Section 1: Pre/Postoperative Patient Assessment and Diagnosis (Questions 1-25)
1. A nurse is encouraging a post-operative patient to cough and take deep
breaths. This nursing action is due to the understanding by the nurse that
retaining pulmonary secretions can lead to:
a) Atelectasis
b) Pneumonia
c) Pulmonary edema
d) Pneumothorax
Rationale: Retained pulmonary secretions provide a medium for bacterial
growth, leading to pneumonia. Deep breathing and coughing help mobilize
secretions, preventing this common postoperative complication.
2. A patient with severe burns is scheduled for surgery for an allograft of the
right leg. What must be considered as the post-operative plan of care for this
patient?
a) Immediate weight-bearing on the right leg
b) Frequent blood pressure checks on the right leg
c) Immobilize and elevate the right leg
d) Application of dry, sterile gauze only
Rationale: Post-operative care for an allograft (skin graft) requires immobilization
and elevation to promote graft adherence and prevent shearing forces that could
disrupt the graft and compromise healing .
,3. When caring for a patient posted for surgery, the nurse finds that the patient
is not able to sign the consent form due to narcotic analgesic administration.
Who should sign the consent instead of the patient?
a) The surgeon
b) The nurse manager
c) One family member can sign with two witnesses signatures
d) No surgery can be performed
Rationale: If a patient is under the influence of narcotics and cannot give
informed consent, a legally authorized representative (typically a family member)
must sign. Two witnesses are required to validate the process.
4. An 88-year-old woman is posted for surgery. Which of the following consent
processes needs to be followed by a nurse in this case?
a) Rush the consent process due to her age
b) Have the surgeon sign on her behalf
c) Provide adequate time for the patient to process the information and sign
d) Assume she cannot consent due to age
Rationale: Age alone does not determine competency. Elderly patients may
require more time to process information. The nurse must ensure the patient has
adequate time to understand the procedure and sign voluntarily.
5. A nurse is caring for a patient with radical neck dissection. The endotracheal
tube was removed a few minutes ago. When observing which of the following
must the nurse call the physician?
a) Snoring
b) Coughing
c) Stridor
d) Hoarseness
Rationale: Stridor is a high-pitched, harsh sound indicating upper airway
,obstruction. After a radical neck dissection, edema can compromise the airway,
and stridor is a medical emergency requiring immediate intervention.
6. A nurse is caring for a patient who is posted for surgery. Which of the
following would make the nurse suspect that the patient is in cardiogenic
shock?
a) Bounding pulses
b) Muffled heart sounds
c) Increased urine output
d) Warm, dry skin
Rationale: Muffled heart sounds are a classic sign of cardiac tamponade, which
can cause cardiogenic shock. This occurs when fluid accumulates in the
pericardial sac, compressing the heart and reducing cardiac output.
7. A patient is scheduled for a total knee arthroplasty. Which pre-operative
assessment finding is most critical to report to the surgical team?
a) History of seasonal allergies
b) Presence of a skin infection or lesion on the operative knee
c) Previous knee surgery 10 years ago
d) Patient anxiety about the procedure
Rationale: The presence of any skin infection near the surgical site is a critical
finding as it significantly increases the risk of post-operative surgical site infection
(SSI) and may necessitate delaying the procedure .
8. When assessing a patient with a history of obstructive sleep apnea (OSA)
pre-operatively, the perioperative nurse should anticipate:
a) Shorter recovery time
b) Increased risk for airway complications and need for specialized equipment
c) No change in anesthetic plan
d) Decreased need for post-operative monitoring
, Rationale: Patients with OSA are at higher risk for airway obstruction,
desaturation, and difficult intubation. The care plan must include specialized
airway equipment, careful extubation, and close monitoring.
9. A patient reports using herbal supplements, including ginkgo biloba, prior to
surgery. The nurse is aware that this supplement increases the risk of:
a) Hypertension
b) Hyperglycemia
c) Bleeding
d) Serotonin syndrome
Rationale: Ginkgo biloba has anticoagulant properties due to its inhibition of
platelet-activating factor. It can increase bleeding risk during and after surgery
and is typically discontinued 2-3 weeks pre-operatively.
10. Which laboratory value would be most concerning for a patient undergoing
surgery under general anesthesia?
a) Hemoglobin 12 g/dL
b) Potassium 2.8 mEq/L
c) Sodium 138 mEq/L
d) Glucose 110 mg/dL
Rationale: Hypokalemia (low potassium) increases the risk of cardiac
arrhythmias, especially when combined with anesthesia and surgical stress. This
level requires correction before proceeding with surgery.
11. The pre-operative nurse is educating a patient about deep vein thrombosis
(DVT) prophylaxis. Which statement indicates the patient understands the
teaching?
a) "I should keep my legs crossed while resting in bed."
b) "I will use my sequential compression devices as instructed."
c) "I don't need to move my legs until after surgery."
