A nurse is evaluating the allergy profile of a client who has Graves' disease and is to undergo a thyroid scan. The nurse should identify which of the following allergies as a contraindication for the client to undergo a thyroid scan?

A: Tucking the chin while swallowing can actually help prevent aspiration in clients with dysphagia, as it narrows the tracheal opening and helps direct food away from the airway.

B: Sitting upright during meals is a recommended practice to reduce the risk of aspiration. It allows gravity to assist with the movement of food, reducing the likelihood of it entering the airway.

C: Pocketing food on one side of the mouth can be a sign of reduced sensation or motor control on that side, often a result of a stroke. This can lead to unnoticed accumulation of food which may then be aspirated.

D: A cough reflex is a protective mechanism against aspiration. If food enters the airway, the cough reflex should trigger, helping to expel the food from the airway and prevent aspiration.

A. A head circumference 1 cm greater than the chest is within normal variations and does not typically require immediate notification.

B. A positive Babinski reflex is a normal finding in newborns and does not warrant immediate notification.

C. Passage of meconium stool within the first 24 hours of life is considered normal and does not require notification.

D. The pinna (ear) below the outer canthus of the eye can indicate a condition called low-set ears, which may be associated with genetic syndromes or other abnormalities. This finding warrants notification to the provider for further evaluation.
