Correct Answer: A

Rationale: Corrected Rationale: Untreated DVT can lead to complications such as pulmonary embolism and stroke. Pulmonary embolism occurs when a blood clot from the leg travels to the lungs, potentially blocking blood flow and causing respiratory distress. Stroke can occur if a blood clot dislodges from the leg veins, travels to the brain, and obstructs a blood vessel, leading to brain tissue damage. Both of these complications are life-threatening if not managed promptly. The other choices (B, C, D) do not represent common complications of untreated DVT and are therefore incorrect.

Correct Answer: A

Rationale: Corrected Rationale: Bradycardia is a common sign of hypoglycemia due to the body's response to low blood sugar. During hypoglycemia, the body releases epinephrine, leading to sympathetic nervous system activation. This can result in bradycardia as a compensatory mechanism to preserve glucose for vital organs such as the brain. Tachycardia, hypotension, and diaphoresis are more commonly associated with hypoglycemia when it progresses to severe stages and the body's compensatory mechanisms are overwhelmed.

Correct Answer: B

Rationale: The correct answer is to consult with a dietitian to create a high-protein diet. A serum albumin level of 3 g/dL indicates hypoalbuminemia, which can impair wound healing. Consulting with a dietitian to optimize the client's protein intake is crucial in promoting wound healing for pressure ulcers. Increasing the protein intake in the diet (Choice A) may not be sufficient without proper guidance from a dietitian. Increasing the IV fluid infusion rate (Choice C) is not directly related to addressing the protein deficiency. Administering a protein supplement (Choice D) should be guided by a healthcare professional's recommendation after consulting with a dietitian.

Correct Answer: A

Rationale: The correct intervention is to avoid taking blood pressures on the arm with the AV fistula. This is crucial to prevent complications such as damage to the fistula. Checking the fistula site for pallor is not as important as avoiding blood pressures on the affected arm. Placing warm compresses over the fistula site is not recommended as it can increase the risk of infection. Keeping the client's arm elevated on two pillows is not necessary for the care of an AV fistula.

Correct Answer: A

Rationale: The correct answer is to insert a chest tube. This intervention is considered the definitive treatment for a pneumothorax as it helps remove air or fluid from the pleural space, re-expanding the lung. Administering oxygen (Choice B) can be supportive but is not the primary intervention to treat a pneumothorax. Monitoring respiratory rate (Choice C) is important but does not address the underlying issue of air in the pleural space. Administering analgesics (Choice D) may help manage pain but does not treat the pneumothorax itself.
