Graded Walden University. Every item uses a focused exam
stem, four response options, a keyed response, and a clear
rationale, making it easier to understand the subject, spot
distractors, and build real exam confidence.

, Question 1
A client with a serum potassium of 6.8 mEq/L has received IV regular insulin
with dextrose. Which finding best indicates the therapy is achieving its
intended physiologic effect?
A. Serum potassium has decreased without a change in total body
potassium.
B. Serum potassium has decreased with a corresponding increase in
urinary potassium excretion.
C. Serum glucose has normalized and potassium has increased.
D. Serum potassium has decreased and arterial pH has fallen.
Correct Answer: A - Serum potassium has decreased without a
change in total body potassium.
RATIONALE
Insulin shifts potassium intracellularly, lowering serum potassium
without removing it from the body; total body potassium is
unchanged. Enhanced renal excretion (B) reflects elimination rather
than shift, glucose normalization with rising potassium (C) is opposite
to the expected effect, and a falling pH (D) would worsen
hyperkalemia by driving potassium out of cells.
Question 2
Which assessment finding most strongly suggests that a client receiving
continuous bladder irrigation after transurethral resection of the prostate has
developed clot retention?
A. Returned irrigant is pale pink and equal to the instilled volume.
B. Returned irrigant is bright red with decreased output and suprapubic
pain.
C. The client reports a strong urge to void and passes clear urine around
the catheter.
D. The drainage bag contains dark amber urine with sediment.
Page 2
,Correct Answer: B - Returned irrigant is bright red with
decreased output and suprapubic pain.
RATIONALE
Clot retention obstructs outflow, causing bright red return, reduced
drainage relative to irrigation, and suprapubic distention or pain. Equal
pale pink return (A) indicates patency, clear urine around the catheter
(C) suggests bypass rather than retention, and dark amber sediment
(D) is unrelated to acute clot obstruction.
Question 3
In a client with acute decompensated heart failure, which set of findings best
represents a compensatory mechanism that is ultimately maladaptive?
A. Increased renin release leading to sodium and water retention.
B. Baroreceptor-mediated parasympathetic activation causing
bradycardia.
C. Increased atrial natriuretic peptide causing diuresis.
D. Decreased antidiuretic hormone release causing dilute urine.
Correct Answer: A - Increased renin release leading to sodium
and water retention.
RATIONALE
Reduced renal perfusion activates the renin-angiotensin-aldosterone
system, which retains sodium and water and worsens volume overload
and afterload - a compensatory response that becomes maladaptive.
Parasympathetic bradycardia (B), ANP-mediated diuresis (C), and
suppressed ADH (D) are either not the dominant response or are
beneficial, not maladaptive.
Question 4
A client prescribed lithium carbonate reports several days of vomiting and
diarrhea. Which laboratory result is most critical to evaluate before the next
dose?
Page 3
, A. Serum sodium of 138 mEq/L
B. Serum lithium level of 1.9 mEq/L
C. Serum creatinine of 0.8 mg/dL
D. Fasting blood glucose of 96 mg/dL
Correct Answer: B - Serum lithium level of 1.9 mEq/L
RATIONALE
Volume depletion from vomiting and diarrhea concentrates lithium
and impairs excretion, so a level of 1.9 mEq/L exceeds the therapeutic
range (0.6-1.2 mEq/L) and signals toxicity risk. Normal sodium (A),
creatinine (C), and glucose (D) do not indicate immediate danger,
though dehydration can still raise lithium levels.
Question 5
During the fourth stage of labor, which finding should the nurse report
immediately as a sign of potential postpartum hemorrhage?
A. Fundus firm at the umbilicus with moderate lochia rubra.
B. Fundus boggy and deviated to the right, above the umbilicus.
C. Lochia serosa with a small amount of perineal edema.
D. Blood pressure 118/76 mm Hg with pulse 88 beats/min.
Correct Answer: B - Fundus boggy and deviated to the right,
above the umbilicus.
RATIONALE
A boggy, right-deviated fundus suggests a full bladder displacing the
uterus and preventing contraction, which can lead to hemorrhage and
requires immediate intervention. A firm fundus (A) is expected, serosa
(C) occurs later, and stable vital signs (D) are reassuring.
Question 6
A client with a new colostomy has a stoma that is dusky blue and dry. Which
action should the nurse take first?
