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: In the grading system used for edema, +1 indicates no visible edema in the leg, +2 indicates slight edema with indentations that quickly resolve, +3 indicates moderate edema with deeper indentations that may take longer to resolve, and +4 indicates severe edema with very swollen legs. In this case, since the edema is described as slightly swollen, the appropriate grade to document would be +2.

Correct Answer: C

Rationale: The nurse explains to the mother that the uterus will return to its pre-pregnancy state in about four to six weeks after giving birth. This timeframe is an average estimation of how long it takes for the uterus to shrink back to its normal size and position after going through the process of supporting and nourishing a developing fetus. The process of the uterus returning to its pre-pregnancy state is known as involution, where the uterus undergoes contractions to shed the excess lining and reduce in size. This period is crucial for the body to heal and recover from the changes that occurred during pregnancy and childbirth.

Correct Answer: C

Rationale: The nurse's priority action when noticing a malfunctioning anesthesia machine in the operating room should be to inform the anesthesia provider immediately. Anesthesia providers are responsible for administering anesthesia safely during surgical procedures, and they need to be made aware of any equipment issues promptly to ensure patient safety. Continuing with the surgical procedure using a malfunctioning anesthesia machine can pose serious risks to the patient's well-being. Using an alternative anesthesia machine may be an option, but informing the anesthesia provider first ensures that the appropriate action is taken to address the issue effectively. Documenting the malfunction in the equipment log is important for record-keeping purposes, but it should not take precedence over informing the anesthesia provider and taking immediate action to address the problem.

Correct Answer: A

Rationale: Confidentiality is the ethical principle that requires healthcare providers to keep client information private and not disclose it without the client's consent. When client information is shared beyond the interdisciplinary team without the client's consent, it breaches the trust and privacy expected in the nurse-client relationship. This breach not only violates the ethical principle of confidentiality but also undermines the client's autonomy and right to control their own personal information. Maintaining confidentiality is crucial for building trust and ensuring the well-being of the client.
