What is the most effective method for preventing the spread of disease?
- A. Hand hygiene
- B. Vaccination
- C. Quarantine
- D. Use of personal protective equipment
Correct Answer: A
Rationale: The correct answer is A: Hand hygiene. Proper hand hygiene, including washing hands with soap and water or using hand sanitizer, is the most effective method for preventing the spread of disease. This is because hands can easily pick up and transfer germs from surfaces to our bodies. Regular handwashing can remove these germs and reduce the risk of infection.
Summary of other choices:
B: Vaccination is important in preventing certain diseases but may not be as effective in controlling the immediate spread of a disease outbreak.
C: Quarantine can help contain the spread of disease in specific situations but may not be as universally applicable as hand hygiene.
D: Use of personal protective equipment is crucial in certain settings, but it is not as practical or accessible for the general population compared to practicing good hand hygiene.

Match the following terms in column A with the correct definition in Column B:
- A. I. Topical anesthesia
C. The agent is applied directly to the skin and mucous membranes of the skin.
II. Epidural anesthesia
D. Injecting the anesthesia in the epidural mater of the spinal cord. - B. II. Epidural anesthesia
B. Anesthesia is introduced in the subarachnoid space at the lumbar area L4 and L5.
I. Topical anesthesia
C. The agent is applied directly to the skin and mucous membranes of the skin. - C. I. Topical anesthesia
C. The agent is applied directly to the skin and mucous membranes of the skin.
II. Epidural anesthesia
D. Injecting the anesthesia in the epidural mater of the spinal cord. - D. I. Topical anesthesia
C. The agent is applied directly to the skin and mucous membranes of the skin.
II. Epidural anesthesia
B. Anesthesia is introduced in the subarachnoid space at the lumbar area L4 and L5.
Correct Answer: A
Rationale: The correct answer is A because it correctly matches the terms with their definitions. Topical anesthesia is indeed applied directly to the skin and mucous membranes, matching with statement C. Epidural anesthesia involves injecting the anesthesia into the epidural space of the spinal cord, aligning with statement D. The other choices incorrectly match the terms with definitions that do not correspond to the actual procedures. Choice B incorrectly states that epidural anesthesia is introduced in the subarachnoid space at the lumbar area L4 and L5, which is not accurate. Choice C incorrectly states that topical anesthesia is applied directly to the skin and mucous membranes, which is inaccurate. Choice D incorrectly states that topical anesthesia is applied directly to the skin and that epidural anesthesia is introduced in the subarachnoid space, both of which are incorrect.
Which fluid is used in the management of gastrointestinal tract (GIT) loss and burns?
- A. Ringer's lactate
- B. Normal saline
- C. Dextrose
- D. Blood
Correct Answer: A
Rationale: The correct answer is A: Ringer's lactate. Ringer's lactate is used in managing GIT loss and burns due to its balanced electrolyte composition, which closely resembles the electrolyte content of plasma. It helps replace lost fluids and maintain electrolyte balance. Normal saline (B) lacks bicarbonate and may lead to metabolic acidosis. Dextrose (C) provides energy but does not address fluid and electrolyte losses. Blood (D) is not typically used for fluid resuscitation in these cases unless there is severe hemorrhage.
Which is an example of tertiary prevention?
- A. Providing rehabilitation services
- B. Diagnosing and treating disease
- C. Health education to prevent complications
- D. Screening for complications
Correct Answer: A
Rationale: The correct answer is A because tertiary prevention focuses on managing and rehabilitating individuals who already have a disease or condition to prevent further complications and improve quality of life. Providing rehabilitation services falls under tertiary prevention as it aims to restore function and reduce disability post-diagnosis.
B: Diagnosing and treating disease is considered secondary prevention, which aims to detect and treat diseases early to prevent progression.
C: Health education to prevent complications is an example of primary prevention, which aims to prevent the development of diseases or conditions.
D: Screening for complications is part of secondary prevention, as it involves early detection and treatment to prevent complications.
Which sign or reflex is used to diagnose meningitis?
- A. Homan's sign
- B. Brudzinski
- C. Startle
- D. Anterior drawer
Correct Answer: B
Rationale: The correct answer is B: Brudzinski sign. This sign is used to diagnose meningitis because it involves the involuntary flexion of the hips and knees when the neck is flexed. This reflex is indicative of meningeal irritation and is a classic sign of meningitis.
A: Homan's sign is used to assess for deep vein thrombosis, not meningitis.
C: Startle reflex is a normal response to a sudden unexpected stimulus, not specific to meningitis.
D: Anterior drawer test is used to assess for ligamentous instability in the knee, not related to meningitis.
Which is a key aspect of the Health Belief Model?
- A. Perceived susceptibility
- B. Perceived severity
- C. Perceived barriers
- D. Perceived benefits
Correct Answer: A
Rationale: The correct answer is A: Perceived susceptibility. This is a key aspect of the Health Belief Model because it refers to an individual's belief about their risk of getting a particular health condition. It is crucial in determining whether a person will take preventive actions. Perceived severity (B) and perceived benefits (D) are also important components of the model, but perceived susceptibility is considered the starting point for behavior change. Perceived barriers (C) are obstacles that may prevent an individual from taking action, but they are not the main focus in the Health Belief Model.
