Rationale: Chronic pancreatitis requires a low-fat diet to reduce stress on the pancreas. Broiled skinless chicken breast with brown rice is a suitable option as it is low in fat. Coffee with creamer and lettuce with sliced avocados are not recommended for individuals with chronic pancreatitis due to their fat content. Choosing options high in fat can exacerbate symptoms and increase the workload on the pancreas, worsening the condition.

Rationale: When measuring an infant's temperature, the most appropriate and non-invasive method is to place the tip of the thermometer under the center of the infant's axilla (armpit). This method is safe, quick, and comfortable for the infant. Inserting the probe into the rectum is invasive and not recommended for routine temperature measurement in infants. Inserting the thermometer in front of the infant's tongue is not a reliable method for measuring temperature. Pulling the pinna of the ear forward is a technique used for adults, not infants.

Correct Answer: A

Correct Answer: A
