The nurse is checking the range of motion in a patient's knee and knows that the knee is capable of which movement(s)?

Flexion & extension.

Inversion & eversion.

Supination & pronation.

Circumduction & rotation.

Answer and Explanation

The Correct Answer is A

Choice A rationale

The knee joint, a modified hinge joint, primarily facilitates movement within the sagittal plane. Flexion involves decreasing the angle between the femur and tibia, bending the knee, while extension involves increasing this angle, straightening the knee. These movements are achieved through the coordinated action of muscles like the quadriceps femoris and hamstrings, acting on the condyles of the femur and tibia.

Choice B rationale

Inversion and eversion are movements specific to the ankle and foot. Inversion involves turning the sole of the foot inward, towards the midline of the body, while eversion involves turning the sole of the foot outward, away from the midline. These movements are mediated by the subtalar and transverse tarsal joints, not the knee.

Choice C rationale

Supination and pronation are rotatory movements primarily associated with the forearm and hand. Supination involves rotating the forearm so the palm faces anteriorly or superiorly, while pronation involves rotating it so the palm faces posteriorly or inferiorly. These actions are controlled by muscles acting on the radius and ulna, not the knee joint.

Choice D rationale

Circumduction is a complex movement combining flexion, extension, abduction, and adduction, commonly seen in ball-and-socket joints like the shoulder or hip. Rotation, where a bone pivots around its own longitudinal axis, is also more prominent in these joints. While the knee has minimal rotational capability when flexed, it's not a primary movement.

Correct Answer is C

Explanation

Choice A rationale

While palpation is a critical skill, this statement does not directly complete the given sentence which defines palpation as a technique. The existing sentence establishes the "what" of palpation, and the completion should elaborate on "how" it's performed or its direct characteristics.

Choice B rationale

Palpation certainly helps identify abnormalities, but this statement describes a benefit or outcome of the technique, not the core method itself as described in the initial sentence. The sentence sets up the physical action, not its diagnostic utility.

Choice C rationale

This choice logically completes the sentence by explaining the *methodology* of palpation, directly following the description of the senses involved and what is being assessed. It specifies that the technique involves "careful and systematic touching of the body," which directly relates to the physical act of assessment.

Choice D rationale

Proper palpation technique ensures accurate examinations, but this statement focuses on the *quality* of the technique rather than describing the technique itself. The initial sentence defines the technique; the completion should expand on its execution, not its outcome. .

A. Pain sensation behind the eyes. B. Pain during palpation. C. Pressure but no pain or tenderness. D. Tingling along the nose & eyes.

Correct Answer is C

Explanation

Choice A rationale

Pain sensation behind the eyes, particularly during palpation of the frontal or ethmoid sinuses, suggests inflammation or infection within these sinuses. Under normal conditions, healthy paranasal sinuses are air-filled cavities and should not elicit pain upon palpation.

Choice B rationale

Pain during palpation of any sinus area is indicative of sinusitis or inflammation. The presence of pain signifies pressure buildup, mucosal edema, or infection within the sinus cavities. Normal findings would not involve pain, but rather a sensation of mild pressure.

Choice C rationale

Normal findings during sinus palpation should elicit a sensation of pressure but no pain or tenderness. This indicates that the sinuses are air-filled, patent, and free from inflammation or congestion. The pressure is a result of the gentle digital compression over the bony structures.

Choice D rationale

Tingling along the nose and eyes is not a typical sensation associated with normal sinus palpation. This sensation might suggest neurological irritation, such as nerve compression or neuropathy, rather than a direct physiological response from the paranasal sinuses themselves.
