Question 1 of 5
A client with anemia secondary to chronic kidney disease (CKD) started a prescription for epoetin alfa two months ago. Which client finding best indicates that the medication is effective? Reference Range: Hemoglobin (Hgb) [14 to 18 g/dL (8.7 to 11.2 mmol/L)]
Correct Answer: D
Rationale: Epoetin alfa stimulates red blood cell production, directly increasing hemoglobin levels. A rise to 12 g/dL, though below the male reference range, objectively indicates effectiveness in treating anemia. Dietary changes, subjective energy improvements, or iron therapy tolerance are less direct measures.
Question 2 of 5
The client is a 75-year-old female admitted to the preoperative area to prepare for pacemaker insertion. Client reports she is having this done because her heart rate has been staying very low, she is always tired, and she has passed out once from low heart rate. Client has history of worsening symptomatic bradycardia. History of atrial fibrillation controlled. The nurse is preparing the client's plan of care. Select 4 findings that would indicate to the nurse that the administration of the vancomycin antibiotic would be safe to administer.
Correct Answer: A,B,D,F
Rationale: No known allergies reduce allergic reaction risks. A large vein IV minimizes thrombophlebitis. Prophylactic use is appropriate for surgery. Safe dosage prevents toxicity. Potassium and BUN, while important, are less specific to vancomycin safety.
Question 3 of 5
A male client is admitted for observation because he is reporting progressively increasing fatigue over the past month and a brief episode of dizziness that occurred today. He has a history of heartburn and indigestion that he self-treats with ibuprofen and antacids. Which assessment finding should the nurse report immediately to the healthcare provider? Reference Ranges: Hemoglobin [14 to 18 g/dL (8.7 to 11.2 mmol/L)] Hematocrit [42% to 52% (0.42 to 0.52 volume fraction)] Gastric pH [1.5 to 3.5]
Correct Answer: C
Rationale: A positive guaiac test indicates occult blood, suggesting gastrointestinal bleeding, potentially from ibuprofen use, which exacerbates gastric irritation. This requires immediate reporting for evaluation, given the client’s fatigue and dizziness. Normal hematocrit, slightly low hemoglobin, and normal gastric pH are less urgent.
Question 4 of 5
A client has a prescription for heparin 1,000 units IV STAT. Several pre-filled syringes of low molecular weight heparin are available in the client's medication drawer. Which action should the nurse implement?
Correct Answer: B
Rationale: Standard heparin (IV) and low molecular weight heparin (LMWH, subcutaneous) are not interchangeable. Requesting standard heparin from the pharmacy ensures the correct medication and route, preventing dosing errors or inefficacy.
Question 5 of 5
The healthcare provider prescribes propylthiouracil (PTU) and Lugol's solution, a strong iodine solution, for a client with hyperthyroidism. How should the nurse schedule the administration of these medications?
Correct Answer: B
Rationale: Lugol’s solution reduces thyroid hormone production rapidly, preparing the gland for PTU, which inhibits hormone synthesis. Administering iodine one hour before PTU optimizes treatment efficacy. Meal timing, bedtime scheduling, or parenteral dosing are incorrect.
