A nurse is obtaining an oxygen saturation on a client.
Which of the following actions should the nurse take?
Relocate the sensor every 8 hrs.
Wait 10 sec after placing the probe before obtaining the oxygen saturation reading.
Choose a finger with a capillary refill less than 2 sec.
Place the sensor probe on the same extremity as an electronic blood pressure cuff.
The Correct Answer is C
Choice A rationale:
Relocating the sensor every 8 hours is not necessary when obtaining oxygen saturation readings unless there is a specific clinical reason to do so, such as skin irritation or poor perfusion at the sensor site. Frequent relocation can cause unnecessary disruption for the patient.
Choice B rationale:
Waiting 10 seconds after placing the probe before obtaining the oxygen saturation reading is not required. Modern pulse oximeters provide real-time readings, and there is no need to wait after placing the probe. The reading is usually stable within seconds.
Choice C rationale:
Choosing a finger with a capillary refill time of less than 2 seconds is an essential consideration when obtaining oxygen saturation readings. Capillary refill time is a measure of peripheral perfusion, and choosing a finger with good perfusion ensures accurate oxygen saturation measurements.
Choice D rationale:
Placing the sensor probe on the same extremity as an electronic blood pressure cuff is generally acceptable. However, it is crucial to ensure that the sensor does not interfere with the blood pressure cuff's function and that it is securely attached to the patient's finger for accurate readings.

Correct Answer is A
Explanation
The correct answer is: a. Remove bibs when the infant is going to sleep.
Choice A reason: Removing bibs when an infant is going to sleep is a critical safety measure to prevent suffocation and strangulation risks. Infants should have a sleep environment free of any loose objects that could cover their face and interfere with breathing. The American Academy of Pediatrics recommends keeping the crib clear of items like bibs, pillows, blankets, and toys to reduce the risk of Sudden Infant Death Syndrome (SIDS) and other sleep-related infant deaths.
Choice B reason: Using a highchair for feedings is not recommended for a 3-month-old infant because they typically cannot sit up unsupported at this age. Highchairs are generally used when an infant can sit up well without support and has good head control, usually around 6 months old. Until then, infants should be held or placed in an appropriate reclined feeding position.
Choice C reason: A soft crib mattress is not advisable for infants. A firm mattress is essential to provide a safe sleep surface. Soft mattresses and other soft surfaces increase the risk of SIDS and suffocation because they can create pockets that may cause an infant’s face to sink in and restrict breathing.
Choice D reason: Placing pillows in the crib, even one small pillow, is unsafe for infants. Pillows can pose a suffocation hazard and increase the risk of SIDS. The crib should be kept bare, with only a firm mattress and a fitted sheet, to ensure a safe sleep environment for the infant.
Correct Answer is B
Explanation
Choice A rationale:
The statement "Avoid breastfeeding for 3 days after receiving the vaccine" is not accurate. Breastfeeding can continue after the MMR vaccination without any adverse effects on the infant. There is no need to interrupt breastfeeding.
Choice B rationale:
The correct instruction is to "Avoid pregnancy for at least 28 days after receiving the vaccine." This is because the MMR vaccine is a live attenuated vaccine, and there is a theoretical risk of transmitting the virus to a developing fetus. Waiting for 28 days after vaccination allows the woman's immune system to respond to the vaccine and reduce any potential risk to the fetus. This is especially important during the postpartum period when a woman may be at risk of becoming pregnant again.
Choice C rationale:
The statement "If you are allergic to gluten, you should not receive this vaccine" is not accurate. The MMR vaccine does not contain gluten as an ingredient. Allergic reactions to the MMR vaccine are generally related to components of the vaccine itself, not gluten.
Choice D rationale:
The instruction to "Your partner should also receive the MMR vaccine" is not a standard recommendation for postpartum women. While it is essential for individuals to be up-to-date on their vaccinations, the focus in this scenario should be on the postpartum woman receiving the MMR vaccine to protect herself and any future pregnancies.
