NCLEX RN Practice Questions Exam Cram

1. Following mitral valve replacement surgery, a client develops PVCs. The healthcare provider orders a bolus of Lidocaine followed by a continuous Lidocaine infusion at a rate of 2 mg/minute. The IV solution contains 2 grams of Lidocaine in 500 mL of D5W. The infusion pump delivers 60 microdrops/mL. What rate would deliver 4 mg of Lidocaine per minute?

Correct answer: A

Rationale: To calculate the rate needed to deliver 4 mg/minute of Lidocaine, first, convert 2 grams to milligrams: 2 grams = 2000 mg. Then, set up a ratio between the total amount of Lidocaine (2000 mg) and the total volume of IV solution (500 mL): 2000 mg / 500 mL = 4 mg / x mL. Solving for x, x = 1 mL. Since the infusion pump delivers 60 microdrops per mL, multiplying by 60 microdrops/mL gives the correct rate of 60 microdrops/minute. This rate ensures the desired 4 mg of Lidocaine is delivered per minute. Choices B, C, and D are incorrect as they do not align with the accurate calculation based on the provided information.

2. A patient is being discharged from the med-surgical unit. The patient has a history of gastritis. The nurse questions the patient on their usual routine at home. Which of these statements would alert the nurse that additional teaching is required?

Correct answer: A

Rationale: The correct answer is, 'I avoid NSAIDs. I only take a daily aspirin for my heart health.' Aspirin is classified as an NSAID and can exacerbate existing stomach problems, such as gastritis. Therefore, patients with gastritis should avoid aspirin just like any other NSAID. Choice B, 'I always avoid eating hot and spicy foods,' is a good practice for a patient with gastritis. Choice C, 'I will continue taking my antacids with or immediately after meals,' indicates understanding of the correct timing for antacid use. Choice D, 'I will only drink coffee once a week, if even that often,' shows a suitable limitation of coffee intake, which is beneficial for patients with gastritis.

3. The nurse is caring for clients in the pediatric unit. A 6-year-old patient is admitted with 2nd and 3rd degree burns on his arms. The nurse should assign the new patient to which of the following roommates?

Correct answer: A

Rationale: The nurse should be concerned about the burn patient's vulnerability to infection due to compromised skin integrity. Sickle cell disease is not a communicable disease, so rooming the burn patient with a 4-year-old with sickle-cell disease would not pose an increased risk of infection transmission. Rooming the burn patient with a 12-year-old with chickenpox would increase the risk of infection for the burn patient. Rooming with a 6-year-old undergoing chemotherapy may expose the burn patient to potential infections. A 7-year-old with a high temperature could potentially have a contagious illness, which could be risky for the burn patient.

4. The nurse is working in a support group for clients with HIV. Which point is most important for the nurse to stress?

Correct answer: B

Rationale: The correct answer is that clients with HIV must take their medications exactly as prescribed. Antiretrovirals need to be taken as directed to prevent the development of drug-resistant strains and maintain treatment effectiveness. Missing doses can compromise the effectiveness of future treatments. Choice A, informing household members, is important for social support but not the most critical aspect of managing the condition. Choice C, abstaining from substance use, is important but not as crucial as medication adherence. Choice D, avoiding large crowds, is not directly related to HIV management as long as the individual's immune system is not significantly compromised.

5. A newborn has been diagnosed with hypothyroidism. In discussing the condition and treatment with the family, the nurse should emphasize:

Correct answer: B

Rationale: The correct answer is administration of thyroid hormone will prevent problems. In newborns diagnosed with hypothyroidism, early identification and continuous treatment with hormone replacement can correct this condition effectively. Choice A is incorrect as it uses outdated and inappropriate language (mentally retarded) and does not reflect modern understanding of conditions. Choice C is incorrect because while some cases of hypothyroidism can be hereditary, it is not always the case. Choice D is incorrect as physical growth and development can be affected by hypothyroidism, but the critical emphasis should be on the importance of administering thyroid hormone to prevent complications and support normal growth and development.
