Practice questions
- In the cited expert perspective on nutritional anemia beyond iron, which group was classified as having strong evidence for roles in anemia development, erythropoiesis, or iron metabolism?
- Which set of micronutrients was categorized as having moderate evidence for roles in nutritional anemia, erythropoiesis, or iron metabolism in the expert perspective?
- Which pair did the expert perspective place in the potential or emerging-evidence category for roles in nutritional anemia?
- A learner states that nutritional anemia can be attributed to iron deficiency alone because iron is the presumed major nutritional cause. Which response best reflects the cited expert perspective?
- Which statement best interprets the review's use of the label “strong evidence” for folate, vitamin B12, and vitamin A?
- A question asks which nutrient the cited expert perspective classified as having moderate, rather than strong or potential/emerging, evidence in nutritional anemia. Which is the best answer?
- Which conclusion is most justified by the expert perspective's ranking of ten micronutrients?
- In a 2023–2025 TriNetX study of patients with obesity, which deficiency was reported as the most prevalent form of the double burden of malnutrition?
- In the TriNetX study of patients with obesity, what was the reported prevalence of protein deficiency among the highlighted double-burden categories?
- Which of the following correctly gives the reported prevalence of calcium deficiency in the TriNetX obesity cohort?
- Which age group was specifically reported to have higher incidence rates of protein, calcium, magnesium, and vitamin B12 deficiencies in the TriNetX study?
- Among vitamin D deficiency, vitamin B12 deficiency, and prior underweight status, which exposure had the highest reported median hazard ratio for metabolic disease burden in the TriNetX study?
- A report of an elevated median hazard ratio for vitamin D deficiency in the TriNetX cohort is best interpreted as:
- Which statement best describes the comparison made in the TriNetX study of nutritional deficiencies and obesity?
- Which combination of outcomes was included in the TriNetX study's assessment of metabolic disease burden among patients with obesity and nutritional deficiencies?
- In the retrospective presurgical cohort spanning BMI 30 to 91 kg/m², which micronutrients were reported to decline progressively with increasing BMI?
- In the presurgical severe-obesity cohort, vitamin D concentration was reported to correlate inversely with which metabolic measure?
- Which subgroup in the presurgical cohort had the most pronounced vitamin B6 depletion?
- Which statement about vitamin D across metabolic subgroups in the presurgical severe-obesity cohort is supported by the abstract?
- In the random-forest analysis of the severe-obesity presurgical cohort, which variable was identified among the strongest discriminators of type 2 diabetes?
- Which pair of body-composition measures was reported among the strongest discriminators of high BMI in the presurgical cohort's random-forest analysis?
- Which design limitation is most important when interpreting the micronutrient findings from the severe-obesity presurgical cohort?
- An investigator proposes targeted micronutrient supplementation solely on the basis of the presurgical cohort's observed associations. Which response best reflects the authors' conclusion?
- In the claims analysis of pediatric GLP-1 receptor agonist users, what proportion had at least one recorded nutritional deficiency or deficiency-related complication within one year?
- Which deficiency was most frequently recorded within one year among the pediatric GLP-1 receptor agonist users in the claims study?
- What proportion of pediatric GLP-1 receptor agonist users in the claims study had a nutrition therapy or counseling visit within 180 days?
- In the pediatric GLP-1 receptor agonist claims study, patients with a nutrition therapy or counseling visit had more recorded deficiency diagnoses or related complications than patients without such a visit. What is the most appropriate interpretation?
- Which study population was analyzed in the pediatric GLP-1 receptor agonist claims report?
- Which conclusion is most consistent with the pediatric GLP-1 receptor agonist claims study?
