Which intervention reduces reservoirs of infection in a healthcare setting?

Correct Answer: A

Rationale: Placing capped needles and syringes in puncture-resistant containers is the correct intervention to reduce infection reservoirs in healthcare settings. This practice helps prevent accidental needle-stick injuries and contains potentially infectious materials properly. Keeping bedside table surfaces clean and dry (choice B) is essential for preventing the spread of infections but does not directly address reducing reservoirs of infection. Changing dressings that become wet or soiled (choice C) is important for wound care but does not specifically target infection reservoirs. Placing tissues and soiled dressings in paper bags (choice D) is a proper waste disposal practice but does not directly reduce reservoirs of infection in a healthcare setting.

Correct Answer: B

Rationale: Correct hand hygiene is crucial for preventing the spread of infections and ensuring patient safety. When a nurse observes another healthcare worker skipping hand hygiene practices, it is essential to report this behavior to the supervisor. Reporting ensures that appropriate action is taken to address the issue and maintain a safe environment for patients. Ignoring the situation (Choice A) may compromise patient safety. Discussing the issue directly with the nurse (Choice C) may not always be effective in ensuring compliance. Doing nothing and continuing with patient care (Choice D) disregards the importance of infection control protocols.

Correct Answer: B

Rationale: The correct answer is to place the patient in a high Fowler's position. This position helps improve lung expansion and oxygenation in cases of pulmonary edema by reducing venous return to the heart and enhancing respiratory mechanics. Administering a diuretic (Choice A) can be important but is not the priority over positioning in this situation. Administering oxygen (Choice C) is essential, but the priority action for improving oxygenation is the positioning of the patient. Monitoring lung sounds (Choice D) is crucial for ongoing assessment but is not the priority action when the patient is in distress with pulmonary edema.

Correct Answer: A

Rationale: The correct answer is A. The sink is considered a contaminated area. When hand hygiene is compromised during the process, it is essential to repeat handwashing using antiseptic soap to ensure proper hygiene. Choice B is incorrect because the situation can be managed by proper handwashing. Choice C is incorrect as extending the handwashing procedure to 5 minutes is not necessary in this scenario. Choice D is incorrect as the hands need to be properly cleaned before assisting the healthcare provider.

Correct Answer: C

Rationale: Elevating the head of the bed to 30-45 degrees is the most appropriate intervention to prevent aspiration in a patient with an NG tube. This position helps reduce the risk of regurgitation and aspiration by promoting the proper flow of contents through the gastrointestinal tract and minimizing the chances of stomach contents entering the airway. Flushing the NG tube with water before each feeding may not directly prevent aspiration. Checking the placement of the NG tube is important but does not specifically address the prevention of aspiration. Providing oral care every 4 hours is essential for maintaining oral hygiene but is not directly related to preventing aspiration in a patient with an NG tube.

Correct Answer: B

Rationale: The correct answer is to assist the patient to sit down slowly. This intervention is appropriate for a patient experiencing dizziness when standing up, as it helps prevent falls due to orthostatic hypotension. Encouraging deep breaths (Choice A) may not address the underlying cause of dizziness, which is related to postural changes. Instructing the patient to use a walker for support (Choice C) or teaching the patient how to change positions safely (Choice D) are not the most immediate and direct interventions to address the immediate risk of falling when feeling dizzy upon standing.

Correct Answer: C

Rationale: The primary purpose of turning and repositioning an immobile patient every 2 hours is to prevent skin breakdown and pressure ulcers. Prolonged immobility can lead to pressure ulcers, making this a crucial nursing intervention. Choice A is incorrect because while turning can help improve circulation and relieve pressure, the primary purpose is to prevent skin breakdown. Choice B is incorrect as preventing contractures and muscle atrophy is important but not the primary purpose of turning. Choice D is incorrect as improving respiratory function and preventing pneumonia are not directly related to turning and repositioning for skin integrity.

Correct Answer: B

Rationale: The correct answer is B. The nurse can safely remove restraints once no aggressive behavior is observed after releasing two extremity restraints for an hour. Choice A is incorrect because the removal of restraints should be based on the client's behavior rather than just the effect of medication. Choice C is incorrect as exploring reasons for aggressive behavior should be done before or during the intervention, not as a condition for removing restraints. Choice D is incorrect since an apology from the client does not guarantee a change in behavior or indicate that it is safe to remove the restraints.

Correct Answer: B

Rationale: Verifying the patient's identity using two identifiers is crucial to ensure the right patient receives the right medication. This process helps prevent medication errors by confirming the patient's identity through at least two unique identifiers, such as name, date of birth, or medical record number. Choice A is not directly related to ensuring patient safety during medication administration. Choice C is incorrect as medications should be prepared in a sterile environment, not just at the healthcare professional's station. Choice D is not a safe practice as medications should be administered at the scheduled time to maintain therapeutic effectiveness.
