Nursing Elites

1. 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.

2. A male client is learning about testicular self-examination (TSE) from a nurse. Which statement should the nurse make to the client?

• A. 'A good time to examine the testicles is during or after you take a shower.'
• B. 'If you notice an enlarged testicle or a lump, you need to notify the physician.'
• C. 'The testicle is round and smooth. It feels firm and without lumps.'
• D. 'Perform a testicular exam monthly to detect early signs of testicular cancer.'

Correct answer: B

Rationale: The correct statement for the nurse to make to the client is 'If you notice an enlarged testicle or a lump, you need to notify the physician.' During a shower or bath is the best time to examine the testes because warm temperatures make the testes hang lower in the scrotum. The testes should feel round and smooth, without lumps. Self-examination should be performed monthly to detect any abnormalities early. The physician needs to be notified immediately if any abnormal findings are noticed. Choice A is incorrect because the best time for TSE is during or after a warm shower or bath, not just before. Choice C is incorrect as the testicle should feel round, smooth, and without lumps, not egg-shaped and lumpy. Choice D is incorrect as monthly self-examinations are recommended, not every 2 months.

3. Which of the following solutions is routinely used to flush an IV device before and after the administration of blood to a client?

• A. 0.9% sodium chloride
• B. 5% dextrose in water solution
• C. Sterile water
• D. Heparin sodium

Correct answer: A

Rationale: The correct answer is 0.9% sodium chloride. Normal saline is 0.9% sodium chloride, which has the same osmolarity as blood and does not cause cell lysis. Choices 2 and 3, 5% dextrose in water solution and sterile water, are hypotonic solutions that can lead to cell lysis. Choice 4, heparin sodium, is an anticoagulant and is not used for flushing IV devices before and after blood administration.

4. 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.

5. A nurse assisting with data collection of the peripheral vascular system performs the Allen test. The nurse understands that this test is used to determine the patency of which blood vessel(s)?

• A. Capillaries
• B. Pedal pulses
• C. Femoral arteries
• D. Radial and ulnar arteries

Correct answer: D

Rationale: The nurse performs the Allen test to determine the patency of the radial and ulnar arteries. During the test, the nurse applies pressure over the client's ulnar and radial arteries simultaneously. The client is then asked to open and close the hand repeatedly, causing the hand to blanch. Subsequently, the nurse releases pressure from the ulnar artery while compressing the radial artery and checks the color of the extremity distal to the pressure point. If pinkness fails to return within 6 seconds, it indicates that the ulnar artery is insufficient, suggesting that the radial artery should not be used for obtaining a blood specimen. Choice A (Capillaries) is incorrect as the Allen test assesses the patency of larger arteries, not capillaries. Choice B (Pedal pulses) is incorrect as the Allen test specifically evaluates the radial and ulnar arteries, not the pedal pulses in the foot. Choice C (Femoral arteries) is incorrect as the Allen test focuses on the radial and ulnar arteries in the hand, not the femoral arteries in the leg.
