A nurse is reviewing the laboratory results of a client who has bulimia nervosa. The nurse should notify the provider of which of the following results?
Potassium 3.2 mEq/L
WBC 5,200/mm3
Hgb 14 g/dL
Magnesium 1.6 mEq/L
The Correct Answer is A
Low potassium levels, known as hypokalemia, can be a significant concern in individuals with bulimia nervosa due to the frequent purging behaviors associated with the condition. Purging, such as self-induced vomiting or misuse of laxatives or diuretics, can lead to excessive loss of potassium from the body. Hypokalemia can have serious consequences, including cardiac arrhythmias, muscle weakness, fatigue, and even life-threatening complications.
The normal range for potassium is typically around 3.5-5.0 mEq/L. With a potassium level of 3.2 mEq/L falling below the normal range, it indicates a low potassium level and requires prompt attention.
The other laboratory results mentioned in the question are within normal ranges:
● A WBC (white blood cell) count of 5,200/mm3 falls within the normal range (typically between 4,500 and 11,000/mm3) and indicates a normal white blood cell count.
● An Hgb (hemoglobin) level of 14 g/dL falls within the normal range (typically between 12 and 16 g/dL) and indicates a normal hemoglobin level.
● A magnesium level of 1.6 mEq/L, although slightly low, is still within the normal range (typically between 1.5 and 2.5 mEq/L). The nurse should monitor it closely and assess for symptoms associated with hypomagnesemia. If the client's symptoms or other clinical indications suggest a significant magnesium imbalance, the healthcare provider should be notified.

Correct Answer is A
Explanation
Iron deficiency can have various manifestations, but one of the significant effects is its impact on cognitive function. Iron is essential for the proper functioning of the brain and nervous system. In children, iron deficiency can lead to lowered intellectual performance, including difficulties with concentration, learning, memory, and problem-solving skills. It can also affect overall cognitive development and academic performance.
The other options listed are not typically associated with iron deficiency:
"Elevated temperature": Elevated temperature or fever is not a direct manifestation of iron deficiency. Fever is commonly associated with infections, inflammatory conditions, or other illnesses, but not specifically with iron deficiency.
"Decreased sleeping time": While iron deficiency can cause various symptoms, changes in sleep patterns, such as decreased sleeping time, are not a typical manifestation. Iron deficiency may cause fatigue and general weakness, which could potentially impact sleep quality and duration, but it is not directly associated with decreased sleeping time.
"Increased risk of infection": Iron deficiency can affect the immune system, making individuals more susceptible to infections. However, an increased risk of infection is a consequence of impaired immune function rather than a direct manifestation of iron deficiency itself.
Correct Answer is A
Explanation
Bananas: Bananas are a suitable choice for a client taking digoxin and furosemide. Digoxin is a medication commonly prescribed for heart failure and certain heart rhythm disorders, and maintaining adequate potassium levels is important while taking this medication. Bananas are a good source of potassium and can help prevent or correct low potassium levels (hypokalemia), which can be a potential side effect of both digoxin and furosemide.
Green beans: Green beans can be included in the client's diet when taking digoxin and furosemide. While they are a healthy vegetable choice, they do not have a direct impact on the potassium levels affected by these medications.
Blueberries: Blueberries are a nutritious fruit choice, but they do not have a specific relevance to the client's medication regimen of digoxin and furosemide. They can be part of a balanced diet but are not specifically recommended or contraindicated in this context.
Cucumbers: Cucumbers are a refreshing vegetable choice, but they do not have a direct impact on the potassium levels affected by digoxin and furosemide. While maintaining hydration is important, other foods would be more relevant for addressing potassium needs.
