During a routine health assessment, the nurse notes that an 8-month-old infant has a significant head lag. Which is the most appropriate action?

Correct Answer: C

Rationale: In this scenario, the most appropriate action is option C: schedule the child for further evaluation. Head lag in an 8-month-old infant can be a concerning sign of developmental delay or neuromuscular issues. By scheduling the child for further evaluation, the nurse can ensure that any potential issues are identified and addressed promptly. Option A is incorrect because waiting until the next visit may delay necessary intervention if there is an underlying problem. Option B is incorrect because teaching exercises without a proper evaluation could be ineffective or potentially harmful, depending on the cause of the head lag. Option D is incorrect because the status of the anterior fontanel alone is not a definitive indicator of the need for further evaluation in this context. Educationally, this question highlights the importance of recognizing and responding to developmental red flags in pediatric patients. Early identification of developmental delays can lead to timely interventions that can positively impact the child's long-term outcomes. Nurses play a vital role in conducting thorough assessments and collaborating with healthcare providers to ensure optimal care for pediatric patients.

Correct Answer: A

Rationale: The correct answer is A) A normal finding. In a funduscopic examination of a school-age child, a brilliant, uniform red reflex in both eyes is a normal finding. This red reflex is produced by the reflection of light off the retina and is an indicator of normal ocular health. Option B) A sign of a possible visual defect and a need for vision screening is incorrect because a brilliant, uniform red reflex is not indicative of a visual defect in this context. Option C) An abnormal finding requiring referral to an ophthalmologist is incorrect as a brilliant red reflex is not abnormal but rather a normal finding. Option D) A sign of small hemorrhages, which usually resolve spontaneously is also incorrect as this scenario does not suggest any hemorrhages. From an educational perspective, understanding the normal variations in funduscopic examination findings in children is crucial for nurses caring for pediatric patients. Recognizing normal findings helps nurses differentiate between normal variations and abnormalities, leading to appropriate referrals and interventions when needed.

Correct Answer: B

Rationale: In nursing care of children, detecting strabismus early is crucial for optimal vision development. The correct answer is B) Amblyopia, a type of blindness, may result. Strabismus, if left untreated, can lead to amblyopia, where the brain starts to favor one eye over the other, causing vision loss in the weaker eye. This highlights the importance of early detection and intervention to prevent long-term visual impairment. Option A) Color vision deficit may result is incorrect because strabismus primarily affects binocular vision and eye alignment, not color vision. Option C) Epicanthal folds may develop in the affected eye is incorrect as epicanthal folds are unrelated to strabismus but are a common feature in some individuals. Option D) Corneal light reflexes may fall symmetrically within each pupil is incorrect because this statement describes a normal finding, not a consequence of strabismus. Educationally, understanding the implications of untreated strabismus emphasizes the importance of regular vision screenings in children to detect and address visual abnormalities early to promote optimal eye health and development. Nurses play a vital role in advocating for comprehensive eye exams and timely interventions to prevent complications like amblyopia.

Correct Answer: A

Rationale: The most frequently used test for measuring visual acuity is the Snellen letter chart (Option A). This test is widely recognized and utilized in clinical settings due to its simplicity and effectiveness. The Snellen chart consists of rows of letters in varying sizes, with the patient asked to read the smallest line they can see clearly from a standardized distance. This test provides a numerical measurement of visual acuity, such as 20/20 or 20/40, with 20/20 indicating normal vision. The other options (B, C, and D) are not commonly used for measuring visual acuity in the same way as the Snellen chart. The Ishihara vision test (Option B) is specifically designed for color blindness screening, not visual acuity measurement. The Allen picture card test (Option C) is used to assess visual-motor coordination and perception in children. The Denver eye screening test (Option D) is a tool for screening vision problems in children but does not measure visual acuity as precisely as the Snellen chart. In an educational context, understanding the importance of using the appropriate assessment tools for specific purposes is crucial for nursing students. Mastery of common tests like the Snellen chart is essential for accurate assessment and diagnosis in pediatric nursing care. By knowing the strengths and limitations of various tests, nurses can provide quality care and collaborate effectively with other healthcare professionals to meet the needs of pediatric patients.

Correct Answer: C

Rationale: In assessing an infant's visual acuity, it is crucial to understand the developmental milestones related to vision. Infants typically develop the ability to fixate on and follow a target between 3 to 4 months of age. At this stage, their visual system is becoming more coordinated, allowing them to track moving objects with their eyes. This ability is a key indicator of visual maturation and neurological development in infants. Option A (1 month) is incorrect because infants at this age do not yet possess the visual acuity and coordination required to fixate and follow a target accurately. Option B (1 to 2 months) is also incorrect as it falls within the same reasoning as option A. Option D (6 months) is incorrect as well because by this age, infants should have already developed the ability to fixate on and follow a target. Infants who have not achieved this milestone by 6 months may require further evaluation for potential visual or neurological issues. Understanding these developmental milestones is essential for nurses caring for infants as it allows for early detection of any visual or neurological abnormalities. By recognizing the expected age range for visual acuity development, nurses can provide appropriate interventions and referrals to support optimal infant growth and development.
