The nurse is teaching a client with cancer about skin care for the portal site receiving external beam radiation. Which client action regarding skin care indicates a need for further teaching?

a) Basic metabolic panel: This is a blood test that measures the levels of electrolytes, glucose, calcium, and kidney function. It is not a priority order for this client because her glucose level is within the normal range and her symptoms are not indicative of electrolyte imbalance or kidney failure.

b) Echocardiogram: This is a test that uses sound waves to create images of the heart and its valves, chambers, and blood flow. It is not a priority order for this client because her chest discomfort may not be related to a cardiac problem and her SpO2 is normal, indicating adequate oxygenation.

c) CT scan of abdomen: This is a test that uses X-rays to create detailed pictures of the organs and structures in the abdomen. It is not a priority order for this client because her abdominal pain is not severe or acute and her nausea and poor appetite may be due to her illness or dialysis.

d) Blood cultures times 2 sets: This is a test that checks for the presence of bacteria or fungi in the blood. It is not a priority order for this client because she does not have signs of infection such as fever, chills, or leukocytosis.

e) Chest X-ray: This is a test that uses X-rays to create images of the lungs and chest wall. It is not a priority order for this client because she does not have respiratory symptoms such as cough, shortness of breath, or wheezes.

f) Place on continuous cardiac monitor: This is an order that requires the nurse to attach electrodes to the client's chest and monitor the heart rate and rhythm continuously. This is a priority order for this client because she has a history of CAD and HTN and reports chest discomfort and lightheadedness, which could indicate a possible myocardial infarction (heart attack) or arrhythmia (irregular heartbeat).

g) CBC: This is a blood test that measures the number and types of blood cells, such as red blood cells, white blood cells, and platelets. It is not a priority order for this client because she does not have signs of anemia, bleeding, or infection.

h) 12 lead EKG: This is a test that records the electrical activity of the heart from 12 different angles. It can detect abnormalities in the heart's rhythm, conduction, or damage. This is a priority order for this client because she has a history of CAD and HTN and reports chest discomfort and lightheadedness, which could indicate a possible myocardial infarction (heart attack) or arrhythmia (irregular heartbeat).

Choice A reason: Redness and edema noted at the incision site are signs of inflammation, which are normal in the early stages of wound healing. The nurse should monitor the site for signs of infection, such as purulent drainage, increased pain, or fever.

Choice B reason: Apical heart rate of 100 to 110 beats/minute is a sign of tachycardia, which may be caused by pain, anxiety, dehydration, or blood loss. The nurse should assess the client's vital signs, fluid status, and hemoglobin level, and administer pain medication as prescribed.

Choice C reason: High-pitched sound heard upon inspiration is a sign of stridor, which is a life-threatening emergency that indicates airway obstruction. The nurse should call for help, administer oxygen, and prepare for intubation or tracheostomy.

Choice D reason: Pain rating of 8 on a scale of 0 to 10 is a sign of severe pain, which may impair the client's recovery and increase the risk of complications. The nurse should administer pain medication as prescribed and use non-pharmacological methods to relieve pain, such as positioning, distraction, or relaxation techniques.
