Nursing Elites

1. A client has been prescribed vasopressin for the treatment of diabetes insipidus. What is the expected pharmacologic action of this medication?

• A. To stimulate the pancreas to secrete insulin
• B. To slow the absorption of glucose in the intestine
• C. To increase reabsorption of water in the renal tubules
• D. To increase blood pressure

Correct answer: C

Rationale: The correct answer is C: To increase reabsorption of water in the renal tubules. Vasopressin, also known as antidiuretic hormone (ADH), works by increasing the reabsorption of water in the renal tubules, which helps to concentrate urine and reduce excessive urination in diabetes insipidus. Choice A is incorrect as vasopressin does not stimulate the pancreas to secrete insulin. Choice B is incorrect as vasopressin does not affect the absorption of glucose in the intestine. Choice D is incorrect as vasopressin's primary action is not to increase blood pressure, although it can have some vasoconstrictive effects.

2. A client prescribed hydromorphone for severe pain has a decreased respiratory rate from 16 breaths per minute to 6. Which of the following medications should the nurse prepare to administer?

• A. Flumazenil
• B. Naloxone
• C. Activated charcoal
• D. Aluminum hydroxide

Correct answer: B

Rationale: Naloxone is the correct answer as it is used to reverse opioid-induced respiratory depression. Hydromorphone is an opioid medication that can cause respiratory depression at high doses. Naloxone is an opioid antagonist that competes with opioids at receptor sites, reversing the effects of opioids like hydromorphone. Flumazenil (Choice A) is a benzodiazepine antagonist used for benzodiazepine overdose, not opioid overdose. Activated charcoal (Choice C) is used for toxin ingestion to prevent absorption in the gastrointestinal tract, but it is not indicated for opioid overdose. Aluminum hydroxide (Choice D) is an antacid and would not be the appropriate intervention for respiratory depression caused by opioid overdose.

3. A nurse is providing client education regarding lithium therapy. Which of the following instructions should the nurse include?

• A. Take with food to decrease nausea
• B. Avoid excessive intake of caffeinated beverages
• C. Monitor for signs of dehydration
• D. Restrict salt intake to prevent water retention

Correct answer: B

Rationale: The correct answer is B. The nurse should instruct the client to avoid excessive intake of caffeinated beverages as they can interfere with lithium levels. Option A is incorrect as lithium is usually recommended to be taken on an empty stomach. Option C is not directly related to lithium therapy. Option D is not a typical instruction for lithium therapy.

4. A nurse is preparing to administer ondansetron to a client. Which of the following therapeutic effects should the nurse expect from this medication?

• A. Decreased nausea
• B. Increased appetite
• C. Increased heart rate
• D. Relief of headache

Correct answer: A

Rationale: The correct answer is A: Decreased nausea. Ondansetron is classified as an antiemetic medication, which means it is used to relieve nausea and vomiting by blocking serotonin in the chemoreceptor trigger zone. Therefore, the nurse administering ondansetron should expect a therapeutic effect of decreased nausea. Choice B, increased appetite, is incorrect as ondansetron does not affect appetite. Choice C, increased heart rate, is incorrect as ondansetron does not have a direct effect on heart rate. Choice D, relief of headache, is also incorrect as the primary therapeutic effect of ondansetron is to alleviate nausea and vomiting, not headaches.

5. A client has been prescribed isosorbide mononitrate. Which of the following should the nurse include in the client education related to this medication?

• A. This medication is prescribed for long-term therapy prophylaxis against anginal attacks
• B. Do not crush this medication
• C. Take the medication in the evening after dinner
• D. Do not take an additional tablet if you experience chest pain

Correct answer: A

Rationale: The correct answer is A because isosorbide mononitrate is used for long-term prophylaxis against anginal attacks. Choice B is incorrect because isosorbide mononitrate should not be crushed. Choice C does not specify a particular time for medication administration. Choice D is incorrect because isosorbide mononitrate is not meant to be taken as needed for chest pain; it is part of a long-term therapy plan.
