Correct Answer: B

Rationale: The correct answer is B. By asking the patient to demonstrate the instillation of medications, the nurse can directly assess the patient's ability to self-administer the medications safely and effectively. This method allows for a practical demonstration of skills, which is more reliable than relying solely on verbal descriptions or past experiences. Choices A, C, and D are incorrect because assessing for previous inability, describing the method, or evaluating functional status may not directly demonstrate the patient's competency in self-administering ocular medications.

Correct Answer: A

Rationale: The correct answer is A: Depression. In the context of the stages of death and dying proposed by Elisabeth Kübler-Ross, a patient exhibiting signs of loss, grief, and intense sadness is likely in the depression stage. This stage involves feelings of hopelessness, despair, and sorrow as the patient comes to terms with the reality of their situation. Denial (choice B) is characterized by a refusal to accept the diagnosis, anger (choice C) involves feelings of resentment and frustration, and resignation (choice D) signifies a sense of acceptance and peace. In this scenario, the patient's emotional state aligns most closely with depression, indicating a deep sense of sadness and mourning.

Correct Answer: A

Rationale: The correct answer is A: Wear a medical identification bracelet. This is important because in case of an emergency, such as an allergic reaction, medical professionals need to be aware of the child's severe food allergy quickly. The bracelet provides crucial information that can help in providing timely and appropriate medical care. B: Knowing how to use the antihistamine pen is also important in managing allergic reactions, but wearing a medical identification bracelet takes precedence as it provides immediate identification of the allergy. C: Knowing how to give injections of lidocaine is not relevant to managing a food allergy in a child. D: Avoiding live attenuated vaccinations may be necessary for individuals with certain allergies, but it is not directly related to educating parents about managing the child's food allergy.

Correct Answer: A

Rationale: The correct answer is A because spontaneous termination of a pregnancy is considered an abortion if it occurs before 20 weeks gestation. This is based on the medical definition of abortion as the termination of a pregnancy before the fetus is able to survive outside the womb. Choices B, C, and D are incorrect as they do not accurately reflect the criteria for defining abortion. B and D are specific conditions related to the fetus and the presence of infection, while C refers to passing products of conception intact, which can happen in both spontaneous and induced abortions.

Correct Answer: D

Rationale: The correct answer is D: According to current guidelines, breast conservation combined with radiation is as effective as a modified radical mastectomy. 1. Breast conservation surgery followed by radiation is a standard treatment option for early-stage breast cancer. 2. Studies have shown that breast conservation surgery combined with radiation therapy is equally effective in terms of long-term survival rates compared to mastectomy. 3. Current guidelines recommend considering breast conservation surgery as a viable option for patients with early-stage breast cancer. 4. Modified radical mastectomy is not necessarily needed to ensure complete removal of cancer, as breast conservation surgery followed by radiation can achieve the same goal. 5. Therefore, the nurse should reassure the patient's husband that the recommended treatment plan is based on current guidelines and is as effective as a modified radical mastectomy.
