SECTION 1: NURSING PROCESS & CRITICAL THINKING (Exam 2) — Questions 1–25
, Page 2 of 69
1. The nurse is performing a head-to-toe assessment on a patient admitted for
pneumonia. When assessing the thorax, the nurse notes the anteroposterior (AP)
diameter appears equal to the lateral diameter. Which action should the nurse take
first?
A) Document this as a normal finding for the patient's age
B) Auscultate breath sounds in all lung fields
C) Notify the provider immediately of barrel chest deformity
D) Palpate for tactile fremitus
Answer: B
Rationale: An AP diameter equal to the lateral diameter (1:1 ratio) indicates a barrel
chest, commonly seen in patients with COPD or chronic respiratory conditions. The
nurse must first complete a comprehensive respiratory assessment by auscultating
breath sounds before determining significance.
2. Which statement best describes the nursing process?
A) A linear process that ends with evaluation
B) A cyclical, dynamic process that guides nursing care
C) A process used only for medical diagnoses
D) A process that does not require reassessment
Answer: B
Rationale: The nursing process is a cyclical, dynamic process that guides nursing care.
It includes Assessment, Diagnosis, Planning, Implementation, and Evaluation (ADPIE).
3. Data defined as what the patient says is which type of data?
A) Objective data
B) Subjective data
C) Secondary data
D) Tertiary data
Answer: B
Rationale: Subjective data is what the patient reports or says, such as pain level or
nausea.
4. Data defined as what is observed by the nurse is which type of data?
A) Subjective data
B) Objective data
C) Primary data
D) Secondary data
Answer: B
Rationale: Objective data is what the nurse observes through assessment, such as vital
signs, wound appearance, or lung sounds.
5. The nurse obtains information directly from the patient. This is which kind of
source?
, Page 3 of 69
A) Secondary source
B) Primary source
C) Tertiary source
D) Ancillary source
Answer: B
Rationale: The patient is the primary source of information. Family members and other
providers are secondary sources.
6. "Acute pain related to surgical incision, as evidenced by patient pain rating 8/10
and pain behaviors" is an example of which type of diagnosis?
A) Risk for diagnosis
B) Health promotion diagnosis
C) Actual diagnosis
D) Syndrome diagnosis
Answer: C
Rationale: An actual diagnosis describes a current problem that is present and
supported by defining characteristics.
7. "Risk for fall, related to diminished lower extremity strength" is an example of
which type of diagnosis?
A) Actual diagnosis
B) Risk for diagnosis
C) Health promotion diagnosis
D) Syndrome diagnosis
Answer: B
Rationale: A risk for diagnosis describes a vulnerability for developing a problem in the
absence of interventions.
8. "Readiness for enhanced nutrition, related to blood sugar control, as evidenced
by patient asking questions regarding diet recommendations" is an example of
which type of diagnosis?
A) Actual diagnosis
B) Risk for diagnosis
C) Health promotion diagnosis
D) Syndrome diagnosis
Answer: C
Rationale: A health promotion diagnosis describes a patient's readiness to enhance a
specific health behavior.
9. Which phase of the nursing process involves the systematic collection of
subjective and objective data?
A) Planning
B) Assessment
, Page 4 of 69
C) Implementation
D) Evaluation
Answer: B
Rationale: Assessment is the first step of the nursing process and involves systematic
collection of patient data.
10. The nurse is documenting a client's vital signs. Which documentation is most
appropriate?
A) "Vital signs stable"
B) "Temp 98.6°F, HR 72, RR 16, BP 118/76"
C) "Vitals look good"
D) "Patient appears stable"
Answer: B
Rationale: Documentation should include specific, measurable values rather than
vague descriptions.
11. Which statement best describes Tanner's Model of Clinical Judgment?
A) A linear process of decision-making
B) A model describing how nurses notice, interpret, respond, and reflect
C) A medical diagnosis framework
D) A medication administration protocol
Answer: B
Rationale: Tanner's Model describes clinical judgment as a cyclical process involving
noticing, interpreting, responding, and reflecting.
12. This type of interview asks specific questions and is nurse-controlled.
A) Non-directive interview
B) Directive interview
C) Focused interview
D) Open-ended interview
Answer: B
Rationale: A directive interview is nurse-controlled and used to gain specific
information when time is limited.
13. This type of interview is patient-controlled and focuses on rapport building.
A) Directive interview
B) Non-directive interview
C) Focused interview
D) Structured interview
Answer: B
Rationale: A non-directive interview is patient-controlled and focuses on building
rapport and exploring concerns.
