A nurse is caring for a client who had an arterial blood gas drawn. The pH on the ABG is 7.10. What acid-base imbalance does this client have?

The correct answer is d) Tighten the abdominal muscles while exhaling.

Choice A Reason:

“Raise both shoulders while breathing deeply” is incorrect. Diaphragmatic breathing focuses on using the diaphragm rather than the shoulders. Raising the shoulders can lead to shallow chest breathing, which is less effective for oxygen exchange.

Choice B Reason:

“Inhale through the mouth” is incorrect. For diaphragmatic breathing, it is recommended to inhale through the nose. This helps filter, warm, and humidify the air before it reaches the lungs.

Choice C Reason:

“Exhale through the nose” is incorrect. While exhaling through the nose is beneficial in some breathing exercises, diaphragmatic breathing typically involves exhaling through pursed lips. This technique helps slow down the exhalation and keeps the airways open longer.

Choice D Reason:

“Tighten the abdominal muscles while exhaling” is correct. Tightening the abdominal muscles helps push the diaphragm up, forcing air out of the lungs more efficiently. This action is a key component of effective diaphragmatic breathing.

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.
