Free Certified Surgical Technologist MCQ Questions and Answers

Question 1

What number of white blood cells in an adult is considered normal?

Accepted Answer

5000 to 9000

Answer

A normal white blood cell (WBC) count in an adult typically ranges from 5,000 to 9,000 cells per microliter of blood. White blood cells, or leukocytes, are crucial components of the immune system, fighting off infections and other diseases. Counts outside this range can indicate underlying medical conditions, such as infection (leukocytosis) or immunosuppression (leukopenia).

Question 2

What bodily part undergoes preparation for an ORIF of the humerus?

Accepted Answer

Arm, fingers to shoulder

Answer

For an Open Reduction Internal Fixation (ORIF) of the humerus, the surgical preparation area must encompass the entire arm, extending from the fingertips up to the shoulder. This wide prep area ensures that the surgical team has sterile access to the entire bone and surrounding tissues, accommodating potential extensions of the incision or manipulation of the limb during the procedure. It also accounts for any necessary draping and movement of the arm.

Question 3

Which of the following equipment should be included in a TURP setup?

Accepted Answer

Resectoscope

Answer

A Transurethral Resection of the Prostate (TURP) is a surgical procedure used to treat benign prostatic hyperplasia (BPH). The primary instrument used for a TURP is a resectoscope, which is a specialized endoscope equipped with a wire loop that uses high-frequency electrical current to cut and coagulate prostatic tissue. This allows for the removal of obstructing prostate tissue through the urethra without an external incision.

Question 4

Which medications can elevate the patient's blood pressure in an emergency?

Accepted Answer

Epinephrine (Adrenalin)

Answer

Epinephrine, also known as Adrenalin, is a potent vasoconstrictor and cardiac stimulant commonly used in emergency situations to elevate blood pressure. It acts on alpha and beta adrenergic receptors, causing peripheral vasoconstriction and increasing heart rate and contractility. This makes it a critical medication for treating conditions like anaphylactic shock or severe hypotension.

Question 5

The parathyroid hormone controls

Accepted Answer

Calcium

Answer

The parathyroid hormone (PTH), secreted by the parathyroid glands, is the primary regulator of calcium and phosphate levels in the blood. PTH increases blood calcium levels by stimulating calcium release from bones, increasing calcium reabsorption in the kidneys, and promoting vitamin D activation, which enhances intestinal calcium absorption. Maintaining proper calcium balance is vital for bone health, nerve function, and muscle contraction.
