Nursing Elites

1. Through which part of the digestive system are nutrients absorbed into the bloodstream?

• A. Stomach
• B. Large intestine
• C. Small intestine
• D. Esophagus

Correct answer: C

Rationale: The small intestine is the primary site of nutrient absorption in the digestive system. It is where the majority of digestion and absorption of nutrients such as carbohydrates, proteins, and fats occurs. The inner lining of the small intestine is covered in tiny finger-like projections called villi, which increase the surface area available for absorption. Nutrients are absorbed through the walls of the small intestine and into the bloodstream to be transported to cells throughout the body. The stomach's main role is to break down food through the action of stomach acids and enzymes but does not absorb nutrients. The large intestine primarily absorbs water and electrolytes from the remaining indigestible food matter, and the esophagus is a muscular tube that transports food from the mouth to the stomach, without being involved in nutrient absorption.

2. Which detail from the passage best supports the conclusion that the little girl is no older than three years old?

• A. For lunch, she likes ham and cheese (torn into bites), yogurt, raisins, applesauce, peanut butter sandwiches in the fridge drawer, or any combo of these.
• B. It’s fine if you want to go somewhere, just leave us a note of where you are.
• C. As for nap, try after lunch. She may not sleep, but try anyway.
• D. Turn on music in her room, leave her in her crib with a dry diaper and bottle to try to sleep.

Correct answer: D

Rationale: The detail from choice D, 'Turn on music in her room, leave her in her crib with a dry diaper and bottle to try to sleep,' best supports the conclusion that the little girl is no older than three years old. This detail suggests that the child is still using a crib for sleeping, a common practice for infants and toddlers. Additionally, the mention of a bottle indicates that the child is likely young, as older children typically do not use bottles for sleep. Choices A, B, and C do not provide specific details related to the child's age like the mention of a crib and a bottle does in choice D.

3. Which part of the eye controls the amount of light that enters the eye?

• A. Cornea
• B. Iris
• C. Retina
• D. Lens

Correct answer: B

Rationale: The iris is the correct answer as it controls the amount of light that enters the eye by adjusting the size of the pupil. The cornea is responsible for focusing light onto the retina, the retina detects light at the back of the eye, and the lens helps in further focusing light onto the retina. The iris, through changing the size of the pupil, regulates the amount of light reaching the eye, making it the part that controls the entry of light.

4. What is the main function of the pancreas?

• A. To store food and break it down into smaller pieces
• B. To absorb nutrients into the bloodstream
• C. To produce enzymes that help digest food
• D. To regulate blood sugar levels

Correct answer: C

Rationale: The main function of the pancreas is to produce digestive enzymes that aid in breaking down carbohydrates, fats, and proteins in food. These enzymes are essential for the digestion and absorption of nutrients in the small intestine. While the pancreas also plays a role in regulating blood sugar levels by producing insulin and glucagon, its primary function is to produce enzymes for food digestion. Options A and B are incorrect as the pancreas is not involved in storing food or absorbing nutrients into the bloodstream.

5. Select the book title that does not contain a preposition.

• A. The Man in the Brown Suit
• B. The Secret of Chimneys
• C. Murder on the Orient Express
• D. And Then There Were None

Correct answer: D

Rationale: The correct answer is 'D' - 'And Then There Were None.' This title does not contain a preposition. Prepositions are words that show the relationship of a noun or pronoun to another word in the sentence. In this title, 'And,' 'Then,' 'There,' and 'None' are not prepositions; they are conjunctions and pronouns. Choices A, B, and C all contain prepositions: 'in,' 'of,' and 'on,' respectively. Therefore, they are incorrect answers for this question.
