ATI LPN Pharmacology Exam II Questions
Question 1 of 5
What kind of syringe to you use for insulin injections?
Correct Answer: B
Rationale: The correct answer is B: U-50 or U-100 insulin syringe. Insulin is typically measured in units, not in milliliters, so using an insulin syringe calibrated in units (U-50 or U-100) ensures accurate dosing. A 1 mL TB syringe (
A) is not suitable as it measures in milliliters, not units. Using a 3 mL luer lock syringe (
C) can lead to dosing errors as it doesn't provide precise unit measurements needed for insulin injections. Choosing a syringe based on the type of insulin (
D) is unnecessary since all insulin types are dosed in units.
Question 2 of 5
A client tells the nurse they stopped taking a medication due to its side effects. Which of the following is a common cause of medication nonadherence?
Correct Answer: D
Rationale: The correct answer is D: Erectile dysfunction. Erectile dysfunction is a common side effect of many medications, causing embarrassment and affecting quality of life, leading individuals to discontinue the medication. Fatigue, vaginal discharge, and urinary frequency are not typically associated with medication side effects that would prompt nonadherence in the same way erectile dysfunction does.
Question 3 of 5
A client is on a blood thinner medication and requires weekly INR values. The nurse expects to see an INR of 2-2.5 times the normal range so she would anticipate what value:
Correct Answer: D
Rationale: The correct answer is D: 2.0-3.0. An INR value of 2-2.5 times the normal range is considered therapeutic for a client on a blood thinner medication. This range ensures that the blood is appropriately thinned to prevent clot formation while minimizing the risk of bleeding. A value below 1.0 (choice
A) would indicate insufficient anticoagulation, increasing the risk of clot formation. A range of 1.0-2.0 (choice
B) is below the desired therapeutic range for a client on blood thinners. A value above 3.0 (choice
C) would indicate excessive anticoagulation, increasing the risk of bleeding complications.
Therefore, choice D (2.0-3.0) is the most appropriate range for the client's INR values to ensure optimal therapeutic effects with minimal risks.
Question 4 of 5
A client has poor blood circulation. The nurse is concerned about which process of pharmacokinetics?
Correct Answer: A
Rationale:
Correct Answer: A (Distribution)
Rationale: Poor blood circulation affects the distribution of drugs in the body. It hinders the proper transport of drugs to target tissues, leading to suboptimal therapeutic effects. This can result in drug accumulation or toxicity due to decreased clearance. Distribution is a crucial phase of pharmacokinetics that involves the movement of drugs from the bloodstream to various body tissues. In the case of poor circulation, the drugs may not reach their intended sites of action efficiently, impacting their effectiveness.
Summary of other choices:
B: Excretion - Poor circulation does not directly affect the elimination of drugs from the body.
C: Metabolism - Poor circulation does not primarily impact the body's ability to metabolize drugs.
D: Absorption - Poor circulation mainly affects the distribution of drugs once they are absorbed into the bloodstream.
Question 5 of 5
A nurse is assisting with teaching a client about a new medication. Which of the following strategies should the nurse to use?
Correct Answer: D
Rationale: The correct answer is D: Use teach back method and active learning. This strategy ensures client understanding by having them repeat back information in their own words. This promotes active engagement and helps identify any misunderstandings.
Choice A is incorrect as it discourages client questions.
Choice B may not be appropriate for all clients and could potentially oversimplify important information.
Choice C is ineffective as it may confuse the client by presenting information in a non-sequential manner.
