Literature review reveals that a new drug has a median lethal dose of 10 and a median effective dose of 5. The nurse determines that an error in which _____ times the correct dose is given could be lethal. Standard Text: Record your answer rounding to the nearest whole number.

Fill in the blank(s) with correct word

Question 2

The nurse is reviewing the medication administration record for a group of patients and recognizes that which agents have nonspecific cellular responses? Note: Credit will be given only if all correct choices and no incorrect choices are selected. Standard Text: Select all that apply.

1. Ethyl alcohol
2. General anesthetics
3. Osmotic diuretics
4. Calcium channel blockers
5. Alpha-adrenergic antihypertensives

Answer to Question 1

2
Rationale: x = 10/5; solving for x, the therapeutic index would be 2. This means it would only take an error in magnitude of approximately 2 times the average dose to be lethal.
Global Rationale: x = 10/5; solving for x, the therapeutic index would be 2. This means it would only take an error in magnitude of approximately 2 times the average dose to be lethal.

Answer to Question 2

1,2,3
Rationale 1: Ethyl alcohol is an example of an agent that acts by nonspecific mechanisms, independently of cellular receptors.
Rationale 2: General anesthetics are an example of agents that act by nonspecific mechanisms, independently of cellular receptors.
Rationale 3: Osmotic diuretics are an example of agents that act by nonspecific mechanisms, independently of cellular receptors.
Rationale 4: Calcium channel blockers have a specific mechanism of action.
Rationale 5: Alpha-adrenergic antihypertensives have a specific mechanism of action.
