When reviewing the medical record of a child, what would the nurse interpret as the most sensitive indicator of intellectual disability?

History of seizures.

Preterm birth.

Vision deficit.

Language delay.

Answer and Explanation

The Correct Answer is D

Choice A rationale

Seizures, while common in children with various neurological disorders, including those with intellectual disability, are not the most sensitive or specific indicator for intellectual disability itself. Seizure disorders can result from many causes, such as structural brain abnormalities, infections, or genetic conditions, and their presence alone does not reliably quantify or define the degree of cognitive impairment.

Choice B rationale

Preterm birth, especially very low birth weight, is a significant risk factor for developmental delays and intellectual disability due to potential damage to the developing brain; however, many preterm infants develop normally. It is an antecedent risk, not a direct measure or the most sensitive clinical indicator of existing intellectual functional limitations.

Choice C rationale

Vision deficits are sensory impairments that can coexist with intellectual disability or be caused by related syndromes, but they are separate developmental domains. A vision deficit does not directly reflect the child's adaptive behavior or intellectual functioning, which are the core components used to define intellectual disability.

Choice D rationale

Language delay is often one of the earliest and most observable indicators of intellectual disability in children, as communication skills are integral to cognitive development and adaptive functioning. Delays in acquiring language milestones, such as using first words or combining words, frequently correlate strongly with underlying cognitive limitations.

Correct Answer is C

Explanation

Choice A rationale

Feeding problems are a common, non-specific finding in early childhood and can be related to many different issues, such as poor latch, reflux, or developmental delays, and are not exclusively indicative of a genetic disorder like Down syndrome. Therefore, this observation is not specific enough to confirm a genetic etiology.

Choice B rationale

Nasal congestion and excess mucus are very common signs of upper respiratory infections or allergic rhinitis in young children. These findings reflect an inflammatory or infectious process in the nasal passages and are not recognized as a primary or specific physical characteristic of a genetic disorder.

Choice C rationale

Low-set ears are a recognized dysmorphic feature or minor congenital anomaly that is often associated with various syndromes, particularly those involving chromosomal abnormalities like Down syndrome, as they reflect atypical fetal development of the first and second branchial arches. Lobe creases, while a potential finding, are less specific than low-set placement.

Choice D rationale

Wheezing suggests obstruction or narrowing in the lower airways, typically associated with conditions like asthma, bronchiolitis, or foreign body aspiration. This is a respiratory symptom related to inflammation and bronchospasm and is not a typical, pathognomonic physical finding of a common genetic disorder.

A. A 16-hour-old newborn who has not passed any meconium. B. A 16-hour-old newborn whose glucose level is 55 mg/dL. C. A 2-day-old newborn who is breathing irregularly at 70 breaths/minute. D. A 2-day-old newborn who is excreting a milky discharge from both nipples.

Correct Answer is C

Explanation

Choice A rationale

The normal range for meconium passage is generally within the first 24 to 48 hours of life. A 16-hour-old newborn who has not yet passed any meconium is still within the expected time frame and is not an immediate cause for alarm, although documentation is important. However, the nurse should continue to monitor for bowel sounds and abdominal distention.

Choice B rationale

The normal blood glucose level for a newborn is typically 45 mg/dL or higher. A glucose level of 55 mg/dL for a 16-hour-old newborn is within the acceptable and safe range, indicating adequate metabolic function and requiring only routine monitoring rather than immediate reporting to the healthcare provider.

Choice C rationale

A respiratory rate of 70 breaths/minute in a 2-day-old newborn (48 hours old) is tachypnea, as the normal range is 30 to 60 breaths/minute. Persistent tachypnea beyond the immediate transitional period, especially when associated with an irregular pattern, is a sign of potential respiratory distress or other underlying pulmonary or cardiac pathology and must be reported immediately.

Choice D rationale

Excreting a milky discharge (sometimes called "witch's milk") from the nipples in both female and male newborns is a common and benign temporary condition caused by the withdrawal of maternal hormones (estrogen and prolactin) after birth. This is a normal, transient finding and does not require reporting to the healthcare provider.
