Nursing Elites

1. A nurse is preparing to screen a client's vision with the use of a Snellen chart. The nurse uses which technique?

• A. Tests the right eye, then tests the left eye, and finally tests both eyes together
• B. Assesses both eyes together, then assesses the right and left eyes separately
• C. Asks the client to stand 40 feet from the chart and read the largest line on the chart
• D. Asks the client to stand 40 feet from the chart and read the line that can be read 200 feet away by someone with unimpaired vision

Correct answer: A

Rationale: To test visual acuity with the use of a Snellen chart, the nurse places the chart in a well-lit spot at the client's eye level, with the client positioned exactly 20 feet from the chart. The client shields one eye at a time with an opaque card during the test. After testing each eye separately, both eyes are assessed together. The client is asked to read the smallest line of letters visible and encouraged to read the next smallest line as well. Therefore, option A is correct as it describes the correct technique of testing one eye at a time before assessing both eyes together. Option B is incorrect as it assesses both eyes together first, which is not the standard procedure. Options C and D are incorrect as they suggest standing 40 feet from the chart, which contradicts the standard distance of 20 feet for a Snellen chart test.

2. The nurse is caring for a female client who has recently been diagnosed with cancer and will soon begin chemotherapy. Which of these statements would require additional follow-up and education?

• A. I will be most susceptible to an infection between 7 and 12 days after chemotherapy.
• B. I should try to get my annual teeth cleaning in before beginning chemotherapy.
• C. I should wait until all my hair falls out to purchase a wig.
• D. I should try to drink 8-10 glasses of water a day.

Correct answer: C

Rationale: This client is at risk for altered body image due to chemotherapy-induced hair loss. A wig can assist in coping with this change. It is advisable for the client to shop for a wig before hair loss occurs to better match color and style. Waiting until all hair falls out may lead to stress and limited options in finding a suitable wig. Choices A, B, and D are accurate. Understanding the timing of susceptibility to infection, maintaining oral health before chemotherapy, and staying hydrated are important aspects of care during chemotherapy. Therefore, the statement 'I should wait until all my hair falls out to purchase a wig' requires additional follow-up and education.

3. A nurse is preparing to assess a client for the presence of the Tinel sign. Which action does the nurse take to elicit this sign?

• A. Testing for the strength of each muscle joint
• B. Percussing at the location of the median nerve
• C. Checking for repetitive movements in the joints
• D. Asking the client to flex the wrist 90 degrees while holding the hands back to back

Correct answer: B

Rationale: The Tinel sign is elicited by percussing at the location of the median nerve at the wrist. In carpal tunnel syndrome, this test can produce burning and tingling along the nerve's distribution. Choices A, C, and D are incorrect. Testing for the strength of each muscle joint and checking for repetitive movements in the joints involve different assessments unrelated to the Tinel sign. Asking the client to flex the wrist 90 degrees while holding the hands back to back is associated with the Phalen test, which is another evaluation for carpal tunnel syndrome.

4. 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.

5. The nurse is caring for a client who has dysphagia related to a stroke. The nurse works with the client to explain what food and beverages might minimize aspiration. What is this an example of?

• A. Health promotion
• B. Secondary prevention
• C. Tertiary prevention
• D. Primary prevention

Correct answer: B

Rationale: The nurse working with the client to explain what food and beverages might minimize aspiration is an example of secondary prevention. Secondary prevention involves early detection and intervention to prevent complications or worsening of a condition. In this case, the nurse is helping to prevent aspiration pneumonia by providing education and guidance on safe eating and drinking practices after the client has already experienced dysphagia due to a stroke. Choice A, health promotion, focuses on empowering individuals to adopt healthy behaviors to improve overall well-being and prevent illness. It is more about promoting general health rather than specific interventions related to a particular condition like dysphagia. Choice C, tertiary prevention, involves managing and rehabilitating a condition to prevent further complications or disabilities. In this scenario, the nurse is not yet addressing complications but rather actively preventing them. Choice D, primary prevention, aims to prevent the onset of a disease or condition before it occurs. The client in this case already has dysphagia, so the focus is on preventing further complications, making it a secondary prevention intervention.
