A client with acute renal injury (AKI) weighs 110.3 pounds (50 kg) and has a potassium level of 6.7 mEq/L (6.7 mmol/L) is admitted to the hospital. Which prescribed medication should the nurse administer first?
Reference Range:
Potassium [3.5 to 5 mEq/L (3.5 to 5 mmol/L)]
Sodium polystyrene sulfonate 15 grams by mouth.
Sevelamer one tablet by mouth.
Calcium acetate one tablet by mouth.
Epoetin alfa, recombinant 2,500 units subcutaneously.
The Correct Answer is A
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.

Explanation
For Potential Conditions:
The correct answer is c) Abdominal compartment syndrome.
Choice A reason: Pneumothorax is a condition where air leaks into the pleural space, causing lung collapse and impaired gas exchange. It can cause respiratory distress, hypoxia, chest pain, and decreased breath sounds on the affected side. However, it does not cause abdominal distension, acidosis, or hyperglycemia.
Choice B reason: Pulmonary embolism is a condition where a blood clot blocks one or more pulmonary arteries, causing impaired gas exchange and reduced blood flow to the lungs. It can cause respiratory distress, hypoxia, chest pain, and tachycardia. However, it does not cause abdominal distension, acidosis, or hyperglycemia.
Choice C reason: Abdominal compartment syndrome is a condition where increased intra-abdominal pressure causes reduced blood flow to the abdominal organs and impaired diaphragm movement. It can cause respiratory distress, hypoxia, abdominal distension, acidosis, decreased urine output, and organ failure. It is a common complication of cirrhosis with ascites.
Choice D reason: Sepsis is a condition where a systemic inflammatory response to an infection causes organ dysfunction and hypoperfusion. It can cause respiratory distress, hypoxia, fever or hypothermia, tachycardia, acidosis, and hyperglycemia. However, it does not cause abdominal distension unless there is an intra-abdominal infection.
The two actions the nurse should take to address abdominal compartment syndrome are:
- Prepare the client for a paracentesis: Paracentesis is a procedure where a needle or catheter is inserted into the peritoneal cavity to drain excess fluid and reduce intra-abdominal pressure.
- Place an intravenous line to start fluid boluses: Fluid boluses are given to maintain adequate blood pressure and perfusion to the vital organs.
The two parameters the nurse should monitor to assess the client’s progress are:
- Oxygen saturation: Oxygen saturation reflects the amount of oxygen bound to hemoglobin in the blood. It should be maintained above 90% to ensure adequate oxygen delivery to the tissues.
- Urine output: Urine output reflects the function of the kidneys and the perfusion of the renal arteries. It should be maintained above 0.5 mL/kg/hour to prevent acute kidney injury and electrolyte imbalances.
Correct Answer is A
Explanation
Choice A reason: This is correct because performing a bedside pregnancy test is the intervention that should be implemented immediately by the nurse. This is to confirm or rule out pregnancy and inform the surgical team of any possible risks or complications that may affect the client or the fetus.
Choice B reason: This is incorrect because continuing with surgery as scheduled is not an appropriate intervention without verifying the pregnancy status of the client. Surgery may pose serious threats to both maternal and fetal health, such as bleeding, infection, anesthesia complications, or miscarriage.
Choice C reason: This is incorrect because calculating gestation from last menstrual cycle is not an accurate or reliable method of determining pregnancy. The menstrual cycle can vary widely among women and may be affected by various factors such as stress, illness, or medication.
Choice D reason: This is incorrect because notifying the surgical team to cancel the surgery is not a necessary intervention unless pregnancy is confirmed. Appendicitis is a medical emergency that requires prompt surgical treatment to prevent rupture, peritonitis, or sepsis.
