The nurse is administering an intramuscular injection of an antibiotic to a 3-month-old infant. Which would be the best site for the nurse to give this medication?

Vastus lateralis muscle

Deltoid muscle

Dorsogluteal muscle

Ventrogluteal muscle

Answer and Explanation

The Correct Answer is A

Choice A reason: The vastus lateralis is the preferred site for IM injections in infants, as it is well-developed, has minimal nerves and vessels, and accommodates safe volumes. This aligns with pediatric nursing injection guidelines, making it the best choice for a 3-month-old receiving an antibiotic intramuscularly.

Choice B reason: The deltoid muscle is underdeveloped in a 3-month-old, with insufficient muscle mass for safe IM injections. The vastus lateralis is safer and more developed, making this incorrect, as the deltoid risks injury or inadequate drug absorption in infants receiving intramuscular injections.

Choice C reason: The dorsogluteal muscle is avoided in infants due to proximity to the sciatic nerve and underdeveloped gluteal mass, risking nerve damage. The vastus lateralis is safer, making this incorrect for a 3-month-old, as it poses significant safety concerns for IM antibiotic injections.

Choice D reason: The ventrogluteal muscle is safe in older children but less accessible in infants due to small muscle mass and positioning challenges. The vastus lateralis is preferred for its accessibility and safety, making this incorrect for a 3-month-old’s IM antibiotic injection in clinical practice.

Correct Answer is A

Explanation

Choice A reason: The infant’s eustachian tube is straighter and wider, increasing susceptibility to infections due to easier pathogen access. This anatomical difference is accurate, aligning with pediatric otolaryngology evidence, making it the most correct statement about children’s ear and hearing development discussed among peers.

Choice B reason: Children’s hearing is acutely developed at birth, not delayed until age 5. Newborns respond to sounds, and hearing matures early. This statement is inaccurate, as it misrepresents the timeline of auditory development, making it incorrect compared to the eustachian tube fact in infants.

Choice C reason: Infants respond to sounds from birth, with noticeable reactions by 1-3 months, not 6 months. This statement underestimates early auditory responsiveness, making it less accurate than the eustachian tube’s anatomical description, which is a key factor in pediatric ear health discussions.

Choice D reason: The eardrum (tympanic membrane) is between the outer and middle ear, not the middle and inner ear. This anatomical error makes the statement incorrect, as the eustachian tube’s structure is the most accurate fact about children’s ear and hearing anatomy in this context.

A. “Milk is a perfect food, and babies should be able to have all the milk they want.” B. “Children have a hard time getting enough iron from food during their first few years.” C. “A family’s economic problems are often a cause of malnutrition.” D. “Caregivers sometimes don’t understand the importance of iron and proper nutrition.”

Correct Answer is A

Explanation

Choice A reason: Milk is not a perfect food, as excessive intake in babies can displace iron-rich foods, causing iron-deficiency anemia. This misconception overlooks milk’s low iron content, making it the correct choice for a false statement compared to accurate causes discussed among nurses.

Choice B reason: Children struggle to get enough iron in early years due to rapid growth and limited dietary sources, a true statement. Milk as a perfect food is the misconception, making this correct and incorrect for identifying a false belief about iron-deficiency anemia in children.

Choice C reason: Economic problems contribute to malnutrition, including iron deficiency, by limiting access to nutritious foods, a valid point. The milk misconception directly misleads about dietary causes, making this accurate and incorrect compared to the false statement about milk’s role in anemia prevention.

Choice D reason: Caregivers’ lack of nutrition knowledge can lead to inadequate iron intake, a true cause of anemia. The milk statement is the misconception, as it wrongly promotes milk over iron sources, making this correct and incorrect for identifying the false belief in the discussion.
