1. What is the term for the body's ability to defend itself against specific invading agents such as bacteria, toxins, viruses, and foreign bodies?

• A. Hormones
• B. Secretion
• C. Immunity
• D. Glands

Correct answer: C

Rationale: The correct answer is C: Immunity. Immunity refers to the body's ability to protect itself against specific invading agents like bacteria, toxins, viruses, and foreign bodies by recognizing and destroying them. It is a crucial defense mechanism that helps maintain health and prevent infections and diseases. Choices A, B, and D are incorrect because hormones are chemical messengers, secretion is the process of releasing substances, and glands are organs that produce and release substances, none of which specifically relate to the body's defense against invading agents.

2. Which technique in physical examination is used to assess the movement of air through the tracheobronchial tree?

• A. Palpation
• B. Auscultation
• C. Inspection
• D. Percussion

Correct answer: B

Rationale: The correct answer is B: Auscultation. Auscultation is a technique in physical examination used to assess the movement of air through the tracheobronchial tree. During auscultation, healthcare providers listen to lung sounds using a stethoscope to detect abnormalities such as wheezing, crackles, or diminished breath sounds, which can indicate conditions affecting the airways or lungs. Palpation (Choice A) involves feeling the body for abnormalities, Inspection (Choice C) involves visual examination, and Percussion (Choice D) involves tapping on the body to produce sounds that can help in assessing underlying structures, but they are not directly used to assess air movement through the tracheobronchial tree.

3. Which of the following statements about chest X-rays is false?

• A. There are contraindications for this test
• B. Before the procedure, the patient should remove all jewelry, metallic objects, and buttons above the waist
• C. A signed consent is not required
• D. Eating, drinking, and medications are allowed before this test

Correct answer: A

Rationale: The correct answer is A because there are contraindications for chest X-rays, such as pregnancy or concerns about radiation exposure. Patients may need to remove jewelry and metallic objects to prevent interference with the imaging. While a signed consent is typically not required for a routine chest X-ray, there are specific situations where consent may be necessary. It is essential for patients to follow fasting instructions before certain types of chest X-rays to obtain accurate results.

4. In which of the following organs does the exchange of gases take place?

• A. Kidneys
• B. Lungs
• C. Liver
• D. Heart

Correct answer: B

Rationale: The exchange of gases, specifically oxygen and carbon dioxide, occurs in the lungs. In the lungs, oxygen from the air we breathe enters the bloodstream, while carbon dioxide is removed from the bloodstream and exhaled. This process is essential for respiration and supplying the body with oxygen for energy production. The kidneys filter waste from the blood to produce urine and regulate fluid balance (Choice A). The liver is involved in detoxification, protein synthesis, and producing bile (Choice C). The heart is responsible for pumping blood throughout the body to deliver oxygen and nutrients (Choice D).

5. When caring for a toddler with acute lymphocytic leukemia, in which of the following activities should the toddler participate?

• A. Looking at alphabet flashcards.
• B. Playing with a large plastic truck.
• C. Using scissors to cut out paper shapes.
• D. Watching a cartoon in the dayroom.

Correct answer: B

Rationale: Toddlers with acute lymphocytic leukemia may have compromised immune systems and need to avoid activities that increase infection risk. Playing with a large plastic truck is a safe and engaging activity that does not pose a high risk of infection. This choice also promotes physical activity and creativity, which are beneficial for a toddler's development during illness.
