Hyperemesis gravidarum (HG) is a severe form of morning sickness that affects pregnant women, characterized by persistent and debilitating nausea and vomiting. Unlike typical morning sickness, HG can lead to dehydration, weight loss, electrolyte imbalances, and nutritional deficiencies, posing risks to both the mother and the developing fetus. While the exact etiology of hyperemesis gravidarum is not fully understood, it is largely attributed to the significant hormonal shifts during early pregnancy, particularly the rapid increase in human chorionic gonadotropin (hCG) and estrogen levels. Gastroesophageal reflux disease (GERD) may also exacerbate nausea in pregnant women, contributing to HG. A familial predisposition also appears to increase a woman’s likelihood of developing this condition.
The symptoms of hyperemesis gravidarum typically manifest during the first trimester and can include:
- Persistent nausea and severe vomiting
- Vomiting frequency exceeding 3-4 times daily
- Significant weight loss, greater than 5% of pre-pregnancy weight
- Dizziness and lightheadedness
- Dehydration
- Headaches
- Fainting
Diagnosis of hyperemesis gravidarum is usually based on a thorough physical examination and medical history. Laboratory tests, including a complete blood count, electrolyte assessments, and urine ketone analysis, are crucial to evaluate the severity of dehydration and metabolic disturbances.
In this article, we will explore nursing diagnoses and develop comprehensive nursing care plans for hyperemesis gravidarum, focusing on addressing the key challenges posed by this condition.
Nursing Process in Hyperemesis Gravidarum
The primary focus of nursing care for patients with hyperemesis gravidarum is to accurately assess the severity of nausea and vomiting, evaluate the degree of dehydration, and determine the extent of weight loss. Nursing interventions are aimed at alleviating nausea and vomiting through medication administration, correcting fluid and electrolyte imbalances with intravenous therapy, and providing crucial patient education to facilitate home management and prevent complications. Effective nursing care plans are essential for guiding interventions and achieving both short-term symptom relief and long-term management goals.
Nursing Care Plans for Hyperemesis Gravidarum
Nursing care plans are developed based on identified nursing diagnoses to prioritize assessments and interventions. Below are examples of nursing care plans for hyperemesis gravidarum, addressing common nursing diagnoses.
Acute Pain
Persistent and severe nausea and vomiting associated with hyperemesis gravidarum can often be accompanied by abdominal pain, contributing to patient discomfort.
Nursing Diagnosis: Acute Pain
Related Factors:
- Disease process of hyperemesis gravidarum
- Hormonal imbalances of pregnancy
- Persistent nausea and vomiting
- Potential constipation
Evidenced by:
- Changes in appetite
- Reports of nausea and vomiting
- Reports of abdominal pain
- Distraction behaviors
- Expressive pain behaviors (e.g., groaning, crying)
- Facial grimacing or pain expressions
- Guarding of the abdomen
- Feelings of hopelessness related to pain
- Adopting positions to minimize pain
- Protective behaviors
Desired Outcomes:
- Patient will report a reduction in pain and improved management of nausea and vomiting symptoms.
- Patient will implement strategies to alleviate abdominal discomfort, nausea, and vomiting effectively.
Nursing Assessments:
1. Conduct a comprehensive pain assessment.
Abdominal pain in hyperemesis gravidarum can manifest as intermittent discomfort in the upper mid-abdominal region, alongside nausea and vomiting. It is crucial to differentiate this pain from more serious symptoms. Sharp, stabbing pain, right upper quadrant (RUQ) pain, or cramping accompanied by vaginal spotting may indicate other underlying conditions requiring immediate medical evaluation.
2. Evaluate the patient’s past pain experiences and pain management strategies.
Understanding the patient’s previous experiences with pain and effective pain relief methods can inform the development of a personalized and effective pain management plan for hyperemesis gravidarum.
Nursing Interventions:
1. Encourage small, frequent meals of bland foods.
For patients with hyperemesis gravidarum, consuming small, frequent meals consisting of bland, dry foods like toast and crackers can help soothe the gastrointestinal system and reduce nausea, vomiting, and associated abdominal pain.
2. Advise the patient to avoid greasy and spicy foods.
Spicy and greasy foods can exacerbate gastrointestinal upset and intensify nausea, vomiting, and abdominal pain in individuals with hyperemesis gravidarum. Dietary modifications are crucial.
3. Administer prescribed medications as indicated.
The combination of over-the-counter pyridoxine (vitamin B6) and doxylamine (an antihistamine) has been shown to be effective in managing nausea during pregnancy and may be prescribed to alleviate pain indirectly by reducing nausea and vomiting.
4. Consider ultrasound or other imaging if severe abdominal pain is present.
In cases of severe abdominal pain, particularly in the RUQ, diagnostic imaging such as ultrasound is essential to rule out other potential causes like appendicitis or gallstones, ensuring prompt and appropriate medical intervention.
5. Promote non-pharmacological pain relief techniques.
Non-pharmacological interventions, including relaxation techniques, massage, guided imagery, and the application of heat, can be valuable adjuncts in reducing abdominal pain and enhancing patient comfort.
Deficient Fluid Volume
The hallmark of hyperemesis gravidarum is excessive nausea and vomiting, which frequently leads to significant fluid loss, dehydration, and subsequent electrolyte imbalances.
Nursing Diagnosis: Deficient Fluid Volume
Related Factors:
- Excessive nausea and vomiting
- Inadequate oral fluid and food intake
- Increased gastric secretions associated with vomiting
- Disease process of hyperemesis gravidarum
Evidenced by:
- Reports of thirst
- Weight loss
- Dry skin
- Decreased skin turgor
- Dry mucous membranes
- Elevated body temperature
- Decreased blood pressure (hypotension)
- Increased heart rate (tachycardia)
- Reduced urine output
- Dizziness and fainting episodes
- Altered mental status or confusion
- Generalized weakness
Desired Outcomes:
- Patient will maintain adequate hydration, as evidenced by urine output within normal limits for pregnancy.
- Patient will report the absence of dizziness, weakness, and fainting episodes.
Nursing Assessments:
1. Meticulously monitor fluid intake and output.
Patients with hyperemesis gravidarum often experience an inability to retain oral intake. Rigorous monitoring of all intake (oral and intravenous) and output (vomiting, urine) is critical because dehydration can develop rapidly and severely.
2. Regularly assess for clinical signs of dehydration.
Recognizing the signs of dehydration, such as dry skin, dry mucous membranes, poor skin turgor, decreased blood pressure, tachycardia, and fever, is essential for prompt intervention and management of fluid volume deficit.
Nursing Interventions:

1. Educate the patient about the signs and symptoms of hyperemesis gravidarum.
While the exact cause remains unknown, educating patients about the presumed hormonal etiology and the importance of recognizing and managing signs and symptoms, particularly fluid loss, is vital for preventing complications.
2. Employ a patient-centered approach to facilitate learning and engagement.
Utilize diverse teaching methods to accommodate individual learning preferences. Incorporate printed materials, reliable online resources, and verbal instruction to cater to various learning styles and ensure effective knowledge transfer.
3. Request verbal feedback to confirm understanding (teach-back method).
To ensure comprehension, ask the patient to reiterate the key information in their own words. Specifically, they should be able to explain the signs and symptoms of dehydration and understand when to seek medical attention.
4. Refer the patient to relevant support and community resources.
Peer support groups can offer invaluable emotional and practical support. Connecting patients with other women who have experienced hyperemesis gravidarum can reduce feelings of isolation and provide helpful coping strategies.
Imbalanced Nutrition: Less Than Body Requirements
Hyperemesis gravidarum frequently leads to inadequate nutritional intake due to persistent vomiting, resulting in weight loss, malnutrition, and potential harm to both maternal and fetal health.
Nursing Diagnosis: Imbalanced Nutrition: Less Than Body Requirements
Related Factors:
- Persistent nausea and vomiting
- Disease process of hyperemesis gravidarum
- Altered taste perceptions or food aversions
Evidenced by:
- Muscle weakness and fatigue
- Signs of malnutrition
- Unintended weight loss
- Dehydration
- Fatigue and lethargy
- Dietary intake below recommended daily allowances
- Hypoglycemia
- Pale mucous membranes
- Dry skin
- Poor fetal growth or intrauterine growth restriction (IUGR)
Desired Outcomes:
- Patient will demonstrate progressive weight gain and a decrease in the severity of nausea and vomiting episodes.
- Patient will be able to increase oral food and fluid intake, identify triggers for nausea, and implement effective strategies to alleviate nausea and vomiting.
Nursing Assessments:
1. Assess fetal well-being and growth.
In cases requiring inpatient management, continuous fetal monitoring may be indicated to assess fetal heart rate and overall fetal status, ensuring early detection of any distress.
2. Monitor maternal weight and weight trends.
Significant and prolonged nausea and vomiting can cause malnutrition, dehydration, and weight loss. Documenting and monitoring maternal weight, particularly a weight loss exceeding 5% of pre-pregnancy weight, is a key diagnostic indicator and guides nutritional interventions.
Nursing Interventions:
1. Administer parenteral nutrition as clinically indicated.
For patients with severe hyperemesis gravidarum who cannot tolerate oral or enteral nutrition, parenteral nutrition (IV feeding) may be necessary to provide essential nutrients and support maternal and fetal health.
2. Encourage small, frequent meals and snacks.
Consuming small, frequent meals can be more easily tolerated and less likely to trigger nausea and vomiting episodes compared to larger meals, facilitating improved nutritional intake.
3. Consult with a registered dietitian for nutritional guidance.
A registered dietitian can provide expert advice on meal planning and dietary modifications tailored to the specific nutritional needs of pregnant women with hyperemesis gravidarum, ensuring adequate nutrient intake despite dietary limitations.
4. Offer ginger-containing products and consider changing prenatal vitamins.
Ginger has demonstrated efficacy in reducing nausea and can be offered in forms like ginger chews or drinks. Switching prenatal vitamins to folic acid alone may also be beneficial, as some prenatal formulations can exacerbate nausea.
Nausea
Nausea is a primary symptom of hyperemesis gravidarum and, when severe and persistent, significantly impacts a pregnant woman’s quality of life and health.
Nursing Diagnosis: Nausea
Related Factors:
- Physiological changes of pregnancy
- Heightened sensitivity to sensory stimuli
- Rapid increase in pregnancy hormones
- Multiple gestation pregnancies (twins, triplets, etc.)
- Genetic predisposition to hyperemesis gravidarum
Evidenced by:
- Food aversions
- Increased salivation (ptyalism)
- Reports of gagging sensations
- Unpleasant or sour taste in the mouth
- Increased frequency of swallowing
- Episodes of vomiting
Desired Outcomes:
- Patient will report a decrease in the frequency and severity of nausea and vomiting.
- Patient will demonstrate effective strategies to manage and alleviate nausea and vomiting.
- Patient will be able to tolerate small meals and maintain adequate fluid intake.
Nursing Assessments:
1. Assess for potential causes and triggers of nausea beyond pregnancy.
A thorough assessment to identify triggers and underlying causes of nausea, apart from pregnancy itself, is crucial for developing a targeted and effective treatment plan to prevent symptom escalation.
2. Inquire about a history of nausea outside of pregnancy.
Research suggests that women with a history of nausea and vomiting unrelated to pregnancy, such as motion sickness or migraine-associated nausea, may have an increased susceptibility to nausea and vomiting during pregnancy.
Nursing Interventions:
1. Minimize exposure to strong or unpleasant odors.
Pregnancy often heightens olfactory sensitivity, making pregnant women more susceptible to nausea triggered by strong or offensive smells. Eliminating these triggers is essential.
2. Promote non-pharmacological nausea management techniques.
Non-pharmacological approaches like meditation, distraction, music therapy, and deep breathing exercises can be effective in reducing nausea and vomiting and empowering patients with self-management strategies.
3. Administer antiemetic medications as prescribed.
Antiemetic medications are often necessary to provide relief from severe nausea and vomiting associated with hyperemesis gravidarum, improving patient comfort and enabling better oral intake.
4. Encourage acupressure at the P6 point (Neiguan).
Applying pressure to the P6 acupressure point on the inner wrist is believed to alleviate nausea. Acupressure bands are commercially available to facilitate consistent pressure application at this site.
