Nursing Elites

1. 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.

2. A nurse is preparing to administer prochlorperazine 2.5 mg IV. Available is prochlorperazine injection 5 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest tenth)

• A. 0.5 mL
• B. 0.005 mL
• C. 0.05 mL
• D. 5 mL

Correct answer: A

Rationale: To calculate the mL needed, set up a proportion: 5 mg / 1 mL = 2.5 mg / X mL. Cross multiply to find X: 5 * X = 2.5 * 1, X = 2.5 / 5 = 0.5 mL. Therefore, the nurse should administer 0.5 mL. Choice B, 0.005 mL, is incorrect as it doesn't match the calculated result. Choice C, 0.05 mL, is incorrect as it is ten times the correct value. Choice D, 5 mL, is incorrect as it represents the total volume of the entire vial, not the amount needed for the specific dose.

3. A nurse is caring for a client who has a new prescription for enalapril. The nurse should monitor the client for which of the following adverse effects of this medication?

• A. Ecchymosis
• B. Jaundice
• C. Hypotension
• D. Hypokalemia

Correct answer: C

Rationale: The correct answer is C: Hypotension. Enalapril, an ACE inhibitor, can lead to hypotension, especially after the first dose. Choices A, B, and D are incorrect because enalapril is not typically associated with ecchymosis, jaundice, or hypokalemia as common adverse effects. Therefore, the nurse should primarily monitor the client for signs of hypotension.

4. A nurse is preparing to administer ampicillin 500 mg in 50 ml of dextrose 5% in water (D5W) to infuse over 15 min. The drop factor of the manual IV tubing is 10 gtt/mL. How many gtt/min should the nurse set the manual IV infusion to deliver? (Round to the nearest whole number)

• A. 33 gtt/min
• B. 66 gtt/min
• C. 10 gtt/min
• D. 14 gtt/min

Correct answer: A

Rationale: To calculate the IV flow rate, you multiply the drop factor (10 gtt/mL) by the volume to be infused per minute (50 mL / 15 min). This gives you 10 gtt/mL × 50 mL / 15 min = 33.33. Rounding to the nearest whole number, the nurse should set the manual IV infusion to deliver 33 gtt/min. Choice B (66 gtt/min) is incorrect as it is the result of doubling the correct answer. Choice C (10 gtt/min) is incorrect as it only considers the drop factor without accounting for the volume to be infused. Choice D (14 gtt/min) is incorrect as it miscalculates the infusion rate based on the given information.

5. 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.
