A patient presents with fever, chills, headache, and myalgia after returning from a trip to sub-Saharan Africa. Laboratory tests reveal intraerythrocytic ring forms and trophozoites on blood smear examination. Which of the following is the most likely causative agent?

Correct Answer: A

Rationale: The most likely causative agent in this scenario is Plasmodium falciparum, a protozoan parasite that causes malaria. The patient's symptoms of fever, chills, headache, and myalgia align with the typical presentation of malaria. Additionally, the presence of intraerythrocytic ring forms and trophozoites on blood smear examination is characteristic of Plasmodium species, particularly P. falciparum, which causes the most severe form of malaria.

Correct Answer: D

Rationale: In a 55-year-old postmenopausal woman presenting with vaginal bleeding and a healthy cervix on examination, the most likely cause would be a cervical polyp. Cervical polyps are benign growths that can occur on the cervix and are often asymptomatic but can occasionally cause postmenopausal bleeding. Their appearance on examination would typically be a non-malignant finding with no cervical motion tenderness. Cervical cancer, endometrial cancer, and vaginal cancer would typically present with different examination findings and risk factors.

Correct Answer: B

Rationale: To keep abreast with the latest trends in peri-operative nursing, Merle should employ a combination of attending training and seminars, performing researches, and pursuing graduate studies. Attending training and seminars will expose Merle to new information, techniques, and best practices in peri-operative nursing. Performing researches will help Merle stay updated with current developments and evidence-based practices in the field. Pursuing graduate studies will provide Merle with advanced knowledge and skills, allowing for a deeper understanding of peri-operative nursing concepts and practices. By incorporating all of these strategies, Merle can ensure that he remains knowledgeable and competent in his role as a peri-operative nurse.

Correct Answer: C

Rationale: Placenta previa is a condition in pregnancy where the placenta implants low in the uterus, partially or completely covering the cervix. This can lead to painless, bright red vaginal bleeding in the third trimester. However, in some cases, placenta previa can also present with sudden onset of severe lower abdominal pain and signs of shock, such as syncope, pallor, and abdominal distention due to concealed bleeding. In severe cases, the bleeding can be significant and life-threatening for both the mother and the baby. It is important to promptly diagnose and manage placenta previa to prevent complications.

Correct Answer: A

Rationale: When a nurse involves well-being in her definition of health, it indicates a holistic approach that considers not only physical health but also emotional, mental, and social aspects of well-being. In the context of a family confronting the imminent death of a family member, the primary concern of the nurse would be to focus on reinforcing the need for the whole family to adapt to the impending death. This involves providing emotional support, facilitating communication, addressing coping mechanisms, and assisting the family in coming to terms with the situation. By emphasizing the importance of the whole family adapting to the imminent death, the nurse can help promote holistic well-being for the family during this challenging time.

Correct Answer: D

Rationale: Ella's feeling of joining Lory in heaven is best categorized as suicidal ideation. Suicidal ideation refers to thoughts or fantasies about dying, including thoughts of one's own death or thoughts of wanting to harm oneself. In this scenario, Ella is not explicitly expressing any immediate intent to harm herself or others, nor is she exhibiting paranoia or making a direct threat. Instead, her mention of joining Lory in heaven suggests that she is contemplating the idea of death, which falls under the category of suicidal ideation. It is essential to take such thoughts seriously and seek appropriate help and support for the individual experiencing them.

Correct Answer: A

Rationale: Estrogen exerts negative feedback on the hypothalamus by inhibiting the release of GnRH (Gonadotropin-Releasing Hormone). GnRH plays a crucial role in the regulation of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) production from the pituitary gland. By inhibiting the release of GnRH, estrogen ultimately leads to a decrease in FSH and LH levels. This process helps to suppress the maturation of the egg and ovulation, providing contraceptive effects.

Correct Answer: C

Rationale: Providing emotional support and addressing psychosocial needs demonstrates palliative care principles when caring for a patient experiencing end-of-life symptoms. Palliative care focuses on holistic care that encompasses physical, emotional, and spiritual support for patients and their families during times of serious illness. By addressing emotional needs and providing support, the nurse helps improve the patient's quality of life and comfort during this difficult time. This approach goes beyond just managing physical symptoms and pain, recognizing the importance of supporting the patient's overall well-being. Encouraging the patient to make decisions about life-sustaining treatments is also an important aspect of palliative care, but providing emotional support and addressing psychosocial needs is crucial in palliative care practice.

Correct Answer: B

Rationale: The best response for a nurse when a patient expresses dissatisfaction with the care they received during their hospital stay is to listen actively to the patient's concerns, apologize for any shortcomings, and offer to address the issues. It is crucial for healthcare providers to acknowledge the patient's perspective, validate their feelings, and work towards resolving any issues that may have contributed to their dissatisfaction. This approach demonstrates empathy, professionalism, and a commitment to patient-centered care, fostering trust and effective communication between the patient and the healthcare team. Dismissing the patient's concerns (option A), ignoring their dissatisfaction (option C), or telling them that their concerns are unfounded (option D) can further escalate the situation and lead to a breakdown in the patient-provider relationship.
