1. A nurse is assessing a client with a sodium level of 128
mEq/L. Which finding should the nurse expect?
A. Hyperreflexia
B. Muscle twitching
C. Nausea and malaise
D. Decreased deep tendon reflexes
Answer: C. Nausea and malaise
Rationale: Hyponatremia (Na <135 mEq/L) causes cellular
swelling. Early symptoms include nausea, malaise, headache, and
confusion. Hyperreflexia and twitching occur in hypernatremia or
hypocalcemia.

,2. A client has a potassium level of 2.9 mEq/L. Which ECG
change is most concerning?
A. Tall peaked T waves
B. Prolonged PR interval with U waves
C. Wide QRS complex
D. ST segment elevation
Answer: B. Prolonged PR interval with U waves
Rationale: Hypokalemia (K <3.5) causes flattened T waves and
prominent U waves. Tall peaked T waves and wide QRS are
seen in hyperkalemia.
3. A nurse is infusing 40 mEq of potassium chloride in 1000
mL of normal saline. Which action is correct?
A. Give as an IV push over 5 minutes
B. Set the IV pump to run at 200 mL/hr
2
,C. Ensure the client has a urinary output of at least 30 mL/hr
D. Use a filter needle for administration
Answer: C. Ensure the client has a urinary output of at least
30 mL/hr
Rationale: IV potassium requires urine output ≥30 mL/hr to
prevent hyperkalemia. Never give K+ IV push; max rate is 10-
20 mEq/hr. Filter needle not required.
4. Which client is at highest risk for hypercalcemia?
A. Client with chronic kidney disease
B. Client taking loop diuretics
C. Client with metastatic breast cancer
D. Client with severe burns
Answer: C. Client with metastatic breast cancer
Rationale: Malignancies (bone metastases, multiple myeloma)
3
, cause hypercalcemia via bone resorption. CKD causes
hypocalcemia. Loop diuretics cause hypocalcemia.
5. A client’s magnesium level is 1.0 mEq/L (low). What
assessment takes priority?
A. Deep tendon reflexes
B. Bowel sounds
C. Lung sounds
D. Gag reflex
Answer: A. Deep tendon reflexes
Rationale: Hypomagnesemia (Mg <1.5) causes hyperreflexia,
tetany, seizures. Assess DTRs first. Hyporeflexia occurs with
hypermagnesemia.
6. Which IV fluid is isotonic and will remain in the vascular
space?
