ATI PN Pharmacology 2020 Exam 2 Questions
Extract:
Question 1 of 5
A nurse is preparing to mix NPH insulin and regular insulin for administration. Which of the following actions should the nurse take?
Correct Answer: B
Rationale: The correct answer is B: Inject air into each vial. This step is necessary to prevent creating a vacuum in the vial, making it easier to withdraw the correct amount of insulin. Injecting air into the vial equalizes the pressure, allowing for smooth withdrawal of the medication.
Choice A is incorrect because withdrawing the NPH insulin first without injecting air into the vials may lead to difficulty in withdrawing the correct amount of insulin due to pressure differences.
Choice C is incorrect as a tuberculin syringe is not typically used for insulin administration.
Choice D is incorrect because shaking the regular insulin vial may cause frothing, affecting the accuracy of the dose measurement.
Question 2 of 5
A nurse is caring for a client who started taking amitriptyline 6 days ago. The client reports that the medication is not helping. Which of the following responses should the nurse make?
Correct Answer: D
Rationale: The correct response is D: "You will need to wait a couple of weeks to feel the therapeutic effect of the medication." Amitriptyline is a tricyclic antidepressant that typically takes 2-4 weeks to reach its full therapeutic effect. It is important for the nurse to educate the client on the delayed onset of action to manage expectations.
Choice A is incorrect as it is premature to switch medications after only 6 days.
Choice B is incorrect because increasing the dose without allowing sufficient time for the medication to work may lead to unnecessary side effects.
Choice C is incorrect as amitriptyline does not need to be taken on an empty stomach for effectiveness.
Question 3 of 5
A nurse is assisting in the care of a client who is receiving morphine via a continuous epidural infusion. Which of the following findings should the nurse report to the provider immediately?
Correct Answer: B
Rationale: The correct answer is B: Respiratory rate 10/min. This finding should be reported immediately because it indicates respiratory depression, a serious side effect of morphine. A respiratory rate of 10/min is below normal range (12-20/min) and can lead to hypoxia and respiratory arrest. Prompt intervention is crucial to prevent further complications.
Other choices are incorrect because:
A: Constipation is a common side effect of morphine but does not require immediate reporting.
C: Facial flushing is a common side effect of morphine and does not indicate a medical emergency.
D: Blood pressure of 88/56 mm Hg is low, but not as critical as respiratory depression in this context.
Question 4 of 5
A nurse is preparing to identify a client prior to medication administration. Which of the following questions should the nurse ask to determine the client's identity?
Correct Answer: C
Rationale: The correct answer is C: Is your name Sarah Jones? This question helps verify the client's identity by confirming their name, a key identifier for medication administration. Asking about age (
A) or room number (
B) does not directly confirm identity. Inquiring about a home phone number (
D) is not as reliable as the client may provide incorrect information. Other choices (E, F, G) are irrelevant. Thus, confirming the client's name is crucial for accurate medication administration.
Question 5 of 5
A nurse is collecting data from a client who has a new prescription for amoxicillin. Which of the following findings indicates that the client is having an allergic reaction to the medication?
Correct Answer: B
Rationale: The correct answer is B: Wheezing. Wheezing is a common symptom of an allergic reaction to medications like amoxicillin due to bronchoconstriction. This indicates the client is experiencing an allergic response. Bradycardia (
A) is not typically associated with amoxicillin allergies. Polyuria (
C) refers to excessive urination and is not a common allergic reaction symptom. Bruising (
D) is unrelated to amoxicillin allergies. In summary, wheezing is a key indicator of an allergic reaction to amoxicillin, making it the correct choice.
