Nursing Clinical Practice Guide
Clinical Scenario: You are a nurse in the OB triage. A patient at 9 weeks gestation is brought in by her partner. She appears fatigued, with dry lips and sunken eyes. She states, "I can't stop throwing up, not even water stays down. I'm so weak."
Nursing Intervention Strategy:
1. Assessment (ABCs first): Assess vital signs (tachycardia, orthostatic hypotension indicate dehydration). Perform a focused physical assessment: mucous membranes, skin turgor, capillary refill. Ask about weight change from pre-pregnancy. Priority: Obtain a urine sample to check for ketones and specific gravity.
2. Planning & Implementation: Anticipate orders for IV access and fluid resuscitation with normal saline or lactated Ringer's. Administer prescribed antiemetics (e.g., ondansetron IV). Key Point! If the patient appears malnourished or has been vomiting for an extended period, ensure thiamine is administered BEFORE starting dextrose-containing fluids. Initiate strict Intake & Output (I&O) monitoring.
3. Evaluation & Education: Monitor for resolution of ketonuria, improved urine output, and stabilization of vital signs. Once vomiting is controlled, advance diet slowly (clear liquids → bland foods). Educate on eating small, frequent, dry, high-carbohydrate, low-fat meals and avoiding triggers (strong smells).
Patient Safety and Precautions:
* Contraindication: Do not give dextrose IV before thiamine in a starved patient.
* Medication Caution: Monitor for side effects of antiemetics (e.g., sedation with promethazine, QT prolongation with ondansetron).
* Key Monitoring: Daily weights, strict I&O, electrolyte panels (especially potassium), and signs of worsening dehydration or nutritional deficit.
Nursing Procedure & Medication Flow
Procedure for Managing Suspected HG:
1. Triage Assessment (Vitals, Physical, Urinalysis for ketones).
2. Notify Provider of findings (weight loss >5%, ketonuria, dehydration).
3. Establish IV Access (large-bore catheter).
4. Administer Thiamine 100mg IV/IM (if indicated).
5. Initiate IV Fluid Therapy (e.g., 1-2 L NS over 2-4 hours) as ordered.
6. Administer IV Antiemetic as ordered.
7. Monitor Response (I&O, repeat urinalysis, symptom improvement).
A Word from Your Senior Nurse
"Hyperemesis is more than 'bad morning sickness.' It's a debilitating condition that can make a mother feel hopeless and isolated. Your role is not just to hang the IV bag but to be her advocate and support system. When you see that positive ketone dipstick and hear about significant weight loss, you're the one who connects those dots to sound the alarm for necessary medical care. In clinicals and on the NCLEX, remember: objective data (weight loss, lab values) always trumps subjective descriptions of severity when making clinical judgments. Trust the numbers, but also listen to your patient's story."
