A nurse is reviewing the laboratory results of a client who is taking a loop diuretic and notes the client's potassium level is 3.0 mEq/L. Which of the following physiological responses should the nurse expect related to the client's hypokalemia?

Choice A rationale:

Limiting fluid intake throughout the day is not a suitable instruction for a client diagnosed with emphysema. Emphysema is a chronic obstructive pulmonary disease (COPD), and adequate hydration is important for individuals with this condition. Dehydration can lead to thicker mucus in the airways, making it harder to breathe. Clients with emphysema should be encouraged to maintain proper hydration.

Choice B rationale:

Instructing the client to breathe in through her nose and out through pursed lips is a beneficial technique for improving gas exchange in emphysema. This breathing technique, known as pursed-lip breathing, helps slow down the exhalation and maintains positive pressure in the airways, which can prevent airway collapse. It also promotes better oxygen exchange and reduces the feeling of breathlessness.

Choice C rationale:

Consuming a low-protein diet is not advisable for a client with emphysema. Protein is essential for tissue repair and overall health. Clients with emphysema should follow a balanced diet to maintain their energy levels and support their respiratory function. Restricting protein intake is not a standard recommendation for managing emphysema.

Choice D rationale:

Instructing the client to rest in a supine position is not a suitable recommendation. Emphysema clients often find it easier to breathe when in an upright or semi-Fowler's position, as it allows for better lung expansion and oxygen exchange. Resting in a supine position can compromise their ability to breathe effectively and may worsen their symptoms.

Choice D rationale:

The nurse should seek clarification for the prescribed medication Propranolol when caring for a client with an exacerbation of asthma. Propranolol is a non-selective beta-blocker, and its use can exacerbate bronchoconstriction and potentially worsen asthma symptoms. In patients with asthma, non-selective beta-blockers are generally contraindicated. The nurse should consult with the provider to ensure that Propranolol is the appropriate choice, as there may be safer alternatives to manage the client's condition without worsening their asthma.

Choice A rationale:

Prednisone is a corticosteroid commonly used to reduce inflammation and manage asthma exacerbations. It is an appropriate medication for asthma management and does not require clarification.

Choice B rationale:

Montelukast is a leukotriene receptor antagonist that is also used in the management of asthma. It helps to reduce airway inflammation and bronchoconstriction. Montelukast is an appropriate choice for asthma and does not need further clarification.

Choice C rationale:

Aminophylline is a bronchodilator that can be used in the treatment of asthma. While it may have potential side effects and interactions, it is not the first medication that needs clarification in this scenario. Propranolol, due to its potential to worsen asthma symptoms, takes precedence.
