Correct Answer: B

Rationale: The correct answer is B: decrease resident intestinal flora. Lactulose is a synthetic sugar that is not absorbed in the intestine and is used to decrease ammonia levels in patients with hepatic encephalopathy by promoting the growth of beneficial gut bacteria that help metabolize ammonia. This action helps reduce the toxic effects of ammonia on the brain. A: prevent constipation - Lactulose may help with constipation, but its primary action in this scenario is to decrease resident intestinal flora. C: increase intestinal peristalsis - Lactulose does not directly increase peristalsis. D: prevent portal hypertension - Lactulose does not have a direct effect on preventing portal hypertension.

Correct Answer: B

Rationale: The correct answer is B: Wash and inspect the feet daily. This is important for clients with diabetes mellitus to prevent complications like foot ulcers. Daily foot care helps detect any issues early. Choice A is incorrect as it is not recommended to use commercial preparations without medical advice. Choice C is incorrect as walking barefoot can increase the risk of injury and infection. Choice D is incorrect as cutting toenails by rounding edges can lead to ingrown toenails, which can be dangerous for clients with diabetes.

Correct Answer: A

Rationale: The correct answer is A: A-positive blood to an A-negative client. This is because in ABO blood typing, individuals with blood type A have anti-B antibodies in their plasma. Therefore, if A-positive blood (which contains the A antigen) is given to an A-negative client (who has anti-A antibodies), there is a high risk of an acute hemolytic reaction due to the antibodies attacking the transfused blood cells. Choices B, C, and D are incorrect because they do not involve a mismatch of ABO blood types that would lead to a significant risk of acute hemolytic reaction. In choice B, O-positive blood can be safely transfused to an A-positive client as O blood is considered the universal donor. In choice C, O-negative blood can be safely given to an O-positive client as O-negative blood is compatible with all blood types. In choice D, B-positive blood can be safely administered to an AB-positive client as the AB blood type can receive both

Correct Answer: A

Rationale: The correct answer is A because protocols are indeed guidelines that assist clinicians in decision-making and choosing interventions for specific health care problems. This definition accurately reflects the purpose and function of protocols in nursing practice. Option B is incorrect as it describes protocols as policies related to nurses' duties and standards of care, which is more aligned with job descriptions and policies rather than protocols. Option C is incorrect as it relates protocols to a code of ethics, which is a separate concept that guides ethical decision-making and behavior in nursing practice. Option D is incorrect as it inaccurately describes protocols as prescriptive order forms, which are actually separate from protocols and are used for medication administration and treatment orders.

Correct Answer: C

Rationale: The correct answer is C: Alteration in tissue perfusion related to bleeding and diminished blood flow. Disseminated intravascular coagulation (DIC) is a condition where blood clots form throughout the body, leading to both bleeding and clotting. This can result in decreased blood flow to tissues, causing tissue perfusion issues. Explanation: 1. Option A: Risk for increased cardiac output related to fluid volume excess is incorrect because DIC can lead to bleeding, causing a decrease in blood volume and potentially decreasing cardiac output. 2. Option B: Disturbed sensory perception related to bleeding into tissues is incorrect as DIC primarily affects blood clotting and bleeding, not sensory perception. 3. Option D: Risk for aspiration related to constriction of the respiratory musculature is incorrect as DIC does not directly cause constriction of respiratory muscles, but rather impacts the clotting and bleeding processes in the body. In summary, the correct answer is C because DIC can lead to altered tissue perfusion
