A client is diagnosed with active tuberculosis and is started on medications. The nurse is aware that which parameter best indicates that the prescribed therapy has been effective? The client has:
a negative sputum culture.
decreased hemoptysis.
an improved chest x-ray.
a decreased rate of coughing.
The Correct Answer is A
Choice A Reason
A negative sputum culture is the most definitive indicator of the effectiveness of tuberculosis (TB) treatment. When a patient with active TB starts on medication, the goal is to eliminate the Mycobacterium tuberculosis bacteria from the body. A sputum culture that turns from positive to negative signifies that the bacteria have been eradicated from the respiratory secretions, indicating successful treatment.
Choice B Reason
While decreased hemoptysis (coughing up blood) is a positive sign and indicates an improvement in the patient's condition, it is not the most reliable parameter for determining the effectiveness of TB therapy. Hemoptysis may decrease as the patient's overall condition improves, but it does not confirm the eradication of the TB bacteria.
Choice C Reason
An improved chest x-ray can show a reduction in the lesions caused by TB, which is a good sign of recovery. However, chest x-rays cannot confirm whether the TB bacteria have been completely eliminated. They are more of a supportive indicator rather than a definitive one.
Choice D Reason
A decreased rate of coughing is another sign that the patient is responding to treatment, as coughing is a primary symptom of TB. However, similar to hemoptysis and chest x-ray improvements, a decrease in coughing does not necessarily mean that the TB bacteria have been fully cleared from the body.

Correct Answer is B
Explanation
Choice a reason:
A cream to soothe itching may be used if the client is experiencing pruritus, which can sometimes accompany biliary issues due to bile salts in the skin. However, pruritus is not a direct symptom of biliary colic, which is characterized primarily by pain.
Choice b reason:
Pain medication is the appropriate treatment for biliary colic. Biliary colic is caused by the temporary blockage of the bile duct by a gallstone, leading to intense pain in the upper right abdomen or the center of the abdomen. Pain relief is typically achieved with anti-inflammatory drugs or antispasmodics, and in some cases, opioids may be necessary.
Choice c reason:
An antibiotic would be prescribed if there was an infection, such as cholecystitis or cholangitis. Biliary colic itself does not necessarily indicate an infection unless accompanied by other symptoms such as fever or elevated white blood cell count.
Choice d reason:
A laxative is not typically used to treat biliary colic. While laxatives can help relieve constipation, biliary colic is a result of gallstones obstructing the bile duct, not bowel movement issues.
Correct Answer is D
Explanation
Choice a reason:
Warming the hands with water before testing is actually a recommended practice. It helps increase blood flow to the fingertips, making it easier to get a sufficient blood sample for testing. Cold hands can restrict blood flow, leading to difficulty in obtaining a blood sample and potentially inaccurate results.
Choice b reason:
Alternating fingers for blood glucose testing is also a recommended practice. It helps prevent soreness and calluses on the fingers from repeated pricks. Using different fingers or different sides of the same finger can help reduce pain and potential damage to the skin.
Choice c reason:
Choosing the center of the finger pad as a puncture site is not recommended. The sides of the fingertips are preferred because they have fewer nerve endings, making the process less painful. The center of the finger pad has a denser nerve supply and can lead to more discomfort during the test.
Choice d reason:
A random blood glucose result of 115 mg/dL is slightly above the normal range for non-diabetics, which is typically between 70 to 99 mg/dL when fasting. For someone with diabetes, this result might be considered within a target range, depending on individual treatment goals set by healthcare providers. However, it's important to note that a single glucose reading does not provide a complete picture of glucose control. An A1C test, which reflects average blood glucose levels over the past 2-3 months, is also necessary to assess overall glucose management.
