Correct Answer: C

Rationale: The correct answer is C: Immediate recognition of respiratory distress. This is crucial when caring for a client with influenza as the virus can lead to respiratory complications. Prompt recognition allows for timely intervention and prevents further deterioration. A: Maintaining airborne transmission is incorrect as the goal is to prevent the spread of influenza through droplet precautions, not airborne transmission. B: Oxygen administration may be necessary for severe cases of influenza, but immediate recognition of respiratory distress takes precedence in the nursing interventions. D: Complete bed rest is not recommended for influenza as mobilization and deep breathing exercises are important to prevent complications like pneumonia.

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: 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: 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: D

Rationale: Step 1: Define nonmodifiable risk factors - these are factors that cannot be changed or controlled by the individual. Step 2: Advanced age is a nonmodifiable risk factor as it is determined by genetics and time. Step 3: Poor control of blood glucose levels, foot trauma, and inappropriate foot care are modifiable risk factors that can be managed through lifestyle changes or medical interventions. Summary: Choice D is correct because advanced age is a nonmodifiable risk factor for diabetes mellitus, while the other choices involve factors that can be modified through appropriate actions.
