Question 1 of 5
A client has a new prescription for Clopidogrel. Which of the following instructions should the nurse include?
Correct Answer: B
Rationale: The correct answer is B: 'Avoid taking aspirin while on this medication.' Clopidogrel is an antiplatelet medication that can increase the risk of bleeding. Aspirin and other NSAIDs also affect platelet function and can further increase the risk of bleeding when combined with Clopidogrel. Therefore, it is important for the client to avoid taking aspirin while on this medication to reduce the risk of excessive bleeding. Choices A, C, and D are incorrect because there is no specific requirement to take Clopidogrel with food, avoid foods high in potassium, or take it at bedtime. The key instruction here is to avoid aspirin to prevent potential bleeding complications.
Question 2 of 5
A provider prescribes phenobarbital for a client who has a seizure disorder. The medication has a long half-life of 4 days. How many times per day should the nurse expect to administer this medication?
Correct Answer: A
Rationale: Phenobarbital has a long half-life of 4 days, meaning it remains at therapeutic levels in the body for an extended period. Due to this prolonged duration of action, the nurse should expect to administer phenobarbital once a day to maintain therapeutic levels and effectiveness. Administering it more than once a day would lead to unnecessary dosing and potential adverse effects as the medication remains active in the body for an extended period.
Question 3 of 5
A preschooler weighing 44 lb is to receive Amoxicillin 20 mg/kg/day PO divided equally every 12 hr. The available amoxicillin suspension is 250 mg/5 mL. How many mL should the nurse administer per dose?
Correct Answer: A
Rationale: To calculate the dosage per administration: First, convert the weight to kg (44 lb / 2.2 lb/kg = 20 kg). Then, calculate the required dosage per dose: (20 mg/kg/day x 20 kg) / 2 (for every 12 hr dosing) = 200 mg per dose. To determine the mL per dose, divide the required dosage by the concentration of the amoxicillin suspension: (200 mg / 250 mg) x 5 mL = 4 mL per dose. Therefore, the correct answer is 4 mL. Choice B (5 mL) is incorrect because the correct calculation yields 4 mL. Choices C (6 mL) and D (3 mL) are also incorrect as they do not align with the accurate calculation based on the provided information.
Question 4 of 5
A healthcare professional is preparing to initiate IV therapy for an older adult client. Which of the following actions should the professional plan to take?
Correct Answer: C
Rationale: Distending the veins using a blood pressure cuff is essential for facilitating visualization and access to the veins during IV catheter insertion. This technique helps healthcare professionals identify suitable veins, reducing the risk of complications like infiltration or hematoma formation. Using an electric shaver to remove hair on the extremity (Choice A) may increase the risk of micro-cuts and introduce infection. Selecting the antecubital area (Choice B) may not always be appropriate, as vein condition and accessibility vary among older adult clients. Instructing the client to keep the extremity still (Choice D) is important but is not directly related to preparing for IV therapy.
Question 5 of 5
A healthcare professional in a provider's office is reviewing the medical record of a client who is pregnant and is at her first prenatal visit. Which of the following immunizations may the healthcare professional administer safely to this client?
Correct Answer: C
Rationale: During pregnancy, it is safe for women to receive the inactivated influenza vaccine, which is recommended by healthcare providers to protect pregnant individuals from influenza. Vaccination with inactivated influenza vaccine during pregnancy not only provides protection to the pregnant individual but also confers passive immunity to the newborn during the vulnerable early months of life. The Varicella, Rubella, and Measles vaccines are live vaccines and are contraindicated during pregnancy due to the theoretical risk of transmission of the live virus to the fetus, which could potentially cause harm.
