A nurse is administering furosemide IV bolus to a client who has fluid volume excess.

The nurse should recognize which of the following findings as an indication that the medication has been effective?

Answer:D. Troponin T test

Rationale:

A. Creatine kinase (CK) test: While creatine kinase isoenzymes, including CK-MB, can be elevated following myocardial infarction (MI), they are not specific to cardiac muscle injury. CK is found in various tissues throughout the body, so elevated levels can also indicate damage to skeletal muscle or brain tissue, among other sources.

B. Creatine kinase-myocardial band (CK-MB) test: CK-MB is a cardiac-specific isoform of creatine kinase, and elevated levels can indicate myocardial injury, particularly in the context of an acute MI. However, troponin T is a more sensitive and specific marker for myocardial injury.

C. Brain natriuretic peptide (BNP) test: Brain natriuretic peptide is primarily used in the diagnosis and management of heart failure. While elevated BNP levels can indicate heart muscle strain or stress, they are not specific markers for acute myocardial infarction or early injury to the cardiac muscle.

D. Troponin T test: This is the correct answer. Troponin T is a highly specific marker for cardiac muscle injury. Elevated troponin levels can be detected within hours of myocardial infarction and persist for several days, making it an essential tool in the diagnosis of acute coronary syndromes, including myocardial infarction. Troponin T is considered one of the gold standard biomarkers for detecting early injury to the cardiac muscle.

The correct answer is choice C. Taking a hot shower in the morning can help decrease stiffness and improve joint mobility for people with rheumatoid arthritis. This is one of the self-management strategies that can reduce pain and disability.

Choice A is wrong because applying cold packs directly on the skin of the affected joints can cause vasoconstriction and increase inflammation.

Cold therapy should be used with caution and with a barrier between the skin and the ice pack.

Choice B is wrong because biological response modifiers are not used to prevent infection, but to reduce inflammation and slow down joint damage in rheumatoid arthritis.

These medications can actually increase the risk of infection by suppressing the immune system.

Choice D is wrong because clustering physical activities during the day can cause fatigue and joint stress for people with rheumatoid arthritis.

It is better to pace activities throughout the day and take frequent breaks to rest the joints.

Normal ranges for rheumatoid arthritis are based on the disease activity score (DAS), which measures the number of swollen and tender joints, the level of inflammation in the blood, and the patient’s global assessment of health. A DAS below 2.6 indicates remission, a DAS between 2.6 and 3.2 indicates low disease activity, a DAS between 3.2 and 5.1 indicates moderate disease activity, and a DAS above 5.1 indicates high disease activity.
