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.)

Full Explanation
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.

A nurse is caring for a client who is to receive liquid medications via a gastrostomy tube. The client is prescribed phenytoin 250 mg. The amount available is phenytoin oral solution 25 mg/5 mL. How many mL should the nurse administer per dose?
(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Full Explanation
To calculate the mL of phenytoin oral solution needed for a 250 mg dose, we can use the following equation:
Dose (mg) = Volume (mL) × Concentration (mg/mL)
Given:
Dose = 250 mg
Concentration = 25 mg/5 mL
We need to find the volume (mL):
Volume (mL) = Dose (mg) / Concentration (mg/mL)
Volume (mL) = 250 mg / (25 mg/5 mL)
Volume (mL) = 250 mg / (5 mg/mL)
Volume (mL) = 50 mL
So, the nurse should administer 50 mL of phenytoin oral solution per dose.
A nurse is caring for a child who is having a seizure. Which of the following actions should the nurse take? (Select all that apply.)
A. Place a tongue depressor in the client's mouth.
Place a tongue depressor in the client's mouth:Placing a tongue depressor in the client's mouth is not recommended during a seizure. Doing so can lead to injury, as the child may bite down on the depressor and cause harm to their teeth or mouth.
B. Restrain the client.
Restrain the client:Restraining a person during a seizure can be extremely dangerous. It can lead to physical harm to both the person experiencing the seizure and the person trying to restrain them. Restraining can increase the risk of fractures, dislocations, and other injuries.
C. Assess the client's airway palenty
Assess the client's airway patency:Assessing the client's airway patency is essential during a seizure. The nurse should ensure that the child's airway is clear and open to maintain proper breathing. This involves observing for any obstruction or difficulty in breathing and taking appropriate measures to keep the airway open.
D. Remove objects from the client's bed
Remove objects from the client's bed: Removing objects from the client's bed is a necessary action to prevent injury during a seizure. Objects on the bed can pose a risk of harm to the child if they were to strike them during the seizure. Creating a safe environment by removing potential hazards is important.
E. Place the client in a side-lying position
Placing the client in a side-lying position is recommended during a seizure. This position helps prevent aspiration and maintains a clear airway. It also reduces the risk of choking and allows any fluids to drain from the mouth, minimizing the risk of choking.
Full Explanation
A) Place a tongue depressor in the client's mouth:
Incorrect. Placing a tongue depressor in the client's mouth is not recommended during a seizure. Doing so can lead to injury, as the child may bite down on the depressor and cause harm to their teeth or mouth.
B) Restrain the client:
Incorrect. Restraining a person during a seizure can be extremely dangerous. It can lead to physical harm to both the person experiencing the seizure and the person trying to restrain them. Restraining can increase the risk of fractures, dislocations, and other injuries.
C) Assess the client's airway patency:
Correct. Assessing the client's airway patency is essential during a seizure. The nurse should ensure that the child's airway is clear and open to maintain proper breathing. This involves observing for any obstruction or difficulty in breathing and taking appropriate measures to keep the airway open.
D) Remove objects from the client's bed:
Correct. Removing objects from the client's bed is a necessary action to prevent injury during a seizure. Objects on the bed can pose a risk of harm to the child if they were to strike them during the seizure. Creating a safe environment by removing potential hazards is important.
E) Place the client in a side-lying position:
Correct. Placing the client in a side-lying position is recommended during a seizure. This position helps prevent aspiration and maintains a clear airway. It also reduces the risk of choking and allows any fluids to drain from the mouth, minimizing the risk of choking.
In summary:
Choice A is incorrect because placing a tongue depressor can cause injury.
Choice B is incorrect because restraining can lead to harm.
Choice C is correct because assessing the airway ensures proper breathing.
Choice D is correct because removing objects reduces the risk of injury.
Choice E is correct because placing the client in a side-lying position helps maintain a clear airway and prevents aspiration.
We know that reflux refers to the retrograde flow of bladder urine into the ureters, which of the following items are important information in the patient’s history? (Select All that Apply)
A. The fact that the patient is male
The fact that the patient is male: The patient's gender does not directly provide important information about the history of reflux.Explanation: Vesicoureteral reflux (VUR), which is the retrograde flow of urine from the bladder into the ureters, can affect individuals of any gender. While gender might have some implications for certain conditions, it is not a critical factor in understanding the history of reflux.
B. The fact that the patient is female.
The fact that the patient is female.The patient's gender does not directly provide important information about the history of reflux.Explanation: Just like with the previous option, the patient's gender does not play a significant role in the history of vesicoureteral reflux. The condition can affect both males and females.
C. Developmental milestones
Developmental milestones: Developmental milestones are important in understanding the history of reflux.Explanation: Developmental milestones are significant because VUR is more common in infants and young children. Infants and young children have a higher likelihood of developing reflux due to the immaturity of their urinary tract systems. Knowing about the patient's developmental milestones can help assess the risk and potential severity of reflux.
D. The number of urinary tract infections the patient has had
The number of urinary tract infections the patient has had: The number of urinary tract infections (UTIs) is important in understanding the history of reflux.Explanation: Repeated urinary tract infections can be a sign of vesicoureteral reflux. The backflow of urine from the bladder into the ureters can contribute to UTIs. Monitoring the frequency of UTIs can provide insights into the presence and severity of reflux.
