A provider orders a diagnostic test for a client with a urinary tract infection. The test will determine the strain of bacteria causing the infection and determine the antibiotic that will treat the infection. The nurse knows this test is called which of the following?
urine culture and sensitivity
serum creatinine level
urinalysis
kidney scan
The Correct Answer is A
A. Urine culture and sensitivity
Explanation: A urine culture and sensitivity test involves growing bacteria from a urine sample in a laboratory setting. Once the bacteria have grown, they are exposed to different antibiotics to see which one is most effective in inhibiting their growth. This helps healthcare providers identify the specific strain of bacteria causing the infection and choose the most appropriate antibiotic treatment.
B. Serum creatinine level
Explanation: Serum creatinine level is a blood test used to measure kidney function. It evaluates how well the kidneys are filtering waste from the blood. While important for assessing kidney health, it does not determine the specific bacteria causing a urinary tract infection or the appropriate antibiotic treatment.
C. Urinalysis
Explanation: Urinalysis is a broad screening test that assesses various components in the urine, such as red and white blood cells, protein, glucose, and bacteria. While it can detect signs of a urinary tract infection (such as the presence of bacteria and white blood cells), it does not identify the specific bacterial strain causing the infection or provide information about antibiotic sensitivity.
D. Kidney scan
Explanation: A kidney scan, also known as a renal scan, is a medical imaging technique used to assess the structure and function of the kidneys. It can help diagnose conditions like kidney stones, urinary obstruction, or kidney infections. However, it does not determine the strain of bacteria causing a urinary tract infection or guide antibiotic treatment.

Correct Answer is ["250"]
Explanation
To calculate the infusion rate, you first need to determine the total volume to be infused and the total time over which the infusion will occur.
Three 1L bags need to be infused over 12 hours.
Total volume = 3 bags * 1000 mL/bag = 3000 mL
Total time = 12 hours
Now, to find the rate in milliliters per hour (mL/h), divide the total volume by the total time:
Infusion rate = Total volume / Total time
Infusion rate = 3000 mL / 12 hours = 250 mL/h
Correct Answer is A
Explanation
A. Sedentary lifestyle - Lack of weight-bearing exercise and physical activity is a significant risk factor for the development of osteoporosis. Weight-bearing exercises help maintain bone density and strength. Sedentary individuals are more prone to osteoporosis.
B. Long-term use of diuretics - Long-term use of certain medications, such as corticosteroids, can increase the risk of osteoporosis. Diuretics are not typically associated with osteoporosis risk, although some medications can affect bone health.
C. Prolonged stress - Chronic stress can have negative effects on overall health, but it is not a direct risk factor for osteoporosis.
D. Obesity - Obesity is generally considered a protective factor against osteoporosis. Individuals with higher body weight tend to have stronger bones due to the mechanical load placed on the bones, reducing the risk of osteoporosis.
