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
Delegation involves assigning tasks to individuals who have the appropriate skills and competence to perform them safely and effectively. Inserting urinary catheters for uncomplicated clients is a task that can be delegated to a practical nurse. It is a common procedure within the scope of practice for a practical nurse, and it does not require the level of assessment and critical thinking involved in evaluating and updating plans of care or receiving a postoperative client and conducting an assessment.
Verifying the readiness of clients for discharge typically involves comprehensive assessments, coordination with other healthcare professionals, and decision-making regarding the appropriateness of discharge. This task is generally performed by registered nurses (RNs) or other members of the healthcare team with advanced training.
Evaluating and updating plans of care for clients is a responsibility that falls within the scope of practice of registered nurses. It requires a higher level of assessment, clinical judgment, and decision-making, which are typically beyond the scope of practice of a practical nurse.
Receiving a postoperative client and conducting the assessment involves comprehensive assessment skills and critical thinking, which are typically within the scope of practice of a registered nurse or an advanced practice nurse.
Correct Answer is C
Explanation
A) Incorrect- Clarify reality with the client about delusional thoughts: Attempting to correct the client's delusional thoughts might cause frustration and agitation. Clients with Alzheimer's disease may have difficulty comprehending and retaining reality-based information.
B) Incorrect- Reduce the client's interaction with others during the day: Social interaction is important for clients with Alzheimer's disease to maintain engagement and prevent feelings of isolation. Reducing interaction could worsen their emotional well-being.
C) Correct- Clients with Alzheimer's disease often experience cognitive impairments and may have delusional thoughts or confusion, such as believing deceased loved ones are still alive. Nonpharmacological interventions are crucial to provide comfort and manage challenging behaviors. Distraction techniques involve redirecting the client's attention away from the delusion and onto a different, engaging activity. This can help decrease distress and anxiety related to their delusional thoughts. Therapeutic communication skills, such as validating the client's feelings and emotions, can also be beneficial. Simply telling the client that their mother is deceased may cause distress and confusion. Instead, providing comfort, empathizing with their emotions, and redirecting their focus can be more effective in managing the situation.
D) Incorrect- Awaken the client for reality checks every 4 hours at night: Disrupting the client's sleep schedule could lead to increased confusion and restlessness. It's important to provide a calm and consistent sleep routine for individuals with Alzheimer's disease.
