A nurse is caring for a client who has a prescription for warfarin. Which of the following laboratory tests should the nurse monitor?

Triiodothyronine

Blood urea nitrogen

Arterial blood gases

Prothrombin time

Answer and Explanation

The Correct Answer is D

Warfarin is an anticoagulant medication that works by inhibiting the synthesis of vitamin K-dependent clotting factors in the liver. Therefore, it is important to monitor the client's clotting ability to ensure that the medication is working properly and not causing any adverse eﬀects. The laboratory test that is used to monitor warfarin therapy is the prothrombin time (PT), which measures the time it takes for the blood to clot. The nurse should monitor the client's PT regularly and adjust the dosage of warfarin as necessary to maintain the therapeutic range. Option a (Triiodothyronine) is a thyroid hormone and is not directly related to warfarin therapy. Option b (Blood urea nitrogen) is a measure of kidney function and is also not directly related to warfarin therapy. Option c (Arterial blood gases) is a measure of oxygen and carbon dioxide levels in the blood and is not related to warfarin therapy.

Correct Answer is A

Explanation

Dementia is a condition characterized by a decline in cognitive function that aﬀects a person's ability to perform activities of daily living (ADLs). Memory loss is a common symptom of dementia, particularly in the early stages. Memory loss can disrupt a person's ability to carry out tasks they were previously able to do independently, such as dressing, bathing, and eating. Therefore, option A is the correct answer.

Option b, catatonia, is a condition characterized by a lack of movement or activity, which is not typically associated with dementia.

Option c, illusions, involve a misinterpretation of sensory information and may occur in some forms of dementia but are not a defining feature.

Option d, pressured speech, is a symptom commonly associated with mania or bipolar disorder but is not typically seen in dementia.

A. Decreased hemoglobin level B. Increased urinary output C. Decreased BUN level D. Increased weight of 0.91 kg (2 lb)

Correct Answer is B

Explanation

b. Increased urinary output.

Furosemide is a diuretic medication that helps remove excess ﬂuid from the body by increasing urine production and output. In a client with heart failure, one of the indicators that the medication is eﬀective is an increase in urinary output. This can help reduce ﬂuid buildup in the body, which can improve symptoms of heart failure.
