A nurse is reviewing the laboratory reports of four clients.
Which of the following clients should the nurse expect to have a positive fecal occult blood test?
A client who has ulcerative colitis.
A client who has cholecystitis.
A client who uses laxatives.
A client who has stomatitis.
The Correct Answer is A
Choice A rationale
Ulcerative colitis often results in inflammation and ulcers in the colon lining, which can lead to bleeding and a positive fecal occult blood test. This is a common complication of the condition.
Choice B rationale
Cholecystitis, an inflammation of the gallbladder, does not typically cause gastrointestinal bleeding or a positive fecal occult blood test. It is more associated with abdominal pain and digestive issues.
Choice C rationale
The use of laxatives generally does not cause internal bleeding that would result in a positive fecal occult blood test. Laxatives are more likely to cause changes in bowel habits and diarrhea.
Choice D rationale
Stomatitis, inflammation of the mouth, is unlikely to cause a positive fecal occult blood test. It primarily affects the oral cavity and is not associated with gastrointestinal bleeding. .

Correct Answer is C
Explanation
Choice A rationale
Placing the specimen in a clean specimen cup is not appropriate for a urine culture and sensitivity test. A sterile specimen cup is required to avoid contamination and ensure accurate results.
Choice B rationale
Removing 45 mL of urine from the catheter with a syringe is incorrect. Only 5-10 mL of urine is needed for a culture and sensitivity test, and excessive removal can lead to inaccurate test results or sample contamination.
Choice C rationale
Clamping the catheter tubing below the needleless port is the correct action. This allows urine to accumulate in the tubing, providing a fresh and uncontaminated sample for the culture and sensitivity test.
Choice D rationale
Clamping the catheter tubing for 60 minutes is too long and can cause urine stasis, increasing the risk of catheter-associated urinary tract infections. The tubing should be clamped only for a short duration to collect an adequate sample. .
Correct Answer is D
Explanation
Choice A rationale
While checking recent medication administration is important, it is not the immediate priority when a client is experiencing shortness of breath. Immediate actions should focus on assessing and improving the client's oxygenation status.
Choice B rationale
Reviewing the client’s most recent SaO2 level is useful, but not the first action to take when there is an immediate concern for the client’s oxygenation. Addressing the current low SaO2 level takes precedence.
Choice C rationale
Notifying the charge nurse is necessary, but the nurse should first attempt to quickly re-evaluate the client’s condition and try simple interventions to improve oxygenation, such as having the client cough and clear their throat.
Choice D rationale
Rechecking the SaO2 level after having the client cough and clear their throat is the appropriate first action. This can help determine if the low SaO2 reading is due to a temporary obstruction, such as mucus, and allows for a more accurate assessment of the client's respiratory status. .
