NNAAP District of Columbia Nurse Aides - Blogs Sample Questions

Giving nutrition through a catheter inserted into a vein is called:

Correct Answer:
parenteral nutrition


the correct answer to the question "giving nutrition through a catheter inserted into a vein is called:" is "parenteral nutrition." parenteral nutrition is a medical method used to nourish patients who are unable to get their nutrients through eating. this could be due to an inability to swallow, digest, absorb, or maintain adequate oral intake.

in parenteral nutrition, nutrients are delivered directly into the bloodstream through a catheter, which is most commonly placed in a large vein in the chest or the arm. this bypasses the gastrointestinal (gi) tract entirely, which is why it's termed "parenteral," meaning outside of the intestines. the nutrients provided include a balance of carbohydrates, proteins, fats, vitamins, and minerals, necessary for energy and the normal functioning of the body.

this method is also referred to as total parenteral nutrition (tpn) or hyperalimentation, especially when it meets the complete nutritional needs of the patient. tpn is typically employed when a patient's digestive system is non-functional due to complications such as surgery, trauma, or severe illness.

the term "subclavian" in the context of parenteral nutrition refers to the subclavian vein, which is a common site for the catheter placement because of its large size and accessibility. however, the placement of the catheter does not change the type of nutrition being administered; it remains parenteral nutrition irrespective of the site used for the catheter.

"tube feeding," another option mentioned, is different from parenteral nutrition. in tube feeding, a special liquid food mixture is given through a tube directly into the stomach or small intestine. this method is used when the patient's gi tract is working but they are unable to eat by mouth.

lastly, "iv therapy" is a broader term that involves the administration of substances directly into a vein, which can include medications, fluids, or electrolytes, and not necessarily nutritional solutions. it is important not to confuse general iv therapy with the more specific and nutritionally complete process of tpn or parenteral nutrition.

Sometimes when a patient has a weakness on one side of the body he or she forgets that that side exists and so the patient will not dress, bathe or otherwise care for that side. This is called:

Correct Answer:
unilateral neglect
unilateral neglect, also known as hemispatial neglect or hemineglect, is a neuropsychological condition often observed in patients who have experienced brain damage, particularly to the right hemisphere. this condition manifests as an inability to pay attention to and process stimuli on one side of the body or space. commonly, this neglect is towards the left side when the right hemisphere is damaged, though the reverse can occur with damage to the left hemisphere.

the typical symptoms of unilateral neglect include the patient not acknowledging the existence of the affected side of the body. for instance, a person with this condition might only eat food from the right side of their plate, or only dress the right side of their body, completely ignoring the left side. they may also fail to shave or apply makeup to the neglected side of their face. importantly, this neglect is not due to a sensory loss or motor impairment; instead, it is a failure in attention and awareness.

the underlying cause of unilateral neglect is complex and not entirely understood, but it is primarily associated with cerebral lesions following a stroke or other brain injuries, particularly in the parietal lobes, which play a critical role in spatial awareness and attention. neuroimaging studies show that damage to the networks involving the parietal, frontal, and occipital lobes can contribute to this condition.

a crucial aspect of dealing with unilateral neglect is that simply reminding the patient of their neglected side is typically ineffective. care strategies often involve physical therapy, occupational therapy, and sometimes the use of specialized techniques to train the brain in awareness and compensation. techniques might include visual scanning training, where patients are taught to consciously attend to the neglected side, or the use of prisms and other visual aids to help reorient their perception of space.

in summary, unilateral neglect is a significant and often challenging consequence of brain injury, primarily affecting the patient's ability to perceive and interact with one side of the body or space. effective management requires a comprehensive approach tailored to the specific needs and capabilities of each patient, focusing on rehabilitation and adaptive strategies to improve quality of life.
