A nurse is caring for a client who develops the rhythm below. The client is unresponsive, pulseless, and apneic. Which of the following actions should the nurse expect to do first?

A) Go to the emergency department:
An immediate trip to the emergency department is generally not required for a peak expiratory flow rate (PEFR) of 82%. The PEFR of 82% indicates that the client’s airflow is reduced, but it is not necessarily an emergency. PEFR readings are typically classified into zones: green (80-100% of personal best), yellow (50-79% of personal best), and red (below 50% of personal best). A reading of 82% is in the yellow zone, which suggests that the client is experiencing some degree of airway obstruction or worsening asthma symptoms

B) Continue to use salmeterol and fluticasone as prescribed:
While salmeterol (a long-acting beta agonist) and fluticasone (a corticosteroid) are important for long-term asthma control, continuing their use without additional intervention is not the most appropriate action when the PEFR is 82%. A PEFR of 82% indicates that the client’s asthma is not well controlled at the moment, and the nurse should recommend additional short-acting relief to help open the airways (e.g., a rescue inhaler like albuterol.

C) Administer an additional rescue dose of Albuterol:
The correct immediate action is to administer a rescue dose of albuterol. Albuterol is a short-acting beta-agonist that helps open the airways quickly during an asthma exacerbation. A PEFR of 82% falls in the yellow zone, suggesting some obstruction but not an emergency situation. In this case, administering an additional rescue dose of albuterol can help improve airflow and bring the PEFR closer to normal.

D) Call the physician:
While it may be necessary to call the physician if the client’s asthma symptoms do not improve after using a rescue inhaler or if there is a significant decline in symptoms, the first immediate action should be to use a rescue medication like albuterol. Calling the physician may be appropriate after assessing the response to the rescue medication, but it is not the first step in managing a PEFR of 82%.

A) Jaundice:
Carbidopa-levodopa works by increasing dopamine levels in the brain to help alleviate symptoms of Parkinson's disease, but it is not typically associated with liver dysfunction that would lead to jaundice. If jaundice were to occur, it could indicate liver problems, which would need to be evaluated further, but this is not a typical side effect of Sinemet.

B) Hyperglycemia:
Sinemet primarily affects dopamine levels in the brain and does not have a direct impact on blood sugar regulation. However, long-term use of certain medications, especially corticosteroids or other specific treatments, can affect glucose levels, but carbidopa-levodopa is not typically linked to hyperglycemia.

C) Hypertension:

Carbidopa-levodopa may lead to fluctuations in blood pressure, including lowering blood pressure, especially when the patient is changing positions. However, hypertension is not a typical response to this medication. Instead, patients may experience orthostatic hypotension, which is more common with carbidopa-levodopa.

D) Orthostatic hypotension:
Orthostatic hypotension is a well-recognized and common side effect of carbidopa-levodopa. This occurs because Sinemet affects the autonomic nervous system, which can cause a decrease in blood pressure when moving from a sitting or lying position to standing. Patients on carbidopa-levodopa should be advised to rise slowly to minimize the risk of dizziness or fainting due to orthostatic hypotension.
