Which option below correctly represents a step that is part of the RODS acronym for airway difficulty?

• A. Restricted mouth opening
• B. Obstruction/obese or late pregnancy
• C. Distorted or disrupted airway
• D. Stiff or increased airway pressure

Answer: (A)

The main idea being tested is recognizing what the R in the RODS airway-difficulty mnemonic stands for. RODS is used to quickly flag factors that can make airway management harder. The R stands for restricted mouth opening, which directly signals that you may have trouble getting a blade or other airway devices into the mouth and achieving a good view during laryngoscopy. When mouth opening is limited, it can prevent proper alignment of the oral, pharyngeal, and laryngeal axes, making direct visualization of the vocal cords and intubation more challenging. This is why restricted mouth opening is a clear representation of the R component—the sign that you may need alternative techniques or plans, such as using a different instrument, considering a video laryngoscope, or preparing for an awake or alternative airway approach. The other items correspond to the remaining parts of the acronym—factors indicating other ways the airway can be difficult (obstruction/obesity or late pregnancy; distorted or disrupted airway; stiff or increased airway pressure)—but the option that maps to the R component specifically is restricted mouth opening.
