Adult Health Nursing Answer Key

Correct Answer: B

Rationale: Entamoeba histolytica is a parasitic protist known to cause amoebiasis, a gastrointestinal infection that can lead to symptoms such as foul-smelling diarrhea containing cysts. Upon microscopic examination of the feces, the presence of Entamoeba histolytica cysts is a key diagnostic feature. This parasite can be transmitted through contaminated food or water, and individuals infected with Entamoeba histolytica may experience abdominal pain, bloody diarrhea, and weight loss. Proper diagnosis and treatment are essential to manage this infection and prevent complications.

Correct Answer: D

Rationale: Hurthle cell carcinoma is a subtype of thyroid cancer that arises from the follicular cells in the thyroid gland. Patients with Hurthle cell carcinoma may present with a painful thyroid nodule, which can be associated with signs of hypothyroidism due to the disruption of thyroid hormone production by the tumor. Fine-needle aspiration biopsy revealing Hurthle cells with nuclear features suggestive of malignancy is a characteristic finding in this type of carcinoma.

Correct Answer: B

Rationale: Spironolactone is a potassium-sparing diuretic commonly used in the management of heart failure. One of the significant side effects of spironolactone is hyperkalemia, which is an elevated level of potassium in the bloodstream. Spironolactone works by blocking the action of aldosterone, a hormone that regulates potassium and sodium balance in the body. By inhibiting aldosterone, spironolactone reduces potassium excretion in the urine, leading to potential accumulation of potassium in the body.

Correct Answer: D

Rationale: In a situation where a patient with terminal cancer is experiencing severe pain despite receiving analgesics, consulting with a pain management specialist is the most appropriate intervention. Pain management specialists have expertise in managing complex pain situations, especially in cases of terminal illness where pain control is crucial for improving quality of life. The specialist can review the current pain management plan, suggest alternative or adjunct therapies, adjust medication dosages, or explore different types of analgesics to optimize pain relief for the patient. Collaborating with a pain management specialist can help ensure the patient receives the most effective and personalized pain management approach tailored to their specific needs. Increasing the dose of analgesics, administering a different type of analgesic, or recommending non-pharmacological techniques may be appropriate interventions but should be guided by a specialist to ensure safe and effective pain management in a palliative care setting.

Correct Answer: B

Rationale: In the case of umbilical cord prolapse, the priority nursing action is to prepare for an immediate cesarean section. Umbilical cord prolapse is a serious obstetric emergency where the umbilical cord slips through the cervix ahead of the presenting part of the fetus. This can lead to compression of the cord, compromising fetal blood flow and oxygenation. Immediate delivery via cesarean section is necessary in order to prevent fetal hypoxia and avoid potential complications such as brain damage or death. Elevating the mother's hips or administering intravenous fluids rapidly may be interventions done in conjunction with preparing for a cesarean section, but the priority remains expedited delivery of the baby. Applying external fetal monitoring is not the most appropriate action in this emergency situation.
