A client is prescribed metronidazole for a bacterial infection. Which of the following should the nurse teach the client?

Correct Answer: A

Rationale: The correct answer is A: 'Avoid alcohol while taking this medication.' Metronidazole can cause a disulfiram-like reaction with alcohol, leading to symptoms like nausea, vomiting, flushing, and headache. Therefore, clients should be instructed to avoid alcohol consumption. Choice B is incorrect because metronidazole is not considered safe during pregnancy, especially in the first trimester. Choice C is incorrect as metronidazole is not known to cause increased appetite. Choice D is also incorrect as hair loss is not a common side effect of metronidazole.

Correct Answer: B

Rationale: When a patient has extensive burns involving the head, neck, and chest, the priority concern is airway obstruction. The proximity of the burns to the airway can lead to swelling and compromise the patient's ability to breathe. In this situation, ensuring a clear airway and adequate oxygenation takes precedence over other risks such as infection, fluid imbalance, or pain management. While these are also important considerations in burn care, the immediate threat to the patient's life from airway compromise makes it the priority for assessment and intervention.

Correct Answer: B

Rationale: The correct answer is B: Hypotension. Metoprolol, a beta-blocker, can lead to a decrease in blood pressure, resulting in hypotension. Monitoring blood pressure regularly is essential to detect and manage this adverse effect. Choices A, C, and D are incorrect because metoprolol typically does not cause bradycardia, tachycardia, or hyperglycemia as its primary adverse effects.

Correct Answer: D

Rationale: The correct answer is D because an elevated temperature is a common manifestation of dehydration. Choices A, B, and C are not indicative of dehydration. A urine specific gravity of 1.010 is within normal range, weight gain suggests fluid overload, and a hematocrit of 45% is also within normal limits and not specifically related to dehydration.

Correct Answer: B

Rationale: The correct answer is B: 'Monitor for dyskinesia.' Levodopa-carbidopa can cause dyskinesia as a side effect, which is characterized by involuntary muscle movements. Patients need to be monitored for this adverse effect and instructed to report it to their healthcare provider. Choices A, C, and D are incorrect because levodopa-carbidopa is not a cure for Parkinson's disease, it should be taken at specific times for optimal effect, and it does have side effects, such as dyskinesia.

Correct Answer: B

Rationale: In this scenario, the correct actions for the nurse to take involve ensuring patient safety and fall prevention measures. Choice B is the correct answer because instructing the patient to use the call light allows them to signal for help, applying an ambulation alarm helps detect movement, and checking on the patient hourly increases monitoring frequency. These actions are essential for preventing falls in a disoriented patient with a history of falls. Choices A, C, and D are incorrect: A does not provide adequate monitoring or fall prevention measures, C relies solely on assigning a sitter without utilizing technological aids, and D lacks continuous monitoring and specific fall prevention strategies.

Correct Answer: D

Rationale: The correct answer is D. Roast turkey is a lean protein option suitable for a low-fat diet. Rice pilaf and green beans are also low in fat. Choices A, B, and C contain high-fat ingredients like gravy, cheese, cream, and ice cream, which are not suitable for a low-fat diet.

Correct Answer: C

Rationale: The correct answer is C: Tremors. Lithium toxicity can present with symptoms such as tremors, nausea, and blurred vision. Tremors are a common early sign of lithium toxicity and should be monitored closely. While nausea and vomiting can also occur with lithium toxicity, tremors are more specific to lithium toxicity. Increased urination is not typically associated with lithium toxicity, and blurred vision is less common compared to tremors in this context.

Correct Answer: B

Rationale: The correct answer is to assess the patient's heart rate. Levothyroxine is a thyroid hormone replacement medication that can increase metabolism. One of the potential side effects of levothyroxine is tachycardia (rapid heart rate). Therefore, it is essential for the healthcare provider to assess the patient's heart rate before administering the medication to monitor for any signs of tachycardia. Giving levothyroxine with food may affect its absorption, so it is typically recommended to administer it on an empty stomach. Administering it in the evening is not necessary unless specifically prescribed by the healthcare provider, and giving it with calcium supplements can interfere with the absorption of levothyroxine.
