Answer 1

1. (c) phenylketonuria :- it is an inborn metabolism error in which there is decreased metabolism of amino acid phenylalanine.
2. (c) Glass slide :- In malaria test, malarial parasite is identified by taking a drop of patient's blood and spreading out as blood smear on glass slide and then observing under the microscope.
3. (b) Coagulation :- For coagulation studies plasma specimen cannot be collected by capillary puncture, due to contamination with interstitial fluid which promote clotting.
4. (a) Arterial blood:- capillary blood is a mixture of arterial, venous, capillary, intestitial and cellular fluids. Due to this mixture, capillary blood resembles more to arterial blood
5. (a) Calcium: Analytes such as calcium, potassium and total protein are normally lower in capillary specimen than in venous.
6. (b) removing larger quantities of blood can lead to anemia.
7. (c) purple top
8. (b) Distal segment of the middle finger
9. (c) on the big toe side of the bottom of the heel
10. (b) bone injury
11. (b) increase blood flow:-
12. (b) below 2.4 mm in depth, pain fibres increase in bulk below the capillary bed, so deeper punctures are more painful.
13. (d) all of the above
14. (a) to minimize the fluid contamination
15. (d) All of the above, povidone iodine contamination of skin puncture affects the results of BURP test
