A nurse is obtaining vital signs from a 2-month-old infant. The infant's heart rate is 190/min and his temperature is 40° C (104° F). The father asks the nurse why the infant's heart is beating so fast. Which of the following responses by the nurse is appropriate?
"This is within the expected range for your baby."
"The fever is causing an increase in your baby's heart rate."
"As your baby begins to fall asleep. his heart rate will decrease."
"Your baby's heart is beating fast in an attempt to cool down his body."
The Correct Answer is B
In this scenario, the infant has a heart rate of 190/min and a fever of 40°C (104°F). Fever in infants can cause an increase in heart rate, which is a normal physiological response to elevated body temperature. Fever is the body's way of responding to an infection or illness, and it triggers various physiological changes, including an increase in heart rate. This helps the body to circulate blood and deliver immune cells to fight off the infection.
The other options are not accurate or relevant to the infant's current condition:
A. "This is within the expected range for your baby." - A heart rate of 190/min is above the normal expected range for a 2-month-old infant, which is typically between 120 to 160 beats per minute. This response would not address the elevated heart rate and fever.
C. "As your baby begins to fall asleep, his heart rate will decrease." - While heart rate may decrease during sleep, it does not explain the elevated heart rate and fever observed in this situation.
D. "Your baby's heart is beating fast in an attempt to cool down his body." - While tachycardia (fast heart rate) can be associated with increased metabolic demands during fever, the main reason for the increased heart rate in this case is the fever itself, not the body's attempt to cool down. Fever is a response to infection or illness and can cause an increase in heart rate as part of the body's normal immune response.

Correct Answer is B
Explanation
The nurse should clarify the prescription to administer sodium biphosphate/sodium phosphate because it is a laxative and is contraindicated in a child with suspected appendicitis. The use of laxatives or enemas can potentially worsen the condition by increasing the risk of perforation or rupture of the inflamed appendix.
A. Monitoring oral temperature every 4 hours is important to assess for signs of infection or worsening condition.
C. Maintaining NPO status is essential to avoid stimulating the digestive system and to prepare for possible surgery.
D. Medicating the client for pain every 4 hours as needed is appropriate to manage pain and provide comfort while the child awaits further evaluation or treatment.
Remember, it's crucial to avoid the use of laxatives, enemas, or any other interventions that can potentially aggravate the inflamed appendix in a child with suspected appendicitis.
Correct Answer is D
Explanation
The nurse's priority assessment finding in an adolescent who experienced blunt trauma to the abdomen is low blood pressure (hypotension). Hypotension could indicate significant internal bleeding or hemorrhage, which is a life-threatening condition and requires immediate attention. The decreased blood pressure may be a sign of shock, and prompt intervention is needed to stabilize the client's condition and prevent further deterioration.
While all the other findings (respiratory rate, abdominal pain, and heart rate) are important and should be assessed and monitored, blood pressure is the most critical in this situation due to its potential association with severe internal injuries and the risk of hypovolemic shock.
