A nurse is teaching a client who is trying to conceive.
Which of the following should the nurse instruct the client to increase in her diet to prevent a neural tube defect?

Choice A rationale:
Contractures are a risk for this client due to the lack of movement and constant positioning on one side. Contractures occur when the muscles, tendons, or ligaments shorten and tighten, limiting range of motion and flexibility. This can be a result of prolonged immobility or lack of use of the muscles.
Choice B rationale:
Calcium resorption is not a risk for this client. Calcium resorption refers to the process where bone tissue is broken down and calcium is released into the bloodstream. This process is not directly related to immobility or multiple sclerosis.
Choice C rationale:
Hypocalcemia, or low calcium levels in the blood, is also not a direct risk for this client. While immobility can lead to bone loss over time, it does not directly cause hypocalcemia.
Choice D rationale:
Diarrhea is not a risk for this client based on the information provided. Diarrhea can be a symptom of many conditions but there is no indication in the scenario that this client is at risk.
Choice E rationale:
Urinary stasis is a risk for this client due to their immobility. When a person is immobile, urine can pool in the bladder, creating an environment where bacteria can grow, potentially leading to urinary tract infections.

The correct answer is Choice B: Assign the child to a negative air pressure room.

Choice A rationale: Assessing the child for Koplik spots is not appropriate in this situation because Koplik spots are associated with measles, not varicella. Koplik spots are small, white, irregular lesions that appear on the buccal mucosa during the prodromal phase of measles. They do not present in cases of varicella, which is characterized by a pruritic, vesicular rash.

Choice B rationale: Assigning the child to a negative air pressure room is the most suitable action because varicella is highly contagious and can be transmitted through airborne particles. A negative air pressure room helps to contain these particles and minimize the risk of infection transmission to other patients, healthcare workers, and visitors. Airborne precautions are the recommended infection control measures for managing varicella cases in healthcare settings.

Choice C rationale: Utilizing droplet precautions alone is insufficient for managing varicella because the virus can also be spread through airborne particles. While droplet precautions may be a component of the overall infection control strategy, they are inadequate without the additional implementation of airborne precautions, such as a negative air pressure room.

Choice D rationale: Administering aspirin to a child with a viral illness is generally contraindicated due to the potential risk of Reye's syndrome, a rare but severe condition characterized by liver failure and encephalopathy. It is essential to follow appropriate guidelines for managing fever and discomfort in pediatric patients with varicella, which typically involve using acetaminophen or ibuprofen instead of aspirin.
