe skin reactions, so the client's statement indicates an understanding of the teaching.
Choice D rationale:
Keeping the medication refrigerated is not necessary for cephalexin oral suspension. It should be stored at room temperature unless specified otherwise by the manufacturer. The client's statement suggests a misunderstanding of the medication storage instructions.

Choice A rationale:

Preparing an endotracheal tube for intubation is not the first action the nurse should take in this situation. Intubation is an invasive procedure and should be reserved for cases where other, less invasive methods of airway management have failed.

Choice B rationale:

Inserting a plastic oral airway may help maintain the airway in some situations, but it is not the first action to take when the client's airway is obstructing and their oxygen saturation is low.

Choice C rationale:

Providing oxygen using a manual resuscitation bag (bag-valve-mask device) is the correct first action. This allows the nurse to manually assist the client's breathing and deliver oxygen more effectively than just providing supplemental oxygen through a nasal cannula or face mask.

Choice D rationale:

Performing a head tilt with a chin-lift is a basic airway maneuver, but it may not be sufficient in this situation, especially if the airway is completely obstructed. Providing oxygen with a manual resuscitation bag takes precedence.
