The Correct Answer is {"dropdown-group-1":"E","dropdown-group-2":"C"}
Potassium Levels: The postoperative potassium level for the client is 3.0 mEq/L, which falls below the normal range of 3.5 to 5 mEq/L. Potassium is a critical electrolyte necessary for the proper functioning of cardiac muscles. It plays a pivotal role in maintaining the electrical conductivity of the heart. Hypokalemia, or low potassium levels, can disrupt this electrical conductivity, leading to abnormal heart rhythms or arrhythmias. Arrhythmias can manifest as palpitations, irregular heartbeats, or more severe cardiac events, which can be life-threatening if not addressed promptly.
Importance of Potassium in Cardiac Function: Potassium is essential for the repolarization phase of the cardiac action potential. It helps in the return of the cell to its resting state after each heartbeat. A deficiency in potassium disrupts this balance, increasing the risk of erratic heartbeats and arrhythmias. Low potassium can prolong the QT interval on an electrocardiogram (ECG), which is a marker for potential arrhythmic events.
Clinical Implications: For a postoperative client, maintaining electrolyte balance is crucial. Surgery and anesthesia can affect fluid and electrolyte levels, making it essential to monitor and correct any imbalances. The decrease in potassium levels from 3.5 mEq/L preoperatively to 3.0 mEq/L postoperatively highlights a trend that must be addressed to prevent complications such as arrhythmias.
Preventative Measures: To mitigate the risk of arrhythmias, the healthcare team should consider interventions to correct the hypokalemia. This may include administering potassium supplements orally or intravenously, depending on the severity and clinical context. Continuous cardiac monitoring may also be warranted to detect and manage any emerging arrhythmic events promptly.

Correct Answer is A
Explanation
A. Propranolol is a beta-blocker medication commonly used to treat hypertension, angina, and certain heart rhythm disorders. However, it is contraindicated in clients with a history of asthma or other obstructive airway diseases due to its potential to cause bronchoconstriction and exacerbate respiratory symptoms.
B. Migraines:
Propranolol is actually commonly used for the prophylactic treatment of migraines, particularly in individuals with frequent or severe migraines. It helps reduce the frequency and severity of migraine attacks by blocking the release of certain chemicals in the brain.
C. Glaucoma:
Propranolol can be used in the treatment of glaucoma, particularly when other treatments have been ineffective. It works by reducing intraocular pressure, which can help prevent vision loss associated with glaucoma.
D. Depression:
Propranolol is not contraindicated in clients with depression. In fact, it may sometimes be used off-label to manage certain symptoms of anxiety or performance anxiety. However, it is important to monitor clients with depression closely when prescribing propranolol, as it may interact with other medications used to treat depression or worsen certain depressive symptoms.
Correct Answer is D
Explanation
A. Collect a urine sample from the client: While collecting a urine sample may be necessary for further assessment, it is not the priority in this situation. The client's symptoms of lower back pain, feeling chilled, and itching suggest a potential transfusion reaction, which requires immediate attention to ensure the client's safety. Therefore, collecting a urine sample is not the most appropriate initial action.
B. Return the platelet bag and tubing to the blood bank: Returning the platelet bag and tubing to the blood bank may be necessary after stopping the infusion, but it is not the first action the nurse should take. Stopping the infusion and assessing the client's condition are the immediate priorities to address the potential transfusion reaction.
C. Notify the provider: While it is important to notify the provider about the client's symptoms and the suspected transfusion reaction, this action should follow after stopping the infusion and assessing the client's condition. Immediate intervention to ensure the client's safety takes precedence over contacting the provider.
D. Stop the infusion: This is the correct action. The client's symptoms of lower back pain, feeling chilled, and itching are indicative of a potential transfusion reaction, such as febrile non-hemolytic transfusion reaction or allergic reaction. The immediate priority is to stop the infusion to prevent further administration of platelets and assess the client's condition. This action takes precedence over other interventions as addressing the client's safety and well-being is paramount in the event of a transfusion reaction.
