ATI Fluid Electrolyte and Acid-Base Regulation Questions

Question 1 of 5

You are the nurse caring for a patient who is to receive IV daunorubicin, a chemotherapeutic agent. You start the infusion and check the insertion site as per protocol. During your most recent check, you note that the IV has infiltrated so you stop the infusion. What is your main concern with this infiltration?

Correct Answer: A

Rationale: The correct answer is A: Extravasation of the medication. Extravasation occurs when the infused medication leaks into surrounding tissues, potentially causing tissue damage and necrosis. This is a serious concern with vesicant medications like daunorubicin. If left untreated, it can lead to severe complications. Choice B: Discomfort to the patient is incorrect because while discomfort may occur with infiltration, the main concern is the potential for tissue damage from extravasation. Choice C: Blanching at the site is incorrect as it is a common sign of infiltration, but the main concern is the possibility of extravasation and tissue damage. Choice D: Hypersensitivity reaction to the medication is incorrect as it is a different type of reaction that is not directly related to infiltration or extravasation.

Question 2 of 5

You are doing discharge teaching with a patient who has hypophosphatemia during his time in hospital. The patient has a diet ordered that is high in phosphate. What foods would you teach this patient to include in his diet? Select all that do not apply

Correct Answer: B

Rationale: The correct answer is B: Beef. While beef is a good source of protein, it is not high in phosphate. Milk, poultry, and liver are high in phosphate and would be beneficial for a patient with hypophosphatemia. Beef is not typically a significant source of phosphate and therefore would not be as effective in increasing phosphate levels in the body compared to the other options. It is important for the patient to focus on consuming foods that are high in phosphate to help correct the hypophosphatemia.

Question 3 of 5

A nurse is caring for a client who is having a subclavian central venous catheter inserted. The client begins to report chest pain and difficulty breathing. After administering oxygen, which action should the nurse take next?

Correct Answer: B

Rationale: The correct answer is B: Prepare to assist with chest tube insertion. Chest pain and difficulty breathing after subclavian central venous catheter insertion could indicate a pneumothorax, a potential complication. Chest tube insertion is indicated to help re-expand the lung and relieve the pressure in the thoracic cavity. This intervention takes priority over the other options because it addresses the potential life-threatening complication of a pneumothorax. Administering nitroglycerin (choice A) is not indicated for chest pain in this scenario. Placing a sterile dressing over the IV site (choice C) is not appropriate for managing chest pain and difficulty breathing. Re-positioning the client into the Trendelenburg position (choice D) is not effective in addressing a pneumothorax and may worsen the client's condition.

Question 4 of 5

A nurse assesses a client who is prescribed furosemide (Lasix) for hypertension. For which acid-base imbalance should the nurse assess to prevent complications of this therapy?

Correct Answer: D

Rationale: The correct answer is D: Metabolic alkalosis. Furosemide, a loop diuretic, can lead to potassium depletion and metabolic alkalosis due to excessive loss of chloride and hydrogen ions. The nurse should assess for signs of metabolic alkalosis such as confusion, muscle weakness, and dysrhythmias to prevent complications. Respiratory acidosis and alkalosis are not directly related to furosemide therapy. Metabolic acidosis is less likely due to furosemide's mechanism of action.

Question 5 of 5

You are an emergency-room nurse caring for a trauma patient. Your patient has the following arterial blood gas results: pH 7.26, PaCO2 28, HCO3 11 mEq/L. How would you interpret these results?

Correct Answer: D

Rationale: To interpret the given ABG results: 1. pH <7.35 indicates acidosis. 2. PaCO2 <35 indicates respiratory alkalosis. 3. HCO3 <22 indicates metabolic acidosis. Therefore, the ABG results show metabolic acidosis (low pH, low HCO3) with compensatory respiratory alkalosis (low PaCO2). This means the body is trying to compensate for the metabolic acidosis by decreasing PaCO2 through hyperventilation. Option D is correct. Options A, B, and C are incorrect as they do not align with the ABG results and the principles of acid-base balance.
