Explanation

Morning sickness, or Nausea and Vomiting of Pregnancy (NVP), is a common condition in early pregnancy.
Symptoms typically begin around the 4th to 6th week, peak around the 9th week, and resolve by the end of the first trimester (12-14 weeks).
The end of the 3rd month of pregnancy corresponds to approximately 12 weeks, which is the most common time for morning sickness to disappear.
This resolution is linked to the decline in human chorionic gonadotropin (hCG) hormone levels after they peak late in the first trimester.

Option A: At the end of the first month (4 weeks), morning sickness symptoms are typically just beginning, not disappearing.
Option B: The end of the second month (8 weeks) is often when the symptoms of morning sickness are at their most intense or are peaking, not resolving.
Option D: While a small percentage of women may experience nausea and vomiting into the second trimester, it is not the typical duration. Symptoms persisting this long, especially if severe, may indicate hyperemesis gravidarum, a more serious condition.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Timeline and resolution of morning sickness in pregnancy as background academic context rather than a clinical decision trigger.
Nurses play a key role in educating pregnant women that morning sickness is usually a normal part of early pregnancy and typically resolves on its own.
It is crucial for nurses to differentiate between normal morning sickness and hyperemesis gravidarum. Key warning signs to watch for include significant weight loss, signs of dehydration (dark urine, dizziness), and inability to keep down any fluids.
Management strategies for mild NVP include dietary advice (small, frequent meals; avoiding trigger foods), which nurses can teach patients.

How to Approach the Question

First, identify the core concept of the question, which is the typical duration of 'morning sickness' in pregnancy.
Recall the physiological timeline of early pregnancy. Remember that morning sickness is most common in the first trimester.
Relate the trimesters to months: the first trimester ends at approximately 12-14 weeks, which is the end of the 3rd month.
Consider the hormonal basis: Morning sickness is linked to rising hCG levels, which peak late in the first trimester and then decline. The symptoms follow this hormonal pattern.
Evaluate the options based on this timeline: 1 month is too early (onset), 2 months is too early (peak), 3 months aligns with the end of the first trimester (resolution), and 5 months is atypically long.
Select the option that best matches the end of the first trimester.
