1. Which lab value is critical to monitor in patients receiving warfarin therapy?

Correct answer: A

Rationale: The correct answer is A: Monitor INR. INR (International Normalized Ratio) is crucial to monitor in patients receiving warfarin therapy. INR measures the blood's ability to clot and is used to ensure that patients are within the therapeutic range for warfarin therapy. This is important to prevent both clotting disorders and bleeding complications. Monitoring potassium levels (choice B) is not directly related to warfarin therapy. Platelet count (choice C) and sodium levels (choice D) are important parameters but are not as critical to monitor specifically for patients on warfarin therapy.

2. A healthcare provider is assessing a client who takes Desmopressin for Diabetes Insipidus. For which of the following adverse effects should the healthcare provider monitor?

Correct answer: D

Rationale: The correct answer is D: Headache. Headache during desmopressin therapy can indicate water intoxication, which is a potential adverse effect. Desmopressin is a medication used to treat Diabetes Insipidus by reducing excessive urination and thirst. Monitoring for headaches is crucial as it can signal decreased sodium levels due to water retention, leading to water intoxication, which is a serious concern. Hypovolemia, hypercalcemia, and agitation are not typically associated with desmopressin therapy for Diabetes Insipidus.

3. The rationales for using a prostaglandin gel for a client prior to the induction of labor is to:

Correct answer: C

Rationale: Effective nursing care involves comprehensive assessments that address all aspects of a patient's condition, ensuring that interventions are appropriately targeted and outcomes are optimized.

4. The nurse teaches the mother of an infant how to care for her infant following repair of a cleft lip. It is MOST important for the nurse to include which of the following instructions?

Correct answer: D

Rationale: The correct answer is D because feeding the infant with a rubber-tipped syringe reduces the risk of injury to the surgical site and prevents aspiration. Choice A is incorrect because feeding in the recumbent position can increase the risk of aspiration. Choice B is incorrect as Betadine is not recommended for wound care near the mouth due to its potential toxicity if ingested. Choice C is incorrect because placing the infant in the prone position after feeding can increase the risk of regurgitation and aspiration.

5. Which of the following is a process of heat loss that involves 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. Radiation (Choice A) is the transfer of heat through electromagnetic waves, while convection (Choice C) is the transfer of heat through the movement of fluids. Evaporation (Choice D) is a cooling process that involves the phase change of a liquid into a gas.
