What is a common sign of digoxin toxicity?
Vomiting.
Tachycardia.
Bradypnea.
Seizures.
The Correct Answer is A
The correct answer is Choice A.Choice A rationale: Vomiting is a common sign of digoxin toxicity. It occurs due to the drug's effects on the gastrointestinal system, which can lead to nausea and vomiting as the body attempts to expel the toxin. This symptom is particularly significant as it can indicate elevated digoxin levels that may require medical intervention.Choice B rationale: Tachycardia, or an increased heart rate, can occur with digoxin toxicity; however, it is more commonly associated with inadequate therapeutic levels rather than toxicity itself. Digoxin usually causes bradycardia (a slower heart rate) when at therapeutic levels, making tachycardia less indicative of toxicity.Choice C rationale: Bradypnea, or slow breathing, is not a typical sign of digoxin toxicity. While respiratory issues can arise from various conditions, they are not specifically linked to digoxin levels. Monitoring respiratory rate is essential in clinical settings but does not directly correlate with digoxin toxicity.Choice D rationale: Seizures are not a common sign of digoxin toxicity. While severe cases might lead to neurological symptoms due to electrolyte imbalances or other complications, seizures are not typically associated with digoxin overdose. Instead, they may suggest other underlying issues requiring evaluation.

Correct Answer is A
Explanation
The correct answer is choice A.
Choice A rationale:
Drawing is the most appropriate activity for developing fine motor skills in school-age children. Drawing involves precise hand movements, control of a writing instrument, and attention to detail. These skills contribute to fine motor skill development and hand-eye coordination.
Choice B rationale:
Singing is not directly related to fine motor skill development. While it can promote cognitive and social development, it does not require the same level of fine motor control as activities like drawing or writing.
Choice C rationale:
Swimming is a gross motor activity that focuses more on large muscle groups and overall coordination. It does not specifically target the refinement of fine motor skills.
Choice D rationale:
Soccer is also a gross motor activity that involves running, kicking, and coordination with teammates. While it promotes physical fitness and coordination, it does not emphasize the fine motor control required for activities like drawing.
Correct Answer is B
Explanation
The correct answer is Choice B: Dry skin.
Choice A rationale:
Diarrhea is not a common clinical manifestation of juvenile hypothyroidism. Hypothyroidism is characterized by an underactive thyroid gland, leading to a decrease in metabolic activity. Symptoms of hypothyroidism include fatigue, weight gain, cold intolerance, constipation, and dry skin, but not diarrhea.
Choice B rationale:
Dry skin is a common clinical manifestation of juvenile hypothyroidism. The decreased thyroid function results in a slower metabolic rate, which can lead to dry and coarse skin due to reduced oil production. This symptom is often seen in hypothyroid patients.
Choice C rationale:
Insomnia is not a common clinical manifestation of juvenile hypothyroidism. Hypothyroidism usually leads to fatigue and excessive sleepiness rather than insomnia.
Choice D rationale:
Accelerated growth is not a common clinical manifestation of juvenile hypothyroidism. In fact, the opposite is true. Hypothyroidism in children can lead to growth retardation due to the decreased metabolic rate and altered hormonal balance.
