Anatomy
1. Bile, a yellowish-green fluid, is stored in the gallbladder and released into the small intestine during digestion. What is the primary function of bile in digestion?
- A. Break down carbohydrates
- B. Break down proteins
- C. Emulsify fats
- D. Neutralize stomach acid
Correct answer: C
Rationale: The primary function of bile in digestion is to emulsify fats. Bile contains bile salts that help break down large fat globules into smaller droplets, which increases the surface area for enzymes to work on and aids in the absorption of fats in the small intestine. This process is essential for the digestion and absorption of dietary fats. Bile does not directly break down carbohydrates or proteins, and it is not involved in neutralizing stomach acid, making option C the correct answer.
2. When light reflects from a surface, what determines the angle of reflection?
- A. The material of the surface
- B. The wavelength of the light
- C. The angle of incidence
- D. The intensity of the light
Correct answer: C
Rationale: The angle of reflection is always equal to the angle of incidence according to the law of reflection, regardless of the material, wavelength, or intensity.
3. One staff suggests that they review the pattern of nursing care that they are using, which is
- A. job description
- B. system used to deliver care
- C. manual of procedure
- D. rules to be followed
Correct answer: B
Rationale: The correct answer is B: 'system used to deliver care.' When a staff member suggests reviewing the pattern of nursing care being used, they are referring to the overall system or method in place for delivering care to patients. This includes the processes, protocols, and techniques used to provide nursing care. It goes beyond just following a job description, manual of procedure, or rules. By evaluating and potentially revising the system used to deliver care, staff can ensure that best practices are in place to provide high-quality and effective care to patients.
4. The main function of the nephrons is to:
- A. Store urine
- B. Filter blood and remove waste products
- C. Produce hormones
- D. Control blood pressure
Correct answer: B
Rationale: The correct answer is B: 'Filter blood and remove waste products.' Nephrons are the functional units of the kidneys responsible for filtering blood to remove waste products, excess ions, and water, while reabsorbing essential substances like glucose and amino acids. This process forms urine, which is stored in the bladder before being excreted. Options A, C, and D are incorrect because nephrons do not store urine, produce hormones, or directly control blood pressure; although the kidneys do play a role in long-term blood pressure regulation through mechanisms like the renin-angiotensin-aldosterone system.
5. Which of the following is an example of a secondary alcohol?
- A. Methanol
- B. Ethanol
- C. Isopropanol
- D. Butanol
Correct answer: C
Rationale: Isopropanol is an example of a secondary alcohol, as the hydroxyl group is attached to a carbon atom that is bonded to two other carbon atoms. The other choices are primary alcohols.
6. Which word in the sentence "The quick brown fox jumps over the lazy dog" demonstrates alliteration?
- A. quick
- B. brown
- C. fox
- D. jumps
Correct answer: A
Rationale: Alliteration is the repetition of the first consonant sound of words close together. In this case, "quick" and "brown" both start with the "k" sound.
