Mark, a 7-year-old client is brought to the emergency department. He's tachypneic and afebrile and has a respiratory rate of 36 breaths/minute and has a nonproductive cough. He recently had a cold. Form this history; the client may have which of the following conditions?

Correct Answer: A

Rationale: The correct answer is A: Acute asthma. The client's presentation of tachypnea, nonproductive cough, and recent cold is suggestive of an acute asthma exacerbation. Asthma commonly presents with these symptoms, especially in children. The absence of fever and productive cough makes bronchial pneumonia less likely. COPD and emphysema are typically seen in older individuals with a history of smoking, not in a 7-year-old child. Therefore, based on the client's age, symptoms, and absence of other risk factors, acute asthma is the most likely diagnosis.

Correct Answer: B

Rationale: The correct answer is B: Kinked or obstructed chest tube. When a client with a pneumothorax develops hypotension, neck vein distention, tracheal shift, absent breath sounds, and diaphoresis, it indicates a tension pneumothorax. In this case, the chest tube may be kinked or obstructed, leading to a buildup of pressure in the pleural space. This increased pressure causes a shift in the mediastinum and impairs venous return, resulting in hypotension and other signs of tension pneumothorax. Checking for a kinked or obstructed chest tube is crucial to relieve the pressure and prevent further complications. Other choices are incorrect: A: Infection of the lung does not typically lead to the rapid onset of symptoms seen in tension pneumothorax. C: Excessive water in the water-seal chamber would not cause the described signs of tension pneumothorax. D: Ex

Correct Answer: A

Rationale: Correct Answer: A Rationale: A: The patient is under general anesthesia during bone marrow transplantation to ensure no discomfort or movement during the procedure, which involves inserting a needle into the bone. B: Aspirated bone marrow is mixed with anticoagulants like heparin to prevent clotting and ensure the cells remain viable. C: The iliac crest is a common site for bone marrow aspiration due to its accessibility and abundance of marrow-producing cells. D: The recipient receives preparatory chemotherapy like cyclophosphamide to suppress the immune system and reduce the risk of rejection during transplantation.

Correct Answer: B

Rationale: The correct answer is B: Carcinoma in situ, no abnormal regional lymph nodes, and no evidence of distant metastasis. 1. TIS indicates carcinoma in situ, meaning abnormal cells are present but have not invaded nearby tissues. 2. N0 indicates no abnormal regional lymph nodes, suggesting no spread of cancer to the lymph nodes. 3. M0 indicates no evidence of distant metastasis, indicating the cancer has not spread to other parts of the body. Therefore, the classification TIS, N0, M0 signifies that the lesion is in the early stage, confined to its original location without lymph node involvement or distant spread. Incorrect choices: A: Incorrect - TIS indicates carcinoma in situ, not no evidence of primary tumor. C: Incorrect - The TNM classification is clear, not "Can't assess tumor or regional lymph nodes." D: Incorrect - TIS does not indicate ascending degrees of distant metastasis, and N0 indicates no abnormal lymph nodes, not "

Correct Answer: D

Rationale: Correct Answer: D (The client wears a watch and wedding band) Rationale: 1. MRI machines use strong magnetic fields, which can interact with metal objects like a watch and wedding band, causing them to move or heat up. 2. Movement of metal objects can lead to injury to the client or interfere with the imaging process. 3. It is essential for the client to remove all metal objects before entering the MRI room to ensure safety and accurate imaging. Summary: A: The client lying still is important for a successful MRI scan and does not pose a threat. B: Client asking questions does not pose a threat, as communication is normal during the procedure. C: Hearing thumping sounds is a common experience during an MRI scan and does not pose a direct threat to the client.
