ATI LPN Pharmacology Exam II Questions
Extract:
Question 1 of 5
A nurse is reinforcing teaching with a group of nurses about medication administration. Which of the following routes of administration provides the most rapid onset for the client?
Correct Answer: A
Rationale: The correct answer is A: intravenous. Intravenous administration provides the most rapid onset because the medication is directly delivered into the bloodstream, bypassing the absorption process. This allows for immediate systemic distribution and action.
Topical patch (
B) is absorbed through the skin and has a slower onset. Sublingual (
C) administration involves absorption through the mucous membranes under the tongue, which is faster than oral but still slower than intravenous. Intramuscular (
D) administration involves absorption through muscle tissue, which is slower than intravenous due to the need for absorption into the bloodstream.
Question 2 of 5
The nurse is reviewing concepts of pharmacokinetics with a group of student nurses. The student correctly identifies the timing of the peak effect
Correct Answer: B
Rationale: The correct answer is B: How long it will take to see the maximum effect of the medication. The peak effect refers to the time when the medication reaches its highest concentration in the bloodstream, resulting in the maximum therapeutic effect. This is important for determining the optimal timing of medication administration to achieve the desired outcome.
Choices A, C, and D are incorrect because they do not specifically address the concept of peak effect. Option A focuses on the duration of medication effects rather than the timing of the peak effect. Option C refers to the onset of therapeutic effect, which is different from the peak effect. Option D describes the concept of half-life, which is unrelated to the timing of peak effect.
Question 3 of 5
The nurse is caring for a post-surgical patient who was prescribed controlled substances classified schedule IV substances as:
Correct Answer: D
Rationale: The correct answer is D: having a low potential for psychological or physical dependence. Schedule IV substances have a lower potential for abuse and dependence compared to other schedules. These drugs are considered to have a relatively low risk of addiction or dependence when used appropriately. This classification is based on their recognized medical benefits and lower abuse potential.
Choices A, B, and C are incorrect because they describe characteristics of substances in higher schedule categories (such as schedules I, II, or III) which have higher potential for abuse and dependence.
Therefore, the correct answer is D as it accurately reflects the classification of schedule IV substances.
Question 4 of 5
A length of 55 cm's is equal to inches. Round answer to nearest whole number (numeric value only)
Correct Answer: 22
Rationale:
To convert cm to inches, we use the conversion factor 1 inch = 2.54 cm. So, 55 cm ÷ 2.54 = 21.65354 inches. Rounding to the nearest whole number, we get 22 inches.
Therefore, the correct answer is 22.
Incorrect options:
A: 24 - Incorrect, as it is not the nearest whole number to the actual conversion.
B: 20 - Incorrect, as it is lower than the actual conversion.
C: 18 - Incorrect, as it is much lower than the actual conversion.
D: 26 - Incorrect, as it is higher than the actual conversion.
E: 28 - Incorrect, as it is much higher than the actual conversion.
F: 16 - Incorrect, as it is significantly lower than the actual conversion.
G: 30 - Incorrect, as it is significantly higher than the actual conversion.
Question 5 of 5
A nurse is reviewing a new prescription for a client. The nurse should identify that which of the following abbreviations used by the provider indicates 'to administer medications before meals'?
Correct Answer: D
Rationale: The correct answer is D: AC. The abbreviation 'AC' stands for 'ante cibum,' which means 'before meals.' This indicates the timing of when the medication should be administered.
Choice A, NG, refers to nasogastric route, choice B, T, means 'take,' and choice C, DNR, stands for 'do not resuscitate,' which are not related to administering medications before meals.
