Nursing Elites

1. What is the function of the Vas Deferens?

• A. Produces fluid to increase sperm mobility
• B. Site where the egg matures
• C. Helps control urine flow
• D. Connects each testis to the urethra

Correct answer: D

Rationale: The vas deferens is a duct that connects each testis to the urethra, allowing the transport of sperm. Choice A is incorrect because the vas deferens does not produce fluid to increase sperm mobility. Choice B is incorrect as the vas deferens is not a site for egg maturation. Choice C is incorrect as the vas deferens does not help control urine flow, its primary role is in the transport of sperm.

2. Which bone is the longest in the human body?

• A. Femur (Thigh bone)
• B. Humerus (Upper arm bone)
• C. Tibia (Shin bone)
• D. Scapula (Shoulder blade)

Correct answer: A

Rationale: The correct answer is the femur (thigh bone) as it is the longest bone in the human body, extending from the hip to the knee. It plays a vital role in supporting the body's weight and enabling movement. The humerus is located in the upper arm and is not as long as the femur. The tibia is the shin bone and is shorter than the femur. The scapula is the shoulder blade and is not the longest bone in the body, making it an incorrect choice.

3. As a nursing student triaging a patient, which of the following is an example of quantitative data you can gather?

• A. The patient says he feels pain.
• B. The patient says he has stabbing pain.
• C. The patient's temperature is 101.7°F.
• D. The patient reports that he had a fever yesterday.

Correct answer: C

Rationale: The corrected choice C, 'The patient's temperature is 101.7°F,' is an example of quantitative data because it provides a specific numerical value that can be measured. Quantitative data involves measurable and numerical information, making it crucial for assessing a patient's condition objectively. Choices A and B are subjective statements based on the patient's perception of pain and its description, which are qualitative data and may vary between individuals. Choice D provides historical information about a fever, which is not a current measurable value and does not constitute quantitative data for immediate assessment.

4. What is a gene, and what is the relationship between genes, genotype, and phenotype?

• A. A gene is a sequence of amino acids; genes make up proteins; genotype determines phenotype
• B. A gene is a portion of DNA; genes determine traits; genotype is the genetic makeup; phenotype is the physical manifestation
• C. A gene is a protein; proteins determine traits; genotype is the set of all genes
• D. A gene is a lipid; lipids determine traits; phenotype is the physical manifestation

Correct answer: B

Rationale: A gene is a portion of DNA that contains the instructions for a specific trait. Genotype refers to the genetic makeup of an organism, encompassing all its genes. Phenotype, on the other hand, is the observable physical manifestation resulting from the interaction between an organism's genotype and environmental factors. Choice A is incorrect because genes do not consist of amino acids directly; they are sequences of nucleotides. Choice C is incorrect as genes do not determine traits directly but provide the instructions for proteins that may influence traits. Choice D is incorrect as genes are not lipids, and lipids do not determine traits; they are a type of biomolecule with different functions.

5. Which of the following substances has an acidic pH?

• A. Lemon juice
• B. Blood
• C. Urine
• D. Salt water

Correct answer: A

Rationale: The correct answer is A, Lemon juice, which has an acidic pH typically around 2 due to its citric acid content. Blood, urine, and salt water are not typically acidic in nature. Blood has a slightly basic pH, urine can vary but is usually slightly acidic to neutral, and salt water is neutral to slightly alkaline. Lemon juice is a commonly known acidic substance, often used in cooking and cleaning due to its acidic properties.
