Question 1 of 5
A nurse is assessing a client who has septic shock and is receiving dopamine by continuous IV infusion. Which of the following findings indicates that the nurse should increase the rate of infusion?
Correct Answer: B
Rationale: The correct answer is B: Hypotension. In septic shock, dopamine is used to increase blood pressure. Hypotension indicates that the current dosage is not effectively managing the client's blood pressure, necessitating an increase in the infusion rate to achieve the desired therapeutic effect. Headache (choice
A) is a common side effect of dopamine but does not directly correlate with the need for a dosage increase. Chest pain (choice
C) may indicate other issues but does not specifically warrant a change in dopamine infusion rate. Extravasation (choice
D) refers to the leakage of IV fluid into the surrounding tissue and requires immediate attention but is not directly related to adjusting the infusion rate of dopamine.
Question 2 of 5
A nurse is preparing to administer heparin subcutaneously to a client. Which of the following actions should the nurse plan to take to minimize bleeding following the injection?
Correct Answer: B
Rationale:
Correct
Answer: B: Grasp skin between thumb and forefinger throughout the injection.
Rationale: Grasping the skin between the thumb and forefinger helps to create tension at the injection site, which can help minimize bleeding after the injection. This technique helps to stabilize the skin and underlying tissues, reducing the risk of bruising or bleeding. It also ensures proper needle insertion and medication delivery without causing damage to the surrounding blood vessels or tissues.
Summary of Other
Choices:
A: Using the Z-track method is not necessary for subcutaneous injections, as it is primarily for intramuscular injections to prevent medication leakage.
C: Massaging the site can increase bleeding by causing further disruption of the blood vessels.
D: Aspirating the syringe is not needed for subcutaneous injections since the needle tip is not in a blood vessel.
Question 3 of 5
A nurse is preparing to transcribe a prescription for a client that reads 'ondansetron 8 mg by mouth every 12 hr PRN.' Which of the following parts of the prescription should the nurse clarify with the provider?
Correct Answer: D
Rationale: The correct answer is D: Reason. The nurse should clarify the reason for prescribing ondansetron to ensure understanding and appropriate administration. Frequency (
A) refers to how often the medication should be taken, route (
B) specifies how the medication should be administered, and dose (
C) indicates the amount of medication to give. Since the prescription already states the dose, route, and frequency, the reason for taking the medication needs clarification. It is crucial for the nurse to understand why the medication is prescribed to ensure it aligns with the client's needs and prevents errors.
Question 4 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 5 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.
