Correct Answer: D

Rationale: The correct answer is D: Draw up clear insulin first when mixing two types of insulin in one syringe. This is important because mixing insulin requires drawing up the clear (short-acting) insulin first to prevent contamination. This ensures accurate dosing and prevents clouding of the insulin. Drawing up cloudy insulin first can lead to inaccurate dosing and potential mixing errors. Administering insulin after the first meal (choice A) is not the focus of this question. Administering insulin at a 45-degree angle into the deltoid muscle (choice B) is not recommended for insulin injections. Vigorously shaking the vial of insulin before withdrawal (choice C) can cause bubbles and affect the accuracy of the dose.

Correct Answer: D

Rationale: The correct answer is D (Lamb and peaches) because lamb is a good source of heme iron, which is more easily absorbed by the body compared to non-heme iron found in plant-based foods. Peaches are high in vitamin C, which enhances iron absorption. Shrimp and tomatoes (A) have some iron but are not as rich in iron as lamb. Cheese and bananas (B) are not significant sources of iron. Lobster and squash (C) also do not provide as much iron as lamb. Overall, the combination of heme iron from lamb and vitamin C from peaches makes them the most suitable choices for an anemic client requiring iron therapy.

Correct Answer: D

Rationale: The correct answer is D: Dependent. In this scenario, the nurse is administering pain medication based on a healthcare provider's prescription, which demonstrates a dependent nursing intervention. The nurse is reliant on the provider's order to carry out this action. Collaborative interventions involve working with other healthcare professionals, independent interventions are actions that nurses can initiate without supervision, and interdependent interventions involve mutual goal-setting and decision-making among healthcare team members.

Correct Answer: A

Rationale: The correct answer is A: “Be sure to take glipizide 30 minutes before meals.” This instruction is correct because glipizide is an oral antidiabetic agent that works best when taken before meals to help control blood glucose levels. Taking it before meals allows the medication to coincide with the body's natural insulin response to food intake, thereby improving its effectiveness. Choice B is incorrect because glipizide does not typically cause low serum sodium levels, so there is no need for monthly sodium level checks. Choice C is incorrect because it is essential for the client to continue monitoring their blood glucose levels even after starting glipizide to ensure the medication is working effectively. Choice D is incorrect because taking glipizide after a meal will not optimize its effectiveness in controlling blood glucose levels.

Correct Answer: A

Rationale: The correct answer is A: Surgery. Surgery is the primary treatment for vaginal cancer, especially for early-stage cases. It involves removing the cancerous tissue from the vagina. Radiation (B) and chemotherapy (C) may also be used in addition to surgery in some cases, but they are not the primary treatment. Immunotherapy (D) is not a standard treatment for vaginal cancer. It is important to prioritize surgery as it directly targets and removes the cancerous cells from the affected area, increasing the chances of successful treatment and recovery.
