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. Which of the following methods of contraception is able to reduce the transmission of HIV and other STDs?

• A. intrauterine device (IUD)
• B. Norplant
• C. oral contraceptives
• D. vaginal sponge

Correct answer: D

Rationale: The correct answer is the vaginal sponge. The vaginal sponge, when used with foam or jelly contraception, acts as a barrier method that can reduce the transmission of HIV and other STDs, in addition to preventing pregnancy. In contrast, IUDs, Norplant, and oral contraceptives are effective in preventing pregnancy but do not provide protection against the transmission of HIV and STDs. IUDs prevent pregnancy by affecting sperm movement and survival, Norplant releases hormones to prevent ovulation, and oral contraceptives work by inhibiting ovulation. However, these methods do not create a physical barrier against HIV and STD transmission. It is important to counsel clients using methods like IUDs, Norplant, and oral contraceptives to also use chemical or barrier contraceptives to lower the risk of HIV or STD transmission.

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. A nurse is trying to motivate a client toward more effective management of a therapeutic regimen. Which of the following actions by the nurse is most likely to be effective in increasing the client's motivation?

• A. determining if the client has any family or friends living nearby
• B. developing a concise discharge plan and reviewing it with the client
• C. teaching the client about the disorder at the client's level of understanding
• D. making a referral to an area agency for client follow-up

Correct answer: C

Rationale: To effectively motivate the client, it is important to educate them about the disorder at their level of understanding. This helps the client comprehend the importance of the therapeutic regimen and empowers them to actively participate in their treatment. Choice A, determining if the client has any family or friends living nearby, may provide social support but is less likely to directly impact the client's motivation compared to educating them about their condition. Developing a concise discharge plan, as in choice B, is crucial for continuity of care but may not directly enhance the client's motivation as effectively as providing education tailored to their level of understanding. Making a referral for follow-up, as in choice D, is important for ongoing care but may not have the same immediate impact on the client's motivation as educating them about their condition.

5. A client complains that her skin is redder than normal. The nurse notes the client's skin, documents hyperemia, and explains to the client that this condition is caused by which factor?

• A. Constriction of the underlying blood vessels
• B. An increased amount of bilirubin in the blood
• C. Increased perfusion of the surrounding tissues
• D. Excess blood in the dilated superficial capillaries

Correct answer: D

Rationale: Hyperemia is an excess of blood in a part of the body. The skin over a hyperemic area usually becomes reddened or warm. The condition is caused by increased blood flow, local relaxation of arterioles, or obstruction of the outflow of blood from an area. Choice A is incorrect because constriction of blood vessels would lead to decreased blood flow, not excess blood. Choice B is incorrect as an increased amount of bilirubin in the blood is related to jaundice, not hyperemia. Choice C is incorrect because increased perfusion of the surrounding tissues would cause redness, not hyperemia.
