The nurse must check vital signs on a 2-year-old boy who is brought to the clinic for his 24-month checkup. Which criteria should the nurse use in determining the appropriate-size blood pressure cuff?

The correct answer is choice C.

Choice C rationale:

Placing the avulsed tooth in cold milk is the most suitable medium for transporting it to the dentist. Cold milk helps preserve the viability of the tooth's cells and tissues, which is crucial for successful reimplantation. The temperature and composition of cold milk provide a suitable environment to prevent cell damage.

Choice A rationale:

Placing the tooth in a dry, clean jar is not recommended. A dry environment can cause the tooth's cells to dry out and become nonviable, making reimplantation less successful.

Choice B rationale:

Warm salt water is not the optimal choice for transporting an avulsed tooth. Warm water can cause damage to the tooth's cells, and salt water may not provide the necessary conditions to maintain the tooth's viability.

Choice D rationale:

Placing the tooth in cold water might seem logical, but it is not as effective as cold milk. Cold water lacks the protective properties and nutrients that milk provides, potentially leading to a higher risk of cell damage in the avulsed tooth.

The correct answer is choice A: Anaphylactic shock.

Choice A rationale:

Anaphylactic shock is the correct answer. Anaphylactic shock is a severe and potentially life-threatening allergic reaction that causes massive vasodilation, capillary leakage, and bronchoconstriction. It can occur rapidly after exposure to an allergen such as certain foods, insect stings, medications, or latex. The release of histamine and other inflammatory mediators leads to systemic vasodilation and increased permeability of blood vessels, resulting in a sudden drop in blood pressure and compromised organ perfusion.

Choice B rationale:

Cardiogenic shock is characterized by inadequate cardiac output due to severe heart dysfunction. It is typically caused by conditions like myocardial infarction, heart failure, or other cardiac issues. While allergic reactions can potentially affect the cardiovascular system, the symptoms described in the question are more indicative of anaphylactic shock.

Choice C rationale:

Neurogenic shock results from disruption of sympathetic nervous system control over blood vessel tone, often due to spinal cord injury or severe emotional distress. This leads to widespread vasodilation and a sudden drop in blood pressure. While it can cause hemodynamic instability, it doesn't specifically involve the hypersensitivity reaction and capillary leaks associated with anaphylactic shock.

Choice D rationale:

Hypovolemic shock is caused by a significant loss of blood volume or bodily fluids, leading to decreased intravascular volume and subsequent inadequate tissue perfusion. This shock type is not directly related to a hypersensitivity reaction or capillary leakage caused by allergic responses. 2 / 2
