The parents of a 9-month-old infant tell the nurse that they have noticed foods such as peas and corn are not completely digested and can be seen in their infant's stools. The nurse's explanation of this is based on which of the following?

Correct Answer: D

Rationale: The correct answer is D: "This is normal because of the immaturity of digestive processes at this age." In infants around 9 months old, their digestive systems are still developing and maturing. This immaturity can lead to foods like peas and corn not being completely digested, which is a common occurrence at this age. It is important for the nurse to educate the parents that this is a normal part of the infant's digestive process and usually resolves as the infant grows older. Option A is incorrect because withholding fibrous foods until age 4 years is not necessary. Introducing a variety of solid foods is essential for an infant's nutrition and development. Option B is incorrect as it is too extreme. Withholding all solid foods is not required in this situation unless there are other underlying issues that need to be addressed. Option C is incorrect as seeing undigested food in an infant's stool at this age is often due to the immaturity of the digestive system and does not necessarily indicate a serious problem that requires immediate investigation. Educationally, it is crucial for nurses to understand normal infant development, including digestive processes, to provide accurate information and support to parents. By explaining these normal variations, nurses can alleviate parental concerns and promote confidence in caring for their child.

Correct Answer: B

Rationale: The correct answer is B. When introducing solid foods to infants, it is important to introduce one food item at a time, with intervals of 4 to 7 days between each new food. This allows for the identification of any potential food allergies or intolerances. It is important to proceed gradually and monitor for any adverse reactions.

Correct Answer: D

Rationale: In this question about urethritis, the correct answer is D) N.gonorrhoeae is one of the most commonly identified pathogens, which is NOT true. Rationale: - Option D is incorrect because while N.gonorrhoeae is a common pathogen associated with urethritis, it is not one of the most commonly identified pathogens. Other organisms such as Chlamydia trachomatis are also frequently implicated. - Option A is true because urethritis can present with meatal pruritus, which is itching around the opening of the urethra. - Option B is true as approximately 30-50% of males with urethritis may be asymptomatic carriers, which can lead to underdiagnosis and spread of infection. - Option C is vague in the question and does not provide a clear statement to evaluate. Educational context: Understanding the various manifestations and causes of urethritis is crucial for healthcare providers, especially in pediatric nursing. By knowing the common symptoms, prevalence of asymptomatic carriers, and typical pathogens involved, nurses can accurately assess, diagnose, and treat pediatric patients with urethritis. This knowledge is essential for providing comprehensive care, preventing complications, and promoting public health by controlling the spread of infections.

Correct Answer: D

Rationale: In pediatric nursing, the evaluation for primary amenorrhea is crucial to assess for any underlying health issues. The correct answer is D) 16 years. This is the recommended age for evaluation as it allows for sufficient time for normal pubertal development to occur. By waiting until age 16, healthcare providers can better distinguish between normal variation in puberty and potential medical conditions causing primary amenorrhea. Option A) 12 years is too early for evaluation as many girls may still be within the normal range of pubertal development at this age. Option B) 13 years is also premature for evaluation of primary amenorrhea. Option C) 14 years is closer to the recommended age but may still be too early to definitively diagnose primary amenorrhea. In an educational context, it is important for pediatric nurses to understand the appropriate age for evaluating primary amenorrhea to provide optimal care for adolescent patients. This knowledge helps nurses advocate for timely assessments and interventions when necessary, ensuring the health and well-being of their patients.

Correct Answer: B

Rationale: The correct answer is B) 85%. In pediatric nursing, understanding oxygen therapy is crucial for providing appropriate care to children with respiratory issues. Oxygen masks are commonly used to deliver oxygen to pediatric patients. The percentage of FiO2 that can be delivered via a mask is influenced by the flow rate of oxygen and the type of mask being used. Option A) 35% is incorrect because a simple oxygen mask typically delivers FiO2 of around 40-60% at a flow rate of 5-10 L/min, which is higher than 35%. Option C) 65% is incorrect as well because a non-rebreather mask can deliver oxygen concentrations of around 60-80% at flow rates of 10-15 L/min, surpassing 65%. Option D) 75% is also incorrect as it falls within the range of oxygen concentration delivered by a non-rebreather mask and not the maximum percentage achievable via a mask. Understanding the correct percentage of FiO2 that can be delivered via a mask is essential for nurses to ensure adequate oxygenation in pediatric patients. Proper knowledge of oxygen delivery systems and their capabilities is vital in providing safe and effective care to children with respiratory needs.
