WGU Pathophysiology Final Exam
1. A woman with severe visual and auditory deficits is able to identify individuals by running her fingers lightly over her face. Which source is most likely to provide the input that allows for the woman's unique ability?
- A. Special somatic afferent fibers
- B. General somatic afferents
- C. Special visceral afferent cells
- D. General visceral afferent neurons
Correct answer: C
Rationale: The correct answer is C, special visceral afferent cells. These cells are responsible for functions like taste and smell. In individuals with severe visual and auditory deficits, their other sensory abilities, such as touch, can be heightened. Special somatic afferent fibers (choice A) are involved in sensations like touch and vibration from the skin and muscles, but they are not specific to the face. General somatic afferents (choice B) transmit sensory information from the skin, muscles, and joints, but they are not specialized for the unique ability described. General visceral afferent neurons (choice D) are responsible for transmitting sensory information from internal organs, not relevant to the woman's ability to identify individuals through touch on her face.
2. A 25-year-old woman who works as an air traffic controller presents with facial pain and severe headache. She reports that she sometimes feels the pain in her neck or ear and that it is particularly bad during very busy times at the airport. What is the most likely diagnosis?
- A. Migraine headache
- B. Cluster headache
- C. Temporomandibular joint syndrome
- D. Sinus headache
Correct answer: C
Rationale: The most likely diagnosis for the 25-year-old woman who works as an air traffic controller and presents with facial pain and severe headache that sometimes radiates to her neck or ear, aggravated by stress, is Temporomandibular joint syndrome. This syndrome involves pain in the jaw joint and the muscles controlling jaw movement, which can radiate to the surrounding areas like the neck and ear. Stress and clenching of the jaw commonly exacerbate the symptoms. Migraine headache (choice A) typically presents with other symptoms like nausea, sensitivity to light or sound, and can be triggered by various factors, not just stress. Cluster headache (choice B) is characterized by severe, unilateral pain around the eye with associated autonomic symptoms. Sinus headache (choice D) is usually associated with sinus congestion or infection, presenting with facial pressure or pain, often worsened by bending forward.
3. In a postmenopausal woman, what condition can be prevented by administering estradiol (Estraderm)?
- A. Endometriosis
- B. Amenorrhea
- C. Osteoporosis
- D. Uterine cancer
Correct answer: C
Rationale: The correct answer is C: Osteoporosis. Estradiol, a form of estrogen, is used to prevent osteoporosis in postmenopausal women by maintaining bone density. Choice A, Endometriosis, is incorrect as estradiol is not used to prevent or treat this condition. Choice B, Amenorrhea, is not prevented by estradiol but rather may result from hormonal changes. Choice D, Uterine cancer, is not directly prevented by estradiol; in fact, long-term unopposed estrogen use can increase the risk of uterine cancer.
4. A patient is prescribed dutasteride (Avodart) for benign prostatic hyperplasia (BPH). What outcome should the nurse expect to observe if the drug is having the desired effect?
- A. Decreased size of the prostate gland
- B. Increased urinary output
- C. Increased urine flow
- D. Decreased blood pressure
Correct answer: A
Rationale: The correct answer is A: Decreased size of the prostate gland. Dutasteride is a medication used for BPH to reduce the size of the prostate gland, thereby improving urinary flow and decreasing symptoms. Choice B, increased urinary output, is incorrect as dutasteride primarily targets the size of the prostate gland rather than directly affecting urinary output. Choice C, increased urine flow, is related to the expected outcome of dutasteride therapy but is not as direct as the reduction in the size of the prostate gland. Choice D, decreased blood pressure, is not an expected outcome of dutasteride therapy for BPH.
5. After sustaining a concussion, a client experiences headache, vomiting, blurred vision, and loss of consciousness. What does this indicate?
- A. Increased intracranial pressure
- B. Lower extremity compartment syndrome
- C. Consuming too much food at once
- D. Improved kidney function
Correct answer: A
Rationale: The symptoms of headache, vomiting, blurred vision, and loss of consciousness following a concussion are indicative of increased intracranial pressure. These symptoms are commonly associated with intracranial pressure elevation, which can be dangerous and requires immediate medical attention. Lower extremity compartment syndrome is characterized by severe pain and swelling in the affected limb, not the symptoms mentioned. Consuming too much food at once may lead to digestive issues but does not correlate with the symptoms described. Improved kidney function would not manifest through the symptoms mentioned after a concussion.
