1. When performing an eye examination, which area can a healthcare provider best visualize using an ophthalmoscope?

• A. Iris
• B. Cornea
• C. Optic disc
• D. Conjunctiva

Correct answer: Optic disc

Rationale: An ophthalmoscope is a tool used to visualize the internal structures of the eye during an examination. The optic disc, located on the internal surface of the retina, can be best visualized using an ophthalmoscope. The iris, cornea, and conjunctiva are superficial structures that can be examined without the need for an ophthalmoscope. Therefore, the correct answer is the optic disc. Choices A, B, and D are incorrect because they are external structures that can be examined directly without the use of an ophthalmoscope.

2. A paraplegic client is in the hospital to be treated for an electrolyte imbalance. Which level of care is the client currently receiving?

• A. primary prevention
• B. secondary prevention
• C. tertiary prevention
• D. health promotion

Correct answer: B

Rationale: The correct answer is B: secondary prevention. The client is currently receiving secondary prevention care. Secondary prevention focuses on early detection of disease, prompt intervention, and health maintenance for clients experiencing health problems. In this case, the electrolyte imbalance is a health problem that requires treatment to prevent further complications. Choices A, C, and D are incorrect because primary prevention is focused on health promotion and specific protections against illness before it occurs, tertiary prevention is aimed at helping rehabilitate clients after the illness is diagnosed and treated, and health promotion is a broader concept that includes activities aimed at improving overall health and well-being rather than targeting a specific health problem like an electrolyte imbalance.

3. The parents of a 2-year-old child ask the nurse how they can teach their child to stop taking toys away from other children. Which of the following statements by the nurse offers the parents the best explanation of their child’s behavior?

• A. “Your child is egocentric. Egocentricity is normal for 2-year-old children. He believes other children want him to have their toys.”
• B. “Your child is showing negativity. He doesn’t want other children to have the toys he wants.”
• C. “Your child is demonstrating magical thinking. He believes he can make the other children want him to play with their toys.”
• D. “Your child is engaging in domestic imitation. He is doing what he has seen other children do.”

Correct answer: “Your child is egocentric. Egocentricity is normal for 2-year-old children. He believes other children want him to have their toys.”

Rationale: Two-year-old children are very egocentric, believing everything revolves around them. They think other children want them to have their toys, which explains why they may take toys from others. This behavior is typical for children at this age as they lack the ability to see things from another's perspective. Option B is incorrect because negativity in children this age is more related to refusal of requests rather than taking toys. Magical thinking, as described in option C, is usually seen in preschool-age children and involves unrealistic beliefs. Option D is incorrect as domestic imitation refers to imitating adult household tasks, not other children's behavior.

4. The LPN is admitting a client to the unit, and the client has rapidly blinking eyes, a stuck-out tongue, and a distorted posture. Which of these medications is the client most likely taking?

• A. Clozapine
• B. Fluoxetine
• C. Ondansetron
• D. Haloperidol

Correct answer: Haloperidol

Rationale: The correct answer is Haloperidol. Haloperidol is a first-generation antipsychotic that blocks dopamine receptors and is most likely to cause extrapyramidal symptoms (EPS), such as tardive dyskinesia. Symptoms of tardive dyskinesia include rapid blinking, mouth movements, sticking out the tongue, rapid body movements, and a distorted posture. Haloperidol is associated with a higher risk of EPS compared to other antipsychotic medications like Clozapine. Clozapine is known for having a lower risk of causing EPS. Fluoxetine is a selective serotonin reuptake inhibitor used for depression and anxiety, not typically associated with these movement disorder symptoms. Ondansetron is an antiemetic used to prevent nausea and vomiting, not linked to these extrapyramidal symptoms.

5. The LPN participates in a home visit for a client with Type 2 Diabetes who has been taking Metformin for 3 years. The client states that for the past 3 months, they have been trying a vegan diet and experiencing fatigue, confusion, and mood changes. What is a likely cause of the new symptoms?

• A. vitamin B12 deficiency
• B. chronic hypoglycemia
• C. vitamin D deficiency
• D. increased tolerance to Metformin

Correct answer: vitamin B12 deficiency

Rationale: The correct answer is vitamin B12 deficiency. Long-term use of Metformin can lead to vitamin B12 deficiency, and a vegan diet is low in vitamin B12. Symptoms of vitamin B12 deficiency include anemia, fatigue, confusion, and mood changes. Chronic hypoglycemia is unlikely in a client with Type 2 Diabetes who has been taking Metformin as it typically causes hyperglycemia. Vitamin D deficiency usually presents with symptoms related to bones and muscles, not confusion and mood changes. Increased tolerance to Metformin does not explain the client's new symptoms, which are more indicative of a nutritional deficiency like vitamin B12.
