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
A) Incorrect- The left lateral position might not provide enough lung expansion for a client in respiratory distress.
B) Incorrect- Reverse Trendelenburg (head of bed elevated, foot of bed lowered) might not provide enough lung expansion and could exacerbate respiratory distress.
C) Correct- The High-Fowler's position, where the client is sitting upright at a 90-degree angle or as upright as tolerated, helps to improve lung expansion, reduce pressure on the diaphragm, and promote optimal oxygenation. This position is commonly used for clients with respiratory distress.
D) Incorrect- The supine position may worsen pulmonary congestion and compromise lung expansion in clients with pulmonary edema.
Correct Answer is ["B","C","D","G","H"]
Explanation
- Capillary refill: This is a quick and simple way to assess the adequacy of peripheral perfusion and can help identify signs of dehydration.
- Skin turgor: Assessing the skin turgor, or the elasticity of the skin, is another useful indicator of dehydration.
- Heart rate: Tachycardia can be a sign of dehydration, so monitoring the heart rate is an important component of the assessment.
- Blood pressure: Blood pressure can be affected by dehydration, so monitoring it is important in determining the severity of dehydration and in guiding appropriate interventions.
- Temperature: Fever is a potential cause of dehydration, so monitoring the temperature is an important part of the assessment.
- Skin color of hands and feet: Checking the color of the skin on the hands and feet can help identify signs of poor perfusion and dehydration.
Assessing the level of consciousness, pupil size and reactiveness, and respiratory rate are important aspects of the neurological and respiratory assessments but are not specific to the assessment of dehydration.
