A nurse is caring for a postoperative client who has an indwelling urinary catheter. Which of the following actions should the nurse take when removing the catheter?

A) Decreased responsiveness of airways to allergens:
Asthma is characterized by an increased responsiveness of the airways to various triggers, including allergens, rather than a decreased responsiveness. This heightened sensitivity leads to bronchoconstriction and inflammation, contributing to the symptoms of an asthma attack.

B) Suppressed bronchiolar inflammatory response:
During an asthma attack, there is an exaggerated bronchiolar inflammatory response rather than suppression. Inflammatory mediators cause swelling, mucus production, and constriction of the airways, making it difficult for the client to breathe.

C) Acute loss of alveolar elasticity:
The loss of alveolar elasticity is more characteristic of conditions like emphysema rather than asthma. Asthma primarily involves the airways rather than the alveoli, with symptoms resulting from bronchoconstriction and inflammation rather than loss of elasticity.

D) Inability to exhale retained carbon dioxide:
During an acute asthma attack, bronchoconstriction and airway inflammation lead to air trapping and difficulty in exhaling. This results in the retention of carbon dioxide and subsequent respiratory distress. The inability to exhale effectively exacerbates symptoms, making it a key contributing factor to the manifestations of an asthma attack.

A) Assist the client with toileting at least once every 4 hr:
Assisting the client with toileting every 4 hours can help prevent incontinence and associated skin issues, but the frequency should be tailored to the client's individual needs. A rigid schedule may not be necessary and could cause unnecessary disturbances. Personalized care plans based on the client's toileting habits and preferences are more effective.

B) Turn off all lights in the client's room at night:
Turning off all lights at night can lead to increased disorientation and risk of falls for a client with dementia. A better approach is to use a nightlight or low-level lighting to maintain safety and provide enough illumination for the client to navigate the room if they wake up. This helps balance restfulness and safety.

C) Place the client's bed at the lowest height:
Placing the client's bed at the lowest height is a critical safety measure to reduce the risk of injury from falls, which are common in clients with dementia. It makes it easier for the client to get in and out of bed safely and minimizes the potential for serious injury if a fall does occur. This intervention is straightforward and highly effective in enhancing client safety.

D) Request a prescription for a nightly sedative:
Requesting a nightly sedative should be considered only after exploring non-pharmacological interventions for sleep disturbances. Sedatives can have significant side effects, including increased confusion and fall risk. Behavioral strategies, environmental modifications, and routine establishment should be prioritized to promote better sleep hygiene for clients with dementia.
