1. What is an expected outcome when a client is receiving an IV administration of furosemide?
- A. Increased blood pressure.
- B. Increased urine output.
- C. Decreased pain.
- D. Decreased premature ventricular contractions.
Correct answer: B
Rationale: The correct answer is B: Increased urine output. Furosemide is a loop diuretic that works by inhibiting the reabsorption of sodium and chloride in the ascending loop of Henle in the kidneys, leading to increased urine production. This diuretic effect helps to reduce fluid volume in the body, making it an expected outcome when a client is receiving furosemide. Choice A, increased blood pressure, is incorrect because furosemide typically causes a decrease in blood pressure due to its diuretic effect. Choice C, decreased pain, and choice D, decreased premature ventricular contractions, are unrelated to the pharmacological action of furosemide.
2. A client admitted to the hospital with a diagnosis of acute pancreatitis has blood drawn for several serum laboratory tests. Which of the following serum amylase values, noted by the nurse reviewing the results, would be expected in this client at this time?
- A. 48 units/L
- B. 97 units/L
- C. 150 units/L
- D. 395 units/L
Correct answer: D
Rationale: The correct answer is D: "395 units/L." The normal serum amylase range is 25 to 151 units/L. In acute pancreatitis, the amylase level is greatly increased, typically exceeding the upper limit of the normal range. Choices A, B, and C fall within the normal range of serum amylase levels and would not be expected in a client with acute pancreatitis.
3. Why is the combination drug trimethoprim-sulfamethoxazole (TMP-SMX) necessary?
- A. To broaden the antibacterial spectrum.
- B. To decrease bacterial resistance.
- C. To improve the taste.
- D. To minimize toxic effects.
Correct answer: B
Rationale: The correct answer is B: To decrease bacterial resistance. Trimethoprim-sulfamethoxazole (TMP-SMX) is a combination drug used to prevent bacterial resistance to sulfonamides. It works by targeting different steps in the bacterial metabolic pathway, making it harder for bacteria to develop resistance. Choice A is incorrect because the combination does not broaden the antibacterial spectrum; instead, it enhances effectiveness against specific bacteria. Choice C is incorrect as taste improvement is not the primary reason for combining these drugs. Choice D is incorrect because while combination therapy can sometimes help minimize toxic effects, the primary purpose in this case is to address bacterial resistance.
4. The client with chronic renal failure is being educated on dietary restrictions. Which of the following foods should the client avoid?
- A. Bananas.
- B. Oranges.
- C. Rice.
- D. Apples.
Correct answer: A
Rationale: The correct answer is A: Bananas. Bananas are high in potassium, and clients with chronic renal failure are often advised to follow a low-potassium diet to prevent hyperkalemia. Oranges and apples are also high in potassium and should be avoided by clients with renal issues. Rice, on the other hand, is low in potassium and is generally considered safe for individuals with chronic renal failure to consume in moderation.
5. A client with chronic renal failure is receiving sodium polystyrene sulfonate (Kayexalate). The nurse should monitor the client for which of the following?
- A. Hyponatremia.
- B. Hypokalemia.
- C. Hyperkalemia.
- D. Hypocalcemia.
Correct answer: C
Rationale: Correct Answer: The correct answer is C, 'Hyperkalemia.' Sodium polystyrene sulfonate (Kayexalate) is a medication used to treat high potassium levels (hyperkalemia) by exchanging sodium ions for potassium ions in the intestines, leading to potassium removal from the body. Therefore, the nurse should monitor the client for changes in potassium levels to assess the effectiveness of the medication and prevent potential complications related to hyperkalemia. Choice A, 'Hyponatremia,' is incorrect as Kayexalate does not primarily affect sodium levels. Choice B, 'Hypokalemia,' is incorrect as Kayexalate is used to treat high potassium levels, not low. Choice D, 'Hypocalcemia,' is incorrect as Kayexalate does not directly impact calcium levels.
