Correct Answer: B

Rationale: The correct answer is B: Acute pain. NANDA-I (North American Nursing Diagnosis Association International) approves standardized nursing diagnoses to guide nursing care. Acute pain is a NANDA-I approved diagnosis as it helps identify and address a patient's pain experience. It is specific, measurable, and relevant for care planning. Sore throat (A) is a symptom, not a diagnosis. Sleep apnea (C) and heart failure (D) are medical conditions, not nursing diagnoses. The focus of nursing care plans is on identifying patient responses to health conditions, which is why acute pain is the most appropriate choice.

Correct Answer: B

Rationale: The correct answer is B because performing Valsalva maneuver can lead to a sudden drop in blood pressure, causing the client to lose consciousness. This occurs due to the increased intra-abdominal pressure leading to decreased venous return to the heart. Choices A, C, and D are incorrect as they do not accurately reflect the consequences of Valsalva maneuver. Option A stating that the client's blood pressure will decrease momentarily is incorrect as it actually increases initially. Option C suggesting that the client may suffer from a myocardial infarction is incorrect as Valsalva maneuver does not directly cause heart attacks. Option D implying that the client's blood pressure will increase momentarily is also incorrect as the immediate effect is a rise followed by a significant drop.

Correct Answer: B

Rationale: The correct answer is B because hemoglobin carries oxygen to the tissues, and with a low hemoglobin level of 6 g/dL, there is insufficient oxygen-carrying capacity to meet the body's needs, leading to shortness of breath (SOB). Choice A is incorrect as anemia affects oxygen transport, not absorption. Choice C is incorrect as anemia affects oxygen delivery, not nutrient delivery. Choice D is incorrect as the primary reason for SOB in this scenario is the lack of oxygen-carrying capacity due to low hemoglobin levels, not lung damage from blood loss.

Correct Answer: A

Rationale: The correct answer is A: Platelet count, prothrombin time, and partial thromboplastin time. These parameters are essential in monitoring DIC because platelet count reflects the risk of bleeding, while prolonged prothrombin time and partial thromboplastin time indicate impaired clotting function, which is characteristic of DIC. Explanation for why other choices are incorrect: - Choice B: Blood glucose levels and WBC count are not specific indicators for DIC monitoring. - Choice C: Thrombin time, calcium levels, and potassium levels do not directly assess clotting abnormalities associated with DIC. - Choice D: While fibrinogen level is important in DIC, WBC count alone is not a specific indicator for monitoring DIC.

Correct Answer: A

Rationale: The correct answer is A because thalassemia is a genetic blood disorder that can cause anemia and fatigue. By maintaining the client on bed rest and protecting them from infections, we can help prevent complications such as fatigue and infections due to reduced red blood cell production. Ambulating the client frequently (choice B) may lead to increased fatigue and risk of injury. Advising to drink 3 quarts of fluid per day (choice C) is not specific to thalassemia treatment and could potentially worsen symptoms. Instructing the client to elevate lower extremities (choice D) is not directly related to managing thalassemia and may not provide significant benefits in this context.
