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. Document how many inches the tube has been inserted: While documentation of the tube insertion depth is important, it is not the highest priority immediately after intubation. Ensuring proper placement and ventilation take precedence.

B. Auscultate both lungs for the presence of breath sounds: This is the priority action to confirm that the endotracheal tube is correctly placed in the trachea and that both lungs are being ventilated adequately. Absence of breath sounds on one side could indicate mainstem intubation or displacement of the tube.

C. Secure the endotracheal tube to prevent dislodgement: Securing the tube is important, but it should be done after confirming proper placement and ventilation.

D. Obtain a chest x-ray to ensure correct tube placement: While a chest x-ray is often performed after intubation to confirm tube placement, it is not the immediate priority. Auscultation provides more immediate feedback on the effectiveness of ventilation.

A. Consumes spicy snacks daily: Consuming spicy snacks daily is not a known risk factor for laryngeal cancer. Risk factors for laryngeal cancer typically include tobacco use, alcohol consumption, exposure to certain chemicals, and occupational hazards.

B. Uses flavored chewing tobacco: Chewing tobacco, especially flavored varieties, is a known risk factor for laryngeal cancer. Tobacco contains carcinogenic substances that can damage the cells of the larynx, increasing the risk of cancer development.

C. Employed as x-ray technician: Being employed as an x-ray technician is not a known risk factor for laryngeal cancer. However, prolonged exposure to radiation may increase the risk of other types of cancer, such as lung cancer.

D. Partner smokes cigarettes: Secondhand smoke exposure from a partner who smokes cigarettes is a risk factor for laryngeal cancer. Inhaling tobacco smoke, even indirectly, can expose the individual to carcinogens that may contribute to the development of cancer.

E. Employed as industrial painter: Occupational exposure to certain chemicals, such as those found in paint and industrial solvents, is a known risk factor for laryngeal cancer. Industrial painters may be exposed to carcinogens through inhalation or skin contact, increasing their risk of developing cancer.
