The nurse is discussing development and play activities with the parent of a 2-month-old boy. Recommendations should include giving him his first rattle at about what age?

Correct Answer: B

Rationale: In pediatric nursing, understanding child development milestones is crucial for providing appropriate care and guidance to parents. The correct answer is B) 4 months because at this age infants start to develop better hand-eye coordination and are able to grasp objects intentionally. Introducing a rattle at 4 months encourages sensory exploration and helps in developing the infant's fine motor skills. Option A) 2 months is incorrect because infants at this age do not have the necessary motor skills to purposefully grasp and play with a rattle. Option C) 7 months and D) 9 months are also incorrect as by these ages, infants should have already been introduced to and engaged in more complex play activities beyond just a rattle. Educationally, it is important for nurses to educate parents on age-appropriate toys and activities to enhance their child's development. By providing accurate information on when to introduce certain toys based on developmental milestones, nurses empower parents to actively participate in their child's growth and learning journey. This guidance fosters a positive parent-child relationship and promotes the child's overall well-being.

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.

Correct Answer: C

Rationale: The correct answer is C) hypertension. Cold water shock is a physiological response that occurs when a person is suddenly immersed in cold water. This response includes several components such as hyperventilation, decreased breath-holding ability, and ectopics (irregular heartbeats). Hypertension, or high blood pressure, is not typically a component of cold water shock. Instead, the body's response to cold water immersion usually involves a rapid increase in heart rate and vasoconstriction to conserve heat and maintain core body temperature. Understanding the components of cold water shock is important for healthcare providers, particularly in pediatric nursing, where accidental drowning incidents can occur. By recognizing the symptoms and understanding the body's response to cold water immersion, nurses can provide appropriate care and interventions to prevent complications and promote positive outcomes for pediatric patients.
