Correct Answer: C

Rationale: In a client experiencing an acute asthma attack, decreased breath sounds suggest severe airway obstruction or respiratory fatigue, indicating a worsening condition. Loud wheezing, increased respiratory rate, and a productive cough are common manifestations during an asthma attack as the airways constrict, leading to turbulent airflow causing wheezing, increased effort to breathe resulting in a higher respiratory rate, and mucus production causing a productive cough. However, decreased breath sounds signify a critical situation requiring immediate intervention.

Correct Answer: D

Rationale: A decrease in the client's respiratory rate to 10 breaths per minute, while receiving oxygen therapy for COPD, is a concerning finding that may indicate carbon dioxide retention and respiratory depression. This situation requires immediate action to prevent further complications. An oxygen saturation of 90% is within an acceptable range for COPD patients on oxygen therapy. A respiratory rate of 22 breaths per minute and reports of shortness of breath are common in clients with COPD and may not necessitate immediate action unless accompanied by other concerning symptoms.

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.

Correct Answer: A

Rationale: The correct technique for suctioning a tracheostomy involves applying suction while withdrawing the catheter to avoid damaging the tracheal mucosa. Therefore, the student applying suction while inserting the catheter indicates a need for further teaching. Preoxygenating the client, suctioning up to three times if necessary, and limiting suctioning to 10 to 15 seconds each time are all appropriate actions in tracheostomy suctioning.

Correct Answer: A

Rationale: There is a drug-food interaction between statins and grapefruit that can lead to acute kidney failure. The client has elevated renal laboratory results, indicating kidney involvement. The nurse should ask if the client consumes grapefruit or grapefruit juice. While dehydration can elevate BUN, the increase in creatinine is more specific for kidney injury.
