A nurse working in an outpatient mental health clinic is counseling an adolescent client recently diagnosed with bulimia nervosa.
Which nursing intervention has the highest priority?

Choice A rationale

Pancreatitis requires a slow reintroduction of nutrients starting with clear liquids that are low in fat and protein to avoid stimulating pancreatic enzyme secretion. Beef broth, gelatin, and apple juice provide hydration and simple carbohydrates without taxing the inflamed pancreas. Keeping fat intake near zero initially prevents the exacerbation of autodigestion and pain. Serum amylase levels (normal 30 to 110 U/L) and lipase (normal 0 to 160 U/L) should be monitored closely during this transition.

Choice B rationale

This meal is far too heavy in fats and complex proteins for a client recovering from acute pancreatitis. A hamburger patty, even if broiled, contains significant lipids that trigger cholecystokinin release, stimulating the pancreas to produce digestive enzymes. This could lead to a recurrence of severe epigastric pain and elevated serum lipase. High-fiber foods like peas and carrots may also be difficult to digest immediately after a 48 hour period of bowel rest and NPO status.

Choice C rationale

While gelatin and tea are appropriate clear liquids, oatmeal is a solid food containing fiber and complex carbohydrates. Introducing solids too early can lead to nausea and increased pancreatic workload. The goal of the first meal is to ensure the client can tolerate liquids before advancing to a full liquid or low-fat soft diet. Oatmeal requires more digestive effort than the pancreas may be ready to handle after a significant inflammatory event and prolonged fasting period.

Choice D rationale

This choice contains several items that are contraindicated for the initial post-NPO meal. Plain yogurt and vanilla ice cream contain dairy fats and proteins that strongly stimulate pancreatic activity. Vegetable soup may contain fats or large chunks of fiber that are inappropriate for the first stage of diet advancement. After 48 hours of NPO, the focus must remain on clear, non-fatty liquids to ensure the inflammation has subsided sufficiently to prevent a clinical relapse.

Choice A rationale

Fever assessment is a common nursing intervention used to identify inflammatory or infectious processes like pelvic inflammatory disease or appendicitis. Normal body temperature ranges from 97.0 F to 99.0 F. While a fever would provide diagnostic clues, it is not the most immediate priority when a client presents with severe localized pain and vaginal bleeding, which may indicate a life-threatening ruptured ectopic pregnancy requiring rapid surgical or medical intervention.

Choice B rationale

Identifying the timing of the last void helps the nurse assess bladder function and potential urinary tract involvement in abdominal pain. However, urinary status is secondary to the need for a focused reproductive history in this clinical scenario. While a full bladder could exacerbate discomfort or interfere with a physical examination, it does not provide the critical information needed to determine if the client is experiencing a gynecological emergency that compromises systemic stability.

Choice C rationale

Determining the date of the last menstrual period is the highest priority because it helps the nurse assess the possibility of pregnancy. Severe lower quadrant pain and vaginal bleeding in a woman of childbearing age are classic signs of an ectopic pregnancy. Rapid identification of pregnancy status allows the healthcare team to prioritize life-saving interventions, as rupture can lead to massive internal hemorrhage, hypovolemic shock, and rapid maternal physiological decline.

Choice D rationale

Asking about the last bowel movement helps evaluate gastrointestinal causes of abdominal pain, such as constipation or bowel obstruction. While gastrointestinal issues can cause lower quadrant distress, they are generally less acute than a suspected ruptured ectopic pregnancy. In an emergency setting, the nurse must first rule out the most lethal possibilities related to the client's specific symptoms of vaginal bleeding combined with severe localized pelvic pain before exploring digestive issues.
