A client with chronic renal failure is being treated with 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: The correct answer is C: Hyperkalemia. Sodium polystyrene sulfonate (Kayexalate) is used to treat high potassium levels (hyperkalemia) by exchanging sodium ions for potassium ions in the large intestine, which is then eliminated through the feces. Therefore, the nurse should monitor the client for changes in potassium levels to ensure the effectiveness of the treatment. Choices A, B, and D are incorrect because sodium polystyrene sulfonate (Kayexalate) is not associated with causing hyponatremia, hypokalemia, or hypocalcemia.

The client with chronic renal failure is being taught about the importance of fluid restrictions. Which of the following statements by the client indicates that the teaching has been effective?
- A. I can drink as much fluid as I want, as long as I take my medication.
- B. I will need to limit my fluid intake to prevent fluid overload.
- C. I can drink as much water as I want, as long as I limit other fluids.
- D. I will need to drink only when I am thirsty.
Correct Answer: B
Rationale: The correct answer is B: 'I will need to limit my fluid intake to prevent fluid overload.' In chronic renal failure, fluid restrictions are crucial to prevent fluid overload and further damage to the kidneys. Option A is incorrect as unrestricted fluid intake can worsen the condition. Option C is also incorrect as total fluid intake needs to be restricted, not just other fluids. Option D is not ideal because thirst may not accurately reflect the body's fluid needs in chronic renal failure.
Which of the following conditions is most commonly associated with a high risk of stroke?
- A. Hypertension.
- B. Diabetes.
- C. Obesity.
- D. Smoking.
Correct Answer: A
Rationale: Hypertension is the correct answer. Hypertension, also known as high blood pressure, is a major risk factor for stroke because it puts increased pressure on blood vessels in the brain, making them more prone to damage and increasing the likelihood of a stroke. While diabetes, obesity, and smoking are also risk factors for stroke, hypertension is the most commonly associated condition with a high risk of stroke due to its direct impact on the blood vessels.
In a patient with liver cirrhosis, which of the following lab results would be expected?
- A. Increased bilirubin levels.
- B. Decreased albumin levels.
- C. Increased liver enzymes.
- D. Decreased platelet count.
Correct Answer: A
Rationale: In a patient with liver cirrhosis, increased bilirubin levels would be expected. Liver cirrhosis leads to impaired liver function, causing a decrease in the liver's ability to process bilirubin, leading to its accumulation in the blood. This results in elevated bilirubin levels. Decreased albumin levels (choice B) may occur in liver cirrhosis due to impaired liver synthesis of proteins, but it is not as specific as increased bilirubin levels. Increased liver enzymes (choice C) can be seen in liver damage but are not as characteristic as elevated bilirubin levels. Decreased platelet count (choice D) can occur in liver cirrhosis due to hypersplenism, but it is not as specific as increased bilirubin levels in this context.
A client has had a pulmonary artery catheter inserted. In performing hemodynamic monitoring with the catheter, the nurse will wedge the catheter to gain information about which of the following?
- A. Cardiac output.
- B. Right atrial blood flow.
- C. Left end-diastolic pressure.
- D. Cardiac index.
Correct Answer: C
Rationale: The correct answer is C: Left end-diastolic pressure. Wedging the pulmonary artery catheter allows the nurse to obtain the pulmonary artery wedge pressure, which reflects the left end-diastolic pressure. This pressure is essential in assessing left ventricular function and diagnosing conditions like heart failure. Choices A, B, and D are incorrect because wedging the catheter does not directly provide information about cardiac output, right atrial blood flow, or cardiac index.
What is the primary nursing intervention for a patient experiencing an acute asthma attack?
- A. Administering bronchodilators.
- B. Administering antibiotics.
- C. Administering IV fluids.
- D. Administering corticosteroids.
Correct Answer: A
Rationale: The correct answer is administering bronchodilators. During an acute asthma attack, the primary goal is to relieve airway constriction and bronchospasm to improve breathing. Bronchodilators, such as short-acting beta-agonists, are the cornerstone of treatment as they help dilate the airways quickly. Administering antibiotics (choice B) is not indicated unless there is an underlying bacterial infection. Administering IV fluids (choice C) may be necessary in some cases, but it is not the primary intervention for an acute asthma attack. Administering corticosteroids (choice D) is often used as an adjunct therapy to reduce airway inflammation, but it is not the primary intervention during the acute phase of an asthma attack.
