Nursing Elites

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. A nurse assisting with data collection notes that the client exhibits rapid, involuntary oscillating movements of the eyeball when looking at the nurse. The nurse documents this finding using which term?

• A. Ptosis
• B. Nystagmus
• C. Scleral icterus
• D. Exophthalmos

Correct answer: B

Rationale: When a nurse observes rapid, involuntary oscillating movements of the eyeball in a client, this is described as nystagmus. Nystagmus appears as a fine oscillating movement, most notable around the iris. It is important to assess for nystagmus when evaluating ocular muscle weakness. Mild nystagmus at extreme lateral gaze is considered normal; nystagmus in any other position is not. Ptosis refers to a drooping of the eyelid, not rapid eye movements. Scleral icterus is the yellowing of the sclera up to the cornea, indicating jaundice, not related to eye movements. Exophthalmos is a noticeable protrusion of the eyeball, typically seen in hyperthyroidism, not associated with rapid oscillating eye movements.

3. A nurse demonstrates the procedure for bathing a newborn to a new mother. The next day, the nurse watches as the mother bathes the infant. The nurse determines that the mother is performing the procedure correctly if the mother performs which action?

• A. Uses a cotton-tipped swab to carefully clean inside the infant's nose
• B. Uncovers only the body part being washed
• C. Washes the diaper area first
• D. Washes the infant's chest first

Correct answer: B

Rationale: When bathing a newborn, it is crucial to follow a specific sequence for thorough cleaning and safety. The correct sequence includes starting with the eyes and face, then moving to the external ear, areas behind the ears, neck, hands, arms, legs, and finally the diaper area. Keeping the infant warm is essential, so only the body part being washed should be uncovered. Using a cotton-tipped swab to clean inside the infant's nose is not recommended due to the risk of injury if the infant moves suddenly. Washing the diaper area first is incorrect as it should be done towards the end of the bath to prevent contamination. Washing the infant's chest first is also incorrect as it deviates from the recommended bathing sequence for a newborn.

4. A client asks the nurse what risk factors increase the chances of getting skin cancer. The risk factors include all except:

• A. light or fair complexion.
• B. exposure to sun for extended periods of time.
• C. certain diet and foods.
• D. history of bad sunburns.

Correct answer: C

Rationale: The correct answer is 'certain diet and foods.' Risk factors that increase the chances of getting skin cancer include having a light or fair complexion, a history of bad sunburns, personal or family history of skin cancer, outdoor activities with sun exposure, exposure to X-rays or radiation, exposure to certain chemicals, repeated trauma or injury resulting in scars, age over 50, male gender, and living in specific geographic locations. These factors can contribute to the development of skin cancer. Avoiding exposure to the sun, using protective clothing and sunscreen, and regular skin inspections are key preventive measures. Choice C, 'certain diet and foods,' is incorrect as diet is not a primary risk factor for skin cancer. Options A, B, and D are all valid risk factors associated with an increased risk of developing skin cancer.

5. A nurse assisting with data collection is preparing to assess the optic nerve. The nurse performs this examination by using which technique?

• A. Assessing visual acuity
• B. Inspecting the eyelids for ptosis
• C. Assessing pupil constriction
• D. Assessing ocular movements

Correct answer: A

Rationale: The correct technique to assess the optic nerve is by testing visual acuity and visual fields through confrontation. Visual acuity involves assessing the clarity of vision, which directly correlates with the function of the optic nerve. Inspecting the eyelids for ptosis is unrelated to optic nerve assessment. Assessing pupil constriction is more related to the assessment of cranial nerves controlling eye movements, particularly the oculomotor nerve. Assessing ocular movements is related to testing the abducens, oculomotor, and trochlear nerves, not specifically the optic nerve.
