- Have saline available for flush; do not start fluids until positive confirmation of placement (CXR).
- Position? trendelbeurg distend veins (acts as a tourniquet)
- If air gets in the line what position do you put the client in?
Left side trendelenburg (supine will make bubble travel to lung) Lying on left side traps bubble to left side bottom of heart
• When you are changing the tubing, how can you avoid getting air in the line?
Clamp it off
Valsalva
Take a deep breath and HUMMMMMM (increases thoracic pressure)
The client should be asked to perform the Valsalva maneuver during tubing changes. This helps avoid air embolism during tubing changes. The nurse asks the client to take a deep breath, hold it, and bear down.
If the intravenous line is on the right, the client turns his or her head to the left. This position increases intrathoracic pressure.

Q
- A shift to the left means that more immature than mature WBCs are at the site of inflammation or infection.
- Immature WBCs are less effective at phagocytosis and do not produce classic signs of inflammation, such as pus, redness, swelling, or heat. Fever is the only sign
- A “shift to the left” means that an increased number of immature neutrophils is present in the blood.
- A low total WBC count with a left shift indicates a recovery from bone marrow depression or an infection of such intensity that the demand for neutrophils in the tissue is higher than the capacity of the bone marrow to release them into the circulation.
- A high total WBC count with a left shift indicates an increased release of neutrophils by the bone marrow in response to an overwhelming infection or inflammation.
- A “shift to the right” means that cells have more than the usual number of nuclear segments; found in liver disease, Down syndrome, and megaloblastic and pernicious anemia.
- Monitor the WBC count closely in clients receiving chemotherapy because of the risk for neutropenia.

Q
- An advance directive is a legal document that’s used as a guideline for life-sustaining medical care of the client with an advanced disease or disability who can no longer indicate his own wishes.
- The advance directive is a document that allows the client to give directions about future medical care or to designate another person to make medical decisions if and when the client loses decision-making capacity.
- By initiating a code blue, the nurse didn’t follow the client’s advance directive and DNR order.
- The physician was correct to follow the client’s wishes and stop resuscitation efforts. The physician had the authority to stop the code.
- An advance directive should be part of the client’s medical record. The client should review the document with the physician at every admission because some conditions may be reversible and temporary, making portions of the advance directive inappropriate. Simply telling the client that the document will be included in his permanent record doesn’t address the need to review the directive with the physician. Advance directives are appropriate for clients of any age.
- Written document recognized by state law that provides directions concerning the provision of care when a client is unable to make his or her own treatment choices; the two basic types of advance directives include living wills and durable powers of attorney.
- This document can include
- living will
- Living will: lists the medical treatment that a client chooses to omit or refuse if the client becomes unable to make decisions and is terminally ill.
- instructs the physician not to administer life-sustaining treatment
- Living wills are required to be in writing and signed by the client. The client’s signature must be witnessed by specified individuals or notarized. Many states prohibit any employee, including a nurse of a facility where the client is receiving care, from being a witness.
- The living will is a witnessed document indicating the client’s desire to be allowed to die a natural death, rather than be kept alive by heroic life-sustaining measures.
- a written document that identifies a person’s preferences regarding medical interventions to use in a terminal condition, irreversible coma, or persistent vegetative state with no hope of recovery.
- Employees of the health care facility should not sign as witnesses; therefore, the nurse cannot sign as witness.
- The living will applies to decisions that will be made after a terminally ill client is incompetent and has no reasonable possibility of recovery.
- gives information about what the client wants if he is in a terminal or permanently unconscious state.
- “initiate potentially life-prolonging treatment unless the client refuses.”- A living will doesn’t go into effect unless the client is unable to make his own decisions. The nurse should give all appropriate care while also maintaining the client’s right to refuse treatment.
- health care power of attorney
- names another person to act on the client’s behalf for medical decisions in the event that the client can’t act for himself.
- Durable powers of attorney: appoints a person (health care proxy) chosen by the client to make health care decisions on the client’s behalf when the client can no longer make decisions.
- A health care power of attorney, not an advance directive, gives others power to make decisions about a client’s medical care.
- living will
- The living will and health care power of attorney aren’t the same.
- A living trust, which concerns property ownership, wouldn’t address the client’s concerns.

- Peristalsis returns gradually, usually the second or third day after surgery. Bowel sounds will be absent until then. complications.
- When the client resumes a solid diet postoperatively, failure to pass stool within 48 hours may indicate constipation.
- Urinary control may not return for 6 to 8 hours after surgery owing to the effects of anesthesia and bladder manipulation during surgery. Urine retention is common; voiding a small amount of urine after surgery may be indicative of urine retention.
- If the client does not have a Foley catheter, the client is expected to void within 6 to 8 hours postoperatively depending on the type of anesthesia administered; ensure that the amount is at least 200 mL.
- report immediately: A temperature higher than 37.7° C (100° F) or lower than 36.1° C (97° F) and a falling systolic blood pressure, lower than 90 mm Hg, are usually considered reportable immediately.

Q
- The tube is flushed with 30 to 50 mL of water or NS (depending on agency policy) to ensure that all medication has been instilled. The tube is then clamped for 30 to 60 minutes (depending on the medication and agency policy) to ensure it is absorbed (if the tube is not clamped and is reattached to suction then the medication will be aspirated out with the suction).
- Flush the tube with 30 to 50 mL of water or NS (depending on agency policy) before and after medication administration and before and after bolus feeding.
- Change the feeding container and tubing every 24 hours.
- Do not hang more solution than required for a 4-hour period; this prevents bacterial growth.
Position the client in a high Fowler’s position; if comatose, place in high Fowler’s and on the right side.
- usually, if the residual is less than 100 mL, feeding is administered; large-volume aspirates indicate delayed gastric emptying and place the client at risk for aspiration.
- Provides liquefied foods into the gastrointestinal tract via a tube
- Warm the feeding to room temperature to prevent diarrhea and cramps.
- Administer the feeding at the prescribed rate or via gravity flow (intermittent bolus feedings) with a 50- to 60-mL syringe with the plunger removed.
- Gently flush with 30 to 50 mL of water or normal saline (depending on agency policy) with the irrigation syringe after the feeding.
- Flush the tube with 30 to 50 mL of water or NS (depending on agency policy) before and after medication administration and before and after bolus feeding.
- Do not allow the feeding bag to empty.

Q
- The nurse should not administer more than 3 mL per intramuscular or 1 mL per subcutaneous injection site; larger volumes are difficult for an injection site to absorb
- are administered at an angle of 45 to 90 degrees, depending on the size of the client.
- Subcutaneous needles are typically 3/8 to 5/8 inches (0.95 to 1.6 cm) in length.
- The skin should be pinched up at the injection site to elevate the subcutaneous tissue.
A
subcutaneous injections
14
Q
- The nurse should not administer more than 3 mL per intramuscular or 1 mL per subcutaneous injection site; larger volumes are difficult for an injection site to absorb and, if prescribed, need to be verified.
- always means an injection route and parenteral medications are administered by intravenous, intramuscular, subcutaneous, or intradermal injection
- pain with infusion is a sign of Catheter position at the insertion site due to movement. The catheter pressing against the vein causes the pain. This would be a common result due to normal movement of the client throughout the day.
- To give a Z-track injection, a nurse measures the correct medication dose and then changes the needle on the syringe. Changing the needle decreases pain by eliminating any medication that may have been left on the needle and that could irritate the skin.

Q
- Deep breathing helps prevent microatelectasis and pneumonitis
- deep breathing helps force air and fluid out of the pleural space into the chest tubes.
- The diaphragm is the major muscle of respiration; deep breathing causes it to descend, not elevate, thereby increasing the ventilating surface.
- the primary reason for deep breathing is to expand alveoli and prevent atelectasis.
- Instruct the client that a sitting position gives the best lung expansion for coughing and deep-breathing exercises.
- Instruct the client to breathe deeply three times, inhaling through the nostrils and exhaling slowly through pursed lips.
- Instruct the client that the third breath should be held for 3 seconds; then the client should cough deeply three times.
- The client should perform this exercise every 1 to 2 hours.

Q
- A nurse is taking a client’s blood pressure and fails to recognize an auscultatory gap. What should the nurse do to avoid recording an erroneously low systolic blood pressure?
- Inflate the cuff at least another 30 mm Hg after she can’t palpate the radial pulse.
- Explanation:
- The nurse should wrap an appropriate-size cuff around the client’s upper arm and then place the diaphragm of the stethoscope over the brachial artery. The nurse should then rapidly inflate the cuff until she can’t palpate or auscultate the pulse, then continue inflating until the pressure rises another 30 mm Hg.

20
Q
- Discharge teaching should be performed before the date of the scheduled procedure.
- Instruct the client not to drive, make important decisions, or sign any legal documents for 24 hours after receiving general anesthesia.
- sutures usually are removed in the physician’s office 7 to 10 days after surgery.
- staples are removed 7 to 14 days after surgery and that the skin may become slightly reddened when they are ready to be removed.
- avoid lifting for 6 weeks if a major surgical procedure was performed.
- Instruct the client with an abdominal incision not to lift anything weighing 10 pounds or more and not to engage in any activities that involve pushing or pulling.
- The client usually can return to work in 6 to 8 weeks depending on the procedure and as prescribed by the physician.

A
Ice application
23
Q
- Elevating the arm promotes venous drainage and reduces edema; applying warmth increases circulation and eases pain and edema. Ice application would relieve pain but not edema.
- Edema, pain, and coolness at the site
- Pallor, coolness, and swelling are the results of IV fluid being deposited in the subcutaneous tissue.
- may or may not have a blood return
- is a form of tissue damage; it may also called extravasation.
- is seepage of the IV fluid out of the vein and into the surrounding interstitial spaces.
- occurs when an access device has become dislodged or perforates the wall of the vein or when venous backpressure occurs because of a clot or venospasm.
- Evaluate the IV site for infiltration by
- occluding the vein proximal to the IV site.
- If the IV fluid continues to flow, the cannula is probably outside the vein (infiltrated)
- if the IV flow stops after occlusion of the vein, the IV device is still in the vein.
- Lower the IV fluid container below the IV site, and monitor for the appearance of blood in the IV tubing; if blood appears, the IV device is most likely in the vein.
- occluding the vein proximal to the IV site.
- If infiltration has occurred, remove the IV device immediately; elevate the extremity and apply compresses (warm or cool, depending on the IV solution that was infusing and the physician’s prescription) over the affected area.
- Do not rub an infiltrated area, which can cause hematoma.
- An infiltrated IV is one that has dislodged from the vein and is lying in subcutaneous tissue.
- When the pressure in the tissues exceeds the pressure in the tubing, the flow of the IV solution will stop.

33
* Steel needles or butterfly sets
* The set is a wing-tip needle with a metal cannula, plastic or rubber wings, and a plastic catheter or hub.
* The needle is 0.5 to 1.5 inches in length, with needle gauge sizes from 16 to 26.
* Infiltration is more common with these devices.
* The butterfly infusion set commonly is used in children and older clients, whose veins are likely to be small or fragile.
* Plastic cannulas
* Plastic cannulas may be an over-the-needle device or an in-needle catheter and are used primarily for short-term therapy.
* The over-the-needle device is preferred for rapid infusion and is more comfortable for the client.
* The in-needle catheter can cause catheter embolism if the tip of the cannula breaks.
IV cannulas
34
* large-diameter lumen needles or cannulas are used, such as a 14-, 16-, 18-, or 19-gauge
* For rapid emergency fluid administration
* blood products

* Change the IV **tubing** every **24 to 72 hours**
* Do not let an IV bag or bottle of solution hang for **more than 24 hours** to diminish the potential for bacterial contamination and possibly sepsis.
* Actions for Inserting a Peripheral Intravenous Line
* prime the IV tubing to remove air from the system
* The vein is stabilized to prevent its movement and the skin is punctured.
* Actions for Removing a Peripheral Intravenous Line
* The nurse is careful to stabilize the catheter so that it is not pulled, resulting in vein trauma.

* Case
* Treat the 12-year-old with asthma first by initiating an albuterol treatment. This action is quick to initiate, and the child or parent can be instructed to hold the apparatus while you attend to other clients. The firefighter is in greater respiratory distress than the 12-year-old; however, managing a strong combative client is difficult and time consuming (i.e., the 12-year-old could die if you spend too much time trying to control the firefighter). Attend to the teenager with a crush injury next. Anxiety and tachycardia may be caused by pain or stress; however, the swelling suggests hemorrhage. Next attend to the woman with burns on the forearms by providing dressings and pain management. The child with burns over more than 70% of the anterior body should be given comfort measures; however, the prognosis is very poor. The prognosis for the client in cardiac arrest is also very poor, and the CPR efforts have been prolonged.
