What is nondisjunction? ______________ When does it happen? _______________ What is the result? __________ Name some examples __
BARSIC [14]

Answer:

The process of reproduction is a pretty complex one, and there are several steps that are taken that, if taken wrong, can lead to abnormalities. The most important thing to know is that all humans have two sets of 23 chromosomes, one from each of their parents. The correct process of egg and sperm formation is meiosis, and it will ensure that from the originating cell, the gametes (or eggs) formed, will have the total amount of chromosomes needed.

During this process of meiosis, the chromosomes should be separated and evenly divided. But first, DNA replication must take place. This means that first two homologous chromosomes, and are created so that all new cells will have the same DNA information. This happens in Meiosis I, Anaphase I. On the second phase of meiosis, in its anaphase (meiosis II, anaphase II) a new division will happen, but this time, of sister chromatids. This separation process is called disjunction.

So, in answer to the question above, we have that:

1. Non-disjunction: is when the two pairs of homologous chromosomes (in meiosis I, anaphase I), or the two sister chromatids (in meiosis II, anaphase II), do not separate, or parts remain with the other.

2. This happens during two phases of Meiosis: Meiosis I, anaphase I and Meiosis II, anaphase II.

3. The result can be two cells with extra copies of chromosomes, and the other missing that extra pair of chromosomes and in the case of nondisjunction in anaphase II, the results can be: two normal haploid cells, and the other two will, one have an extra chromosome, and the other, be totally missing it.

4. Some examples of these situations, when female and male gametes unite to form a baby, would be: Trisomies (extra copies of chromosomes) and Monosomies (absent normal numbers of chromosomes).

Administer the prescribed enoxaparin (Lovenox).

  • The anticoagulant enoxaparin sodium is sold under brand names such as Lovenox. It is used to treat and prevent pulmonary embolism and deep vein thrombosis, especially during pregnancy and after some types of surgery.
  • Heart attacks and acute coronary syndromes are also treated. A prescription drug called Lovenox is used to treat and prevent signs and symptoms of chest pain and blood clots (deep vein thrombosis or DVT) (angina). Lovenox can be taken alone or with other medicines.
  • Lovenox belongs to a class of drugs known as cardiovascular and blood anticoagulants. Tell your doctor if you have side effects that bother you or that don't go away.

Therefore, enoxaparin must be injected in such cases.

the nurse is providing preoperative teaching for the patient who is to undergo a total laryngectomy. which nursing intervention
Citrus2011 [14]

Most important nursing intervention after laryngectomy is that after surgery, your voice may return to normal but you will sound hoarse.

Since the false cords are removed during a supraglottic partial laryngectomy, patients may recover from surgery with a normal or raspy voice. A total laryngectomy patient won't have a natural voice. A laryngo-fissure patient will have a normal voice. A hemilaryngectomy patient will have hoarse voice. Thus, the patient after a total laryngectomy will have a hoarse voice.

The larynx can be removed in whole or in part through a laryngectomy (voice box). It entails making an incision (cut) over the Adam's apple region on the outside of the neck. Partial laryngectomy: In order to treat some laryngeal malignancies, only a portion of the voice box needs to be removed.

The nurse is analyzing the arterial blood gas (agb) results of a client diagnosed with severe pneumonia. what abg results are mo
Leona [35]

ABG results that are most consistent with this diagnosis are:

- pH of the patient : 7.20

- PaCO_{2} of patient is low : 65 mm Hg

- HCO_{3} of patient : 26 mEq/L

<h3>What is ABG?</h3>
  • An arterial blood gas (ABG) test, which draws blood from an artery in your body, determines the levels of oxygen and carbon dioxide in your blood.
  • The pH balance, sometimes referred to as the acid-base balance, of your blood is also examined during the test.
  • The National Institute of Health lists the following as typical normal values: pH: 7.35-7.45.
  • Oxygen partial pressure (PaO_{2}) ranges from 75 to 100 mmHg. Carbon dioxide (PaCO_{2}) partial pressure ranges from 35 to 45 mmHg.
  • The blood gas test can reveal how efficiently your lungs can introduce oxygen into the blood and expel carbon dioxide.
