NCLEX RN Practice Questions Quizlet

1. A client must use a non-rebreathing oxygen mask. Which of the following statements is true regarding this type of mask?

A. A non-rebreather can provide an FiO2 of 40%.
B. A client should breathe through his or her mouth when using a non-rebreather.
C. A non-rebreather offers a reservoir from which the client inhales.
D. The mask of a non-rebreather should be changed every 3 hours.

Correct answer: A

Rationale: A non-rebreather mask is used for supplemental oxygen delivery for clients experiencing breathing difficulties. The non-rebreather mask includes a one-way valve that allows exhaled air to escape, preventing the rebreathing of carbon dioxide. The client inhales oxygenated air from a reservoir bag attached to the mask, providing high-concentration oxygen therapy. A non-rebreather mask can deliver FiO2 levels of up to 90%, making it an effective intervention for clients requiring high oxygen concentrations. Therefore, the statement that 'A non-rebreather can provide an FiO2 of 40%' is correct. Choices B, C, and D are incorrect because clients should breathe through their nose and mouth, the mask offers a reservoir for inhaling oxygen, and the mask should be assessed and potentially replaced if soiled or damaged, not routinely changed every 3 hours.

2. Who typically owns a patient's medical record?

A. The patient
B. The physician
C. The Legal Counsel of the Office
D. No one owns a medical record

Correct answer: B

Rationale: The correct answer is 'The physician.' Physicians typically own their patients' medical records as they are the ones responsible for creating, updating, and maintaining these records. However, it is essential to note that patients have the legal right to access and obtain copies of their medical records. Choice A ('The patient') is incorrect as patients do not own their medical records, but they do have rights regarding access to them. Choice C ('The Legal Counsel of the Office') is incorrect as legal counsel typically do not own or have ownership rights over medical records. Choice D ('No one owns a medical record') is incorrect as medical records are owned by healthcare providers who create and maintain them, such as physicians.

3. Mrs. M has had diabetes for seven years. She has worked hard to control her blood glucose levels and watch her dietary intake. Her physician orders a hemoglobin A1C test. Which of the following best describes the action of this test?

A. The test determines if the client is anemic and needs iron supplements
B. The test determines if there is excess glucose building up in the urine
C. The test determines the amount of hemoglobin reaching the liver to support gluconeogenesis
D. The test determines the amount of hemoglobin that is coated with glucose

Correct answer: D

Rationale: A hemoglobin A1C test, also known as a glycated hemoglobin test, determines the amount of hemoglobin that is coated with glucose. Excess glucose in the bloodstream may cause it to attach to hemoglobin on red blood cells. Because the life of these cells is between 2 and 3 months, the hemoglobin A1C is an accurate measurement of a client's glucose during that time. Choices A, B, and C are incorrect. Choice A relates to anemia and iron supplements, which are not assessed by a hemoglobin A1C test. Choice B mentions excess glucose in the urine, which is typically assessed through a urine glucose test, not the hemoglobin A1C test. Choice C is incorrect as the test is not related to the amount of hemoglobin reaching the liver to support gluconeogenesis; instead, it specifically measures the amount of hemoglobin that is glycated or coated with glucose.

4. A client needs to give informed consent for electroconvulsive therapy treatments. Which of the following actions should the nurse take?

A. Explain the adverse effects the client might experience from the treatment
B. Verify the client gave consent voluntarily for the treatment
C. Describe the benefits of the treatment to the client
D. Outline possible alternatives to the treatment for the client

Correct answer: B

Rationale: When obtaining informed consent for a procedure like electroconvulsive therapy, the nurse's primary responsibility is to ensure that the client has given consent voluntarily and is capable of making such a decision. While it is essential to provide information on the treatment's benefits, risks, and alternatives, the priority is to verify the client's voluntary consent. Explaining the adverse effects and describing the benefits are important steps in the informed consent process, but the critical step is to confirm the client's voluntary agreement. Outlining possible alternatives to the treatment is also important but comes after ensuring the client's voluntary consent.

5. Which of the following is an example of low health literacy skills?

A. A nurse is unable to explain the dose, indications, side effects, and structural formula of carbamazepine
B. A client cannot read an admission form to sign it
C. A nurse cannot calculate the correct IV rate for Ringer's lactate
D. A nurse is unable to explain the dose, indications, side effects, and structural formula of carbamazepine

Correct answer: B

Rationale: Low health literacy skills are exemplified by an individual's inability to comprehend health-related information. In this scenario, a client's inability to read an admission form to sign it indicates low health literacy. This lack of understanding can hinder their ability to make informed decisions about their healthcare. The other choices involve healthcare professionals and their knowledge or skills, not the health literacy of individuals seeking care.
