Adult Health 2 Final Exam

Correct Answer: C

Rationale: The correct answer is C. Substance abuse, particularly using shared inhalation equipment like needles and pipes for drug inhalation, significantly increases the risk of contracting HIV. Choice A, the 17-year-old with multiple sexual partners, poses a risk of HIV transmission through sexual contact, but it is lower compared to the direct risk associated with sharing drug paraphernalia. Choice B, the 34-year-old homosexual in a monogamous relationship, is at lower risk since being in a monogamous relationship reduces exposure to HIV. Choice D, the 45-year-old who received blood transfusions, is also at lower risk as blood transfusions are now screened for HIV, decreasing the likelihood of transmission through this route.

Correct Answer: D

Rationale: In advanced liver failure related to chronic alcoholism, ascites and edema occur due to multiple pathophysiological mechanisms. Portal hypertension contributes to the development of ascites by increasing pressure in the portal venous system. Sodium and water retention exacerbate fluid accumulation in the third space. Decreased serum albumin levels lead to reduced oncotic pressure, contributing to the movement of fluid into the interstitial spaces. Abnormal protein metabolism further disrupts fluid balance. Therefore, all of the options (A, B, and C) are correct in this scenario, making choice D the correct answer. Choices A, B, and C alone do not fully explain the comprehensive pathophysiological mechanisms involved in the development of ascites and edema in this clinical context.

Correct Answer: A

Rationale: After reconstitution, the concentration of cefazolin solution is calculated by dividing the total amount of drug (600 mg) by the total volume after reconstitution (2.5 mL). This gives 600 mg / 2.5 mL = 240 mg/mL. However, the question asks for the concentration in each milliliter of solution after reconstitution, so we need to consider the final volume of 2.5 mL. Therefore, 240 mg/mL * 2.5 mL = 600 mg, which means each milliliter contains 240 mg of cefazolin. Therefore, after reconstitution, there are 400 mg of cefazolin in each milliliter of solution. Choices B, C, and D are incorrect as they do not accurately reflect the concentration after reconstitution.

Correct Answer: B

Rationale: Choice B is the correct answer as it accurately explains that the letters T, N, and M in cancer staging represent tumor size, node involvement, and metastasis, respectively. Understanding this staging system helps the client comprehend the extent and severity of the disease. Choices A, C, and D are incorrect. Choice A has the correct information but is not the most precise response. Choice C is vague and does not directly address the client's need for clarification. Choice D offers further clarification without directly addressing the initial explanation provided by the healthcare provider.

Correct Answer: D

Rationale: The correct answer is D, Asterixis. Asterixis, also known as liver flap, is a sign of hepatic encephalopathy, a severe complication of liver disease that necessitates immediate attention. While jaundice (choice A), ascites (choice B), and spider angiomas (choice C) are common clinical findings in cirrhosis, asterixis is the most concerning due to its association with hepatic encephalopathy, which can lead to altered mental status and even coma. Jaundice, ascites, and spider angiomas are also important signs in cirrhosis, but asterixis indicates a more critical condition requiring urgent intervention.
