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

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.

Choice A rationale:
Correction of acidosis is not the primary intervention for vaso-occlusive sickle cell crisis. The crisis primarily involves pain due to the obstruction of blood flow by sickled cells. Correcting acidosis is not a direct treatment for this condition.
Choice B rationale:
Adequate hydration is essential in managing vaso-occlusive sickle cell crisis. Proper hydration helps prevent dehydration, which can worsen the crisis and lead to complications. Hydration helps maintain blood flow and prevent further sickling of red blood cells.
Choice C rationale:
Pain management is a crucial intervention for a child with vaso-occlusive sickle cell crisis. Pain results from tissue ischemia caused by sickled red blood cells. Effective pain management, often with analgesics, helps improve the child's comfort and quality of life during the crisis.
Choice D rationale:
Administration of heparin is not indicated for vaso-occlusive sickle cell crisis. Heparin is an anticoagulant that prevents blood clot formation. In sickle cell crisis, the primary issue is the obstruction of blood flow by sickled cells, not the formation of clots. Administering heparin may not address the underlying problem and can lead to potential complications.
Choice E rationale:
Replacement of factor VIII is not relevant to vaso-occlusive sickle cell crisis. Factor VIII is a protein involved in blood clotting and is primarily used in the treatment of hemophilia, a different condition unrelated to sickle cell crisis.
