A client is admitted to the hospital with suspected rheumatic endocarditis. Which of the following laboratory tests would assist in confirming the diagnosis?

Liver enzymes

Serum albumin

Throat culture

Arterial blood gases

Answer and Explanation

The Correct Answer is C

Title: Choice A reason: Liver enzymes Liver enzymes are proteins that speed up chemical reactions in your body. They include alanine transaminase (ALT), aspartate transaminase (AST), and alkaline phosphatase (ALP). High levels of liver enzymes in the blood can indicate liver disease. However, rheumatic endocarditis is a heart condition, not a liver condition. Therefore, while liver enzymes are important for diagnosing liver conditions, they would not assist in confirming a diagnosis of rheumatic endocarditis.

Title: Choice B reason: Serum albumin Serum albumin is a type of protein that your liver and kidneys produce to help your body maintain fluid balance and function. Low or high albumin levels can indicate liver disease, kidney disease, or nutritional deficiency. However, rheumatic endocarditis is a heart condition, not a liver or kidney condition. Therefore, while serum albumin is important for diagnosing liver and kidney conditions, it would not assist in confirming a diagnosis of rheumatic endocarditis.

Title: Choice C reason: Throat culture A throat culture is a lab test used to find and identify germs in the back of your mouth that are making you sick. It can diagnose infections like strep throat, gonorrhea, thrush, diphtheria, and pertussis. Rheumatic endocarditis is often caused by a streptococcal infection, which can be identified through a throat culture. Therefore, a throat culture would assist in confirming a diagnosis of rheumatic endocarditis.

Title: Choice D reason: Arterial blood gases An arterial blood gas (ABG) test measures the levels of oxygen and carbon dioxide in your blood as well as the pH balance in your blood. It helps diagnose and monitor conditions that affect your respiratory, circulatory, and metabolic systems. However, rheumatic endocarditis is a heart condition that is often caused by a bacterial infection. Therefore, while an ABG test is important for diagnosing conditions that affect your respiratory, circulatory, and metabolic systems, it would not assist in confirming a diagnosis of rheumatic endocarditis.

Correct Answer is ["60"]

Explanation

- Step 1: Identify the required dose in grams. The client is scheduled to receive 30 grams of lactulose.

- Step 2: Identify the concentration of the available solution. The available solution contains 5 grams of lactulose per 10 mL.

- Step 3: Calculate the volume of solution needed to deliver the required dose. We can set up a proportion to solve for this:

- 5 grams is to 10 mL as 30 grams is to X mL.

- In other words, 5 g : 10 mL = 30 g : X mL.

- Step 4: Solve for X using cross-multiplication and division:

- Cross-multiplication gives us: 5 g × X mL = 30 g × 10 mL.

- Simplifying this gives us: 5X = 300.

- Dividing both sides by 5 gives us: X = 300 ÷ 5.

- Calculating the division gives us: X = 60.

60 mL of the lactulose solution should be poured into the medication cup to administer the required dose of 30 grams.

A. Weight gain B. Use of alcohol C. Abdominal pain relieved with food or antacids D. Exposure to occupational chemicals

Correct Answer is B

Explanation

Choice A reason: Weight gain is not typically a direct cause of chronic pancreatitis. While obesity can be a risk factor for developing pancreatitis, it is not considered a primary cause.

Choice B reason: The use of alcohol is the most common cause of chronic pancreatitis. Long-term alcohol misuse can lead to the development of chronic pancreatitis, accounting for about 70% of cases³.

Choice C reason: Abdominal pain that is relieved with food or antacids is more indicative of conditions like peptic ulcers rather than chronic pancreatitis.

Choice D reason:Exposure to occupational chemicals has not been established as a primary cause of chronic pancreatitis. While certain toxins can affect the pancreas, they are not a common cause of chronic pancreatitis.
