1. Which of the following describes a process of heat loss involving the transfer of heat from one surface to another?

Correct answer: B

Rationale: Conduction is the process of heat transfer that occurs between objects or substances that are in direct contact with each other. In this process, heat is transferred from a hotter surface to a cooler surface through direct contact. This type of heat transfer does not involve the movement of the substances themselves, only the transfer of thermal energy. Choice A, Radiation, is the transfer of heat in the form of electromagnetic waves and does not require a medium. Choice C, Convection, involves the transfer of heat through the movement of fluids (liquids or gases) due to density differences. Choice D, Evaporation, is a cooling process that involves the transformation of a liquid into a gas, absorbing heat in the process.

2. The client has failed to conceive after many attempts over a three-year time period and asks the nurse, “I have tried everything. What should I do now?” Which statement is the nurse’s best response?

Correct answer: A

Rationale: The nurse's best response should focus on providing empathetic support and guiding the client to explore further options, such as fertility specialists or treatments. Assessing intravenous fluids for rate and volume is not relevant to the client's concern about infertility. Changing surgical dressing, monitoring medication levels, and tracking meal intake are all unrelated to the client's fertility issues.

3. Warfarin (Coumadin) is an anticoagulant and interferes with the action of:

Correct answer: B

Rationale: The correct answer is B: Vitamin K. Warfarin inhibits the action of vitamin K, which is essential for blood clotting. By interfering with the production of certain clotting factors, warfarin helps prevent blood clots. Choices A, C, and D are incorrect because warfarin primarily affects the vitamin K-dependent clotting factors and not platelets, calcium, or vitamin B12.

4. Short-bowel syndrome usually occurs when:

Correct answer: B

Rationale: Short-bowel syndrome usually occurs when more than 50% of the small intestine is surgically removed. This condition results in malabsorption of nutrients and fluids due to the reduced length of the small intestine. Choice A is incorrect because the contraction of longitudinal muscles does not lead to short-bowel syndrome. Choice C is incorrect as short-bowel syndrome is primarily related to the small intestine, not the large intestine. Choice D is incorrect since decreased transit time due to infection or drugs is not a direct cause of short-bowel syndrome.

5. A client has been given instructions about ferrous sulfate. Which statement made by the client would indicate the client needs further education?

Correct answer: A

Rationale: The correct answer is A. Ferrous sulfate should be taken on an empty stomach to improve absorption. Choice A is incorrect as taking the medication with a full glass of milk would impair iron absorption. Choices B, C, and D are all correct statements regarding the administration of ferrous sulfate. Choice B ensures proper timing before breakfast, choice C highlights avoiding coffee due to interference with iron absorption, and choice D correctly suggests taking antacids a few hours after ferrous sulfate to prevent potential interactions.
