Correct Answer: C

Rationale: Correct! Dry mucous membranes are a common finding in clients with dehydration. Dehydration leads to reduced fluid volume in the body, resulting in dryness of mucous membranes, decreased skin turgor, and thirst. Bradycardia (slow heart rate) is not typically associated with dehydration, as the body tries to compensate for decreased fluid volume by increasing heart rate. Hypotension (low blood pressure) is a possible finding in dehydration due to reduced circulating volume. Tachypnea (rapid breathing) is more commonly seen in conditions like respiratory distress or metabolic acidosis, rather than dehydration.

Correct Answer: A

Rationale: The correct answer is to administer bronchodilators. In an acute asthma attack, the priority is to open the airways and improve airflow. Bronchodilators like albuterol are crucial in providing immediate relief to the patient. Monitoring oxygen saturation (choice B) is important but administering bronchodilators takes precedence in managing the acute attack. Providing supplemental oxygen (choice C) may be necessary but addressing the airway obstruction with bronchodilators is the priority. Starting IV fluids (choice D) is not the priority in an acute asthma attack unless specifically indicated for other reasons such as dehydration.

Correct Answer: C

Rationale: The correct intervention for a client with COPD is to teach pursed-lip breathing. This technique helps improve oxygenation and reduce dyspnea by promoting better air exchange in the lungs. Encouraging deep breaths may not be suitable for clients with COPD as it can lead to air trapping. Administering oxygen is important in COPD, but teaching pursed-lip breathing is a more direct intervention to help the client manage their condition. Limiting fluid intake is not a standard intervention for COPD and may not be relevant to improving respiratory status.

Correct Answer: A

Rationale: Administering oxygen is the best intervention for a patient experiencing respiratory distress because it helps improve oxygenation and alleviate respiratory distress. Oxygen therapy is crucial in ensuring that the patient receives an adequate supply of oxygen to meet the body's demands. Administering bronchodilators (Choice B) may be beneficial in specific respiratory conditions like asthma or COPD but may not be the primary intervention in all cases of respiratory distress. Administering IV fluids (Choice C) may be necessary in cases of dehydration or shock but would not directly address respiratory distress. Providing chest physiotherapy (Choice D) can help mobilize secretions in conditions like cystic fibrosis but is not the first-line intervention for respiratory distress.

Correct Answer: A

Rationale: The correct answer is A, Hypokalemia. Loop diuretics can lead to potassium loss, resulting in hypokalemia. This imbalance is a common concern because potassium plays a vital role in various physiological functions, including maintaining proper heart function. Choices B, C, and D are incorrect because loop diuretics typically do not cause hyperkalemia, hyponatremia, or hypercalcemia.
