Question 1 of 5
A nurse is preparing to mix short-acting insulin with NPH insulin from two vials. Which of the following actions should the nurse take?
Correct Answer: A
Rationale: The correct action is to inject air into the short-acting insulin vial before withdrawing it. This is because it prevents the formation of a vacuum in the vial, making it easier to withdraw the correct dose. Ensuring the NPH insulin is drawn first (
B) is incorrect because it may lead to contamination of one insulin with the other. Using two separate syringes (
C) is unnecessary and increases the risk of dosing errors. Administering the insulin within 20 minutes (
D) is not relevant to the mixing process.
Question 2 of 5
A nurse is caring for a client who is taking warfarin and reports taking several new herbal supplements. The nurse should identify that which of the following supplements is contraindicated for concurrent use with warfarin?
Correct Answer: C
Rationale: The correct answer is C: Ginkgo biloba. Ginkgo biloba can increase the risk of bleeding when taken with warfarin due to its anticoagulant properties. Warfarin also acts as a blood thinner, so combining it with Ginkgo biloba can lead to excessive bleeding. Valerian (
A) and Coenzyme Q10 (
D) are not known to interact significantly with warfarin. Probiotics (
B) are generally safe to use with warfarin and may even have beneficial effects on gut health.
Question 3 of 5
A nurse is caring for a client who has a sulfonamide allergy. Which of the following medications should the nurse identify as contraindicated?
Correct Answer: D
Rationale: The correct answer is D: Glyburide. Sulfonamide antibiotics and sulfonylurea medications like glyburide share a similar chemical structure, increasing the risk of cross-reactivity in individuals with sulfonamide allergies. Famotidine (
A) is an H2 blocker, not contraindicated in sulfonamide allergies. Aspirin (
B) is not contraindicated unless the individual has a specific aspirin allergy. Metronidazole (
C) is an antibiotic in a different class and not contraindicated in sulfonamide allergies. Thus, the nurse should identify glyburide as contraindicated due to the potential cross-reactivity in a client with a sulfonamide allergy.
Question 4 of 5
A nurse is planning to administer a controlled substance to a client who is experiencing pain. Which of the following actions should the nurse plan to take first?
Correct Answer: C
Rationale: The correct answer is C: Identify the client using two identifiers. This should be the first action because it ensures the right medication is being given to the right patient, which is crucial for patient safety. By confirming the client's identity with two identifiers (such as name and date of birth), the nurse minimizes the risk of medication errors. Documenting the administration of the medication (
A) should come after ensuring the correct patient is receiving it. Comparing medication amounts to inventory (
B) and removing medication from the cabinet (
D) are important steps but not as critical as confirming the patient's identity.
Question 5 of 5
A nurse accidentally administers metformin instead of metoprolol to a client. Which of the following actions should the nurse take?
Correct Answer: D
Rationale:
Correct
Answer: D (Check the client's glucose level)
Rationale: Metformin is a medication used to treat diabetes, so it is essential to check the client's glucose level after the accidental administration to monitor for hypoglycemia or hyperglycemia. This action is crucial for the client's safety and to initiate appropriate interventions promptly. Monitoring thyroid function levels (
Choice
A), uric acid level (
Choice
B), or HDL level (
Choice
C) would not directly address the immediate concern of potential glucose level abnormalities resulting from the administration error.
Therefore, checking the client's glucose level is the most appropriate action in this scenario.
