The nurse is caring for a patient with Addison's disease who is scheduled for discharge. When teaching the patient about hormone replacement therapy, the nurse should address what topic?

A. Respiratory acidosis:
This occurs when there is inadequate removal of carbon dioxide (CO2) by the respiratory system. In the case of the patient post-op from knee surgery receiving Morphine, the opioid can cause respiratory depression, leading to the retention of CO2 and the development of respiratory acidosis. Signs include a decreased respiratory rate and drowsiness.

B. Hypokalemia:
This is a condition characterized by low levels of potassium in the blood. While opioids can cause constipation, they are not directly associated with hypokalemia.

C. Metabolic acidosis:
This occurs when there is an increase in acid production or a loss of bicarbonate, leading to an imbalance in the body's acid-base status. The symptoms of metabolic acidosis are not typically associated with opioid use.

D. Respiratory alkalosis:
This occurs when there is excessive elimination of CO2, leading to decreased carbon dioxide levels in the blood. Opioids, especially in higher doses, are more likely to cause respiratory depression and acidosis rather than alkalosis. The patient's low respiratory rate and drowsiness are indicative of respiratory acidosis rather than alkalosis.

A. Inform the primary care provider that the patient may have an infection:
Explanation: The presence of an elevated oral temperature and new onset of fine crackles on lung auscultation suggests a potential respiratory infection, which is a significant concern in a patient with sickle cell disease. Notifying the primary care provider allows for further evaluation and appropriate management of the infection.

B. Liaise with the respiratory therapist and consider high-flow oxygen:
Explanation: While oxygenation may be necessary, especially if the patient is experiencing respiratory distress, addressing the potential infection is the priority. Consulting with the respiratory therapist and considering high-flow oxygen can be part of the overall plan based on the primary care provider's recommendations.

C. Apply supplementary oxygen by nasal cannula:
Explanation: Providing oxygen support may be necessary, but it should be done in consultation with the primary care provider, who can guide the appropriate level of oxygen therapy based on the patient's condition.

D. Administer bronchodilators by nebulizer:
Explanation: Bronchodilators are typically used for conditions like asthma or COPD, and their use might not be the primary intervention in the context of a sickle cell crisis with signs of a potential respiratory infection. Addressing the infection takes precedence, and the primary care provider's input is essential in determining the appropriate course of action.
