A client with chronic obstructive pulmonary disease (COPD) presents with a respiratory rate of 32 breaths per minute and an oxygen saturation of 86%. What is the nurse's first action?

Correct Answer: A

Rationale: Administering oxygen at 2 L/min via nasal cannula is the nurse's first action when a client with COPD presents with a respiratory rate of 32 breaths per minute and an oxygen saturation of 86%. Oxygen therapy helps improve oxygen saturation in patients with COPD and respiratory distress. While notifying the healthcare provider is important, immediate intervention to improve oxygenation takes priority. Positioning the client in high Fowler's position can also assist with breathing but is not the initial action in this scenario. Suctioning the airway is not indicated unless there are secretions obstructing the airway, which is not mentioned in the scenario.

Correct Answer: B

Rationale: Administering prescribed IV antibiotics is the most crucial intervention in managing an infected foot ulcer in a client with diabetes mellitus. Antibiotics help combat the infection and prevent its spread systemically, which is vital in diabetic clients to prevent serious complications like sepsis. While obtaining a wound culture (Choice A) may provide valuable information for targeted antibiotic therapy, administering antibiotics promptly takes precedence to prevent the infection from worsening. Elevating the affected foot (Choice C) can help reduce swelling but is not as urgent as administering antibiotics. Consulting the wound care nurse (Choice D) may be beneficial for long-term wound management but does not address the immediate need to control the infection.

Correct Answer: B

Rationale: A distended abdomen with a firm, rigid feel is a concerning sign that suggests a complication such as bowel perforation, which requires immediate intervention. Absent bowel sounds can be expected in bowel obstructions but are not as urgent as a rigid abdomen. Frequent episodes of nausea and vomiting are common with bowel obstructions but do not indicate an immediate life-threatening complication. Hyperactive bowel sounds and abdominal cramping are more indicative of bowel obstruction rather than a complication requiring immediate attention.

Correct Answer: B

Rationale: The correct answer is B: Partial thromboplastin time (PTT). PTT is the lab value used to monitor the effectiveness of heparin therapy in clients with DVT. It measures the intrinsic pathway of coagulation and is prolonged by heparin therapy. Prothrombin time (PT) and International Normalized Ratio (INR) are primarily used to monitor warfarin therapy, not heparin. Checking hemoglobin and hematocrit levels is important but does not directly assess the effectiveness of heparin therapy in DVT.

Correct Answer: B

Rationale: The correct first action for a client with COPD experiencing increased shortness of breath and fatigue is to check the client's oxygen saturation. This assessment helps the nurse evaluate the client's respiratory status promptly. Administering a bronchodilator (Choice A) may be necessary but should come after assessing the oxygen saturation. Repositioning the client to a high Fowler's position (Choice C) can help improve breathing but should not precede oxygen saturation assessment. Administering oxygen via nasal cannula (Choice D) may be needed based on the oxygen saturation results, but assessing it first is crucial.
