Pathophysiology Practice Exam
1. A 60-year-old male patient presents with severe and persistent pain in his left leg and hip that worsens with activity. After further evaluation, the patient is diagnosed with osteosarcoma. Which of the following is true about osteosarcoma?
- A. It is more common in children and young adults.
- B. Early diagnosis improves the prognosis.
- C. It is frequently located in the leg bones.
- D. All of the above are true.
Correct answer: D
Rationale: Osteosarcoma is a type of bone cancer that can be found in any bone but is most commonly located in the long bones of the legs. While it is more prevalent in children and young adults, it can also occur in older individuals like the 60-year-old male patient in this case. Early diagnosis is crucial for a better prognosis in osteosarcoma cases. Therefore, all the statements provided are true regarding osteosarcoma, making option D the correct answer. Option A is accurate as osteosarcoma is more common in children and young adults. Option B is correct as early diagnosis improves the prognosis. Option C is accurate as osteosarcoma is frequently located in the leg bones.
2. A nurse is teaching a patient about the use of raloxifene (Evista) for the prevention of osteoporosis. What is the primary therapeutic action of this medication?
- A. It decreases the absorption of calcium from the intestines.
- B. It decreases bone resorption and increases bone density.
- C. It increases the excretion of calcium through the kidneys.
- D. It stimulates the formation of new bone.
Correct answer: B
Rationale: The correct answer is B. Raloxifene, a selective estrogen receptor modulator (SERM), works by decreasing bone resorption and increasing bone density. This action helps in preventing osteoporosis by maintaining bone strength. Choice A is incorrect as raloxifene does not affect the absorption of calcium from the intestines. Choice C is incorrect as raloxifene does not increase the excretion of calcium through the kidneys. Choice D is incorrect as raloxifene does not directly stimulate the formation of new bone; instead, it primarily works by reducing bone loss.
3. A male patient is being treated with testosterone gel for hypogonadism. What important instruction should the nurse provide?
- A. Apply the gel to the face and neck for maximum absorption.
- B. Apply the gel to the chest or upper arms and allow it to dry completely before dressing.
- C. Apply the gel to the scalp and back.
- D. Apply the gel to the genitals for improved results.
Correct answer: B
Rationale: The correct instruction for applying testosterone gel is to apply it to the chest or upper arms and allow it to dry completely before dressing. This is important to prevent the transfer of the medication to others. Applying it to the face and neck (Choice A) is incorrect as these areas are not recommended. Similarly, applying it to the scalp and back (Choice C) or the genitals (Choice D) is also incorrect and can lead to inappropriate absorption or undesirable effects.
4. A male patient with hypogonadism is receiving testosterone therapy. What is the most serious adverse effect the nurse should monitor for?
- A. Increased risk of breast cancer
- B. Increased risk of cardiovascular events
- C. Increased risk of liver dysfunction
- D. Increased risk of prostate cancer
Correct answer: B
Rationale: The correct answer is B: Increased risk of cardiovascular events. Testosterone therapy can lead to an increased risk of cardiovascular events such as heart attacks and strokes, especially in older patients. Monitoring for signs and symptoms of cardiovascular issues is crucial when administering testosterone therapy. Choices A, C, and D are incorrect because testosterone therapy does not typically lead to an increased risk of breast cancer, liver dysfunction, or prostate cancer.
5. The nurse is preparing to administer a vaccine to a newborn. Before administering the vaccine, the nurse should
- A. warm the vaccine to room temperature.
- B. gently cleanse the chosen injection site.
- C. check the infant's temperature.
- D. administer the full dose at a single injection site.
Correct answer: C
Rationale: Before administering a vaccine to a newborn, it is essential for the nurse to check the infant's temperature. This is important to ensure that the newborn does not have a fever, which could indicate an underlying infection or illness. Warming the vaccine to room temperature is not necessary and could be harmful. Vigorously massaging the injection site is not recommended as it can cause discomfort and tissue damage. Dividing the dose for administration to three injection sites is not standard practice for vaccine administration to a newborn.
