A nurse is planning to obtain a client's oxygen saturation. Which of the following might influence the result of this test?
The client is wearing nail polish.
The client has an elevated hemoglobin level.
The client has a fever.
The client is wearing a ring.
The Correct Answer is A
A. Nail polish can interfere with the accuracy of pulse oximetry readings by absorbing or
reflecting light, leading to falsely low oxygen saturation readings. It's essential to remove nail polish or acrylic nails from the finger used for pulse oximetry to obtain accurate results.
B. While an elevated hemoglobin level may affect the oxygen-carrying capacity of the blood, it does not directly influence the accuracy of pulse oximetry readings.
C. Fever may affect oxygen saturation levels indirectly by increasing metabolic demand or
respiratory rate, but it does not directly interfere with the accuracy of pulse oximetry readings.
D. Wearing a ring does not typically interfere with pulse oximetry readings unless the ring is very tight and impairs blood flow to the finger. However, nail polish is a more significant
concern for accurate readings.

Correct Answer is D
Explanation
A. Napping during the day may disrupt nighttime sleep patterns by reducing sleep drive.
B. Watching television in bed can stimulate the brain and interfere with sleep due to the blue light emitted from screens.
C. Engaging in vigorous physical activity close to bedtime may increase alertness and make it harder to fall asleep.
D. Drinking a glass of milk before bedtime can promote sleep due to the presence of tryptophan, which aids in the production of serotonin and melatonin, neurotransmitters involved in sleep
regulation.
Correct Answer is C
Explanation
A. This technique is used for children, not adults. To straighten the ear canal for adults, the pinna should be pulled upwards and back.
B. Cleansing the outer ear with isopropyl alcohol is not typically necessary before administering otic medication and may cause irritation to the delicate skin of the ear canal.
C. Holding the dropper 1 cm away allows for better control and accuracy when directing the medication droplets into the ear canal. This helps ensure the medication reaches the intended area within the middle ear. Holding the dropper too close could accidentally touch the ear canal or eardrum, causing discomfort or even injury. Maintaining a slight distance helps prevent the dropper tip from contaminating the ear canal with skin flora from the client or the nurse's hand.
D. While some otic medications might recommend staying still for a short time after administration, 10 minutes is an excessive timeframe for most medications.
