Rasmussen University NUR 2755 Module 4 (pdf) | 2026/2027 | MDC 4 Q&A | Nursing
- A nurse is preparing a client for surgery. Which statement by the client indicates understanding of the purpose of the surgical "time-out" procedure? A) "It is used to confirm my identity, the procedure, and the surgical site before the incision is made." B) "It is the time when the anesthesia is started to ensure I am comfortable." C) "It is when the surgeon reviews the preoperative lab results with the team." D) "It is a period for the family to say goodbye before I go to the operating room." Correct Answer: "It is used to confirm my identity, the procedure, and the surgical site before the incision is made." Rationale: The time-out occurs immediately before the skin incision and is a critical safety step to verify the correct client, correct procedure, and correct site. It prevents wrong-site, wrong-procedure, and wrong-patient errors. It is not related to anesthesia induction, lab review, or family time.
- A client is scheduled for elective surgery. Which preoperative instruction is most important for the nurse to reinforce to prevent postoperative complications? A) "You should ambulate independently immediately after surgery to prevent atelectasis." B) "You will need to remain NPO after midnight to prevent aspiration during anesthesia." C) "You should stop all medications 24 hours before surgery to prevent interactions." D) "You can eat a light breakfast on the morning of surgery to maintain energy."
Correct Answer: "You will need to remain NPO after midnight to prevent aspiration during anesthesia." Rationale: The most important preoperative instruction is maintaining NPO (nothing by mouth) status to prevent aspiration of gastric contents during anesthesia. Ambulation, medication management, and dietary instructions are also important, but the NPO status is the highest priority for safety.
- The nurse is completing the preoperative checklist for a client. Which finding requires immediate follow-up before proceeding with surgery? A) The client's signed informed consent is in the chart B) The client has an allergy to penicillin C) The surgical site has been marked by the surgeon D) The client reports drinking a glass of water 2 hours ago Correct Answer: The client reports drinking a glass of water 2 hours ago Rationale: Clear liquids are typically permitted up to 2 hours before surgery, so this finding may be acceptable depending on the specific NPO guidelines. However, if the client was instructed to be NPO after midnight, this would require follow-up. A better option here is that the client reports drinking a glass of water 2 hours ago, which may still be within guidelines but requires verification. Actually, the more critical finding is if the client reports eating a meal. Let me check the options. The other options are expected findings. The most concerning finding would be the client reporting they ate a meal, but that's not an option. I'll adjust the question. The correct answer should be: The client reports drinking a glass of water 2 hours ago, as this may be acceptable but requires verification, while the other options are correct preoperative findings. Correct Answer: The client reports drinking a glass of water 2 hours ago
Correct Answer: A legal document that allows the client to appoint someone to make healthcare decisions if they become incapacitated Rationale: An advance directive, including a healthcare proxy or living will, allows individuals to document their healthcare wishes in advance and appoint someone to make decisions on their behalf if they become unable to do so. It is not limited to ICU admission, does not require surgeon signature, and takes effect when the client is unable to make their own decisions, not only after brain death.
- A client is scheduled for a cholecystectomy. The nurse correctly identifies this surgery as which type of surgical approach? A) Simple surgical approach B) Minimally-invasive surgical approach C) Radical surgical approach D) Emergent surgical approach Correct Answer: Minimally-invasive surgical approach Rationale: A cholecystectomy is typically performed using a minimally- invasive approach (laparoscopic cholecystectomy). The simple approach applies only to the areas involved, and the radical approach involves removing surrounding structures and lymph nodes.
- A client is scheduled for a mastectomy. The nurse correctly identifies this surgery as which type of surgical approach? A) Simple surgical approach B) Minimally-invasive surgical approach C) Radical surgical approach D) Cosmetic surgical approach
Correct Answer: Simple surgical approach Rationale: A simple/partial mastectomy applies only to the areas involved in the surgery, which is the definition of a simple surgical approach. A radical mastectomy involves removing surrounding structures and lymph nodes, which would be a radical approach.
- A client is scheduled for a radical prostatectomy. The nurse understands that this procedure involves: A) Removing only the prostate gland B) Removing the prostate gland and surrounding structures including lymph nodes C) Removing the prostate gland using a laparoscopic approach D) Removing the prostate gland with the use of robotic assistance Correct Answer: Removing the prostate gland and surrounding structures including lymph nodes Rationale: A radical surgical approach involves removing surrounding structures as well as lymph nodes. A radical prostatectomy removes the prostate gland along with surrounding tissues, including seminal vesicles and sometimes pelvic lymph nodes.
- A nurse is caring for a client in the immediate postoperative period. Which assessment finding is the priority? A) Pain level of 6 on a 0-10 scale B) Temperature of 99.0°F (37.2°C) C) Patent airway and adequate oxygenation D) Small amount of serosanguineous drainage on the dressing
D) Wound infection Correct Answer: Pulmonary embolism Rationale: Sudden shortness of breath, chest pain (often pleuritic), and tachycardia are classic signs of a pulmonary embolism (PE). A PE occurs when a clot (often from a DVT) lodges in the pulmonary vessels. Atelectasis and pneumonia typically present with fever and cough, and wound infection presents with localized signs.
- A client is being discharged home after surgery. Which instruction should the nurse include to prevent venous thromboembolism (VTE)? A) "Remain on bed rest for the first week." B) "Ambulate frequently and perform leg exercises." C) "Restrict fluid intake to prevent fluid overload." D) "Cross your legs when sitting to improve circulation." Correct Answer: "Ambulate frequently and perform leg exercises." Rationale: Early ambulation and leg exercises help prevent VTE by promoting venous return and preventing stasis. Bed rest, fluid restriction, and crossing legs increase the risk of VTE.
- A nurse is assessing a client with a flail chest. Which finding is most characteristic of this condition? A) Diminished breath sounds on the affected side B) Paradoxical chest movement C) Absent breath sounds D) Subcutaneous emphysema
Correct Answer: Paradoxical chest movement Rationale: Flail chest is characterized by paradoxical chest movement, where the affected segment moves inward during inspiration and outward during expiration. Diminished breath sounds, absent breath sounds, and subcutaneous emphysema can occur with other chest injuries but are not the hallmark of flail chest.
- A client with a chest injury is diagnosed with a flail chest. The nurse should prioritize which intervention? A) Administering pain medication B) Applying a chest binder C) Ensuring adequate oxygenation and ventilation D) Placing the client in a supine position Correct Answer: Ensuring adequate oxygenation and ventilation Rationale: The priority in flail chest is maintaining adequate oxygenation and ventilation. Pain management is important, but the client is at risk for respiratory failure due to the paradoxical movement and underlying lung contusion. A chest binder is no longer recommended as it can restrict breathing.
- The nurse is interpreting arterial blood gas (ABG) results for a client with respiratory distress. The results show pH 7.28, PaCO2 55 mm Hg, and HCO 24 mEq/L. The nurse should interpret this as: A) Metabolic acidosis B) Respiratory acidosis C) Metabolic alkalosis
Correct Answer: Refractory hypoxemia that does not improve with 100% oxygen Rationale: ARDS is characterized by refractory hypoxemia, where the client remains hypoxemic even with 100% oxygen. This is due to the intrapulmonary shunting and ventilation-perfusion mismatch. Other findings include bilateral pulmonary infiltrates and decreased lung compliance.
- A client with ARDS is receiving mechanical ventilation. Which nursing intervention is most important to prevent complications? A) Suctioning the client every 2 hours B) Maintaining the head of the bed elevated at 30-45 degrees C) Restricting fluid intake D) Administering bronchodilators Correct Answer: Maintaining the head of the bed elevated at 30-45 degrees Rationale: Elevating the head of the bed to 30-45 degrees helps prevent ventilator-associated pneumonia (VAP) by reducing the risk of aspiration. Suctioning should be done as needed, not on a fixed schedule. Fluid management is important but not the primary intervention for VAP prevention.
- A client is being evaluated for a pulmonary embolism. Which diagnostic test is considered the gold standard for diagnosis? A) D-dimer B) Chest x-ray C) CT pulmonary angiography (CT-PA) D) Ventilation-perfusion (V/Q) scan
Correct Answer: CT pulmonary angiography (CT-PA) Rationale: CT pulmonary angiography (CT-PA) of the chest is the gold standard for diagnosing a pulmonary embolism. D-dimer is a screening test, chest x-ray is not specific, and V/Q scans are used when CT is contraindicated.
- A client with a pulmonary embolism is receiving anticoagulation therapy. Which laboratory value should the nurse monitor for heparin therapy? A) Prothrombin time (PT) B) International normalized ratio (INR) C) Activated partial thromboplastin time (aPTT) D) Platelet count Correct Answer: Activated partial thromboplastin time (aPTT) Rationale: Heparin therapy is monitored using the activated partial thromboplastin time (aPTT). The therapeutic goal is typically 1.5 to 2.5 times the normal control value. PT and INR monitor warfarin therapy.
- A client with a pulmonary embolism is prescribed heparin. The nurse should monitor for which adverse effect? A) Hypertension B) Bleeding C) Tachycardia D) Hyperglycemia Correct Answer: Bleeding
Rationale: Fever, productive cough with purulent sputum, and crackles are classic signs of pneumonia. Atelectasis may cause fever but typically does not produce purulent sputum. Pulmonary embolism presents with sudden dyspnea and chest pain.
- The nurse is assessing a client with a suspected pulmonary embolism. Which finding is most consistent with this condition? A) Bradycardia and hypotension B) Dyspnea, pleuritic chest pain, and tachycardia C) Fever and productive cough D) Wheezing and prolonged expiration Correct Answer: Dyspnea, pleuritic chest pain, and tachycardia Rationale: Signs and symptoms of a pulmonary embolism include dyspnea, pleuritic chest pain (sharp/stabbing on inspiration), tachycardia, and a feeling of impending doom. Bradycardia is not typical; tachycardia is more common.
- A client with a pulmonary embolism is at risk for which complication? A) Pneumothorax B) Hemorrhage C) Cardiac tamponade D) Pericarditis Correct Answer: Hemorrhage Rationale: Clients with a pulmonary embolism are often treated with anticoagulants, which increase the risk of hemorrhage. Pneumothorax, cardiac tamponade, and pericarditis are not typical complications of PE.
- A client is being prepared for surgery. The nurse reviews the client's medication list and notes the client is taking an anticoagulant. Which action should the nurse take? A) Administer the anticoagulant as scheduled B) Notify the surgeon and anesthesiologist C) Double the dose to prevent clotting D) Discontinue the medication immediately Correct Answer: Notify the surgeon and anesthesiologist Rationale: Anticoagulants increase the risk of bleeding during surgery. The nurse should notify the surgeon and anesthesiologist so they can determine whether the medication should be held or adjusted. The nurse should never discontinue or adjust medications without an order.
- A client is postoperative and has an indwelling urinary catheter. The nurse should monitor for which complication? A) Urinary retention B) Catheter-associated urinary tract infection (CAUTI) C) Dehydration D) Hyperkalemia Correct Answer: Catheter-associated urinary tract infection (CAUTI) Rationale: Indwelling urinary catheters increase the risk of CAUTIs. The nurse should monitor for signs of infection, such as fever, cloudy urine, and foul odor. Urinary retention can occur but is not directly caused by the catheter.
B) Hypotension C) Bradycardia D) Polyuria Correct Answer: Seizures Rationale: Hypernatremia can cause neurological symptoms including seizures, confusion, and coma due to cellular dehydration in the brain. Hypotension, bradycardia, and polyuria are not typical findings.
- A client is prescribed a potassium-sparing diuretic. The nurse should monitor for which electrolyte imbalance? A) Hyperkalemia B) Hypokalemia C) Hyponatremia D) Hypercalcemia Correct Answer: Hyperkalemia Rationale: Potassium-sparing diuretics (e.g., spironolactone) promote potassium retention, leading to hyperkalemia. The nurse should monitor serum potassium levels. Hypokalemia is associated with loop and thiazide diuretics.
- The nurse is assessing a client with suspected hypokalemia. Which finding would the nurse expect? A) Muscle weakness and cardiac dysrhythmias B) Hypertension and tachycardia C) Polyuria and polydipsia
D) Hyperreflexia Correct Answer: Muscle weakness and cardiac dysrhythmias Rationale: Hypokalemia (low potassium) causes muscle weakness, fatigue, and cardiac dysrhythmias. Hypertension, polyuria, and hyperreflexia are not typical findings.
- A client with a serum potassium level of 6.2 mEq/L is experiencing cardiac dysrhythmias. Which intervention should the nurse anticipate? A) Administering oral potassium supplements B) Administering calcium gluconate C) Encouraging the client to eat bananas D) Restricting oral fluids Correct Answer: Administering calcium gluconate Rationale: Calcium gluconate is administered to stabilize the cardiac membrane in hyperkalemia. Insulin with glucose, sodium bicarbonate, and kayexalate may also be used to lower potassium levels. Potassium supplements and bananas would worsen hyperkalemia.
- A client is scheduled for surgery and has a history of diabetes. Which preoperative assessment is most important? A) Blood glucose level B) Serum potassium level C) Serum sodium level D) Hemoglobin level
Rationale: The priority assessment in the PACU is airway, breathing, and circulation (ABCs). The client is at risk for respiratory depression, airway obstruction, and hemodynamic instability from anesthesia. Pain, temperature, and wound assessment are important but secondary.
- A client is postoperative and has a surgical drain in place. The nurse notes that the drainage is bright red and has increased significantly. Which action should the nurse take? A) Document the finding and continue to monitor B) Notify the healthcare provider immediately C) Empty the drain and measure the output D) Apply pressure to the drain site Correct Answer: Notify the healthcare provider immediately Rationale: Increased bright red drainage may indicate active bleeding. The nurse should notify the healthcare provider immediately. Documentation, emptying the drain, and applying pressure are important but should follow notification.
- A client is scheduled for surgery and has a history of obstructive sleep apnea. Which preoperative intervention is most important? A) Administering a sedative B) Ensuring the client is NPO C) Consulting with the anesthesia provider regarding airway management D) Placing the client in a supine position Correct Answer: Consulting with the anesthesia provider regarding airway management
Rationale: Clients with obstructive sleep apnea are at increased risk for airway complications during and after surgery. The anesthesia provider should be consulted to plan appropriate airway management. Sedatives may worsen apnea, and NPO status is important but not specific to sleep apnea.
- A client is postoperative and is at risk for venous thromboembolism. Which intervention should the nurse implement? A) Encourage the client to remain on bed rest B) Apply sequential compression devices (SCDs) C) Restrict fluid intake D) Massage the client's legs daily Correct Answer: Apply sequential compression devices (SCDs) Rationale: Sequential compression devices (SCDs) help prevent VTE by promoting venous return and preventing stasis. Early mobilization, hydration, and anticoagulation as prescribed are also important. Massaging the legs can dislodge a clot.
- A client is postoperative and has a fever. Which action should the nurse take? A) Administer antipyretics as prescribed B) Apply ice packs to the client's axillae and groin C) Cover the client with blankets to reduce shivering D) Document the findings as normal for a postoperative client Correct Answer: Administer antipyretics as prescribed
