ATI Pathophysiology Exam 1
1. An infant is being administered an immunization. Which of the following provides an accurate description of an immunization?
- A. It should be administered to a pregnant woman prior to the infant's birth.
- B. It is the administration of an antigen to stimulate an antibody response.
- C. It produces many adverse reactions, particularly autism, in the infant.
- D. It protects the infant from exposure to infectious antibodies.
Correct answer: B
Rationale: The correct answer is B. Immunization involves administering an antigen, such as a weakened or killed microorganism, to stimulate the immune system to produce an antibody response. This process helps the body recognize and remember specific pathogens, providing immunity against future infections. Choice A is incorrect because immunizations are administered to the infant directly, not to the pregnant woman before birth. Choice C is incorrect as there is no scientific evidence linking immunizations to autism. Choice D is incorrect as immunizations protect against infectious agents, not antibodies.
2. A patient is receiving oral nystatin suspension for a fungal infection of the mouth. Which of the following adverse effects is most likely to be experienced with this form of nystatin?
- A. Local irritation
- B. Burning
- C. Nausea
- D. Urinary urgency
Correct answer: A
Rationale: The correct answer is A: Local irritation. When using oral nystatin suspension for a fungal infection of the mouth, local irritation is the most likely adverse effect that a patient may experience. Nystatin is generally well-tolerated, but some patients may develop local irritation, such as mouth or throat irritation. Choices B, C, and D are less likely adverse effects of oral nystatin suspension. Burning, nausea, and urinary urgency are not commonly associated with nystatin use for a fungal infection of the mouth.
3. What type of shock is characterized by a hypersensitivity reaction causing massive vasodilation and capillary leaks, which may occur with drug or latex allergy?
- A. Neurogenic shock
- B. Cardiogenic shock
- C. Hypovolemic shock
- D. Anaphylactic shock
Correct answer: D
Rationale: Anaphylactic shock is a severe allergic reaction that causes massive vasodilation and increased capillary permeability, leading to rapid fluid shifts and circulatory collapse if not treated promptly. Neurogenic, cardiogenic, and hypovolemic shocks have different etiologies.
4. G. Stanley Hall and his student, Arnold Gesell, __________.
- A. discovered that prenatal growth is strikingly similar in many species
- B. launched the normative approach
- C. constructed the first standardized intelligence test
- D. were the forefathers of psychoanalytic theory
Correct answer: B
Rationale: G. Stanley Hall and his student, Arnold Gesell, launched the normative approach. This approach involves studying large numbers of people of different ages and examining the age-related averages of behaviors to establish norms or typical development patterns. These scholars focused on the systematic observation of how and when certain behaviors appear in children. Choices A, C, and D are incorrect because they do not accurately reflect the contributions of G. Stanley Hall and Arnold Gesell in the field of developmental psychology.
5. During the second month of pregnancy, __________.
- A. the umbilical cord first appears as a primitive body stalk
- B. touch sensitivity extends to most of the body
- C. the heart develops separate chambers
- D. the heartbeat can be heard through a stethoscope
Correct answer: C
Rationale: During the second month of pregnancy, the heart of the developing fetus begins to develop separate chambers, forming the structure necessary for a fully functioning heart. This is a significant milestone in the prenatal development process. Choices A, B, and D are incorrect because the appearance of the umbilical cord as a primitive body stalk typically occurs around week 5-6, touch sensitivity extending to most of the body is more characteristic of the end of the second trimester, and the heartbeat is usually detectable through a stethoscope around the 18th to 20th week of pregnancy, not during the second month.
