Correct Answer: B

Rationale: In this situation, the nurse needs to obtain a telephone order because the patient's condition has changed significantly. The drop in blood pressure from 120/80 to 90/50 along with the saturated incision dressing indicates a potential complication or need for immediate intervention. The nurse must act quickly to address the situation and may require additional orders from the primary care provider over the phone to manage the patient's condition effectively. The urgency and critical nature of the situation necessitate obtaining a telephone order promptly to ensure the best outcome for the patient.

Correct Answer: A

Rationale: The correct instruction for the nurse to provide to the patient is that the patient should discuss this new herbal remedy with her ophthalmologist promptly. This is essential because herbal remedies can interact with prescription medications or affect the patient's eye condition. The ophthalmologist can provide guidance on the safety and effectiveness of the herbal remedy in relation to the patient's glaucoma treatment plan. It is crucial for healthcare providers to be aware of all treatments the patient is receiving to ensure coordinated and optimal care.

Correct Answer: A

Rationale: The patient may be trying to protect loved ones from the emotional effects of the illness. This behavior could be a form of denial, a defense mechanism where the individual refuses to acknowledge the reality of the diagnosis in order to shield their loved ones from distress. By rejecting the diagnosis and refusing treatment, the patient may believe that they are preventing their family and friends from experiencing the emotional pain associated with the illness. This behavior is a common coping mechanism in response to overwhelming and distressing news like a terminal illness diagnosis. It serves a psychosocial purpose of trying to protect others from suffering, even though it may not align with the patient's best interest in terms of receiving appropriate medical care.

Correct Answer: B

Rationale: A person who has a history of high-risk behaviors, such as drug use, should be retested for hepatitis B during the third trimester. This is because the virus can have a long incubation period before showing up in blood tests. Retesting in the third trimester ensures that if the infection was acquired after the initial screening, it will be detected in time to provide appropriate care and interventions. Retesting is important in high-risk individuals to ensure proper management and prevention of hepatitis B transmission.

Correct Answer: A

Rationale: Mottling of the lower limbs is a common physical sign seen in patients approaching death. This occurs when there is poor circulation leading to a bluish or purplish discoloration of the skin, particularly on the extremities. The appearance of mottling indicates that the body is no longer able to maintain adequate blood flow to the extremities, signaling that the patient is in the final stages of life. It is a significant finding that strongly suggests imminent death in patients with terminal illness, such as in this case of a patient with terminal lung cancer who is unconscious.
