A nurse is instructing a female client on obtaining a midstream urine specimen. Which of the following statements by the client indicates an understanding of the teaching?

Choice A reason:

Babinski's sign is a neurological reflex that's tested by stroking the sole of the foot. A positive Babinski's sign, which is normal in infants but abnormal in adults, is indicated by dorsiflexion of the great toe (the toe points up) while the other toes fan out. This reflex suggests dysfunction of the corticospinal tract, which may be due to various neurological conditions. In the context of a stuporous patient with an unrepaired femur fracture, a positive Babinski's sign could indicate an acute neurological change possibly related to the injury or a secondary complication such as a fat embolism syndrome, which can occur after fractures and may affect the brain.

Choice B reason:

Pronation of the arms is not associated with Babinski's sign. Pronation is a rotational movement where the hand and upper arm are turned inwards. While arm movements are part of the neurological examination, they do not constitute a response to the plantar reflex test used to elicit Babinski's sign.

Choice C reason:

Pinpoint pupils may indicate opioid overdose or damage to the pons due to various causes, but they are not a component of Babinski's sign. Pupil size and reaction to light are important in neurological assessments, but they are separate from the reflexes tested by the Babinski sign.

Choice D reason:

Jerking contractions of the head and neck are not related to Babinski's sign. These could be indicative of seizure activity or other neurological disorders but are not a response to the plantar reflex test.

Choice A reason:
Hemodialysis does not typically result in a significant decrease in RBC count. While there can be a minimal loss of red blood cells during the process, it is not the primary focus of the treatment. The main purpose of hemodialysis is to remove waste products and excess fluid from the blood when the kidneys are not functioning properly.

Choice B reason:
Calcium levels may vary during hemodialysis, and the treatment can be adjusted to prevent significant changes in calcium levels. Hemodialysis can remove some calcium from the blood, but it is usually not the most affected value, and calcium can be added to the dialysate solution if necessary.

Choice C reason:
Potassium is one of the primary electrolytes removed during hemodialysis. High levels of potassium, which can be life-threatening, are commonly seen in clients with renal failure. Hemodialysis effectively reduces high potassium levels, which is crucial for preventing complications such as cardiac arrhythmias.

Choice D reason:
Protein levels are not directly targeted by hemodialysis, and significant protein loss is not a usual outcome of the treatment. The dialysis membrane is designed to allow smaller molecules like urea and potassium to pass through while retaining larger molecules like proteins.
