A nurse is assisting with the care of a client who is receiving penicillin via intermittent IV bolus. Which of the following should the nurse recognize as a clinical manifestation of anaphylaxis?

Choice A: This is incorrect because applying petroleum jelly to the client's nares can interfere with oxygen delivery and cause skin breakdown. The nurse should use water-soluble lubricant or saline spray to moisten the nares and prevent dryness from oxygen therapy.

Choice B: This is correct because initiating fall precautions can prevent injury and complications for the client who has aspirated pneumonia and hypoxia. The client may have altered mental status, weakness, or dizziness due to hypoxia, infection, or medications. The nurse should use bed alarms, side rails, and assistive devices as needed.

Choice C: This is incorrect because maintaining the client in a supine position can worsen hypoxia and pneumonia by decreasing lung expansion and increasing secretions. The nurse should elevate the head of the bed at least 30 degrees and encourage frequent position changes to improve ventilation and drainage.

Choice D: This is incorrect because implementing contact precautions is not indicated for the client who has aspirated pneumonia and hypoxia. Aspirated pneumonia is caused by inhalation of foreign material into the lungs, not by transmission of microorganisms from person to person. The nurse should use standard precautions and droplet precautions if the client has a cough or sputum production.

Choice A reason: Applying restraints to the client is not an appropriate action, as it can cause injury or suffocation to the client during a seizure. The nurse should protect the client from harm by removing any nearby objects and padding the side rails.

Choice B reason: Administering an IV bolus of lorazepam is an appropriate action, as lorazepam is an anticonvulsant drug that can stop or shorten the duration of a seizure by enhancing the inhibitory effects of gamma-aminobutyric acid (GABA) in the brain.

Choice C reason: Placing the client in the prone position is not an appropriate action, as it can obstruct the airway and cause respiratory distress or aspiration during a seizure. The nurse should place the client in the side-lying position to facilitate drainage of oral secretions and prevent tongue biting.

Choice D reason: Inserting a tongue blade into the client's mouth is not an appropriate action, as it can cause oral trauma or choking during a seizure. The nurse should never force anything into the client's mouth during a seizure and should allow them to breathe spontaneously.
