A client presented to the emergency room by ambulance with complaints of nausea, diaphoresis, SOB, and severe, squeezing chest pain described as "an elephant sitting on his chest. 21 of oxygen via nasal cannula was started in route to the ED. In addition, three doses of nitroglycerin SL. Aspirin 325mg SL and morphine 2 mg IV were administered prior to arrival, without relief. EKG shows ST elevation with a HR 122. BP 156/94, RR 22 and pulse ox 91% A "STEMI Alert" on this is called overhead. The nurse recognizes the priority intervention to treat this client is to:

A. Decrease activity, increase bronchodilator use, and encourage pursed lip breathing: This is not the most appropriate intervention for bacterial pneumonia. While bronchodilators and pursed-lip breathing can help in certain conditions (like chronic obstructive pulmonary disease), bacterial pneumonia primarily requires treatment with antimicrobials to address the infection. Decreasing activity may be necessary based on the patient’s condition, but it does not directly address the pneumonia or intrapulmonary shunting.

B. Increase fluid intake, administer antimicrobials & facilitate adequate coughing: Increasing fluid intake helps to thin secretions and improve expectoration. Administering antimicrobials is essential to treat bacterial pneumonia. Facilitating adequate coughing allows the patient to clear mucus from the airways, improving ventilation and reducing intrapulmonary shunting (which occurs when blood is diverted to areas of the lung that are not ventilated). This is the most appropriate set of interventions.

C. Place in prone position, begin steroid therapy & check peak flow monitor use: The prone position and steroid therapy are more commonly used in conditions like acute respiratory distress syndrome (ARDS), not bacterial pneumonia. Checking a peak flow monitor is more appropriate for asthma or other obstructive lung diseases, not bacterial pneumonia.

D. Increase oxygen, administer a cough suppressant, and place client on bedrest: While increasing oxygen is important to support oxygenation in pneumonia, administering a cough suppressant would be inappropriate as it would prevent the patient from clearing secretions effectively. Bedrest may be appropriate but should not be the primary focus when treating bacterial pneumonia.

A. Change position slowly to prevent orthostatic hypotension.: One of the common side effects of carbidopa/levodopa is orthostatic hypotension, which is a drop in blood pressure when standing up from a sitting or lying position. Patients should be taught to change positions slowly to help prevent dizziness or fainting.

B. Decrease the dose as muscle tremors subside.: The dose of carbidopa/levodopa should not be reduced without a physician's guidance, even if symptoms such as muscle tremors subside. This medication is used to help manage symptoms of Parkinson's disease, and any changes in dosage should be made under the supervision of a healthcare provider.

C. This is a safe medication associated with minimal side effects.: Carbidopa/levodopa is a commonly used medication for Parkinson's disease, but it is associated with several potential side effects, such as nausea, dizziness, dyskinesia (involuntary movements), and orthostatic hypotension. It is important to discuss these potential side effects with the patient.

D. Double the dose the next scheduled time if a dose is missed.: If a dose of carbidopa/levodopa is missed, the patient should not double the next dose. They should follow the instructions provided by their healthcare provider or pharmacist, typically taking the missed dose as soon as they remember, unless it is almost time for the next dose.
