Answer to Question 1

Correct Answer: 4

Capillary blood collection is safe and effective for testing glucose and hematocrit, and may be used for blood specimens on infants. Arterial blood gases require artery puncture, and cannot be performed on a capillary specimen; it is possible to perform a capillary blood gas, which is less effective than an arterial sample but is less invasive.

Answer to Question 2

Correct Answer: 2

Midstream urine specimens are collected to reduce contamination of the specimen so it can be sent for culture and sensitivity. There would be no need for a 24-hour urine specimen, which is generally collected to measure the amount of an agent excreted in the course of the day, such as creatine or sodium. A routine urine specimen does not try to limit bacteria or contaminants, and is often used to test for sugar, protein, and specific gravity. A timed urine specimen is used when a small amount of a substance is being measured, such as the presence of human chorionic gonadotropin (HCG), which confirms pregnancy.
