Nursing Elites

1. A nurse is preparing to administer amoxicillin 250 mg liquid suspension PO every 8 hr to an older adult client. The amount available is amoxicillin 50 mg/mL. How many mL should the nurse administer per dose? (Round the answer to the nearest whole number)

• A. 5 mL
• B. 6 mL
• C. 4 mL
• D. 7 mL

Correct answer: A

Rationale: To calculate the amount of amoxicillin in mL needed per dose, we can use the formula: 50 mg/mL = 250 mg / X mL. Cross multiply to solve for X: 50X = 250. Divide both sides by 50 to find X, which equals 5 mL per dose. Therefore, the nurse should administer 5 mL of amoxicillin per dose. Choice B, 6 mL, is incorrect as it does not match the calculated result. Choice C, 4 mL, is incorrect as it is too low based on the calculation. Choice D, 7 mL, is incorrect as it is too high based on the calculation.

2. 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.

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 nurse in an outpatient facility is assessing a client who is prescribed furosemide 40mg daily, but the client reports she has been taking extra doses to promote weight loss. Which of the following indicates she is dehydrated?

• A. Urine specific gravity of 1.035
• B. Urine specific gravity of 444
• C. Urine specific gravity of 2000
• D. Urine specific gravity of 1111.1

Correct answer: A

Rationale: A urine specific gravity greater than 1.030 indicates dehydration. In this case, a urine specific gravity of 1.035 suggests concentrated urine, indicating dehydration. Choices B, C, and D have values that are not within the normal range for urine specific gravity and do not indicate dehydration. A urine specific gravity of 444, 2000, or 1111.1 are not physiologically possible values and are therefore incorrect.

5. A nurse is preparing to administer an enteral tube feeding through an NG tube at 250 mL over 4 hr. The nurse should set the pump to deliver how many mL/hr? (Round the answer to the nearest whole number)

• A. 63 mL/hr
• B. 36 mL/hr
• C. 78 mL/hr
• D. 90 mL/hr

Correct answer: A

Rationale: To calculate the rate for the enteral tube feeding, divide the total volume by the total time: 250 mL / 4 hr = 62.5 ≈ 63 mL/hr. Therefore, the nurse should set the pump to deliver 63 mL/hr. Choices B, C, and D are incorrect as they do not match the correct calculation result. B is too low, C is too high, and D is also too high based on the correct calculation.
