Antivenins should be considered in the treatment of all of the following EXCEPT

Correct Answer: E

Rationale: In this question, the correct answer is E, which is not listed among the provided options. Antivenins should be used in the treatment of envenomations from rattlesnakes, scorpions, black widows, and stonefish. Antivenin is a specific treatment for venomous bites or stings. Rattlesnake envenomations can lead to serious tissue damage and systemic effects that require antivenin therapy. Scorpion envenomations can cause neurotoxic effects that may be effectively treated with antivenin. Black widow envenomations can result in severe muscle pain and cramping, which can be alleviated with antivenin. Stonefish envenomations can lead to intense pain and systemic symptoms requiring antivenin. Educationally, understanding the use of antivenins in treating various envenomations is crucial for healthcare providers, especially pediatric nurses, who may encounter these cases in their practice. Being able to differentiate which envenomations require antivenin therapy is essential for providing prompt and effective care to pediatric patients who have been exposed to venomous bites or stings.

Correct Answer: B

Rationale: The correct answer is B) 3 months. Infants typically achieve early head control with a bobbing motion when pulled to sit around 3 months of age. At this stage, their neck muscles are strengthening, allowing them to better control their head movements. Option A) 2 months is too early for infants to have developed the necessary neck muscle strength for this milestone. At 2 months, infants are usually still developing their head control and are not able to exhibit the described bobbing motion. Option C) 4 months is slightly later than the typical age for achieving early head control with a bobbing motion. By 4 months, most infants have already mastered this skill and are progressing to more advanced forms of head control and movement. Option D) 6 months is beyond the expected age for achieving this milestone. By 6 months, infants should have already developed more advanced head control abilities and be working on sitting independently rather than just achieving head control when pulled to sit. Understanding developmental milestones in infants is crucial for pediatric nurses as it helps in monitoring children's growth and development, identifying any potential delays or issues early on, and providing appropriate support and interventions. By knowing the expected ages for different milestones, nurses can better assess and support the health and well-being of infants in their care.

Correct Answer: B

Rationale: The correct answer is B) molar at 6 years. The first permanent teeth to erupt are typically the first molars around the age of 6. This is because the first molars do not replace any primary teeth but instead emerge behind the last primary molars in the back of the mouth. Option A) central incisor at 6 years is incorrect because central incisors are typically the first primary teeth to erupt, not permanent teeth. Option C) premolar lower canine at 6-7 years is incorrect because premolars and canines are usually the second and third permanent teeth to erupt, respectively, after the first molars. Option D) upper canine at 6-7 years is incorrect because canines usually erupt after the premolars, not before them. In an educational context, understanding the sequence of tooth eruption is crucial for healthcare professionals working with pediatric patients. It helps in identifying normal growth and development, detecting potential issues early, and providing appropriate dental care. Educating parents about the timing of tooth eruption can also aid in promoting good oral hygiene practices from a young age.

Correct Answer: B

Rationale: The correct answer is B) Duchenne muscular dystrophy. Duchenne muscular dystrophy is an X-linked recessive disorder characterized by progressive muscle weakness, particularly in the pelvic and shoulder girdle muscles. The hypertrophy of calf muscles seen in this condition is due to muscle degeneration and fibrosis. The trendelenburg gait, where the child sways side to side while walking, is a common manifestation of Duchenne muscular dystrophy due to weakness in the hip muscles. Option A) Becker's muscular dystrophy is similar to Duchenne muscular dystrophy but has a milder course and later onset. It does not typically present with calf muscle hypertrophy seen in this case. Option C) Myotonic muscular dystrophy is characterized by myotonia (prolonged muscle contractions) and muscle wasting, not hypertrophy of calf muscles. Option D) Cerebral palsy is a neurological disorder that affects movement and muscle coordination but does not typically present with calf muscle hypertrophy and trendelenburg gait seen in Duchenne muscular dystrophy. Understanding these distinctions is crucial for pediatric nurses to accurately assess and manage children with neuromuscular disorders. Recognizing the specific signs and symptoms of each condition allows for early intervention and appropriate support for patients and their families.

Correct Answer: B

Rationale: The correct answer is B) Encourage his friends to visit him in the hospital. This option will most enhance the psychosocial development of the 16-year-old male with cystic fibrosis for several reasons. First, maintaining social connections with peers is crucial for adolescents' emotional well-being and sense of normalcy during hospitalization. Having friends visit can provide emotional support, reduce feelings of isolation, and boost morale, contributing positively to his psychosocial development. Option A) Fax his teacher and have homework sent in, while important for academic continuity, does not directly address the psychosocial needs of the patient. It focuses solely on academic concerns and overlooks the emotional support that friends can provide. Option C) Encouraging frequent visits from his grandparents, though beneficial in terms of family support, may not fully meet the socialization needs of a teenager who likely values interactions with peers more at this developmental stage. Option D) Allowing him unlimited phone use to contact friends is a good way for him to stay connected, but physical visits from friends can offer a more personal and immediate form of support that can positively impact his psychosocial well-being. In an educational context, understanding the psychosocial needs of pediatric patients is vital for healthcare providers, especially those specializing in pediatric care like Certified Pediatric Nurses. Encouraging social interactions and support systems for hospitalized adolescents can significantly impact their overall well-being and recovery. This question highlights the importance of considering holistic care that addresses not only the physical but also the psychosocial needs of young patients.
