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.

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.

Correct Answer: A

Rationale: The correct instruction for the nurse to include when teaching a client with OCD who has a new prescription for Paroxetine is that it can take several weeks before the client feels like the medication is helping. Paroxetine, like other selective serotonin reuptake inhibitors (SSRIs), can take 1 to 4 weeks before the client reaches the full therapeutic benefit. Therefore, it is important to inform the client about this delay in onset of action to manage their expectations and promote adherence to the treatment plan. Choices B, C, and D are incorrect because taking Paroxetine before bedtime is not necessary, it should be taken consistently at the same time each day; Paroxetine is usually taken regularly, not as needed; and while monitoring weight is important, it is not a specific instruction related to the onset of action for Paroxetine.

Correct Answer: D

Rationale: The correct answer is to advise the client to limit aerobic activity in hot weather. Aerobic activity in hot weather can lead to excessive sweating, potentially causing sodium and water depletion, which can increase the risk of Lithium toxicity. It is important for clients taking Lithium to maintain adequate hydration and sodium levels to prevent toxicity. Choices A, B, and C are incorrect. Avoiding acetaminophen for headaches is not directly related to Lithium toxicity. Restricting intake of foods rich in sodium is not recommended because adequate sodium levels are necessary to prevent Lithium toxicity. Decreasing fluid intake to less than 1,500 mL daily is also not advisable as adequate hydration is important to prevent Lithium toxicity.

Correct Answer: B

Rationale: The correct answer is B: 'Notify the provider if you develop breast enlargement.' Gynecomastia (breast enlargement) and galactorrhea can occur due to an increase in prolactin levels while taking risperidone. The client should inform the provider if these manifestations occur. Choices A, C, and D are incorrect. Adding extra snacks to the diet to prevent weight loss is not a specific instruction related to risperidone. Seizures are not a common side effect of risperidone, so the statement about mild seizures is inaccurate. Risperidone is more likely to cause sexual side effects like erectile dysfunction rather than increasing libido, making choice D incorrect.
