Nursing Elites

1. 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.

2. A nurse is reviewing laboratory values for a client who reports fatigue and cold intolerance. The client has an increased thyroid stimulating hormone (TSH) level and a decreased total T3 and T4 level. The nurse should anticipate a prescription for which of the following medications?

• A. Methimazole
• B. Somatropin
• C. Levothyroxine
• D. Propylthiouracil

Correct answer: C

Rationale: Levothyroxine is the correct answer. In this scenario, the client's elevated TSH and decreased T3 and T4 levels indicate hypothyroidism, a condition where the thyroid gland does not produce enough hormones. Levothyroxine is a synthetic form of thyroid hormone that is used to replace or supplement the body's naturally produced thyroid hormones. Methimazole and Propylthiouracil are used to treat hyperthyroidism by reducing the production of thyroid hormones. Somatropin is a growth hormone used to treat growth hormone deficiency and other conditions unrelated to thyroid disorders.

3. 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.

4. A healthcare professional is reviewing the laboratory results for a client who has a prescription for filgrastim. The healthcare professional should recognize that an increase in which of the following values indicates a therapeutic effect of this medication?

• A. Erythrocyte count
• B. Neutrophil count
• C. Lymphocyte count
• D. Thrombocyte count

Correct answer: B

Rationale: Filgrastim is a medication used to stimulate the production of neutrophils in patients with neutropenia. Neutrophils are a type of white blood cell that plays a crucial role in fighting off infections. Therefore, an increase in neutrophil count would indicate a therapeutic effect of filgrastim. The other options, such as erythrocyte count (red blood cells), lymphocyte count, and thrombocyte count (platelets), are not directly affected by filgrastim and would not indicate a therapeutic effect of this medication.

5. A nurse is administering subcutaneous heparin to a client who is at risk for deep vein thrombosis. Which of the following actions should the nurse take?

• A. Administer the medication into the client's abdomen.
• B. Inject the medication into a muscle.
• C. Massage the site after administering the medication.
• D. Use a 22-gauge needle to administer the medication.

Correct answer: A

Rationale: Heparin is best absorbed and less likely to cause hematomas when administered into subcutaneous tissue, specifically the abdomen, which is a common site for subcutaneous injections. Injecting heparin into a muscle (Choice B) is incorrect as it should be administered subcutaneously. Massaging the site after administering the medication (Choice C) is contraindicated as it can cause tissue damage or bruising. Using a 22-gauge needle (Choice D) is not recommended for subcutaneous injections of heparin; a smaller needle size such as 25-26 gauge is preferred for subcutaneous administration.
