A client is prescribed a loading dose of a cardiac glycoside for an exacerbation of heart failure. When the client comments, I usually take a much lower dose, which response by the nurse is the most appropriate?

1. Giving a large dose will reduce the incidence of side effects.
2. You are being given a large dose in order to increase blood levels of the drug quickly.
3. The health care provider ordered this dose, so I need to administer it.
4. Your usual dose is probably no longer effective for your condition, and you need to be on a higher dose now.

Question 2

The nurse is teaching a client about the loading dose of antibiotic that will be administered later in the day.

The client demonstrates understanding by stating that the medication will reach a therapeutic dose in____ hour(s) versus the 48 hours that would be required for the routine medication dose.
Fill in the blank with the appropriate word.

Answer to Question 1

Correct Answer: 2
Rationale 1: Giving a larger dose actually could increase the incidence of side effects.
Rationale 2: Loading doses of medications are used to provide a more rapid increase in the blood level of the drug, resulting in a quicker therapeutic response.
Rationale 3: Although this is an accurate statement, it does not provide an explanation to the client as to why a larger dose is being administered.
Rationale 4: A loading dose is usually only given once, and the client will then be put back on the average daily dose.

Answer to Question 2

Correct Answer: 12
Rationale: It takes almost five doses (48 hours) before a therapeutic level is reached using a routine dosing schedule. With a loading dose, a therapeutic level is reached within 12 hours.
