## 문제

A nurse is caring for a 25-year-old client at 12 weeks gestation who has been admitted with hyperemesis gravidarum. The client has lost 10 pounds since her last prenatal visit and reports vomiting 8-10 times daily for the past week. Which nursing intervention should be the priority?

## 보기

1. Encourage small, frequent meals with dry crackers
2. Administer prescribed antiemetic medication
3. Provide emotional support and reassurance
4. Initiate IV fluid replacement therapy **✔ 정답**

**정답: 4**

## 해설

IV fluid replacement is priority for severe hyperemesis with significant weight loss and frequent vomiting to correct dehydration and electrolyte imbalances. Other interventions (antiemetics, small meals, emotional support) are important but secondary to fluid resuscitation.

Understanding Hyperemesis Gravidarum and Clinical Priority Setting

When a client presents with hyperemesis gravidarum (HG), the pathophysiology extends far beyond typical morning sickness. HG involves severe, persistent nausea and vomiting leading to dehydration, electrolyte imbalances, and significant nutritional deficits. In this scenario, the client's report of vomiting 8-10 times daily and a weight loss of 10 pounds signals a critical loss of fluid volume. The immediate physiological threat is hypovolemia, which can lead to tachycardia, hypotension, and prerenal failure. While antiemetics, dietary modifications, and emotional support are all essential components of a comprehensive care plan, they are secondary to stabilizing the client's hemodynamic status. The body cannot effectively utilize oral medications or nutrients if the gastrointestinal tract is in a state of severe spasm and the vascular compartment is depleted. Furthermore, research indicates that severe NVP and HG are associated with adverse pregnancy outcomes, and inadequate gestational weight gain (GWG) mediates some of these risks [2]. However, the most immediate danger is the current fluid and electrolyte deficit. Therefore, the priority nursing intervention is to restore intravascular volume and correct electrolyte disturbances through IV fluid replacement therapy. This foundational step halts the cycle of dehydration, improves tissue perfusion, and creates a physiological environment where subsequent interventions, such as antiemetics, can be effective. Delaying fluid resuscitation to try oral intake or provide counseling first could lead to clinical deterioration, including rare but serious complications like Wernicke encephalopathy due to thiamine deficiency, a neurological emergency documented in cases of severe HG [4].References (research sources)

Clinical Priority for Hyperemesis Gravidarum

When a client presents with severe hyperemesis gravidarum (HG), the immediate nursing priority is to stabilize the patient's hemodynamic status. The reported weight loss and frequent vomiting indicate significant fluid volume deficit. The first step is always to initiate IV fluid replacement therapy to correct hypovolemia and electrolyte disturbances. This restores tissue perfusion and creates a stable physiological environment, allowing subsequent interventions like antiemetics or dietary changes to be effective.

**Assessment:** Monitor vital signs for signs of hypovolemia (tachycardia, hypotension), daily weight, strict intake and output, and urine specific gravity.

**Intervention Sequence:** 1. Initiate IV access and administer prescribed isotonic fluids (e.g., Lactated Ringer's or Normal Saline) with electrolyte replacement as needed. 2. Administer prescribed antiemetics parenterally (IV, IM, or rectal) initially, as the oral route is unreliable. 3. Once vomiting is controlled, slowly reintroduce oral intake with small, frequent, bland meals.

**Safety:** Maintain NPO status until vomiting is controlled to prevent aspiration. Implement seizure precautions if severe hyponatremia is suspected due to excessive fluid loss.

## 핵심 개념

- **Hyperemesis Gravidarum** — Severe, persistent nausea and vomiting during pregnancy leading to dehydration, electrolyte imbalances, and weight loss greater than 5% of pre-pregnancy body weight.
- **Hypovolemia** — A state of decreased intravascular blood volume, often caused by fluid loss from vomiting, leading to tachycardia, hypotension, and decreased organ perfusion.
- **Maslow's Hierarchy of Needs** — A psychological framework used in nursing to prioritize care, where physiological needs such as fluid balance and oxygenation must be met before safety, love, or esteem needs.
