A client receives a prescription for ophthalmic ketorolac.
Prior to administering the medication, the nurse should review the medical record for which condition?

Rationale for Choice A:

Pursed-lip breathing:

Creates back pressure in the airways, which helps to keep them open longer during exhalation.

Slows down the breathing rate, allowing for more complete exhalation and better emptying of the lungs. Prevents air trapping, which can worsen shortness of breath.

Promotes relaxation and reduces anxiety, which can also help to improve breathing.

Rationale for Choice B:

Side-lying position with knees bent:

May not be the most effective position for improving gas exchange in a client with emphysema. Could potentially restrict chest expansion and make breathing more difficult.

May not be comfortable for all clients.

Rationale for Choice C:

Increasing breathing rate:

Can lead to hyperventilation, which can worsen shortness of breath and anxiety. Can also cause fatigue and muscle exhaustion.

Rationale for Choice D:

Raising hands above the head:

Does not significantly expand the diaphragm or improve gas exchange. May actually make breathing more difficult for some clients.

Choice A rationale:

Liquefying secretions is the most crucial action to address the client's immediate respiratory concerns. Thickened mucus obstructs airflow, leading to shortness of breath, productive cough, and difficulty breathing upon exertion. Increasing fluid intake thins mucus, making it easier to expel and improving ventilation. This directly addresses the client's current symptoms and promotes airway clearance.

Hydration and Mucociliary Clearance: Adequate hydration is indispensable for optimal mucociliary clearance, the natural mechanism that removes mucus from the airways. Fluids moisten the respiratory tract, allowing cilia (tiny hair-like structures) to effectively move mucus upwards, where it can be coughed out or swallowed.

Thinning Mucus: Water acts as a natural expectorant, thinning mucus and reducing its viscosity. This makes it easier for the client to cough up the mucus, clearing the airways and reducing the sensation of breathlessness.

Decreasing Mucus Production: Dehydration can trigger the body to produce more mucus as a protective response. By staying hydrated, the client can help prevent excessive mucus production, further easing symptoms.

Supporting Overall Respiratory Health: Proper hydration maintains the health of the respiratory system's tissues and cells, promoting efficient gas exchange and reducing inflammation.

Preventing Dehydration-Related Complications: Dehydration can exacerbate respiratory problems and lead to other complications, such as fatigue, headaches, and impaired immune function. Maintaining adequate fluid intake helps prevent these issues.

Key points to emphasize to the client:

Drink fluids throughout the day, even if not feeling thirsty.

Water is the best choice, but clear broths, juices, and herbal teas can also contribute to fluid intake. Avoid caffeine and alcohol, as they can be dehydrating.

Monitor urine output to ensure adequate hydration (urine should be pale yellow or clear).

Increase fluid intake during periods of increased mucus production, such as during respiratory infections or exercise.
