Which assessment finding would be most concerning and require immediate intervention? ## 보기 1. Vomiting 3-4 times per day with ability to retain some fluids 2. Weight loss of 2 pounds over the past week 3. Mild ketones present in urine 4. Orthostatic hypotension with dizziness upon standing **✔ 정답** **정답: 4** ## 해설 Orthostatic hypotension with dizziness indicates severe fluid volume depletion requiring immediate IV fluids to prevent maternal-fetal complications. Other findings (vomiting 3-4x/day, mild weight loss, mild ketonuria) are less urgent and manageable with supportive care. ## 심화 해설 Correct Answer: 4. Orthostatic hypotension with dizziness upon standing Clinical Reasoning and Prioritization When assessing a client with severe nausea and vomiting in early pregnancy, the nurse must differentiate between expected symptoms of nausea and vomiting of pregnancy (NVP) and the more dangerous condition of hyperemesis gravidarum (HG). The key to answering this question lies in recognizing which finding signals a progression from a manageable condition to a state of physiological decompensation requiring immediate intervention. Analysis of Findings Using the Provided Evidence The provided case study defines HG as a condition distinct from typical morning sickness, marked by specific clinical indicators. Let's evaluate each option against this definition and the principles of hemodynamic stability. 1. Vomiting 3-4 times per day with ability to retain some fluids: While distressing, this finding is not the most concerning. The critical detail is the client's ability to retain some fluids. This suggests that oral hydration is still partially effective, and the client has not yet progressed to the point of severe, uncompensated volume depletion. This presentation warrants continued monitoring and antiemetic therapy but is not an immediate life-threatening emergency. 2. Weight loss of 2 pounds over the past week: This finding is clinically significant and points toward a diagnosis of HG. However, the provided evidence specifies that HG is marked by "weight loss exceeding 5% of pre-pregnancy weight" [1]. A 2-pound loss in one week, while concerning, does not automatically meet this severe threshold and represents a trend that requires intervention to prevent further deterioration. It is a problem to be managed, not an immediate crisis. 3. Mild ketones present in urine: The presence of ketonuria is a direct consequence of the metabolic starvation state described in HG [1]. When the body cannot utilize glucose due to inadequate intake, it breaks down fat for energy, producing ketones. Mild ketonuria confirms that the client is in a catabolic state and requires nutritional support. However, it is an expected laboratory finding for the clinical picture of HG and, while diagnostic, does not represent an immediate hemodynamic threat in its mild form. 4. Orthostatic hypotension with dizziness upon standing: This is the most concerning finding and requires immediate intervention. Orthostatic hypotension is a late and critical sign of significant dehydration and intravascular volume depletion, which are central features of severe HG [1]. The dizziness upon standing indicates that the body's compensatory mechanisms (vasoconstriction, increased heart rate) are failing to maintain cerebral perfusion against gravity. This signifies a state of hypovolemia severe enough to compromise cardiovascular stability. Left unaddressed, this can lead to further complications, including the electrolyte imbalances and potential arrhythmias highlighted in the case study [1]. The nurse's immediate priority is to ensure patient safety (preventing a fall due to dizziness) and to initiate interventions to restore hemodynamic stability, such as positioning the client supine and preparing for intravenous fluid resuscitation. This finding represents a direct threat to the client's physiological integrity, making it the highest priority for immediate action.References (research sources) - [1]Hidden Rhythms: A Complex Case of Hyperemesis Gravidarum-Induced Arrhythmias.Research articleAnderson TR, Carletto EJ, Barreto-Nadal V, Joubert E, Schutzer D. (2024) · DOI: 10.7759/cureus.75548 ## 임상 시나리오 Clinical Management of Hyperemesis Gravidarum with Orthostatic Hypotension When a client with severe nausea and vomiting of pregnancy (NVP) or hyperemesis gravidarum (HG) presents with orthostatic hypotension and dizziness, this signifies a state of significant intravascular volume depletion and hemodynamic instability. This is a clinical emergency requiring immediate intervention to prevent hypovolemic shock, acute kidney injury, and fetal compromise. Immediate Nursing Actions - **Prioritize Airway, Breathing, Circulation (ABCs):** Place the client in a supine position with a left lateral tilt to displace the uterus off the vena cava, maximizing venous return. Administer high-flow oxygen if the client shows signs of hypoxia or altered consciousness. - **Establish IV Access and Initiate Fluid Resuscitation:** Insert two large-bore (18-gauge or larger) IV catheters. Begin rapid infusion of isotonic crystalloid fluids (e.g., 0.9% Sodium Chloride or Lactated Ringer's solution) per facility protocol or provider order, typically starting with a 1-2 liter bolus. - **Continuous Hemodynamic Monitoring:** Monitor vital signs every 5-15 minutes, including orthostatic blood pressure measurements once the client is stable enough to stand. Assess level of consciousness, skin turgor, and mucous membranes for ongoing signs of dehydration. - **Strict Intake and Output (I&O):** Insert an indwelling urinary catheter if the client is unable to void or if hourly output monitoring is required to assess renal perfusion. A urine output of less than 30 mL/hour indicates ongoing renal hypoperfusion. Diagnostic and Pharmacological Considerations - **Laboratory Evaluation:** Obtain stat labs including a complete metabolic panel (CMP) to assess for electrolyte derangements (hypokalemia, hyponatremia), prerenal azotemia (elevated BUN/Creatinine ratio), and acid-base status. Check urine specific gravity and ketones. - **Correct Electrolyte Imbalances:** Replace potassium cautiously only after adequate urine output is confirmed. Severe hyponatremia requires slow correction to prevent osmotic demyelination syndrome. - **Antiemetic Therapy:** Administer IV antiemetics as prescribed, which may include ondansetron, metoclopramide, or promethazine. IV thiamine supplementation should be initiated before dextrose-containing fluids to prevent Wernicke encephalopathy in clients with prolonged vomiting. Ongoing Assessment and Safety - **Fall Risk Precautions:** Implement fall precautions due to dizziness and orthostatic instability. Keep the bed in the lowest position, assist with ambulation, and educate the client to rise slowly from a lying to sitting to standing position. - **Fetal Well-Being:** Once maternal hemodynamics are stabilized, assess fetal heart rate via Doppler. Continuous fetal monitoring may be indicated depending on gestational age and maternal condition. - **Psychosocial Support:** Acknowledge the severity of the condition and its impact on the client's pregnancy experience. Provide a calm environment and clear, repeated explanations of all interventions. ## 핵심 개념 - **Orthostatic Hypotension** — A drop in systolic BP of at least 20 mmHg or diastolic BP of at least 10 mmHg upon standing, indicating significant intravascular volume depletion. - **Hyperemesis Gravidarum** — A severe form of nausea and vomiting in pregnancy characterized by weight loss exceeding 5% of pre-pregnancy body weight, dehydration, and electrolyte imbalance. - **Hemodynamic Instability** — A state of inadequate blood flow and oxygen delivery to tissues, often manifested by hypotension, tachycardia, and altered mental status. - **Ketonuria** — The presence of ketone bodies in the urine, a byproduct of fat metabolism that occurs during starvation or prolonged vomiting due to insufficient carbohydrate intake. ## 같은 주제 문제 - [A nurse is assessing a client at 8 weeks gestation who was admitted with hyperemesis gravi…](https://mymerci.kr/pages/nclex_q.php?qn_id=542902) - [A nurse is assessing a pregnant client at 10 weeks gestation who presents with persistent …](https://mymerci.kr/pages/nclex_q.php?qn_id=542903) - [A nurse is caring for a 25-year-old client at 12 weeks gestation who has been admitted wit…](https://mymerci.kr/pages/nclex_q.php?qn_id=542905) - [A nurse is caring for a pregnant client diagnosed with hyperemesis gravidarum.
