A community health nurse is performing a vision screening on a 4-month-old infant. When shining a light source into the infant's visual field, which of the following is an expected finding?

A. Herpes simplex virus (HSV) type 1 infection is not typically a reportable diagnosis to the CDC unless it is part of a larger outbreak or cluster of cases.

B. Hepatitis A is a reportable infectious disease to the CDC due to its potential for public health significance, particularly in outbreaks or clusters of cases.

C. Human papillomavirus (HPV) infection is not typically a reportable diagnosis to the CDC unless it is part of a larger study or surveillance effort.

D. Pediculosis capitis (head lice infestation) is not typically a reportable diagnosis to the CDC unless it is part of a larger outbreak or cluster of cases.

Rationale for A: Decreased reflexes can indicate hypokalemia, an adverse effect of loop diuretics. Loop diuretics increase the excretion of potassium, which can lead to low potassium levels, manifesting as muscle weakness and diminished reflexes.

Rationale for B: Weight gain, especially in the context of heart failure, suggests fluid retention rather than an adverse effect of a loop diuretic, which is expected to reduce fluid retention by promoting diuresis.

Rationale for C: Increased urinary output is an expected effect of loop diuretics, as they are used to remove excess fluid. This would not be considered an adverse effect unless it leads to dehydration or electrolyte imbalances.

Rationale for D: Jugular vein distention indicates fluid overload, which would suggest that the diuretic is not effective or that the heart failure is worsening. It is not a direct adverse effect of the medication itself.
