Which of the following is a rationale for prescribing total parenteral nutrition (TPN) for a patient with inflammatory bowel disease (IBD)?
To provide essential nutrients while allowing the bowel to rest and heal.
To reduce inflammation and control symptoms of IBD.
To stimulate the bowel and promote regular bowel movements.
To prevent malnutrition and promote weight gain.
The Correct Answer is A
Choice A rationale
Total parenteral nutrition (TPN) provides essential nutrients intravenously, allowing the bowel to rest and heal, which is important in the management of inflammatory bowel disease (IBD).
Choice B rationale
While reducing inflammation and controlling symptoms are important goals in IBD management, TPN is primarily used to provide nutrition and allow the bowel to rest.
Choice C rationale
Stimulating the bowel is not the purpose of TPN. TPN is used to give the digestive tract a break while ensuring the patient receives necessary nutrients.
Choice D rationale
Preventing malnutrition and promoting weight gain are secondary benefits of TPN, but the primary rationale is to provide nutrients while allowing the bowel to rest and heal.

Correct Answer is D
Explanation
Choice A rationale
A complete blood count (CBC) can provide general information about the body's response to an MI, such as white blood cell count, but it is not definitive for diagnosing an MI.
Choice B rationale
A lipid profile measures cholesterol levels and helps assess cardiovascular risk, but it is not useful for diagnosing an acute MI.
Choice C rationale
An electrocardiogram (ECG) is essential for diagnosing an MI as it shows the heart's electrical activity and can indicate ischemia or infarction.
Choice D rationale
Troponin levels are the most specific and sensitive markers for myocardial infarction. Elevated troponin levels confirm heart muscle damage due to an MI, making it the definitive test.
Correct Answer is B
Explanation
Choice A rationale
A complete blood count (CBC) can provide information about the client's overall health and presence of infection, but it does not specifically address the potential underlying cause related to the urinary system.
Choice B rationale
Urinalysis with culture is the most relevant diagnostic test for evaluating the underlying cause of fever, chills, and severe left costovertebral pain. These symptoms suggest a possible urinary tract infection or pyelonephritis, which can be confirmed with urinalysis and culture.
Choice C rationale
A chest X-ray would not be the priority in this scenario as the symptoms suggest a urinary tract issue rather than a respiratory problem. A chest X-ray is more useful for assessing lung conditions.
Choice D rationale
A CT scan of the abdomen and pelvis can be helpful in evaluating the extent of a urinary tract infection or identifying other causes of abdominal pain, but it is typically not the first-line diagnostic test. Urinalysis with culture is more specific for identifying urinary infections. .
