Question 1 of 5
A client diagnosed with nephrolithiasis arrives at the clinic for a follow-up visit. The laboratory analysis of the stone that the client passed 1 week ago indicates that the stone is composed of calcium oxalate. On the basis of this analysis, the nurse should tell the client that it is best to avoid which food to minimize the risk of recurrence?
Correct Answer: D
Rationale: Many kidney stones are composed of calcium oxalate. Foods that raise urinary oxalate excretion and predispose to stone formation include spinach, rhubarb, strawberries, chocolate, wheat bran, nuts, beets, almonds, cashews, rhubarb, and tea. Pasta, lentils, and lettuce are not high in oxalates and are generally safe for clients with calcium oxalate stones.
Question 2 of 5
A client is having blood tests and has an elevated lymphocyte level. Based on knowledge of cellular components, what does the nurse know about these cells?
Correct Answer: C
Rationale: Lymphocytes are a type of white blood cells that play a crucial role in supporting the body's immune system. They are responsible for producing substances that protect the body against infections and foreign substances that could potentially harm the client. Lymphocytes consist of two main types: T cells, which are produced in the thymus, and B cells, which are produced in the lymphatic tissue.
Choice A is incorrect because histamine is mainly associated with basophils and mast cells, not lymphocytes.
Choice B is incorrect as phagocytosis is a function of other white blood cells such as neutrophils and macrophages.
Choice D is also incorrect as carrying hemoglobin and oxygen is a function of red blood cells, not lymphocytes.
Question 3 of 5
Mrs. O is seen for follow-up after an episode of acute pancreatitis. Her physician orders a serum amylase level and the result is 200 U/L. Which of the following is a potential cause of this result?
Correct Answer: D
Rationale: An elevated serum amylase level after pancreatitis may indicate another attack of the condition. It is common to order serum amylase as part of routine follow-up after pancreatitis. Elevated levels can also be seen in related gastrointestinal conditions like cholecystitis or an intestinal blockage.
Therefore, in this case, the most likely cause of the elevated serum amylase level is a recurrence or ongoing pancreatitis. The other options, including pregnancy, hypertension, and renal failure, are not typically associated with an elevated serum amylase level in the context of follow-up after acute pancreatitis.
Question 4 of 5
The nurse is assigned to care for a client being admitted with a diagnosis of cirrhosis and ascites. Which dietary measure should the nurse expect to be prescribed for the client?
Correct Answer: A
Rationale: If the client has ascites, sodium and possibly fluids would be restricted in the diet. The client should maintain a normal amount of fat intake. The diet should supply sufficient carbohydrates to maintain weight and spare protein. The total daily calories should range between 2000 and 3000 . The diet should provide ample protein to rebuild tissue but not an amount that will precipitate hepatic encephalopathy.
Question 5 of 5
A client with adrenal insufficiency has a potassium level of 7.2 mEq/L. Which of the following signs or symptoms might the client exhibit with this result?
Correct Answer: A
Rationale: A client with hyperkalemia may exhibit peaked T waves on an electrocardiogram. This manifestation is an early sign of high potassium levels, but diagnosis should not be based on this aspect alone. Untreated, hyperkalemia can lead to progressively worsening cardiac instability. Muscle spasms (
Choice
B) are more commonly associated with hypocalcemia. Constipation (
Choice
C) is not a typical sign of hyperkalemia. A prominent U wave on the ECG (
Choice
D) is associated with hypokalemia, not hyperkalemia.
