Question 1 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, enhancing PTU’s inhibition of hormone synthesis. Administering iodine one hour before PTU optimizes efficacy. Bedtime, parenteral, or meal-time administration are incorrect.
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 impairs ulcer healing. Reducing to a pack daily is insufficient; quitting is ideal. Monitoring sexual dysfunction, reporting lethargy, and timing with antacids are appropriate.
Question 3 of 5
A client is admitted for observation with reports of progressively increasing fatigue over the past month and a brief episode of dizziness that occurred today. The client has a history of heartburn and indigestion that is self-treated with ibuprofen and antacids. Which assessment finding should the nurse report immediately to the healthcare provider? Reference Range: Guaiac stool [negative] Hemoglobin [14 to 18 g/dL (140 to 180 g/L)] Hematocrit [42% to 52% (0.42 to 0.52 volume fraction)] Gastric Acid pH [1.5 to 3.5]
Correct Answer: A
Rationale: Positive guaiac indicates occult blood, suggesting GI bleeding possibly from ibuprofen. This requires immediate reporting given fatigue and dizziness. Normal hematocrit, gastric pH, and mild anemia are less urgent.
Question 4 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, enhancing PTU’s inhibition of hormone synthesis. Administering iodine one hour before PTU optimizes efficacy. Bedtime, parenteral, or meal-time administration are incorrect.
Question 5 of 5
The nurse administers the initial dose of cefoxitin to a client whose medical record indicates an allergy to penicillin. Which finding is most important for the nurse to report to the healthcare provider?
Correct Answer: B
Rationale: Pruritis and rash suggest a possible allergic reaction to cefoxitin, a cephalosporin, due to cross-reactivity with penicillin. This requires immediate reporting. Renal output, GI symptoms, and vaginal discharge are less specific to allergic responses.
