A client is undergoing chemotherapy and is at risk for developing thrombocytopenia. What precaution should the nurse teach the client to minimize the risk of bleeding?

Correct Answer: A

Rationale: The correct answer is A: Use a soft-bristled toothbrush. Chemotherapy can cause low platelet levels, increasing the risk of bleeding. Using a soft-bristled toothbrush can help prevent gum bleeding and trauma to the gums, reducing the risk of bleeding. Engaging in daily aerobic exercise (B) can increase the risk of injury and bleeding for a client with thrombocytopenia. Taking aspirin (C) can further decrease platelet function and increase bleeding risk. Using an electric razor (D) is recommended to prevent skin cuts and bleeding due to the fragile skin associated with chemotherapy-induced thrombocytopenia.

Correct Answer: A

Rationale: The correct answer is A: Administer pain medication as prescribed. This is the highest priority because acute pancreatitis is a painful condition, and managing pain is crucial for the client's comfort and well-being. Pain control also helps reduce stress on the pancreas and can aid in preventing complications. Choice B is incorrect because while monitoring serum amylase and lipase levels is important in diagnosing pancreatitis and assessing response to treatment, it is not the highest priority intervention. Choice C is incorrect as encouraging oral intake of clear liquids may exacerbate pancreatitis symptoms and lead to further complications. Choice D is incorrect as assessing bowel sounds, while important for monitoring gastrointestinal function, is not the highest priority in the acute management of pancreatitis.

Correct Answer: B

Rationale: The correct answer is B: Intracranial pressure (ICP) of 20 mm Hg. Elevated ICP can lead to increased intracranial pressure, which can further damage brain tissue and impair cerebral perfusion. This is a critical finding that requires immediate intervention to prevent further brain damage. A: Urine output of 100 mL/hour is within the normal range and does not pose an immediate threat to the client's condition. C: Respiratory rate of 12 breaths/minute is within normal limits and does not indicate an immediate concern. D: Mean arterial pressure (MAP) of 70 mm Hg is within the normal range for most adults and does not require immediate intervention in this scenario.

Correct Answer: B

Rationale: The correct answer is B: Hyperpigmentation and hypotension. Addison's disease is characterized by adrenal insufficiency, leading to low cortisol and aldosterone levels. Hyperpigmentation occurs due to elevated levels of ACTH, causing melanin deposition. Hypotension results from aldosterone deficiency, leading to sodium and water loss. Choice A is incorrect because Addison's disease does not typically present with hypertension or hyperglycemia. Choice C is incorrect as exophthalmos and tachycardia are not typically associated with Addison's disease. Choice D is incorrect as weight gain and fluid retention are not common manifestations of Addison's disease.

Correct Answer: C

Rationale: The correct answer is C: Place the client in Trendelenburg position. This is the first action to take in a client with suspected air embolism, a potential complication of central line insertion. Placing the client in Trendelenburg position with the head down and the legs elevated can help prevent air from reaching the heart and lungs. This action can help stabilize the client's condition before further interventions can be implemented. Stopping the TPN infusion (choice A) can be important, but the priority in this situation is to address the potential air embolism. Notifying the healthcare provider (choice B) can be done after the immediate intervention. Administering oxygen (choice D) is important, but placing the client in Trendelenburg position takes precedence in this emergency situation.
