1. Which of the following is considered a class IA Sodium Channel blocker?

Correct answer: D

Rationale: Procainamide is a class IA antiarrhythmic drug that acts as a sodium channel blocker by blocking fast sodium channels. Mexiletine is a class IB antiarrhythmic drug, not class IA. Amiodarone is a class III antiarrhythmic, and Quinidine is a class IA antiarrhythmic but not a sodium channel blocker.

2. A client has a new prescription for Lisinopril. Which of the following laboratory values should be monitored?

Correct answer: A

Rationale: Corrected Rationale: Lisinopril is an ACE inhibitor that can cause hyperkalemia by reducing potassium excretion through the kidneys. Monitoring serum potassium levels is crucial to detect hyperkalemia early and prevent adverse effects such as cardiac arrhythmias. Choices B, C, and D are incorrect because Lisinopril is not known to significantly impact sodium, calcium, or magnesium levels in the same way it affects potassium levels.

3. A child is prescribed Amoxicillin 20 mg/kg/day PO to be administered every 12 hr. The child weighs 44 lb. The available medication is amoxicillin suspension 250 mg/5 mL. How many mL should be given per dose?

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.

4. A client has a new prescription for Zolpidem. Which of the following instructions should the nurse include?

Correct answer: A

Rationale: Zolpidem is classified as Pregnancy Risk Category C. It is important for the client to inform the provider if they plan to become pregnant because the medication may need to be adjusted or changed to ensure the safety of the fetus. This communication allows for appropriate monitoring and adjustments to be made to the treatment plan. Choice B is incorrect because zolpidem should be taken just before going to bed, not specifically 1 hour before. Choice C is incorrect as zolpidem is a short-acting medication, and it does not require a full 6 hours for sleep. Choice D is incorrect because zolpidem can be taken with or without food, so taking it with a bedtime snack is not contraindicated.

5. A client in labor is receiving IV Opioid analgesics. Which of the following actions should the nurse take?

Correct answer: B

Rationale: Offering oral hygiene every 2 hours is essential for a client receiving opioid analgesics to prevent dry mouth, nausea, and vomiting, which are common adverse effects associated with opioid use. This intervention promotes comfort and enhances the client's well-being during labor. Instructing the client to self-ambulate every 2 hours is not appropriate for a client in labor receiving opioid analgesics, as it may be challenging and unnecessary during this time. Anticipating medication administration 2 hours prior to delivery is not necessary as the timing of medication administration should be based on the client's pain level and the duration of action of the opioid. Monitoring fetal heart rate every 2 hours is important during labor, but the priority in this case is to address the client's comfort and well-being by offering oral hygiene.
