Pathophysiology Final Exam
1. A nurse is teaching a patient about the use of testosterone gel for the treatment of hypogonadism. What important instruction should the nurse provide?
- A. Apply the gel after showering, and allow it to dry completely before dressing.
- B. Apply the gel to the genitals for maximum absorption.
- C. Apply the gel before bedtime to enhance absorption during sleep.
- D. Apply the gel to the face and neck for improved results.
Correct answer: A
Rationale: The correct instruction is to apply testosterone gel after showering and allow it to dry completely before dressing. This helps prevent the transfer of the gel to others and ensures proper absorption. Choice B is incorrect because the gel should not be applied to the genitals. Choice C is incorrect as there is no specific benefit to applying the gel before bedtime. Choice D is incorrect as the gel should not be applied to the face and neck for the treatment of hypogonadism.
2. During a well-child checkup, a mother tells Nurse Rio about a recent situation in which her child needed to be disciplined by her husband. The child was slapped in the face for not getting her husband breakfast on Saturday, despite being told on Thursday never to prepare food for him. Nurse Rio analyzes the family system and concludes it is dysfunctional. All of the following factors contribute to this dysfunction except:
- A. Conflictual relationships between parents.
- B. Inconsistent communication patterns.
- C. Rigid, authoritarian roles.
- D. Use of violence to establish control.
Correct answer: C
Rationale: In a dysfunctional family system, conflictual relationships, inconsistent communication patterns, and the use of violence to establish control are factors contributing to dysfunction. However, rigid, authoritarian roles, though also dysfunctional, are not directly linked to the use of violence for control.
3. Following a spinal cord injury suffered in a motor vehicle accident, a 22-year-old male has lost fine motor function of his finger and thumb, but is still able to perform gross motor movements of his hand and arm. Which component of his 'white matter' has most likely been damaged?
- A. The inner layer (archilayer)
- B. The middle layer (paleolayer)
- C. The outer layer (neolayer)
- D. The reticular formation
Correct answer: C
Rationale: The correct answer is C: The outer layer (neolayer). The white matter of the spinal cord consists of three layers: the outer layer (neolayer), the middle layer (paleolayer), and the inner layer (archilayer). Damage to the outer layer (neolayer) is likely to affect fine motor skills, explaining the loss of fine motor function in the finger and thumb while gross motor movements remain intact. Choices A, B, and D are incorrect as they do not correspond to the specific layer of the white matter that is typically associated with fine motor control.
4. Which of the following is a cause of hypothyroidism?
- A. Overproduction of cortisol
- B. Autoimmune destruction of the thyroid gland
- C. Overactivity of the thyroid gland
- D. Insufficient iodine intake
Correct answer: B
Rationale: The correct answer is B: Autoimmune destruction of the thyroid gland. In hypothyroidism, the thyroid gland does not produce enough hormones to meet the body's needs. This can be due to autoimmune destruction of the thyroid gland, where the body's immune system mistakenly attacks the thyroid tissue. Choices A, C, and D are incorrect. Overproduction of cortisol is associated with conditions like Cushing's syndrome, overactivity of the thyroid gland is a characteristic of hyperthyroidism, and insufficient iodine intake can lead to goiter but not necessarily hypothyroidism.
5. Which of the following hormones do the kidneys secrete to increase red blood cell production?
- A. Erythropoietin
- B. Insulin and glycogen
- C. Testosterone
- D. Thyroid stimulating hormone
Correct answer: A
Rationale: The correct answer is A: Erythropoietin. The kidneys produce erythropoietin to stimulate the production of red blood cells. Insulin and glycogen are not hormones secreted by the kidneys; insulin is produced by the pancreas, and glycogen is a stored form of glucose. Testosterone is a hormone primarily produced by the testes in males and to a lesser extent in females. Thyroid stimulating hormone is produced by the pituitary gland to regulate thyroid function, not red blood cell production.
