ATI LPN Pharmacology Exam II Questions
Extract:
Question 1 of 5
A nurse is reinforcing teaching with a client scheduled for activated partial thromboplastin time (aPTT) testing. Which of the following statements made by the client indicates understanding of the teaching?
Correct Answer: B
Rationale: The correct answer is B: This test measures deficiencies in clotting factors. The activated partial thromboplastin time (aPTT) test is used to assess the intrinsic pathway of the clotting cascade and to monitor the effectiveness of anticoagulant therapy. A client understanding that the test measures deficiencies in clotting factors demonstrates comprehension of the purpose of the test.
Incorrect choices:
A: This test does not show dehydration status.
C: Sodium intake is not related to aPTT levels.
D: The aPTT test is not used to measure blood sugar levels.
Therefore, choice B is the correct answer as it aligns with the purpose of the aPTT test in evaluating clotting factor deficiencies.
Question 2 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 3 of 5
A nurse is receiving a telephone prescription for a client and documents it as metformin 500 PO BID. Which of the following elements should the nurse identify is missing from the prescription?
Correct Answer: A
Rationale: The correct answer is A: Dosage. In the prescription "metformin 500 PO BID," metformin is the medication, 500 is the dosage, PO means by mouth (route), and BID stands for twice a day (time/frequency). The missing element is the specific dosage form (e.g., tablets, milliliters) of metformin, which is crucial for accurate administration.
Choices B, C, and D are all included in the prescription, making them incorrect.
Choices E, F, and G are not applicable in this context.
Therefore, the nurse should identify the missing element as the dosage to ensure safe and effective medication administration.
Question 4 of 5
The nurse is collecting data for a client suspected of a drug overdose and notes the clients has slow breathing and decreased blood pressure. The nurse correctly documents these findings as:
Correct Answer: D
Rationale: The correct answer is D: Bradypnea and hypotension. Bradypnea refers to slow breathing, which is indicative of respiratory depression commonly seen in drug overdose. Hypotension, or decreased blood pressure, can also occur due to the depressive effects of certain drugs. Tachypnea (choice
A) is rapid breathing, which is opposite to what is observed in the client. Hypertension (choices B and
C) is increased blood pressure, which is not consistent with the findings of decreased blood pressure in the client.
Therefore, choices A, B, and C can be ruled out. The correct answer, D, aligns with the assessment findings of slow breathing and decreased blood pressure in a client suspected of a drug overdose.
Question 5 of 5
In any group of 100 nurses, you would expect 45 nurses to specialize in a particular field. In a class of 240 graduates, how many would you expect to specialize?
Correct Answer: 108
Rationale:
Rationale: In a group of 100 nurses, 45 specialize. So, the proportion of nurses specializing is 45/100 = 0.45.
To find how many graduates specialize, we apply this proportion to the class size: 0.45 x 240 = 108. Thus, you would expect 108 graduates to specialize. Other choices are incorrect because they do not follow this logical calculation based on the given proportion.
