1. Temperature Conversion & Interpretation: A patient's body temperature is 102°F. Convert this to °C and assess if it indicates a fever.

• A. 37°C (Normal)
• B. 39°C (Low-grade fever)
• C. 39°C (Fever)
• D. 42°C (Hyperthermia)

Correct answer: C

Rationale: Rationale: 1. To convert Fahrenheit to Celsius, you can use the formula: °C = (°F - 32) x 5/9. 2. Given that the patient's body temperature is 102°F, we can calculate the equivalent temperature in Celsius: °C = (102 - 32) x 5/9 °C = 70 x 5/9 °C = 350/9 °C ≈ 38.9°C, which can be rounded to 39°C. 3. A body temperature of 39°C is considered to indicate a fever. Normal body temperature typically ranges from 36.1°C to 37.2°C, so a temperature of 39°C is higher than the normal range and suggests a fever. 4. Options A and B are incorrect as they do not reflect the conversion of 102°F to °C

2. he adrenal cortex produces a group of steroid hormones called corticosteroids. What is a MAJOR function of corticosteroids?

• A. Regulate insulin sensitivity and blood sugar levels
• B. Control blood pressure and electrolyte balance
• C. Stimulate the immune system and inflammatory response
• D. Promote growth and development during puberty

Correct answer: B

Rationale: The correct answer is B: 'Control blood pressure and electrolyte balance.' Corticosteroids, produced by the adrenal cortex, play a major role in regulating blood pressure and electrolyte balance in the body. These hormones, such as aldosterone, act on the kidneys to control the reabsorption of sodium and water, which in turn affects blood pressure and electrolyte levels. While corticosteroids can have effects on other physiological processes, their primary function is to regulate blood pressure and electrolyte balance, making option B the most appropriate choice in this context.

3. Stephanie is often seen interacting with the medical intern during coffee breaks and after duty

• A. Formal
• B. Informal
• C. Staff
• D. Line

Correct answer: B

Rationale: The correct answer is 'B: Informal.' Stephanie's interactions with the medical intern during coffee breaks and after duty suggest a casual and friendly relationship, rather than a formal or official one. 'Informal' describes interactions that are relaxed, personal, and not bound by strict professional protocols. In contrast, 'formal' interactions would involve more structured and official communication, such as meetings or professional discussions. 'Staff' and 'line' are not relevant in this context, as they do not describe the nature of the relationship between Stephanie and the medical intern.

4. Differentiate between gene therapy and genetic engineering in the context of human intervention.

• A. Gene therapy aims to modify existing genes within body cells, while genetic engineering manipulates genes in embryos to be passed on to offspring.
• B. Gene therapy focuses on treating genetic diseases, while genetic engineering enhances desirable traits or eliminates undesirable ones.
• C. Both involve directly altering the DNA sequence, but gene therapy targets somatic cells and genetic engineering modifies germline cells.
• D. There is no fundamental difference; both terms are synonymous.

Correct answer: B

Rationale: Rationale: A) Incorrect. Gene therapy does aim to modify existing genes within body cells, but genetic engineering does not necessarily manipulate genes in embryos to be passed on to offspring. Genetic engineering can involve modifying genes in any type of cell, not just embryos. B) Correct. Gene therapy is a medical intervention that aims to treat genetic diseases by correcting or replacing faulty genes within an individual's body cells. On the other hand, genetic engineering involves modifying genes to enhance specific traits or eliminate undesirable ones, often in the context of agriculture or biotechnology. C) Incorrect. While both gene therapy and genetic engineering involve altering DNA sequences, the distinction lies in the target cells. Gene therapy targets somatic cells (non-reproductive cells), while genetic engineering typically involves modifying germline cells (reproductive cells that can pass on genetic changes to offspring). D) Incorrect. There is

5. What is the periodic law?

• A. The statement that the properties of the elements are a periodic function of their atomic numbers.
• B. The statement that the elements can be arranged in a table in which elements with similar properties are grouped together
• C. The statement that the elements can be arranged in a table in which the atomic number of an element is equal to the number of protons in its nucleus
• D. The statement that the elements can be arranged in a table in which the atomic mass of an element is equal to the number of neutrons in its nucleus.

Correct answer: A

Rationale: The periodic law states that the properties of elements are a periodic function of their atomic numbers. This means that when elements are arranged in order of increasing atomic number, there is a periodic repetition of their properties. This forms the basis for the modern periodic table. Option B describes the periodic table itself, while options C and D do not accurately describe the periodic law.

6. What is the relationship between the frequency and wavelength of a wave?

• A. Inversely proportional
• B. Directly proportional
• C. No relationship
• D. Depend on the medium

Correct answer: a

Rationale: Frequency and wavelength have an inverse relationship - as one increases, the other decreases.
