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 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.

3. A nurse is administering metformin to a client with type 2 diabetes. Which of the following adverse effects should the nurse monitor for in this client?

• A. Diarrhea
• B. Hyperglycemia
• C. Hypoglycemia
• D. Lactic acidosis

Correct answer: D

Rationale: The correct answer is D, Lactic acidosis. Lactic acidosis is a rare but serious adverse effect of metformin use. Metformin is not known to cause hyperglycemia or hypoglycemia. Diarrhea is a common gastrointestinal side effect of metformin but is not as serious as lactic acidosis, which requires immediate medical attention.

4. A nurse is caring for a client receiving IV vancomycin. The nurse notes flushing of the client's neck and chest. Which of the following actions should the nurse take?

• A. Stop the infusion
• B. Document the findings as a harmless reaction
• C. Slow the infusion rate
• D. Administer diphenhydramine

Correct answer: C

Rationale: The correct action for the nurse to take when a client receiving IV vancomycin shows flushing of the neck and chest is to slow the infusion rate. Flushing is a common sign of Red Man Syndrome, which is associated with rapid infusions of vancomycin. Slowing down the infusion rate can help prevent further flushing and the development of Red Man Syndrome. Stopping the infusion (Choice A) may be too drastic if the symptoms are mild and can be managed by slowing the rate. Documenting the findings as a harmless reaction (Choice B) is incorrect because flushing should be addressed promptly to prevent complications. Administering diphenhydramine (Choice D) is not the initial or best intervention for flushing associated with vancomycin; slowing the infusion rate is the priority.

5. A nurse is preparing to administer nitroglycerin ointment to a client. Which of the following actions should the nurse take?

• A. Apply the ointment to the client's hairless chest
• B. Rub the ointment gently into the skin
• C. Cover the applied ointment with a transparent dressing
• D. Massage the ointment into the skin

Correct answer: A

Rationale: The correct action is to apply the nitroglycerin ointment to a hairless area of the client's chest, back, or upper arms. This allows for better absorption of the medication. Choice B is incorrect because rubbing the ointment gently into the skin may be appropriate, but the primary action is to ensure application on a hairless area. Choice C is incorrect as covering the ointment with a transparent dressing is not a standard practice for nitroglycerin ointment administration. Choice D is incorrect because massaging the ointment into the skin is not recommended, as it can alter absorption rates.
