CSFA Surgical First Assistant Exam Questions & Answers 2026 (1–10)

✓ Correct answer: D. Regularly calibrating the surgical camera lens system

Answer: Regularly calibrating the surgical camera lens system Regular calibration ensures that all components of the surgical camera lens system are correctly aligned and functioning optimally. This practice maintains the precision and accuracy critical for visual clarity during surgical procedures. Adjusting settings per surgery type and cleaning lenses are important but do not replace the need for regular calibration. Storage methods do not impact alignment directly.

✓ Correct answer: D. Alert the surgeon and assist in increasing the suction to manage the blood.

Answer: Alert the surgeon and assist in increasing the suction to manage the blood. Changing tissue coloration can indicate internal bleeding. The immediate action should be to communicate with the surgeon about the observed change and manage the bleeding with increased suction to clear the field and allow the surgeon to address the bleeding source. Continuing without adjustments can delay identifying and managing the bleeding source. Increasing insufflation pressure does not address the presence of blood and can complicate the procedure. Requesting additional $$CO_{2}$$ without addressing the bleeding can worsen patient conditions without solving the problem.

✓ Correct answer: B. Notify the surgeon and the operating team of the bleeding

Answer: Notify the surgeon and the operating team of the bleeding. In a crisis such as unexpected heavy bleeding, ensuring that the surgeon and the operating team are immediately aware is crucial. This step allows the team to collaborate effectively on the necessary interventions to manage the bleeding, whether that involves stopping the procedure or shifting to alternate methods. While taking independent actions to control the bleeding might seem appropriate, it should not precede the critical communication with the team. Preparing equipment and evaluating options are practical next steps but they should come after the essential notification.

✓ Correct answer: A. Clean the camera lens with a non-abrasive solution

Cleaning the camera lens with a non-abrasive solution is critical to ensure the visual clarity provided by the laparoscopic camera system during a procedure. This step removes any contamination that could obstruct the surgeon's view, leading to clearer and more precise image transmission. While checking secure cable connections, verifying the bulb in the light source, and testing the control box are all important steps, they do not directly affect the immediate visual clarity. Cable connections and control box functionality are more related to ensuring overall system operation. The light source's operational status ensures illumination rather than camera clarity.

✓ Correct answer: B. Manually monitor the patient's vital signs using available clinical skills and tools

The immediate priority when patient monitoring equipment fails is to ensure that vital signs are being continuously observed and recorded. Manually monitoring vital signs should be the first action taken to avoid any lapse in patient observation, thus ensuring patient safety. Waiting for a technician could cause dangerous delays, and canceling the surgery without addressing the immediate need for monitoring could compromise patient safety. Attempting repairs should not be the first priority unless the individual is specifically trained to do so.

✓ Correct answer: C. Cortisol

Answer: Cortisol In Cushing's syndrome, there is an overproduction of cortisol, a hormone produced by the adrenal cortex. This elevation leads to symptoms like increased blood glucose, hypertension, and abnormal fat distribution. Elevated cortisol is a hallmark of Cushing's syndrome. Triiodothyronine and parathyroid hormone, though important, are not related to the symptoms or the hormonal imbalance seen in Cushing's. Insulin is involved in blood glucose regulation but does not elevate in Cushing's syndrome as part of the primary condition.

✓ Correct answer: A. Diaphragmatic hernia

A diaphragmatic hernia is characterized by an abnormal opening in the diaphragm, allowing abdominal organs to move into the chest cavity. This can cause respiratory distress and interfere with lung and heart functions. A hiatal hernia involves only the stomach moving into the chest through the diaphragm and typically causes acid reflux, not respiratory distress. An inguinal hernia occurs in the groin area, where the intestine protrudes through the abdominal muscles, and does not cause respiratory issues. An umbilical hernia presents as a bulge near the belly button due to weakness in the abdominal wall and does not involve the diaphragm or the chest cavity.

✓ Correct answer: D. Long thoracic nerve

The long thoracic nerve runs along the chest wall and is responsible for innervating the serratus anterior muscle. During a radical mastectomy, there's a risk of damaging this nerve, which can lead to winged scapula—a condition that impairs shoulder movement and function. The phrenic nerve is involved in diaphragmatic movement and is not typically at risk during a mastectomy. The brachial artery is a major blood vessel of the arm and not closely associated with the area of a radical mastectomy. The thyroid gland is located in the neck and is not relevant to mastectomy procedures.

✓ Correct answer: B. 3.0 mL

To determine the correct volume of solution to prepare, you divide the required dose by the concentration: $$\frac{75 \text{ mg}}{25 \text{ mg/mL}} = 3.0 \text{ mL}$$. This ensures the assistant prepares the correct volume for the procedure. The distractors represent common errors such as miscalculating the division or misunderstanding the dose-concentration relationship.

✓ Correct answer: A. Wound edges

The wound edges are often subjected to significant tension, especially if the sutures are tight. This can lead to complications such as ischemia, where restricted blood flow can slow healing or cause tissue necrosis, and dehiscence, which is the reopening of the wound. The suture knot and middle of the suture loop generally do not experience as much direct tension in terms of compromising the tissue, while the suture tail is not involved in the closure tension.
