1. When a patient is lying flat on their back, which of the following positions are they in?

Correct answer: B

Rationale: When a patient is lying flat on their back, they are in the supine position. In the supine position, the person's face is facing upward, and their back is touching the surface they are lying on. This position is commonly used for medical examinations and procedures. Choice A, 'Prone,' refers to lying face down, not on the back. Choice C, 'Lateral,' indicates lying on the side. Choice D, 'Medial,' pertains to the middle or center, not a position in relation to lying on the back.

2. What structures provide comprehensive protection for the brain?

Correct answer: D

Rationale: The brain is a vital organ that requires robust protection, which is provided by a combination of structures. The skull acts as a hard, protective covering for the brain, shielding it from external trauma and injury. The meninges encompass three layers of membranes (dura mater, arachnoid mater, and pia mater) that envelop the brain and spinal cord, offering additional protection and cushioning. Cerebrospinal fluid, a clear, colorless fluid surrounding the brain and spinal cord, acts as a shock absorber and provides nutrients to the central nervous system. The combined function of the skull, meninges, and cerebrospinal fluid ensures comprehensive protection for the brain, making option D, 'All of the above,' the correct answer. Choices A, B, and C are not individually sufficient to provide comprehensive protection, but together, they form a multi-layered defense system for the brain.

3. Which of the following is NOT a symptom of asthma, a chronic respiratory condition?

Correct answer: D

Rationale: The correct answer is 'Fever.' Fever is not a symptom commonly associated with asthma. Asthma symptoms typically include wheezing, difficulty breathing, and chest tightness due to inflammation and narrowing of the airways. Fever is more commonly seen in conditions such as infections or inflammatory diseases rather than asthma. Choices A, B, and C are common symptoms of asthma and are related to the constriction and inflammation of the airways, leading to breathing difficulties and chest discomfort.

4. What is the primary function of coronary arteries?

Correct answer: B

Rationale: The primary function of coronary arteries is to supply oxygenated blood to the heart muscle itself. The heart is a muscle that needs a constant supply of oxygen and nutrients to function properly. Coronary arteries branch off the aorta and specifically deliver oxygenated blood to the heart muscle, ensuring its proper function. Choice A is incorrect because coronary arteries do not deliver blood throughout the entire body but specifically to the heart. Choice C is incorrect as coronary arteries carry oxygenated blood away from the heart. Choice D is incorrect as the primary function of the coronary arteries is not to regulate blood pressure but rather to provide oxygenated blood to the heart muscle.

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

Correct answer: B

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
