Nursing Elites

1. 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.

2. What is the therapeutic range for carbamazepine (Tegretol)?

• A. 7-12 mcg/mL
• B. 4-10 mcg/mL
• C. 10-14 mcg/mL
• D. 1-5 mcg/mL

Correct answer: B

Rationale: The therapeutic range for carbamazepine (Tegretol) is 4-10 mcg/mL. This range is established based on the optimal balance between effectiveness and safety. Choices A, C, and D are outside the therapeutic range for carbamazepine, which could lead to suboptimal treatment outcomes or increased risk of toxicity. Choice B (4-10 mcg/mL) is the correct range recommended for therapeutic efficacy while minimizing adverse effects.

3. A nurse assisting with data collection of the peripheral vascular system performs the Allen test. The nurse understands that this test is used to determine the patency of which blood vessel(s)?

• A. Capillaries
• B. Pedal pulses
• C. Femoral arteries
• D. Radial and ulnar arteries

Correct answer: D

Rationale: The nurse performs the Allen test to determine the patency of the radial and ulnar arteries. During the test, the nurse applies pressure over the client's ulnar and radial arteries simultaneously. The client is then asked to open and close the hand repeatedly, causing the hand to blanch. Subsequently, the nurse releases pressure from the ulnar artery while compressing the radial artery and checks the color of the extremity distal to the pressure point. If pinkness fails to return within 6 seconds, it indicates that the ulnar artery is insufficient, suggesting that the radial artery should not be used for obtaining a blood specimen. Choice A (Capillaries) is incorrect as the Allen test assesses the patency of larger arteries, not capillaries. Choice B (Pedal pulses) is incorrect as the Allen test specifically evaluates the radial and ulnar arteries, not the pedal pulses in the foot. Choice C (Femoral arteries) is incorrect as the Allen test focuses on the radial and ulnar arteries in the hand, not the femoral arteries in the leg.

4. 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.

5. A nurse preparing to assist with data collection of the abdomen asks the client to void and then assists the client into a supine position. Which primary finding does the nurse expect to note on percussing all four quadrants of the abdominal cavity?

• A. Dullness
• B. Tympany
• C. Borborygmus
• D. Hyperresonance

Correct answer: B

Rationale: The nurse expects to primarily note tympany when percussing the abdomen. Tympany should predominate because air in the intestines rises to the surface when the client is in a supine position. Dullness is usually heard over a distended bladder, adipose tissue, fluid, or a mass. Borborygmus, which refers to hyperperistalsis, is typically heard on auscultation, not percussion. Hyperresonance is present with gaseous distention, not the typical finding when percussing all four quadrants of the abdomen.
