The nurse observes that a client with sickle cell anemia and on a blood transfusion regimen has cardiac dysrhythmias due to iron overdose toxicity. Which medication is most beneficial to this client?
Trientine
Dimercaprol
Ferrous gluconate
Defaroxamine
The Correct Answer is D
A. Trientine: Trientine is a medication used to treat copper overload in conditions like Wilson's disease. It is not indicated for iron overdose or toxicity.
B. Dimercaprol: Dimercaprol, also known as BAL (British Anti-Lewisite), is a chelating agent used to treat heavy metal poisoning but is not primarily used for iron overload or toxicity.
C. Ferrous gluconate: Ferrous gluconate is an iron supplement used to treat iron-deficiency anemia by providing additional iron to the body. It is not appropriate for treating iron overdose, as it would worsen the situation.
D. Deferoxamine.
Iron overdose, also known as iron toxicity, can lead to serious complications, including cardiac dysrhythmias. Deferoxamine is a chelating agent used to remove excess iron from the body in cases of iron overload or toxicity, such as in patients with conditions like sickle cell anemia who require frequent blood transfusions. It binds to excess iron and helps excrete it from the body, reducing the risk of iron-related complications, including cardiac issues.

Correct Answer is C
Explanation
A. Introducing new foods every day does not allow sufficient time to monitor for adverse reactions.
B. Waiting 8 to 10 days between introducing new foods is a longer interval than typically recommended. It may unnecessarily delay the introduction of a variety of foods to the infant's diet.
C. 5 to 7 days.
When introducing new foods to an infant, it's important to do so gradually to monitor for any potential allergic reactions or sensitivities. Waiting 5 to 7 days between introducing new foods allows for observation of any adverse reactions, such as allergies or digestive issues. This approach helps in identifying the specific food responsible for any adverse reactions and ensures the infant's safety.
D. Waiting 2 to 3 days is too short of an interval to adequately monitor for adverse reactions. Waiting 5 to 7 days provides a better balance between introducing new foods and monitoring for potential issues.
Correct Answer is C
Explanation
Option A is incorrect because Tanner staging is not solely based on developmental achievement according to age. It assesses physical development irrespective of age.
Option B is incorrect because it is not based on the color of pigmentation on the scrotum but rather on multiple physical characteristics.
Option C. Based on the development of pubic hair in girls.
The Tanner staging system, also known as sexual maturity rating or sexual maturity scale, is a system used to assess the sexual development of children and adolescents based on physical characteristics, primarily focusing on secondary sexual characteristics. It is used to assess the stage of puberty in both boys and girls. In the case of girls, it includes the development of pubic hair, breast development, and other changes like the growth of the areola.
Option D is incorrect because it doesn't solely focus on staged voice changes in males. The Tanner staging system includes a range of characteristics, including voice changes, genital development, and pubic hair growth, to assess sexual maturity in both males and females.
