A nurse is preparing to perform hand hygiene. Which action should the nurse take for hand hygiene to be effective?
Rub soap on hands for 20 seconds.
Allow hands and arms to dry.
Hold the hands higher than the elbows.
Adjust the water temperature to feel hot.
The Correct Answer is A
Effective hand hygiene is crucial in preventing the spread of infections in healthcare settings. The Centers for Disease Control and Prevention (CDC) and other health organizations provide guidelines on proper hand hygiene techniques to ensure maximum effectiveness.
Choice A Reason:
“Rub soap on hands for 20 seconds.”
This is the correct action for effective hand hygiene. According to the CDC, scrubbing your hands for at least 20 seconds is essential to remove germs effectively. This duration ensures that all surfaces of the hands, including the backs, between the fingers, and under the nails, are thoroughly cleaned. The CDC recommends singing the “Happy Birthday” song twice as a timer to ensure you scrub for the full 20 seconds.
Choice B Reason:
“Allow hands and arms to dry.”
While drying hands is an important step in hand hygiene, it is not the primary action that makes hand hygiene effective. The focus should be on the thorough scrubbing and cleaning of the hands. After washing, hands should be dried using a clean towel or air dryer to prevent the transfer of germs from wet hands.
Choice C Reason:
“Hold the hands higher than the elbows.”
This technique is often used in surgical hand antisepsis to prevent water from running from the hands down to the elbows, potentially contaminating the hands again. However, for routine hand hygiene, this is not necessary. The primary focus should be on the thorough washing and scrubbing of the hands.
Choice D Reason:
“Adjust the water temperature to feel hot.”
The temperature of the water is less important than the act of scrubbing itself. The CDC states that hands can be washed with either warm or cold water. The key is to use soap and scrub all surfaces of the hands for at least 20 seconds. Hot water can actually be harsh on the skin and is not required for effective hand hygiene.

Correct Answer is A
Explanation
Choice A Reason:
Restlessness is often one of the earliest signs of hypoxia. When the body experiences low oxygen levels, the brain is one of the first organs to be affected. This can lead to symptoms such as anxiety, agitation, and restlessness as the brain struggles to function properly without adequate oxygen. These symptoms occur because the body is trying to compensate for the lack of oxygen by increasing respiratory and heart rates, which can make a person feel uneasy or restless.
Choice B Reason:
Cyanosis refers to a bluish discoloration of the skin and mucous membranes due to low oxygen levels in the blood. While cyanosis is a significant indicator of hypoxia, it is typically a later sign. By the time cyanosis is visible, hypoxia has usually been present for some time, and oxygen levels have been critically low. Therefore, it is not the earliest clinical manifestation of hypoxia.
Choice C Reason:
Apnea is the absence of breathing. This is a severe and late sign of hypoxia. When a person stops breathing, it indicates that the body has been deprived of oxygen for an extended period, leading to critical conditions. Apnea is a medical emergency and requires immediate intervention, but it is not an early sign of hypoxia.
Choice D Reason:
Bradycardia is a slower than normal heart rate. Like apnea, bradycardia is a late sign of hypoxia. Initially, the body responds to low oxygen levels by increasing the heart rate (tachycardia) to pump more oxygenated blood to tissues. Bradycardia occurs when the body can no longer compensate, and the heart rate slows down, indicating severe hypoxia and impending failure of the cardiovascular system.
Correct Answer is C
Explanation
Choice A Reason:
Open the client’s visual acuity using a Snellen chart is incorrect. This action assesses cranial nerve II (optic nerve), which is responsible for vision. The Snellen chart is used to measure visual acuity, not the function of cranial nerve VI
Choice B Reason:
Whisper none of the client’s ears while blocking the other is incorrect. This action assesses cranial nerve VIII (vestibulocochlear nerve), which is responsible for hearing and balance. Whispering tests the auditory function of this nerve.
Choice C Reason:
Ask the client to inspect up is correct. Cranial nerve VI (abducens nerve) controls the lateral rectus muscle, which is responsible for moving the eye outward. Asking the client to look up and outward helps assess the function of this nerve.
Choice D Reason:
Ask the client to smile is incorrect. This action assesses cranial nerve VII (facial nerve), which controls the muscles of facial expression. Smiling tests the motor function of this nerve.
