A nurse at a health department is providing anticipatory guidance to the parent of a 1-month-old infant.
The nurse should inform the parent that the infant should receive which of the following immunizations at the age of 2 months?

A. Bleeding gums are common during pregnancy due to hormonal changes that make gums more sensitive and prone to bleeding. This is not typically a sign of a serious condition and can usually be managed with good oral hygiene.

B. Faintness or lightheadedness upon rising is common in pregnancy due to blood pressure changes. This can often be managed with lifestyle modifications such as rising slowly, staying hydrated, and avoiding prolonged standing.

C. Swelling of the face during pregnancy can be an early sign of preeclampsia, a serious condition characterized by high blood pressure and organ damage. This is a concerning symptom that requires immediate evaluation by a healthcare provider.

D. Urinary frequency is a common and usually benign symptom during pregnancy, especially in the first and third trimesters due to hormonal changes and pressure on the bladder. It does not typically require urgent reporting unless accompanied by other symptoms such as pain or burning during urination, which could indicate a urinary tract infection.

Choice A rationale:

Hearing loss is not a typical sign of digoxin toxicity. Digoxin toxicity primarily affects the visual system, leading to disturbances such as blurred or yellow-tinted vision. It can also cause various cardiac symptoms due to its effects on heart rhythm and contractility. Hearing loss is not a recognized symptom of digoxin toxicity.

Choice B rationale:

Tachycardia (fast heart rate) can be a sign of digoxin toxicity. Digoxin can cause arrhythmias and alter heart rate, which may lead to tachycardia. While this is a possible symptom, it is not as specific as other manifestations, such as visual disturbances.

Choice C rationale:

Blurred vision is a hallmark sign of digoxin toxicity. Digoxin can cause disturbances in color vision, such as seeing yellow or green halos around objects. Blurred vision is a significant indicator of digoxin toxicity and requires prompt medical attention.

Choice D rationale:

Insomnia is not a recognized symptom of digoxin toxicity. Digoxin toxicity primarily affects the cardiovascular and visual systems, leading to symptoms related to heart rhythm disturbances and vision changes. Insomnia is not a typical manifestation of digoxin toxicity.
