Question 1 of 5

A client with eczema receives a prescription for betamethasone cream. Which client statement indicates to the nurse that further teaching is needed?

Correct Answer: C

Rationale: Occlusive dressings increase betamethasone absorption, risking side effects like skin thinning, and are not routinely recommended unless prescribed. Using on intact skin, limiting to 2 weeks, and avoiding sunlight are appropriate.

Question 2 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?

A. Offer both drugs together with a meal. B. Administer iodine one hour before PTU. C. Schedule both medications at bedtime. D. Give parental dose once every 24 hours.

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.

Question 3 of 5

The nurse is teaching a client how to use an inhaler device. Which client statement indicates to the nurse that the client understands the instructions?

A. The inhaler will be used before bed each night. B. Rinsing the mouth with water should be done after each use. C. Caffeinated beverages should be limited to two cups per day. D. To mask taste of the medication, inhaler can be used during meals.

Correct Answer: B

Rationale: Rinsing the mouth after inhaler use, especially with corticosteroids, prevents oral thrush by removing residual medication. Bedtime-only use, meal timing, or caffeine limits are incorrect and unrelated to proper inhaler technique.

Question 4 of 5

A client receives a prescription for ciprofloxacin 400 mg intravenously (IV) every 12 hours to be infused over an hour. The IV bag contains ciprofloxacin 400 mg in dextrose 5% in water (D5W) 200 mL. The nurse should program the infusion pump to deliver how many mL/hr? (Enter numerical value only.)

Your Answer:

Correct Answer: 200

Rationale: Infusion rate = 200 mL ÷ 1 hour = 200 mL/hr. The pump should be set to deliver 200 mL/hr to infuse the entire dose over one hour.

Question 5 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)]

A. Food diary shows increased consumption of iron-rich foods. B. Reports of increased energy levels and decreased fatigue. C. Takes concurrent iron therapy without adverse effects. D. Hemoglobin level increased to 12 g/dL (7.45 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.
