QUESTION 1
A nurse is performing a head-to-toe assessment on an adult client. Which of
the following techniques should the nurse use when assessing for lymph node
enlargement in the neck?
A) Apply firm, deep palpation using the heel of the hand
B) Use the fingertips to gently palpate in a circular motion along the
sternocleidomastoid muscles
C) Palpate using only one hand while stabilizing the head with the other
D) Have the client extend the neck fully backward during palpation
E) Use quick, jabbing motions to locate nodes
B) Use the fingertips to gently palpate in a circular motion along the
sternocleidomastoid muscles
,EXPERT RATIONALE: Proper technique for cervical lymph node assessment
involves using gentle, circular motions with the fingertips (not firm pressure) along
the sternocleidomastoid muscles where most cervical nodes are located. This
sensitive palpation technique allows for detection of node size, shape, and
consistency without causing discomfort. Options A, D, and E use incorrect
techniques that may cause discomfort or miss findings. Option C is incomplete as
bilateral comparison is important.
QUESTION 2
A nurse is assessing a client's respiratory status and auscultates fine crackles
in the bilateral lower lobes. What is the most likely pathophysiologic reason
for these findings?
A) Air trapping in small airways
B) Fluid accumulation in the alveoli
C) Constriction of the bronchial tubes
D) Pleural inflammation
E) Decreased lung elasticity
B) Fluid accumulation in the alveoli
EXPERT RATIONALE: Fine crackles heard on auscultation are caused by air passing
through small airways that contain fluid. This "popping" or "velcro-like" sound
occurs when alveoli fill with fluid, such as in pulmonary edema, pneumonia, or
pulmonary fibrosis. Air trapping produces wheezing, bronchial constriction
produces wheezing or diminished sounds, pleural inflammation produces friction
rubs, and decreased elasticity causes diminished breath sounds. The bilateral lower
lobe location is classic for pulmonary edema.
QUESTION 3
,During a physical assessment, a nurse notes that a client's pupils are unequal
in size. What is the most appropriate initial nursing action?
A) Immediately notify the physician of a potential neurological emergency
B) Document the finding and compare with previous assessments
C) Perform a complete neurological assessment and check for anisocoria history
D) Apply artificial tears to the eye with the larger pupil
E) Dim the room lights to see if pupils equalize
C) Perform a complete neurological assessment and check for anisocoria
history
EXPERT RATIONALE: Unequal pupils (anisocoria) can be pathological or benign.
Before assuming emergency, the nurse should perform a complete neurological
assessment including pupillary response to light and accommodation, extraocular
movements, and other neurological signs. It's essential to determine if the client
has chronic anisocoria (which may be normal for that individual) by checking
previous assessments or asking the client directly. Only after ruling out benign
causes and finding other neurological deficits would immediate physician
notification be warranted.
QUESTION 4
A nurse is preparing to administer an intramuscular injection to an adult
client. Which anatomical site would be the BEST choice for a routine IM
injection?
A) Vastus lateralis muscle
B) Gluteus maximus muscle
C) Deltoid muscle
D) Rectus femoris muscle
E) Biceps muscle
, A) Vastus lateralis muscle
EXPERT RATIONALE: The vastus lateralis (lateral thigh muscle) is the preferred site
for routine IM injections in adults because it is large, well-developed, has good
blood supply, and is located away from major nerves and blood vessels. While the
gluteus maximus can be used, it is associated with higher risk of sciatic nerve injury
if not located properly. The deltoid is too small for most IM injections. The rectus
femoris, though safe, is less preferred than vastus lateralis. The biceps is not used
for IM injections.
QUESTION 5
A nurse is documenting a client's skin assessment and notes a lesion that is
nonblanching, red-purple in color, and does not blanch with pressure. What
type of lesion is this most consistent with?
A) Macule
B) Petechiae
C) Wheal
D) Vesicle
E) Papule
B) Petechiae
EXPERT RATIONALE: Petechiae are small (1-3mm), flat, red-purple lesions that do
not blanch with pressure and represent capillary bleeding into the skin. The
nonblanching quality is key to distinguishing petechiae from other lesions. Macules
are flat, nonpalpable lesions that blanch. Wheals are raised, edematous lesions.
Vesicles are fluid-filled blisters. Papules are small, raised, solid lesions. The
nonblanching characteristic and red-purple color are diagnostic for petechiae.
