ATI Pathophysiology Exam 2
1. What aspect of this woman's current health status would contraindicate the use of oral contraceptives?
- A. The woman has a diagnosis of type 2 diabetes.
- B. The woman has asthma and uses inhaled corticosteroids and bronchodilators.
- C. The woman has a family history of breast cancer.
- D. The woman takes an antiplatelet medication for coronary artery disease.
Correct answer: A
Rationale: The correct answer is A. Women with type 2 diabetes are at higher risk of developing cardiovascular complications. Oral contraceptives further increase this risk due to their potential effects on blood pressure, lipid metabolism, and clotting factors. Choice B is incorrect as inhaled corticosteroids and bronchodilators do not contraindicate the use of oral contraceptives. Choice C is incorrect as a family history of breast cancer does not directly contraindicate the use of oral contraceptives. Choice D is also incorrect as taking an antiplatelet medication for coronary artery disease does not necessarily contraindicate the use of oral contraceptives.
2. A nursing student having trouble moving her head from side to side is likely experiencing a problem with which type of neurons?
- A. General visceral efferent neurons
- B. Preganglionic neurons
- C. Parasympathetic postganglionic neurons
- D. Pharyngeal efferent neurons
Correct answer: D
Rationale: The correct answer is D: Pharyngeal efferent neurons. Pharyngeal efferent neurons are responsible for controlling head movements, including side-to-side motions. General visceral efferent neurons (Choice A) are involved in innervating smooth muscles and glands in the body's internal organs. Preganglionic neurons (Choice B) are part of the autonomic nervous system and connect the central nervous system to the ganglia. Parasympathetic postganglionic neurons (Choice C) are the second neurons in the parasympathetic nervous system pathway, responsible for innervating target organs. In this case, the issue with moving the head from side to side indicates a problem with the pharyngeal efferent neurons.
3. The college health nurse is providing health education for freshmen. Which of the following pieces of information about immunizations is applicable to individuals of this age group?
- A. The oral polio vaccine should be updated.
- B. The yearly administration of flu vaccine is recommended.
- C. The tetanus toxoid should be within 2 years.
- D. The administration of hepatitis A vaccine is mandatory.
Correct answer: B
Rationale: For freshmen in college, the yearly administration of the flu vaccine is recommended. This is important to protect against seasonal influenza outbreaks that can spread rapidly in close living quarters such as dormitories. Choice A is incorrect as oral polio vaccine is not typically given to individuals of this age group. Choice C is incorrect as tetanus toxoid boosters are usually recommended every 10 years, not within 2 years. Choice D is incorrect as the administration of the hepatitis A vaccine is not mandatory for all individuals in this age group.
4. What is the primary function of the kidneys in acid-base balance?
- A. The kidneys remove hydrogen ions and retain bicarbonate ions.
- B. The kidneys convert ammonia into urea, which is excreted in the urine.
- C. The kidneys produce aldosterone to regulate sodium levels.
- D. The kidneys secrete renin to regulate blood pressure.
Correct answer: A
Rationale: The correct answer is A. The kidneys are crucial in maintaining acid-base balance by removing hydrogen ions to decrease acidity and retaining bicarbonate ions to increase alkalinity. Choice B is incorrect because the conversion of ammonia into urea is related to nitrogen waste excretion, not acid-base balance. Choice C is incorrect as aldosterone regulates sodium levels, not acid-base balance. Choice D is also incorrect as renin is involved in regulating blood pressure, not acid-base balance.
5. 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.
