ATI Pathophysiology Exam
1. A client with a history of rheumatic fever presents with signs of heart failure. What is the likely underlying cause?
- A. Infective endocarditis
- B. Coronary artery disease
- C. Mitral valve stenosis
- D. Aortic regurgitation
Correct answer: C
Rationale: The correct answer is C: Mitral valve stenosis. Rheumatic fever can lead to scarring and thickening of the heart valves, often affecting the mitral valve. This stenosis can impede blood flow from the left atrium to the left ventricle, eventually causing heart failure. Choice A, infective endocarditis, is an infection of the endocardium, the inner lining of the heart chambers and valves, and is not directly related to rheumatic fever. Choice B, coronary artery disease, involves the obstruction of coronary arteries supplying the heart muscle with blood, leading to ischemia and not typically associated with rheumatic fever. Choice D, aortic regurgitation, is the backflow of blood from the aorta to the left ventricle and is not a common consequence of rheumatic fever.
2. A patient suffers from dysmenorrhea. Which oral medication will be prescribed that has the ability to provide physiological actions on the neuroendocrine control of ovarian function?
- A. Estrogen
- B. Progestins
- C. Naproxen
- D. Ibuprofen
Correct answer: B
Rationale: Progestins are prescribed for dysmenorrhea as they help reduce menstrual pain by inhibiting ovulation and decreasing the production of prostaglandins. Estrogen (Choice A) is not typically used alone in dysmenorrhea treatment as it can worsen symptoms. Naproxen (Choice C) and Ibuprofen (Choice D) are nonsteroidal anti-inflammatory drugs (NSAIDs) commonly used to relieve pain associated with dysmenorrhea, but they do not directly affect the neuroendocrine control of ovarian function like progestins do.
3. In a patient with HIV infected with Mycobacterium avium complex from an indoor pool, which of the following medications is the recommended treatment for MAC?
- A. Clarithromycin
- B. Isoniazid (INH)
- C. Rifabutin
- D. Azithromycin
Correct answer: A
Rationale: The correct answer is Clarithromycin. Clarithromycin is one of the recommended medications for treating Mycobacterium avium complex (MAC) infections in patients with HIV. It is a macrolide antibiotic that is effective against MAC. Isoniazid (INH) is used to treat tuberculosis, not MAC. Rifabutin is another medication used in the treatment of MAC infections, but clarithromycin is preferred as a first-line agent. Azithromycin is also used in the treatment of MAC infections; however, clarithromycin is more commonly recommended due to its efficacy and safety profile.
4. A student is feeling inside her backpack to find her mobile phone. There are a number of other items in the bag other than the phone. The nurse knows that which term best describes one's ability to sense the shape and size of an object in the absence of visualization?
- A. Stereognosis
- B. Graphesthesia
- C. Proprioception
- D. Kinesthesia
Correct answer: A
Rationale: Stereognosis is the correct answer. It refers to the ability to recognize objects by touch, specifically determining their shape and size without relying on visual cues. Graphesthesia, on the other hand, is the ability to recognize symbols or numbers traced on the skin. Proprioception involves the awareness of body position and movement. Kinesthesia relates to the perception of body movement.
5. 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 characterized by normochromic and normocytic red blood cells. In chronic inflammation, the body typically produces enough red blood cells, but they are often smaller and paler than normal (normocytic and normochromic). Choices A, B, and C are incorrect because hypochromic and microcytic, hypochromic and macrocytic, and normochromic and microcytic anemias are not typically associated with chronic inflammation.
