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, with a long half-life of 4 days, remains at therapeutic levels in the body for an extended period. Due to this prolonged duration of action, the nurse should administer phenobarbital once a day to maintain a consistent therapeutic effect without the need for multiple daily doses. Administering the medication more than once a day would not be necessary and could increase the risk of side effects or toxicity. Therefore, the correct answer is to administer phenobarbital once a day.

Correct Answer: A

Rationale: To calculate the dosage per administration: Convert the weight to kg (44 lb / 2.2 lb/kg = 20 kg). Then, (20 mg/kg/day x 20 kg) / 2 (for every 12 hr dosing) = 200 mg per dose. (200 mg / 250 mg) x 5 mL = 4 mL per dose. Therefore, the nurse should administer 4 mL of amoxicillin suspension per dose. Choice B, 5 mL, is incorrect because the calculation shows that 4 mL is the correct dose. Choices C and D are also incorrect as they are not in line with the calculated dosage based on the weight of the child and the concentration of the medication.

Correct Answer: C

Rationale: The correct answer is C. The healthcare professional should distend the veins using a blood pressure cuff to make the veins more visible and accessible for IV catheter insertion. This technique helps reduce the risk of overfilling the vein, which can lead to complications such as hematoma formation. Choices A, B, and D are incorrect because while selecting the antecubital area is often appropriate for IV insertion in adults, the key action in this scenario is to distend the veins using a blood pressure cuff to facilitate the procedure.

Correct Answer: C

Rationale: The correct answer is C, the inactivated influenza vaccine. During pregnancy, the Centers for Disease Control and Prevention (CDC) recommend the inactivated influenza vaccine as safe for pregnant individuals. This vaccination is crucial to protect both the pregnant person and their developing baby from influenza-related complications. It is essential to avoid live vaccines, such as varicella (chickenpox), rubella, and measles vaccines during pregnancy due to the theoretical risk of harm to the fetus. Choices A, B, and D are incorrect because live vaccines are generally contraindicated during pregnancy.

Correct Answer: A

Rationale: The correct answer is A. Paroxetine, an antidepressant commonly used for OCD, typically takes 1 to 4 weeks before the client experiences the full therapeutic benefit. Therefore, informing the client that it may take several weeks before feeling the medication's effects is crucial to manage expectations and ensure compliance with the treatment plan. Choice B is incorrect because Paroxetine is usually taken in the morning due to its activating effects and may cause insomnia if taken before bedtime. Choice C is incorrect because Paroxetine should be taken regularly as prescribed, not just when experiencing obsessive urges. Choice D is incorrect because although weight gain can be a side effect of Paroxetine, it is not a priority instruction compared to the delayed onset of therapeutic effects.
