Correct Answer: B

Rationale: Reporting medication discrepancies to the nurse manager is crucial to ensure patient safety and proper follow-up. The nurse manager is responsible for addressing medication errors and implementing necessary corrective actions. Choice A is incorrect because simply correcting the discrepancy without reporting it may lead to potential harm to the patient and violates professional standards. Choice C is incorrect as ignoring the discrepancy increases the risk of medication errors going unresolved. Choice D is incorrect because discussing the discrepancy with the client before verifying the accuracy of the record can cause confusion and compromise patient safety.

Correct Answer: D

Rationale: The nurse should see the patient with a hip replacement experiencing chest pain and dyspnea first because these symptoms could indicate a pulmonary embolism, which is a life-threatening condition requiring immediate attention. The other patients also need care, but urgent assessment and intervention are crucial in the case of potential pulmonary embolism to prevent serious complications or death.

Correct Answer: B

Rationale: Administering oxygen via nasal cannula as prescribed is the most appropriate action to improve the patient's oxygenation in COPD. Oxygen therapy helps maintain adequate oxygen levels in the blood, which is crucial for managing COPD. Encouraging the use of incentive spirometry, assisting with coughing and deep breathing exercises, and positioning the patient in high Fowler's position are all beneficial interventions, but administering oxygen is the priority for immediate oxygenation support in COPD.

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: B

Rationale: The correct answer is to assess the patient's oxygen saturation. In suspected pneumonia, ensuring adequate oxygenation is critical to monitor respiratory function. Auscultating lung sounds is important but assessing oxygen saturation takes precedence as it directly reflects the patient's oxygen levels. Monitoring white blood cell count is more related to infection assessment rather than immediate respiratory status. Checking skin integrity is essential for overall patient care but is not the priority in a patient with suspected pneumonia.
