1. What is the scientific term for inflammation of the bronchi, often associated with a cough and mucus production?
- A. Pneumonia
- B. Bronchitis
- C. Emphysema
- D. Pleurisy
Correct answer: B
Rationale: The correct answer is B: Bronchitis. Bronchitis is the scientific term for inflammation of the bronchi, which are the air passages in the lungs. This condition is often characterized by a cough, mucus production, and difficulty breathing. Pneumonia (A) is an infection that causes inflammation in the air sacs in the lungs, not the bronchi. Emphysema (C) is a chronic lung condition that results in the damage of the air sacs in the lungs, leading to difficulty breathing. Pleurisy (D) is inflammation of the pleura, the lining around the lungs, and is not directly related to inflammation of the bronchi. Therefore, option B is the correct answer in this case.
2. Micturition involves a combination of:
- A. Gravity alone
- B. Voluntary muscle contractions only
- C. Involuntary muscle contractions only
- D. Both voluntary and involuntary muscle contractions
Correct answer: D
Rationale: The correct answer is D: 'Both voluntary and involuntary muscle contractions.' Micturition, also known as urination, is a complex process involving both voluntary and involuntary muscle contractions. The voluntary muscle contractions allow us to control when we urinate, while the involuntary muscle contractions help to expel urine from the bladder. Gravity alone (option A) is not sufficient for micturition, as muscle contractions are necessary to empty the bladder. Similarly, relying on voluntary muscle contractions only (option B) would not be effective, as involuntary contractions are also needed to fully empty the bladder. Lastly, option C stating 'Involuntary muscle contractions only' is incorrect because voluntary muscle contractions play a crucial role in micturition. Therefore, option D is the most comprehensive and accurate choice.
3. What is the primary function of ribosomes in the cell?
- A. To synthesize lipids and other cellular components
- B. To package and transport proteins
- C. To break down macromolecules
- D. To translate mRNA into proteins
Correct answer: D
Rationale: Rationale: Ribosomes are cellular organelles responsible for protein synthesis. They read the genetic information encoded in messenger RNA (mRNA) and use this information to assemble amino acids into a specific sequence, forming a protein. This process is known as translation and is essential for the production of proteins that carry out various functions in the cell. Options A, B, and C do not accurately describe the primary function of ribosomes in the cell.
4. She takes pride in saying that the hospital has a decentralized structure. Which of the
- A. Flat organization
- B. Participatory approach
- C. Shared governance
- D. Tall organization
Correct answer: B
Rationale: The correct answer is B: 'Participatory approach.' In a decentralized structure, decision-making authority is dispersed throughout the organization rather than being concentrated at the top. A participatory approach involves employees at all levels having a say in decisions that affect their work, fostering collaboration and empowerment. This contrasts with a tall organization, which has many layers of management and a more centralized decision-making process. While shared governance can involve decentralized decision-making, it specifically refers to a model where nurses and other healthcare professionals have a voice in shaping policies and practices within their organization, which is not necessarily the same as a decentralized structure.
5. What is the name of the muscular ring that controls the passage of food from the esophagus to the stomach?
- A. Pyloric sphincter
- B. Cardiac sphincter
- C. Ileocecal valve
- D. Sphincter of Oddi
Correct answer: B
Rationale: The correct answer is B: Cardiac sphincter. The cardiac sphincter, also known as the lower esophageal sphincter, is the muscular ring located at the junction between the esophagus and the stomach. It controls the passage of food from the esophagus into the stomach by opening and closing to prevent reflux of stomach contents back into the esophagus. The other options are incorrect: A) The pyloric sphincter is located at the junction between the stomach and the small intestine, controlling the passage of food from the stomach into the small intestine. C) The ileocecal valve is located between the small intestine and the large intestine. D) The Sphincter of Oddi is located in the duodenum and regulates the flow of bile and pancreatic juice into the small intestine. Therefore, the correct answer is B because it specifically relates to the passage of food from the esophagus to the stomach.
6. Which of the following is a property of amphiprotic substances?
- A. React with acids only
- B. React with bases only
- C. Can act as both acids and bases
- D. Are inert in chemical reactions
Correct answer: C
Rationale: Amphiprotic substances can donate or accept a proton, so they can act as both acids and bases. The other choices do not accurately describe amphiprotic substances.
