A nurse is preparing to administer nasogastric tube feedings to a 2-month-old infant. Which of the following actions should the nurse plan to take?

Choice A rationale:
Apply cold packs to the lower abdomen. This is the correct answer because applying cold packs to the lower abdomen can help alleviate dysmenorrhea (painful menstrual cramps). Cold therapy helps to constrict blood vessels, reducing blood flow to the area and thus reducing pain. It's a non-pharmacological approach to managing menstrual cramps.
Choice B rationale:
Increase daily intake of fat. Increasing fat intake is not a recommended approach for managing dysmenorrhea. Balanced nutrition is important, but increasing fat intake is unlikely to significantly impact menstrual cramps. Other strategies are more effective.
Choice C rationale:
Massage the lower back area. Massaging the lower back can help with muscle relaxation and may provide some relief, but it is not as effective as applying cold packs to the lower abdomen for dysmenorrhea. Cold packs specifically target blood flow reduction to the area of pain.
Choice D rationale:
Limit physical activity. While it's generally a good idea to avoid strenuous physical activity during periods of intense pain, limiting physical activity alone is not the most effective strategy for managing dysmenorrhea. Cold packs and other interventions are more likely to provide relief.

Choice A rationale:
Edema. Edema, the accumulation of fluid in the tissues, is not the primary indicator of compartment syndrome. While edema can occur due to various reasons, it's not specific to compartment syndrome. Compartment syndrome primarily involves increased pressure within a closed space (muscle compartment), which can compromise blood circulation and nerve function.
Choice B rationale:
Mottling. Mottling refers to a patchy, bluish discoloration of the skin that occurs due to poor blood circulation and is often seen in critically ill patients. While it might indicate circulatory issues, it's not a direct sign of compartment syndrome. Compartment syndrome is more closely associated with symptoms such as severe pain, numbness, and decreased or absent pulses.
Choice C rationale:
Urticaria. Urticaria, also known as hives, is a skin rash characterized by raised, itchy, and red or white welts. It is typically caused by an allergic reaction or other factors such as medications. Urticaria is unrelated to compartment syndrome, which involves the compression of nerves and blood vessels within a closed anatomical compartment, leading to ischemia and potential tissue damage.
Choice D rationale:
Pulselessness. Pulselessness is a critical sign that the nurse should monitor when conducting a circulatory check for compartment syndrome. Compartment syndrome occurs when there is increased pressure within a confined space (muscle compartment), leading to compromised blood flow and oxygen delivery to the tissues. The lack of a palpable pulse in the affected area suggests that blood flow is severely compromised. This is a late sign of compartment syndrome and requires immediate intervention to prevent tissue necrosis and long-term complications.
