Correct Answer: B

Rationale: The correct process for taking a telephone order from a provider involves reading back the information for accuracy. This step ensures that the order is correctly understood and reduces the risk of errors. While listing patient information (Choice A) is essential, it does not encompass the complete process of verifying the order. Having a witness listen to the order (Choice C) may not always be practical or necessary, as direct verification is more efficient. Writing down the order and following up (Choice D) is not as crucial as the immediate read-back process, which allows for real-time clarification and confirmation.

Correct Answer: A

Rationale: A below-the-knee amputation requires immediate attention due to the risk of hemorrhage and shock, making it the highest priority. This type of injury can lead to significant blood loss and impaired perfusion, which can be life-threatening if not addressed promptly. While a 10 cm laceration, a fractured tibia, and a 95% full-thickness body burn are serious injuries requiring urgent care, they do not pose the same immediate threat to life as a below-the-knee amputation. The laceration may require suturing to control bleeding and prevent infection, the fractured tibia needs stabilization to prevent further damage and pain, and the burn necessitates immediate management to prevent complications, but they are not as acutely life-threatening as the amputation.

Correct Answer: C

Rationale: An oxygen saturation of 90% is below the expected reference range and could indicate respiratory depression, a serious side effect of morphine. This finding requires immediate attention as it may lead to hypoxia. Nausea (choice A) is a common side effect of morphine but does not pose an immediate threat. A urinary output of 20 mL/hr (choice B) may indicate decreased renal perfusion but is not as critical as respiratory compromise. A respiratory rate of 14/min (choice D) is within the normal range and does not suggest immediate danger.

Correct Answer: D

Rationale: After surgery, key signs of infection include redness, swelling, and fever. Redness and swelling can indicate inflammation at the surgical site, while fever is a systemic response to infection. Choosing 'All of the above' (Option D) is the correct answer because all three signs are commonly associated with post-surgical infections. Options A, B, and C are incorrect as each of them individually can be a sign of infection, but considering all three together provides a more comprehensive assessment for post-operative infection.

Correct Answer: D

Rationale: Avoiding sun exposure is crucial to prevent skin irritation and burns in clients undergoing radiation therapy. Radiation therapy makes the skin more sensitive to sunlight, increasing the risk of skin damage. Applying heat packs (choice A) can exacerbate skin irritation as heat can further irritate the skin that is already sensitive due to radiation. Using perfumed soap (choice B) can further irritate the skin due to its harsh chemicals, potentially worsening skin reactions. While keeping the area moist with lotion (choice C) may seem beneficial, some lotions contain ingredients that can worsen skin reactions during radiation therapy. Therefore, avoiding sun exposure to the treated area (choice D) is the most appropriate action to prevent skin irritation and damage during radiation therapy.
