1. Which of the following is a condition characterized by inflammation and narrowing of the airways, leading to symptoms such as wheezing, coughing, and shortness of breath?
- A. Pneumonia
- B. Tuberculosis
- C. Asthma
- D. Emphysema
Correct answer: C
Rationale: The correct answer is C: Asthma. Asthma is a chronic condition that involves inflammation and narrowing of the airways, leading to symptoms like wheezing, coughing, and shortness of breath. Pneumonia (A) is an infection of the lungs, not a chronic inflammatory condition like asthma. Tuberculosis (B) is a bacterial infection that primarily affects the lungs and does not typically manifest with symptoms like wheezing. Emphysema (D) is a lung condition characterized by damage to the air sacs in the lungs, not inflammation and narrowing of the airways like asthma.
2. An IV drip delivers medication at a rate of 40 drops per minute. Each drop contains 0.05 milliliters of the medication. How many milliliters of medication are delivered in one hour?
- A. 12 milliliters
- B. 24 milliliters
- C. 60 milliliters
- D. 120 milliliters
Correct answer: B
Rationale: First convert minutes to hours (1 hour * 60 minutes). Then, multiply the number of drops per minute (40 drops/minute) by the volume per drop (0.05 ml/drop) and by the conversion factor (60 minutes/hour) to find the total volume delivered: 40 drops/minute * 0.05 ml/drop * 60 minutes/hour = 24 milliliters.
3. Bradycardia refers to a heart rate that is:
- A. Normal (60-100 bpm)
- B. Slightly elevated (100-120 bpm)
- C. Significantly elevated (>120 bpm)
- D. Abnormally slow (<60 bpm)
Correct answer: D
Rationale: The correct answer is D. Bradycardia refers to an abnormally slow heart rate, typically defined as being less than 60 beats per minute (bpm). A heart rate of 60-100 bpm is considered normal, not bradycardia. Choices B and C incorrectly describe elevated heart rates, which are not characteristic of bradycardia. Therefore, option D is the most accurate description of bradycardia as it signifies a heart rate that is slower than normal.
4. What is the term for the maximum amount of solute that can dissolve in a solvent at a specific temperature and pressure?
- A. Molarity
- B. Solubility
- C. Concentration
- D. Saturation
Correct answer: b
Rationale: Solubility is the maximum amount of solute that can dissolve in a solvent at a specific temperature and pressure. The other choices do not accurately define solubility.
5. Salts are formed by the reaction between:
- A. Two acids
- B. An acid and a base
- C. Two bases
- D. A metal and a nonmetal only
Correct answer: B
Rationale: Salts are ionic compounds formed by the reaction of an acid and a base
6. A bookshelf has triangular shelves with a base of 40cm and a height of 30cm. The depth of the shelf is 25cm. What is the volume of each shelf?
- A. 3000 cu cm
- B. 3750 cu cm
- C. 5000 cu cm
- D. 7500 cu cm
Correct answer: B
Rationale: Calculate the area of the triangle (1/2 * base * height) and multiply by the depth.
