A lot of these words are derived from the Greek or Latin roots that mean what the word is used to mean in English. It's helpful to look up the etymology or understand what these roots mean because they come up all the time and in different combinations. This way you can look at a word you've never seen before and know what it means by breaking it down into its component parts.
1. Surgical puncture to remove fluid = centesis
2. Inflammation = itis
3. Abnormal hardening = sclerosis
4. Surgical removal = ectomy
5. Vomit = emesis
6. Infection = sepsis
7. Involuntary contraction = spasm
8. Surgical opening = stomy
9. Specialist in = ologist
10. Process of recording = graphy
11. Instrument that records = graph
12. Oxygen = oxia
13. Seizure attack = ictal
14. Paralysis = plegia
15. Surgical repair = plasty
16. Disease = pathy
17. Study of = logy
18. Tumor = oma
19. Enlargement = megaly
20. Breathing = pnea
21. Malignant tumor = sarcoma
22. Narrowing = stenosis
23. Swallowing or eating = phagia
Rhinoplasty = surgical repair of the nose
Ateriosclerosis = abnormal hardening of the arteries
Neuropathy = disease of the nervous system
Postictal = after a seizure attack
Answer: The next most appropriate step would be a LUMBAR PUNCTURE.
Explanation:
A LUMBAR PUNCTURE is a medical procedure that is usually carried out by a trained health personnel. It is a procedure that is carried out in the lumbar region of the spinal cord to access and obtain the cerebrospinal fluid which is used for further diagnosis of an underlying disease or illness.
A LUMBAR PUNCTURE is often adviced when the symptoms of a disease is related to the central nervous system. From the symptoms observed from the 19-year-old woman at the emergency department which includes:
--> generalized headache which is increasing in intensity,
--> blurred vision,
--> intermittent diplopia,
--> vague dizziness.
--> bilateral papilledema and
--> normal MRI of the brain.
Since the MRI of the brain is normal, the most appropriate step to be taken by the health care provider is a lumbar puncture which enables a direct access to the cerebrospinal fluid. This would help to rule out an elevated intracranial pressure which may be the cause of the generalized headache which is increasing in intensity.
Answer:
Deoxygenated blood enters the right atrium from the superior and inferior vena cava > The blood flows through the tricuspid valve into the right ventricle >From the right ventricle, the blood flows through the pulmonary valve into the pulmonary artery > The right and left pulmonary arteries carry deoxygenated blood to the right and left lungs for gas exchange > The blood releases carbon dioxide as waste and picks up a fresh supply of oxygen > The oxygenated blood flows through the pulmonary veins from the lungs into the left atrium > From the left atrium, the blood flows through the bicuspid, or mitral valve into the left ventricle > Left ventricular contraction forces blood through the aortic valve into the aorta for distribution to the systemic circulation
Explanation:
The tough, thin outer membrane covering the bones is called the periosteum.
