A nurse is collecting data from a 1-week-old infant who is scheduled for a cardiac catheterization. Which of the following locations should the nurse palpate in order to identify the infant's point of maximal impulse? (You will find hot spots to select in the artwork below. Select only the hot spot that corresponds to your answer.)

A. Pinto beans: Pinto beans are a good source of protein, but they are not considered a complete protein. They lack some of the essential amino acids, although they can be paired with other foods (like rice) to form a complete protein.
B. Peanut butter: Peanut butter is a good source of protein, but like pinto beans, it is not a complete protein. It lacks some essential amino acids, and while it can be part of a balanced diet, it does not provide all the necessary amino acids on its own.
C. Eggs: Eggs are an excellent source of complete protein because they contain all nine essential amino acids that the body cannot produce on its own. They are considered one of the best sources of high-quality, complete protein.
D. Broccoli: While broccoli contains some protein, it is not a complete protein. It provides some essential amino acids, but not all nine, so it does not qualify as a complete protein source on its own.

Rationale:

• Insert a peripheral IV catheter: A peripheral IV catheter is essential for administering fluids and medications, which is critical for this adolescent, especially with the concern for bacterial meningitis.
• Place the adolescent on a cooling blanket: The adolescent has a high fever (39°C), which needs to be managed promptly to prevent further complications. A cooling blanket helps reduce the fever and manage the patient’s temperature.
• Administer IV acyclovir: Acyclovir is an antiviral medication typically used to treat viral infections such as herpes simplex virus or varicella-zoster virus, not bacterial meningitis. Given the CSF findings and suspected bacterial meningitis, acyclovir is not appropriate. Antibiotics like cefotaxime are indicated instead.
• Place on seizure precautions: Given the adolescent's symptoms (e.g., headache, photophobia, lethargy), the risk of seizures is elevated, especially if meningitis is suspected. Seizure precautions are important to prevent injury during a potential seizure.
• Keep adolescent flat in bed for 24 hr post lumbar puncture: After a lumbar puncture, keeping the adolescent flat in bed for 24 hours helps prevent post-lumbar puncture headaches and minimizes the risk of cerebrospinal fluid leaks or complications.
• Administer IV cefotaxime: IV cefotaxime is an appropriate antibiotic for treating bacterial meningitis. Given the abnormal CSF results (low glucose, high protein, elevated WBC), the adolescent is at high risk for bacterial meningitis, and IV cefotaxime is expected to be part of the treatment plan.
