Nursing Elites

1. Which type of epithelial tissue lines the inner lining of your intestines, responsible for absorption?

• A. Stratified squamous
• B. Simple columnar
• C. Stratified cuboidal
• D. Transitional epithelium

Correct answer: B

Rationale: The correct answer is simple columnar epithelium. This type of epithelial tissue is well-suited for absorption and secretion due to its tall, column-like shape and the presence of microvilli on its surface, which increase the surface area for absorption in organs like the intestines. Simple columnar epithelium is the ideal choice for the inner lining of the intestines as it allows for efficient nutrient absorption. Stratified squamous epithelium is typically found in areas subjected to abrasion, like the skin, and not suited for absorption. Stratified cuboidal epithelium is rare and found in specific gland ducts, not in the intestines. Transitional epithelium is specialized for stretching and is primarily found in the urinary system, not involved in absorption processes in the intestines.

2. What do hair follicles house in the skin?

• A. Blood vessels (Blood vessels are not housed within hair follicles)
• B. Nerve endings (Nerve endings are present but not housed within hair follicles)
• C. Hair shafts and hair roots
• D. Sebaceous glands (These glands are often attached to hair follicles)

Correct answer: C

Rationale: Hair follicles are structures in the skin that contain the hair shaft (the visible part of the hair) and the hair root (the part of the hair beneath the skin). The hair shaft is the portion of the hair that is visible above the skin, while the hair root is the part that extends below the surface into the follicle. Therefore, the correct answer is that hair follicles house the hair shafts and hair roots. Choices A, B, and D are incorrect because blood vessels are not housed within hair follicles, nerve endings are present but not housed within hair follicles, and sebaceous glands are often attached to hair follicles but not housed within them.

3. I truly believe that one cup of coffee a day is neither too much nor too little caffeine for me, but exactly the right amount. Which of the following words is misspelled in the sentence above?

• A. caffeine
• B. truly
• C. neither
• D. exactly

Correct answer: A

Rationale: The correct answer is A: 'caffeine.' The word 'caffeine' is spelled with only one 'e' after the 'f,' not 'caffiene.' 'Truly,' 'neither,' and 'exactly' are all spelled correctly in the sentence provided.

4. Which metric prefix represents 10^-2?

• A. centi
• B. milli
• C. nano
• D. deci

Correct answer: A

Rationale: The metric prefix 'centi-' signifies 10^-2, denoting one-hundredth of a unit. For instance, 1 centimeter equals 0.01 of the base unit. Choice B, 'milli,' represents 10^-3, 'nano' in Choice C represents 10^-9, and 'deci' in Choice D stands for 10^-1. Therefore, the correct answer is 'centi.'

5. In which of the following situations would you use formal language?

• A. Texting a friend
• B. A family reunion
• C. Skyping your grandparents
• D. At a Parent-Teacher meeting

Correct answer: D

Rationale: The correct answer is D: At a Parent-Teacher meeting. A Parent-Teacher meeting is a formal setting where professional communication is expected. Using formal language in this context shows respect and professionalism. Choices A, B, and C involve informal or casual situations where using formal language may not be necessary or appropriate. Texting a friend, attending a family reunion, or Skyping with grandparents are typically more informal interactions where a more relaxed communication style is acceptable.
