Correct Answer: D

Rationale: The correct answer is D: �I will receive parenteral vitamin B12 therapy for the rest of my life.� This statement is correct because pernicious anemia is a lifelong condition requiring ongoing vitamin B12 supplementation. Patients with pernicious anemia lack intrinsic factor, which is needed to absorb vitamin B12 from food. Therefore, they need lifelong B12 therapy to prevent complications such as anemia and neurological damage. Choices A, B, and C are incorrect because they suggest a limited duration of therapy. Pernicious anemia is a chronic condition that necessitates continuous treatment. Choice A implies therapy until signs and symptoms disappear, which may not address the underlying cause of the deficiency. Choice B mentions therapy until vitamin B12 levels normalize, which may not prevent recurrence. Choice C suggests monthly therapy for a fixed period, which may not be sufficient for lifelong management.

Correct Answer: B

Rationale: The correct answer is B: Observe the patient for bleeding. Before a bone marrow biopsy, it is crucial to monitor the patient for bleeding tendencies as the procedure can cause bleeding. This step ensures early detection and prompt intervention if bleeding occurs. Explanation for other choices: A: Explaining the procedure to the family is important for informed consent but not the most crucial before the procedure. C: Administering an analgesic may be necessary for pain management but monitoring for bleeding takes precedence. D: Draping the biopsy site is important for maintaining a sterile field but does not directly impact patient safety like monitoring for bleeding.

Correct Answer: A

Rationale: The correct answer is A because a poultice of sodium bicarbonate and water can help neutralize the venom and reduce pain from wasp and bee bites. Sodium bicarbonate has alkaline properties that can counteract the acidic venom. Option B is incorrect as household ammonia can cause skin irritation and should not be applied to insect bites. Option C is incorrect because only option A is a safe and effective treatment for wasp and bee bites. Option D is incorrect as there is a suitable emergency treatment available.

Correct Answer: A

Rationale: The correct answer is A because stating feeling better after talking with family and friends demonstrates the use of healthy coping skills. This behavior indicates the patient is seeking and utilizing social support, which is crucial for managing stress and emotions effectively in diabetes management. Choices B, C, and D are incorrect because consuming high-carbohydrate foods when stressed can lead to poor blood sugar control, disliking support group meetings indicates avoidance of beneficial support resources, and spending most of the day in bed can contribute to physical and emotional deterioration, rather than effective coping.

Correct Answer: C

Rationale: Step-by-step rationale for choice C being correct: 1. Restlessness: Indicates increased work of breathing and hypoxia. 2. Suprasternal retractions: Sign of respiratory distress. 3. paO2 of 62: Indicates severe hypoxemia, common in ARDS. Summary: A: Enlarged heart on x-ray does not directly indicate ARDS. B: Thick green sputum suggests infection, not specific to ARDS. D: Wheezes and slow respirations are not typical of ARDS, and pCO2 is normal in ARDS.
