Which one of the following is not true for increased intracranial pressure (ICP) in infants?

BHU NO - 2015

Child Health Nursing (Pediatrics)

Hard

Appeared in: BHU NO - 2015

Explanation

Increased blood pressure (hypertension) is a component of Cushing's triad, which also includes bradycardia (slow heart rate) and irregular respirations.
Cushing's triad is a late and grave sign of severely increased ICP, indicating that the brainstem is being compressed.
This response is a pre-terminal event and is not considered a typical or early sign of rising ICP in infants.
Therefore, compared to the other options which are earlier indicators, increased BP is the exception.

Option A: Drowsiness, or a change in the level of consciousness (like irritability or lethargy), is one of the earliest and most sensitive signs of increased ICP in an infant.
Option C: A tense or bulging fontanelle is a classic and reliable sign of increased ICP in infants because their cranial sutures have not yet fused, allowing the skull to expand under pressure.
Option D: Vomiting, which may be forceful and projectile, is a common symptom of increased ICP at any age, caused by pressure on the brainstem's vomiting center.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Identification of signs and symptoms of increased intracranial pressure (ICP) in infants as background academic context rather than a clinical decision trigger.
Early recognition of increased ICP is critical for preventing irreversible brain damage. Nurses must be vigilant in assessing for subtle changes in an infant's behavior, feeding patterns, and fontanelle tension.
A high-pitched, neurogenic cry is another key early sign of increased ICP in infants that a nurse should be alert for.
Accurate measurement of head circumference is a vital nursing intervention, as a rapid increase can be an early indicator of conditions causing increased ICP, like hydrocephalus.

How to Approach the Question

First, identify the core of the question: it asks to find the sign that is 'not true' for increased ICP in infants. This means three options are true signs, and one is the exception.
Recall or look up the signs and symptoms of increased ICP, paying special attention to the pediatric/infant population.
Evaluate each option: Drowsiness (altered LOC), Bulging fontanelle, and Vomiting are all well-known, common signs.
Consider the option 'Increased BP'. While it is a sign, think about its timing and significance. Hypertension is part of Cushing's triad, a late and critical finding.
Compare the options. Drowsiness, bulging fontanelle, and vomiting are earlier signs. Increased BP is a late sign.
Conclude that 'Increased BP' is the exception in the context of a typical or early presentation, making it the most likely correct answer for a 'not true' question.
