Biology
1. What enzyme plays a key role in breaking down carbohydrates in the small intestine?
- A. Pepsin
- B. Lipase
- C. Amylase
- D. Trypsin
Correct answer: C
Rationale: Amylase, produced by the pancreas and salivary glands, breaks down carbohydrates into simple sugars like glucose.
2. During which phase of the cardiac cycle do the atria contract, pushing blood into the ventricles?
- A. Atrial diastole
- B. Ventricular systole
- C. Atrial systole
- D. Ventricular diastole
Correct answer: C
Rationale: The correct answer is C: Atrial systole. During the cardiac cycle, the atria contract during atrial systole, pushing blood into the ventricles. This phase occurs after atrial diastole when the atria fill with blood. Ventricular diastole (option D) is when the ventricles relax and fill with blood, preparing for ventricular systole (option B), which is when the ventricles contract to pump blood out of the heart. Atrial systole is crucial for ensuring efficient filling of the ventricles before they contract, making it a key phase in the cardiac cycle.
3. 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.
4. What is the term for the reaction between an acid and a base to produce water and a salt?
- A. Combustion
- B. Neutralization
- C. Oxidation
- D. Decomposition
Correct answer: b
Rationale: Neutralization is the reaction between an acid and a base to produce water and a salt. The other choices do not accurately describe neutralization.
5. The term "barn" is a unit commonly used in nuclear physics to quantify:
- A. Energy (Electron volts are the standard unit for energy in nuclear physics)
- B. Radioactivity
- C. Nuclear cross-section
- D. Half-life
Correct answer: C
Rationale: The term 'barn' is a unit of measurement used in nuclear physics to quantify nuclear cross-section. Nuclear cross-section refers to the measure of the probability of a specific interaction occurring between particles during a nuclear reaction. The term 'barn' was coined based on its relation to the physical size of a nucleus, as it is a small unit of area used to describe the likelihood of a particle interacting with a nucleus. It is not used to quantify energy, radioactivity, or half-life, making options A, B, and D incorrect in this context.
6. Which word choice best fits the blank: "Her research paper was riddled with _____ errors."
- A. flagrant (obvious and inexcusable)
- B. cursory (superficial)
- C. innocuous (harmless)
- D. meticulous (carefully detailed)
Correct answer: A
Rationale: Option A "flagrant," emphasizes the severity and noticeable nature of the errors.
