NCLEX PN 2023 Quizlet

1. What is pica?

Correct answer: D

Rationale: Pica is a disorder characterized by the ingestion of nonfood substances, which can lead to a clinical iron deficiency. It may be the first sign of an underlying issue. Individuals with pica consume a variety of nonfood items such as ice, clay, dirt, or paste. Choice A, dependency on alcohol, is incorrect as it is not related to pica. Choice B, increased iron in the diet, is incorrect because pica involves ingesting nonfood items rather than having an increased intake of iron. Choice C, the sickle cell trait, is unrelated to pica and is therefore incorrect.

2. Which physiologic mechanism best describes the function of the sodium-potassium pump?

Correct answer: A

Rationale: Active transport is the correct answer as it accurately describes the process involved in the sodium-potassium pump. The pump utilizes energy to move ions against their concentration gradient, maintaining cellular concentrations. Diffusion (choice B) is a passive process where substances move from an area of higher concentration to lower concentration. Filtration (choice C) involves the movement of solutes based on pressure gradients. Osmosis (choice D) is the movement of water across a semipermeable membrane.

3. Which reported symptom would indicate a client with Addison's disease has received too much fludrocortisone (Florinef) replacement?

Correct answer: B

Rationale: Fludrocortisone (Florinef) replacement in Addison's disease involves mimicking aldosterone to retain sodium and water. This retention can lead to weight gain due to increased fluid retention. Rapid weight gain, such as 6 pounds in one week, is a concerning sign of excessive fluid retention, indicating a potential overdose of fludrocortisone. Choices A, C, and D are incorrect because oily skin and hair, loss of muscle mass, and increased blood glucose levels are not specific symptoms of excessive fludrocortisone replacement in Addison's disease.

4. Which of the following medications is a serotonin antagonist that might be used to relieve nausea and vomiting?

Correct answer: B

Rationale: Zofran is a serotonin antagonist commonly used to relieve nausea and vomiting by blocking serotonin receptors. Metoclopramide (Reglan) acts on dopamine receptors, hydroxyzine (Vistaril) is an antihistamine, and prochlorperazine (Compazine) is a dopamine antagonist. While these medications can also be used for nausea and vomiting, they do not primarily function as serotonin antagonists like ondansetron.

5. While performing wound care to a donor skin graft site, the nurse notes some scabbing at the edges and a black collection of blood. What is the nurse's next action?

Correct answer: C

Rationale: When the nurse notes scabbing at the edges and a black collection of blood, it indicates the presence of debris that needs to be addressed. Leaving the scabbed area alone and applying extra ointment may not address the underlying issue and could lead to complications. Notifying the physician is important in some cases, but immediate action is required to prevent infection in this situation. Gently removing the debris and re-dressing the wound is the correct course of action to promote healing and prevent complications.
