A nurse is preparing to administer quinapril 20 mg PO. Available is quinapril 40 mg tablets. How many tablets should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["0.5"]

To find the number of tablets,

we divide the total dosage in mg by the strength of each tablet in mg.

Let’s do the calculation:

Number of tablets=Strength of each tablet in mgTotal dosage in mg=40 mg/tablet20 mg=0.5 tablet

So, the nurse should administer 0.5 tablet of quinapril.

Correct Answer is D

Explanation

A) Take the medication at 1800, 30 min after the evening meal:

This interpretation is incorrect. Alendronate should be taken upon waking in the morning, at least 30 minutes before any food, fluids, or other medications. Taking it in the evening or after a meal would significantly reduce its absorption and effectiveness.

B) The client can return to bed after taking the medication, but before eating:

This interpretation is incorrect. The client needs to remain upright for at least 30 minutes after taking alendronate to prevent esophageal irritation or damage. Returning to bed shortly after taking the medication could lead to serious complications.

C) Over-the-counter oral preparations can be taken with this medication:

This interpretation is incorrect. Alendronate should be taken alone with a full glass of water. No other medications, including over-the-counter oral preparations, should be taken at the same time to ensure proper absorption and prevent interactions.

D) Choose the same day of each week to take this medication:

This is the correct interpretation. Alendronate is prescribed to be taken once per week, and choosing the same day each week helps maintain a consistent dosing schedule. This consistency is important for the medication's effectiveness in treating osteoporosis.

A. Take 15 mL 1 hr. after meals and at bedtime B. Take 2 drops four times daily C. Take 0.5 oz 30 min before meals and at bedtime. D. Take 1 tsp four times daily

Correct Answer is A

Explanation

A) Take 15 mL 1 hr. after meals and at bedtime:

This instruction uses milliliters (mL), which is a metric unit of volume. The metric system is widely used in medical settings for its precision and universality, making milliliters a standard measurement for liquid medications.

B) Take 2 drops four times daily:

This instruction uses drops as the unit of measurement. Drops are not a metric unit; they are a more general unit often used in prescribing liquid medications, especially for eye or ear drops, but they lack the precision of metric measurements.

C) Take 0.5 oz 30 min before meals and at bedtime:

This instruction uses ounces (oz), which are part of the imperial system, not the metric system. Ounces are commonly used in everyday measurements in some countries but are not the preferred unit in medical settings where metric units are standard.

D) Take 1 tsp four times daily:

This instruction uses teaspoons (tsp), which are not metric units. Teaspoons are part of the household measurement system and are less precise compared to metric units, which can lead to variations in dosing.
