There are 2 types of parenteral nutrition, Total Parenteral Nutrition (TPN) and Peripheral Parenteral Nutrition (PPN). TPN must be administered using:
NGT
Orally
Central Line
Peripheral line
The Correct Answer is C
Choice A reason: NGT (nasogastric tube) is used for enteral feeding, not parenteral nutrition. Enteral feeding involves delivering nutrients directly to the stomach or small intestine, bypassing the need for eating. This method is suitable for patients who have a functioning digestive system but cannot eat orally. Parenteral nutrition, on the other hand, involves delivering nutrients directly into the bloodstream.
Choice B reason: Oral administration of nutrition involves consuming food or nutrients by mouth. This method is suitable for individuals who can eat and digest food normally. Parenteral nutrition bypasses the digestive system altogether and delivers nutrients directly into the bloodstream, making oral administration inappropriate for TPN.
Choice C reason: Central Line is the correct answer because Total Parenteral Nutrition (TPN) requires delivery of nutrients directly into a central vein, typically the superior vena cava. This is because TPN solutions are highly concentrated and can irritate smaller veins, leading to complications such as phlebitis. A central line allows for the safe administration of TPN, ensuring that the high osmolarity solution is rapidly diluted by the large volume of blood in the central veins.
Choice D reason: Peripheral line administration is used for Peripheral Parenteral Nutrition (PPN), not TPN. PPN can be delivered through a peripheral vein because it is less concentrated than TPN. Using a peripheral line for TPN is not appropriate due to the risk of complications from the high osmolarity of the TPN solution.

Correct Answer is C
Explanation
Choice A reason: Breastfed babies typically have unformed (rather than formed) stools that are yellow and seedy, not yellowish-brown. Formula-fed babies tend to have more formed stools that are light brown or tan in color. The stooling frequency is often higher in breastfed babies compared to formula-fed babies.
Choice B reason: This description is incorrect. Formula-fed babies typically have more formed stools that can range from light brown to tan, rather than yellow. Breastfed babies usually have yellow, unformed stools and tend to stool more frequently.
Choice C reason: Breastfed babies have soft, unformed, and yellow stools due to the easy digestibility of breast milk. Formula-fed babies tend to have less frequent stooling patterns and their stools are more formed and light brown in color. This difference is due to the different compositions of breast milk and formula.
Choice D reason: Breastfed babies do not usually have light brown stools; their stools are typically yellow and unformed. Formula-fed babies can have yellow stools in some cases, but more commonly, their stools are light brown or tan and more formed.
Correct Answer is C
Explanation
Choice A reason: Increasing red meat in the diet is not an appropriate treatment for hypovolemia due to hemorrhage. While red meat contains iron, which is important for blood production, it does not address the immediate need to replace lost blood volume.
Choice B reason: Infusing D5NS (5% Dextrose in Normal Saline) at 75 ml/hr for 10 hours may help replenish fluid volume, but it does not provide the necessary components to replace lost blood cells and clotting factors. This option is not sufficient for severe hemorrhage.
Choice C reason: Replacement of volume with blood products is the treatment of choice for hypovolemia due to hemorrhage. Blood transfusions provide the necessary red blood cells, plasma, and clotting factors to restore blood volume and improve oxygen delivery to organs. This is crucial in managing severe blood loss and preventing complications such as hypovolemic shock.
Choice D reason: Increasing H2O (water) intake to 400 ml/4 hr for 24 hours is not an appropriate treatment for hypovolemia due to hemorrhage. While hydration is important, it does not address the immediate need to replace lost blood volume and components.
