Labarotary - Lab Report Example In addition, infants have still to develop a urinary system that concentrates or dilutes urine in response to changes in extracellular fluid. Aside from that, they are still unable to effectively communicate their complaints, It is thus important that an outside monitoring of water loss and input be conducted to prevent complications such as dehydration or edema (Ambalavanan, 2010). Early determination of abnormal fluid levels gives room in early intervention and prevention of complications. Usually, one can predict predilection of infants to abnormal fluid levels by the maternal and newborn history. As well, measuring of fluid output through urine, stool, nasogastric, orogastric, and cerebrospinal fluid may be conducted (Ambalavanan, 2010). For this experiment, four nappies per pair were prepared. After previously weighing all four, two (labelled 1 and 2) were added with 15-50 ml water, while the remaining were added with 15-50 l of concentrated salt. Weight differences between unused and wet nappies were then determined and presented in the tables below. Table 1 summarizes the data collected by the pair of experimenters. As can be seen, the differences among the unused nappy weights were minimal, with the mean weight at 10.2 Â ± 0.2 grams. Any detected differences among wet nappies, must thus be because of the fluids they contain, and not of the material they are made of. Looking at the data of other pairs (table 2), specifically of group 2, it can be seen that equal volumes of water and salt solution does not cause any significant differences in the change of nappy weight. In support of this data, group 3 found that pouring a volume of the salt solution that was twice as much as the volume of water caused almost twice as high weight difference as that recorded in nappies added with the same amount of water. Data gathered by this pair of experimenters, as well as of other groups were not used in
