A nurse is preparing to administer a dose of insulin. Which of the following should the nurse do first?

Correct Answer: B

Rationale: The correct answer is to verify the client's blood glucose level first before administering insulin. This step is crucial to determine the appropriate dose of insulin based on the client's current blood glucose level. Checking the expiration date (Choice A) is important but not the first step in this scenario. Obtaining the client's weight (Choice C) is not directly related to the immediate administration of insulin. Assessing for signs of hypoglycemia (Choice D) should be done after administering insulin to monitor for potential side effects or adverse reactions.

Correct Answer: B

Rationale: The correct answer is B: Serum creatinine. Vancomycin is known to be nephrotoxic, meaning it can cause kidney damage. Monitoring serum creatinine levels is essential to assess kidney function and detect any signs of nephrotoxicity. Blood glucose levels (choice A) are not directly affected by vancomycin. INR levels (choice C) are typically monitored for clients on anticoagulants, not vancomycin. Liver function tests (choice D) are not primarily affected by vancomycin use; kidney function is of greater concern.

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.

Correct Answer: A

Rationale: Corrected Rationale: When educating a client about fluoxetine, it is essential to mention that it can take several weeks for the therapeutic effects to be noticed. This is because fluoxetine is an SSRI that requires time to build up in the body and start producing its intended effects. Choice B is incorrect as fluoxetine is not an antipsychotic medication but an SSRI. Choice C is inaccurate because fluoxetine can be taken at any time of the day, and there is no specific requirement to take it at night. Choice D is incorrect as all medications, including fluoxetine, have potential side effects that should be discussed with the client.

Correct Answer: B

Rationale: The correct answer is to 'Monitor for dyskinesia.' Carbidopa-levodopa can cause dyskinesia as a side effect, characterized by involuntary movements. Monitoring for this side effect is crucial. Choice A is incorrect because carbidopa-levodopa helps manage symptoms of Parkinson's disease but does not cure it. Choice C is incorrect because carbidopa-levodopa should be taken on an empty stomach to enhance absorption. Choice D is incorrect because carbidopa-levodopa is not an opioid medication.
