Seborrheic dermatitis in infants is referred to as:

Rationale:
A. Oral corticosteroids are generally reserved for severe, widespread, or refractory atopic dermatitis due to potential systemic side effects, and topical antihistamines are not routinely recommended because of limited efficacy and risk of skin reactions.
B. A low-potency topical steroid applied three times daily helps reduce inflammation in mild to moderate atopic dermatitis while minimizing risk of skin atrophy. An oral antihistamine at bedtime can help control itching and improve sleep, addressing the patient’s restlessness at night.
C. Medium-potency topical steroids are usually unnecessary for mild erythematous lesions without excoriation and increase the risk of adverse effects in toddlers. Topical antihistamines are generally avoided.
D. Topical antibiotics are indicated only if there is evidence of secondary bacterial infection. Routine use in non-infected atopic dermatitis is not recommended. Oral antihistamines three times daily are not standard; bedtime dosing is preferred to reduce daytime sedation.

Rationale:
A. Blood pressure typically decreases slightly in early pregnancy due to vasodilation rather than increasing.
B. Softening of the cervix, known as Goodell’s sign, is an early physical change observed in pregnancy and is a reliable clinical indicator along with other signs such as Chadwick’s sign (bluish discoloration of the cervix and vagina).
C. Vaginal pH becomes more acidic during pregnancy, not alkaline, due to increased lactic acid from lactobacilli.
D. Hyperpigmentation, rather than hypopigmentation, may occur in areas such as the areolae, linea nigra, and face (melasma) during pregnancy.
