A nurse is caring for a client who reports an area of redness, warmth, tenderness, and pain in the right calf.

The nurse anticipates which of the following orders when notifying the provider of this finding?

Obtain impedance plethysmography.

Apply cold therapy to the affected leg.

Obtain a venous duplex ultrasound.

Monitor Homan's sign.

Answer and Explanation

The Correct Answer is C

Choice A rationale:
Impedance plethysmography is a test that uses electrical signals to measure blood flow and can be used to detect deep vein thrombosis (DVT). However, it is not the first-line diagnostic tool for DVT.
Choice B rationale:
Cold therapy can help reduce inflammation and pain, but it is not a diagnostic measure for DVT.
Choice C rationale:
Venous duplex ultrasound is the most common test used to diagnose DVT. It uses sound waves to create pictures of the blood flowing through the veins in the leg.
Choice D rationale:
Homan’s sign is a physical examination finding that was traditionally used to diagnose DVT, but it is not reliable or specific.

Correct Answer is D

Explanation

Choice A rationale:
Apneustic respirations are characterized by prolonged inspiratory phase with shortened expiratory phase, not alternating periods of hyperventilation and apnea.
Choice B rationale:
Stridor is a high-pitched, wheezing sound caused by disrupted airflow, not a pattern of breathing.
Choice C rationale:
Kussmaul respirations are deep and labored breathing pattern often associated with severe metabolic acidosis, particularly diabetic ketoacidosis, not alternating periods of hyperventilation and apnea.
Choice D rationale:
Cheyne-Stokes respirations are characterized by alternating periods of hyperventilation and apnea.

A. pH 7.25, HCO3- 19 mEq/L, PaCO2 30 mm Hg. B. pH 7.50, HCO3- 20 mEq/L, PaCO2 32 mm Hg. C. pH 7.55, HCO3- 30 mEq/L, PaCO2 31 mm Hg. D. pH 7.30, HCO3- 26 mEq/L, PaCO2 50 mm Hg.

Correct Answer is A

Explanation

Choice A rationale:
These values indicate metabolic acidosis, which is common in clients with chronic kidney disease. The kidneys are unable to excrete hydrogen ions and reabsorb bicarbonate, leading to a low pH and low bicarbonate levels.
Choice B rationale:
These values indicate alkalosis, not typically associated with chronic kidney disease. The pH is high, indicating a basic or alkaline state, and the bicarbonate level is normal.
Choice C rationale:
These values indicate metabolic alkalosis, which is not typically seen in clients with chronic kidney disease. The pH and bicarbonate levels are both high.
Choice D rationale:
These values indicate respiratory acidosis, not typically associated with chronic kidney disease. The high PaCO2 level indicates that the lungs are not effectively eliminating CO2, leading to acidosis.
