A nurse is planning to collect a stool specimen from an infant to check for the presence of ova and parasites. Which of the following actions should the nurse plan to take?
Obtain the specimen by swabbing the infant's rectum using a sterile culture swab.
Place a urine collection device on the infant until the specimen is obtained.
Transfer the specimen to the collection container using povidone-iodine-soaked gauze.
Maintain the specimen at room temperature after collection until it is transferred to the lab.
The Correct Answer is A
Choice A rationale:
Obtain the specimen by swabbing the infant's rectum using a sterile culture swab. This is the correct choice. When collecting a stool specimen from an infant, the rectal swab method is commonly used. A sterile culture swab helps prevent contamination and ensures accurate results for detecting the presence of ova and parasites in the stool.
Choice B rationale:
Place a urine collection device on the infant until the specimen is obtained. This choice is not appropriate for collecting a stool specimen. A urine collection device is used for collecting urine, not stool. The specimen for ova and parasites needs to be taken directly from the rectum or diaper to accurately identify any infestations.
Choice C rationale:
Transfer the specimen to the collection container using povidone-iodine-soaked gauze. While povidone-iodine is an antiseptic, it is not typically used to transfer stool specimens. Using a sterile swab or a clean, dry container is more suitable for collecting and transporting stool samples to the lab.
Choice D rationale:
Maintain the specimen at room temperature after collection until it is transferred to the lab. Stool specimens for ova and parasites usually require refrigeration to prevent the degradation and growth of potential pathogens. Room temperature might lead to the overgrowth of bacteria and parasites, affecting the accuracy of test results.

Correct Answer is B
Explanation
Answer: B. Reposition the probe every 2 hours.
Rationale:
- A. Warm the skin prior to probe placement:While cold fingers can lead to inaccurate readings,warming the skin is not an essential step and is not routinely recommended in clinical practice.
- B. Reposition the probe every 2 hours:This iscorrect.Continuous pressure from the probe in one spot can cause skin breakdown and pressure injuries.Repositioning the probe every 2 hours helps to prevent this and ensure accurate readings.
- C. Tape the wire to the palm of the hand:This is incorrect.The pulse oximeter probe should be placed on a vascular site,such as a fingertip or earlobe.Taping the wire to the palm would not provide accurate readings.
- D. Apply the sensor to the index fingernail:This is incorrect.The fingernail does not have sufficient blood flow for accurate pulse oximetry readings.The probe should be placed on the fleshy pad of the fingertip.
Therefore, the most important action for the nurse to take is to reposition the probe every 2 hours to prevent skin breakdown and ensure accurate readings.
Additional Points:
- The nurse should also choose a clean and dry site for probe placement.
- The probe should be snug but not too tight.
- The nurse should monitor the child for signs of skin breakdown,such as redness,swelling,or pain.
- If the child is restless or active,the nurse may need to secure the probe with additional tape or a special wrap.
Correct Answer is C
Explanation
Choice A rationale:
This medication can cause ringing in the ears (Choice A) is not a common side effect of amoxicillin. Ringing in the ears (tinnitus) is not typically associated with the use of this antibiotic.
Choice B rationale:
This medication can cause muscle pain (Choice B) is not a common side effect of amoxicillin. Muscle pain is not among the usual adverse reactions associated with its use.
Choice C rationale:
This medication can cause loose stools (Choice C) is a relevant side effect of amoxicillin. Antibiotics, including amoxicillin, can disrupt the normal balance of gut bacteria, potentially leading to gastrointestinal disturbances such as diarrhea or loose stools.
Choice D rationale:
This medication can cause blurred vision (Choice D) is not a common side effect of amoxicillin. Blurred vision is not a typical adverse effect associated with the use of this antibiotic.
