1. What is the primary nutritional deficiency of concern for a strict vegetarian?

• A. vitamin C
• B. vitamin B12
• C. vitamin E
• D. magnesium

Correct answer: B

Rationale: Vitamin B12 is the primary nutritional deficiency of concern for a strict vegetarian. While all mentioned vitamins are essential for overall health, vitamin B12 is particularly important for vegetarians as it is mainly found in animal products. A strict vegetarian diet may lack sufficient vitamin B12 intake, leading to potential health issues like anemia and neurological problems. Vitamin C deficiency is more commonly associated with scurvy, which is preventable with a diet rich in fruits and vegetables. Vitamin E deficiency is rare and usually only seen in specific medical conditions. Magnesium deficiency is not typically a primary concern for strict vegetarians as magnesium can be obtained from a variety of plant-based sources.

2. The client should include all of the following in teaching an obese client about nutritional needs and weight loss except:

• A. knowledge of food and food products
• B. development of a positive mental attitude
• C. adequate exercise
• D. starting a fast weight-loss diet

Correct answer: D

Rationale: When educating an obese client about nutritional needs and weight loss, it is crucial to emphasize a holistic approach that involves understanding food and food products, fostering a positive mental attitude, and incorporating adequate exercise. Initiating a fast weight-loss diet is not advisable due to potential health risks and lack of long-term sustainability. Therefore, this option stands out as the exception and should not be part of the client's learning. Choices A, B, and C are essential components of a healthy weight-loss plan and should be included in the client's education.

3. What is most likely to impact the body image of an infant newly diagnosed with Hemophilia?

• A. immobility
• B. altered growth and development
• C. hemarthrosis
• D. altered family processes

Correct answer: D

Rationale: Altered Family Processes play a significant role in impacting the body image of an infant newly diagnosed with Hemophilia. Infants are highly perceptive of their caregivers' responses, and any changes in family dynamics due to the diagnosis can affect the infant's sense of security and trust, influencing their body image and self-perception. Immobility, while a long-term effect of hemophilia, is not an immediate impact on body image. Altered growth and development would not have manifested immediately post-diagnosis. Hemarthrosis, characterized by bleeding into joint spaces, is a hallmark of hemophilia but does not directly influence body image in the immediate aftermath of a new diagnosis.

4. 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.

5. The LPN needs to determine the client's respiratory rate. What is the best technique to do this?

• A. Tell the client you need to count their respiratory rate.
• B. Subtly watch the client from across the room when they are doing an activity.
• C. Ask the client to sit still for 30 seconds.
• D. Count respirations while pretending to check the client's pulse.

Correct answer: D

Rationale: The best technique to determine a client's respiratory rate is to count respirations while pretending to check the client's pulse. You should not inform the client that you are counting their respirations, as this might lead to a change in their breathing pattern. Pretending to check the pulse allows you to be close to the client without revealing that you are assessing their respiratory rate. Asking the client to sit still may not be as effective, as it may cause them to concentrate on their breathing. Watching from across the room may not provide an accurate assessment of respirations, as they might be difficult to observe.
