A nurse is preparing to administer vitamin K IM to a newborn. Into which of the following muscles should the nurse inject the medication?

Deltoid.

Dorsogluteal.

Ventrogluteal.

Vastus lateralis.

Answer and Explanation

The Correct Answer is D

The correct answer is choice d. Vastus lateralis.

Choice A rationale:

The deltoid muscle is not typically used for newborn injections because it is too small and underdeveloped, making it an inappropriate site for intramuscular injections in this age group.

Choice B rationale:

The dorsogluteal muscle is also not recommended for newborns due to the risk of injury to the sciatic nerve and the muscle’s underdevelopment.

Choice C rationale:

The ventrogluteal muscle, while a good site for older children and adults, is not commonly used for newborns because it is not as easily accessible and developed as the vastus lateralis.

Choice D rationale:

The vastus lateralis muscle, located on the anterolateral aspect of the thigh, is the preferred site for intramuscular injections in newborns. It is well-developed and provides a large muscle mass, making it the safest and most effective site for administering vitamin K.

Correct Answer is A

Explanation

The correct answer is choice A, Maternal hypertension.

Choice A rationale:

Maternal hypertension is widely recognized as the most common risk factor for placental abruption. High blood pressure can cause the placenta to detach from the uterine wall, leading to abruption. In summary, while all the listed factors can contribute to the risk of placental abruption, maternal hypertension stands out as the most common cause, supported by multiple health sources. It’s important for nurses to recognize and manage hypertension in pregnant clients to minimize the risk of this serious complication.

Choice B rationale:

While maternal cocaine use is a significant risk factor for placental abruption due to its vasoconstrictive effects, which can compromise the placental blood flow, it is not as common as maternal hypertension.

Choice C rationale:

Maternal cigarette smoking is also a risk factor for placental abruption. Smoking can lead to a variety of complications in pregnancy, including placental problems, but again, it is less common than hypertension as a cause for abruption.

Choice D rationale:

Maternal battering can lead to trauma which may result in placental abruption. However, it is not considered the most common risk factor when compared to maternal hypertension.

A. Scrambled eggs. B. A high-fiber meal. C. Orange juice. D. Milk.

Correct Answer is C

Explanation

Choice A rationale :

Scrambled eggs. Taking ferrous sulfate with scrambled eggs is not the optimal choice because eggs contain phytates, which can bind to iron and reduce its absorption. Therefore, it may hinder the effectiveness of the iron supplement, and the client may not receive the full benefit of the medication.

Choice B rationale

A high-fibre meal. While fiber is generally beneficial for digestion and overall health, it is not the best choice to take with ferrous sulfate. Fiber can also interfere with iron absorption in the same way as phytates, potentially reducing the medication's effectiveness.

Choice C rationale

Orange juice. The nurse should instruct the client to take the ferrous sulfate with orange juice. Orange juice is an excellent choice because it is rich in vitamin C. Vitamin C enhances the absorption of non-heme iron (the type of iron found in plant-based sources like ferrous sulfate). By taking the medication with orange juice, the client can maximize the absorption of iron and improve the treatment of iron-deficiency anaemia.

Choice D rationale

Milk. Consuming ferrous sulfate with milk is not advisable. Calcium, present in milk, can inhibit the absorption of iron. Therefore, taking the medication with milk might reduce the efficacy of the iron supplement and not provide the desired therapeutic effect.
