Correct Answer: C

Rationale: Asking about the gestational age is crucial in determining the stage of labor and assessing potential complications. This information helps in understanding the progress of labor and making appropriate decisions regarding the management of the delivery process. Choices A, B, and D are not as pertinent at this point in providing immediate care or assessing the situation compared to knowing the gestational age.

Correct Answer: D

Rationale: A common clinical manifestation of bacterial meningitis is a positive Kernig sign, which indicates meningeal irritation. Kernig sign is elicited when the leg is bent at the hip and knee at 90-degree angles, and pain and resistance are felt with extension at the knee due to inflamed meninges. Options A, B, and C are not typically associated with bacterial meningitis. A rash is more commonly seen in viral illnesses, photophobia can be present but is not specific to bacterial meningitis, and jaundice is not a typical clinical manifestation of this condition.

Correct Answer: B

Rationale: During a vaso-occlusive crisis in sickle cell anemia, ensuring adequate hydration is crucial because it helps to reduce the viscosity of the blood and prevent further sickling of the cells. Administering oxygen may be necessary in some cases to improve tissue oxygenation, but hydration is the priority to prevent complications. Monitoring vital signs is important, but hydration takes precedence during a vaso-occlusive crisis. Administering pain medication is important for pain management but does not address the underlying issue of vaso-occlusion.

Correct Answer: A

Rationale: The nurse should suspect measles based on the symptoms described, including the presence of Koplik spots (small, red spots with blue-white centers in the mouth). Measles typically presents with fever, irritability, runny nose, and a rash that begins on the face and spreads downward. Chickenpox (choice B) presents with vesicular lesions in different stages of healing and usually starts on the trunk. Fifth disease (choice C) presents with a 'slapped cheek' rash on the face and can cause joint pain. Scarlet fever (choice D) is characterized by a sandpaper-like rash, fever, and strawberry tongue.

Correct Answer: B

Rationale: The correct answer is B: Antifungals. Candidal diaper rash is caused by a yeast infection and is best treated with antifungal agents. Corticosteroids (choice A) may worsen fungal infections by suppressing the immune response. Antibiotics (choice C) are used to treat bacterial infections, not fungal infections like candidal diaper rash. Retinoids (choice D) are not typically used to treat candidal diaper rash in infants; they are more commonly used for dermatological conditions like acne.
