Correct Answer: C

Rationale: The correct answer is C: administer oxygen via face mask. Given Aling Nena's sudden chest heaviness post-surgery, oxygen administration is the priority to ensure adequate oxygenation. This can help rule out potential respiratory issues or hypoxemia, which are common post-operatively. Providing oxygen promptly can prevent further complications such as respiratory distress or cardiac compromise. Documenting the pain characteristics (choice A) can be done after ensuring immediate physiological needs are met. Offering analgesics (choice B) without confirming the underlying cause can mask symptoms and delay appropriate interventions. Informing the physician (choice D) is important but not as urgent as addressing potential respiratory compromise.

Correct Answer: C

Rationale: The correct answer is C: Amount and color of sinus drainage. Assessing the amount and color of sinus drainage is crucial in evaluating the effectiveness of nursing interventions for sinusitis discomfort as it indicates the presence of infection or inflammation. Changes in color or amount can signify improvement or worsening of the condition. WBC count (A) may indicate infection but doesn't directly reflect sinusitis discomfort. Capillary refill (B) assesses circulation, not sinusitis. Comfort level (D) is subjective and can vary among individuals, making it less reliable for assessing the effectiveness of interventions.

Correct Answer: A

Rationale: The correct answer is A: Assessment. In the scenario, the nurse failed to assess the patient's condition promptly after the patient complained of feeling dizzy and light-headed. Assessment is the first phase of the nursing process and involves collecting data to identify the patient's health status. By not reassessing the patient's vital signs and symptoms, the nurse missed an opportunity to detect the worsening condition. The other choices are incorrect because the error occurred before diagnosis (B), implementation (C), and evaluation (D) phases. In diagnosis, the nurse identifies the patient's problems; in implementation, the nurse carries out the care plan; and in evaluation, the nurse assesses the effectiveness of interventions.

Correct Answer: C

Rationale: Step 1: Most clients are not hospitalized long after a mastectomy - Correct. This is because mastectomy is often performed as an outpatient procedure, and clients are discharged home shortly after surgery. Step 2: The adverse effects of mastectomy are not immediate - Incorrect. Adverse effects may occur post-surgery, but early discharge is not solely due to immediate adverse effects. Step 3: The wound of the surgery is not highly contagious - Incorrect. Mastectomy wounds are not contagious, and isolation precautions are not necessary. Step 4: Suicidal tendencies in women undergoing mastectomy are not high - Incorrect. While emotional support is crucial, early discharge is not primarily due to suicidal tendencies. Summary: Choice C is correct because mastectomy clients are typically not hospitalized long, making early discharge instructions and home care arrangements necessary. Choices A, B, and D are incorrect as they do not directly relate to the primary reason for early discharge and home care planning.

Correct Answer: C

Rationale: Upon arrival, checking the lungs for equal breath sounds bilaterally is the first action. This is crucial to assess airway patency and breathing effectiveness in a patient with a history of diving accident and intubation. Ensuring proper oxygenation takes precedence over other actions. Taking vital signs, inserting an IV line, and performing a neurologic check can wait until airway and breathing are adequately assessed.
