A nurse is performing a neurological examination on a client as part of a complete physical assessment.
The nurse should identify that cranial nerve XI is intact when the client performs which of the following actions?

The correct answer is D. Urinary retention. Morphine is an opioid analgesic that can cause urinary retention by inhibiting bladder contractions and increasing sphincter tone. Urinary retention can lead to urinary tract infections, bladder distension, and renal impairment if not treated.

Choice A rationale:

Iron is essential for healthy blood, but it is not specifically associated with preventing neural tube defects. Iron supplementation is crucial during pregnancy to prevent iron-deficiency anemia.

Choice B rationale:

Calcium is essential for bone health, but it is not directly related to preventing neural tube defects. Adequate calcium intake is vital, especially during adolescence and pregnancy, to support bone development and maintenance.

Choice C rationale:

"Folate." This is the correct answer. Folate, also known as vitamin B9, is crucial for preventing neural tube defects. Adequate folate intake, especially before and during early pregnancy, can significantly reduce the risk of neural tube defects in newborns. The normal recommended dietary allowance (RDA) for folate is 400 micrograms per day for adults.

Choice D rationale:

Zinc is a mineral important for immune function and wound healing but is not specifically associated with preventing neural tube defects. Adequate zinc intake is essential for overall health, but it is not a primary nutrient targeted for neural tube defect prevention.
