A nurse is preparing to administer amoxicillin 30 mg/kg/day divided equally every 12 hr to a toddler who weighs 33 lb. Available is amoxicillin 200 mg/5 mL suspension. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["5.625"]
To calculate the dose of amoxicillin for the toddler:
Step 1: Convert the toddler's weight from pounds to kilograms.
33 lb ÷ 2.2 (lb to kg conversion factor) = approximately 15 kg
Step 2: Calculate the total daily dose of amoxicillin.
Dose = 30 mg/kg/day × 15 kg = 450 mg/day
Step 3: Divide the total daily dose into equal doses every 12 hours.
450 mg/day ÷ 2 doses = 225 mg/dose
Step 4: Calculate the amount of amoxicillin suspension needed for each dose.
The available concentration is 200 mg/5 mL, so for 225 mg, you would use the proportion:
225 mg : 200 mg = x mL : 5 mL
Cross-multiplying: x = (225 mg × 5 mL) / 200 mg ≈ 5.625 mL
Therefore, the nurse should administer approximately 5.625 mL of amoxicillin suspension for each dose.

Correct Answer is B
Explanation
A. Dizziness is always a sign of a concussion.
This statement is incorrect. While dizziness can be a symptom of a concussion, it is not always indicative of a concussion. There can be various causes of dizziness, and it is essential to consider other symptoms as well when assessing for a concussion.
B. Bike Helmet Safety
Explanation:
The correct answer to include as part of concussion/head injury prevention teaching to children and parents is "Bike helmet safety." This is because wearing a helmet while riding a bike or participating in other activities that involve head injury risks is crucial to prevent head injuries and concussions. Helmets provide protection to the head by absorbing impact energy and reducing the risk of skull fractures or traumatic brain injuries.
C. Normal fluid intake.
While staying hydrated is important for overall health, it is not directly related to concussion or head injury prevention teaching. This choice is unrelated to the topic.
D. Signs of autism.
Signs of autism are unrelated to concussion or head injury prevention teaching. This choice is not relevant to the topic at hand.
Correct Answer is {"dropdown-group-1":"D"}
Explanation
Pilonidal dimpling with the presence of an abnormal tuft of hair in or near the dimple
Explanation:
Spina bifida is a congenital condition where there is incomplete closing of the backbone and membranes around the spinal cord during early development in the womb. Pilonidal dimpling with the presence of an abnormal tuft of hair in or near the dimple is a specific sign of spina bifida. This condition is called "sacral dimple," and it can indicate an underlying issue with the spinal cord and nerves. An abnormal tuft of hair in or near the dimple suggests a neural tube defect, which is characteristic of spina bifida.
Why the other choices are incorrect:
A. complete paralysis:
Complete paralysis is a severe neurological symptom but it is not specific to spina bifida. It can occur due to various other conditions as well, such as spinal cord injuries, infections, and neurological disorders. It's not a characteristic sign of spina bifida.
B. Petechiae:
Petechiae are small, red or purple spots on the skin that are caused by bleeding under the skin. They are usually associated with bleeding disorders, infections, or other medical conditions. Petechiae are not a characteristic sign of spina bifida.
C. Abnormal Vital Signs:
While spina bifida can potentially lead to neurological complications that might influence vital signs, the presence of abnormal vital signs is a non-specific symptom. Abnormal vital signs could be caused by a wide range of medical conditions, and they are not directly indicative of spina bifida.
