The nervous parent asks when the big "soft spot" (anterior fontanel) will be closed. The nurse's most informative response would be

That big soft spot will be covered in bone by the end of the second month

"The big soft spot will close at around 24 months of age

"The big soft spot is usually closed between 12 and 18 months of age

"Babies' saft spots close at different times depending on their growth rate

Answer and Explanation

The Correct Answer is C

A. "That big soft spot will be covered in bone by the end of the second month" is not accurate. The closure usually occurs later than the second month.

B. "The big soft spot will close at around 24 months of age" is an overestimation of the typical closure time. It is usually closed earlier than 24 months.

C. "The big soft spot is usually closed between 12 and 18 months of age."

The anterior fontanel is the soft spot located on the baby's head, and its closure is a natural part of an infant's development. The timing of closure can vary from one child to another. However, the typical range for the closure of the anterior fontanel is between 12 and 18 months of age. This information provides a general guideline for parents while acknowledging the natural variability in child development.

D. "Babies' soft spots close at different times depending on their growth rate" is true to some extent, but providing a general range (option C) is more informative for parents.

Correct Answer is A

Explanation

A. Hypernatremia and Diabetes Insipidus.

The symptoms described, including dry mucous membranes, high urinary output, and seizures, are consistent with hypernatremia, which is an elevated level of sodium in the blood, and Diabetes Insipidus (DI).

Diabetes Insipidus is a condition where the body is unable to properly regulate water balance, leading to excessive thirst and urination. In the presence of DI, water loss is excessive, leading to dehydration, increased sodium levels, and potentially seizures.

B. Hyponatremia and Diabetes Insipidus: This option doesn't align with the symptom of hypernatremia (elevated sodium levels) but suggests low sodium levels (hyponatremia), which would have different symptoms.

C. Hyponatremia and Syndrome of Inappropriate Antidiuretic Hormone (SIADH): This option also suggests low sodium levels (hyponatremia) and a different condition (SIADH) characterized by water retention and dilution of the blood, which is not consistent with the described symptoms.

D. Hypernatremia and Syndrome of Inappropriate Antidiuretic Hormone (SIADH): This option suggests high sodium levels (hypernatremia) but includes SIADH, which would not result in high urinary output. SIADH is characterized by excessive retention of water, leading to low urinary output and concentrated urine.

A. Bone marrow transplantation B. Exchange transfusion C. Liver transplantation D. Administration of intravenous immunoglobulin

Correct Answer is A

Explanation

A. Bone marrow transplantation.

Severe aplastic anemia is a condition characterized by a significant reduction in the number of blood cells produced by the bone marrow. The primary treatment for severe aplastic anemia is a bone marrow transplantation, also known as a stem cell transplant. This procedure involves replacing the patient's dysfunctional bone marrow with healthy bone marrow or stem cells from a suitable donor. This is done to restore normal blood cell production.

Option B (Exchange transfusion) is not the primary treatment for severe aplastic anemia but may be used in certain cases to manage complications or specific symptoms.

Option C (Liver transplantation) is not a treatment for severe aplastic anemia, as this condition primarily affects the bone marrow and blood cell production.

Option D (Administration of intravenous immunoglobulin) is not the primary treatment for severe aplastic anemia but may be used in some cases to manage complications, such as infections. However, it does not address the underlying cause of the disease, which is the failure of the bone marrow to produce enough blood cells.
