WGU Pathophysiology Final Exam
1. A male patient is receiving testosterone therapy for hypogonadism. What adverse effect should the nurse monitor during this therapy?
- A. Increased risk of cardiovascular events
- B. Increased risk of liver dysfunction
- C. Increased risk of prostate cancer
- D. Increased risk of bone fractures
Correct answer: A
Rationale: The correct answer is A: Increased risk of cardiovascular events. Testosterone therapy can lead to an increased risk of cardiovascular events like heart attacks and strokes, especially in older patients. Choice B, increased risk of liver dysfunction, is not a common adverse effect of testosterone therapy. Choice C, increased risk of prostate cancer, is a concern when using testosterone therapy in patients with existing prostate cancer, but not a general adverse effect. Choice D, increased risk of bone fractures, is not typically associated with testosterone therapy.
2. Which physiologic response is most likely to accompany activation of the parasympathetic nervous system?
- A. Increased heart rate
- B. Increased gastric motility
- C. Pupil dilation
- D. Sweating
Correct answer: B
Rationale: The correct answer is B: Increased gastric motility. The parasympathetic nervous system is known to promote rest and digest functions, which includes increasing gastric motility to aid in digestion. Choices A, C, and D are incorrect as they are more characteristic of the sympathetic nervous system. The sympathetic nervous system is responsible for the fight or flight response, leading to increased heart rate (Choice A), pupil dilation (Choice C), and sweating (Choice D) among other responses.
3. When arterial blood pressure declines, the kidneys secrete a hormone to increase blood pressure and peripheral resistance. What is this hormone called?
- A. Renin
- B. Antidiuretic hormone
- C. Atrial natriuretic
- D. Insulin
Correct answer: A
Rationale: Renin is the correct answer. When arterial blood pressure decreases, the kidneys release renin, which triggers a series of reactions ultimately leading to an increase in blood pressure and peripheral resistance. Antidiuretic hormone (choice B) is involved in water retention, atrial natriuretic hormone (choice C) promotes sodium excretion and lowers blood pressure, and insulin (choice D) regulates glucose metabolism, not blood pressure.
4. After teaching the students about B cells, which statement indicates teaching was successful? B cells are originally derived from cells of the:
- A. Bone marrow
- B. Lymph nodes
- C. Gut-associated lymphoid tissue
- D. Thymus
Correct answer: A
Rationale: The correct answer is A: Bone marrow. B cells are originally derived from cells of the bone marrow. Bone marrow is the primary site where B cells develop and mature. Lymph nodes (choice B), gut-associated lymphoid tissue (choice C), and the thymus (choice D) are involved in the immune response but are not the primary site of origin for B cells.
5. Which manifestation of stress reflects the non-specific fight or flight response?
- A. Decreased pupillary light response
- B. Increased GI motility
- C. Decreased short-term memory
- D. Increased cardiopulmonary rates
Correct answer: D
Rationale: The correct answer is D, 'Increased cardiopulmonary rates.' The fight or flight response, activated by stress, is a non-specific physiological reaction that prepares the body to deal with perceived threats. In this response, the heart rate and breathing rate increase to supply more oxygen to muscles and vital organs, enabling a rapid response in dangerous situations. Choices A, B, and C are incorrect because decreased pupillary light response, increased GI motility, and decreased short-term memory are not typical manifestations of the fight or flight response.
