Correct Answer: A

Rationale: In the presence of moderate, persistent, chronic neuropathic pain, the WHO pain relief ladder recommends continuing gabapentin, as it is effective for managing both anxiety and pain. Ibuprofen, a nonsteroidal anti-inflammatory drug, is not the mainstay for neuropathic pain relief according to the ladder and can be discontinued if needed. Aspirin is not typically added to the protocol for neuropathic pain management at this step. Methadone is reserved for severe pain and is not the standard choice at Step 2 of the WHO pain relief ladder for neuropathic pain.

Correct Answer: C

Rationale: In a client with a history of coronary artery disease (CAD) experiencing chest pain, the priority intervention for the nurse to implement first is to apply oxygen via nasal cannula. Oxygenation is crucial to ensure adequate oxygen supply to the tissues and the heart. This intervention takes precedence over administering sublingual nitroglycerin, obtaining an ECG, or initiating continuous cardiac monitoring. While these interventions are important, ensuring adequate oxygenation is the initial priority in the management of a client with chest pain.

Correct Answer: C

Rationale: To assess fever patterns accurately, the nurse should measure the client's temperature at regular intervals. This approach helps in identifying the pattern of fever spikes and fluctuations, which can provide valuable information for diagnostic and treatment purposes. Assessing for flushed, warm skin or documenting circadian rhythms may not directly reveal the fever pattern, while varying temperature measurement sites could lead to inconsistent readings. Therefore, measuring temperature at regular intervals is the most appropriate intervention to identify fever patterns in this scenario.

Correct Answer: D

Rationale: When a client begins to cough and gag during the insertion of a nasogastric tube, withdrawing the tube slightly and pausing is the appropriate action. This technique helps prevent further irritation, gives the client a moment to recover, and allows for a smoother continuation of the insertion process. Choice A is incorrect because allowing the client to rest without adjusting the tube position might not address the issue. Choice B is incorrect as removing the tube without addressing the cause of coughing and gagging may lead to repeated discomfort. Choice C is incorrect as continuing to insert the tube while the client is experiencing difficulties can increase discomfort and potential complications.

Correct Answer: B

Rationale: A nosebleed (B) in a client receiving heparin is a sign of heparin toxicity and requires immediate action. It indicates that the client is at risk of excessive bleeding. While a prolonged aPTT of 70 seconds (A) is worth monitoring, active bleeding takes precedence. Elevated blood pressure (C) and lightheadedness (D) are potential side effects of heparin but are not as urgently concerning as active bleeding.
