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. Quality is defined as a combination of all of the following except:

• A. conforming to standards.
• B. performing at the minimally acceptable level.
• C. meeting or exceeding customer requirements.
• D. exceeding customer expectations.

Correct answer: B

Rationale: The correct answer is 'performing at the minimally acceptable level.' Quality is about meeting or exceeding customer requirements and expectations, as well as conforming to standards. The term 'performing at the minimally acceptable level' implies just meeting the minimum requirements, which falls short of the comprehensive definition of quality in terms of customer satisfaction and excellence. Therefore, this choice is the exception when defining quality. Choices A, C, and D align with the definition of quality as they all involve meeting or surpassing certain criteria for customer satisfaction and product excellence, which are essential components of quality management.

4. A client has just returned from surgery where a femoral-popliteal bypass was performed. The nurse has assessed the client and is unable to feel a pulse at either the dorsalis pedis or the posterior tibial sites of the left foot. The foot feels warm, and the color is pink. What action should the nurse perform next to prevent ischemia?

• A. Notify the physician immediately
• B. Obtain a Doppler device to check for pulses, and notify the physician if they are still absent
• C. Wait 30 minutes and recheck the pulses
• D. Document the finding

Correct answer: B

Rationale: The nurse should immediately obtain a Doppler device and recheck the pulses. The dorsalis pedis and posterior tibial pulses can be difficult to assess and might need to be verified with a Doppler device. Since the client just had surgery with a risk of arterial insufficiency, close monitoring is crucial. If pulses are not palpable, it indicates an emergent situation requiring immediate physician notification. Waiting 30 minutes before reassessment could lead to foot ischemia. While documenting findings is essential, it should follow pulse confirmation or necessary interventions to ensure the client's foot viability.

5. The nurse is teaching parents of a newborn about feeding their infant. Which of the following instructions should the nurse include?

• A. Use the defrost setting on microwave ovens to warm bottles.
• B. When refrigerating formula, discard partially used bottles after 24 hours.
• C. When using formula concentrate, mix one part concentrate and two parts water.
• D. If a portion of one bottle is left for the next feeding, discard it.

Correct answer: B

Rationale: The correct answer is to use the defrost setting on microwave ovens to warm bottles. It is crucial to be cautious when heating bottles in a microwave to prevent milk from becoming superheated. The defrost setting is recommended, and the formula's temperature should always be checked before feeding the baby. Choice B, which advises to discard partially used bottles of refrigerated formula after 24 hours, is also correct. This is important to prevent the introduction of pathogens by the baby into the formula. Choice C, recommending mixing one part formula concentrate with two parts water, is essential for ensuring the correct dilution. Choice D, suggesting to discard any remaining portion of a bottle for the next feeding, is incorrect. It is not necessary to discard the remaining portion if it has been refrigerated promptly and used within a safe time frame. Adding fresh formula to a partially used bottle is not recommended, as it can lead to the growth of pathogens that may be transferred to the new formula.
