Correct Answer: B

Rationale: The Heimlich maneuver is performed to clear the airway if a client is choking and cannot speak or breathe after swallowing food. Step 1: Assess the situation and confirm airway obstruction. Step 2: Stand behind the client, wrap your arms around their waist, and deliver upward abdominal thrusts. Step 3: Repeat thrusts until the object is dislodged. Other choices are incorrect as they do not address airway obstruction. A: Increasing medication absorption is not a purpose of the Heimlich maneuver. C: Preventing falls and D: Maintaining extremities in proper position are not related to choking emergencies.

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: 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: 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: D

Rationale: The correct answer is D: Turn off the antibiotic. This should be the nurse's first action because in an anaphylactic reaction, stopping the administration of the causative agent is crucial to prevent further harm. Continuing the antibiotic (Choice B) can worsen the reaction. Calling the doctor (Choice A) may cause a delay in the immediate intervention needed. Calling for help (Choice C) is important but turning off the antibiotic takes precedence to stop the allergen.
