Correct Answer: B

Rationale: The correct answer is B: Disseminated intravascular coagulation (DIC). In DIC, there is widespread activation of coagulation leading to consumption of clotting factors, resulting in prolonged PT and aPTT, low fibrinogen levels, and elevated D-dimer. This pattern matches the laboratory findings in the patient. In liver cirrhosis (choice A), there is a decrease in clotting factors synthesis, leading to prolonged PT but not aPTT. Hemophilia A (choice C) is a genetic disorder that affects specific clotting factors, typically leading to prolonged aPTT but not PT. Vitamin K deficiency (choice D) impairs the synthesis of clotting factors, leading to prolonged PT but not aPTT and low levels of factors II, VII, IX, and X.

Correct Answer: A

Rationale: Rationale: A is the correct answer as it demonstrates therapeutic communication by encouraging Annie to express her feelings and fears. It shows empathy and understanding, allowing Annie to elaborate on her concerns. B is incorrect as it dismisses Annie's fears and implies blame on her parenting. C is incorrect as it focuses on the behavior of the children rather than addressing Annie's emotions. D is incorrect as it places the responsibility on the children to make Annie feel comfortable, rather than addressing her concerns directly.

Correct Answer: C

Rationale: The correct answer is C: Food and water. Typhoid fever is primarily transmitted through contaminated food and water by the bacterium Salmonella typhi. The bacteria are shed in the feces of infected individuals and can contaminate water sources or food prepared with contaminated water. This transmission route aligns with the typical epidemiology of typhoid fever outbreaks. Now, let's discuss why the other choices are incorrect: A: A vector - Typhoid fever is not transmitted by a vector such as mosquitoes or ticks. B: Blood and body fluids - Typhoid fever is not typically spread through blood or body fluids but rather through ingestion of contaminated food or water. D: Air - Typhoid fever is not an airborne disease and is not transmitted through the air.

Correct Answer: B

Rationale: The correct answer is B: establish a credit body of evidence to support and improve the delivery of care. Conducting research in nursing aims to generate a robust evidence base to inform and enhance the quality of care provided to patients. This evidence helps in identifying best practices, improving patient outcomes, and advancing the nursing profession as a whole. Choice A is incorrect because the main goal of research is not to solely justify the role of nurses, but rather to improve care delivery. Choice C is incorrect as the goal is not to justify an oversupply of nurses, but to address healthcare needs effectively. Choice D is incorrect because the focus of nursing research is on nursing-related issues, not non-nursing problems.

Correct Answer: C

Rationale: The correct answer is C, to have a limited intake of sodium. Lithium can lead to increased sodium levels in the body, potentially causing toxicity. By limiting sodium intake, the patient can maintain a balance and prevent adverse effects. Choice A is incorrect as tyramine content is not directly related to lithium intake. Choice B is incorrect as fluid intake does not have a significant impact on lithium levels. Choice D is incorrect because an adequate intake of sodium can lead to worsening lithium toxicity.
