Pregnancy & nutritional deficiencies01 / 02

A 36-year-old woman, gravida 1, para 0, at 26 weeks' gestation comes to the physician for a prenatal visit. She says that she has been craving ice and paper products like toilet paper for the past 2 months. She carries a cup of ice with her wherever she goes and frequently chews on the ice. She does not take any medications. Physical examination shows dry, scaly lips and erythema of the corners of the mouth. Pelvic examination shows a uterus consistent in size with a 26-week gestation. Which of the following additional findings is most likely in this patient?

Before your first block

A few good
questions.

The goal is simple: make testing at home feel deliberate enough that exam day feels familiar.

Can I recreate testing conditions at home?

Yes—that is the heart of FREE 120. Use timed blocks, the exam-style interface, familiar navigation and review tools, and a quiet desk to rehearse the conditions you expect on test day. The site works on mobile, but a tablet or computer is strongly recommended for the closest exam and question-bank experience.

What will the analytics tell me after an exam?

See more than a final percentage: review correct, incorrect, omitted, and marked items; compare performance by content category and block; inspect pacing; and use answer-change patterns to find where your decision-making helped or hurt. Supported reports also separate marked answers by outcome, so you can see the percentage of marked questions that finished correct versus incorrect.

Can I review marked questions and changed answers?

Yes. Reopen marked items, review incorrect items as a group, and inspect answer changes—including moves from incorrect to correct and correct to incorrect. Those patterns help distinguish useful reconsideration from second-guessing, so your next block has a specific strategy instead of only a score goal.

How do I turn the report into a better next block?

Start with the weakest content categories, then compare accuracy with time spent, omitted items, marked-item outcomes, and answer-change direction. Build a focused subject block for the knowledge gap, or another timed mixed block when pacing and decision-making are the bigger issue.

Can I use timed and tutor modes?

Yes. Timed mode rehearses pacing and keeps answers hidden until review. Tutor mode lets you check the answer and explanation as you study. Available modes and timing follow the form or question bank you choose.

Can I practice by subject?

Use subject and system filters to build focused sessions, or combine available question banks for mixed custom practice. Your available sources depend on your account access.

Will my work follow me to another device?

Your account keeps saved blocks, answers, marks, notes, and review history together. Sign in on another device to continue your saved work. For a full exam simulation, use one stable tablet or computer from start to finish.

Is FREE 120 an official exam provider?

No. This is an independent educational simulator, not affiliated with or endorsed by official exam organizations or other study providers. Practice scores are not official exam results, and no outcome is guaranteed.
