Nursing Elites

1. 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.

2. A healthcare professional is planning to administer diltiazem via IV bolus to a client who has atrial fibrillation. When assessing the client, the healthcare professional should recognize that which of the following findings is a contraindication to the administration of diltiazem?

• A. Hypotension
• B. Tachycardia
• C. Decreased level of consciousness
• D. History of diuretic use

Correct answer: A

Rationale: Diltiazem, a calcium channel blocker, can cause hypotension. Administering it to a client who already has hypotension could exacerbate this condition. Therefore, hypotension is a contraindication to the administration of diltiazem. Incorrect Choices: B) Tachycardia is not a contraindication for administering diltiazem in atrial fibrillation as it is commonly used to control the heart rate. C) Decreased level of consciousness may require evaluation but is not a direct contraindication to diltiazem administration. D) History of diuretic use is not a contraindication if the client is not currently experiencing hypotension.

3. A nurse is caring for a client who has been taking isoniazid and rifampin for 3 weeks for the treatment of active pulmonary tuberculosis (TB). The client reports his urine is an orange color. Which of the following statements should the nurse make?

• A. Stop taking the isoniazid for 3 days and the discoloration should go away.
• B. Rifampin can turn body fluids orange.
• C. I'll make an appointment for you to see the provider this afternoon.
• D. Isoniazid can cause bladder irritation.

Correct answer: B

Rationale: The correct answer is B: 'Rifampin can turn body fluids orange.' Rifampin is known to cause orange discoloration of body fluids, including urine. This side effect is harmless and does not indicate a need to stop the medication. Choice A is incorrect because stopping isoniazid will not resolve the orange urine discoloration caused by rifampin. Choice C is unnecessary at this point since the orange urine is a known side effect of rifampin and does not require an urgent provider visit. Choice D is incorrect because bladder irritation is not typically associated with isoniazid.

4. A nurse in an outpatient facility is assessing a client who is prescribed furosemide 40 mg 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. Oliguria
• C. Increased urine concentration
• D. Dry mucous membranes

Correct answer: A

Rationale: The correct answer is A: Urine specific gravity of 1.035. A urine specific gravity greater than 1.030 indicates dehydration as the kidneys conserve water in response to dehydration. Choice B, oliguria, refers to decreased urine output, which can be a sign of dehydration but is not specific to it. Choice C, increased urine concentration, is a general term and does not directly indicate dehydration. Choice D, dry mucous membranes, can be a sign of dehydration but is not as specific as a urine specific gravity greater than 1.030.

5. 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.
