foundations of nursing practice questions

Correct Answer: A

Rationale: The correct answer is A because an ultrasound-guided core biopsy is indeed faster, less expensive, and does not use radiation. - "Faster": Ultrasound-guided biopsies are typically quicker compared to stereotactic biopsies, as they are performed in real-time using ultrasound imaging. - "Less expensive": Ultrasound-guided biopsies are generally more cost-effective than stereotactic biopsies due to the equipment and resources required. - "Does not use radiation": Unlike stereotactic biopsies which involve the use of X-rays for guidance, ultrasound-guided biopsies do not expose the patient to radiation, making them safer in that aspect. The other choices are incorrect because they either inaccurately state that ultrasound-guided biopsies use radiation (C), take more time (D), or imply a slight increase in cost without highlighting the key advantages of speed and lack of radiation (B).

Correct Answer: B

Rationale: The correct answer is B because the patient's inability to count fingers indicates severe visual impairment. Testing hand motion perception is a more appropriate initial assessment for patients with such significant visual losses. This method can differentiate between light perception and no light perception, providing valuable information about the patient's visual acuity. The other choices are incorrect because assessing vision using a Snellen chart (A) requires more visual acuity than just being able to see hand motion. Performing a detailed examination of external eye structures (C) and palpating periocular regions (D) are not relevant for assessing visual acuity and do not provide information on the patient's ability to perceive hand motion.

Correct Answer: B

Rationale: The correct answer is B: Focusing the patient's immune system exclusively on the tumor. Biologic response modifiers (BRMs) work by enhancing the body's natural defenses to target and attack cancer cells specifically. This approach helps the immune system to recognize and destroy cancer cells while minimizing harm to normal cells. A: Promoting the synthesis and release of leukocytes - This is not the primary mechanism of action for BRMs. While leukocytes play a role in the immune response, BRMs target the immune system's response to tumors. C: Potentiating the effects of chemotherapeutic agents and radiation therapy - While some BRMs may be used in combination with these treatments, their primary mode of action is not to enhance the effects of chemotherapy or radiation therapy. D: Altering the immunologic relationship between the tumor and the patient - This choice is too broad and vague. BRMs specifically aim to direct the immune response towards targeting the tumor cells, rather than altering the overall immunologic relationship

Correct Answer: C

Rationale: The correct answer is C: Meaningful living during terminal illness is best supported in the home. This is because hospice care focuses on providing compassionate care and support in the comfort of the patient's own home, which can enhance quality of life and dignity. Being in a familiar and comfortable environment allows the patient to receive personalized care and emotional support from family members. Options A, B, and D are incorrect because hospice care emphasizes comfort and quality of life over technologic interventions, designated facilities, and prolonging physiologic dying. Ultimately, the goal of hospice care is to prioritize the patient's emotional and physical well-being during the end stages of life.

Correct Answer: B

Rationale: The correct answer is B: Nonverbal. The patient used nonverbal communication by pointing to the area of pain, which is a form of expressing information without words. This choice is correct because pointing is a nonverbal gesture that conveys a specific message. Verbal communication (A) involves spoken or written words, which were not used in this scenario. Intonation (C) refers to the rise and fall of the voice in speech, which was not demonstrated by the patient. Vocabulary (D) is the range of words known or used by a person, but the patient did not use words to communicate in this situation. In summary, the patient used nonverbal communication through pointing, making choice B the correct answer.
