UWORLD NCLEX-RN TEST 2 EXAM
QUESTIONS AND ANSWERS
1. A client with chronic heart failure is prescribed digoxin. Which assessment finding is most
concerning to the nurse?
A. Occasional premature ventricular contractions (PVCs)
B. Heart rate of 62 beats per minute
C. Visual disturbances such as yellow-green halos
D. Client report of feeling tired and weak
Answer: C
Conceptual Explanation: Visual disturbances, including yellow-green halos, are classic
signs of digoxin toxicity. Other signs include nausea, vomiting, and cardiac arrhythmias.
While fatigue is common in HF, halos are specific for toxicity.
2. The nurse is caring for a client with Type 1 Diabetes Mellitus who is unresponsive. A
fingerstick glucose reveals 42 mg/dL. Which action should the nurse take first?
A. Administer 15g of oral glucose gel
B. Notify the healthcare provider
,C. Administer 50% Dextrose IV push
D. Recheck the blood glucose in 15 minutes
Answer: C
Conceptual Explanation: For an unresponsive client with hypoglycemia, IV 50% Dextrose
is the priority. Oral carbohydrates are only for conscious clients who can swallow safely.
3. Which client should the charge nurse assign to a Licensed Practical Nurse (LPN)?
A. A client with a new diagnosis of Guillain-Barre syndrome
B. A client being admitted from the ED for a suspected MI
C. A client with a chest tube who has sudden onset of shortness of breath
D. A client 2 days postoperative hip replacement needing dressing changes
Answer: D
Conceptual Explanation: LPNs can perform tasks for stable clients with predictable
outcomes, such as routine dressing changes. New diagnoses, instability, and admissions
require the assessment skills of an RN.
4. A client is diagnosed with SIADH. Which laboratory result should the nurse expect?
A. Serum osmolality of 310 mOsm/kg
B. Serum sodium of 128 mEq/L
C. Urine specific gravity of 1.005
, D. Hematocrit of 55%
Answer: B
Conceptual Explanation: SIADH causes water retention and dilutional hyponatremia.
Expected findings include low serum sodium, low serum osmolality, and high urine specific
gravity.
5. A client with a history of asthma is admitted with acute respiratory distress. Which
assessment finding requires immediate intervention?
A. Audible expiratory wheezing
B. Silent chest on auscultation
C. Presence of a nonproductive cough
D. Use of accessory muscles during inspiration
Answer: B
Conceptual Explanation: A ‘silent chest’ indicates that air movement has ceased,
representing a life-threatening emergency (status asthmaticus). Wheezing is better than no
sound at all.
6. The nurse is assessing a client with acute cholecystitis. Where does the nurse expect the
client to report pain?
A. Right upper quadrant radiating to the right shoulder
B. Left upper quadrant radiating to the back
