When teaching a patient who is taking thiazide diuretics, the nurse will encourage the patient to increase the intake of which electrolyte?

A. In roseola (also known as exanthem subitum or sixth disease), a child typically develops a rash that is characterized by small, rose-colored spots (maculopapular rash) after the fever resolves. However, it is not primarily described as a "red papular rash" at the onset, which can lead to some confusion.
B. Koplik spots are small, white lesions that appear inside the mouth and are characteristic of measles, not roseola. They do not occur in roseola.
C. A severe cough is not a symptom of roseola. While respiratory symptoms can be present in many viral infections, roseola is primarily characterized by a high fever followed by a rash, with minimal respiratory involvement.
D. Inflammation of the parotid gland is associated with mumps, not roseola. Roseola does not typically involve swelling of the salivary glands.

A. This is not a typical preoperative instruction for retinal detachment surgery. Pupil constriction is not directly related to the procedure.
B. This is crucial to prevent further damage to the retina. Sudden head movements can exacerbate the detachment.
C. Cool compresses are not typically recommended before retinal detachment surgery. They may not have a significant impact on the condition.
D. While eye patches might be used post-operatively to protect the eyes, it's not a common preoperative instruction.
