Correct Answer: D

Rationale: The correct answer is D: Different molecular structure in the cells. Malignant cells have alterations in their molecular structure, leading to uncontrolled growth and invasion of surrounding tissues, while benign cells retain their normal molecular structure and do not invade nearby tissues. This distinction is crucial in understanding why malignant cells are cancerous and pose a greater risk compared to benign cells. Other choices are incorrect because: A: Slow rate of mitosis of cancer cells - Malignant cells actually have a rapid rate of mitosis, contributing to their uncontrolled growth. B: Different proteins in the cell membrane - While there may be differences in proteins, the molecular structure is a more fundamental difference between malignant and benign cells. C: Differing size of the cells - Cell size alone is not a definitive characteristic that distinguishes between malignant and benign cells; molecular structure plays a more significant role.

Correct Answer: B

Rationale: The correct answer is B: Uses humility. Critical thinking in nursing involves being open-minded, self-aware, and willing to consider different perspectives. Humility allows nurses to acknowledge their limitations, seek feedback, and continuously learn and improve. Instilling faith (A) may be important but does not directly relate to critical thinking standards. Self-confidence (C) can be beneficial, but excessive confidence can lead to closed-mindedness. Supportiveness (D) is valuable in patient care but does not specifically demonstrate critical thinking standards. In summary, humility enables nurses to approach patient communication with an open and reflective mindset, essential for applying critical thinking standards effectively.

Correct Answer: B

Rationale: The correct answer is B: Pink. In a healthy ear, the tympanic membrane should appear pink due to the rich blood supply. This color indicates good vascularization and normal functioning of the ear. Yellowish-white (choice A), gray (choice C), and bluish-white (choice D) are incorrect because they do not reflect the normal color of a healthy tympanic membrane. Yellowish-white may indicate fluid behind the eardrum, gray may suggest infection or inflammation, and bluish-white could indicate poor blood flow or trauma. Therefore, the pink color of the tympanic membrane is the most appropriate and indicative of a healthy ear in this case.

Correct Answer: B

Rationale: Correct Answer: B Rationale: 1. Prone position post retinal detachment repair helps the gas bubble or silicone oil stay against the retina to support healing. 2. This position prevents the bubble/oil from moving and causing further detachment. 3. Repositioning can jeopardize the surgical repair and lead to complications. 4. Calling the physician (A) is unnecessary as the order is clear. 5. Instructing the patient to prevent bleeding (C) is not related to the positioning after retinal detachment repair. 6. Repositioning after the first dressing change (D) contradicts the initial order and risks complications.

Correct Answer: A

Rationale: The correct answer is A because hospice care is centered on a holistic approach that considers the physical, emotional, social, and spiritual needs of both the patient and their family. This principle recognizes that caring for a terminally ill patient involves supporting the entire family unit. Choice B is incorrect because family support is integral to hospice care. Choice C is incorrect because hospice care extends beyond just the patient to include their loved ones. Choice D is incorrect because the care team should address all aspects of care for both the patient and their family, not prioritize one over the other.
