A client with cancer develops signs of confusion, headache, and visual disturbances.
The nurse suspects superior vena cava syndrome. Which symptoms support the nurse's suspicion? Select all that apply.
Severe abdominal pain.
Shortness of breath.
Decreased urine output.
Jugular vein distension.
Edema of the face and arms.
Chest pain and shortness of breath.
Correct Answer : B,D,E,F
The clinical scenarios involve oncological emergencies, acute neurological deficits, hepatic coagulopathy, and end of life ethics. Knowledge of vascular obstruction, cerebral perfusion, liver physiology, and therapeutic communication is required to identify life threatening complications and uphold patient autonomy in advanced illness.
Choice A rationale
Abdominal pain is not a primary manifestation of superior vena cava syndrome. This condition involves obstruction of blood flow through the superior vena cava, primarily affecting the upper body, head, and neck rather than the abdominal cavity or viscera.
Choice B rationale
Dyspnea occurs as the tumor or thrombus compresses the superior vena cava, leading to impaired venous return and pulmonary congestion. This increased venous pressure in the upper thoracic region compromises respiratory efficiency and necessitates urgent medical intervention for stabilization.
Choice C rationale
Decreased urine output is typically associated with renal failure or systemic hypovolemia rather than localized superior vena cava obstruction. While cardiac output might eventually drop, oliguria is not a classic diagnostic symptom used to confirm this specific oncological emergency.
Choice D rationale
Obstruction of the superior vena cava causes a significant increase in venous pressure above the heart. This backup of blood leads to visible engorgement of the jugular veins as the blood cannot return efficiently to the right atrium.
Choice E rationale
Edema in the upper extremities and face results from increased capillary hydrostatic pressure due to venous return blockage. Fluid shifts into the interstitial spaces of the head, neck, and arms, causing the characteristic swelling and puffiness seen.
Choice F rationale
Chest pain and shortness of breath arise from increased intrathoracic pressure and decreased cardiac preload. The physical mass causing the syndrome often occupies the mediastinal space, leading to localized discomfort and significant respiratory distress during the acute phase.

Correct Answer is A
Explanation
This scenario requires the application of electrocardiography interpretation skills to identify specific cardiac arrhythmias based on rhythm regularity, presence of P waves, and heart rate. Recognizing atrial fibrillation is essential for determining appropriate anticoagulation and rate control interventions for telemetry clients.
Choice A rationale
Atrial fibrillation is characterized by an irregularly irregular rhythm and a lack of discernible P waves. The rapid, disorganized electrical activity in the atria leads to ineffective pumping and increased risk for thromboembolic events or symptomatic palpitations.
Choice B rationale
Sinus tachycardia follows a regular rhythm with identifiable P waves preceding every QRS complex. The rate is typically between 101 and 150 beats per minute. This does not match the irregularly irregular rhythm or absent P waves described.
Choice C rationale
First degree heart block involves a delayed conduction through the atrioventricular node, resulting in a prolonged PR interval greater than 0.20 seconds. However, the rhythm remains regular with a 1 to 1 ratio of P waves to QRS.
Choice D rationale
Ventricular tachycardia presents as three or more consecutive premature ventricular contractions with a rate usually exceeding 100 per minute. It shows wide, bizarre QRS complexes and is typically a regular rhythm, which is inconsistent with this client strip.
Correct Answer is D
Explanation
Managing acute decompensated heart failure requires understanding perfusion pressure and cardiovascular hemodynamics. Knowledge of mean arterial pressure and vasopressor pharmacology is necessary. The priority is maintaining vital organ perfusion when the MAP falls below critical thresholds required for cellular oxygenation.
Choice A rationale
Fluid boluses can exacerbate pulmonary edema in acute decompensated heart failure. While MAP is low, adding volume increases preload, which a failing left ventricle cannot pump, leading to further respiratory distress and worsening of the cardiac crisis.
Choice B rationale
Intubation addresses respiratory failure and oxygenation but does not directly correct the primary hemodynamic issue of low perfusion pressure. While it may become necessary, the immediate priority is restoring MAP to ensure coronary and renal perfusion.
Choice C rationale
High Fowler's position assists with oxygenation by reducing venous return and decreasing pulmonary congestion. However, in the presence of a dangerously low MAP of 55 mm Hg, this position may further decrease cerebral and systemic perfusion.
Choice D rationale
A MAP below 60 to 65 mm Hg indicates inadequate organ perfusion. Norepinephrine provides potent vasoconstriction and minimal inotropy, raising systemic vascular resistance to increase the MAP quickly, thereby protecting the brain, heart, and kidneys from ischemia..
