Nursing Elites

1. A nurse is providing teaching to a client who has cirrhosis and a new prescription for lactulose. The nurse should instruct the client that lactulose has which of the following therapeutic effects?

• A. Increases blood pressure
• B. Prevents esophageal bleeding
• C. Decreases heart rate
• D. Reduces ammonia levels

Correct answer: D

Rationale: The correct answer is D: Reduces ammonia levels. Lactulose is used to reduce blood ammonia levels in clients with hepatic encephalopathy. Options A, B, and C are incorrect because lactulose does not have the therapeutic effect of increasing blood pressure, preventing esophageal bleeding, or decreasing heart rate.

2. A nurse is teaching a newly licensed nurse about contraindications to ceftriaxone. The nurse should include that a severe allergy to which of the following medications is a contraindication to ceftriaxone?

• A. Gentamicin
• B. Clindamycin
• C. Piperacillin
• D. Sulfamethoxazole-trimethoprim

Correct answer: C

Rationale: The correct answer is C. Ceftriaxone, a cephalosporin antibiotic, has a cross-sensitivity with penicillin antibiotics like piperacillin. Therefore, a severe allergy to penicillin or penicillin-related antibiotics would be a contraindication to ceftriaxone. Choices A, B, and D are incorrect because they are not associated with a known cross-sensitivity with ceftriaxone.

3. A nurse is planning to administer chlorothiazide 20 mg/kg/day PO divided equally and administered twice daily for a toddler who weighs 28.6 lb. The amount available is chlorothiazide oral suspension 250 mg/5 mL. How many mL should the nurse administer per dose? (Round to the nearest tenth)

• A. 2.6 mL
• B. 2.63 mL
• C. 2.7 mL
• D. 2.2 mL

Correct answer: A

Rationale: To find the dose per administration, first convert the toddler's weight to kg: 28.6 lb ÷ 2.2 = 13 kg. Then calculate the total daily dose: 20 mg/kg × 13 kg = 260 mg/day. Since it is divided into two doses, each dose is 130 mg. The concentration of the oral suspension is 250 mg/5 mL = 50 mg/mL. Therefore, to find the volume needed per dose, divide the dose by the concentration: 130 mg ÷ 50 mg/mL = 2.6 mL per dose. Hence, the nurse should administer 2.6 mL per dose. Choices B, C, and D are incorrect as they do not accurately calculate the dosage of chlorothiazide needed per dose based on the toddler's weight and the concentration of the oral suspension.

4. A nurse is providing teaching to a newly licensed nurse about metoclopramide. The nurse should include in the teaching that which of the following conditions is a contraindication to this medication?

• A. Hyperthyroidism
• B. Intestinal obstruction
• C. Glaucoma
• D. Low blood pressure

Correct answer: B

Rationale: The correct answer is B: Intestinal obstruction. Metoclopramide is contraindicated in clients with intestinal obstruction due to its prokinetic effects, which could exacerbate the condition. Choices A, C, and D are incorrect because metoclopramide is not contraindicated in hyperthyroidism, glaucoma, or low blood pressure. Hyperthyroidism, glaucoma, and low blood pressure are not specific contraindications for metoclopramide use, and this medication is commonly prescribed for conditions like gastroesophageal reflux disease and diabetic gastroparesis.

5. A client with rheumatoid arthritis is prescribed long-term prednisone therapy. What adverse effect should the client monitor for according to the nurse's instruction?

• A. Stress fractures
• B. Orthostatic hypotension
• C. Gingival ulcerations
• D. Weight loss

Correct answer: A

Rationale: The correct answer is A: Stress fractures. Long-term prednisone therapy can lead to osteoporosis, which increases the risk of stress fractures. Option B, orthostatic hypotension, is not a common adverse effect associated with prednisone use. Option C, gingival ulcerations, is more commonly associated with conditions like periodontal disease or poor oral hygiene rather than prednisone therapy. Option D, weight loss, is not a typical adverse effect of prednisone; in fact, weight gain is more common due to prednisone's impact on metabolism.
