Infant

Which nursing interventions would be appropriate for a client diagnosed with deficient fluid volume? Select all that apply.

Intravenous therapy Nutrition management Electrolyte management If a client is at a fluid volume deficit, intravenous therapy may be ordered by the primary care provider to replenish fluids and electrolytes, warranting fluid and electrolyte management. Nutrition management may help to increase and maintain electrolyte levels by adding foods high in certain electrolytes to the diet. Hypervolemia refers to fluid volume excess. Fluid restriction would be contraindicated because the client is already at a deficit. Edema would be monitored in the case of fluid volume excess.

A client is admitted to the unit with a diagnosis of intractable vomiting for 3 days. What acid-base imbalance related to the loss of stomach acid does the nurse observe on the arterial blood gas (ABG)?

Metabolic alkalosis

A client is admitted to the unit with a diagnosis of intractable vomiting for 3 days. What acid-base imbalance related to the loss of stomach acid does the nurse observe on the arterial blood gas (ABG)?

Metabolic alkalosis Metabolic alkalosis is associated with an excess of HCO3, a decrease in H+ ions, or both, in the extracellular fluid (ECF). This may be the result of excessive acid losses or increased base ingestion or retention. Loss of stomach acid may result in this condition. Metabolic acidosis is a proportionate deficit of bicarbonate in ECF. The deficit can occur as the result of an increase in acid components or an excessive loss of bicarbonate such as in diarrhea. Respiratory acidosis is when the carbon dioxide level is high and the ph is low. Respiratory alkalosis is when the carbon dioxide level is low and the ph is high.

A nurse monitoring a client's IV infusion auscultates the client's lung sounds and detects crackles in the bases in lungs that were previously clear. What would be the most appropriate intervention in this situation?

Phlebitis

A 50-year-old client with hypertension is being treated with a diuretic. The client reports muscle weakness and falls easily. The nurse should assess which electrolyte?

Potassium

The nurse is determining a site for an IV infusion. What guideline should the nurse consider?

Scalp veins should be selected for infants because of their accessibility. Potential sites for neonates and children include: veins of the scalp (neonates under 6 months) because of the accessibility, and dorsal veins of the foot (toddlers). The antecubital veins are not a good choice for infusion because flexion of the client's arm can displace the IV catheter. The veins in the leg of an adult should not be used, unless other sites are inaccessible, because of the danger of stagnation of peripheral circulation and possible serious complications, such as deep vein thrombosis. Veins in surgical areas are not recommended and would not increase the potency of medication.

A nurse uses an infusion pump to administer the IV solution to a client. The nurse is aware that an infusion pump adjusts the pressure according to the resistance it meets and there is a possibility that the needle may get displaced. How would a change in the needle's position affect the infusion pump?

The pump will continue to infuse fluid even when the needle is displaced.

The nurse is preparing to access an implanted port when administering intravenous fluids and medications. What best practice should be used when accessing this port?

The system is accessed with a noncoring needle and patency is maintained by periodic flushing.

The nurse has inserted a peripheral intravenous catheter. When applying a transparent dressing, what is the nurse's best action?

The transparent dressing should be placed in such a manner as to allow full coverage and visibility of the insertion site, without excessively covering the tubing.

A client's most recent blood work indicates a K+ level of 7.2 mEq/L (7.2 mmol/L), a finding that constitutes hyperkalemia. For what signs and symptoms should the nurse vigilantly monitor?

cardiac irregularities
