A nurse is caring for a client who has an elevated potassium level and is on a cardiac monitor.

The nurse is aware that hyperkalemia may be associated with changes to the T-wave. On the graphic, point and click on the area of the electrocardiogram (ECG) that represents the T-wave. (Selectable areas, or "Hot Spots," can be found by moving your cursor over the artwork until the cursor changes appearance, usually into a hand. Click only on the Hot Spot that corresponds to your answer.)
 

A. Empty the drainage from the pleuravac at the end of each shift: This is not a standard practice. Chest tube drainage systems typically have a built-in mechanism to handle drainage, and monitoring and recording the output is essential.

B. Report serosanguinous drainage in the pleuravac: Serosanguinous drainage (a mix of blood and serous fluid) can be expected in a hemothorax, especially initially. Reporting is necessary if there are significant changes in the amount or type of drainage.

C. Milk the chest tube every 4 hours to dislodge clotted blood: Milking or stripping the chest tube is generally not recommended as it can create high negative pressures that can damage lung tissue.

D. Assist with coughing and deep breathing exercises every hour: Encouraging coughing and deep breathing helps prevent atelectasis and promotes lung expansion, which is crucial for recovery from a hemothorax.

A. People mistakenly think they are experiencing seasonal allergies: While seasonal allergies may share some symptoms with the common cold, such as nasal congestion and sneezing, they are caused by allergens rather than viruses. This factor does not directly contribute to the high communicability of the common cold.

B. The virus is spread by individuals who don't have symptoms: The common cold is highly communicable because individuals infected with the virus can spread it to others even before they develop symptoms or when they have mild symptoms. This makes it challenging to prevent the spread of the virus, as infected individuals may not realize they are contagious.

C. Hand washing is not effective against the cold virus: Hand washing is an effective measure for preventing the spread of the common cold virus. Proper hand hygiene can help reduce the transmission of the virus from contaminated surfaces to the nose and mouth.

D. Use of over-the-counter cold products reduces immune resistance: Over-the-counter cold products may help relieve symptoms of the common cold but do not directly affect immune resistance. However, reliance on symptomatic relief without taking precautions to prevent the spread of the virus can contribute to its communicability.
