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: C

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. 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: D

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.

3. What is the therapeutic range for carbamazepine (Tegretol)?

• A. 7-12 mcg/mL
• B. 4-10 mcg/mL
• C. 10-14 mcg/mL
• D. 1-5 mcg/mL

Correct answer: B

Rationale: The therapeutic range for carbamazepine (Tegretol) is 4-10 mcg/mL. This range is established based on the optimal balance between effectiveness and safety. Choices A, C, and D are outside the therapeutic range for carbamazepine, which could lead to suboptimal treatment outcomes or increased risk of toxicity. Choice B (4-10 mcg/mL) is the correct range recommended for therapeutic efficacy while minimizing adverse effects.

4. The LPN is caring for a client newly diagnosed with HIV. Which statement made by the client regarding antiretroviral therapy (ART) would require correction from the nurse?

• A. "If I start ART and use condoms, I'm less likely to transmit HIV to my partner."?
• B. "I can still use ART even though I am Hepatitis C positive."?
• C. "I will need to be on ART indefinitely."?
• D. "I know I will need to come back for blood draws so that I can begin ART when my CD4 count is over 1,000 cells/mm3."?

Correct answer: D

Rationale: The correct answer is the statement, "I know I will need to come back for blood draws so that I can begin ART when my CD4 count is over 1,000 cells/mm3."? This statement would require correction from the nurse because initiating ART when the CD4 count is over 1,000 cells/mm3 is not supported by guidelines. The World Health Organization (WHO) recommends making treatment a priority for those with a CD4 count of ?350 cells/mm3, as early intervention can help delay disease progression. Therefore, waiting for a CD4 count of over 1,000 cells/mm3 is not in line with current recommendations. Choice A is correct, as studies have shown that using condoms along with ART can significantly reduce the risk of HIV transmission to sexual partners. Choice B is also correct because being Hepatitis C positive does not contraindicate the use of ART. Choice C is correct as well, as ART is typically needed indefinitely to maintain viral suppression and manage HIV. Therefore, the only statement that would require correction is Choice D.

5. A 65-year-old female client is experiencing postmenopausal bleeding. Which type of physician should this client be encouraged to see?

• A. a radiologist
• B. a gynecologist
• C. a physiatrist
• D. an oncologist

Correct answer: B

Rationale: A 65-year-old female experiencing postmenopausal bleeding should be encouraged to see a gynecologist. Gynecologists specialize in treating and managing diseases of the female reproductive organs, making them the most appropriate physician for this issue. Postmenopausal bleeding can indicate various gynecological conditions such as endometrial atrophy, endometrial hyperplasia, or endometrial cancer, highlighting the importance of consulting a gynecologist for proper diagnosis and management. Radiologists evaluate X-rays, physiatrists manage rehabilitation teams, and oncologists treat clients with cancer. Therefore, in this case, the symptoms point towards a gynecological problem, emphasizing the necessity of seeking care from a gynecologist.
