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. The parents of a 2-year-old child ask the nurse how they can teach their child to stop taking toys away from other children. Which of the following statements by the nurse offers the parents the best explanation of their child's behavior?

• A. "Your child is egocentric. Egocentricity is normal for 2-year-old children. He believes other children want him to have their toys."?
• B. "Your child is showing negativity. He doesn't want other children to have the toys he wants."?
• C. "Your child is demonstrating magical thinking. He believes he can make the other children want him to play with their toys."?
• D. "Your child is engaging in domestic imitation. He is doing what he has seen other children do."?

Correct answer: A

Rationale: Two-year-old children are very egocentric, believing everything revolves around them. They think other children want them to have their toys, which explains why they may take toys from others. This behavior is typical for children at this age as they lack the ability to see things from another's perspective. Option B is incorrect because negativity in children this age is more related to refusal of requests rather than taking toys. Magical thinking, as described in option C, is usually seen in preschool-age children and involves unrealistic beliefs. Option D is incorrect as domestic imitation refers to imitating adult household tasks, not other children's behavior.

3. The LPN is caring for a client taking Lipitor (Atorvastatin). Which of these statements would indicate that the client may need reinforced teaching?

• A. "I take my Lipitor with a glass of milk after my breakfast."?
• B. "I take my Lipitor and wait 30 minutes before taking my other medications."?
• C. "I take my Lipitor 30 minutes after I eat something."?
• D. "I take my Lipitor and my other morning medications with my grapefruit juice at breakfast."?

Correct answer: D

Rationale: The correct answer is, 'I take my Lipitor and my other morning medications with my grapefruit juice at breakfast.' This statement indicates a need for reinforced teaching because grapefruit juice should be avoided when taking Lipitor. Grapefruit juice blocks the enzymes needed to break down the drug, which leads to excessive amounts of the drug in the body. Choices A, B, and C show appropriate timing and administration of Lipitor, whereas choice D poses a potential risk due to the interaction between grapefruit juice and Lipitor.

4. A healthcare professional reviewing a client's record notes documentation that the client has melena. How does the healthcare professional detect the presence of melena?

• A. By checking the client's urine for blood
• B. By checking the client's stool for blood
• C. By checking the client's urine for a decrease in output
• D. By checking the client's bowel movements for diarrhea

Correct answer: B

Rationale: Melena' is the term used to describe abnormal black tarry stool that has a distinctive odor and contains digested blood. It usually results from bleeding in the upper gastrointestinal tract and is often a sign of peptic ulcer disease or small bowel disease. The presence of melena is detected by checking the client's stool for blood. Blood in the client's urine, decreased urine output, and diarrhea are not associated with the assessment for melena.

5. 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.
