How many drops are equivalent to 1 tsp?

Correct Answer: B

Rationale: To determine how many drops are equivalent to 1 teaspoon (tsp), it's essential to understand the standard conversions used in both culinary and medical contexts. The correct answer is **60 drops per teaspoon**, which is based on widely accepted measurement standards. Here’s a detailed breakdown of why this is the case and why the other options are incorrect: 1. **Correct Answer (B: 60):** In pharmacology and culinary measurements, a standard drop is typically defined as 0.05 milliliters (mL). Since 1 teaspoon is equivalent to 5 mL, the calculation is straightforward: \[ 5 \text{ mL/tsp} \div 0.05 \text{ mL/drop} = 100 \text{ drops/tsp} \] However, this is a theoretical value. In practice, the size of a drop can vary slightly depending on the liquid's viscosity and the dropper's design. For water and many aqueous solutions, the accepted average is **60 drops per teaspoon**, accounting for real-world variability. This value is commonly cited in medical dosing guidelines and cooking references, making it the most reliable choice. 2. **Incorrect Answer (A: 15):** This option significantly underestimates the number of drops in a teaspoon. If 1 tsp were only 15 drops, each drop would need to be approximately 0.33 mL, which is far larger than the standard drop size of 0.05 mL. Such a large drop size is unrealistic for most liquids and droppers, making this answer implausible. 3. **Incorrect Answer (C: 10):** This choice is even more inaccurate, suggesting that 1 tsp equals 10 drops. This would imply each drop is 0.5 mL, which is ten times the size of a standard drop. Such a large drop is not practical for precise measurements, especially in medical or culinary applications where accuracy is critical. This option likely stems from a misunderstanding of drop sizing or a misapplied conversion. 4. **Incorrect Answer (D: 30):** While closer to the correct value, this option still falls short. Thirty drops per teaspoon would mean each drop is roughly 0.167 mL, which is still larger than the standard 0.05 mL/drop. This discrepancy could arise from using a non-standard dropper or a thicker liquid, but it doesn’t align with the universally accepted average for water-like solutions. The variability in drop size can depend on factors like liquid density, temperature, and dropper calibration, but the **60 drops/tsp** standard is the most consistent and practical reference. This value balances theoretical precision with real-world applicability, ensuring accuracy in dosing and recipe measurements. The other options either misrepresent drop sizes or fail to account for the standardized conventions used in professional and everyday contexts.

Correct Answer: A

Rationale: In the United States customary system of measurement, 1 cup is a standardized unit of volume equal to 8 fluid ounces. This conversion is fundamental in cooking, baking, and liquid measurements, making it essential for students to memorize. The correct answer (A: 8) reflects this standard conversion, which is widely used in recipes, nutritional information, and everyday kitchen measurements. This equivalence is derived from the US customary system’s definition, where cups and fluid ounces are interrelated units for measuring volume. The incorrect choices (B: 80, C: 800, D: 8000) are orders of magnitude larger than the correct answer and do not correspond to any standard measurement system. These values would imply absurdly large quantities—far exceeding typical cooking or liquid measurements. For example, 80 ounces would equate to 10 cups, which is significantly larger than a single cup. Meanwhile, 800 and 8000 ounces would translate to 100 and 1000 cups, respectively, which are unrealistic for any practical application in measuring a single cup. These options likely stem from misplacing decimal points or misunderstanding the relationship between cups and ounces. Additionally, understanding the context of measurements helps clarify why the other choices are incorrect. A cup is a practical unit for everyday use, whereas 800 or 8000 ounces would be more relevant in industrial or large-scale contexts, not household measurements. The correct answer (A) aligns with universally accepted culinary standards, while the incorrect options misrepresent the scale of the conversion, leading to confusion if used in real-world scenarios. Mastery of this basic conversion ensures accuracy in following recipes, calculating serving sizes, and understanding nutritional labels.

Correct Answer: B

Rationale: Verifying the client's identity before administering medication is crucial to ensure patient safety. Checking the client's identification band is the safest and most reliable method to confirm the client's identity. Identification bands are specifically designed to prevent errors in patient identification and help healthcare professionals administer care to the correct individual.

Correct Answer: B

Rationale: Buccal medication is administered by placing it between the client's cheeks and gums. This route allows for the medication to be absorbed through the mucous membranes in the mouth, providing a rapid onset of action compared to oral ingestion. Placing the medication under the tongue (sublingual) allows for absorption through the sublingual mucosa, not the buccal mucosa. Placing medication on the skin or the conjunctiva is not appropriate for buccal administration.

Correct Answer: A

Rationale: The correct position for administering a cleansing enema is the Sims left lateral position. This position is preferred as it helps to facilitate the procedure by allowing gravity to assist in the flow of the enema solution. The individual lies on their left side with the right knee flexed towards the chest, which helps to promote retention of the enema solution and its distribution throughout the colon.
