Correct Answer: B

Rationale: Obtaining a peripheral O2 saturation reading is the priority intervention in this scenario. It helps assess the client's oxygenation status quickly, which is crucial in a client with signs of respiratory distress, such as shortness of breath and bilateral pulmonary crackles. Ordering a chest X-ray (Choice A) may be necessary later but does not address the immediate need for oxygen assessment. Obtaining an order for a complete blood count (Choice C) is not the priority in this situation as it does not directly address the client's respiratory distress. Instructing the patient to stay in bed (Choice D) does not address the underlying issue of potential hypoxia and respiratory compromise.

Correct Answer: D

Rationale: The best strategy for the nurse to use when teaching insulin injection techniques to a newly diagnosed client with diabetes is to observe a return demonstration. This method ensures that the client can correctly perform the technique. Providing written pre and post tests (choice A) may assess knowledge but not application. Asking questions during practice (choice B) may help with understanding but not necessarily with the actual performance. Allowing another diabetic to assist (choice C) may provide peer support but does not guarantee correct technique demonstration.

Correct Answer: C

Rationale: Consulting with human resources is the best approach in this situation. It ensures that the issue is handled according to the organization's policies and that the nurse receives the appropriate support and intervention needed for chemical dependency. Confronting the nurse directly may lead to defensiveness and hinder a constructive resolution. Scheduling a staff conference without the nurse present can create unnecessary speculation and violate the employee's privacy. Counseling the employee to resign is not appropriate and does not address the underlying problem of chemical dependency.

Correct Answer: C

Rationale: Individuals with cognitive impairment often experience difficulties in learning new information, creative thinking, and making sound judgments. Loss of ability in hearing, speech, and sight (Choice A) is more closely related to sensory impairments rather than cognitive impairment. Endurance, strength, and mobility (Choice B) are more associated with physical capabilities rather than cognitive functions. Balance, flexibility, and coordination (Choice D) are related to motor skills and physical coordination, not cognitive impairment.

Correct Answer: B

Rationale: Under the present system, the local government unit is responsible for all the listed activities. This includes the operation and maintenance of health facilities, implementation of health programs/projects, and delivery of health services. Therefore, choice B, 'All of these activities,' is the correct answer. Choices A, C, and D are incorrect because they are all responsibilities that fall under the local government unit's jurisdiction as well.
