Biology
1. Which of the following is the main function of the pancreas?
- A. To store food and break it down into smaller pieces
- B. To absorb nutrients into the bloodstream
- C. To produce enzymes that help digest food
- D. To regulate blood sugar levels
Correct answer: C
Rationale: Rationale: The pancreas is a vital organ in the digestive system that produces digestive enzymes such as amylase, lipase, and proteases. These enzymes are released into the small intestine to help break down carbohydrates, fats, and proteins in food, aiding in the digestion and absorption of nutrients. Options A and B are incorrect because the pancreas is not involved in storing or absorbing nutrients. Option D is partially correct as the pancreas also plays a role in regulating blood sugar levels by producing insulin and glucagon, but its primary function is to produce digestive enzymes.
2. the relationship between the Pauli exclusion principle and the structure of the atom?
- A. It defines the maximum number of electrons allowed in each energy level
- B. It explains why oppositely charged particles attract each other
- C. It describes the wave-particle duality of electrons
- D. It determines the arrangement of protons and neutrons in the nucleus
Correct answer: A
Rationale: The Pauli exclusion principle states that no two electrons in an atom can occupy the same quantum state, dictating the maximum number of electrons allowed in each energy level and influencing the overall structure of the atom's electron cloud.
3. Which of the following numbers is a perfect square?
- A. 10
- B. 12
- C. 15
- D. 16
Correct answer: D
Rationale: A perfect square is a number obtained by squaring an integer. 16 is the result of squaring 4 (4 x 4 = 16). The other answer choices are not the product of squaring any whole number.
4. The feedback loop is a crucial concept in endocrine regulation. In a negative feedback loop, high levels of a hormone can:
- A. Further stimulate the release of the same hormone
- B. Inhibit the release of the hormone or its production
- C. Have no effect on the hormone's regulation
- D. Increase the need for another hormone entirely
Correct answer: B
Rationale: In a negative feedback loop, high levels of a hormone signal the body to stop producing more of that hormone in order to maintain homeostasis. This is a self-regulating mechanism to prevent excessive levels of the hormone. Option B is correct because in this scenario, the high levels of the hormone will inhibit its further release or production. This feedback loop helps ensure that hormone levels stay within a narrow range, preventing overstimulation or imbalance in the endocrine system. Options A, C, and D are incorrect as they do not align with the concept of negative feedback regulation in endocrine systems.
5. Identify the adverb in the following sentence: The patient waited anxiously for the doctor's news.
- A. waited
- B. anxiously
- C. doctor's
- D. news
Correct answer: B
Rationale: Adverbs modify verbs, adjectives, or other adverbs. In this sentence, "anxiously" describes how the patient "waited".
6. Ms. Valencia prepares the process standards. Which of the following is NOT a process
- A. Initial assessment shall be done to all patients within twenty four hours upon admission.
- B. Informed consent shall be secured prior to any invasive procedure
- C. Patients’ reports 95% satisfaction rate prior to discharge from the hospital.
- D. Patient education about their illness and treatment shall be provided for all patients and their
Correct answer: D
Rationale: In this question, Ms. Valencia is tasked with preparing process standards, which are systematic procedures or steps followed to ensure quality care. Options A, B, and C all refer to specific processes that are essential in healthcare: timely assessment, obtaining informed consent, and assessing patient satisfaction. However, option D about providing patient education is more focused on an outcome (patient education) rather than a specific process standard. While patient education is important, the question is asking for a process standard, making option D the correct answer as it does not directly relate to a specific process standard.
