Question 1 of 5
A client with generalized anxiety disorder (GAD) receives a new prescription for lorazepam. Which statement provided by the client requires additional instruction by the nurse?
Correct Answer: B
Rationale: Lorazepam may take time for optimal effect, and stopping abruptly risks withdrawal or worsening anxiety. Clients should continue as prescribed and consult their provider if effects are lacking. Relaxation techniques, avoiding sedatives, and moving slowly are appropriate.
Question 2 of 5
A client with peptic ulcer disease receives a new prescription for cimetidine. Which statement provided by the client requires additional instruction by the nurse?
Correct Answer: B
Rationale: Smoking exacerbates peptic ulcers and impairs healing. Reducing to a pack daily is insufficient; quitting is ideal. Notifying about lethargy, monitoring sexual dysfunction, and timing with antacids are appropriate.
Question 3 of 5
The nurse is providing medication teaching to a client with bipolar disorder who receives a prescription for lithium carbonate. Which instruction should the nurse emphasize with the client?
Correct Answer: C
Rationale: Adequate fluid intake (1500-3000 mL/day) prevents dehydration, which can elevate lithium levels and risk toxicity. Taking with food, reviewing fliers, or reporting weight changes are less critical to lithium safety.
Question 4 of 5
The nurse is caring for an adult client who is taking digoxin. Which laboratory value should be reported to the healthcare provider immediately? Reference Range: Sodium [Adult 136 to 145 mEq/L (136 to 145 mmol/L)] Digoxin level [0.8 to 2.0 ng/mL (0.6 to 13 nmol/L)] Potassium (K+) [Adult: 3.5 to 5.0 mEq/L (3.5 to 5.0 mmol/L)] Creatinine [0.5 to 1.1 mg/dL (44 to 97 μmol/L)]
Correct Answer: C
Rationale: Hypokalemia (3.2 mEq/L) increases digoxin toxicity risk, potentially causing arrhythmias. Immediate reporting allows potassium correction. Therapeutic digoxin, normal creatinine, and mild hyponatremia are less urgent.
Question 5 of 5
The nurse is administering sodium polystyrene sulfonate to a client in acute kidney injury (AKI). Which laboratory finding indicates that the medication has been effective? Reference Range: Glucose [74 to 106 mg/dL (4.1 to 5.9 mmol/L)] Hemoglobin [14 to 18 g/dL (140 to 180 g/L)] Potassium [3.5 to 5 mEq/L (3.5 to 5 mmol/L)] Ammonia [10 to 80 μg/dL (6 to 47 μmol/L)]
Correct Answer: C
Rationale: Sodium polystyrene sulfonate lowers potassium by exchanging sodium for potassium in the gut. A potassium level of 3.8 mEq/L (normal range) indicates effective hyperkalemia treatment in AKI. Ammonia, hemoglobin, and glucose are unaffected by this medication.
