NCLEX RN Practice Questions Exam Cram

1. The nurse is caring for a 2-year-old who is being treated with chelation therapy, calcium disodium edetate, for lead poisoning. The nurse should be alert for which of the following side effects?

A. Neurotoxicity
B. Hepatomegaly
C. Nephrotoxicity
D. Ototoxicity

Correct answer: C

Rationale: The correct answer is nephrotoxicity. Calcium disodium edetate, used in chelation therapy for lead poisoning, can lead to kidney toxicity. This is an important side effect to monitor in patients undergoing this treatment. Choices A, B, and D are incorrect. Neurotoxicity, hepatomegaly, and ototoxicity are not typically associated with calcium disodium edetate therapy for lead poisoning.

2. Which of the following is TRUE about shock?

A. A patient with severe shock does not always have an abnormally low blood pressure.
B. Confusion and deteriorating mentation are indicative of hypotensive shock.
C. Patients with compensated shock may not be able to maintain a normal blood pressure.
D. A normal blood pressure does not imply that the patient is stable.

Correct answer: B

Rationale: Confusion and deteriorating mentation are indeed indicative of hypotensive shock. It is important to note that a patient with hypotensive shock will likely exhibit deteriorating mental status. Choice A is incorrect because a patient in severe shock may not always have an abnormally low blood pressure, making it an unreliable indicator of shock severity. Choice C is incorrect because patients with compensated shock may present with normal blood pressure but still have inadequate tissue perfusion. Choice D is incorrect because a normal blood pressure does not guarantee the patient's stability, especially in cases of shock where tissue perfusion may be compromised despite normal blood pressure readings.

3. The healthcare professional calculates the IV flow rate for a patient receiving an antibiotic. The patient is to receive 100mL of the antibiotic over 30 minutes. The IV infusion set has a drop factor of 10 drops per milliliter. How many drops per minute should the healthcare professional set the IV to deliver?

A. 11
B. 19
C. 26
D. 33

Correct answer: D

Rationale: To determine the drops per minute for the IV flow rate, you can use the formula: Drops Per Minute = (Milliliters to be infused x Drop Factor) / Time in Minutes. Substituting the given values, you get 100 mL x 10 drops/mL / 30 minutes = 33 drops per minute. Therefore, the correct answer is 33, as the healthcare professional should set the IV to deliver 33 drops per minute to infuse the antibiotic correctly. Choices A, B, and C are incorrect as they do not match the calculated drops per minute based on the provided values.

4. The physician has decided to perform a thoracentesis based on Mr. R's assessment. Which of the following actions from the nurse is most appropriate?

A. Instruct the client not to talk during the procedure
B. Assist the client to sit upright or slightly lean forward
C. Insert a 20-gauge needle just above the 4th intercostal space
D. Connect the needle to suction to remove fluid that has collected in the pleural space

Correct answer: A

Rationale: The correct answer is to instruct the client not to talk during the procedure. This is important to prevent air from being drawn into the pleural space during the thoracentesis. Choice B is incorrect because the client should be sitting upright or slightly leaning forward during the procedure to facilitate access to the pleural space. Choice C is incorrect as the nurse should not perform the thoracentesis procedure, which involves inserting a needle into the pleural space - this is the physician's responsibility. Choice D is incorrect as connecting the needle to suction to remove fluid is not the appropriate procedure for a thoracentesis. Thoracentesis is typically done to remove fluid or air for diagnostic or therapeutic purposes, not to connect to suction to remove fluid that has collected in the pleural space.

5. An infant weighed 7 pounds 8 ounces at birth. If growth occurs at a normal rate, what would be the expected weight at 6 months of age?

A. Double the birth weight
B. Triple the birth weight
C. Gain 6 ounces each week
D. Add 2 pounds each month

Correct answer: A

Rationale: Infants typically double their birth weight by 6 months of age as part of normal growth and development. This doubling of weight is a common milestone used by healthcare providers to assess a baby's growth progress. Tripling the birth weight or adding 2 pounds each month would result in excessive weight gain, which is not typical or healthy for an infant. Similarly, gaining 6 ounces each week would also lead to rapid and abnormal weight gain, making it an incorrect choice.
