Correct Answer: D

Rationale: The correct answer is D: 'This medication helps decrease swelling and mucus production.' Montelukast is used for long-term asthma management as it helps reduce inflammation and mucus production in the airways. It is not appropriate for acute asthma attacks. Choice A is incorrect because montelukast is not a rescue medication for acute attacks. Choice B is incorrect because montelukast is not specifically taken before exercise. Choice C is incorrect because montelukast is usually taken regularly, not just for a short duration.

Correct Answer: C

Rationale: 1 cm of water in the water seal chamber is insufficient to ensure proper functioning of the chest tube. The water seal chamber typically requires a water level of 2 cm. Tidaling with spontaneous respirations (choice A) is an expected finding indicating proper functioning. Having the drainage collection chamber 1/3 full (choice B) is within the normal range. A suction chamber pressure of -20 cm H2O (choice D) is an appropriate level for chest tube drainage.

Correct Answer: B

Rationale: The nurse should wear a dosimeter badge to monitor radiation exposure when caring for a client with a sealed radiation implant.

Correct Answer: B

Rationale: The correct answer is B. A PaCO2 level of 55 mm Hg is elevated, indicating carbon dioxide retention, a common complication of emphysema that necessitates intervention. Elevated PaCO2 can lead to respiratory acidosis, reflecting inadequate ventilation. Choices A, C, and D are within normal ranges. A PaO2 level of 89 mm Hg is acceptable. An HCO3 level of 25 mEq/L falls within the normal range, suggesting adequate compensation. A pH level of 7.37 is also within the normal range, indicating the client's acid-base balance is maintained.

Correct Answer: A

Rationale: The correct answer is A: "Hypnosis promotes increased control of pain perception during labor." Hypnosis can be effectively utilized during labor to help individuals enhance their control over how they perceive pain. Choice B is incorrect because hypnosis does not primarily use therapeutic touch to reduce anxiety. Choice C is incorrect as hypnosis is not primarily focused on biofeedback as a relaxation technique. Choice D is incorrect because hypnosis does not provide direct instructions to minimize pain but rather helps individuals gain control over their pain perception.
