Specimen Collection Flashcards
After bacteria are cultured from a midstream urine specimen, what is accomplished by sensitivity testing?
A. Confirms the accuracy of the results of the culture
B. Identifies the immune system’s reaction to the presence of the bacteria
C. Determines whether the patient is allergic to the antibiotic agent with which the provider plans to treat the infection
D. Determines which antibiotic agent is most effective in killing the bacteria
D. Sensitivity testing of a bacterial culture determines which antibiotic the bacteria are most vulnerable (sensitive) to and therefore which agent is likely to be the most effective in killing them.
What can the nurse do to help ensure an accurate result when collecting a midstream urine sample for a patient who is menstruating?
A. Notify the health care provider.
B. Make a note on the lab slip that the patient is menstruating.
C. Postpone the specimen collection until menses has ceased.
D. Do nothing other than follow normal procedure, since menstruation will not affect the results.
B.The nurse would make a note on the lab slip that the patient is menstruating, to alert the lab to the possible source of any blood detected in the specimen.
Which statement might the nurse make to nursing assistive personnel (NAP) assigned to collect a midstream urine specimen from a patient with signs of a urinary tract infection?
A. “Obtain 30 to 60 mL of midstream urine.”
B. “The urine has a foul odor.”
C. “Teach the patient to collect the urine specimen.”
D. “Be sure to maintain aseptic technique.”
D.
Which statement might the nurse make to nursing assistive personnel (NAP) in order to help ensure reliable results of culture and sensitivity testing of a midstream urine specimen?
A. B.“I’ll need a biohazard bag to put the specimen into.”
B. “Please get the specimen to the lab within 20 minutes.”
C. “After you replace the cap, please wipe any drops of urine from the outside of the container.”
D. “We are out of specimen collection kits.”
B. The nurse is likely to give this instruction to the NAP, because the specimen must be delivered to the lab within 20 minutes of collection. Doing so ensures that the reliability of the specimen is not compromised.
hat is the most important action the nurse can take to ensure that a midstream urine specimen does not become contaminated?
A. Wear sterile gloves to open the sterile specimen kit.
B. Ensure that the patient’s perineum has been cleansed before the specimen is obtained.
C. Determine if the patient has any known allergies.
D. Have the patient rate his or her current pain level.
B.
What is the initial step in preparing a fecal occult blood test?
A. Determine the patient’s ability to help obtain a sample.
B. Gather both a Hemoccult slide and developing solution.
C. Remind the patient that we test one section of the bowel movement.
D. Use Gastroccult developer with Hemoccult developer.
A.
The nurse has delegated to nursing assistive personnel (NAP) the task of performing fecal occult blood tests on the stool of a patient with a history of positive results. Which instruction is most relevant to performing this test in this particular patient?
A. “Notify me only if the test is positive.”
B. “Save the stool sample so that I can retest it if it is positive.”
C. Remind the patient that we test one section of the bowel movement.
D. Use Gastroccult developer with Hemoccult developer.
B.The nurse is likely to give NAP this instruction, because any sample from which NAP obtains a positive result must be retested.
Which instruction to nursing assistive personnel (NAP) is most relevant to the proper performance of a fecal occult blood test using a Hemoccult slide?
A. “Be sure to wear sterile gloves.”
B. “Reinforce with the patient the need to use the hat.”
C. “Is the patient capable of assisting with the collection?”
D. “Remember to take samples from two different areas of the specimen.”
D.This is the most relevant instruction, because stool samples must be taken from two different areas and placed on the slide.
Which statement indicates proper interpretation of the results of a positive fecal occult blood test?
A. “If the sample turns blue, it is positive for bleeding.”
B. “The sample turned blue after about 45 seconds.”
C. “The results were positive both times the sample was tested.”
D. “Because it was positive, the patient must be asked when he or she last ate red meat.”
D.This statement indicates the nurse’s awareness that a positive result does not necessarily indicate gastrointestinal bleeding.
Which of the following nursing actions addresses the risk for infection related to fecal occult blood testing?
A. Maintaining aseptic technique while performing the test
B. Performing the fecal occult blood testing in the patient’s bathroom
C. Wearing clean gloves while testing
D. Assessing the patient’s ability to provide an uncontaminated fecal specimen
C.
