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)
The Correct Answer is ["033"]
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

Correct Answer is A
Explanation
Choice A rationale:
Fever is the most reliable early indicator of infection in a client with low WBC because it is a direct physiologic response to the presence of pathogens. When the body detects an infection, it releases pyrogens, which act on the hypothalamus to raise the body's temperature. This elevated temperature helps to create an environment that is less hospitable to bacteria and viruses, and it also stimulates the immune system to fight the infection.
In clients with low WBC, the immune system is already compromised, so the fever response may be even more pronounced. It's important to note that even a slight elevation in temperature (as low as 100.4°F or 38°C) can be significant in these clients.
Choice B rationale:
Chills can also be a sign of infection, but they are not as specific as fever. Chills can occur for other reasons, such as exposure to cold or anxiety.
Choice C rationale:
Tachycardia, or increased heart rate, can also be a sign of infection, but it is not as reliable as fever. Tachycardia can occur for other reasons, such as dehydration, pain, or anxiety.
Choice D rationale:
Dyspnea, or shortness of breath, is not a typical early sign of infection. It is more likely to occur in later stages of infection, when the infection has spread to the lungs.
Correct Answer is C
Explanation
Choice A rationale:
A high-purine diet is not recommended for clients with gout. Purines are substances found in certain foods, such as red meat, organ meats, seafood, and beer. When the body breaks down purines, it produces uric acid. Uric acid is a waste product that can build up in the blood and cause gout attacks.
Choice B rationale:
Aspirin is not typically recommended for clients with gout. In fact, aspirin can sometimes worsen gout symptoms by increasing uric acid levels in the blood.
Choice C rationale:
Limiting alcohol intake is a key part of the treatment regimen for gout. Alcohol can increase uric acid levels in the blood and trigger gout attacks.
Choice D rationale:
Limiting fluid intake is not recommended for clients with gout. In fact, it is important for clients with gout to stay well- hydrated to help flush uric acid out of the body.
