A patient presents with a thyroid nodule and signs of hyperthyroidism. Fine-needle aspiration biopsy reveals Hurthle cells and cellular atypia. Which endocrine disorder is most likely responsible for these symptoms?

Correct Answer: C

Rationale: Hurthle cell carcinoma is a type of thyroid cancer that arises from the Hurthle cells of the thyroid gland. Patients with Hurthle cell carcinoma may present with a thyroid nodule and signs of hyperthyroidism, which can mimic other thyroid disorders such as Graves' disease. Fine-needle aspiration biopsy revealing Hurthle cells and cellular atypia is suggestive of a Hurthle cell neoplasm, particularly Hurthle cell carcinoma. It is important to differentiate Hurthle cell carcinoma from benign Hurthle cell adenomas or other thyroid conditions to guide appropriate management and treatment.

Correct Answer: B

Rationale: Becoming emotional is an example of a barrier to successful negotiation because emotions can cloud judgment, lead to irrational decision-making, and hinder effective communication. When negotiating, it is important to remain calm, composed, and rational to navigate the discussion effectively. Emotions can derail the negotiation process, making it challenging to find common ground and reach a mutually beneficial agreement.

Correct Answer: A

Rationale: The healthcare team should prioritize administering lactulose or other ammonia-lowering agents to manage hepatic encephalopathy in a patient with acute liver failure. Hepatic encephalopathy is a neuropsychiatric syndrome that occurs in patients with liver dysfunction, leading to the accumulation of ammonia and other neurotoxic metabolites in the bloodstream. Lactulose works by acidifying the colon, which promotes the conversion of ammonia to ammonium, a less toxic form that can be excreted in the stool. By reducing the levels of ammonia, lactulose helps improve the neurological symptoms associated with hepatic encephalopathy.

Correct Answer: B

Rationale: The first step in the qualitative research process is typically conducting a review of existing literature on the topic of interest. This involves exploring existing research studies, theories, and findings related to the area being studied. By reviewing the literature, researchers can gain a better understanding of the current knowledge and identify gaps in the existing research that their study can address. This step helps researchers define the research question, refine the study design, and establish a strong theoretical framework for the study.

Correct Answer: A

Rationale: When collecting evidence from a rape victim, it is important to handle the victim's clothing properly to preserve any potential evidence. The preferred method is to remove the clothing and place them in a paper bag. Paper bags are used in order to prevent the alteration or degradation of any DNA evidence that may be present on the clothing. Paper bags allow the clothing to breathe and prevent the growth of mold or other contaminants that can occur in plastic bags or trash bags. Additionally, paper bags help preserve trace evidence such as fibers or hairs that may be crucial in the investigation of the case. It is essential to handle and store the clothing correctly to maintain the integrity of the evidence for the investigation and potential prosecution.

Correct Answer: C

Rationale: Methotrexate is a medication commonly used in the treatment of rheumatoid arthritis. It is known to have potential hepatotoxic effects, meaning it can harm the liver. Monitoring liver function tests (such as alanine aminotransferase (ALT), aspartate aminotransferase (AST), and bilirubin levels) is essential to detect any liver damage early on during methotrexate therapy. By closely monitoring liver function tests, healthcare providers can assess the medication's impact on the liver and determine if any dose adjustments or discontinuation of the drug is necessary to prevent further liver damage. Regular monitoring of liver function tests helps ensure the safe and effective use of methotrexate in patients with rheumatoid arthritis.

Correct Answer: D

Rationale: COPD (Chronic Obstructive Pulmonary Disease) patients often struggle with breathing difficulties due to their conditions, hence it is important for them to conserve their energy as much as possible. Standing while performing activities like shaving or combing hair can be physically demanding for COPD patients as it requires more energy and can lead to increased shortness of breath. It is recommended for COPD patients to sit down or assume a supported position (like the tripod position with elbows supported on a table) to reduce the energy expended and minimize the strain on their respiratory system. Standing in front of the mirror while performing grooming activities is a task that can be easily modified to a seated position, thus conserving energy and reducing the risk of exacerbating breathing difficulties for COPD patients.

Correct Answer: D

Rationale: It is NOT recommended to use the same syringe and needle in administering two different vaccines. This is to prevent contamination or mixing of different vaccines, which could potentially affect their effectiveness or pose a risk to the individual receiving the vaccines. It is important to use separate syringes and needles for each vaccine to ensure proper administration and prevent any adverse reactions.
