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 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.

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 caring for a client prescribed enoxaparin for deep vein thrombosis prophylaxis. Which of the following client assessments requires immediate intervention?

• A. Platelet count of 95,000/mm³
• B. Blood pressure of 145/90 mmHg
• C. Heart rate of 95 beats per minute
• D. Pain at the injection site

Correct answer: A

Rationale: A platelet count of 95,000/mm³ requires immediate intervention as it is low and increases the risk of bleeding, which is a potential complication of enoxaparin therapy. Low platelet counts can predispose the patient to hemorrhage, and administering anticoagulants like enoxaparin in such cases can further increase the bleeding risk. Monitoring platelet counts is crucial during anticoagulant therapy to prevent serious bleeding complications. The other options do not pose immediate risks related to enoxaparin therapy. A slightly elevated blood pressure, a heart rate of 95 beats per minute, and pain at the injection site are common findings that may not warrant immediate intervention in this context.

5. A nurse is providing client education on how to administer insulin. Which of the following instructions should the nurse include?

• A. Administer the insulin into the deltoid muscle
• B. Rotate injection sites to prevent lipodystrophy
• C. Massage the site after injection
• D. Use the same site for each injection

Correct answer: B

Rationale: The correct instruction for administering insulin is to rotate injection sites to prevent lipodystrophy, a common complication of insulin therapy. Injecting into the deltoid muscle (Choice A) is not recommended for insulin injections. Massaging the site after injection (Choice C) is not necessary and can potentially increase the risk of lipodystrophy. Using the same site for each injection (Choice D) can lead to localized tissue damage and absorption irregularities, making it an incorrect choice.
