ATI Pathophysiology Exam 1

1. Which symptoms are typical of asthma?

Correct answer: C

Rationale: The correct answer is C: Wheezing and dyspnea are typical symptoms of asthma. Wheezing refers to a high-pitched whistling sound while breathing, and dyspnea is shortness of breath. These symptoms are classic signs of airway obstruction and inflammation seen in asthma. Choice A is incorrect as chest pain is not a typical symptom of asthma, though coughing can occur. Choice B is incorrect as diarrhea is not associated with asthma, while wheezing is a common symptom. Choice D is incorrect as tachypnea (rapid breathing) can occur in asthma, but constipation is not a typical symptom.

2. A patient receiving isoniazid (INH) and rifampin (Rifadin) has a decreased urinary output and decreased sensation in his great toes. Which laboratory values should be assessed?

Correct answer: C

Rationale: In a patient receiving isoniazid (INH) and rifampin (Rifadin) with symptoms of decreased urinary output and decreased sensation in great toes, assessing urine culture and sensitivity is crucial. These symptoms could indicate peripheral neuropathy, a known side effect of isoniazid, and rifampin can cause renal toxicity. Checking for any urinary tract infection or drug-induced nephrotoxicity is important. Choices A, B, and D are incorrect as they do not directly address the symptoms presented by the patient or the potential side effects of the medications mentioned.

3. A client with a history of rheumatic fever presents with signs of heart failure. What is the likely underlying cause?

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.

4. A 9-year-old girl has a diffuse collection of symptoms that are indicative of deficits in endocrine and autonomic nervous system control. She also suffers from persistent fluid and electrolyte imbalances. On which aspect of the nervous system listed below would her health care providers focus their diagnostic efforts?

Correct answer: C

Rationale: The correct answer is C: The hypothalamus. The hypothalamus plays a central role in regulating endocrine and autonomic functions, including fluid and electrolyte balance. In this case, the girl's symptoms of deficits in endocrine and autonomic nervous system control, along with fluid and electrolyte imbalances, point towards dysfunction in the hypothalamus. Choices A, B, and D are incorrect because the thalamus is mainly involved in sensory relay, the pituitary gland regulates various hormones but is controlled by the hypothalamus, and the midbrain is responsible for motor control and arousal, not endocrine or autonomic functions.

5. Ivermectin (Stromectol) appears on a list of a patient's recent medications. The nurse who is reviewing the medications is justified in suspecting that the patient may have been receiving treatment for a parasitic infection with

Correct answer: C

Rationale: Ivermectin (Stromectol) is commonly used to treat parasitic infections, particularly Strongyloides stercoralis. This parasitic infection is known to respond well to Ivermectin therapy. Entamoeba histolytica causes amoebiasis and is typically treated with antiprotozoal drugs like metronidazole, not Ivermectin. Giardia lamblia is a protozoan parasite causing giardiasis, which is usually treated with medications like metronidazole or tinidazole, not Ivermectin. Plasmodium falciparum is a malaria-causing parasite and is not treated with Ivermectin but with antimalarial medications like chloroquine or artemisinin-based combination therapies.
