Basic metabolic panel

Echocardiogram

CT scan of abdomen

Blood cultures times 2 sets

Chest X-ray

Place on continuous cardiac monitor

CBC

12 lead EKG

Answer and Explanation

Correct Answer : F,H

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).

Correct Answer is A

Explanation

Choice A reason: Sodium polystyrene sulfonate is a medication that binds to excess potassium in the gastrointestinal tract and removes it from the body through feces. It is used to treat hyperkalemia, which is a high level of potassium in the blood. Hyperkalemia can cause cardiac arrhythmias and muscle weakness, and it is a common complication of AKI. Therefore, this medication should be administered first to lower the potassium level and prevent life-threatening complications.

Choice B reason: Sevelamer is a medication that binds to phosphorus in the gastrointestinal tract and removes it from the body through feces. It is used to treat hyperphosphatemia, which is a high level of phosphorus in the blood. Hyperphosphatemia can cause bone loss and soft tissue calcification, and it is a common complication of chronic kidney disease (CKD). However, it is not an urgent issue in AKI, and it does not affect the potassium level.

Choice C reason: Calcium acetate is a medication that also binds to phosphorus in the gastrointestinal tract and removes it from the body through feces. It has the same effect and indication as sevelamer, but it also provides calcium supplementation. However, it is not an urgent issue in AKI, and it does not affect the potassium level.

Choice D reason: Epoetin alfa, recombinant is a medication that stimulates the production of red blood cells in the bone marrow. It is used to treat anemia, which is a low level of hemoglobin or red blood cells in the blood. Anemia can cause fatigue, weakness, and shortness of breath, and it is a common complication of CKD and AKI. However, it is not an urgent issue in AKI, and it does not affect the potassium level.

A. Prepare for an abdominal catheter. B. Continue routine medications. C. Expect the insulin dosage to be reduced. D. Include potassium-rich foods in the diet.

Correct Answer is C

Explanation

Choice A reason: An abdominal catheter is used for peritoneal dialysis, not hemodialysis. Hemodialysis requires access to a large blood vessel, usually in the arm or leg.

Choice B reason: Routine medications may need to be adjusted or avoided before or after hemodialysis, depending on their effects on blood pressure, fluid balance, and electrolytes.

Choice C reason: Insulin dosage may need to be reduced during hemodialysis because insulin is removed by the dialyzer and blood glucose levels may drop. This is the correct statement to include in client education.

Choice D reason: Potassium-rich foods should be limited in the diet of clients with chronic kidney disease and hemodialysis, because potassium can build up in the blood and cause cardiac arrhythmias.
