NURS 511 MIDTERM EXAM COMPLETE QUESTIONS WITH ANSWERS
100% VERIFIED 2025 LATEST UPDATED ALREADY GRADED A+
Question 1
Which of the following best describes the role of an Advanced Practice Registered Nurse
(APRN) in advanced health assessment?
A) To collect basic patient history and vital signs.
B) To perform routine physical examinations as directed by a physician.
C) To conduct comprehensive, focused, and episodic assessments, integrating advanced
knowledge of pathophysiology and pharmacology.
D) To only assess patients with complex, chronic conditions.
E) To delegate all assessment tasks to registered nurses.
Correct Answer: C) To conduct comprehensive, focused, and episodic assessments,
integrating advanced knowledge of pathophysiology and pharmacology.
Rationale: APRNs utilize their expanded knowledge base to perform in-depth assessments
beyond the scope of a general registered nurse, allowing for more precise diagnostic
reasoning and intervention planning.
Question 2
During the initial assessment of an adult patient, the nurse practitioner palpates the apical
impulse. In a healthy adult, this impulse is typically located at the:
A) 2nd intercostal space, left midclavicular line.
B) 3rd intercostal space, right sternal border.
C) 5th intercostal space, left midclavicular line.
D) 4th intercostal space, right midclavicular line.
E) 6th intercostal space, anterior axillary line.
Correct Answer: C) 5th intercostal space, left midclavicular line.
Rationale: The apical impulse (point of maximal impulse, PMI) in most adults is normally
located at the fifth intercostal space in the left midclavicular line.
Question 3
A patient presents with sudden onset of excruciating, "tearing" chest pain radiating to the back.
On examination, there is a significant difference in blood pressure between the right and left
arms. The most critical differential diagnosis to consider is:
A) Myocardial Infarction.
B) Pericarditis.
C) Pneumothorax.
D) Pulmonary Embolism.
E) Aortic Dissection.
Correct Answer: E) Aortic Dissection.
Rationale: The sudden, severe, tearing chest pain radiating to the back, coupled with a
blood pressure differential between limbs, is highly classic for an acute aortic dissection,
which is a medical emergency.

Question 4
Which type of cellular adaptation involves an increase in the number of cells in a tissue or organ?
A) Hypertrophy
B) Atrophy
C) Metaplasia
D) Dysplasia
E) Hyperplasia
Correct Answer: E) Hyperplasia
Rationale: Hyperplasia is an increase in the number of cells, leading to an enlargement of
the tissue or organ, often in response to increased demand or hormonal stimulation.
Question 5
The process by which one mature cell type is replaced by another mature cell type, usually in
response to chronic irritation or inflammation, is called:
A) Hyperplasia
B) Hypertrophy
C) Atrophy
D) Dysplasia
E) Metaplasia
Correct Answer: E) Metaplasia
Rationale: Metaplasia is a reversible change where one differentiated cell type is replaced
by another differentiated cell type, often as an adaptive response to stress or chronic injury.
Question 6
A patient with chronic obstructive pulmonary disease (COPD) has persistent hypoxemia, which
leads to polycythemia. This is an example of which cellular adaptation?
A) Atrophy
B) Metaplasia
C) Dysplasia
D) Hyperplasia
E) Hypertrophy
Correct Answer: D) Hyperplasia
Rationale: Polycythemia, an increase in red blood cells, is a compensatory hyperplasia of
erythroid precursors in the bone marrow, stimulated by chronic hypoxemia in an attempt
to increase oxygen-carrying capacity.
Question 7
In a patient experiencing systemic inflammation, which of the following clinical findings is most
likely to be present?
A) Localized pain and redness only.
B) Decreased white blood cell count (leukopenia).
C) Fever and elevated erythrocyte sedimentation rate (ESR).
, [Type here]
D) Bradycardia and hypotension.
E) Hypoglycemia.
Correct Answer: C) Fever and elevated erythrocyte sedimentation rate (ESR).
Rationale: Fever (pyrexia) and elevated inflammatory markers such as ESR and C-reactive
protein (CRP) are systemic manifestations commonly seen with inflammation.
Question 8
Which type of hypersensitivity reaction is mediated by IgE antibodies and typically causes
immediate allergic responses like anaphylaxis or asthma?
A) Type II (Cytotoxic)
B) Type III (Immune Complex)
C) Type IV (Delayed-type)
D) Autoimmune
E) Type I (Immediate)
Correct Answer: E) Type I (Immediate)
Rationale: Type I hypersensitivity reactions are IgE-mediated, leading to mast cell
degranulation and the rapid release of inflammatory mediators (e.g., histamine), causing
immediate allergic symptoms.
Question 9
A patient with a penicillin allergy develops a rash, fever, and eosinophilia after taking a new
cephalosporin. This is most likely an example of:
A) Type I hypersensitivity.
B) Type II (Cytotoxic) hypersensitivity.
C) Type III (Immune Complex) hypersensitivity.
D) Type IV (Delayed-type) hypersensitivity.
E) Idiosyncratic drug reaction.
Correct Answer: B) Type II (Cytotoxic) hypersensitivity.
Rationale: Drug-induced hemolytic anemia, thrombocytopenia, or neutropenia, often
involving antibody-mediated destruction of blood cells, are examples of Type II
hypersensitivity. Some drug-induced rashes can also be Type II, although Type I and IV are
more common for many drug allergies.
Question 10
Which electrolyte imbalance is characterized by a prolonged PR interval, flattened T waves,
prominent U waves, and muscle weakness?
A) Hyperkalemia
B) Hypernatremia
C) Hypocalcemia
D) Hypokalemia
E) Hypomagnesemia
Correct Answer: D) Hypokalemia
