A nurse in a medical unit is caring for a client with heart failure. The client suddenly develops extreme dyspnea,tachycardia and lung crackles. The nurse immediately asks another nurse to contact the primary health care provider and prepares to implement ALL priority interventions EXCEPT?

Correct Answer: C

Rationale: Rationale: Option C, transporting the client to the coronary care unit, is not the priority intervention because the client is presenting with acute pulmonary edema, a sign of worsening heart failure. Administering oxygen (Option A) is crucial to improve oxygenation. Administering furosemide (Option B) helps reduce fluid overload. Obtaining a stat Hepatic Panel (Option D) may be necessary to assess liver function due to medication side effects. However, immediate actions to address respiratory distress and tachycardia take precedence over moving the client to another unit.

Correct Answer: C

Rationale: The correct answer is C (80 mmHg) because the partial pressure of oxygen in the air is directly proportional to the percentage of oxygen in the air. In the atmosphere, oxygen makes up approximately 21% of the air. Therefore, to calculate the partial pressure of oxygen, you would multiply the total barometric pressure by the percentage of oxygen (0.21). So, 447 mmHg x 0.21 = 94.07 mmHg. This is the partial pressure of oxygen at sea level. To find the partial pressure of oxygen at a higher altitude, you would consider the decrease in total barometric pressure. At 447 mmHg, the partial pressure of oxygen would be around 80 mmHg. Summary: A: Incorrect because it is too low. B: Incorrect because it is too low. D: Incorrect because it is too high.

Correct Answer: B

Rationale: The correct answer is B. Applying a dressing over the wound and taping it on three sides should be done first to prevent air from entering the wound and causing a tension pneumothorax. This action helps stabilize the wound and minimizes the risk of further complications. Drawing blood for hematocrit and hemoglobin (A) is not the priority in this situation. Chest tube insertion (C) and starting an IV line (D) can be necessary interventions but are not the immediate priority in managing a sucking chest wound.

Correct Answer: C

Rationale: The correct answer is C: Use diaphragmatic breathing. Diaphragmatic breathing involves using the diaphragm to breathe deeply, allowing more air to enter the lungs and improving oxygenation. This is beneficial for clients with chronic bronchitis as it helps improve lung function and efficiency. Making inhalation longer than exhalation (Choice A) may lead to hyperventilation. Exhaling through an open mouth (Choice B) can lead to loss of carbon dioxide. Using chest breathing (Choice D) is less efficient and can exacerbate breathing difficulties in clients with chronic bronchitis. Diaphragmatic breathing is the most effective technique for improving breathing and should be emphasized in teaching.

Correct Answer: A

Rationale: The correct answer is A. A client with suspected tuberculosis is likely to experience fatigue, weight loss, low-grade fevers, and night sweats due to the chronic infection affecting the body. Fatigue and weight loss are common symptoms of active tuberculosis due to the systemic impact of the infection. Low-grade fevers and night sweats are characteristic of tuberculosis due to the body's immune response. These symptoms are key indicators of tuberculosis infection. Choices B, C, and D are incorrect because they describe symptoms that are not typically associated with tuberculosis. Dyspnea, chest pain, and cough (Choice B) are more commonly seen in respiratory conditions such as pneumonia or bronchitis. Rapid shallow breathing, prolonged labored expiration, and stridor (Choice C) are indicative of airway obstruction rather than tuberculosis. Dyspnea, hypoxemia, and decreased pulmonary compliance (Choice D) are more characteristic of conditions such as chronic obstructive pulmonary disease (COPD) rather than tuberculosis.
