A fundamental principle of aseptic technique is that any item whose sterility is uncertain must be treated as contaminated.
The scrub person drops a sterile instrument onto the floor. The correct action is to:

When positioning a patient in the lateral decubitus position, the MOST important nursing consideration to prevent injury is:
Answer: Padding all bony prominences and ensuring the axillary roll is placed correctly
Lateral positioning risks brachial plexus injury and pressure injuries; correct axillary roll placement and padding all bony prominences are critical safeguards.
A patient undergoing an abdominal procedure under general anesthesia is at GREATEST risk for which thermoregulatory complication?
Answer: Hypothermia due to heat loss from the open body cavity and anesthesia effects
General anesthesia impairs thermoregulation and open body cavities cause significant radiant and evaporative heat loss, making hypothermia the primary risk.
Which hand-washing technique is recommended before the first surgical case of the day?
Answer: A traditional surgical hand scrub of at least 3–5 minutes using an antimicrobial agent
Before the first case of the day, a traditional timed antimicrobial surgical scrub is required to remove resident and transient flora from hands and forearms.
Malignant hyperthermia (MH) is triggered by which class of agents?

MH is a pharmacogenetic disorder triggered by volatile inhalation agents (e.g., sevoflurane) and the depolarizing agent succinylcholine.
