1. Anemia of chronic inflammation is generally classified as:
- A. Hypochromic and microcytic.
- B. Hypochromic and macrocytic.
- C. Normochromic and microcytic.
- D. Normochromic and normocytic.
Correct answer: D
Rationale: Anemia of chronic inflammation is typically characterized by normochromic (normal hemoglobin content) and normocytic (normal cell size) red blood cells. Choice A, hypochromic and microcytic, is incorrect because hypochromic refers to reduced hemoglobin content and microcytic refers to smaller than normal red blood cells, which are not typically seen in anemia of chronic inflammation. Choice B, hypochromic and macrocytic, is also incorrect as macrocytic refers to larger than normal red blood cells. Choice C, normochromic and microcytic, is incorrect because microcytic red blood cells are smaller than normal. Therefore, the correct classification for anemia of chronic inflammation is normochromic and normocytic.
2. What is the etiology and most likely treatment for myasthenia gravis in a 22-year-old female college student?
- A. Autoimmune destruction of skeletal muscle cells; treatment with intensive physical therapy and anabolic steroids.
- B. A decline in functioning acetylcholine receptors; treatment with corticosteroids and intravenous immunoglobulins.
- C. Cerebellar lesions; surgical and immunosuppressive treatment.
- D. Excess acetylcholinesterase production; treatment with thymectomy.
Correct answer: B
Rationale: Myasthenia gravis is characterized by a decline in functioning acetylcholine receptors rather than autoimmune destruction of skeletal muscle cells (Choice A), cerebellar lesions (Choice C), or excess acetylcholinesterase production (Choice D). The most likely treatment for myasthenia gravis involves corticosteroids to reduce inflammation and intravenous immunoglobulins to block the antibodies attacking acetylcholine receptors. Intensive physical therapy and anabolic steroids are not primary treatments for myasthenia gravis.
3. A male patient is receiving androgen therapy for hypogonadism. What adverse effect should the nurse monitor for during this therapy?
- A. Increased risk of bone fractures
- 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. Androgen therapy can lead to an increased risk of cardiovascular events like heart attacks and strokes, especially in older patients. Monitoring for signs and symptoms of cardiovascular issues is essential during this therapy. Choices A, C, and D are incorrect because androgen therapy is not typically associated with an increased risk of bone fractures, liver dysfunction, or prostate cancer.
4. A male patient with erectile dysfunction is prescribed sildenafil (Viagra). What specific instruction should the nurse provide to ensure the safe use of this medication?
- A. Take the medication with food to prevent nausea.
- B. Avoid taking nitrates while on this medication.
- C. Take the medication at bedtime to ensure absorption during sleep.
- D. Take the medication with milk to enhance absorption.
Correct answer: B
Rationale: The correct instruction the nurse should provide is to avoid taking nitrates while on sildenafil (Viagra). Combining sildenafil with nitrates can result in severe hypotension due to additive vasodilatory effects. Choice A is incorrect because sildenafil can be taken with or without food. Choice C is incorrect as there is no specific requirement to take sildenafil at bedtime. Choice D is incorrect as taking sildenafil with milk has not been shown to enhance its absorption.
5. A patient presents with a chronic cough, night sweats, and weight loss. A chest X-ray reveals upper lobe cavitary lesions. Which of the following is the most likely diagnosis?
- A. Tuberculosis
- B. Pneumonia
- C. Lung cancer
- D. Sarcoidosis
Correct answer: A
Rationale: The correct answer is A: Tuberculosis. Cavitary lesions in the upper lobes are classic findings seen in tuberculosis. This infectious disease commonly presents with symptoms such as chronic cough, night sweats, and weight loss. Pneumonia (Choice B) typically does not present with cavitary lesions on chest X-ray. Lung cancer (Choice C) may present with similar symptoms but is less likely to cause cavitary lesions in the upper lobes. Sarcoidosis (Choice D) usually presents with bilateral hilar lymphadenopathy and non-caseating granulomas, different from the cavitary lesions described in the case.
