Question 1

A 58-year-old male patient with well-controlled type 2 diabetes and hypertension is scheduled for multiple extractions under IV sedation. His morning blood glucose reading was 150 mg/dL. Which of the following is the most appropriate action for the dental anesthesia assistant to anticipate?

Accepted Answer

Scheduling the patient for the first appointment of the day.

Answer

Patients with diabetes should be scheduled for morning appointments to minimize the disruption of their meal and medication schedules and to avoid hypoglycemia. Withholding antihypertensives could lead to dangerously high blood pressure during the procedure. Prophylactic antibiotics are not routinely indicated solely based on diabetes unless there is a specific risk of infection. A local anesthetic with a vasoconstrictor is generally safe for patients with well-controlled diabetes and hypertension, and it helps to provide profound anesthesia.

Question 2

According to the ASA Physical Status Classification System, a patient with severe systemic disease that is a constant threat to life, such as unstable angina or end-stage renal disease, would be classified as:

Accepted Answer

ASA IV

Answer

The ASA Physical Status Classification System categorizes patients based on their overall health. An ASA IV classification is assigned to a patient with a severe systemic disease that is a constant threat to life. ASA II is for mild systemic disease, ASA III is for severe systemic disease that limits activity but is not incapacitating, and ASA V is for a moribund patient not expected to survive without the operation.

Question 3

A patient with a history of moderate, persistent asthma is undergoing a procedure with conscious sedation. Which of the following medications should be readily available in the emergency kit for this patient?

Accepted Answer

A short-acting beta-agonist inhaler (e.g., albuterol)

Answer

For a patient with asthma, it is crucial to have a rescue inhaler, such as albuterol, readily available to treat an acute bronchospasm. While epinephrine may be used in severe, life-threatening asthma attacks, the first-line treatment for a typical exacerbation is a short-acting beta-agonist. Atropine is used for bradycardia, and naloxone is an opioid antagonist.

Question 4

During a pre-anesthetic evaluation, a patient reports taking 20 mg of prednisone daily for the past year for an autoimmune condition. This long-term steroid use may cause which of the following conditions, requiring special consideration?

Accepted Answer

Adrenal suppression

Answer

Long-term use of exogenous corticosteroids like prednisone can suppress the body's natural production of cortisol from the adrenal glands. This condition, known as adrenal suppression, can impair the patient's ability to respond to the stress of surgery and anesthesia, potentially leading to an adrenal crisis. Depending on the procedure's stress level, supplemental steroids may be required.

Question 5

A patient with diagnosed liver cirrhosis is scheduled for a procedure under deep sedation. The dental anesthesia assistant should be aware that this condition primarily affects the:

Accepted Answer

Metabolism and clearance of anesthetic drugs.

Answer

The liver is the primary site for the metabolism of many anesthetic and sedative drugs. In a patient with liver cirrhosis, hepatic function is compromised, leading to decreased drug metabolism and clearance. This can result in prolonged and exaggerated drug effects. The anesthesia team must carefully select drugs and adjust dosages for these patients.
