An 18-year-old male client admitted with heat stroke begins to show signs of disseminated intravascular coagulation (DIC). Which of the following laboratory findings is most consistent with DIC?

Correct Answer: A

Rationale: The correct answer is A: Low platelet count. In DIC, there is widespread activation of coagulation leading to consumption of platelets and clotting factors. This results in a low platelet count due to their excessive use in forming microthrombi. Elevated fibrinogen levels (B) occur in response to increased clotting activity. Low levels of fibrin degradation products (C) are not consistent with DIC as there is increased fibrin breakdown in DIC. Reduced prothrombin time (D) is not indicative of DIC as it measures the extrinsic pathway of coagulation and may be normal or prolonged in DIC.

Correct Answer: D

Rationale: Step 1: Unstable angina indicates a serious condition requiring immediate intervention. Step 2: Percutaneous transluminal coronary angioplasty (PTCA) is a surgical procedure used to open blocked coronary arteries. Step 3: PTCA helps improve blood flow to the heart, reducing the risk of a heart attack. Step 4: Cardiac catheterization (choice A) is a diagnostic procedure, not a direct treatment. Step 5: Echocardiogram (choice B) is an imaging test, not a surgical intervention. Step 6: Nitroglycerin (choice C) is a medication used for symptom relief, not a surgical solution.

Correct Answer: A

Rationale: The correct answer is A because it directly addresses the issue of abuse by asking if the wife and child are being threatened or hurt by the partner. This question is clear, specific, and focuses on the potential abuse situation. It allows the nurse to gather crucial information to assess the safety of the family. Choice B is not as effective because it only asks if the wife is frightened, which may not necessarily reveal if abuse is present. Choice C is too vague and open-ended, not directly addressing the suspected abuse. Choice D focuses on arguments, which may not uncover the extent of abuse occurring in the household. Therefore, A is the most appropriate question in this situation.

Correct Answer: A

Rationale: The correct answer is A because it acknowledges the client's pain while also addressing the fact that test results are negative, validating their experience. This response shows empathy and understanding. B is incorrect as it dismisses the client's pain, potentially causing them to feel unheard. C is incorrect as it suggests avoiding the issue rather than addressing it. D is not the best response as it does not acknowledge the negative test results, which may confuse the client.

Correct Answer: D

Rationale: The correct answer is D because rearranging the environment to activate the child is not a recommended therapeutic approach for caring for an autistic child. Autistic children may struggle with changes in their environment, so rearranging it could lead to increased stress and anxiety, rather than therapeutic benefits. A: Engaging in diversionary activities when acting-out can help redirect behavior and provide a positive outlet for emotions. B: Providing an atmosphere of acceptance fosters a sense of security and belonging for the child. C: Providing safety measures is crucial to ensure the well-being of the child and prevent any harm. In summary, D is incorrect as it could potentially disrupt the child's sense of stability, while A, B, and C are all important aspects of the therapeutic approach in caring for an autistic child.
