,NU 170 Exam 1 142 Questions
Question 1 NU 170 Exam 1
Preoperative Phase
CORRECT ANSWER
Decision for surgery is made and ends when the patient is transferred to the operating room
Rationale: The preoperative phase refers to the period between the decision for surgery and the actual surgical procedure, when the patient is
prepared and assessed for anesthesia and surgery. Therefore, the decision for surgery being made and ending when the patient is transferred to
the operating room marks the beginning of this phase, as it sets the stage for the patient's surgical preparation and care.
Question 2 NU 170 Exam 1
Intraoperative Phase
CORRECT ANSWER
Begins with the patient's entry into the operating room and ends with admittance to the postanesthesia care unite (PACU) or recovery
room
Rationale: The intraoperative phase is a specific period in the perioperative process because it focuses on the direct surgical intervention and the
sequence of events that occurs within the operating room, which necessitates a clear and defined timeframe for that process. By beginning with
the patient's entry into the operating room and ending with admittance to the PACU, this timeframe captures the entirety of the surgical
procedure, from preparation to recovery, which is essential for monitoring and managing the patient's care during this critical phase.
Question 3 NU 170 Exam 1
Postoperative Phase
CORRECT ANSWER
Begins with the patient's admittance to the PACU and ends with the patient's complete recovery from the surgical intervention
Rationale: The postoperative phase is defined as the period from the patient's admittance to the post-anesthesia care unit (PACU) to complete
recovery, because it encompasses the time needed for the patient to transition from a state of general anesthesia to full consciousness and
normal physiological function. This phase is critical as it requires continuous monitoring and care to ensure the patient's safety and prevent any
complications that may arise during the recovery process.
Question 4 NU 170 Exam 1
Elective Surgery
CORRECT ANSWER
Suggested and scheduled, no forseen ill effects if postponed
Rationale: This answer is correct because elective surgery refers to a medical procedure that is planned and scheduled in advance, rather than
being an emergency or urgent operation, allowing for preparation and minimizing risks. Since the surgery is anticipated and not a response to an
unexpected medical crisis, there are typically no unforeseen ill effects if the procedure is postponed.
,Question 5 NU 170 Exam 1
Urgent Surgery
CORRECT ANSWER
Necessary to be performed within 1 to 2 days (ASAP)
Rationale: The phrase "Necessary to be performed within 1 to 2 days (ASAP)" is correct because it implies a high level of urgency, indicating that
the surgery must be conducted in a short timeframe to prevent further complications or harm to the patient. This time constraint is characteristic
of urgent surgeries, which require immediate attention to alleviate critical conditions or alleviate severe symptoms.
Question 6 NU 170 Exam 1
Emergency Surgery
CORRECT ANSWER
Performed IMMEDIATELY; life or limb threatening
Rationale: This answer suggests a critical condition where every second counts, and immediate action is required to prevent severe harm or
death. In emergency surgery scenarios, prompt intervention is crucial to mitigate life-threatening injuries or conditions, making "Performed
IMMEDIATELY; life or limb threatening" a fitting description of the situation.
Question 7 NU 170 Exam 1
Ambulatory Admission
CORRECT ANSWER
Surgeries are performed that DONT require hospital admission; Outpatient procedure
Rationale: The term "Ambulatory Admission" refers to a type of healthcare setting where patients receive treatment and then are discharged
within the same day, without the need for an overnight hospital stay. This aligns with the concept of outpatient procedures, which are surgeries or
medical treatments conducted on an outpatient basis, allowing patients to recover at home rather than in a hospital.
Question 8 NU 170 Exam 1
Same Day Admission
CORRECT ANSWER
Admission of surgical patients to the hospital on the day of surgery
Rationale: Same Day Admission refers to the practice of admitting patients to the hospital on the same day as their scheduled surgical
procedure, allowing for streamlined logistics, reduced hospital stays, and optimized patient care. This approach is particularly beneficial for
patients undergoing elective surgeries, as it minimizes delays, reduces the risk of complications, and enables quicker recovery times.
, Question 9 NU 170 Exam 1
Early Admission
CORRECT ANSWER
Patient that may have multiple and/or significant comorbidities are admitted 1 to 2 days prior to surgery to maintain or prepare
Rationale: This correct answer reflects the standard medical practice of admitting patients with multiple and/or significant comorbidities a day or
two before surgery to allow for thorough pre-operative evaluation, optimization of their medical conditions, and preparation of the patient's overall
health for the upcoming surgery, thereby minimizing potential complications. This early admission enables healthcare providers to closely monitor
the patient's condition and make any necessary adjustments before the surgery, ultimately reducing the risk of adverse outcomes.
Question 10 NU 170 Exam 1
Diagnostic Surgery
CORRECT ANSWER
Surgical exploration that alows health care providers to confirm diagnoses ex: laparotomy
Rationale: Diagnostic surgery involves using surgical procedures to gather information and confirm a diagnosis, which is precisely what happens
during a laparotomy, allowing healthcare providers to visually inspect the internal organs and tissues. This type of surgical exploration enables
healthcare providers to directly observe the affected area, making it an essential tool in confirming diagnoses and guiding further treatment.
Question 11 NU 170 Exam 1
Curative Surgery
CORRECT ANSWER
Surgery performed to resolve a health problem by repairing or removing the cause
• Ex. Lap chole, Mastectomy, Hysterectomy
Rationale: This option is the correct answer because it specifically highlights surgeries that aim to resolve a health problem by directly
addressing and removing or repairing the underlying cause, which is the primary goal of curative surgery. The examples provided, such as Lap
chole, Mastectomy, and Hysterectomy, are all surgeries that involve removing or repairing a specific part of the body to cure a particular health
issue, aligning with the definition of curative surgery.
Question 12 NU 170 Exam 1
Palliative Surgery
CORRECT ANSWER
Surgery that improves comfort or reduces intensity of disease symptoms; will not produce cure (ex. colostomy, debridement of
necrotic tissue)
Rationale: Palliative surgery focuses on alleviating symptoms or improving the quality of life for patients with incurable diseases, rather than
aiming to cure the underlying condition. This type of surgery typically involves procedures that temporarily relieve pain, discomfort, or other
distressing symptoms, such as colostomy or debridement of necrotic tissue, which are not intended to cure the disease itself but rather to manage
its effects.
