Question

You are starring in a reality TV show, "Competitors", and are trapped on a deserted island. There was a nasty hurricane that wiped out all communication with the main land and you haven't been able to contact anyone on a cell phone, internet or radio. One of the "Competitors" is injured, vomiting profusely and will require i.v. infusions before the end of the day or he will die. The producers left plenty of 1-liter bags of sterile water, along with a number of chemicals in a lab before they abandoned you. To make an i.v. for the ill "Competitors" you decide to make a solution of 145mM NaCl/5nM KCL in 5% dextrose in a 1Liter bag of sterile water. The molecular weight of NaCl is 58.4, KCl is 74.5, and dextrose is 180. To make the solution you weigh out which of the following mixtures? 5.8g NaCl, 3.7g KCl, 5g dextrose 8.5g NaCl, 0.37g KCl, 50g dextrose 48g NaCl, 37g KCl, 50g dextrose 58.4g NaCl, 74.5g KCl, 5g dextrose 90g NaCl, 3.7g KCl, 5g dextrose You are starring in a reality TV show, "Competitors", and are trapped on a deserted island.

The molecular weight of NaCl is 58.4, KCl is 74.5, and dextrose is 180. In the end you expect the cells to: Remain the same Shrink Swell All of the above can happen. It depends on where the dextrose is at the time you are measuring Only A or B The goal of a PAP test is to look for dyplasia in the cervical cells of a woman. Which of the following cause dysplasia in cervical cells? Human Papillomavirus Measles Sexual intercourse A and C All of the above

Explanation / Answer

19.

We need to prepare 145mM NaCl, 5 mM KCl in 5 % dextrose in 1 L water.

Molecular weight of NaCl is 58.4, KCl is 74.5 and dextrose is 180.

To prepare 1 M solution if any substance we must dissolve its weights in molecular weight in gram in 1 L water.

For NaCl we need to dissolve 58.4 g NaCl in 1 L water to make 1 M NaCl solution and so on.

To make 145 mM of NaCl solution = 58.4 * 0.145 = 8.468 g = 8.5 g NaCl

To make 5 mM of KCl solution = 74.5 * 0.005 = 0.3725 g = 0.37 g KCl

To make 5% dextrose solution we need to take 5% of total waters weight.

1L water = 1kg water = 1000 g water.

5% of 1000 g = 50 g dextrose

(b) option is right.

20.

Saline solution is classic example of hypertonic solution.

I.V. solutions should have same osmolarity as cell, then it can transfer the solute freely.

Therefore, solution is Isoosmotic/hypertonic.

Option d

21.

Cell size will remain same. As only solute and not solvent will pass through cell membrane.

Option a

22.

Human Papillomavirus (HPV) is the common reason for cervical dysplasia.

Sexual intercourse with infected person can also result in cervical dysplasia, otherwise it is not a main cause.

Option a
