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. A client, age 28, is 8 1/2 months pregnant. She is most likely to display which normal skin-color variation?

• A. vitiligo
• B. erythema
• C. cyanosis
• D. chloasma

Correct answer: D

Rationale: Chloasma, also known as the mask of pregnancy, is described as tan-to-brown patches on the face. This hyperpigmentation results from hormonal changes during pregnancy. Vitiligo is characterized by depigmented patches, erythema is redness of the skin due to increased blood flow, and cyanosis is a bluish discoloration due to poor circulation or lack of oxygen, none of which are typical skin-color variations during pregnancy. Therefore, in a pregnant client, the most likely normal skin-color variation to be displayed is chloasma.

3. The LPN is taking care of a 176-pound client who has recently been diagnosed with diabetes. The primary healthcare provider has written an order for Lantus� (insulin glargine injection) 100 units/mL, using weight-based dosing of 0.2 units/kg per day. The LPN should prepare ____ units for administration.

• A. 12
• B. 35
• C. 16
• D. 9

Correct answer: B

Rationale: To calculate the correct dosage, first convert the client's weight from pounds to kilograms. As 1 kg = 2.2 pounds, 176 pounds � 2.2 = 80 kg. The client should receive 0.2 units for every kilogram, which equals 16 units. Therefore, the total amount to prepare is 16 units x 100 units/mL = 1600 units. Considering the medication concentration of 100 units/mL, 1600 units � 100 units/mL = 16 mL. However, since the question asks for the number of units, the final answer is 16 units x 2 injections = 32 units. Therefore, the LPN should prepare 32 units for administration.

4. Quality is defined as a combination of all of the following except:

• A. conforming to standards.
• B. performing at the minimally acceptable level.
• C. meeting or exceeding customer requirements.
• D. exceeding customer expectations.

Correct answer: B

Rationale: The correct answer is 'performing at the minimally acceptable level.' Quality is about meeting or exceeding customer requirements and expectations, as well as conforming to standards. The term 'performing at the minimally acceptable level' implies just meeting the minimum requirements, which falls short of the comprehensive definition of quality in terms of customer satisfaction and excellence. Therefore, this choice is the exception when defining quality. Choices A, C, and D align with the definition of quality as they all involve meeting or surpassing certain criteria for customer satisfaction and product excellence, which are essential components of quality management.

5. When removing hard contact lenses from an unresponsive client, what should the nurse do?

• A. Gently irrigate the eye with an irrigating solution from the inner canthus outward.
• B. Grasp the lens with a gentle pinching motion.
• C. Don sterile gloves before attempting the procedure.
• D. Ensure that the lens is centered on the cornea before gently manipulating the lids to release the lens.

Correct answer: D

Rationale: When removing hard contact lenses, it is crucial to ensure that the lens is correctly positioned on the cornea before removal. Directly grasping the lens can potentially scratch the cornea, so it is essential to gently manipulate the lids to release the lens safely. Gently irrigating the eye is unnecessary and could be harmful, especially without the client's cooperation. Wearing sterile gloves is also unnecessary for this specific procedure. Therefore, the correct approach is to ensure the proper positioning of the lens and then gently manipulate the lids to release it. Options A and C are incorrect because irrigating the eye and wearing sterile gloves are not necessary for contact lens removal. Option B is incorrect as directly grasping the lens can be harmful to the cornea.
