Question 1 of 5
A nurse is reviewing the laboratory test results from a client who has prerenal acute kidney injury (AKI). Which of the following electrolyte imbalances should the nurse expect?
Correct Answer: B
Rationale: Hyperkalemia, which is a high level of potassium in the blood, is a common electrolyte imbalance seen in prerenal AKI due to decreased kidney function and the inability to excrete potassium.
Question 2 of 5
A woman was brought to the emergency department of a hospital after she fell and hurt her left leg. She is noted to be tachycardic and tachypneic. Painkillers were administered to lessen her pain. Suddenly, she started complaining that she is still in pain and now experiencing muscle cramps, tingling, and paresthesia. Measurement of arterial blood gas reveals pH 7.6, PaO2 120 mm Hg, PaCO2 31 mm Hg, and HCO3 25 mmol/L. What does this mean?
Correct Answer: B
Rationale: The elevated pH and low PaCO2 indicate respiratory alkalosis, likely due to hyperventilation. The normal HCO3 suggests that there has been no renal compensation, hence 'uncompensated'.
Question 3 of 5
A nurse is assigned to care for a client diagnosed with autoimmune or idiopathic thrombocytopenic purpura (ITP). When reviewing the client's plan of care prior to caring for the client, the nurse should recognize that the priority concern in caring for the client is to monitor for:
Correct Answer: C
Rationale: Thrombocytopenia, or low platelet count, is the hallmark of ITP and the main concern for monitoring, as it increases the risk of bleeding and bruising.
Question 4 of 5
A nurse is assessing a client who has a left lower arm fracture. Which of the following findings indicates impaired venous return in the client's affected arm?
Correct Answer: C
Rationale: Increasing edema is a sign of impaired venous return as it indicates a buildup of fluid in the tissues, which can occur if the veins are not effectively returning blood to the heart.
Question 5 of 5
Mrs. Jamerson, who is in the post anesthesia care unit (PACU) following surgery, is difficult to arouse and demonstrates shallow breathing. The patient does not respond to any stimuli. The nurse assesses the patient and obtains arterial blood gas (ABG) measurements STAT. The ABG shows a pH of 7.10, PaCO2 of 70 mm Hg, and HCO3 of 24 mEq/L. What does this mean?
Correct Answer: B
Rationale: Respiratory Acidosis Uncompensated is indicated by an acidic pH under 7.35 and an elevated PaCO2 over 45 mmHg, with HCO3 in the normal range.
