A client is diagnosed with atrial fibrillation and has experienced a transient ischemic attack (TI

A diuretic medication

An oral anticoagulant medication

A beta blocker medication

An antihyperuricemic medication

Answer and Explanation

The Correct Answer is B

Choice A reason:

A diuretic medication is generally used to remove excess fluid from the body and treat conditions such as hypertension and heart failure. While it can be part of the management plan for atrial fibrillation if there is fluid overload, it is not specifically used to prevent thromboembolic events like TIA, which are a major concern in atrial fibrillation patients.

Choice B reason:

An oral anticoagulant medication is the most appropriate choice for a patient with atrial fibrillation who has experienced a TIA. Anticoagulants, such as warfarin or newer direct oral anticoagulants (DOACs), are used to prevent blood clots from forming and reduce the risk of stroke and other thromboembolic events. This choice directly addresses the primary goal of reducing the risk of future TIAs or strokes in patients with atrial fibrillation.

Choice C reason:

A beta blocker medication can be useful in managing atrial fibrillation by controlling the heart rate and reducing the risk of symptomatic episodes. However, beta blockers do not address the risk of thromboembolism, which is critical in the context of a patient with a history of TIA. Thus, while beneficial for rate control, they do not serve the primary purpose of preventing strokes in this scenario.

Choice D reason:

An antihyperuricemic medication is used to lower uric acid levels and treat conditions like gout. It is not relevant to the management of atrial fibrillation or the prevention of thromboembolic events. Including this option does not align with the clinical needs of a patient with atrial fibrillation and a history of TIA.

Correct Answer is D

Explanation

Choice A reason:

Steatorrhea is the presence of excess fat in the stool, which indicates malabsorption issues. However, it is not what a guaiac stool test is designed to detect. Specialized fat stains and tests are used to identify steatorrhea.

Choice B reason:

Bacteria presence in stool is usually evaluated through stool culture tests, not the guaiac stool test. A stool culture helps identify bacterial infections in the gastrointestinal tract.

Choice C reason:

Parasites in stool are detected using ova and parasite (O&P) exams, not the guaiac stool test. The O&P exam identifies microscopic parasites and their eggs.

Choice D reason:

The guaiac stool test is used to detect the presence of occult (hidden) blood in the stool. It helps identify gastrointestinal bleeding that is not visible to the naked eye, which can be a sign of conditions such as ulcers, polyps, or colorectal cancer.

A. WBC count 8,000/mm³ B. hemoglobin 16 g/dL C. serum albumin 3.2 g/dL D. INR 0.9

Correct Answer is C

Explanation

Choice A reason: A WBC count of 8,000/mm³ falls within the normal range (4,000-11,000/mm³) and does not indicate a specific risk for delayed wound healing. It helps assess the immune response but is not a direct marker for nutrition or tissue repair.

Choice B reason: A hemoglobin level of 16 g/dL is within the normal range (13.8-17.2 g/dL for men, 12.1-15.1 g/dL for women) and indicates adequate oxygen-carrying capacity. While essential for overall health, it does not directly correlate with the risk of delayed wound healing in this context.

Choice C reason: This is the correct answer. Serum albumin levels are a marker of nutritional status. A level of 3.2 g/dL is on the lower side of the normal range (3.5-5.0 g/dL) and indicates potential malnutrition, which can impair wound healing by limiting the availability of necessary proteins and nutrients for tissue repair.

Choice D reason: An INR (International Normalized Ratio) of 0.9 is within the normal range (0.8-1.2) and reflects normal blood clotting. While important for understanding coagulation status, it does not indicate a direct risk for delayed wound healing related to nutrition or protein levels.
