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 C
Explanation
Choice A rationale:
A high-purine diet is actually contraindicated in gout because purines are metabolized into uric acid, which can accumulate in the joints and trigger gout attacks. Therefore, a low-purine diet is recommended.
Choice B rationale:
Aspirin is not typically recommended for gout because it can interfere with the excretion of uric acid and potentially worsen the condition. While low-dose aspirin might be used for specific cardiovascular benefits in some gout patients, it's not a general treatment for gout itself.
Choice C rationale:Alcohol intake is a common trigger for gout attacks because it can increase uric acid levels in the blood. Therefore, limiting alcohol intake is an important part of managing gout.
Choice D rationale:
Fluid intake should be increased, not limited, in gout patients. This is because adequate hydration helps to flush uric acid out of the body and reduce the risk of gout attacks.
Correct Answer is A
Explanation
Choice A rationale:
Lymph nodes are small, bean-shaped structures that play a crucial role in the immune system. They filter lymph fluid, which carries white blood cells and other immune cells throughout the body.
When the body is fighting an infection or other immune challenge, lymph nodes often swell and become tender. This is because they are actively working to filter out pathogens and activate immune cells.
Palpation of the lymph nodes can provide valuable information about the patient's immune function. The nurse can assess for enlargement, tenderness, and mobility of the lymph nodes.
Lymph node assessment is a non-invasive, painless procedure that can be performed quickly and easily.
Choice B rationale:
Auscultation of the apical heart rate is important for assessing cardiovascular function, but it does not directly assess immune function.
While heart rate can be indirectly affected by certain immune conditions (e.g., fever), it is not a primary indicator of immune system activity.
Choice C rationale:
Palpation of the liver can provide information about liver size and consistency, but it does not directly assess immune function.
The liver plays a role in immune function by producing proteins that help fight infection, but its size and consistency do not necessarily reflect its immune activity.
Choice D rationale:
Percussion of the abdomen can be used to assess the size and location of abdominal organs, but it does not directly assess immune function.
While certain immune conditions may involve abdominal organs (e.g., splenomegaly), percussion is not a primary method for assessing immune function.
