1. What is the function of aldosterone?
- A. Regulates body temperature.
 - B. Decreases blood pressure.
 - C. Increases sodium reabsorption.
 - D. Promotes water excretion.
 
Correct answer: C
Rationale: Aldosterone increases the reabsorption of sodium in the kidneys, which leads to an increase in blood volume and blood pressure. Choice A is incorrect as aldosterone does not regulate body temperature. Choice B is incorrect as aldosterone increases blood pressure by increasing sodium reabsorption. Choice D is incorrect as aldosterone promotes water retention by increasing sodium reabsorption.
2. The nurse who assesses the patient's peripheral IV site and notes edema around the insertion site will document which complication related to IV therapy?
- A. Air emboli
 - B. Phlebitis
 - C. Infiltration
 - D. Fluid overload
 
Correct answer: C
Rationale: Infiltration is the administration of non-vesicant solution or medication into the surrounding tissue. This can occur when the IV cannula dislodges or perforates the vein's wall. Infiltration is characterized by edema around the insertion site, leakage of IV fluid from the insertion site, discomfort, and coolness in the area of infiltration, and a significant decrease in the flow rate. Air emboli (Choice A) involves air entering the bloodstream. Phlebitis (Choice B) is inflammation of a vein. Fluid overload (Choice D) is an excessive volume of fluid in the circulatory system.
3. The nurse is caring for a patient in metabolic alkalosis. The patient has an NG tube to low intermittent suction for a diagnosis of bowel obstruction. What drug would the nurse expect to find on the medication orders?
- A. Cimetidine
 - B. Maalox
 - C. Potassium chloride elixir
 - D. ) Furosemide
 
Correct answer: A
Rationale:
4. A nurse evaluates a clients arterial blood gas values (ABGs): pH 7.30, PaO2 86 mm Hg, PaCO2 55 mm Hg, and HCO3 22 mEq/L. Which intervention should the nurse implement first?
- A. Assess the airway.
 - B. Administer prescribed bronchodilators.
 - C. Provide oxygen.
 - D. Administer prescribed mucolytics
 
Correct answer: A
Rationale:
5. While assessing clients on a medical-surgical unit, which client is at risk for hypokalemia?
- A. Client with pancreatitis who has continuous nasogastric suctioning
 - B. Client who is prescribed an angiotensin-converting enzyme (ACE) inhibitor
 - C. Client in a motor vehicle crash who is receiving 6 units of packed red blood cells
 - D. Client with uncontrolled diabetes and a serum pH level of 7.33
 
Correct answer: A
Rationale: Continuous nasogastric suctioning can lead to hypokalemia due to the loss of gastric contents rich in potassium. Therefore, a client with pancreatitis who has continuous nasogastric suctioning is at risk for hypokalemia. Option B is incorrect because ACE inhibitors may lead to hyperkalemia, not hypokalemia. Option C is incorrect as receiving packed red blood cells can lead to hyperkalemia due to the potassium content in the blood product. Option D is incorrect because a serum pH level of 7.33 indicates acidosis, which is not directly associated with hypokalemia.
