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, the body's blood pressure drops significantly, leading to hypotension. Dopamine is a vasopressor that helps increase blood pressure by constricting blood vessels.
Therefore, if the client's blood pressure remains low despite being on dopamine, it indicates that the current rate of infusion is not sufficient to maintain adequate perfusion to vital organs. Increasing the rate of infusion would help improve blood pressure and perfusion.
Choices A, C, and D are incorrect as they are not directly related to the need for increasing the dopamine infusion rate in septic shock.
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 antiplatelet effects. Warfarin is an anticoagulant that works by inhibiting blood clot formation. Combining it with Ginkgo biloba, which also has anticoagulant properties, can lead to excessive bleeding. Coenzyme Q10 (
B), valerian (
C), and probiotics (
D) do not have significant interactions with warfarin.
Therefore, Ginkgo biloba is contraindicated for concurrent use with warfarin due to the increased risk of bleeding.
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 because propranolol is a beta-blocker that can slow down the heart rate. A heart rate of 56/min may indicate bradycardia, which can be a sign of overdose or adverse reaction to the medication. The nurse should intervene by assessing for symptoms of bradycardia and potentially contacting the healthcare provider.
Choices B, C, and D are within normal ranges and do not require immediate intervention.
Choice B indicates adequate oxygen saturation, choice C shows normal respiratory rate, and choice D represents a slightly low but acceptable blood pressure reading.
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 susceptible to potential adverse effects of the varicella vaccine. Live attenuated vaccines like the varicella vaccine can pose a risk of causing the actual disease in immunocompromised individuals.
Therefore, administering the varicella vaccine to a client with AIDS can lead to severe complications.
A: An older adult client living in a long-term care facility - Older adults are at increased risk for complications from varicella but it is not a contraindication.
B: A young adult who has an allergy to eggs - The varicella vaccine is made in eggs but having an egg allergy is not a contraindication.
C: A child who recently received the human papillomavirus vaccine - Receiving the HPV vaccine does not contraindicate receiving the varicella 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 in controlling 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 lowering cholesterol. Metformin (
D) is an antidiabetic medication. These choices are incorrect for treating severe vomiting as they do not have antiemetic properties.
