Correct Answer: A

Rationale: After a hip spica cast is applied, it is important to facilitate drying by exposing the cast to air and turning the child frequently, approximately every 2 hours. This helps ensure even drying and prevents skin breakdown. Using a heat lamp can cause burns and should be avoided. Handling the cast with the abductor bar is not necessary for the drying process and may cause discomfort to the child. Turning the child as little as possible is not recommended as regular turning helps prevent complications like pressure ulcers and stiffness.

Correct Answer: D

Rationale: A client diagnosed with active tuberculosis should be placed in isolation in a negative-pressure room to prevent transmission of infection to others. Placing the client in a negative-pressure room ensures that air is exhausted to the outside and received from surrounding areas, preventing tuberculin particles from traveling through the ventilation system and infecting others. Initiating standard precautions, as mentioned in choice C, is essential for infection control but is not specific to preventing transmission in the case of tuberculosis. Beginning drug therapy within 72 hours of diagnosis, as in choice A, is crucial for the treatment of tuberculosis but does not directly address preventing transmission. Placing the client in a positive-pressure room, as in choice B, is incorrect as positive-pressure rooms are used for clients with compromised immune systems to prevent outside pathogens from entering the room, which is not suitable for a client with active tuberculosis.

Correct Answer: C

Rationale: In this scenario, the nurse observed carpal spasms in the patient's right hand, indicating a positive Trousseau's sign, which is associated with hypocalcemia. Patients with acute pancreatitis are at risk for hypocalcemia, hence the nurse should promptly check the calcium level in the chart to assess the patient's condition. Notifying the healthcare provider comes after confirming the calcium level. There is no indication to ask about arm pain or to retake the blood pressure, as the primary concern is addressing the potential hypocalcemia.

Correct Answer: A

Rationale: The correct answer is 'Hypotension.' Flomax (Tamsulosin) is known to cause orthostatic hypotension, especially in the elderly, leading to a sudden drop in blood pressure when standing up. This side effect can result in dizziness, falls, and injury, especially concerning for a patient living in an upstairs apartment. Tachycardia (increased heart rate) and back pain are less commonly associated with Flomax use, while difficulty urinating is a symptom that Flomax is intended to improve in patients with Benign Prostatic Hyperplasia.

Correct Answer: A

Rationale: Melena is the passage of black, tarry stools due to the presence of blood in the gastrointestinal tract, usually originating from the upper digestive system. In the context of a Duodenal Ulcer, melena can occur as a result of bleeding in the duodenum or the upper part of the small intestine. This finding is significant as it indicates potential gastrointestinal bleeding, which is a common complication of duodenal ulcers. Nausea (Choice B) is a nonspecific symptom that may be present with various gastrointestinal conditions but is not specific to duodenal ulcers. Hernia (Choice C) involves the protrusion of an organ through the wall of the cavity that normally contains it and is not directly related to the symptoms of a duodenal ulcer. Hyperthermia (Choice D), which refers to an elevated body temperature, is not typically associated with duodenal ulcers unless there are severe complications present.
