Correct Answer: C

Rationale: Rationale: 1. Pulmonary edema is caused by increased hydrostatic pressure in the pulmonary circulation. 2. Elevated left ventricular end-diastolic pressure signifies heart failure, a common cause of pulmonary edema. 3. A rise in pulmonary venous pressure is a consequence of increased hydrostatic pressure. Therefore, all three alterations (A, B, D) are characteristic of pulmonary edema. Option C is correct. Choices A, B, and D are incorrect because they are all individually associated with pulmonary edema and collectively represent the condition.

Correct Answer: A

Rationale: The correct answer is A: Measure intake and output. Monitoring intake and output is crucial in assessing electrolyte imbalances and dehydration in clients with neurologic deficits. Electrolyte imbalances can lead to neurological complications, so accurate monitoring is essential. Mini-mental status and Glasgow Coma scale are assessments of mental status, not electrolyte balance. Vital signs can provide some information, but intake and output measurement is more specific for assessing electrolyte imbalances and dehydration.

Correct Answer: B

Rationale: The correct answer is B: The potential complication. In a collaborative problem, the focus of a diagnostic statement should be on identifying any potential complications that may arise due to the client's condition or treatment. This allows nurses and other healthcare professionals to anticipate and address these complications proactively. A: The client problem - While important, the client problem is usually addressed in the nursing diagnosis rather than the diagnostic statement for a collaborative problem. C: The nursing diagnosis - The nursing diagnosis focuses on the actual or potential health problems that the client is experiencing, which is different from the focus of a diagnostic statement for a collaborative problem. D: The medical diagnosis - The medical diagnosis is the identification of a disease or condition by a healthcare provider, which is not the focus when identifying potential complications in a collaborative problem.

Correct Answer: B

Rationale: The correct answer is B: It minimizes the risk of circulatory overload. When a venous access device dislodges during a transfusion, there is a risk of the infusion going into the surrounding tissues instead of the vein, leading to circulatory overload. This can result in fluid overload and potentially lead to serious complications such as heart failure. Monitoring the device ensures that the medication is delivered safely and effectively into the bloodstream. Choices A, C, and D are incorrect: A: Monitoring the device does not directly minimize the risk of phlebitis, which is inflammation of the vein. C: Monitoring the device does not directly minimize the risk of pulmonary complications, which are not typically associated with a dislodged venous access device. D: Monitoring the device does not directly minimize the risk of localized edema embolism, which is a blockage caused by a blood clot, air bubble, or other material in a blood vessel.

Correct Answer: B

Rationale: The correct answer is B: 20,000/ul. A platelet count below 20,000/ul puts the client at the highest risk for cerebral hemorrhage due to severe thrombocytopenia. Platelets are essential for blood clotting, and a low count increases the risk of spontaneous bleeding, especially in critical organs like the brain. Choices A, C, and D have platelet counts that are higher than the critical level of 20,000/ul, so they do not pose as high a risk for cerebral hemorrhage. Option D, 500/ul, is extremely low and would likely lead to severe bleeding, but the critical threshold for cerebral hemorrhage is considered to be around 20,000/ul.
