Potassium 3.1 mEq/L

Prothrombin time/International normalized ratio (INR) 2.2

Urine output: 600 mL

Potassium 3.1 mEq/L

Prothrombin time/INR 2.2

Urine output: 600 mL

Answer and Explanation

The Correct Answer is {"A":{"answers":"B"},"B":{"answers":"C"},"C":{"answers":"A"}}

Based on the question and the known effects of furosemide, here’s how each assessment finding can be categorized:

Potassium 3.1 mEq/L: This is a non-therapeutic side effect. Furosemide is a diuretic that increases the excretion of water, sodium, and potassium from the body. This can lead to hypokalemia, or low potassium levels.
Prothrombin time/INR 2.2: This is likely an unrelated finding. Furosemide does not typically affect prothrombin time or INR. However, the patient is also taking warfarin, which is an anticoagulant known to increase INR.
Urine output: 600 mL: This is a therapeutic result. Furosemide works by increasing the amount of urine the body makes, which helps reduce swelling and symptoms of fluid retention.

Correct Answer is C

Explanation

Choice A rationale

There is no indication that Patient D, who is scheduled for an appendectomy and has a white blood cell (WBC) count of 14,000 mm² (14 x 10°/L), needs to be transferred to an isolation room 24 hours prior to surgery.

Choice B rationale

Patient A, diagnosed with emphysema and has an oxygen saturation of 94% on room air, does not necessarily need an increase in oxygen. An oxygen saturation of 94% is within normal limits.

Choice C rationale

Patient B, who is postoperative with a hemoglobin level of 8.2 mg/dL (82 g/L), may require a blood transfusion. A hemoglobin level of 8.2 mg/dL is low, and having packed cells available is a prudent measure.

Choice D rationale

Patient C, newly admitted with a potassium level of 3.8 mEq/L (3.8 mmol/L), has a normal potassium level. Including a banana in the breakfast tray is not a priority.

A. The right foot is cool to the touch and appears pale and blanched. B. The pressure dressing at the right femoral area is moist and oozing blood. C. The client’s blood pressure trend is downward, and the pulse is rapid and irregular. D. The pulse distal to the femoral artery is weaker on the left foot than the right foot.

Correct Answer is A

Explanation

Choice A rationale

The right foot being cool to the touch and appearing pale and blanched is a classic sign of arterial obstruction. After a cardiac catheterization via the right femoral artery, it’s possible that a clot or other obstruction could have formed, impeding blood flow to the right foot. This would cause the foot to become cool and pale due to lack of warm, oxygenated blood.

Choice B rationale

While a moist and oozing pressure dressing at the right femoral area could indicate a problem such as bleeding from the catheter insertion site, it does not specifically indicate arterial obstruction.

Choice C rationale

A downward trend in blood pressure and a rapid, irregular pulse could indicate many different problems, including shock, heart failure, or arrhythmias. However, these symptoms are not specific to arterial obstruction.

Choice D rationale

A weaker pulse distal to the femoral artery on the left foot compared to the right foot could indicate a problem with circulation to the left foot, but it does not indicate an obstruction in the right femoral artery.
