Correct Answer: B

Rationale: The correct answer is B: 'Flush the NG tube before and after each medication.' Flushing the NG tube is essential to ensure that the medication passes through smoothly without any obstruction. It helps prevent clogging of the tube and ensures that the full dose of the medication reaches the patient. Options A, C, and D are incorrect because crushing all medications at once, administering only liquid forms of medications, and skipping tube flushing entirely can lead to complications such as tube blockages, incomplete medication administration, and potential harm to the client.

Correct Answer: C

Rationale: The correct answer is C. Using a clean technique for inserting a urinary catheter increases the risk for healthcare-associated infections. Invasive procedures like catheter insertion require a sterile technique to prevent introducing pathogens into the urinary tract. Choices A and B demonstrate appropriate infection control measures by emphasizing the use of sterile or aseptic techniques. Choice D represents an incorrect technique that can lead to the introduction of bacteria from the rectum into the urinary tract, potentially causing infections.

Correct Answer: B

Rationale: When a nurse observes a colleague behaving strangely, the best course of action is to report the behavior to the supervisor. Unusual behavior by a healthcare professional could compromise patient safety and should be addressed promptly. Ignoring the behavior (Choice A) could potentially lead to negative outcomes for patients. Asking the colleague directly (Choice C) may not be appropriate if the behavior poses a risk. Discussing the behavior with other colleagues (Choice D) may not directly address the issue and could lead to gossip rather than a resolution.

Correct Answer: D

Rationale: During a potential bioterrorism attack, the priority for the nurse is to manage all patients using standard precautions. This approach ensures the safety of both patients and healthcare providers by preventing the spread of potential bioterrorism-related illnesses. Option A is incorrect because managing patient care and safety through standard precautions takes precedence. Option B is incorrect as patient transport should also be done while adhering to infection control measures. Option C is incorrect as monitoring for specific symptoms is important but not the priority when all patients need to be managed with standard precautions.

Correct Answer: C

Rationale: The correct answer is C: 'Do you have a chronic disease?' Patients with chronic diseases are more susceptible to infections due to factors like general debilitation and nutritional impairment. Choices A, B, and D are incorrect because having children in the home, having a spouse, or religious beliefs do not directly impact susceptibility to infectious diseases.
