A nurse performs Homans maneuver by flexing the knee and sharply dorsiflexing the foot. What response indicates a positive Homans sign?
Cramping of the toes
Blanching of the sole
Resisting dorsiflexion
Pain in the calf area .
The Correct Answer is D
Choice A rationale
Cramping of the toes is not typically associated with a positive Homans sign. Homans sign is a test used to check for deep vein thrombosis (DVT), a blood clot in a deep vein of the leg. While cramping can occur with DVT, it is not specific to this condition and can occur with many other conditions.
Choice B rationale
Blanching of the sole is not associated with a positive Homans sign. Blanching, or whitening of the skin, can occur with various conditions, but it is not a typical sign of DVT45.
Choice C rationale
Resisting dorsiflexion is not a typical response indicating a positive Homans sign. While pain or resistance during dorsiflexion of the foot can occur with various conditions, it is not a specific sign of DVT45.
Choice D rationale
Pain in the calf area during dorsiflexion of the foot (Homans sign) can indicate a positive sign for DVT. However, it’s important to note that Homans sign is not a reliable or definitive test for DVT. Other diagnostic tests, such as ultrasound, are needed to confirm the diagnosis.

Correct Answer is C
Explanation
Choice A rationale
This sequence is incorrect because it suggests that blood goes from the lungs to the pulmonary artery, which is not accurate. The pulmonary artery carries deoxygenated blood from the heart to the lungs.
Choice B rationale
This sequence is incorrect because it suggests that blood goes from the pulmonary vein to the lungs, which is not accurate. The pulmonary vein carries oxygenated blood from the lungs to the heart.
Choice C rationale
This sequence correctly describes the direction of blood flow through the heart and lungs. Deoxygenated blood enters the right atrium, goes to the right ventricle, then is sent to the lungs via the pulmonary artery. After picking up oxygen in the lungs, the blood returns to the heart via the pulmonary vein, entering the left atrium, then the left ventricle, from where it is pumped out to the rest of the body.
Choice D rationale
This sequence is incorrect because it suggests that blood goes from the pulmonary vein to the pulmonary artery, which is not accurate. The pulmonary vein carries oxygenated blood from the lungs to the heart, and the pulmonary artery carries deoxygenated blood from the heart to the lungs.
Correct Answer is A
Explanation
Choice A rationale
Left heart failure is a common cause of right heart failure. When the left side of the heart is unable to pump blood efficiently, it can cause increased pressure in the lungs, which can then lead to right heart failure.
Choice B rationale
Pericarditis, an inflammation of the sac-like covering around the heart, is not typically a direct cause of right heart failure.
Choice C rationale
While hypertension, or high blood pressure, can contribute to heart failure, it typically affects the left side of the heart more than the right.
Choice D rationale
Acute pneumonia, an infection that inflames the air sacs in one or both lungs, is not typically a direct cause of right heart failure.
