A nurse is assessing the fontanels of an 8-month-old infant.
Which of the following findings should the nurse recognize as an expected finding?
The anterior fontanel is open.
The posterior fontanel is open.
Both fontanels show molding.
Both fontanels are the same size.
The Correct Answer is A
Choice A rationale:
The anterior fontanel is open in an 8-month-old infant. The anterior fontanel, located at the top of the baby's head where the skull bones have not yet fused, typically closes between 12 to 18 months of age. It is a normal finding in an 8-month-old infant.
Choice B rationale:
The posterior fontanel closes earlier than the anterior fontanel, usually within the first few months of life. It is a smaller diamond-shaped area located at the back of the baby's head. It is not expected to be open in an 8-month-old infant.
Choice C rationale:
Molding refers to the shaping of the fetal head during passage through the birth canal. It can cause temporary changes in the shape of the baby's skull. By 8 months of age, molding is not an expected finding as the skull bones have had time to return to their normal shape.
Choice D rationale:
Both fontanels being the same size is not a typical finding. The anterior fontanel is larger than the posterior fontanel, and their sizes are proportional. Any significant deviation from this proportion could indicate abnormal skull development and should be further assessed.

Correct Answer is D
Explanation
Explanation: Yellow patches in the mouth are an indication of oral candidiasis, also known as thrush, which is a fungal infection caused by Candida albicans. Oral candidiasis can cause symptoms such as pain, burning, redness, and difficulty swallowing in addition to yellow patches on the tongue, palate, cheeks, or throat. Hearing loss, night sweats, and
brittle nails are not manifestations of candida infection.
Correct Answer is C
Explanation
Choice A rationale:
Heart rate 58/min. Clozapine, an atypical antipsychotic medication, can cause bradycardia (slow heart rate) as a side effect. However, the heart rate of 58/min is within the normal range for adults, so it is not a contraindication for clozapine administration.
Choice B rationale:
Fasting blood glucose 100 mg/dL. A fasting blood glucose level of 100 mg/dL is within the normal range (70-99 mg/dL) for adults. It is not a contraindication for clozapine administration.
Choice C rationale:
WBC count 2,900/mm3. Clozapine can cause agranulocytosis, a severe reduction in white blood cell (WBC) count, which can lead to increased susceptibility to infections. A WBC count of 2,900/mm3 is significantly below the normal range (4,000-11,000/mm3) and is a contraindication for clozapine administration due to the risk of severe immunosuppression.
Choice D rationale:
Hgb 14 g/dL. Hemoglobin (Hgb) level of 14 g/dL is within the normal range for adult males (13.8-17.2 g/dL) and females (12.1-15.1 g/dL). It is not a contraindication for clozapine administration.
