Which techniques would the registered nurse identify as regional anesthesia to a patient undergoing surgery? (Select all that apply.)
Oral route Anesthetic Block
Inhalation Anesthetic Block
Spinal Anesthetic Block
Epidural Anesthetic Block
Nerve Anesthetic Block
Correct Answer : C,D,E
Choice A rationale:
Oral route anesthetic blocks are not considered regional anesthesia. They are a form of systemic anesthesia, meaning they affect the entire body.
Oral anesthetics are absorbed through the gastrointestinal tract and distributed throughout the bloodstream to reach their target sites in the central nervous system.
They produce a general depressant effect on the brain and spinal cord, leading to sedation, unconsciousness, and analgesia. Examples of oral anesthetics include benzodiazepines, barbiturates, and propofol.
Choice B rationale:
Inhalation anesthetic blocks are also a form of systemic anesthesia.
They are administered through inhalation of vaporized gases or volatile liquids.
These anesthetics rapidly cross the alveolar-capillary membrane in the lungs and enter the bloodstream, where they are transported to the brain and other tissues.
They produce a dose-dependent depression of the central nervous system, resulting in loss of consciousness, analgesia, and muscle relaxation.
Examples of inhalation anesthetics include nitrous oxide, sevoflurane, and isoflurane.
Choice C rationale:
Spinal anesthetic blocks are a type of regional anesthesia that involves injecting a local anesthetic directly into the subarachnoid space of the spinal cord.
This blocks nerve transmission in the spinal cord, resulting in loss of sensation and motor function in the lower half of the body.
Spinal anesthesia is commonly used for surgeries below the waist, such as cesarean deliveries, hip replacements, and knee surgeries.
Choice D rationale:
Epidural anesthetic blocks are another type of regional anesthesia that involves injecting a local anesthetic into the epidural space, which is the area surrounding the spinal cord.
This blocks nerve transmission in the spinal nerves, resulting in loss of sensation and motor function in a specific region of the body.
Epidural anesthesia is commonly used for labor and delivery, as well as for surgeries on the abdomen, pelvis, and lower extremities.
Choice E rationale:
Nerve anesthetic blocks (also known as peripheral nerve blocks) involve injecting a local anesthetic around a specific nerve or group of nerves.
This blocks nerve transmission in the targeted area, resulting in loss of sensation and motor function in a specific part of the body.
Nerve blocks can be used for a variety of surgical procedures, as well as for pain management.

Correct Answer is D
Explanation
Choice A rationale:
Secondary prevention focuses on early detection and treatment of diseases or conditions to prevent complications or progression. It does not involve education about health promotion activities like exercise.
Examples of secondary prevention include:
Screening for cancer (e.g., mammograms, colonoscopies)
Regular blood pressure checks
Immunizations
Taking medications to manage chronic conditions (e.g., diabetes, hypertension)
Choice B rationale:
Restorative care aims to restore function and quality of life after an illness or injury. It does not encompass health education strategies like the nurse's action in this scenario.
Examples of restorative care include:
Physical therapy
Occupational therapy
Speech therapy
Rehabilitation programs
Choice C rationale:
Tertiary prevention focuses on managing existing diseases or conditions to prevent further complications and improve quality of life. It's not applicable to this scenario as no disease or condition is being managed.
Examples of tertiary prevention include:
Cardiac rehabilitation after a heart attack
Diabetes management education
Pulmonary rehabilitation for chronic lung disease
Choice D rationale:
Primary prevention targets preventing diseases or conditions from occurring in the first place. It often involves education and lifestyle changes to promote health and wellness.
The nurse's action of educating adolescents about physical exercise aligns with primary prevention. Exercise has proven benefits in:
Reducing the risk of chronic diseases like obesity, heart disease, stroke, type 2 diabetes, and some types of cancer Improving mental health and well-being
Promoting bone and muscle health
Enhancing sleep quality
Reducing stress levels
Therefore, the nurse's activity of educating adolescents about exercise represents primary prevention.
Correct Answer is C
Explanation
Choice A rationale:
While it's true that gastrointestinal peristalsis may be slowed after surgery, this is not the primary reason for administering a cleansing enema before colon surgery.
The main goal of the enema is to evacuate stool from the colon, ensuring a clear and unobstructed surgical field. This helps to:
Reduce the risk of infection
Facilitate better visualization of the colon during surgery
Minimize the potential for complications
Choice B rationale:
Cleansing enemas are not administered solely based on patient request.
They are prescribed for specific medical reasons, such as preparing for colon surgery or certain diagnostic procedures. Patient preference may be considered, but it's not the determining factor.
Choice C rationale:
While decreased gas and discomfort post-operatively can be a potential benefit of a cleansing enema, it's not the primary reason for its use before colon surgery.
The primary goal, as mentioned earlier, is to clear the colon for a safe and effective surgical procedure. However, reduced gas and discomfort can contribute to a smoother post-operative recovery.
Choice D rationale:
Multiple cleansing enemas are not routinely given to all surgical patients.
The decision to administer an enema is based on the specific type of surgery, the patient's condition, and other factors. In some cases, a single enema may be sufficient, while others may require more than one.
