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 D

Explanation

Choice A. An embolic stroke is caused by an embolus, often a blood clot, that travels to the brain from another part of the body. It does not typically present with a sudden, severe headache.

Choice B. A thrombotic stroke occurs when a blood clot forms inside one of the brain's arteries. While it can cause a headache, it is not usually characterized by a sudden, severe headache.

Choice C. A transient ischemic attack (TIA) is often called a mini-stroke and symptoms are temporary. A sudden, severe headache is more indicative of a hemorrhagic stroke.

Choice D. A hemorrhagic stroke, which involves bleeding within the brain, is most likely to cause a sudden, severe headache, and can lead to seizures and changes in consciousness.

A. Pain relieved by food intake B. Pain radiating down the right arm C. Nausea and vomiting D. Weight loss

Correct Answer is A

Explanation

Choice A reason:Pain that is relieved by food intake is a classic symptom of duodenal ulcers, as eating can neutralize stomach acid temporarily, providing relief.

Choice B reason:Pain radiating down the right arm is not a typical symptom of a duodenal ulcer; it is more commonly associated with cardiac issues.

Choice C reason:Nausea and vomiting can be associated with duodenal ulcers, but they are not as specific as pain relief by food intake.

Choice D reason:Weight loss can occur with duodenal ulcers due to pain and eating avoidance, but the key symptom that relates directly to the ulcer is pain relief after food intake.
