Nursing Elites

1. A nurse reviewing a client's record notes that the result of the client's latest Snellen chart vision test was 20/80. The nurse interprets the client's results in which way?

• A. The client is legally blind.
• B. The client has normal vision.
• C. The client can read at a distance of 20 feet what a client with normal vision can read at 80 feet.
• D. The client can read at a distance of 80 feet what a client with normal vision can read at 20 feet.

Correct answer: D

Rationale: When interpreting visual acuity testing results using the Snellen chart, the recorded numeric fraction represents the distance the client is standing from the chart and the distance a normal eye could read that particular line. A reading of 20/80 means that the client can read at 20 feet what a client with normal vision can read at 80 feet. This indicates visual impairment but does not meet the criteria for legal blindness, which is defined as best-corrected vision in the better eye of 20/200 or worse. Normal visual acuity is 20/20. Therefore, the correct interpretation is that the client can read at a distance of 80 feet what a client with normal vision can read at 20 feet. Choice A is incorrect because 20/80 does not meet the criteria for legal blindness. Choice B is incorrect as the client's vision is impaired. Choice C is incorrect because it reverses the interpretation of the fraction.

2. 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 water and one part concentrate.
• D. When using powdered formula, mix two parts water and one part powder.

Correct answer: A

Rationale: The correct answer is to use the defrost setting on microwave ovens to warm bottles. It is essential for parents to be cautious when warming bottles in a microwave oven to prevent superheating of the milk. Choosing the defrost setting and checking the formula temperature before giving it to the baby helps avoid burns. Discarding partially used bottles after 24 hours when refrigerating formula is crucial as it reduces the risk of harmful bacterial growth. Mixing formula concentrate with water in a 1:1 ratio of one part concentrate to one part water ensures proper dilution of the formula. On the other hand, powdered formula should be mixed following the package instructions, typically using two parts water to one part powder. This accurate mixing ratio provides the necessary balance of nutrients for the baby. Adding fresh formula to partially used bottles can introduce pathogens that may harm the infant, underscoring the importance of discarding partially used bottles and preparing formula correctly. Therefore, options B, C, and D are incorrect as they do not address the safe and proper ways to feed a newborn effectively.

3. While assessing for costovertebral angle tenderness, a nurse percusses the area, and the client complains of sharp pain. The nurse interprets this finding as most indicative of which disorder?

• A. Liver enlargement
• B. Ovarian infection
• C. Spleen enlargement
• D. Kidney inflammation

Correct answer: D

Rationale: When assessing for costovertebral angle tenderness, sharp pain on percussion of the area indicates inflammation of the kidney or paranephric area. The correct technique involves placing one hand over the 12th rib, at the costovertebral angle, and thumping that hand with the ulnar edge of the other fist. The client normally feels a thud and should not experience pain. Ovarian infection, liver enlargement, or spleen enlargement are not associated with the costovertebral angle tenderness. Therefore, the correct answer is kidney inflammation.

4. A healthcare professional is using an otoscope to inspect the ears of an adult client. Which action does the professional take before inserting the otoscope?

• A. Pulling the pinna up and back
• B. Pulling the pinna down and forward
• C. Tipping the client's head down and toward the examiner
• D. Tipping the client's head down and away from the examiner

Correct answer: A

Rationale: In an adult client, the healthcare professional should pull the pinna up and back before inserting the otoscope. This action helps straighten the S shape of the ear canal, making it easier to insert the otoscope directly and comfortably. Tipping the client's head down and toward or away from the examiner is not the correct action when using an otoscope in an adult. Pulling the pinna down and forward is typically done when examining an infant or a child younger than 3 years old to straighten their ear canal for better visualization.

5. When examining the abdomen, a nurse auscultates before palpating and percussing the abdomen. The nurse performs the assessment in this manner for which reason?

• A. It is less painful for the client.
• B. Palpation and percussion can increase peristalsis.
• C. It identifies any potential areas of abdominal tenderness.
• D. It gives the client more time to become comfortable with the examiner.

Correct answer: B

Rationale: When performing an abdominal assessment, the nurse auscultates the abdomen after inspection. Auscultation is done before palpation and percussion because these assessment techniques can increase peristalsis, which would yield a false interpretation of bowel sounds. This sequence helps prevent false interpretations of bowel sounds due to increased peristalsis caused by palpation and percussion. Options A, C, and D provide incorrect reasons for auscultating the abdomen before palpating and percussing it.
