Question

The LPN is preparing to administer an injection of vitamin \(\mathrm{K}\) to the newborn. The nurse should administer the injection in the: A. Rectus femoris muscle B. Vastus lateralis muscle C. Deltoid muscle D. Dorsogluteal muscle

Short answer

Answer: B. Vastus lateralis muscle

Step-by-step solution

List the given options for injection sites

Here, we have four options for administering the vitamin K injection to the newborn: A. Rectus femoris muscle B. Vastus lateralis muscle C. Deltoid muscle D. Dorsogluteal muscle

Determine the safest and most appropriate injection site for newborns

The safest and most appropriate injection site for newborns is usually a location with sufficient muscle mass and decreased risk of injury to nerves and blood vessels. According to the American Academy of Pediatrics (AAP), the vastus lateralis muscle is the preferred site for intramuscular injections in newborns due to its large size and reduced risk of injury.

Select the correct answer

Based on the information provided in step 2, the most appropriate injection site for administering vitamin K to the newborn is: B. Vastus lateralis muscle

Key concepts

Intramuscular Injection Sites

When it comes to administering injections, particularly in newborns, selecting the correct intramuscular injection site is crucial for ensuring both efficacy and safety. The vastus lateralis muscle, located on the side of the thigh, is the ideal site for intramuscular injections in newborns, including the administration of vitamin K. This muscle is preferred because it is large enough to accommodate the volume of the medication and is situated away from major nerves and blood vessels, minimizing the risk of injury.

The rectus femoris, another muscle in the thigh, is less commonly used in newborns due to potential discomfort and the risk of affecting the muscle's growth. The deltoid muscle, found in the upper arm, isn't appropriate for newborns due to its smaller size and proximity to the radial nerve and brachial artery. Finally, the dorsogluteal site, located in the buttocks, is not recommended for newborns because of the high risk of hitting the sciatic nerve or major blood vessels.

Key Points

• Vastus lateralis muscle is the preferred site for newborn intramuscular injections.
• Rectus femoris is not commonly used due to potential adverse effects on muscle development.
• The deltoid muscle is too small in newborns for intramuscular injections.
• Dorsogluteal site poses risks due to proximity to the sciatic nerve and blood vessels.

Newborn Care

Caring for newborns involves specialized approaches that prioritize their unique physiology and vulnerability. The administration of vitamin K shortly after birth is one of these crucial interventions, preventing potential bleeding disorders, due to the newborn's low level of vitamin K. Newborn care involves not only the correct administration of medications but also entails thorough monitoring for reactions, maintaining proper hygiene, and ensuring optimal nutrition and warmth.

Effective newborn care practices also include supporting maternal-infant bonding, such as encouraging skin-to-skin contact, and breastfeeding when possible. Regular pediatric check-ups are important to track growth and development and to administer necessary vaccinations according to the recommended schedule.

Key Aspects of Newborn Care

• Administering vitamin K to prevent bleeding disorders.
• Monitoring for any adverse reactions post medication.
• Maintaining cleanliness to reduce the risk of infections.
• Ensuring the newborn is adequately fed and kept warm.
• Promoting maternal-infant bonding to support emotional well-being.

Nursing Best Practices

Nursing best practices are standards of care that ensure patient safety and optimal health outcomes. They involve evidence-based procedures and a personalized approach to patient care. For nurses, applying best practices means being knowledgeable about the most current guidelines, such as those provided by the American Academy of Pediatrics or the Centers for Disease Control and Prevention. It also requires critical thinking skills to assess and apply the appropriate interventions for each patient's unique situation.

Best practices in nursing include maintaining hand hygiene, correctly identifying patients before treatments, regularly assessing pain levels, and documenting all care provided thoroughly and accurately. For nurses administering intramuscular injections, it is crucial to use aseptic techniques, select the proper injection site, and understand the pharmacodynamics and pharmacokinetics of medications.

Essentials of Nursing Best Practices

• Adhering to evidence-based guidelines and protocols.
• Personalizing patient care through comprehensive assessment.
• Upholding rigorous infection control standards.
• Ensuring proper patient identification and documentation.
• Understanding medication properties for safe administration.
