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 nurse is preparing to administer iron dextran IV to a client. Which of the following actions should the nurse plan to take?

• A. Administer a small test dose before giving the full dose
• B. Infuse the medication over 30 seconds
• C. Monitor client closely for hypertension
• D. Administer cyanocobalamin as an antidote if toxicity occurs

Correct answer: A

Rationale: The correct action the nurse should plan to take when preparing to administer iron dextran IV is to administer a small test dose before giving the full dose. This is done to assess for any allergic reactions that the client may have to the medication. Choice B is incorrect because iron dextran should be infused slowly over a longer period, typically over 1-2 hours to reduce the risk of adverse reactions. Choice C is incorrect because iron dextran administration is more commonly associated with hypotension rather than hypertension. Choice D is incorrect because cyanocobalamin is not used as an antidote for iron dextran toxicity; instead, treatment for iron toxicity may involve supportive care, chelation therapy, or in severe cases, iron antidotes like deferoxamine.

3. 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.

4. A nurse is providing teaching to a client who has a new prescription for hydrochlorothiazide 50 mg PO daily to treat hypertension. Which of the following instructions should the nurse include in the teaching?

• A. Take hydrochlorothiazide as needed for edema.
• B. Check your weight once weekly.
• C. Take the hydrochlorothiazide on an empty stomach.
• D. Take the hydrochlorothiazide in the morning.

Correct answer: D

Rationale: The correct answer is to take hydrochlorothiazide in the morning. This medication is usually advised to be taken in the morning to prevent nocturia, which is excessive urination at night. Option A is incorrect because hydrochlorothiazide should be taken daily as prescribed, not as needed for edema. Option B is incorrect as monitoring weight weekly may not be specifically related to hydrochlorothiazide therapy. Option C is incorrect as hydrochlorothiazide does not need to be taken on an empty stomach.

5. 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.
