COT Visual Assessment 5 — Questions and Answers
Question 1: During a visual assessment of a patient's skin, you notice a lesion that is flat, non-palpable, and less than 1 cm in diameter with a distinct color change from surrounding skin. How would you correctly document this finding?
- Papule
- Macule (Correct answer)
- Vesicle
- Plaque
Correct answer: Macule
A macule is a flat, non-palpable skin lesion less than 1 cm in diameter that differs in color from surrounding skin. It cannot be felt upon palpation, distinguishing it from a papule (raised) or vesicle (fluid-filled). A plaque is larger than 1 cm and elevated.
Question 2: When performing a visual assessment of a patient's respiratory pattern, you observe that the patient's breathing gradually increases in depth and rate, then decreases, followed by a period of apnea. This pattern repeats cyclically. What is this breathing pattern called?
- Kussmaul respirations
- Biot's respirations
- Cheyne-Stokes respirations (Correct answer)
- Apneustic breathing
Correct answer: Cheyne-Stokes respirations
Cheyne-Stokes respirations are characterized by a cyclic pattern of gradually increasing then decreasing depth and rate of breathing, followed by a period of apnea. This pattern is often associated with heart failure, increased intracranial pressure, or neurological injury. Biot's has irregular clusters with sudden apnea; Kussmaul is deep and labored without the cyclic variation.
Question 3: A COT is performing a visual assessment of a patient's eye and notices that the sclera appears yellow. Which term correctly describes this finding and what does it suggest?
- Pallor — indicating anemia
- Icterus — indicating elevated bilirubin levels (Correct answer)
- Cyanosis — indicating hypoxemia
- Erythema — indicating inflammation
Correct answer: Icterus — indicating elevated bilirubin levels
Yellow discoloration of the sclera is called icterus (or jaundice) and is caused by elevated bilirubin levels in the blood, which can indicate liver disease, bile duct obstruction, or hemolytic conditions. Pallor refers to paleness, cyanosis is a bluish discoloration indicating poor oxygenation, and erythema is redness from inflammation.
Question 4: While visually assessing a patient's abdomen, you observe a bluish discoloration around the umbilicus. This finding is known as which sign, and what condition is it classically associated with?
- Grey Turner's sign — retroperitoneal hemorrhage
- Cullen's sign — intraperitoneal or retroperitoneal hemorrhage (Correct answer)
- McBurney's sign — appendicitis
- Rovsing's sign — appendicitis
Correct answer: Cullen's sign — intraperitoneal or retroperitoneal hemorrhage
Cullen's sign is periumbilical bruising or bluish discoloration around the navel caused by subcutaneous hemorrhage tracking from intraperitoneal or retroperitoneal bleeding. It is classically associated with ruptured ectopic pregnancy or acute hemorrhagic pancreatitis. Grey Turner's sign involves flank discoloration. McBurney's and Rovsing's signs are assessed by palpation, not visual observation.
Question 5: During a visual assessment, a COT observes that a patient has a barrel-chest deformity with an increased anterior-posterior diameter. The patient also appears to be using pursed-lip breathing. Which underlying condition is most consistent with these combined visual findings?
- Pneumonia
- Pulmonary embolism
- Chronic obstructive pulmonary disease (COPD) (Correct answer)
- Pleural effusion
Correct answer: Chronic obstructive pulmonary disease (COPD)
Barrel chest (increased AP diameter due to chronic air trapping) combined with pursed-lip breathing (to maintain positive end-expiratory pressure and slow expiration) are classic visual signs of COPD, particularly emphysema. These adaptations develop over time due to chronic hyperinflation. Pneumonia and pulmonary embolism are acute conditions without these chronic structural changes, and pleural effusion presents differently.
Question 6: A COT is visually assessing a patient's lower extremities and notes that one calf is visibly more swollen than the other, with the skin appearing shiny and taut. The overlying skin is also erythematous and warm-looking compared to the opposite limb. Which condition should this visual presentation prompt you to suspect first?
- Cellulitis only, as the erythema is the primary concern
- Deep vein thrombosis (DVT), given the unilateral swelling and skin changes (Correct answer)
- Bilateral lymphedema presenting asymmetrically
- Arterial insufficiency causing dependent edema
Correct answer: Deep vein thrombosis (DVT), given the unilateral swelling and skin changes
Unilateral calf swelling with shiny, taut skin and overlying erythema and warmth is a classic visual presentation of deep vein thrombosis (DVT). The asymmetry is a key distinguishing feature — bilateral conditions like lymphedema or venous insufficiency typically affect both limbs. While cellulitis causes erythema, the unilateral swelling pattern together with skin changes raises DVT as the primary concern requiring urgent evaluation.
During a visual assessment of a patient's skin, you notice a lesion that is flat, non-palpable, and less than 1 cm in diameter with a distinct color change from surrounding skin.
