Correct Answer: B

Rationale: The correct answer is B because an incomplete abortion at 16 weeks may require a D&C to remove remaining tissue to prevent infection and complications. Incomplete abortion means not all fetal tissue has been expelled, posing a risk. Choice A (complete abortion at 8 weeks) does not require a D&C as all tissue is expelled. Choice C (threatened abortion at 6 weeks) does not necessitate immediate intervention. Choice D (incomplete abortion at 10 weeks) is not the best choice as the risk of complications increases with gestational age.

Correct Answer: A

Rationale: The correct answer is A: Type I hypersensitivity reaction. This type of reaction involves the release of histamine from mast cells and basophils, leading to symptoms like hives. It is characterized by the involvement of IgE antibodies. In this case, the patient developed hives quickly after exposure to the allergen, indicating an immediate hypersensitivity reaction typical of Type I. Choices B, C, and D are incorrect because they are associated with different mechanisms and timeframes of hypersensitivity reactions. Type II involves antibody-mediated cell destruction, Type III involves immune complex deposition, and Type IV is a delayed-type hypersensitivity reaction mediated by T cells, none of which are consistent with the rapid onset of hives seen in this patient.

Correct Answer: A

Rationale: The correct answer is A. Research studies have consistently shown that families' needs for information and support often go unmet in hospital settings when caring for dying patients. This is a crucial deficiency as effective communication and support for families can greatly impact the quality of care provided to the dying patient. When families are not adequately informed and supported, it can lead to increased stress, confusion, and dissatisfaction with the care provided. Choices B, C, and D are incorrect because they do not address the specific deficiency identified in research studies. While pain control, communication, and attention from caregivers are important aspects of end-of-life care, the primary focus in this scenario is on the unmet needs of families for information and support. Ignoring families' needs can have significant negative consequences on the overall care provided to the dying patient.

Correct Answer: B

Rationale: The correct answer is B: Protect the patient's airway. In anaphylaxis, airway compromise can lead to respiratory distress and even respiratory arrest. The priority is to ensure the patient has a patent airway to maintain oxygenation. This can be achieved through interventions such as positioning, oxygen therapy, and potentially intubation if needed. Monitoring the patient's level of consciousness (A) is important but secondary to ensuring airway patency. Providing psychosocial support (C) is not the immediate priority in anaphylaxis. Administering medications (D) is also important but only after ensuring the airway is protected.

Correct Answer: B

Rationale: The correct answer is B: In a flat side-lying position. Rationale: 1. A flat side-lying position helps reduce pressure on the surgical site, promoting comfort and preventing injury. 2. This position minimizes strain on the spine and supports proper alignment. 3. High Fowlers position may increase pressure on the surgical area due to increased intra-abdominal pressure. 4. Trendelenberg position and reverse Trendelenberg position are not appropriate for spine surgery patients as they can cause increased blood flow to the surgical site, leading to potential complications.
