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: D

Rationale: The correct answer is D because clients taking spironolactone should have their potassium levels checked regularly. Spironolactone is a potassium-sparing diuretic, meaning it helps the body retain potassium and can lead to hyperkalemia if levels become too high. Choices A, B, and C are incorrect because avoiding foods high in potassium, sodium, or monitoring blood pressure are not specific to the teaching related to spironolactone.

Correct Answer: A

Rationale: The correct instruction for using a peak flow meter is to place the mouthpiece in your mouth and blow out as quickly as you can. This action helps measure the peak expiratory flow of the client. Choice B is incorrect because exhaling slowly does not provide an accurate peak flow reading. Choice C is incorrect as taking a slow deep breath before blowing interferes with obtaining an accurate measurement. Choice D is incorrect as blowing at a steady rate for 3 seconds may not reflect the peak expiratory flow accurately.

Correct Answer: A

Rationale: A potassium level of 5.0 mEq/L is at the upper limit of normal and should be monitored closely in clients taking spironolactone, which is potassium-sparing. Elevated potassium levels can lead to hyperkalemia, especially in individuals on potassium-sparing diuretics like spironolactone. Monitoring and reporting high potassium levels are crucial to prevent potential complications such as cardiac arrhythmias. Blood pressure (choice B), sodium level (choice C), and calcium level (choice D) are not directly related to the use of spironolactone and do not require immediate reporting in this scenario.

Correct Answer: B

Rationale: The correct answer is B. An FHR baseline of 170/min is considered tachycardia, which is above the normal range during labor and requires immediate attention. High FHR can indicate fetal distress or maternal fever. Choice A, contractions lasting 80 seconds, are within normal range for active labor. Choice C, early decelerations in the FHR, are usually benign and do not typically require immediate intervention. Choice D, a temperature of 37.4°C (99.3°F), is within normal limits.
