Answer:

The correct answer is: place the pulse oximeter in the baby's toe.

Explanation:

  • A pulse oximeter is a non-invasive medical device.
  • It is used to determine the concentration of oxygen-linked haemoglobin flowing in through the peripheral arterial blood.
  • It is generally used in those parts of the body where the skin is thin, like the finger tip of hand, toe tip or the ear lobe.
  • The difference in the absorbance of infrared light by the haemoglobin molecules linked to oxygen and the haemoglobin molecules not linked to oxygen is used to determine the concentration of oxygen in the peripheral arterial blood.
  • As the child has a difficulty in breathing so, it is obvious the amount of oxygen that all its body cells receive is far less than the amount of oxygen needed by them.

Answer:

B. "Whispered pectoriloquy" - "speaking from the chest"; used as a means of finding masses in the lung. The whispered word is audible in areas where fluid or a mass is present

Explanation:

Auscultation in medicine, is the action of listening to sounds from the heart, lungs, or other organs, usually using a stethoscope, in order to perform medical diagnosis.

Auscultation is performed for the purposes of examining the circulatory and respiratory systems, as well as the alimentary canal. The procedure is best performed in a quiet examination room. A stethoscope is used to magnify internal sounds. Small changes in breath sounds are carefully observed in order to make a diagnosis.

Whispered pectoriloquy is used to detect vocal resonance. It is  used as a means of finding masses (consolidations e.g. pus) in the lung and is performed by having the patient quietly whisper a word. If fluid or a mass is present, words that are whispered may be heard clearly.

Sister chromatids present during mitosis are
Ede4ka [16]

Answer:

The correct answer is e. All of the above.

Explanation:

Sister chromatids are made during the synthesis phase of the cell cycle. In the synthesis phase, the homologous chromosomes get replicated and sister chromatids are produced so they are produced by duplication of chromosomes.  

As sister chromatids are produced by replication, therefore, they are identical copies of parent chromosomes. These sister chromatids are joined to each other at centromere. They get separated during the anaphase of mitosis and moves to the opposite pole.

Therefore the right answer is e.
