Nursing Elites

1. The RV was a great purchase for our family and brought us all closer together. Which of the following transitional phrases would improve this sentence?

• A. NO CHANGE
• B. Not surprisingly, the RV
• C. Furthermore, the RV
• D. As it turns out, the RV

Correct answer: D

Rationale: The transitional phrase 'As it turns out' adds a reflective tone that matches the surprise at how well the RV worked for the family. Choice A ('NO CHANGE') does not introduce any new information or transition. Choice B ('Not surprisingly, the RV') contradicts the surprise factor mentioned in the sentence. Choice C ('Furthermore, the RV') does not provide a suitable transition given the context of the sentence.

2. Which of the following epithelial tissues lines the stratified squamous epithelium of the esophagus, providing a protective barrier against abrasion from food passage?

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

Correct answer: B

Rationale: The correct answer is stratified squamous epithelium. This type of epithelium is found in areas subjected to mechanical and chemical stresses, such as the lining of the esophagus. The multiple layers of cells provide protection against abrasion from the passage of food. Simple squamous epithelium (choice A) is a single layer of flat cells and is not well-suited for protection against abrasion as it lacks the multiple layers. Simple cuboidal epithelium (choice C) is found in areas where secretion and absorption occur, such as kidney tubules, and is not typically found in the esophagus where protection against abrasion is necessary. Stratified cuboidal epithelium (choice D) is rare in the body and is not a characteristic tissue type of the esophagus, which requires stratified squamous epithelium for its protective function.

3. What is the role of the kidneys in the body?

• A. To regulate body temperature
• B. To filter waste from the blood
• C. To produce hormones
• D. To transport oxygen

Correct answer: B

Rationale: The correct answer is B: To filter waste from the blood. The kidneys play a crucial role in filtering waste products and excess substances from the blood to form urine, which helps maintain fluid balance and eliminate toxins from the body. Choice A is incorrect because regulating body temperature is primarily controlled by the skin and other mechanisms. Choice C is incorrect as hormone production is mainly attributed to other organs like the endocrine glands. Choice D is incorrect as the transportation of oxygen is primarily facilitated by the lungs and circulatory system, not the kidneys.

4. How many neurons typically comprise a sensory pathway?

• A. 1
• B. 2
• C. 3
• D. 4

Correct answer: C

Rationale: A sensory pathway generally consists of three neurons: a first-order neuron, a second-order neuron, and a third-order neuron. The first-order neuron carries sensory information from the periphery to the spinal cord or brainstem. The second-order neuron then transmits this information to the thalamus or cerebellum. Finally, the third-order neuron projects the sensory input to the cerebral cortex for processing and perception. Therefore, the correct answer is 3 (C). Choices A, B, and D are incorrect as they do not align with the typical structure of a sensory pathway involving three neurons.

5. Which of the following would be a useful source of information to determine the validity of the argument presented in this passage?

• A. A survey of high school students' foreign language preferences
• B. A comparison of the correlation between learning a second language at home and subsequent job placement rates
• C. A survey that asks parents about the foreign language they want their children to study in high school
• D. A comparison of the correlation between high school students' study of a foreign language and subsequent college acceptance rates

Correct answer: D

Rationale: Choice D is the correct answer as it can provide evidence to support the claim made in the passage that high school graduates who studied a foreign language are more likely to be accepted to college. This choice aligns with the argument presented in the passage, making it a useful source. Choices A and C focus on opinions rather than concrete evidence of the impact of studying a foreign language on future success. Choice B is not directly relevant as it talks about learning a second language at home, while the passage specifically discusses the importance of studying a foreign language in high school.
