A client asks why she needs to take a medication on an empty stomach. The nurse explains that food generally has which effect on drug dissolution and absorption?

Does not have an effect

Increases

Decreases

Enhances

Answer and Explanation

The Correct Answer is C

A) Does not have an effect: Food can significantly affect drug dissolution and absorption, so it is not accurate to say it has no effect. The presence of food in the gastrointestinal tract can alter how drugs are absorbed.

B) Increases: While food can sometimes increase the absorption of certain medications by stimulating digestive processes, it generally does not increase drug absorption for all medications. In many cases, food can delay or decrease the rate of drug absorption.

C) Decreases: Food commonly decreases the rate and extent of drug absorption. This can occur because food may bind to the drug, alter the pH of the stomach, or affect gastric emptying, leading to reduced drug dissolution and absorption.

D) Enhances: Food generally does not enhance drug dissolution and absorption for most medications. While some medications are better absorbed with food, in many cases, food can reduce the rate at which a drug is absorbed, leading to decreased efficacy.

Correct Answer is C

Explanation

A) 2 mg: This dosage is incorrect because it represents two milligrams, which is ten times the intended amount of two-tenths of a milligram (0.2 mg). The intended dosage is much smaller, so this option does not accurately represent the prescribed amount.

B) 0.20 mg: Although this representation is correct, the trailing zero is not necessary and can lead to potential confusion or errors. Standard practice often omits the trailing zero to simplify and clarify dosage instructions.

C) 0.2 mg: This is the most appropriate and clear way to write two-tenths of a milligram. It includes a leading zero before the decimal point, which is important for clarity and reducing the risk of misinterpretation. This format adheres to best practices in medication transcription.

D) 2.0 mg: This option is incorrect because it represents two milligrams, not two-tenths of a milligram. The decimal point and trailing zero do not change the fact that the dosage is significantly larger than what is intended.

A. Report the incident immediately to your supervisor upon noticing. B. Gather reversal agents to administer to the client C. Notify the client's provider immediately while present with the client. D. Assess the client's vital signs.

Correct Answer is D

Explanation

A) Report the incident immediately to your supervisor upon noticing: Reporting the incident is an important step, but it should come after assessing the client's condition. Immediate assessment of the client's vital signs and overall status takes precedence to address any potential immediate health impacts due to the medication error.

B) Gather reversal agents to administer to the client: Gathering reversal agents is a critical step if the medication administered poses an immediate risk and reversal is necessary. However, this action should follow an initial assessment of the client's condition to determine if reversal is needed.

C) Notify the client's provider immediately while present with the client: Notifying the provider is essential to receive guidance on how to manage the medication error. Nonetheless, the first priority should be to assess the client's condition to provide accurate information to the provider.

D) Assess the client's vital signs: The initial action should be to assess the client’s vital signs and overall condition to determine any immediate effects of the incorrect medication. This assessment helps in identifying if the client is experiencing any adverse reactions or complications, which will guide subsequent actions such as notifying the provider and administering reversal agents if needed.
