Correct Answer: C

Rationale: The correct answer is to check the oxygen level regularly using a pulse oximeter. This instruction is crucial as it ensures safe and adequate oxygenation for the client. Option A is incorrect as oxygen should not be stored in a storage room but in a well-ventilated area. Option B is not ideal as oxygen should be left on unless otherwise specified by a healthcare provider. Option D is also important but not directly related to the primary instruction of monitoring oxygen levels.

Correct Answer: B

Rationale: The correct answer is B because a baseline FHR of 170/min indicates fetal tachycardia, which needs further evaluation. Choice A about contractions lasting 80 seconds is within the normal range for active labor. Choice C, early decelerations in the FHR, are generally considered benign and do not require immediate reporting. Choice D, a temperature of 37.4°C (99.3°F), falls within normal limits for a laboring client and does not warrant immediate reporting.

Correct Answer: A

Rationale: The correct answer is A: 'There is no fluctuation in the water seal chamber.' In a client with a pneumothorax being treated with a chest tube, the absence of fluctuation in the water seal chamber indicates that the lung has re-expanded. This finding suggests that there is no air leak from the lung into the pleural space. Choices B and C are incorrect because continuous bubbling in the suction control chamber or tidaling in the water seal chamber would suggest ongoing air leakage, indicating that the lung has not fully re-expanded. Choice D is also incorrect as the position of the drainage system does not directly indicate lung re-expansion.

Correct Answer: B

Rationale: The correct answer is B because prednisone is usually prescribed for long-term use. Stopping it abruptly can lead to adrenal insufficiency. Choice A is incorrect because prednisone should be taken with food to prevent stomach upset. Choice C is incorrect as prednisone is typically tapered off gradually to avoid adverse effects. Choice D is incorrect as there is no specific requirement to take prednisone with a high-protein snack.

Correct Answer: C

Rationale: The correct answer is C: Diaphoresis. Diaphoresis, which is excessive sweating, is a common response to acute pain due to increased sympathetic nervous system activity. Options A and B, Bradycardia and Hypotension, are unlikely findings in a client experiencing acute pain as pain usually triggers an increase in heart rate (tachycardia) and blood pressure. Option D, Hyperactive bowel sounds, is not typically associated with acute pain.
