Blind finger sweeps are not recommended in an infant with airway restriction due to a foreign object because they may inadvertently force the object deeper into the airway. A finger sweep should only be used if the object can be visualized. Injury to the oral cavity would not be a primary concern in the case of airway restriction, and a finger sweep would not be expected to trigger either gasping or vomiting in an infant.

The most likely cause of his symptoms is hypoglycemia, which is defined as a blood glucose below in a non-diabetic patient. The symptoms of hypoglycemia include altered consciousness, tremors, weakness, vertigo, headaches, heart palpitations, and a bounding pulse.

A temperature of is not considered abnormal as it may reflect a normal variation in body temperature.

His blood pressure is slightly elevated, but it is unclear whether this is typical for him or whether this represents a significant change from his normal blood pressure. Regardless it would not likely be sufficiently elevated to cause his symptoms.

It is also possible he may be experiencing a panic attack, but in the presence of his depressed blood sugar (and absence of signs of anxiety), hypoglycemia is the most likely cause of his symptoms.

Abdominal rigidity and decreased bowel sounds are classic signs of peritontis. In addition, the patient will often want to lie very still, as any motion often increases pain. Cystitis, ulcerative colitis, and cholecystitis all may cause significant abdominal tenderness but would not generally result in rigidity or decreased bowel sounds.

The four main categories of shock are as follows:

• Cardiogenic: Sudden inability of the heart to pump sufficient blood to the body, most commonly due to acute myocardial infarction.
• Hypovolemic: Due to loss of fluids or hemorrhage.
• Septic: Also known as endotoxic shock. Dangerously low blood pressure as the result of systemic inflammatory response to infection.
• Anaphylactic: Systemic inflammatory response to an allergen.
