Nursing Elites

1. A scientist observes a new species of bird with uniquely shaped wings. They hypothesize that the wing shape allows for superior gliding ability. Which observation would most strongly support this hypothesis?

• A. The bird is found in mountainous regions.
• B. The bird has feathers with low friction.
• C. The bird can fly long distances without flapping.
• D. The bird's wing muscles are stronger than other birds.

Correct answer: C

Rationale: Direct observation of gliding ability directly tests the hypothesis about the wing shape's function. Other observations might be relevant but provide less direct evidence.

2. Which of the following is the best guarantee that the patient’s priority needs are met?

• A. Checking with the relative of the patient
• B. Preparing a nursing care plan in collaboration with the patient
• C. Consulting with the physician
• D. Coordinating with other members of the team

Correct answer: B

Rationale: Preparing a nursing care plan in collaboration with the patient is the best guarantee that the patient's priority needs are met because it involves actively involving the patient in their own care. This approach ensures that the patient's preferences, concerns, and priorities are taken into account when planning their care. Checking with the relative of the patient, consulting with the physician, and coordinating with other team members are important aspects of patient care, but collaborating with the patient directly ensures a patient-centered approach that addresses their individual needs and preferences.

3. The muscular tube that transports sperm from the testes to the urethra is called the:

• A. Epididymis
• B. Vas deferens
• C. Seminal vesicle
• D. Cowper's gland

Correct answer: B

Rationale: The correct answer is B: Vas deferens. The vas deferens is a muscular tube that carries sperm from the testes to the urethra. It is an essential part of the male reproductive system, allowing for the transport of sperm for ejaculation. The epididymis is a coiled tube where sperm mature and are stored, not where they are transported to the urethra. The seminal vesicle and Cowper's gland are accessory glands that contribute fluids to semen but are not part of the direct pathway for sperm transport.

4. Which force opposes the relative motion between surfaces in contact?

• A. Tension force
• B. Frictional force
• C. Gravitational force
• D. Magnetic force

Correct answer: b

Rationale: Friction is the force that opposes motion between surfaces in contact.

5. The pancreas releases a number of digestive enzymes into the small intestine. Which of the following enzymes is NOT produced by the pancreas?

• A. Trypsin (protein digestion)
• B. Amylase (carbohydrate digestion)
• C. Lipase (fat digestion)
• D. Lactase (sugar digestion)

Correct answer: B

Rationale: The correct answer is B: Amylase (carbohydrate digestion). The pancreas produces digestive enzymes that aid in breaking down food components. Trypsin is produced by the pancreas for protein digestion, lipase for fat digestion, and lactase is an enzyme produced in the small intestine for breaking down lactose (sugar). Amylase, on the other hand, is primarily produced in the salivary glands and the pancreas to break down carbohydrates into simple sugars. Therefore, amylase is not a pancreatic enzyme for digestion, making it the correct answer in this question.

6. Which of the following numbers is the greatest common factor (GCF) of 12 and 18?

• A. 2
• B. 3
• C. 6
• D. 9

Correct answer: C

Rationale: The GCF is the largest number that is a factor of both 12 and 18. We can factor each number to find common factors: 12 = 2 x 2 x 3 and 18 = 2 x 3 x 3. The greatest common factor that appears in both factorizations is 6 (2 x 3).
