Disorders
This specific life-threatening acute medical emergency—characterized by an absolute lack of insulin and the breakdown of fats into ketones—is a classic cause of severe metabolic acidosis with an elevated anion gap.
Diabetic Ketoacidosis (DKA)
The nurse elicits this classic clinical sign of hypocalcemia by tapping lightly over the facial nerve just in front of the ear, observing for unilateral twitching of the facial muscles.
Chvostek's sign
This specific cardiovascular assessment finding involves visible neck vein bulging when a patient is sitting at a 30 to 45-degree angle, serving as a primary indicator of hypervolemia
Jugular Venous Distension (JVD)
This specialized physical positioning strategy is used in severe ARDS to optimize oxygenation and recruit collapsed alveoli.
Prone Positioning
When managing a client with SIADH who presents with severe, symptomatic hyponatremia and confusion, the nurse should anticipate an order for this specific type of hypertonic intravenous fluid to be given very slowly.
3% Normal Saline (3% NaCl)
This endocrine disorder, characterized by a deficiency of Antidiuretic Hormone (ADH), causes the kidneys to excrete massive amounts of dilute urine, frequently leading to severe hypernatremia.
Diabetes Insipidus (DI)
Because potassium imbalances severely disrupt myocardial electrical conductivity, this continuous diagnostic procedure is the absolute priority for any client with hyperkalemia or hypokalemia.
continuous telemetry (or ECG monitoring)
This clinical phenomenon occurs when fluid moves out of the blood vessels into non-functional spaces like the pleural cavity, peritoneal cavity, or soft tissues, causing a low intravascular volume despite high total body water.
Third Spacing
When a oncology patient's Absolute Neutrophil Count (ANC) drops below this specific numerical value, the nurse must immediately institute protective, neutropenic isolation precautions.
1,000/mm³
Due to its mechanism of action inhibiting sodium-potassium-chloride cotransporters in the thick ascending limb of Henle, this loop diuretic is notorious for causing profound hypokalemia and ototoxicity if infused too rapidly.
Furosemide (Lasix)
This genetic disorder causes crescent-shaped cells that occlude small blood vessels. It requires immediate nursing interventions prioritizing hydration, oxygenation, and opioid pain management.
Sickle Cell Disease
To prevent bleeding after a bone marrow biopsy of the posterior iliac crest, the nurse should place the patient in this specific position for 30 to 60 minutes to apply natural pressure.
lying on the affected (or biopsied) side
Because both hyponatremia and hypernatremia cause severe cellular fluid shifts within the cranium, this is the absolute priority body system assessment for a nurse to monitor.
Neurological system
This classification of rescue medication (such as Albuterol) is given first during an acute asthma attack to rapidly dilate the airways.
short-acting beta agonist
This non-pharmacological nursing intervention is the primary, first-line treatment for a client with euvolemic hyponatremia caused by SIADH (Syndrome of Inappropriate Antidiuretic Hormone).
strict fluid restriction
Caused by an excess of glucocorticoids, this endocrine condition features classic physical manifestations including a "moon face," a "buffalo hump," truncal obesity with thin extremities, and purple skin striae.
Cushing syndrome
The sound heard auscultated over valve areas caused by turbulent blood flow through a diseased or incompetent valve
This paradoxical, life-threatening consumption coagulopathy is characterized by widespread micro-clots throughout the organs alongside massive external bleeding and a critically elevated D-Dimer level.
Disseminated Intravascular Coagulation (DIC)
To prevent catastrophic, irreversible neurological damage when administering hypertonic solutions, this is the maximum safe rate of sodium correction over a 24-hour period.
8 to 12 mEq/L per 24 hours
Administered to treat severe, symptomatic hyponatremia or increased intracranial pressure, this class of IV fluids can cause a side effect of rapid cellular dehydration and fluid overload if infused too fast.
hypertonic fluids (such as 3% Normal Saline)
This life-threatening complication of chest trauma occurs when air enters the pleural space and cannot escape, shifting mediastinal structures.
Tension Pneumothorax
This physical positioning maneuver is used immediately by nurses and parents to ease a hypercyanotic spell in a child with Tetralogy of Fallot.
Knee to chest position
This severe, life-threatening progression of hypothyroidism is characterized by extreme hypothermia, bradycardia, severe respiratory depression, non-pitting generalized edema, and cardiovascular collapse.
Myxedema Coma
This is the correct acid-base interpretation for the following clinical laboratory data: pH 7.15, PaCO₂ 38 mmHg, HCO₃ 14 mEq/L
Uncompensated Metabolic Acidosis
This medication is the standard intravenous antidote used to reverse the effects of a heparin overdose.
Protamine Sulfate
