What is the potassium level of Digitalis?
Hypokalemia potentiates the effect of digitalis and can result in digitalis toxicity. Serum potassium levels should range between 3.5 to 5.0 mEq/L. If the potassium value is 3.0 or less, the nurse should withhold the dose of digitalis, and notify the health care provider. 18.
What should a nurse do if Jonathan is dyspneic?
Since the nurse knows that Jonathan is already experiencing impaired gas exchange and is now obviously dyspneic, the first priority is to reduce the impaired gas exchange. The nurse should first elevate the head of the bed and assist Jonathan with deep breathing to promote improved oxygenation.
What is capoten used for?
ACE inhibitors have been shown to prolong survival in clients with heart failure. By lowering the blood pressure (reduced afterload), the workload on the heart is reduced.
Why should a nurse avoid using the Valsalva maneuver?
A client with cardiac problems should be instructed to avoid use of the Valsalva maneuver (bearing down) to prevent vagal stimulation which may result in bradycardia. The nurse should assess bowel sounds and bowel activity daily to ensure the Colace is effective. 9.
What should a nurse do to reduce energy expenditure?
In addition, the nurse should implement measures that will reduce the client's energy expenditure, such as assisting with transfers and ADLs. 12.
What is the best diuretic for fluid volume?
High-ceiling (loop) diuretics, such as furosemide (Lasix), is most effective for treating fluid volume overload. -Lasix reduces oxygen demand. Reducing the workload of the heart by reducing cardiac preload, will reduce, not promote the heart's consumption of oxygen. -It helps to lower blood pressure.
Does digoxin increase heart rate?
If a dose of digoxin has already been prescribed, it should be administered before taking further action. Digoxin slows the heart rate and increases the force of the heart's contraction, which is very useful in the treatment of Jonathan's type of cardiac dysrhythmia. 5.
How to fix electrolyte imbalance?
One solution to a mild electrolyte imbalance involves simply drinking more water. Treating an electrolyte imbalance involves either restoring levels if they are too low or reducing concentrations that are too high. If levels are too high, the treatment will depend on the cause of the excess.
What happens when the concentration of a certain electrolyte becomes higher than the body can regulate?
If levels of a substance are too high, the kidneys filter it from the body, and different hormones act to balance the levels. An imbalance presents a health issue when the concentration of a certain electrolyte becomes higher than the body can regulate. Low levels of electrolytes can also affect overall health.
What causes electrolytes to be low?
There are several reasons for an electrolyte imbalance, including: 1 kidney disease 2 not replenishing electrolytes or staying hydrated after exercise 3 prolonged periods of vomiting or diarrhea 4 poor diet 5 severe dehydration 6 an imbalance of the acid-base, or the proportion of acids and alkalis in the body 7 congestive heart failure 8 cancer treatment 9 some drugs, such as diuretics 10 bulimia 11 age, as the kidneys of older adults become less efficient over time
Why do I have an imbalance of electrolytes?
There are several reasons for an electrolyte imbalance, including: kidney disease. not replenishing electrolytes or staying hydrated after exercise. prolonged periods of vomiting or diarrhea. poor diet. severe dehydration. an imbalance of the acid-base, or the proportion of acids and alkalis in the body.
What are the symptoms of electrolyte imbalance?
A harmful concentration of magnesium, sodium, potassium, or calcium can produce one or more of the following symptoms: irregular heartbeat. weakness.
Why do I feel faint after a workout?
Electrolytes are a vital part of a person’s chemical makeup, and an imbalance can affect regular function. If you feel faint after a workout, this could be why. Regular monitoring and consuming electrolytes after intense exercise or sweating profusely can help to preserve levels. Be sure to stay hydrated at all times.
What are electrolytes in sports drinks?
However, there is far more to electrolytes than post-exercise refreshment. Electrolytes are chemicals that conduct electricity when mixed with water. They regulate nerve and muscle function, hydrate the body, balance blood acidity and pressure, and help rebuild damaged tissue.
How is electrolyte balance maintained?
Electrolyte balance is maintained by oral, or in emergencies, intravenous (IV) intake of electrolyte-containing substances, and is regulated by hormones, in general with the kidneys flushing out excess levels. In humans, electrolyte homeostasis is regulated by hormones such as antidiuretic hormones, aldosterone and parathyroid hormones.
When is electrolyte replacement needed?
In medicine, electrolyte replacement is needed when a person has prolonged vomiting or diarrhea, and as a response to strenuous athletic activity. Commercial electrolyte solutions are available, particularly for sick children (such as oral rehydration solution, Suero Oral, or Pedialyte) and athletes ( sports drinks ).
What happens when an electrolyte is placed in an electrolyte?
Main article: Electrolysis. When electrodes are placed in an electrolyte and a voltage is applied, the electrolyte will conduct electricity. Lone electrons normally cannot pass through the electrolyte; instead, a chemical reaction occurs at the cathode, providing electrons to the electrolyte.
What is electrolyte test?
Measurement of electrolytes is a commonly performed diagnostic procedure, performed via blood testing with ion-selective electrodes or urinalysis by medical technologists. The interpretation of these values is somewhat meaningless without analysis of the clinical history and is often impossible without parallel measurements of renal function. The electrolytes measured most often are sodium and potassium. Chloride levels are rarely measured except for arterial blood gas interpretations since they are inherently linked to sodium levels. One important test conducted on urine is the specific gravity test to determine the occurrence of an electrolyte imbalance .
What happens when a solute dissociates to form free ions?
If a high proportion of the solute dissociates to form free ions, the electrolyte is strong; if most of the solute does not dissociate, the electrolyte is weak. The properties of electrolytes may be exploited using electrolysis to extract constituent elements and compounds contained within the solution.
What conductors connect the plates in a fuel cell?
In some fuel cells, a solid electrolyte or proton conductor connects the plates electrically while keeping the hydrogen and oxygen fuel gases separated. In electroplating tanks, the electrolyte simultaneously deposits metal onto the object to be plated, and electrically connects that object in the circuit.
What is the main electrolyte in the body?
Sodium is the main electrolyte found in extracellular fluid and potassium is the main intracellular electrolyte; both are involved in fluid balance and blood pressure control. All known multicellular lifeforms require a subtle and complex electrolyte balance between the intracellular and extracellular environments.

When you are assessing their hydration status remember there are 3 categories of dehydration mild, moderate and severe . If you know your red flags you’ll be able to identify which kids are at risk for being severely dehydrated or even in shock. The goal of treatment is to replace fluids.
Why do kids get dehydrated?
Common causes for pediatric dehydration are fever, decrease fluid intake, vomiting and diarrhea from something like a stomach bug . Some less common but really important diagnoses to think of with dehydration are burn injuries and new onset diabetes or diabetic ketoacidosis.
Why is it important to write questions?
Writing questions helps to clarifymeanings, reveal relationships, establish continuity, and strengthenmemory. Also, the writing of questions sets up a perfect stage for exam-studying later. Recite: Cover the note-taking column with a sheet of paper.
Can dehydration occur in pediatric patients?
Hey guys in this lesson we are talking about dehydration in the pediatric patient. Dehydration can occur easily and quickly in pediatric patients. Because they have a higher percentage of total body water than adults as well as an increased body surface area they lose fluids more easily through their skin.
