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:
Repeating auscultation after asking the client to take a deep breath and cough is the first intervention the nurse should take. This action helps to clear any secretions or mucus that might be causing the crackles. If the crackles persist after the client coughs, it indicates that the sounds are likely due to fluid in the lungs, which requires further assessment and intervention. This step ensures that the nurse accurately identifies the cause of the crackles before proceeding with other interventions.
Choice B Reason:
Instructing the client to limit fluid intake to less than 2,000 mL/day might be appropriate in cases of fluid overload or heart failure, but it is not the first intervention. The nurse needs to confirm the cause of the crackles before making any recommendations about fluid intake. Limiting fluid intake without proper assessment could lead to dehydration and other complications.
Choice C Reason:
Placing the client on bed rest in semi-Fowler’s position can help improve lung expansion and oxygenation by reducing pressure on the diaphragm. However, this is not the first intervention. The nurse should first determine if the crackles are due to secretions that can be cleared by coughing. Semi-Fowler’s position is beneficial for patients with respiratory distress, but it does not address the immediate need to reassess lung sounds.
Choice D Reason:
Preparing to administer antibiotics is not the first intervention. Antibiotics are used to treat infections, and the nurse needs to confirm whether the crackles are due to an infection or another cause before administering medication. Immediate administration of antibiotics without proper assessment could lead to inappropriate treatment and antibiotic resistance.
Correct Answer is A
Explanation
Choice A reason: Thrombophlebitis is characterized by inflammation of the vein with the formation of a blood clot. The signs and symptoms include erythema, warmth, edema, and a red line traveling up the vessel, which indicates the presence of inflammation and possible clot formation. This condition requires prompt intervention to prevent further complications such as the spread of infection or the clot traveling to other parts of the body.

Choice B reason: Infiltration occurs when IV fluid or medication leaks into the surrounding tissue. Signs of infiltration include swelling, discomfort, and coolness at the IV site, but it does not typically present with erythema, warmth, or a red line traveling up the vessel. Infiltration is less likely to cause the systemic signs seen in this case.
Choice C reason: Infection at the IV site can cause erythema, warmth, and edema, but it usually does not present with a red line traveling up the vessel. The red line is more indicative of thrombophlebitis, where the inflammation follows the path of the vein. Infection would also likely present with additional systemic signs such as fever.
Choice D reason: Extravasation involves the leakage of vesicant drugs into the surrounding tissue, causing severe local tissue damage. Signs include pain, burning, and blistering at the site, but it does not typically present with a red line traveling up the vessel. Extravasation is more localized and does not follow the vein’s path like thrombophlebitis.
