A nurse is preparing to administer recommended immunizations to an 11-year-old child who is up-to-date with current immunizations. Which of the following immunizations should the nurse plan to administer?

Choice A rationale:
Extremities warm to the touch. This manifestation is not indicative of decreased cardiac output. Warm extremities suggest adequate peripheral perfusion and circulation. In a child with decreased cardiac output, the body might attempt to shunt blood away from the extremities to prioritize vital organs, leading to cooler extremities.
Choice B rationale:
Capillary refill 2 seconds. A capillary refill time of 2 seconds is within the normal range for a preschool-aged child. This quick capillary refill suggests adequate circulation and is not a sign of decreased cardiac output. Prolonged capillary refill time might be indicative of poor peripheral perfusion.
Choice C rationale:
Blood pressure 112/66 mm Hg. While a blood pressure of 112/66 mm Hg might be within the normal range for a preschooler, it is not the most reliable indicator of decreased cardiac output. Blood pressure can be influenced by various factors, and a seemingly normal blood pressure does not rule out decreased cardiac output if other manifestations are present.
Choice D rationale:
Diminished pulses. This is the correct choice. Diminished or weak pulses are indicative of decreased cardiac output. Inadequate blood volume being pumped by the heart can lead to reduced peripheral perfusion, resulting in diminished pulses. This sign is important in assessing the child's cardiovascular status postoperatively, especially after a corrective procedure for tetralogy of Fallot.

The correct answer is Choice D.

Choice A rationale: Administering an oral corticosteroid is not the first action the nurse should take. Corticosteroids are used to reduce inflammation and itching caused by poison ivy. However, they are usually prescribed if the symptoms are severe or if the rash covers a large area of the body. It’s important to note that corticosteroids can have side effects, especially when used for a long time, so they should be used under the supervision of a healthcare provider.

Choice B rationale: Applying calamine lotion to the affected area can help soothe the skin and relieve itching caused by poison ivy. However, this is not the first action the nurse should take. The first step is to remove the oil from the skin that causes the allergic reaction. Calamine lotion can be applied after the area has been thoroughly washed.

Choice C rationale: Instructing the parent to give the child an oatmeal bath twice daily can help soothe the skin and relieve itching. However, this is not the first action the nurse should take. Similar to calamine lotion, an oatmeal bath can be beneficial after the area has been thoroughly washed to remove the oil from the skin.

Choice D rationale: The first action the nurse should take when caring for a child exposed to poison ivy is to flush the area with cold, running water. This helps to remove the oil (urushiol) from the skin that causes the allergic reaction. It’s important to do this as soon as possible after exposure to help prevent the spread of the oil to other areas of the body or to other people. After flushing the area, the nurse can then apply calamine lotion or recommend an oatmeal bath to help soothe the skin and relieve itching.
