Correct Answer: D

Rationale: Thrombocytopenia is a condition characterized by a low platelet count, which can lead to an increased risk of bleeding. Patients with thrombocytopenia are at risk for injury due to potential bleeding complications. Therefore, the appropriate nursing diagnosis to protect the patient from further injury in this case would be "Risk for injury related to thrombocytopenia." This nursing diagnosis allows the nurse to assess for signs of bleeding, implement interventions to prevent injury, and closely monitor the patient's platelet levels to prevent complications.

Correct Answer: A

Rationale: Grounded theory is a qualitative research method that focuses on generating theory from data rather than testing pre-existing theories. In this scenario, where the goal is to explore social processes observed in the delivery room activities, grounded theory would be the most appropriate method. This method allows researchers to systematically collect and analyze data in order to develop theoretical explanations for social phenomena. By using grounded theory, researchers can explore the interactions, behaviors, and social processes at play in the delivery room in a structured and systematic way, thereby gaining insights into these phenomena through an inductive approach.

Correct Answer: D

Rationale: Third-degree perineal lacerations are significant injuries that require careful monitoring for signs of infection or wound dehiscence, which are potential complications that could hinder optimal wound healing. Signs of infection may include increased redness, warmth, swelling, pain, and purulent drainage from the wound site. Dehiscence refers to the separation of the wound edges, which can be a serious complication requiring immediate attention. By closely monitoring the incision site for these signs, the nurse can promptly intervene if any complications arise, ensuring proper healing and preventing further complications. While providing perineal care, proper application of peri-pads, and encouraging sitz baths are important for comfort and cleanliness, monitoring for complications takes priority in promoting optimal wound healing in this scenario.

Correct Answer: A

Rationale: Molluscum contagiosum is a viral skin infection caused by the poxvirus. It commonly presents as flesh-colored, dome-shaped papules with central umbilication on the face, trunk, and extremities. The central umbilication indicates the presence of a crater-like indentation in the center of the lesion. It is a benign condition and usually self-limited, but it can be persistent and contagious. Treatment options include cryotherapy, curettage, topical therapies, and observation. Acne vulgaris presents with comedones, papules, pustules, and nodules primarily on the face, chest, and back. Sebaceous hyperplasia is characterized by yellowish papules with central dell on the face. Basal cell carcinoma typically presents as a pearly papule with telangiectasias and may have ulceration or bleeding.

Correct Answer: A

Rationale: The clinical presentation of recurrent episodes of epistaxis, gum bleeding, and easy bruising, along with laboratory findings of prolonged bleeding time, normal platelet count, and normal coagulation studies (PT and aPTT) are highly suggestive of Von Willebrand disease. Von Willebrand disease is the most common inherited bleeding disorder and is characterized by a deficiency or dysfunction of von Willebrand factor (vWF), which plays a key role in platelet adhesion and aggregation. The prolonged bleeding time is due to impaired platelet adhesion to the damaged vessel wall in the absence of functional vWF. Normal platelet count and normal PT/aPTT help differentiate Von Willebrand disease from other bleeding disorders such as hemophilia and platelet function disorders like Glanzmann thrombasthenia and Bernard-Soulier syndrome.
