Q

• Avoid astragalus and ginseng, since they can increase BP before and during surgery.
• Avoid garlic, vitamin E, ginkgo, and fish oils because they can increase bleeding.
• Avoid kava and valerian because they can cause excessive sedation.
• In general, stop taking all herbs 2 to 3 weeks before any surgical procedure. Consult your HCP for specific instructions.
• Take multivitamins until the day before surgery. Taking them on the day of surgery on an empty stomach may contribute to nausea and vomiting after surgery.

A

factors may contribute to the development of emergence delirium, a condition that may be falsely labeled as senility or dementia.

33
Q

including fluid and electrolyte imbalances, coagulopathies, increased risk for infection, and impaired wound healing. Because the kidneys metabolize and excrete many drugs, a decrease in renal function can lead to an altered response to drugs and unpredictable drug elimination. Renal function tests (e.g., serum creatinine, blood urea nitrogen [BUN]) are often done before surgery.

A

Renal dysfunction is associated with several problems

34
Q

during the first trimester.

A

Maternal and fetal exposure to anesthetics should be avoided

Q

because of changes in metabolic rate. If the patient takes a thyroid replacement drug, check with the ACP about administering the drug on the day of surgery. If the patient has a history of thyroid dysfunction, laboratory tests may be done to determine current levels of thyroid function.

A

Hyperthyroidism or hypothyroidism can place the patient at surgical risk

42
Q

can occur if a patient abruptly stops taking replacement corticosteroids. The patient may need additional IV corticosteroid therapy from the stress of surgery

A

Addisonian crisis or shock

43
Q

Impairment of the immune system can lead to delayed wound healing and increased risk for infections

A

Corticosteroids used in immunosuppressive doses may be tapered before surgery.

may have surgery if needed.

Patients with active chronic infections such as hepatitis B or C, acquired immunodeficiency syndrome, or tuberculosis

Q

to allow time to obtain special equipment needed for the patient’s care (e.g., longer instruments for abdominal surgery).

A

patient is severely obese (body mass index [BMI] greater than 40 kg/m2)

48
Q

It predisposes the patient to wound dehiscence, wound infection, and incisional herniation after surgery. Adipose tissue is less vascular than other types of tissue. The patient may be slower to recover from anesthesia because adipose tissue absorbs and stores inhalation agents, so they leave the body more slowly.

A

Obesity stresses the heart and lung systems and makes access to the surgical site and anesthesia administration more difficult

49
Q

are particularly important because these substances are essential for wound healing

Q

history and physical examination (H&P) in their chart.12 This may be done in advance of surgery or on the day of surgery.

A

Joint Commission requires that all patients admitted to the OR have a documented

51
Q

Findings from the H&P enable the ACP to assign the patient a physical status

A

rating for anesthesia administration

52
Q

It uses a scale of P1 to P6. A rating of P6 is reserved for a brain-dead patient undergoing organ procurement. Patients undergoing surgery in ambulatory or outpatient settings generally have ratings of P1, P2, or P3. Other designations can be added to the ASA status (e.g., “E” to designate an “emergent” procedure).

A

Rating range for anesthesia administration

53
Q

sensory, process, and procedural.

A

preoperative teaching includes 3 types of information:

54
Q

patients find out what they will see, hear, smell, and feel during the surgery
-For example, you may tell them that the OR will be cold, but they can ask for a warm blanket; the lights in the OR are bright; or many unfamiliar sounds and specific smells will be present.

A

sensory information,(preoperative teaching)

55
Q

may not want specific details but just the general flow of what is going to happen.
-This information would include the patient’s transfer to the holding area, visits by the nurse and the ACP before transfer to the OR, and waking up in the PACU.

A

process information (preoperative teaching)

56
Q

, patients desire details that are more specific.

A

procedural information

Q

is an active, shared decision-making process between the HCP and recipient of care.

A

Informed consent

59
Q

. First, there must be adequate disclosure of the (1) diagnosis; (2) nature and purpose of the proposed treatment; (3) risks and consequences of the proposed treatment; (4) probability of a successful outcome; (5) availability, benefits, and risks of alternative treatments; and (6) prognosis if treatment is not instituted.

A

Three conditions must be met for consent to be valid

60
Q

, the patient must show a clear understanding of the information before receiving sedating preoperative drugs. If a patient is sedated prior to signing the consent, surgery may be cancelled or delayed

A

Second conditions must be met for consent to be valid

61
Q

, the recipient of care must give consent voluntarily. The patient must not be persuaded or coerced in any way by anyone to undergo the procedure.

A

Third conditions must be met for consent to be valid

62
Q

a legally appointed representative or responsible family member may give written permission.

A

If the patient is a minor, unconscious, or mentally incompetent to sign the permit,

63
Q

is one who is younger than the legal age of consent but is recognized as having the legal capacity to provide consent.

A

emancipated minor

64
Q

is to witness the signing of the document. This means that as a nurse, you attest to the fact that the patient’s signature was valid.

A

(consent) most states, the registered nurse’s legal role

65
Q

next of kin may give consent when immediate medical treatment is necessary to preserve life or prevent serious impairment to life or limb and the patient is incapable of giving consent. If reaching the next of kin is not possible, the HCP may begin treatment

A

Emergency surgery rules about consent

66
Q

note in the chart must document the medical necessity of the procedure. In the case of an emergency in which consent cannot be obtained, you will usually need to complete an event report because it is an occurrence that is inconsistent with routine agency practices.

A

emergency surgery without consent requirements

67
Q

immediately before surgery include final preoperative teaching, assessment, and communication of pertinent findings. In addition, ensure that all preoperative orders are done and that the chart is complete and goes with the patient to the OR. It is especially important to verify the presence of a signed informed consent form, results of laboratory and diagnostic studies, an H&P, a record of any consultations, baseline vital signs, proper skin preparation, and completed nursing notes. The surgical site is identified and marked with an indelible marker by the surgeon and documented to show that the patient agrees

A

Nurses role on day of surgery

68
Q

empty bladder prevents involuntary elimination under anesthesia and reduces the risk for urinary retention during the early postoperative recovery.

A

encourage pts to void before surgery

69
Q

Benzodiazepines are used for their sedative and amnesic properties. Anticholinergics are sometimes given to reduce secretions. Opioids may be given to decrease pain and anesthetic requirements during surgery. Antiemetics can decrease nausea and vomiting.

A

medications given during preoperative

70
Q

Other drugs that may be given before surgery include antibiotics, eyedrops, and routine prescription drugs. Antibiotics may be given throughout the perioperative period for patients with a history of prosthetic heart valve to prevent infective endocarditis and for patients with previous joint replacement. They also may be given when wound contamination is a potential risk (e.g., GI surgery).

A

other drugs given preoperative surgery
