1. 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.
2. Which of the following should not be included in the teaching for clients who take oral iron preparations?
- A. Mix the liquid iron preparation with antacids to reduce GI distress.
- B. Take the iron with meals if GI distress occurs.
- C. Liquid forms should be taken with a straw to avoid discoloration of tooth enamel.
- D. Oral forms should be taken with juice, not milk.
Correct answer: A
Rationale: The correct answer is to mix the liquid iron preparation with antacids to reduce GI distress. This statement is incorrect because iron should not be mixed with antacids as it can significantly reduce the absorption of iron. Choice B is a good recommendation as taking iron with meals can help reduce gastrointestinal distress. Choice C is also correct as liquid forms of iron should be taken with a straw to prevent the discoloration of tooth enamel. Choice D is incorrect as iron preparations can be taken with juice or water, but not with milk, as calcium in milk can inhibit iron absorption.
3. A central venous pressure reading of 11cm/H(2)O of an IV of normal saline is determined by the nurse caring for the patient. The patient has a diagnosis of pericarditis. Which of the following is the most applicable?
- A. The patient has a condition of hypovolemia.
- B. Not enough fluid has been given to the patient.
- C. Pericarditis may cause pressures greater than 10cm/H(2)O with testing of CVP.
- D. The patient may have a condition of arteriosclerosis.
Correct answer: C
Rationale: A central venous pressure reading above 10cm/H(2)O may indicate a condition of pericarditis, as the inflammation and fluid accumulation around the heart can lead to elevated pressures. Choices A, B, and D are incorrect. Hypovolemia would typically result in lower CVP readings, not higher. Not enough fluid given would also lead to lower CVP levels. Arteriosclerosis is not directly related to CVP readings in the context of pericarditis.
4. Which factor in a client’s health history increases their risk for cancer?
- A. Family history and environment
- B. Alcohol and smoking
- C. Alcohol consumption and smoking
- D. Proximity to an electric plant and water source
Correct answer: B
Rationale: The correct answer is 'Alcohol and smoking.' Both alcohol consumption and smoking are well-known risk factors for various types of cancer. They have a synergistic effect, meaning their combined impact raises the risk significantly. Family history and environment (Choice A) may play a role in certain cancers, but alcohol and smoking are more directly linked to increased cancer risk. Proximity to an electric plant and water source (Choice D) is not typically associated with an increased risk of cancer compared to alcohol and smoking.
5. During a stress test, a patient complains of severe chest pain. Which of the following medications is the most appropriate to relieve this discomfort?
- A. Aspirin
- B. Diazoxide
- C. Procardia
- D. Mannitol
Correct answer: C
Rationale: In this scenario, the most appropriate medication to relieve severe ischemic chest pain during a stress test is Procardia. Procardia, a calcium channel blocker, is effective in quickly alleviating chest pain by dilating coronary arteries, improving blood flow to the heart muscle. Aspirin, although important for antiplatelet effects, is not the best choice for immediate relief of severe chest pain. Diazoxide is a vasodilator used in hypertensive emergencies, not for acute chest pain. Mannitol is an osmotic diuretic used to reduce intracranial pressure, not for chest pain relief.
