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:
Weighing the infant every day on the same scale at the same time is crucial in monitoring excess fluid volume in congestive heart failure. Sudden weight gain can indicate fluid retention, a common sign of worsening heart failure. Daily weight monitoring helps in early detection and timely intervention.
Choice B rationale:
Notifying the physician when weight gain exceeds more than 20 g/day might be too late for intervention. Daily weight monitoring is essential to detect trends and intervene promptly to manage excess fluid volume.
Choice C rationale:
Placing the infant in a car seat to minimize movement is not directly related to managing excess fluid volume in congestive heart failure. It is essential for safety during transportation but does not address the nursing diagnosis.
Choice D rationale:
Administering digoxin as ordered by the physician is a medical intervention for congestive heart failure. While important, the nursing diagnosis is related to excess fluid volume, and the focus should be on nursing interventions such as monitoring daily weights.

Choice A rationale:
Fever as high as 40° C (104° F). Fever is not typically a common sign or symptom of chronic otitis media with effusion (OME). Chronic OME is characterized by the presence of fluid in the middle ear without signs of acute infection. While fever might occur in acute otitis media, it is not a typical feature of chronic OME.
Choice B rationale:
Severe pain in the ear. Severe pain in the ear is more commonly associated with acute otitis media rather than chronic otitis media with effusion. Chronic OME usually presents with a sensation of fullness or hearing loss in the affected ear due to the accumulation of fluid in the middle ear, but it does not cause severe ear pain.
Choice C rationale:
Nausea and vomiting. Nausea and vomiting are not typical signs or symptoms of chronic otitis media with effusion. These symptoms are more likely to occur in conditions affecting the inner ear or vestibular system, not in chronic OME.
Choice D rationale:
A feeling of fullness in the ear. A feeling of fullness in the ear is a common sign of chronic otitis media with effusion. The accumulation of fluid in the middle ear can cause a sense of fullness or pressure in the affected ear. This sensation might be accompanied by mild hearing loss.
