A nurse is preparing to administer digoxin to a client who has left-sided heart failure.
Which of the following clinical manifestations should the nurse expect to see in this client? (Select all that apply.).

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 A rationale:

A respiratory rate of 9/min and shallow respirations are indicative of hypoventilation, which can lead to an accumulation of carbon dioxide (CO2) in the blood. This condition results in respiratory acidosis (Choice D). In respiratory acidosis, the arterial pH is decreased (acidic) while the PaCO2 (partial pressure of carbon dioxide) is elevated.

Choice B rationale:

Respiratory alkalosis (Choice B) is characterized by a low PaCO2 and an elevated pH due to hyperventilation. Shallow respirations and a respiratory rate of 9/min do not align with this condition, as it typically involves rapid and deep breathing.

Choice C rationale:

Metabolic alkalosis (Choice C) results from a primary excess of bicarbonate (HCO3-) in the blood and is not associated with the given respiratory patterns. Shallow respirations and a low respiratory rate are more likely to lead to an accumulation of CO2, causing respiratory acidosis (Choice D).

Choice D rationale:

The correct answer is choice D. Shallow respirations and a respiratory rate of 9/min indicate hypoventilation, leading to an accumulation of CO2 in the blood. This condition results in respiratory acidosis, where the arterial pH is decreased. The body's compensatory response is to retain bicarbonate to normalize pH, but this can result in an elevated HCO3- level. The primary acid-base imbalance in this case is respiratory acidosis. .
