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 LPN is caring for a 9-month-old infant. Which of these behaviors exhibited by the child warrants further investigation?

• A. She prefers crawling over walking and makes no attempt to walk.
• B. She seems distressed by new adults.
• C. She does not respond to her own name.
• D. She only babbles "mama"? and "dada."?

Correct answer: C

Rationale: The correct answer is that the child does not respond to her own name. By 9 months, children should be babbling simple words, crawling, and responding to their name. Not responding to one's name can be an early indicator of a potential developmental delay, warranting further investigation. Preferring crawling over walking, being distressed by new adults, and babbling 'mama' and 'dada' are typical behaviors for a 9-month-old and do not necessarily require immediate concern.

3. What is the threshold of dextrose concentrations that can safely be administered through a peripheral IV?

• A. Dextrose concentrations below 20% can be safely administered through a peripheral IV; dextrose concentrations above 20% should not be administered through a peripheral IV.
• B. Dextrose concentrations below 5% can be safely administered through a peripheral IV; dextrose concentrations above 5% should not be administered through a peripheral IV.
• C. Dextrose concentrations below 10% can be safely administered through a peripheral IV; dextrose concentrations above 10% should not be administered through a peripheral IV.
• D. Dextrose concentrations above 5% can be safely administered through a peripheral IV; dextrose concentrations below 5% should not be administered through a peripheral IV.

Correct answer: C

Rationale: Dextrose concentrations below 10% are considered safe for administration through a peripheral IV, as concentrations above this threshold can lead to phlebitis, causing inflammation of the vein. Concentrations above 10% should not be administered through a peripheral IV to prevent vein irritation. Choice A is incorrect because concentrations above 20% are too high for a peripheral IV. Choice B is incorrect as dextrose concentrations below 5% are too low to be effective. Choice D is incorrect because the statement is reversed, suggesting that concentrations above 5% are safe, which is not true.

4. While assessing a client’s skin, the nurse notes the presence of several large red-blue and purple areas on the client’s body that do not blanch when pressure is applied. The nurse documents this finding using which term?

• A. Psoriasis
• B. Anasarca
• C. Petechiae
• D. Ecchymosis

Correct answer: D

Rationale: Ecchymosis refers to a large patch of capillary bleeding into the tissues, commonly known as a bruise. The color of such an area changes from red-blue or purple to green, yellow, and brown before the area disappears. Pressure on the area will not cause it to blanch. Psoriasis is characterized by scaly erythematous patches with silvery scales on top, usually found on specific areas like the scalp, elbows, knees, low back, and anogenital area. Anasarca is bilateral or generalized edema, indicating a central problem like congestive heart failure or kidney failure. Petechiae are tiny purple or red spots resulting from tiny hemorrhages within the dermal and subdermal areas. Therefore, in this case, the correct term to document the described finding is Ecchymosis.

5. Diagnostic genetic counseling, for procedures such as amniocentesis and chorionic villus sampling, allows clients to make all of the following choices except:

• A. terminating the pregnancy.
• B. preparing for the birth of a child with special needs.
• C. accessing support services before the birth.
• D. completing the grieving process before the birth.

Correct answer: D

Rationale: Diagnostic genetic counseling provides clients with important information to make informed decisions regarding their pregnancy. Clients can choose to terminate the pregnancy, prepare for the birth of a child with special needs, and access support services before the birth based on the genetic testing results. However, completing the grieving process before the birth is not a typical choice during genetic counseling. The grieving process, if needed, may extend beyond the prenatal period, especially if the findings are concerning or indicate potential issues. Therefore, completing the grieving process before the birth is the exception among the provided options.
