Study Notes

Intravenous Therapy

Intravenous (IV) therapy delivers medications and fluids directly into the bloodstream.
Dosage calculations are essential for administering IV medications, including flow rate, time to completion, and drug reconstitution.
Reconstituting medications involves mixing a powder with a diluent to create a solution suitable for administration.
Clinical situations requiring IV fluids include dehydration, electrolyte imbalances, and shock.
Sterile technique is crucial when preparing IV medications to prevent infections.
IV medications can be administered via IV push (directly into a vein) or infusion (slowly over time).
Peripheral infusions use veins in the arms or hands, while central infusions access larger veins in the chest or neck, allowing for higher volumes and more concentrated medications.
Saline locks are used to maintain IV access for intermittent infusions while preventing blood clotting.

Central Lines

Central venous catheters (CVCs), Peripherally Inserted Central Catheters (PICCs), and midline catheters are all types of central access devices.
CVCs are inserted into larger veins near the heart, while PICCs are inserted in a peripheral vein and advanced to the superior vena cava.
Midline catheters are inserted in an upper extremity vein and can be used for short-term therapies.
Sterile technique is essential when managing central lines, including dressing changes and medication administration.

Shock

Shock is a life-threatening condition that occurs when the body's tissues do not receive adequate oxygen and nutrients.
Types of shock include hypovolemic, cardiogenic, anaphylactic, neurogenic, and septic shock.
Assessments are crucial for identifying early warning signs of shock.
Blood transfusion might be required for hypovolemic shock.
Monitoring vital signs, urine output, and laboratory values is essential for assessing shock progression.

Airway Management and Ventilation

Airway management techniques like oral airways, bag-valve-mask ventilation, tracheostomy, and intubation are used to maintain an open airway and deliver oxygen.
Pneumothorax, hemothorax, and pleural effusion are conditions that affect the pleural space, potentially impairing lung function.
Chest tubes help drain air or fluid from the pleural space.

Preoperative Period

Preoperative assessment identifies risk factors and potential complications related to surgery.
Drug classifications and their effects on the surgical client should be carefully considered.
Preadmission clinics facilitate pre-operative assessments, provide education, and address any concerns.
Informed consent ensures the patient understands the risks and benefits of surgery.
Preoperative teaching includes information about pain management, post-operative procedures, and recovery expectations.

Postoperative Period

Postoperative care focuses on monitoring the patient's vital signs, pain management, and recovery.
Common postoperative complications include atelectasis, pneumonia, deep vein thrombosis, pulmonary embolism, hemorrhage, and wound infection.
Discharge planning includes providing education, referrals, and support for the patient at home.

Malnutrition

Malnutrition occurs when the body doesn't receive the required amount of nutrients.
Factors contributing to malnutrition include poverty, lack of access to food, and poor dietary choices.
Hospitalization can increase the risk of malnutrition due to altered appetite and changes in dietary intake.
Obesity is a serious health concern associated with chronic diseases such as diabetes, heart disease, and certain types of cancer.
