Correct Answer: D

Rationale: The correct answer is D: Tuberculosis. Coughing up blood (hemoptysis) is a key symptom of tuberculosis. Tuberculosis is a respiratory infection caused by the bacterium Mycobacterium tuberculosis. The other options are incorrect because an allergic reaction typically involves symptoms like itching, hives, or swelling, not coughing up blood. Ringworm is a fungal skin infection characterized by a red, circular rash, and systemic lupus erythematosus is an autoimmune disease that primarily affects joints and skin without causing hemoptysis.

Correct Answer: A

Rationale: Choice A is the correct answer as nightmares about upcoming surgery indicate psychological distress commonly associated with fears, anxiety, and stress related to the treatment. Choices B, C, and D suggest positive emotions and proactive behaviors that are not typical signs of psychological distress in this context. Feeling more energetic, making future plans, and looking forward to treatment are generally positive indicators of coping and adjustment to the situation.

Correct Answer: A

Rationale: The correct answer is A. Regulating oxygen flow at no more than 6 L/min via nasal cannula is a safe practice to prevent potential complications such as oxygen toxicity. Option B suggesting administering oxygen at a higher flow rate for better saturation is incorrect as it can lead to adverse effects. Option C is incorrect because using a high-flow nasal cannula for all clients is not necessary and should be based on individual client needs. Option D is incorrect as adjusting oxygen flow solely based on client comfort without considering the prescribed flow rate can compromise the effectiveness of oxygen therapy.

Correct Answer: B

Rationale: The best nursing action in response to a terminally ill client stating their agnostic beliefs is to document the client's spiritual assessment. By documenting this information, the healthcare team can ensure that the client's beliefs are acknowledged and respected in their care plan. Providing information about the chapel's hours or inviting the client to a healing service may not align with the client's beliefs and preferences. Offering to contact a spiritual advisor of the client's choice may not be necessary if the client has clearly stated their agnostic beliefs, as they may not wish to engage in spiritual counseling.

Correct Answer: C

Rationale: Ensuring the water seal chamber is filled to the appropriate level is crucial to maintain the effectiveness of the chest tube drainage system. This step helps prevent air from entering the pleural space, ensuring proper lung re-expansion. 'Milking' the chest tube is not recommended as it can cause damage to the chest tube and surrounding tissues. Clamping the chest tube is not advisable as it can lead to tension pneumothorax. Securing the chest tube to the bed is important for stability but does not directly impact the functioning of the chest tube.
