Nursing Elites

1. A pregnant client asks how she can prevent getting Group B Strep. What is the LPN's best response?

• A. You cannot prevent getting Group B Strep; you can only treat it.
• B. You should have your partner wear a condom every time you have intercourse.
• C. You should be extra vigilant about hand-washing, especially in the third trimester.
• D. The Group B Strep vaccine is the only proven way to prevent the disease.

Correct answer: A

Rationale: The best response for the LPN to provide to a pregnant client concerned about preventing Group B Strep is that it cannot be prevented, only treated. Group B Strep is a normal flora found in the vagina, rectum, and intestines of about 25% of women and is not a sexually transmitted disease. Testing for Group B Strep is done in each pregnancy, usually around 35-37 weeks. If a woman tests positive, antibiotics are administered during labor to reduce the risk of complications for both the mother and the baby. Choice A is the correct answer as Group B Strep cannot be prevented but only treated. Choice B is incorrect; condom use does not prevent Group B Strep. Choice C is not the best response as hand-washing is important for general hygiene but does not specifically prevent Group B Strep. Choice D is incorrect as there is no vaccine available to prevent Group B Strep.

2. A nurse is preparing to assess the dorsalis pedis pulse. The nurse palpates this pulse by placing the fingertips in which location?

• A. Behind the knee
• B. Lateral to the extensor tendon of the big toe
• C. In the groove between the malleolus and the Achilles tendon
• D. Below the inguinal ligament, halfway between the pubis and the anterior superior iliac spines

Correct answer: B

Rationale: The correct location to palpate the dorsalis pedis pulse is lateral to and parallel with the extensor tendon of the big toe. Choices A, C, and D describe the locations for other pulses - popliteal, posterior tibial, and femoral artery respectively. The popliteal pulse is found behind the knee, the posterior tibial pulse is located in the groove between the malleolus and the Achilles tendon, and the femoral artery is situated below the inguinal ligament, halfway between the pubis and the anterior superior iliac spines.

3. What effect can medication bound to protein have?

• A. reduced drug availability
• B. limited distribution of the drug to receptor sites
• C. less availability to produce desired medicinal effects
• D. decreased metabolism of the drug by the liver

Correct answer: C

Rationale: Medication bound to protein leads to less availability to produce desired medicinal effects because only unbound drugs can interact with active receptor sites. If a drug is bound to protein, it cannot bind with a receptor site, reducing its effectiveness. Choice A is incorrect because binding to protein reduces drug availability. Choice B is incorrect because distribution to receptor sites is ineffective if the drug is bound to protein. Choice D is incorrect because metabolism does not occur until the drug is removed from the protein molecule by the liver, allowing the protein to return to circulation.

4. The nurse is teaching parents of a newborn about feeding their infant. Which of the following instructions should the nurse include?

• A. Use the defrost setting on microwave ovens to warm bottles.
• B. When refrigerating formula, discard partially used bottles after 24 hours.
• C. When using formula concentrate, mix one part water and one part concentrate.
• D. When using powdered formula, mix two parts water and one part powder.

Correct answer: A

Rationale: The correct answer is to use the defrost setting on microwave ovens to warm bottles. It is essential for parents to be cautious when warming bottles in a microwave oven to prevent superheating of the milk. Choosing the defrost setting and checking the formula temperature before giving it to the baby helps avoid burns. Discarding partially used bottles after 24 hours when refrigerating formula is crucial as it reduces the risk of harmful bacterial growth. Mixing formula concentrate with water in a 1:1 ratio of one part concentrate to one part water ensures proper dilution of the formula. On the other hand, powdered formula should be mixed following the package instructions, typically using two parts water to one part powder. This accurate mixing ratio provides the necessary balance of nutrients for the baby. Adding fresh formula to partially used bottles can introduce pathogens that may harm the infant, underscoring the importance of discarding partially used bottles and preparing formula correctly. Therefore, options B, C, and D are incorrect as they do not address the safe and proper ways to feed a newborn effectively.

5. 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.
