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, hypotension is a common sign of inadequate tissue perfusion. Dopamine is a vasopressor that helps increase blood pressure by constricting blood vessels.
Therefore, if the client is still hypotensive despite receiving dopamine, it indicates that the current infusion rate is not sufficient to maintain adequate perfusion. Increasing the infusion rate can help improve blood pressure and perfusion.
Incorrect choices:
A: Headache - Not a direct indication of dopamine infusion rate adjustment.
C: Chest pain - Not a direct indication of dopamine infusion rate adjustment.
D: Extravasation - Indicates leakage of medication from the IV site, not a need to adjust infusion rate.
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 which of the following supplements is contraindicated for concurrent use with warfarin?
Correct Answer: A
Rationale: The correct answer is A: Ginkgo biloba. Ginkgo biloba can increase the risk of bleeding when taken with warfarin due to its anticoagulant properties, potentially leading to serious complications. Coenzyme Q10 (
Choice
B), Valerian (
Choice
C), and Probiotics (
Choice
D) do not have significant interactions with warfarin. Ginkgo biloba is the only supplement in the list known to interact adversely with warfarin.
Question 3 of 5
A nurse is assessing a client with hypertension who is receiving propranolol. Which of the following findings requires the nurse's intervention?
Correct Answer: A
Rationale: The correct answer is A: Heart rate of 56/min. Propranolol is a beta-blocker that can cause bradycardia as a side effect. A heart rate of 56/min is lower than the normal range, indicating bradycardia. This finding requires the nurse's intervention as it can lead to decreased cardiac output and potential complications.
Choice B (Sa02 95% on 2 L/min of oxygen) indicates adequate oxygen saturation and does not require immediate intervention.
Choice C (Respirations 22/min) falls within the normal range and does not require immediate intervention.
Choice D (Blood pressure 106/68 mm Hg) is within normal limits for a client with hypertension on propranolol and does not require immediate intervention.
Question 4 of 5
A nurse is preparing to administer the varicella vaccine to a group of clients. The nurse should identify which of the following clients as having a contraindication for receiving this immunization?
Correct Answer: D
Rationale: The correct answer is D: A client who has AIDS. Clients with AIDS have compromised immune systems, making them more vulnerable to potential complications from live vaccines like the varicella vaccine. The live varicella vaccine could lead to serious infections in individuals with weakened immune systems.
Incorrect
Choices:
A: An older adult client living in a long-term care facility - Advanced age alone is not a contraindication for varicella vaccine.
B: A young adult who has an allergy to eggs - The varicella vaccine is not contraindicated in individuals with egg allergies.
C: A child who recently received the human papillomavirus vaccine - There is no contraindication for receiving the varicella vaccine after the HPV vaccine.
Question 5 of 5
A nurse is caring for a client who is experiencing severe vomiting. Which of the following medications should the nurse plan to administer?
Correct Answer: C
Rationale: The correct answer is C: Prochlorperazine. This medication is an antiemetic that helps to control severe vomiting. It works by blocking dopamine receptors in the brain, reducing nausea and vomiting. Propafenone (
A) is an antiarrhythmic drug, not indicated for vomiting. Simvastatin (
B) is a statin used for cholesterol management, unrelated to vomiting. Metformin (
D) is an antidiabetic drug, not used for vomiting. In summary, prochlorperazine is the appropriate choice for managing severe vomiting due to its antiemetic properties.
