1. A patient has experienced a severe third-degree burn to the trunk in the last 36 hours. Which phase of burn management is the patient in?
- A. Shock phase
- B. Emergent phase
- C. Healing phase
- D. Wound proliferation phase
Correct answer: A
Rationale: The correct answer is A: Shock phase. The shock phase occurs within the first 24-48 hours of burn management. During this phase, the focus is on stabilization, fluid resuscitation, and monitoring for potential complications. Choice B, the Emergent phase, is incorrect as it refers to the initial phase of burn care immediately after the injury. Choice C, the Healing phase, occurs later in the treatment process when the wound starts to repair itself. Choice D, the Wound proliferation phase, is not a recognized phase in burn management.
2. The nurse is caring for a client with cirrhosis of the liver and suspects that the client may be developing hepatic encephalopathy. Which assessment by the nurse suggests that the client is developing this complication?
- A. Asterixis
- B. Hypertension
- C. Kussmaul respirations
- D. Lethargy
Correct answer: A
Rationale: Asterixis, also known as flapping tremors, is a characteristic sign of hepatic encephalopathy. It is a flapping tremor of the hands when the wrists are extended, indicating neurological impairment. Hypertension and Kussmaul respirations are not directly associated with hepatic encephalopathy. Lethargy is a common symptom but not a specific sign that suggests the development of hepatic encephalopathy.
3. A client arrives in the emergency department after severely lacerating the left hand with a knife. HR 96, BP 150/88, R36. The client is extremely anxious and crying uncontrollably. Based on this assessment, the nurse anticipates that this client would be in which acid-base imbalance?
- A. Respiratory acidosis
- B. Respiratory alkalosis
- C. Metabolic acidosis
- D. Metabolic alkalosis
Correct answer: B
Rationale: The correct answer is respiratory alkalosis. Hyperventilation due to anxiety, pain, shock, severe infection, fever, or liver failure can lead to respiratory alkalosis. In this scenario, the client is extremely anxious and crying uncontrollably, indicating an increased respiratory rate and CO2 loss. Respiratory acidosis (choice A) is incorrect as it is characterized by an increase in CO2 levels, not a loss. Metabolic acidosis (choice C) involves a decrease in blood pH due to an accumulation of acids or loss of bicarbonate, which is not the case here. Metabolic alkalosis (choice D) results from excess bicarbonate or a loss of acids, not from increased CO2 loss due to hyperventilation.
4. The chemotherapeutic agent 5-fluorouracil (5-FU) is ordered for a client as an adjunct measure to surgery. Which statement about chemotherapy is true?
- A. It is a local treatment affecting only tumor cells.
- B. It is a systemic treatment affecting both tumor and normal cells.
- C. It has not yet been proven an effective treatment for cancer.
- D. It is often the drug of choice because it causes few, if any, side effects.
Correct answer: B
Rationale: The correct answer is that chemotherapy is a systemic treatment affecting both tumor and normal cells. 5-FU, as an antimetabolic drug, inhibits DNA synthesis and interferes with cell replication systemically. It affects all rapidly growing cells, including malignant and normal ones. This drug is used as adjuvant therapy for various cancers. Choice A is incorrect because chemotherapy affects both tumor and normal cells, not just tumor cells. Choice C is incorrect as chemotherapy has been proven effective in treating cancer. Choice D is incorrect because chemotherapy often causes side effects like bone marrow depression, anorexia, stomatitis, nausea, and vomiting.
5. Metformin (Glucophage) is administered to clients with type II diabetes mellitus. Metformin is an example of:
- A. an antihyperglycemic agent.
- B. a hypoglycemic agent.
- C. an insulin analogue.
- D. a pancreatic alpha cell stimulant
Correct answer: A
Rationale: Metformin is classified as an antihyperglycemic agent because it works by reducing hepatic glucose output and decreasing glucose absorption from the gut, thereby preventing hyperglycemia. Choice B, a hypoglycemic agent, is incorrect as hypoglycemic agents stimulate insulin production, which is not the mechanism of action of metformin. Choice C, an insulin analogue, is incorrect as metformin is not a type of insulin but a distinct medication. Choice D, a pancreatic alpha cell stimulant, is incorrect as metformin does not stimulate any pancreatic cells, but rather acts on the liver and gut to lower blood sugar levels.
