Nursing Metric Conversion

1. What is 0.5 L converted to mL?

Correct answer: A

Rationale: To convert liters to milliliters, you need to multiply by 1000 since 1 liter is equal to 1000 milliliters. Therefore, 0.5 liters multiplied by 1000 equals 500 milliliters. Choice A, 500 mL, is the correct answer. Choice B, 50 mL, is incorrect as it represents converting 0.05 liters to milliliters. Choice C, 5 mL, is incorrect as it represents converting 0.005 liters to milliliters. Choice D, 0.5 mL, is incorrect as it represents the original amount in milliliters, not the conversion of liters to milliliters.

2. Which part of the spinal cord is responsible for transmitting sensory information from the body to the brain?

Correct answer: A

Rationale: The correct answer is the dorsal root. The dorsal root of the spinal cord contains sensory nerve fibers that transmit sensory information from the body to the brain. This information includes touch, pain, temperature, and proprioception. The ventral root, on the other hand, contains motor nerve fibers responsible for carrying signals from the brain to the muscles and glands, controlling movement and glandular functions. Gray matter, consisting mainly of cell bodies, is involved in processing and integrating sensory and motor information within the spinal cord. White matter is primarily composed of myelinated axons that facilitate communication between different regions of the nervous system, allowing signals to travel efficiently within the spinal cord and between the brain and other parts of the body. Therefore, the dorsal root is specifically associated with transmitting sensory information, making it the correct answer in this context.

3. What are the small, finger-like projections in the small intestines called?

Correct answer: D

Rationale: The correct answer is D: Villi. Villi are small, finger-like projections in the small intestine that increase the surface area for absorption, aiding in the absorption of nutrients. Cilia (Choice A) are tiny hair-like structures found in various parts of the body but are not present in the small intestine. Rugae (Choice B) are folds in the mucosa of the stomach that allow for its expansion during digestion. The trachea (Choice C) is part of the respiratory system, responsible for carrying air to and from the lungs, and is not related to the small intestine.

4. Why is it essential to formulate a hypothesis before conducting an experiment?

Correct answer: B

Rationale: Formulating a hypothesis before conducting an experiment is crucial because it helps guide the investigation by suggesting what the investigator should be looking for. A hypothesis serves as a prediction or an educated guess about what might happen in the experiment, providing a clear direction for the research process. It allows the investigator to focus on specific variables and outcomes, making the experiment more organized and effective. Choice A is incorrect because the primary purpose of a hypothesis is not to boost an investigator's reputation but to guide the research. Choice C is incorrect as formulating a hypothesis is not primarily about impressing funders but about setting a clear direction for the study. Choice D is incorrect because the hypothesis is not meant to dictate which results to keep based on preconceived notions but to guide the investigation and allow for unbiased interpretation of results.

5. Which organ produces insulin and glucagon?

Correct answer: D

Rationale: The correct answer is D, Pancreas. The pancreas is the organ responsible for producing the hormones insulin and glucagon. Insulin functions to lower blood sugar levels by facilitating the uptake of glucose by cells for energy production. On the other hand, glucagon works to raise blood sugar levels by prompting the liver to release stored glucose into the bloodstream. The pancreas is a vital organ in the endocrine system, playing a crucial role in maintaining appropriate blood sugar levels in the body. Choices A, B, and C are incorrect as the salivary glands produce saliva, the liver is involved in various metabolic functions, and the gallbladder stores bile produced by the liver, but none of these organs produce insulin and glucagon.
