Which electrolyte imbalance is most likely to result in potentially lethal arrhythmias?
Hyperkalemia
A patient has lost a large amount of blood and fluid due to surgery and states he is thirsty.
The nurse should recognize which process is a cause for his thirst?
Fluids moving from inside the cells into the ECF
Which fluid makes up the largest proportion of body weight?
Intracellular fluid
Which condition places a pediatric patient at highest risk for developing hypokalemia?
Vomiting and diarrhea
A pediatric patient with isotonic fluid deficit is being treated aggressively with both fluid volume and electrolytes.
For which reason should the nurse recognize that this type of fluid volume deficit is potentially more dangerous in children?
Fluid is a higher percentage of total body weight in children.
Which is one of the most common cause of hyponatremia?
Loss of body fluids
Which is the most prevalent intracellular ion?
Potassium
Which is the primary trigger of the renin-angiotensin-aldosterone system (RAAS)?
Low blood pressure
A patient who is at risk for developing osteoporosis asks which foods she should consume to increase calcium.
Which recommendation should the nurse make?
"Increase dairy products and green, leafy vegetables."
The nurse is caring for a patient with dehydration.
The nurse should expect the patient to have which clinical manifestations?
Thirst, headache, dizziness, confusion
A patient has been diagnosed with mild hyponatremia and asks the nurse how this can be prevented from reoccurring. Which is the nurse's correct response?"Add salt to food when cooking."The nurse should recognize that which process regulates the excretion of water from the kidneys?Release of antidiuretic hormone (ADH)When examining laboratory results, the nurse notices that a patient's serum albumin level is low. The nurse recognizes the significance of decreased albumin because it can result in a decrease in which mechanism of fluid balance?Colloid osmotic pressureA patient with a chloride level of 70 mEq/L is presenting with confusion, sweating, and shallow respirations. Which cause should the nurse suspect for the patient's clinical manifestations?A loss of gastrointestinal secretionsThe nurse is discussing the osmolarity of an intravenous fluid with a colleague. Which description of osmolarity by the nurse is accurate?Concentration of solutes in body fluidsThe nurse has assessed the swelling in the lower extremities of a patient over the past few days as edema. Which statement describes the etiology of edema?Accumulation of interstitial fluidA teenager has eaten a bag of very salty potato chips and reports being very thirsty. Which physiological response will occur?Increased secretion of antidiuretic hormone (ADH)
