A nurse is preparing to perform a heel stick using a spring-loaded automatic puncture device on a 1-week-old infant. In which of the following locations should the nurse puncture the infant's foot? (You will find hot spots to select in the artwork below. Select only the hot spot that corresponds to your answer.)
The Correct Answer is "{\"xRanges\":[93.828125,113.828125],\"yRanges\":[223,243]}"
A. Lateral aspect: The preferred location for performing a heel stick on a neonate is the lateral (outer) aspect of the heel, avoiding the central area and the arch of the foot. This area contains fewer nerve endings and less tissue, making it safer and less painful for the infant. It also minimizes the risk of injury to the underlying bones, blood vessels, and nerves.
B. Heel: The heel is not recommended as a puncture site because it contains fat, bone, and nerves, and puncturing the heel could cause injury or complications such as osteochondritis (bone infection). This site also carries a higher risk of injury to blood vessels and tendons.
C. Medial aspect: The medial (inner) aspect of the heel is also not recommended because it is near the medial plantar artery and nerves. Puncturing this area could result in damage to these structures, leading to complications. The lateral aspect is a safer, preferred location.

Correct Answer is D
Explanation
A. Increased blood pressure is typically not associated with dehydration. In fact, dehydration often causes hypotension or low blood pressure, especially in severe cases.
B. Distended jugular veins are usually a sign of fluid overload or heart failure, not dehydration. In dehydration, the veins may appear flat due to decreased fluid volume.
C. A flat anterior fontanel is generally expected in a well-hydrated child. A sunken fontanel would indicate dehydration in infants and young toddlers.
D. Increased pulse (tachycardia) is a common sign of dehydration. As the body loses fluid, the heart compensates by increasing the heart rate to maintain adequate perfusion of organs.
Correct Answer is D
Explanation
A. Using a dime-sized amount of the medication is not the recommended instruction for tretinoin. A small, pea-sized amount is typically advised to avoid irritation and overuse.
B. Tretinoin should be applied at night, not in the morning, as it increases sensitivity to sunlight and can cause irritation when exposed to sunlight.
C. It is generally recommended to wait 20-30 minutes after washing the face before applying tretinoin, not just 5 minutes. This allows the skin to dry completely, reducing irritation.
D. Tretinoin can cause skin sensitivity, making the skin more prone to sunburn. Using a sunscreen with SPF 15 or higher is crucial to protect the skin from harmful UV rays while using tretinoin.
