RN Maternal Nursing OB Newborn 2023 2024 Exam -Nurselytic

Correct Answer: C

Rationale: Tube feeding is often recommended for premature infants who may not have the ability to suck and swallow effectively. It ensures they receive adequate nutrition.

Correct Answer: D

Rationale: The placenta protects the fetus, removes waste, and facilitates nutrient and gas exchange.

Correct Answer: D

Rationale: The correct answer is D: All of the above. After a cesarean delivery, a combination of pain relief methods is recommended to effectively manage postoperative pain. Epidural anesthesia provides continuous pain relief, intravenous opioids offer immediate relief, and patient-controlled analgesia allows the patient to self-administer pain medication as needed. Using all three methods ensures comprehensive pain management.

Choices A, B, and C on their own may not offer sufficient pain relief compared to the combined approach of using all three methods.

Correct Answer: C

Rationale:
Correct Answer: C - Hypotension


Rationale:
1. Opioid analgesics can cause vasodilation leading to hypotension.
2. Epidural administration can further potentiate the hypotensive effect.
3. Monitoring for hypotension is crucial to prevent complications like decreased perfusion.

Incorrect

Choices:
A: Hyperglycemia - Opioids are not known to cause hyperglycemia.
B: Bilateral crackles - Indicates pulmonary issues, not related to opioids.
D: Polyuria - Not a common adverse effect of opioids.

Correct Answer: A

Rationale: The correct answer is A: Vastus lateralis. For newborns, the vastus lateralis muscle is the preferred site for IM injections due to its larger muscle mass, lower risk of hitting nerves or blood vessels, and better absorption of the medication. The site is located on the lateral aspect of the thigh, making it easily accessible and safe for injections. The other choices are incorrect for newborns: B (dorsogluteal) is not recommended due to the risk of sciatic nerve injury, C (deltoid) is typically used for older children and adults, and D (rectus femoris) is not a commonly used site for IM injections in newborns.
