UWORLD NCLEX-RN TEST 2
QUESTIONS AND ANSWERS 2027
1. A nurse is caring for a client with a suspected diagnosis of Diabetes Insipidus (DI). Which
laboratory finding should the nurse anticipate?
A. Urine specific gravity of 1.035
B. Serum sodium of 128 mEq/L
C. Urine specific gravity of 1.002
D. Serum osmolality of 270 mOsm/kg
Answer: C
Conceptual Explanation: Diabetes Insipidus is characterized by a deficiency of ADH,
leading to the excretion of large volumes of dilute urine. A low urine specific gravity
(typically less than 1.005) is a hallmark sign. High serum osmolality and hypernatremia are
expected, not hyponatremia or high specific gravity.
2. The nurse is monitoring a client receiving Magnesium Sulfate for preeclampsia. Which
assessment finding is most concerning?
A. Deep tendon reflexes of 2+
B. Respiratory rate of 10 breaths per minute
,C. Urine output of 40 mL per hour
D. Serum magnesium level of 6 mg/dL
Answer: B
Conceptual Explanation: Magnesium toxicity causes CNS depression. A respiratory rate
below 12 per minute, loss of deep tendon reflexes, and decreased urine output are signs of
toxicity. 6 mg/dL is within the therapeutic range (4-7 mg/dL).
3. A client with chronic heart failure is prescribed Digoxin. Which electrolyte imbalance most
significantly increases the risk for Digoxin toxicity?
A. Hypermagnesemia
B. Hypercalcemia
C. Hypokalemia
D. Hyponatremia
Answer: C
Conceptual Explanation: Hypokalemia (low potassium) potentiates the action of Digoxin
at the myocardial cell level, significantly increasing the risk of toxicity even if digoxin levels
are in the therapeutic range.
4. A client is admitted with Neuroleptic Malignant Syndrome (NMS). Which medication
should the nurse anticipate administering?
A. Benztropine
, B. Haloperidol
C. Dantrolene
D. Lithium
Answer: C
Conceptual Explanation: Dantrolene is a muscle relaxant used to treat the muscle rigidity
and hyperthermia associated with NMS. Bromocriptine may also be used. Benztropine is
for extrapyramidal symptoms, not NMS.
5. During a mass casualty incident, a nurse identifies a victim with a traumatic brain injury
who is unconscious and has agonal respirations. Which triage tag color is appropriate?
A. Red
B. Yellow
C. Green
D. Black
Answer: D
Conceptual Explanation: Black tags are for the deceased or those with injuries so
extensive they are not expected to survive given the care available during a disaster
(expectant). Agonal respirations in an unconscious TBI patient indicate a poor prognosis.
