A nurse is preparing to administer clindamycin 300 mg by intermittent IV bolus over 30 min to a client who has a staphylococcal infection.
Available is clindamycin 900 mg in 50 mL. How many mL/hr should the nurse set the IV pump to? (Round to the nearest whole number, use a leading zero if it applies, do not use a trailing zero)

Full Explanation
Step 1 is to calculate the number of milliliters (mL) that contain the ordered dose of 300 mg of clindamycin.
Step 2 is to divide the total milliliters (mL) from Step 1 by the infusion time in minutes to get the flow rate in mL/hour. Here are the calculations:
Step 1:
900 mg of clindamycin is in 50 mL.
To find the mL that contain 300 mg, set up a proportion:
(300 mg / 900 mg) = (x mL / 50 mL) Cross-multiply and solve for x:
x = (300 mg * 50 mL) / 900 mg x = 16.67 mL
Step 2:
The infusion time is 30 minutes.
Divide the total mL (16.67 mL) by the infusion time in hours to get the flow rate in mL/hour: Flow rate = 16.67 mL / (30 minutes / 60 minutes/hour)
Flow rate = 33.33 mL/hour
Round to the nearest whole number, using a leading zero if it applies, and no trailing zero: Flow rate = 033 mL/hour

A nurse on a medical-surgical unit is planning to delegate tasks to an adult volunteer. Which of the following tasks should the charge nurse avoid assigning to the volunteer?
A. Delivering meal trays to clients in their rooms
Delivering meal trays to clients in their rooms is a simple task that does not require any specialized skills or knowledge. Volunteers can be safely assigned this task, as it does not involve any direct patient care or decision-making.
B. Helping observe postoperative clients who are confused
Observing postoperative clients who are confused requires a higher level of skill and knowledge than delivering meal trays. Volunteers are not typically trained to assess and monitor patients for changes in their condition, and they may not be able to recognize and respond to potential emergencies. This task is best assigned to a licensed nurse or other qualified healthcare professional.
C. Assisting ambulatory clients with meals
Assisting ambulatory clients with meals is another task that can be safely assigned to volunteers. This task involves helping patients with simple activities such as opening food containers and cutting food. Volunteers can be trained to perform these tasks safely and effectively.
D. Delivering mail
Delivering mail is a simple task that does not require any specialized skills or knowledge. Volunteers can be safely assigned this task, as it does not involve any direct patient care or decision-making.

A nurse is assessing a 28-year-old client with HIV who has been admitted with pneumonia. Which of the following observations should the nurse prioritize?
A. Tachypnea and restlessness
Tachypnea and restlessness are common signs of respiratory distress, which is a potential complication of pneumonia. These signs indicate that the client's oxygenation may be compromised and require immediate attention.
B. Weight loss of 1 pound since yesterday
Weight loss of 1 pound since yesterday is a non-specific finding and could be due to a variety of factors, including poor appetite, dehydration, or muscle wasting. While weight loss can be a symptom of HIV infection, it is not an acute sign that requires immediate prioritization in this case.
C. Frequent loose stools
Frequent loose stools can be a symptom of HIV infection or a side effect of certain medications. However, it is not an acute sign that requires immediate prioritization in this case, especially in the context of the client's respiratory distress.
D. Oral temperature of 100°F
An oral temperature of 100°F is a low-grade fever and is not a specific indicator of any serious condition. While fever can be a symptom of pneumonia, it is not the most concerning finding in this case. Therefore, based on the client's presenting symptoms, tachypnea and restlessness are the most concerning findings and should be prioritized by the nurse.

A nurse is performing discharge teaching for a client who has seizures and a new prescription for phenytoin.
Which of the following statements by the client indicates a need for further teaching?
A. “I’ll be glad when I can stop taking this medication.”
Phenytoin is an anticonvulsant medication used to control seizures. It is typically a long-term medication, and abruptly stopping it can lead to breakthrough seizures or worsen existing seizures. This statement indicates that the client may not understand the importance of taking phenytoin consistently and the potential consequences of discontinuing it without consulting their doctor.
B. “I have made an appointment to see my dentist next week.”
Making an appointment with a dentist is important for all individuals, including those with seizure disorders. There is no specific concern related to phenytoin and dental care that would necessitate further teaching in this context.
C. “I know that I cannot switch brands of this medication.”
It is important for clients to understand that switching brands of phenytoin might affect its effectiveness due to slight variations in formulation. However, simply stating awareness of this fact does not necessarily indicate a need for further teaching, as the nurse can assess the client's understanding through further questioning.
D. "I will notify my doctor before starting this medication"
Notifying a doctor before taking any new medications is crucial for individuals with seizures, as some medications can interact with phenytoin and increase the risk of seizures. This statement demonstrates the client's understanding of an important safety precaution.

Therefore, Choice A is the only statement that suggests a potential lack of understanding about the long-term nature of phenytoin treatment and the dangers of discontinuing it without medical supervision. This highlights the need for further education to ensure the client's safety and adherence to the prescribed medication regimen.
