A nurse in a provider's office is collecting baseline preoperative data from a 5-month-old infant who has coarctation of the aorta. Which of the following locations should the nurse palpate to check for the presence of the infant's femoral pulse? (You will find hot spots to select in the artwork below. Select only the hot spot that corresponds to your answer).

Answer and Explanation

The Correct Answer is "{\"xRanges\":[111.828125,122.828125],\"yRanges\":[106.5,117.5]}"

A: Location A is near the infant’s foot, specifically around the ankle. This area is where the posterior tibial or dorsalis pedis pulse would be palpated, not the femoral pulse. These pulses are important for assessing peripheral circulation but are not the primary site for evaluating coarctation of the aorta, which requires checking central pulses like the femoral.

B: Location B is at the upper inner thigh, near the groin, where the femoral artery passes close to the skin surface. This is the correct site for palpating the femoral pulse in an infant. In conditions like coarctation of the aorta, comparing the strength of the brachial and femoral pulses is crucial to detect differences in blood flow between the upper and lower body.

C: Location C is on the upper arm, near the shoulder area, which corresponds to the location for checking the brachial pulse. The brachial pulse is commonly used in infants to assess heart rate, especially during resuscitation efforts. However, it is not the site for assessing femoral pulse strength, which is needed when evaluating for coarctation of the aorta.

Correct Answer is C

Explanation

A. "Check the water temperature with your finger": Checking water temperature with a finger is unreliable because fingers may tolerate higher temperatures without discomfort. It is recommended to use the inside of the wrist or a thermometer to ensure the water is warm but not hot, typically around 100°F (37.8°C), to prevent burns.

B. "Hold your baby under running water when washing his hair": Holding a newborn under running water is unsafe because it can cause sudden chilling, difficulty breathing, or even slipping. Instead, caregivers should use a damp, warm washcloth or gently pour water over the baby's head while securely supporting it.

C. "Cleanse the eyes from the inner canthus outward": Cleaning from the inner to the outer canthus is correct technique because it prevents introducing contaminants into the tear duct. This motion also minimizes the spread of bacteria, reducing the risk of eye infections in the delicate eyes of a newborn.

D. "Set the water heater to 125.6 degrees Fahrenheit": A water heater set to 125.6°F presents a high risk of scald burns in infants. Safety guidelines recommend setting the water heater to no higher than 120°F (48.9°C) to reduce the risk of accidental burns during bathing or household water use.

A. Epinephrine relaxes the bronchioles and counteracts the effect of histamine B. Epinephrine should be given along with a beta blocker. C. Epinephrine should be administered intranasally D. Epinephrine causes a decrease in blood pressure

Correct Answer is A

Explanation

A. Epinephrine relaxes the bronchioles and counteracts the effect of histamine: Epinephrine is the first-line treatment for anaphylaxis because it rapidly relaxes bronchial smooth muscles, reducing airway constriction, and counteracts histamine's effects, which include vasodilation, edema, and hypotension. This helps restore breathing and circulation.

B. Epinephrine should be given along with a beta blocker: Administering epinephrine with a beta blocker is dangerous because beta blockers can reduce the effectiveness of epinephrine and may worsen bronchospasm. Beta blockers are not recommended during acute management of anaphylaxis.

C. Epinephrine should be administered intranasally: Epinephrine is typically administered intramuscularly (IM), usually into the thigh, during anaphylactic emergencies for rapid absorption. Intranasal administration is not effective for treating life-threatening systemic allergic reactions.

D. Epinephrine causes a decrease in blood pressure: Epinephrine actually increases blood pressure by causing vasoconstriction. This counters the dangerous hypotension that occurs during anaphylaxis, helping to stabilize cardiovascular function quickly.
