Answer: Option (A) is the correct answer.

Explanation:

A mixture is defined as the substance that contains two or more different number of substances which are physically mixed together.

For example, a mixture of mud and water can be separated through the process of filtration.

A pure substance is defined as the substance which contains either same or different type of atoms that are chemically combined to each other in a fixed ratio by mass.

For example, both Cl_{2} and MgSO_{4} are pure substances.

A pure substance can only be separated by chemical means.

Thus, we can conclude that one difference between mixtures and pure substances is that mixtures can be physically separated.

The patient is a 63-year-old gentleman diagnosed with rectal cancer, who had a resection of the cancer performed. he now present
Tpy6a [65]

The correct answer is CPT codes 36561, 77001-26.

The administration of a tunneled Port-A-Cath through the subclavian vein was done on a 63-year-old. It is essential to note that it is tunneled. The procedure was done under fluorescence guidance for placement of a central venous access instrument.  

The Port-A-Cath method is witnessed in the CPT index by looking for Central Venous Catheter Insertion/Placement/Tunneled/Centered with Port directs one to 36560, 36561, 36566. The code 36561 is the correct code. The guidelines for central venous access methods directs one to use 77001 for fluoroscopic guidance.  

This can be witnessed in the CPT index by looking for Venous/Fluoroscopy Access Device or Venous Access Device/Fluoroscopic guidance instructing one to add-on code 77001.

You have a large bottle of 2% saline solution in the lab (2% NaCl, which is sodium chloride). You need 5 ml of 0.1% saline for a
zvonat [6]

Answer:

volume of 2% saline (V₁) = 0.25ml

volume of water = 4.75ml

Explanation:

The requirement in the question is to obtain 0.1% of NaCl from 2% NaCl, and the process is dilution. The general dilution equation is guven by:

C₁V₁ = C₂V₂

where:

C₁ = initial concentration = 2%

V₁ = initial volume = ?

C₂ = final concentration = 0.1%

V₂ = final volume = 5ml

C₁V₁ = C₂V₂

calculating for V₁

∴ V₁ = (C₂V₂) ÷ C₁

= (0.1% × 5) ÷ 2%

V₁ = 0.25ml

Now, let us calculate the volume of water needed:

V₁ + Volume of water = V₂ (volume of 0.1% NaCl)

0.25 + volume of water = 5

volume of water = 5 - 0.25

volume of water = 4.75ml
