1. A client is on a mechanical ventilator. Which client response indicates that the neuromuscular blocker tubocurarine chloride (Tubarine) is effective?

Correct answer: A

Rationale: The correct answer is A. Tubocurarine chloride is a neuromuscular blocker that works by causing paralysis of skeletal muscles. Therefore, if the client's extremities are paralyzed, it indicates that the medication is effective in achieving the desired muscle relaxation necessary for mechanical ventilation. Choices B and C are incorrect as they suggest muscle activity, which would not be expected with the administration of a neuromuscular blocker. Choice D is unrelated to the effectiveness of tubocurarine chloride.

2. A recently widowed middle-aged female client presents to the psychiatric clinic for evaluation and tells the nurse that she has 'little reason to live.' She describes one previous suicidal gesture and admits to having a gun in her home. To maintain the client's confidentiality and to help ensure her safety, which action is best for the nurse to implement?

Correct answer: C

Rationale: In this scenario, it is crucial to maintain the client's confidentiality while ensuring her safety. Contacting a person chosen by the client to remove the weapon from her home is the best course of action. This approach respects the client's autonomy and helps reduce the risk of harm without involving external authorities unnecessarily.

3. What is the most likely diagnosis in a 30-year-old woman with right upper quadrant pain, fever, and jaundice, along with elevated white blood cell count and bilirubin levels?

Correct answer: C

Rationale: The combination of right upper quadrant pain, fever, jaundice, elevated white blood cell count, and bilirubin levels is classic for acute cholangitis, which is an infection of the bile ducts. Acute hepatitis typically presents with other liver function abnormalities, while acute cholecystitis is characterized by gallbladder inflammation. Pancreatic cancer would not typically present with these specific symptoms and lab findings.

4. A patient with severe anemia is prescribed erythropoietin. What is the primary action of this medication?

Correct answer: C

Rationale: Erythropoietin is a hormone that primarily stimulates the bone marrow to produce more red blood cells. By increasing red blood cell production, erythropoietin helps to improve oxygen delivery to tissues, which is essential in managing anemia. Choices A, B, and D are incorrect because erythropoietin specifically targets red blood cell production and does not have a direct effect on white blood cells, platelets, or clotting factors.

5. A patient with deep vein thrombosis (DVT) is prescribed warfarin. Which dietary instruction should the nurse provide?

Correct answer: A

Rationale: Patients on warfarin should avoid foods high in vitamin K because vitamin K can interfere with the anticoagulant effect of the medication. Warfarin works by inhibiting vitamin K-dependent clotting factors, so consuming large amounts of vitamin K-rich foods may decrease the effectiveness of the medication. Choices B, C, and D are incorrect. Increasing intake of dairy products, limiting citrus fruits, or avoiding high-sodium foods are not directly related to the mechanism of action of warfarin or its dietary considerations.
