An infant who weighs 22 pounds receives a prescription for amoxicillin 20 mg/kg/day by mouth in divided doses every 8 hours. The bottle is labeled, "Amoxicillin for Oral Suspension, USP 250 mg per 5 mL." How many mL should the nurse administer with each dose? (Enter numerical value only. If rounding is necessary, round to the nearest tenth.)
The Correct Answer is ["1.3"]
1. Convert the infant's weight from pounds to kilograms. We can use the conversion factor 1 kg
= 2.2 lb. So, 22 lb x (1 kg / 2.2 lb) = 10 kg.
2. Calculate the total daily dose of amoxicillin for the infant. We can use the formula D = d x W, where D is the total daily dose, d is the dose per kg per day, and W is the weight in kg. So, D = 20 mg x 10 kg = 200 mg.
3. Calculate the single dose of amoxicillin for the infant. We can divide the total daily dose by the number of doses per day. Since the prescription is for every 8 hours, there are 3 doses per day. So, 200 mg / 3 = 66.67 mg.
4. Calculate the volume of amoxicillin suspension for the single dose. We can use the ratio of the concentration of the suspension, which is 250 mg per 5 mL. So, 66.67 mg x (5 mL / 250 mg) =
1.33 mL.
5. Round the volume to the nearest tenth= 1.3 mL

Correct Answer is C
Explanation
The correct answer is: C. Experiences facial swelling after eating crab.
Choice A Reason: Drinking a glass of water in the past 2 hours is not typically a concern unless the patient has been instructed to fast. For most cardiac catheterization procedures, patients are asked to fast for a certain period before the procedure to reduce the risk of aspiration. However, small sips of water may be allowed with medications.
Choice B Reason: While reports of left chest wall pain are clinically significant and warrant investigation, they are not as immediately concerning for the angioplasty procedure itself. Chest pain is a symptom that may have led to the decision to perform angioplasty but does not pose an immediate risk of complication during the procedure as an allergy might.
Choice C Reason: As previously mentioned, experiencing facial swelling after eating crab is indicative of a shellfish allergy. This is important because the contrast dye used in angioplasty may contain iodine, and patients with shellfish allergies could have an increased risk of an allergic reaction to the iodine in the dye. It is essential to explore this further to take necessary precautions, such as premedication with antihistamines or using a different contrast agent.
Choice D Reason: Verbalizing a fear of being in a confined space, or claustrophobia, is a psychological concern that should be addressed to ensure the patient’s comfort during the procedure. However, it does not pose a direct risk to the safety of the angioplasty procedure like an allergic reaction does. Managing patient anxiety is important, but it is not the most critical factor to explore prior to the procedure.
Correct Answer is B
Explanation
The client is experiencing severe abdominal incisional pain, and her vital signs indicate an elevated heart rate, respiratory rate, and blood pressure. These signs suggest that the client is in distress and may be experiencing pain-related complications.
Assessing the IV site for patency is crucial to ensure that the client is receiving the prescribed IV analgesic medication effectively. If the IV site is not patent or if there is any obstruction, the administration of IV analgesics may be delayed, resulting in inadequate pain relief for the client.
While providing a pillow for splinting can offer comfort and support to the client, it is not the most critical intervention in this situation. Placing the client in a high Fowler position may help with pain management, but it is not the priority at this moment. Administering an IV analgesic is an appropriate intervention, but before doing so, it is essential to ensure that the IV site is patent.
