Correct Answer: A

Rationale: The priority action for a client with an oxygen saturation of 88% on room air is to initiate oxygen therapy to improve oxygen saturation levels. Oxygen therapy is crucial to address hypoxemia promptly. Placing the client in a high-Fowler's position can also aid in oxygenation, but administering oxygen takes precedence. While notifying the healthcare provider is important, it is a secondary action after ensuring the client's immediate need for oxygen is met. Documenting the finding in the client's medical record is necessary for continuity of care but is not the primary intervention when addressing hypoxemia.

Correct Answer: A

Rationale: The correct answer is A. Effective oxygen therapy should improve the client's ability to perform activities without dyspnea. This indicates that the oxygen therapy is adequately supporting the client's respiratory needs. An oxygen saturation of 92% may suggest the need for a higher flow rate to improve oxygenation. A respiratory rate of 24 breaths per minute is elevated, indicating potential respiratory distress. A productive cough does not necessarily indicate effective oxygen therapy, as it is a symptom of respiratory irritation or infection, not oxygenation status.

Correct Answer: B

Rationale: The client joining a book club that meets outside the home and requires him or her to go out in public is the best indicator that goals for Impaired Self-Esteem are being met. This social activity indicates an improvement in self-confidence and willingness to engage with others, which are essential aspects of self-esteem. The other choices, while positive, do not directly address self-esteem concerns related to social interaction and confidence.

Correct Answer: A

Rationale: In COPD, the client often develops a barrel chest, characterized by an increased anterior-posterior diameter of the chest. This change is due to air trapping and hyperinflation of the lungs. Decreased respiratory rate, weight gain, and productive cough with yellow sputum are not typically associated with COPD. Weight loss is more common due to increased work of breathing and decreased energy expenditure in individuals with COPD.

Correct Answer: A

Rationale: When a client is prescribed nicotine replacement therapy, it is crucial to emphasize that smoking while using this therapy can increase the risk of a stroke. Smoking while on nicotine replacement therapy can lead to excessive nicotine levels in the body, elevating cardiovascular risks. Therefore, the nurse should educate the client on the importance of avoiding smoking while utilizing this medication. Choices B, C, and D are not relevant to the specific teaching required for a client on nicotine replacement therapy.
