Nursing Elites

1. 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.

2. A nurse is caring for a client prescribed digoxin. Which of the following should alert the nurse to possible digitalis toxicity?

• A. Anorexia and weakness
• B. Hyperactivity and hunger
• C. Tachycardia and increased urination
• D. Polyphagia and polydipsia

Correct answer: A

Rationale: The correct answer is A: Anorexia and weakness. These symptoms are early indicators of potential digitalis toxicity. Anorexia refers to a loss of appetite, which can be a sign of toxicity, and weakness can indicate an issue with digoxin. Choices B, C, and D are incorrect. Hyperactivity and hunger, tachycardia and increased urination, as well as polyphagia and polydipsia are not typically associated with digitalis toxicity.

3. A nurse is preparing to administer potassium chloride IV to a client. Which of the following actions should the nurse take to prevent complications?

• A. Administer the medication by IV bolus over 2 minutes
• B. Infuse the medication slowly using an IV pump
• C. Add the medication to an IV solution of D5W
• D. Dilute the medication in 5 mL of sterile water

Correct answer: B

Rationale: The correct action to prevent complications when administering potassium chloride IV is to infuse the medication slowly using an IV pump. Rapid administration of potassium chloride can lead to complications such as hyperkalemia and cardiac arrest. Options A, C, and D are incorrect as they do not promote the safe administration of potassium chloride. Administering the medication by IV bolus over 2 minutes is too rapid and can cause adverse effects. Adding the medication to an IV solution of D5W or diluting it in sterile water may not control the rate of administration, increasing the risk of complications.

4. 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.

5. A nurse is caring for a client newly prescribed doxazosin mesylate. Which of the following instructions should the nurse include in client education regarding taking the first dose of this medication?

• A. Change positions slowly and lie down if dizziness occurs
• B. There is no need to avoid normal activities
• C. Avoid dairy products while taking this medication
• D. Do not eat green leafy vegetables

Correct answer: A

Rationale: Corrected Rationale: First-dose orthostatic hypotension can occur with doxazosin. The nurse should advise the client to change positions slowly and lie down if dizziness occurs. Choice B is incorrect because it does not address the potential side effect of dizziness. Choice C and D are also incorrect as there is no specific dietary restriction related to doxazosin mesylate.
