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. Pale mucous membranes, such as those of the eyelids and lips, are a classic sign of anemia in infants. Anemia leads to decreased oxygen-carrying capacity, resulting in tissue hypoxia, which can manifest as pale mucosa. Choice A, a hemoglobin level of 12 g/dL, is within the normal range for a 10-month-old infant and would not necessarily indicate anemia. Choice C, hypoactivity, is a non-specific finding and can be present in various conditions, not specifically anemia. Choice D, a heart rate between 140 to 160, is within the normal range for an infant and is not a specific finding associated with anemia.

Correct Answer: B

Rationale: The correct answer is B: Teach tracheal suctioning techniques. Tracheal suctioning is crucial for maintaining a clear airway in clients with a tracheostomy. Without proper suctioning, secretions can accumulate and cause airway obstruction or respiratory infections. Educating the client on how to perform suctioning safely is a priority for discharge planning. Choices A, C, and D are important aspects of tracheostomy care, but teaching tracheal suctioning techniques takes precedence due to its direct impact on airway patency and preventing complications.

Correct Answer: C

Rationale: The correct teaching for a client with COPD prescribed home oxygen therapy is to educate them on how to clean and replace the oxygen tubing. This is crucial to prevent infections and ensure the effectiveness of the oxygen delivery system. Option A is not necessary as oxygen therapy is usually prescribed as needed, not continuously at night. While smoking cessation and avoiding smoke exposure are important in COPD management, it is not directly related to home oxygen therapy. Increasing fluid intake is beneficial for some conditions but is not specifically related to home oxygen therapy for COPD.

Correct Answer: B

Rationale: The correct answer is to assess the client's endotracheal tube for obstruction. When a client on mechanical ventilation experiences high-pressure alarms, the first action should be to check for any potential obstructions in the airway, which can trigger the alarms. Checking the oxygen saturation (Choice A) is important but not the priority when dealing with high-pressure alarms. Repositioning the client (Choice C) may be necessary later but should not be the initial action. Suctioning the client's airway (Choice D) should only be done after assessing for and addressing any obstructions in the endotracheal tube.
