Correct Answer: B

Rationale: Nitrous oxide, also known as "laughing gas," is a safe and effective pharmacological option for pain management during labor. Nitrous oxide is commonly used in labor and delivery settings as it has minimal effects on the baby and allows the woman to remain in control of her pain management. It provides quick pain relief when inhaled and can be adjusted to the woman's needs during labor. Ibuprofen, morphine, and diazepam are not typically used for pain management during labor due to their potential risks and side effects, especially for the baby.

Correct Answer: B

Rationale: Uterine hyperstimulation, also known as tachysystole, is a condition where the uterus contracts too frequently and/or too forcefully, leading to a decreased uterine blood flow. This can result in maternal fatigue and decreased oxygenation to the fetus, as mentioned in the scenario. Uterine hyperstimulation can be caused by several factors, including the excessive use of uterotonic medications, such as oxytocin, or the presence of uterine abnormalities.

Correct Answer: B

Rationale: When managing a conscious patient with a severe nosebleed (epistaxis), the appropriate intervention is to have the patient sit upright and lean slightly forward to prevent blood from flowing into the throat and causing choking or swallowing. Pinching the soft part of the nose just below the bony part can help apply pressure to the bleeding vessel and stop the bleeding. This maneuver also helps compress the blood vessels in the nose, promoting clot formation and stopping the bleeding. It is important not to tilt the head back as this can cause blood to flow into the throat and potentially lead to swallowing, choking, or aspiration. Packing the nose with cotton gauze should be done by medical professionals if the bleeding does not stop with direct pressure. Applying direct pressure to the forehead is not effective for managing nosebleeds; pressure should be applied to the nostrils instead.

Correct Answer: D

Rationale: The Somogyi effect, also known as rebound hyperglycemia, is a phenomenon observed in patients with diabetes mellitus during sleep. It is characterized by a low blood sugar level (hypoglycemia) followed by high blood sugar (hyperglycemia) in the morning. This occurs due to limited insulin in the body during the night, leading to high blood sugar levels in the morning as a response to the hypoglycemia episode. Too much globulin or albumin are not directly associated with the Somogyi effect. Increasing insulin in the body would rather help prevent the hypoglycemia episode that triggers the rebound hyperglycemia in the Somogyi effect.

Correct Answer: A

Rationale: Administering a stool softener as ordered is the most appropriate nursing intervention for a postpartum client experiencing severe perineal pain and difficulty passing stools following a vaginal delivery. Stool softeners help to soften the stool, making it easier for the client to pass without straining, which can exacerbate perineal pain. It is important to follow the healthcare provider's orders when administering medications to ensure proper dosing and effectiveness. Encouraging the client to refrain from defecation may lead to constipation and worsen the situation. Applying ice packs to the perineum can provide temporary pain relief, but addressing the underlying issue of constipation with a stool softener is more effective in the long term. Providing education on proper perineal hygiene is important for overall postpartum care, but addressing the immediate issue of constipation with a stool softener takes precedence in this scenario.
