Free Orthopedic Nursing Certification Practice Sample Questions & Answers

Question 1. A patient with a tibial fracture in a long-leg cast reports that the pain has suddenly become severe despite receiving prescribed analgesia. The toes are cool, and the patient reports increasing numbness. What should the nurse do first?

A. Elevate the affected leg above the level of the heart

B. Apply an additional ice pack over the cast

C. Perform an immediate neurovascular assessment and notify the provider

D. Encourage the patient to move the toes repeatedly

Correct Answer. C. Perform an immediate neurovascular assessment and notify the provider

Explanation: Severe pain that is disproportionate to the injury, particularly when it does not improve with prescribed analgesia, should raise concern for compartment syndrome. The accompanying coolness and numbness suggest impaired circulation and nerve function. The nurse should immediately assess distal pulses, capillary refill, skin temperature and color, sensation, and movement, comparing findings with the unaffected limb. The provider must be notified promptly because increasing compartment pressure can cause permanent muscle and nerve damage. Elevating the limb excessively may further reduce arterial blood flow, so routine high elevation is inappropriate when significant vascular compromise is suspected.

Question 2. A patient has returned to the orthopedic unit after a total hip arthroplasty. Which patient position should the nurse question?

A. Supine with an abduction pillow between the legs

B. Sitting in a chair with the hips slightly higher than the knees

C. Side-lying with the operative leg supported according to the prescribed precautions

D. Sitting on a low couch with the hips flexed sharply forward

Correct Answer. D. Sitting on a low couch with the hips flexed sharply forward

Explanation: Excessive hip flexion can increase the risk of dislocation after total hip arthroplasty, depending on the surgical approach and precautions prescribed for the patient. A low couch encourages the patient to bend the hip beyond the recommended angle and should therefore be avoided during the early recovery period. The patient should use appropriately elevated seating and follow the specific positioning instructions provided by the orthopedic team. An abduction pillow may help maintain appropriate alignment when ordered. Because precautions can vary according to the surgical approach, the nurse should reinforce the patient’s individualized postoperative instructions rather than applying identical restrictions to every patient.

Question 3. A patient with skeletal traction for a femoral fracture asks why the nurse checks the pin sites regularly. Which response is most appropriate?

A. “The checks determine whether the bone has completely healed.”

B. “The pin sites can provide an entry point for infection.”

C. “The pins need to be loosened when swelling decreases.”

D. “The checks prevent the traction weight from becoming too heavy.”

Correct Answer. B. “The pin sites can provide an entry point for infection.”

Explanation: Skeletal traction involves inserting pins or wires through bone, which creates a potential pathway for microorganisms to enter deeper tissues. Regular pin-site assessment allows the nurse to identify early evidence of infection, including increasing redness, warmth, swelling, tenderness, drainage, or other changes from the patient’s baseline. Infection involving a skeletal pin can progress beyond the superficial tissues and potentially involve the bone. The traction weights should remain properly positioned and should not be adjusted simply because swelling changes. Monitoring the pin sites is therefore an important part of maintaining patient safety while skeletal traction is being used.

Question 4. A patient with a newly applied forearm cast tells the nurse that the fingers feel increasingly tight and difficult to move. Which additional finding requires the most immediate attention?

A. Mild itching beneath the cast

B. Slight swelling around the fingers

C. Increasing pain with passive finger movement

D. Warm skin surrounding the cast

Correct Answer. C. Increasing pain with passive finger movement

Explanation: Increasing pain with passive movement of the fingers is a concerning finding because it may indicate rising pressure within a closed muscle compartment. Compartment syndrome can develop after fractures, significant swelling, or restrictive casts and can compromise circulation and nerve function. It is particularly concerning when pain is severe or disproportionate to the injury and is accompanied by sensory or motor changes. Mild itching and some swelling can occur after cast application and are not, by themselves, diagnostic of a serious complication. The nurse should promptly perform a focused neurovascular assessment and communicate concerning findings to the appropriate healthcare provider.

Question 5. A patient recovering from spinal surgery suddenly develops weakness in both legs and reports new loss of bladder control. What is the nurse’s priority action?

A. Reassure the patient that temporary weakness is expected

B. Assist the patient to ambulate to assess gait

C. Document the findings and reassess at the end of the shift

D. Notify the surgeon or appropriate provider immediately

Correct Answer. D. Notify the surgeon or appropriate provider immediately

Explanation: New bilateral leg weakness accompanied by loss of bladder control is not a finding that should simply be observed after spinal surgery. Together, these changes may indicate significant neurologic compromise requiring urgent evaluation. The nurse should promptly assess the patient’s neurologic status while immediately communicating the change to the surgeon or appropriate provider according to facility protocol. Attempting to ambulate the patient could increase the risk of injury and does not address the underlying concern. Delaying notification could allow potentially reversible neurologic impairment to progress. The sudden change from the patient’s previous neurological baseline makes this an urgent clinical finding.

Question 6. A patient with a pelvic fracture is receiving opioid medication for severe pain. The nurse finds the patient difficult to awaken, with a respiratory rate of 7 breaths/minute. What is the priority nursing action?

A. Administer the next scheduled dose later

B. Encourage the patient to drink fluids

C. Support airway and breathing and follow the protocol for suspected opioid-induced respiratory depression

D. Place the patient in a comfortable side-lying position and allow the patient to sleep

Correct Answer. C. Support airway and breathing and follow the protocol for suspected opioid-induced respiratory depression

Explanation: A respiratory rate of 7 breaths per minute combined with significant difficulty awakening the patient is consistent with potentially life-threatening opioid-induced respiratory depression. Airway and breathing take immediate priority. The nurse should stimulate and assess the patient, provide appropriate respiratory support, and activate the facility’s emergency response or follow the applicable protocol. An opioid antagonist such as naloxone may be administered when indicated by the patient’s condition and institutional protocol. Simply withholding the next dose does not treat the current respiratory compromise. Continued observation without intervention could allow hypoxemia and respiratory arrest to develop.

Question 7. A patient with a lower-extremity fracture is being assessed several hours after the injury. Which finding most strongly suggests impaired neurovascular status?

A. Mild bruising near the fracture

B. Capillary refill of 4 seconds in the affected toes

C. Moderate tenderness at the injury site

D. Swelling that has remained unchanged

Correct Answer. B. Capillary refill of 4 seconds in the affected toes

Explanation: Capillary refill that is significantly delayed compared with the unaffected extremity can indicate reduced peripheral perfusion and warrants further neurovascular assessment. After a fracture, swelling, bleeding, or external pressure from immobilization can compromise blood flow to distal tissues. The nurse should assess pulses, skin color and temperature, sensation, movement, and capillary refill while comparing both extremities. Bruising, tenderness, and some swelling may be expected around a fracture and are less specific for vascular compromise when they remain stable. A worsening neurovascular assessment should be reported promptly because prolonged inadequate perfusion can result in tissue injury.

Question 8. A patient with a new lower-extremity amputation says, “I can still feel intense pain in the foot that is no longer there.” How should the nurse interpret this report?

A. It indicates that the patient is confused

B. It confirms that the surgical procedure was unsuccessful

C. It may represent phantom limb pain

D. It means the residual limb is infected

Correct Answer. C. It may represent phantom limb pain

Explanation: Phantom limb pain is a recognized phenomenon in which a person experiences pain or other sensations as though they are coming from the amputated portion of an extremity. The experience is real to the patient and should not be dismissed as confusion or imagined discomfort. Phantom sensations may occur after amputation and can vary considerably in character and intensity. The nurse should assess the location, quality, severity, timing, and triggers of the pain while also examining the residual limb for other causes of discomfort. Appropriate pain management and rehabilitation strategies can then be incorporated into the patient’s individualized care plan.

Question 9. A patient recovering from total knee arthroplasty is preparing for discharge. Which instruction is most important for reducing the risk of injury during early recovery?

A. Remain in bed until the follow-up appointment

B. Use the prescribed assistive device and follow the weight-bearing instructions

C. Avoid all movement of the operative knee

D. Stop prescribed exercises once the incision appears healed

Correct Answer. B. Use the prescribed assistive device and follow the weight-bearing instructions

Explanation: Safe mobility is an important component of recovery after total knee arthroplasty. The patient should use the prescribed walker, crutches, or other assistive device correctly and follow the healthcare team’s specific weight-bearing instructions. These measures help reduce falls and protect the healing joint while mobility and strength gradually improve. Complete bed rest can increase the risk of complications and delay functional recovery, while avoiding all knee movement is generally inconsistent with prescribed rehabilitation. Exercises should continue according to the rehabilitation plan rather than being stopped when the incision appears healed because functional recovery extends beyond wound healing.

Question 10. A patient with a long-bone fracture develops sudden shortness of breath, confusion, and a fine petechial rash on the upper chest. The nurse should suspect which complication?

A. Fat embolism syndrome

B. Chronic osteomyelitis

C. Degenerative joint disease

D. Venous stasis dermatitis

Correct Answer. A. Fat embolism syndrome

Explanation: Fat embolism syndrome is a potentially serious complication associated particularly with major long-bone or pelvic fractures. The classic clinical pattern includes respiratory deterioration, neurological changes such as confusion or altered consciousness, and a petechial rash that may appear on the chest, neck, axillae, or conjunctivae. Symptoms often develop after the initial injury rather than immediately at the time of fracture. The nurse should recognize this combination as an urgent change in condition, provide appropriate supportive care, monitor oxygenation and respiratory status, and promptly notify the healthcare team. Early recognition is important because severe hypoxemia and neurological deterioration can occur.
