Correct Answer: B

Rationale: The correct action for the nurse to take when caring for a client with Clostridium difficile infection is to place the client on contact precautions. This helps prevent the spread of the infection to other clients. Washing hands with an alcohol-based hand rub is important for infection control but is not specific to preventing the spread of Clostridium difficile. Wearing a mask may be necessary for airborne precautions but is not the priority for Clostridium difficile infection. Double-bagging linens is not a standard practice for preventing the spread of Clostridium difficile.

Correct Answer: C

Rationale: The correct answer is C. Pacing spikes after the QRS complex indicate a malfunction of the pacemaker and should be reported. Choice A is not directly related to the pacemaker function. Choice B, hiccups, are common and not typically associated with pacemaker issues. Choice D, a heart rate of 90 beats per minute, is within the normal range and does not indicate a pacemaker malfunction.

Correct Answer: B

Rationale: In this scenario, the appropriate action for the nurse to take when a client reports severe postoperative pain of 8 out of 10 is to administer oxycodone 10 mg PO. Oxycodone is a potent analgesic that is more effective in managing severe pain compared to ibuprofen, making choice A incorrect. Repositioning the client to the unaffected side or applying a cold compress may provide some comfort but are not the priority interventions for severe postoperative pain, making choices C and D less appropriate.

Correct Answer: C

Rationale: The correct statement the nurse should include is to take one nitroglycerin sublingual tablet every 5 minutes until the pain is relieved, up to three doses. This dosing regimen is important to manage angina attacks effectively. Option A is incorrect because nitroglycerin sublingual tablets should not be taken with water. Option B is incorrect as nitroglycerin tablets should be stored in their original container at room temperature. Option D is incorrect because there is no specific instruction to avoid foods high in sodium while taking nitroglycerin sublingual tablets.

Correct Answer: A

Rationale: Confirming the client's perception of the event is crucial in understanding how they are interpreting the crisis situation. This helps the nurse gain insight into the client's perspective, emotions, and needs. By validating the client's perception, the nurse can establish trust and rapport, which are essential in providing effective support during a crisis. Notifying the client's support system (Choice B) may be important but should come after understanding the client's perspective. Helping the client identify personal strengths (Choice C) and teaching relaxation techniques (Choice D) are valuable interventions but should follow the initial step of confirming the client's perception to ensure individualized care.
