NCLEX Med Surg Practice Questions with Answers

Preparing for the NCLEX-RN requires a deep understanding of Medical-Surgical nursing, which typically comprises the largest portion of the exam. This guide provides high-quality NCLEX Med Surg practice questions with answers to help you master complex patient care scenarios, prioritize interventions, and develop the clinical judgment necessary for success. By reviewing these concepts, you will be better equipped to handle the physiological integrity domain of the licensure examination.

Concept Explanation

Medical-Surgical nursing is a specialized area of practice that focuses on the care of adult patients who are acutely ill, recovering from surgery, or managing chronic medical conditions. It involves the application of the nursing process—assessment, diagnosis, planning, implementation, and evaluation—to manage a wide array of body system disorders, ranging from cardiovascular and respiratory issues to endocrine and gastrointestinal pathologies. Effective med-surg nursing requires a strong grasp of pathophysiology, pharmacology, and dosage calculation to ensure patient safety. According to the National Council of State Boards of Nursing (NCSBN), candidates must demonstrate the ability to provide care for patients with multi-system failures and complex needs. Success in this area relies on your ability to prioritize care using frameworks like Maslow’s Hierarchy of Needs and the ABCs (Airway, Breathing, Circulation).

Solved Examples

Review these worked examples to understand how to approach complex med-surg scenarios on the exam.

1. Scenario: A patient with chronic obstructive pulmonary disease (COPD) is receiving oxygen via nasal cannula at 2 L/min. The nurse notes the patient's oxygen saturation is 89% and they are slightly short of breath. What is the priority action?
   • Step 1: Assess the patient's baseline. Patients with COPD often have a target SpO2 of 88%–92%.
   • Step 2: Evaluate the current intervention. 2 L/min is a standard low-flow rate for COPD to avoid suppressing the hypoxic drive.
   • Step 3: Determine if the situation is an emergency. 89% is within the acceptable range for this specific population.
   • Solution: Continue to monitor the patient and encourage pursed-lip breathing. Do not increase oxygen rapidly without a provider's order.
2. Scenario: A postoperative patient has a blood pressure of 90/50 mmHg and a heart rate of 120 bpm. The surgical site dressing is saturated with bright red blood.
   • Step 1: Identify the clinical signs. Tachycardia and hypotension indicate potential hypovolemic shock.
   • Step 2: Identify the source. Saturated bright red blood indicates active hemorrhage.
   • Step 3: Prioritize intervention. The first action is to stop the bleeding.
   • Solution: Apply direct pressure to the surgical site and notify the surgeon immediately while preparing for fluid resuscitation.
3. Scenario: A patient is diagnosed with Type 1 Diabetes and is found sweaty, shaky, and confused.
   • Step 1: Recognize symptoms of hypoglycemia (shakiness, diaphoresis, confusion).
   • Step 2: Check blood glucose levels if a glucometer is immediately available.
   • Step 3: Treat based on the "Rule of 15" if the patient is conscious.
   • Solution: Administer 15g of rapid-acting carbohydrates (e.g., 4 oz orange juice) and recheck in 15 minutes.

Practice Questions

Test your knowledge with these NCLEX Med Surg practice questions with answers. These questions cover various body systems and nursing interventions.

1. A nurse is caring for a patient who is 24 hours post-thyroidectomy. The patient reports tingling in the fingers and around the mouth. Which action should the nurse take first?

2. A patient with a history of heart failure presents with a weight gain of 5 lbs in two days, crackles in the lung bases, and peripheral edema. Which medication does the nurse expect the provider to order?

3. Following a total hip arthroplasty, which position should the nurse maintain for the patient's affected extremity to prevent dislocation?

4. A nurse is assessing a patient with a chest tube. The nurse notes continuous bubbling in the water-seal chamber. How should the nurse interpret this finding?

5. A patient is admitted with suspected appendicitis. Which of the following nursing interventions is contraindicated for this patient?

6. An elderly patient is prescribed a high dose of a loop diuretic. The nurse should monitor for which electrolyte imbalance most closely?

7. A patient with a head injury has a Glasgow Coma Scale (GCS) score of 7. What is the priority nursing action for this patient?

8. A patient is receiving a blood transfusion and starts complaining of lower back pain and chills. What is the immediate priority?

9. A patient with deep vein thrombosis (DVT) is on a heparin infusion. The nurse notes the aPTT is 110 seconds (Control: 30 seconds). What is the appropriate action?

10. Which clinical manifestation would the nurse expect to find in a patient with Graves' disease (hyperthyroidism)?

Answers & Explanations

1. Answer: Assess for Trousseau's or Chvostek's sign. Tingling (paresthesia) after a thyroidectomy suggests hypocalcemia, often due to accidental removal or damage to the parathyroid glands. The nurse must assess for neuromuscular irritability.
2. Answer: Furosemide (Lasix). The symptoms (weight gain, crackles, edema) indicate fluid volume excess and pulmonary congestion. Loop diuretics are the standard treatment for acute heart failure exacerbations. For more on this drug class, see cardiovascular practice questions.
3. Answer: Abduction. To prevent dislocation of a new hip prosthesis, the hip should be kept in an abducted position, often using an abduction pillow, and flexion should be limited to less than 90 degrees.
4. Answer: An air leak in the system. Intermittent bubbling in the water-seal chamber is normal during expiration or coughing, but continuous bubbling indicates a leak between the patient and the water seal.
5. Answer: Application of a heating pad to the abdomen. Heat increases vascular flow and can lead to the rupture of an inflamed appendix, causing peritonitis. Cold packs are generally safer if needed for comfort.
6. Answer: Hypokalemia. Loop diuretics promote the excretion of potassium. Low potassium can lead to life-threatening cardiac arrhythmias. You can practice related calculations using our IV flow rate practice tools.
7. Answer: Prepare for endotracheal intubation. A GCS score of 8 or less typically indicates that the patient cannot maintain their own airway or protect it from aspiration ("Less than 8, intubate").
8. Answer: Stop the transfusion immediately. Low back pain and chills are classic signs of a hemolytic transfusion reaction. The nurse must stop the blood, disconnect the tubing at the hub, and run normal saline with new tubing.
9. Answer: Stop the infusion and prepare protamine sulfate. The therapeutic range for aPTT is usually $1.5 \times$ to $2.5 \times$ the control. A value of 110 seconds is significantly above the therapeutic range (which would be 45-75s), putting the patient at high risk for hemorrhage.
10. Answer: Exophthalmos and heat intolerance. Graves' disease is characterized by hypermetabolism. Symptoms include bulging eyes (exophthalmos), weight loss, tachycardia, and an inability to tolerate heat.

Quick Quiz

Frequently Asked Questions

What are the most common Med Surg topics on the NCLEX?

The NCLEX heavily emphasizes cardiovascular health, respiratory management, endocrine disorders (especially diabetes), and perioperative care. Prioritization and delegation within these topics are frequently tested to ensure the candidate can manage a typical medical-surgical floor safely.

How do I prioritize patients in Med Surg questions?

Use the ABC framework—Airway, Breathing, and Circulation—as your primary guide for stability. If all patients are stable, use Maslow’s Hierarchy of Needs to prioritize physiological needs over safety or psychosocial needs, and always address acute changes before chronic conditions.

What is the "Rule of 9s" in Med Surg nursing?

The Rule of 9s is a standardized method used to estimate the total body surface area (TBSA) affected by burns in an adult. It divides the body into sections of 9% (or multiples thereof) to guide fluid resuscitation using formulas like the Parkland Formula. For practice with these specific calculations, you can use our BSA-based calculation practice.

Why is potassium monitoring so important in Med Surg?

Potassium is a critical intracellular cation that regulates cardiac rhythm and nerve impulse transmission. Both hyperkalemia and hypokalemia can lead to lethal cardiac arrhythmias, making it a high-priority lab value in patients taking diuretics, those with renal failure, or those in ketoacidosis.

How can I improve my clinical judgment for the NCLEX?

Improving clinical judgment involves practicing with realistic case studies and focusing on the "why" behind nursing interventions. Utilizing tools like an AI Exam Simulator can help you get used to the decision-making pressure of the actual exam.

What is the difference between a side effect and an adverse effect?

A side effect is a predictable, often unavoidable secondary effect of a drug at therapeutic doses, whereas an adverse effect is an unintended, undesirable, and often unpredictable response that may occur at normal doses. For more practice on this, check out our adverse effect practice questions.
