Correct Answer: D

Rationale: Confusion is a potential adverse effect of digoxin therapy. Digoxin toxicity can manifest as various central nervous system symptoms, including confusion, delirium, and disorientation. It is important to monitor for signs of digoxin toxicity in patients taking this medication, especially those with a history of heart failure or renal impairment. Other common signs of digoxin toxicity may include visual disturbances (like halos around lights), gastrointestinal symptoms (like nausea and vomiting), and cardiac arrhythmias. Monitoring serum digoxin levels can help guide therapy and identify toxicity early.

Correct Answer: D

Rationale: The presentation of a small, painless, well-defined nodule on the lateral aspect of the neck, above the clavicle, along with the cytology showing clusters of polygonal cells with abundant granular cytoplasm is most indicative of a parathyroid adenoma. Parathyroid adenomas are benign tumors derived from the parathyroid gland that can produce excess parathyroid hormone (PTH), leading to hyperparathyroidism. The characteristic histology of parathyroid adenomas includes chief cells with abundant granular cytoplasm.

Correct Answer: C

Rationale: A physical therapist would be the best member of the multidisciplinary team to collaborate with when a patient can benefit from using a leg prosthesis. Physical therapists specialize in assessing and treating movement disorders, including those related to amputation and prosthetic use. They can help the patient improve their mobility, strength, balance, and overall functional abilities with the prosthesis. Physical therapists can provide training on how to use the prosthesis effectively, reduce the risk of falls, and optimize the patient's independence and quality of life. Collaborating with a physical therapist ensures that the patient receives comprehensive care tailored to their specific needs and goals related to using a leg prosthesis.

Correct Answer: A

Rationale: A nurse can be charged with negligence when they give the patient the wrong medication. Negligence in healthcare typically refers to a situation where a healthcare provider fails to provide a standard level of care, resulting in harm to the patient. Giving the wrong medication can lead to serious consequences for the patient, including adverse reactions, worsening of the condition, or even death. It is a clear violation of the duty of care that a nurse owes to their patients, and such a mistake can have legal and professional repercussions for the nurse.

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.
