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 taking care of a client who is on Phenelzine (Nardil) for depression. Which meal would the nurse encourage the client to avoid?

• A. steak and potatoes
• B. prosciutto and cheese plate
• C. orange juice and toast
• D. carbonated water, shrimp and rice

Correct answer: B

Rationale: The correct answer is 'prosciutto and cheese plate.' Phenelzine (Nardil) is an MAOI (Monoamine Oxidase Inhibitor), and clients on these drugs should avoid foods high in tyramine due to the risk of dangerous elevations in blood pressure. Prosciutto and aged cheeses are examples of foods rich in tyramine, so they should be avoided. Choices A, C, and D do not contain high levels of tyramine and are considered safe to consume while on Phenelzine.

3. A healthcare professional reviewing a client's record notes documentation that the client has melena. How does the healthcare professional detect the presence of melena?

• A. By checking the client's urine for blood
• B. By checking the client's stool for blood
• C. By checking the client's urine for a decrease in output
• D. By checking the client's bowel movements for diarrhea

Correct answer: B

Rationale: Melena' is the term used to describe abnormal black tarry stool that has a distinctive odor and contains digested blood. It usually results from bleeding in the upper gastrointestinal tract and is often a sign of peptic ulcer disease or small bowel disease. The presence of melena is detected by checking the client's stool for blood. Blood in the client's urine, decreased urine output, and diarrhea are not associated with the assessment for melena.

4. A hepatitis B screen is performed on a pregnant client, and the results indicate the presence of antigens in the client's blood. On the basis of this finding, the nurse makes which determination?

• A. Hepatitis immune globulin and vaccine will be administered to the newborn infant soon after birth
• B. The results are negative.
• C. The results indicate that the mother does not have hepatitis B
• D. The client needs to receive the hepatitis B series of vaccines.

Correct answer: A

Rationale: A hepatitis B screen is performed to identify antigens in maternal blood. If antigens are present, it indicates that the mother is a carrier, and the newborn will need to receive hepatitis immune globulin and vaccine soon after birth to prevent transmission. Therefore, choice A is correct. Choices B and C are incorrect because the presence of antigens indicates a positive result, not a negative one or the absence of hepatitis B in the mother. Choice D is incorrect as it suggests the client needs to receive the hepatitis B series of vaccines, which is not the immediate action required when antigens are found in the maternal blood.

5. The nurse is assessing an 18-month-old. Which of these statements made by the parent or caregiver would require follow-up?

• A. I'm worried that my child is not using two-word phrases yet.
• B. My child has recently taken a few steps but does not seem stable when standing.
• C. My child seems to have developed separation anxiety when I leave.
• D. I'm letting my child use a spoon to eat.

Correct answer: B

Rationale: The correct answer is 'My child has recently taken a few steps but does not seem stable when standing.' By 18 months of age, children should have taken their first steps and stand well. If a child hasn't made progress by this age, a physical therapy evaluation may be necessary. It is normal for an 18-month-old to start using a spoon to eat. However, the use of two-word phrases is not typically expected until 2 years of age. Separation anxiety is a common developmental phase that typically occurs between 6 and 18 months, so it does not require immediate follow-up. Therefore, the statement about the child not being stable when standing raises a red flag and necessitates further evaluation.
