A G1P0 at 36 weeks presents with BP 172/114, headache, and 3+ proteinuria. Per 2026 standards, what is the initial management priority for blood pressure control and the target range?
Show answer →Immediate goal: Reduce BP to 140-150/90-100 mmHg within 30-60 minutes to prevent maternal stroke. First-line agents: IV Labetalol (20mg, then 40-80mg every 10 min) or IV Hydralazine (5-10mg every 20 min). Oral Nifedipine (10-20mg) is a preferred oral alternative. Clinical Pearl: Do not drop BP too low or too fast, as this can cause placental hypoperfusion and non-reassuring FHR. Exam Tip: NCC emphasizes that severe BP is 160/110+ on two occasions 15 mins apart, but treatment should NOT be delayed if initial BP is extremely high. Avoid Labetalol in patients with asthma or active CHF.
A patient presents at 34 weeks with an acute asthma attack. The FHR shows a baseline of 150 bpm with minimal variability and recurrent late decelerations. What is the priority action?
Show answer →The priority is aggressive medical stabilization of the mother (high-flow oxygen, nebulized SABA, IV steroids). Fetal distress during an asthma exacerbation is typically a direct result of maternal hypoxia and decreased uterine blood flow. In most cases, the FHR will return to a reassuring pattern once maternal oxygenation and ventilation are restored. Emergency delivery should be deferred until the mother is stabilized, as surgery during an acute attack carries high maternal risk.
A patient with HG presents with muscle weakness, diminished deep tendon reflexes, and EKG changes (U-waves). Which electrolyte abnormality is most likely, and what is the nursing priority?
Show answer →Hypokalemia (low potassium). Priority: Cardiac monitoring and IV potassium replacement (never IV push). Hypokalemia results from direct loss in vomitus and renal compensation for metabolic alkalosis. NCC Tip: Always check magnesium levels as well, as refractory hypokalemia is often caused by concurrent hypomagnesemia; potassium cannot be effectively replaced if magnesium is low.
For a patient restricted to bed due to an epidural or exhaustion, the nurse implements the use of a peanut ball. What is the primary physiological goal of this tool regarding the pelvic outlet?
Show answer →The primary goal is to promote pelvic opening and fetal rotation, particularly for Occiput Posterior (OP) or asynclitic presentations. By keeping the legs abducted and internally/externally rotated while side-lying, the peanut ball increases the transverse diameter of the pelvic outlet. Clinical Evidence: Use of the peanut ball is associated with a significantly shortened first and second stage of labor and a reduction in the rate of Cesarean sections for failure to progress. It is a vital tool for the active management of a patient with limited mobility.
During a Massive Transfusion Protocol (MTP), the patient has received 6 units of PRBCs. The nurse notes new-onset EKG changes (prolonged QT interval) and muscle tremors. What is the most likely cause, and what is the immediate intervention?
Show answer →Hypocalcemia caused by citrate toxicity. Citrate is an anticoagulant in stored blood that binds to the patient's ionized calcium. Intervention: Administer Calcium Gluconate (typically 1g IV for every 2-4 units of blood). Clinical Pearl: Citrate is metabolized by the liver; patients with liver dysfunction or those receiving rapid transfusions are at higher risk. NCC Exam Focus: Recognize the link between MTP, hypocalcemia, and the need for calcium replacement to maintain cardiac contractility and coagulation.
