HESI Medical Surgical Specialty Exam
1. A client is brought to the emergency department by a neighbor. The client is lethargic and has a fruity odor on the breath. The client’s arterial blood gas (ABG) results are pH 7.25, PCO2 34 mm Hg, PO2 86 mm Hg, HCO3 14 mEq/L. Which of the following acid-base disturbances does the nurse recognize in these results?
- A. Metabolic acidosis
- B. Metabolic alkalosis
- C. Respiratory acidosis
- D. Respiratory alkalosis
Correct answer: A
Rationale: The correct answer is 'Metabolic acidosis.' Metabolic acidosis is characterized by a low pH (<7.35) and a low bicarbonate level (HCO3 <22 mEq/L). In this case, the client's ABG results show a pH of 7.25 and an HCO3 level of 14 mEq/L, indicating metabolic acidosis. The PCO2 of 34 mm Hg is normal, ruling out respiratory acidosis or alkalosis. The PO2 of 86 mm Hg is also within the normal range and is not indicative of a respiratory problem. Therefore, the client is experiencing metabolic acidosis based on the ABG results provided.
2. A client with cholelithiasis is admitted with jaundice due to obstruction of the common bile duct. Which finding is most important for the nurse to report to the healthcare provider?
- A. Distended, hard, and rigid abdomen
- B. Clay-colored stool
- C. Radiating sharp pain in the right shoulder
- D. Bile-stained emesis
Correct answer: A
Rationale: The most important finding for the nurse to report to the healthcare provider in a client with cholelithiasis and jaundice due to common bile duct obstruction is a distended, hard, and rigid abdomen. These signs may indicate a possible surgical emergency, such as a complication like gallbladder perforation or peritonitis, which require immediate intervention. Clay-colored stool is associated with obstructive jaundice but does not indicate an acute surgical emergency. Radiating sharp pain in the right shoulder (referred pain from the diaphragm) and bile-stained emesis may also be seen in cholelithiasis but are not as urgent as a distended, hard, and rigid abdomen.
3. A patient is being treated for shock after a motor vehicle accident. The provider orders 6% dextran 75 to be given intravenously. The nurse should expect which outcome as the result of this infusion?
- A. Decreased urine output
- B. Improved blood oxygenation
- C. Increased interstitial fluid
- D. Stabilization of heart rate and blood pressure
Correct answer: D
Rationale: 6% Dextran 75 is a high molecular-weight colloidal solution used to treat shock from burns or trauma. Colloids like 6% dextran 75 are plasma expanders that help increase blood volume, leading to improved heart rate and blood pressure stabilization. The infusion of plasma expanders does not typically decrease urine output. It primarily aims to stabilize circulation rather than affect blood oxygenation or increase interstitial fluid levels.
4. 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.
5. A client scheduled for the surgical creation of an ileal conduit expresses anxiety and asks about having a drainage tube. How should the nurse respond?
- A. I will ask the provider to prescribe you an antianxiety medication.
- B. Would you like to discuss the procedure with your doctor once more?
- C. I think it would be nice to not have to worry about finding a bathroom.
- D. Would you like to speak with someone who has an ileal conduit?
Correct answer: D
Rationale: The most appropriate response for the nurse is to offer the client the opportunity to speak with someone who has undergone the same procedure. This allows the client to gain insight, ask questions, and share concerns with someone who has firsthand experience, which can help alleviate anxiety and promote a positive self-image. Seeking an antianxiety medication does not address the client's emotional concerns or promote a positive attitude towards the procedure. Discussing the procedure with the doctor again may provide more information but may not offer the same level of emotional support and understanding as speaking with someone who has lived through the experience. Commenting on the convenience of not having to search for a bathroom minimizes the client's anxiety and overlooks the emotional aspect of the client's concerns.
