ATI LPN Pharmacology Exam II Questions
Extract:
Question 1 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.
Question 2 of 5
The charge nurse has stated a client has hyperkalemia and needs cardiac monitoring. The nurse noted which of following lab values?
Correct Answer: D
Rationale: The correct answer is D: Potassium 5.7. In hyperkalemia, potassium levels are elevated, which can lead to cardiac arrhythmias. A potassium level of 5.7 indicates hyperkalemia and necessitates cardiac monitoring.
Choices A, B, and C have normal or low potassium levels, which would not require immediate cardiac monitoring.
Therefore, D is the correct choice for hyperkalemia.
Question 3 of 5
36.8 degrees centigrade is degrees farenheight. Round answer to nearest tenth.
Correct Answer: 98.2
Rationale:
To convert Celsius to Fahrenheit, you use the formula: F = (C x 1.8) + 32. So for 36.8°C, it would be (36.8 x 1.8) + 32 = 98.24°F, rounded to the nearest tenth is 98.2°F. The correct answer is 98.2 because this is the result of converting 36.8°C to Fahrenheit using the conversion formula. Other choices are incorrect because they do not align with the correct conversion calculation.
Question 4 of 5
The nurse is reviewing sources of medication information. The image below is which type of medication information:
Correct Answer: D
Rationale: The correct answer is D: Drug label. The image shown typically contains information such as drug name, dosage, expiration date, and manufacturer details. Drug labels are attached to medication containers and provide essential information for safe administration. Nursing drug guides (
A) are comprehensive references, package inserts (
B) are detailed leaflets inside medication packaging, and physician's drug references (
C) are resources for healthcare professionals. The other choices (E, F, G) are not applicable in this context.
Question 5 of 5
A nurse is caring for a client who is scheduled for a blood sampling for a serum creatinine level. The client asks the nurse, 'What is the purpose for this test?' Which of the following responses should the nurse give?
Correct Answer: A
Rationale:
Correct
Answer: A. This test will inform your provider how your kidneys are functioning.
Rationale: Serum creatinine is a waste product produced by muscles and excreted by the kidneys. Elevated levels indicate kidney dysfunction.
Therefore, this test is specifically designed to assess kidney function. The nurse's response should focus on accurately informing the client about the purpose of the test in relation to kidney function.
Summary of Incorrect
Choices:
B: Serum creatinine is not used to diagnose thyroid disorders.
C: Serum creatinine does not indicate the presence of an infection.
D: Serum creatinine is not a marker for anemia.
Therefore, choices B, C, and D are incorrect as they do not relate to the purpose of the serum creatinine test.
