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

• A. Wheezing
• B. Difficulty breathing
• C. Chest tightness
• D. Fever

Correct answer: D

Rationale: The correct answer is D: "Fever." Fever is not a symptom commonly associated with asthma. Asthma symptoms typically include wheezing (A), difficulty breathing (B), and chest tightness (C). Wheezing is a high-pitched whistling sound that occurs during breathing, while difficulty breathing refers to the feeling of not getting enough air. Chest tightness is a common sensation of pressure or constriction in the chest. Fever is not a typical symptom of asthma but may occur in other respiratory conditions or infections. Therefore, fever is the correct answer as it does not align with the typical symptom profile of asthma.

2. Which macromolecule serves as the repository of genetic information in all living organisms?

• A. Ribonucleic acid (RNA)
• B. Deoxyribonucleic acid (DNA)
• C. Protein
• D. Carbohydrate

Correct answer: B

Rationale: Rationale: - DNA is the macromolecule that serves as the repository of genetic information in all living organisms. It carries the genetic instructions necessary for the growth, development, functioning, and reproduction of organisms. - RNA (option A) is involved in various cellular processes, including protein synthesis, but DNA is the primary molecule responsible for storing genetic information. - Proteins (option C) are essential for various cellular functions but do not serve as the primary repository of genetic information. - Carbohydrates (option D) are important for energy storage and structural support but do not store genetic information.

3. What is the main function of transition words and phrases in writing?

• A. To add unnecessary embellishments and fluff.
• B. To emphasize specific words or phrases in the text.
• C. To connect ideas smoothly and guide the reader's flow.
• D. To introduce opposing viewpoints and counterarguments.

Correct answer: C

Rationale: Transition words and phrases bridge ideas, create logical flow, and enhance the coherence of your writing.

4. When Harry uses team nursing as a care delivery system, he and his team need to assess the

• A. Each patient as listed on the worksheet
• B. Patients who needs least care
• C. Medications and treatments required for all patients
• D. Patients who need the most care

Correct answer: C

Rationale: When Harry uses team nursing as a care delivery system, he and his team need to assess the medications and treatments required for all patients. In team nursing, different team members are responsible for specific aspects of patient care, such as medications and treatments. Assessing the medications and treatments required for all patients ensures that each patient receives appropriate and timely care. This approach helps in coordinating care effectively among team members and prevents errors or omissions in patient treatment. Therefore, option C is the correct answer as it aligns with the principles of team nursing and patient-centered care.

5. Nutrients are absorbed into the bloodstream through which part of the digestive system?

• A. Stomach
• B. Large intestine
• C. Small intestine
• D. Esophagus

Correct answer: C

Rationale: The correct answer is C: Small intestine. The small intestine is where most of the absorption of nutrients takes place in the digestive system. Its inner lining is covered with tiny finger-like projections called villi, which increase the surface area for absorption. Nutrients such as carbohydrates, proteins, fats, vitamins, and minerals are absorbed into the bloodstream through the walls of the small intestine. The stomach primarily helps with the initial digestion of food, the large intestine absorbs water and salts, and the esophagus is the tube that carries food from the mouth to the stomach. Therefore, the small intestine is the main site of nutrient absorption in the digestive system.

6. Which structure connects the two hemispheres of the brain, allowing communication and coordination between them?

• A. Corpus callosum
• B. Thalamus
• C. Hypothalamus
• D. Medulla oblongata

Correct answer: a

Rationale: The correct answer is A: Corpus callosum. The corpus callosum is a broad band of nerve fibers that connects the left and right hemispheres of the brain, allowing them to communicate and coordinate with each other. It enables the transfer of information between the two hemispheres, which is essential for various functions such as sensory processing, motor coordination, and cognitive processes. The thalamus (B) is a different brain structure responsible for relaying sensory signals to the cerebral cortex, while the hypothalamus (C) regulates various vital functions such as body temperature, hunger, and hormone release. The medulla oblongata (D) is located in the brainstem and controls vital autonomic functions like breathing and heart rate. Therefore, the corpus callosum is the correct answer as it directly connects the two hemispheres of the brain for communication and coordination.
