An adult patient's normal white blood cell (WBC) count is generally
within which range?
A. 1,500–3,500/mm³
B. 5,000–10,000/mm³
C. 11,000–15,000/mm³
D. 15,000–20,000/mm³
Answer: B. 5,000–10,000/mm³
Rationale: In adults, a normal WBC count is approximately 5,000–
10,000/mm³. WBCs are essential components of the immune system
and help the body fight infection and other abnormal processes.
Which WBC range is expected in a healthy newborn?
A. 2,000–5,000/mm³
B. 5,000–10,000/mm³
C. 9,000–30,000/mm³
D. 30,000–50,000/mm³
Answer: C. 9,000–30,000/mm³
,Rationale: Newborns normally have higher WBC counts than adults.
A range of approximately 9,000–30,000/mm³ can be expected during
the neonatal period.
Which RBC range is considered typical for an adult male?
A. 4.7–6.1 million/mm³
B. 3.0–4.0 million/mm³
C. 6.5–8.0 million/mm³
D. 2.0–3.5 million/mm³
Answer: A. 4.7–6.1 million/mm³
Rationale: Adult males generally have an RBC count of approximately
4.7–6.1 million/mm³. RBCs transport oxygen throughout the body
through their hemoglobin content.
Which RBC range is generally expected in an adult female?
A. 2.5–3.5 million/mm³
B. 3.0–4.0 million/mm³
C. 5.5–7.0 million/mm³
D. 4.2–5.4 million/mm³
Answer: D. 4.2–5.4 million/mm³
Rationale: A typical adult female RBC count is approximately 4.2–5.4
million/mm³. Reference ranges may vary slightly among laboratories.
,Which cranial nerve is responsible for the sense of smell?
A. Cranial nerve I
B. Cranial nerve II
C. Cranial nerve V
D. Cranial nerve VII
Answer: A. Cranial nerve I
Rationale: Cranial nerve I is the olfactory nerve. It is responsible for
the sense of smell. During assessment, the nurse may test each nostril
separately while the patient's eyes are closed.
Which assessment is most appropriate for evaluating cranial nerve II?
A. Asking the patient to shrug the shoulders
B. Testing visual acuity with a Snellen chart
C. Assessing the gag reflex
D. Asking the patient to clench the teeth
Answer: B. Testing visual acuity with a Snellen chart
Rationale: Cranial nerve II, the optic nerve, is responsible for vision.
Visual acuity can be assessed using a Snellen chart for distance vision
and a near-vision test for small print.
Which cranial nerve controls pupil constriction and contributes to
most eye movements?
, A. Cranial nerve IV
B. Cranial nerve V
C. Cranial nerve III
D. Cranial nerve VI
Answer: C. Cranial nerve III
Rationale: Cranial nerve III is the oculomotor nerve. It controls most
extraocular movements and is involved in pupil constriction.
Assessment includes pupil size, reaction to light, and eye movement.
Which cranial nerve is primarily associated with downward and
inward movement of the eye?
A. Cranial nerve II
B. Cranial nerve III
C. Cranial nerve VI
D. Cranial nerve IV
Answer: D. Cranial nerve IV
Rationale: Cranial nerve IV is the trochlear nerve. It innervates the
superior oblique muscle, which contributes to downward and inward
movement of the eye. Cranial nerves III, IV, and VI are commonly
assessed together during an eye-movement examination.
Which cranial nerve is assessed by evaluating facial sensation and the
muscles used for chewing?
