During the preconception phase, the nurse should teach about which infectious diseases as risk factors for maternal complications? (Select all that apply).

Choice A rationale:
Inspiratory stridor. Inspiratory stridor, a high-pitched sound heard during inhalation, is a common symptom of acute epiglottitis. It is caused by the swelling and inflammation of the epiglottis, which can partially obstruct the airway and create a stridor sound during breathing.
Choice B rationale:
Complete obstruction. Using a tongue depressor to examine the throat of a child with acute epiglottitis can potentially lead to a complete airway obstruction. The epiglottis, which is already swollen, can block the airway entirely, leading to respiratory distress and potentially a life-threatening situation.
Choice C rationale:
Sore throat. A sore throat is a common symptom of various respiratory tract infections, including acute epiglottitis. However, the use of a tongue depressor can worsen the swelling and potentially lead to complete airway obstruction, which is a more immediate concern.
Choice D rationale:
Respiratory tract infection. Acute epiglottitis itself is a severe respiratory tract infection, specifically involving the epiglottis. Using a tongue depressor might exacerbate the condition, leading to airway obstruction, but it is not the cause of the respiratory tract infection.

Choice A rationale:

Signs of stress can indeed manifest in various ways, including stomach pains and changes in behavior. However, in this scenario, the child's symptoms of stomach pains, aggression, and stubbornness might indicate a physical problem causing emotional stress. It's essential to consider other possibilities before attributing the symptoms solely to stress.

Choice B rationale:

Developmental delay could be a potential cause of behavioral issues in a child, but it doesn't explain the stomach pains. Moreover, a developmental delay would typically have been identified earlier in the child's life through regular screenings and assessments.

Choice C rationale:

A physical problem causing emotional stress, such as an undiagnosed medical condition, can lead to both stomach pains and behavioral changes. Considering this possibility is crucial in this situation. It's essential to conduct a thorough physical examination and medical evaluation to rule out any underlying health issues.

Choice D rationale:

Lack of adjustment to the school environment could contribute to behavioral problems in a child. However, it's essential to first investigate the physical symptoms, like stomach pains, before solely attributing the behavior to school adjustment issues. Physical health should be thoroughly assessed to rule out any medical causes for the symptoms.
