The nurse should teach a pregnant woman that which substances are teratogens? (Select all that apply.).

Choice A rationale:
Adjusting the insulin dosage without proper medical guidance can be dangerous for a child with diabetes. Giving half the regular morning dose without considering the child's current blood glucose levels can lead to hypoglycemia, a potentially life-threatening condition. This choice is unsafe and incorrect.
Choice B rationale:
Substituting simple carbohydrates or calorie-containing liquids for solid foods might help maintain the child's blood glucose levels to some extent. However, it's crucial to ensure that the child's overall nutritional needs are met. In cases of illness, monitoring blood glucose levels and consulting with a healthcare provider are essential. This choice, while not the best option, could be a temporary measure if the child is not eating solid foods due to illness.
Choice C rationale:
Giving the child plenty of unsweetened, clear liquids is the most appropriate choice. This helps prevent dehydration, a common concern when a child is not eating or drinking adequately due to illness. Clear liquids, such as water, clear broths, or oral rehydration solutions, can help maintain hydration and provide some electrolytes. It's essential for parents to monitor the child's condition closely and seek medical advice if the child's condition worsens.
Choice D rationale:
Taking the child directly to the emergency department is not necessary if the child is only experiencing a minor illness and is not eating. However, if the child shows signs of severe dehydration, persistent vomiting, or other concerning symptoms, seeking medical attention promptly is crucial. In the absence of these severe symptoms, choice C is the most appropriate course of action.

Choice A rationale:

Asthma. Rationale: A chronic, nonproductive cough and diffuse wheezing during the expiratory phase of respiration are classic symptoms of asthma. Asthma is a chronic inflammatory condition of the airways characterized by bronchoconstriction, leading to symptoms such as wheezing, coughing, and shortness of breath. These symptoms often worsen during the expiratory phase of respiration, leading to the characteristic expiratory wheezing.

Choice B rationale:

Pneumonia. Rationale: Pneumonia is characterized by inflammation of the lung tissue and is often associated with productive cough, fever, chest pain, and sometimes wheezing. However, diffuse wheezing during the expiratory phase without significant productive cough is not a typical presentation of pneumonia.

Choice C rationale:

Bronchiolitis. Rationale: Bronchiolitis, caused by viruses such as RSV, commonly affects infants and young children. It presents with symptoms such as cough, wheezing, and respiratory distress. However, bronchiolitis typically involves lower airway inflammation and is often associated with viral upper respiratory symptoms. The presented case, with a chronic, nonproductive cough and diffuse wheezing during the expiratory phase, is more indicative of asthma.

Choice D rationale:

Foreign body in the trachea. Rationale: A foreign body in the trachea can cause acute respiratory distress and coughing. While it can lead to wheezing, the chronic nature of the symptoms described in the scenario (chronic, nonproductive cough and diffuse wheezing during the expiratory phase) is not consistent with a foreign body in the trachea.
