Correct Answer: B

Rationale: Alcoholism places a client at risk for developing cirrhosis due to the liver damage caused by excessive alcohol consumption. Type I diabetes, leukemia, and glaucoma are not directly associated with cirrhosis. While diabetes can lead to other health complications, it does not directly cause cirrhosis. Leukemia is a type of blood cancer that does not affect the liver in a way that leads to cirrhosis. Glaucoma is an eye condition that has no direct link to cirrhosis.

Correct Answer: D

Rationale: The correct answer is Morton's neuroma. Morton's neuroma is a small mass or tumor in a digital nerve of the foot, causing pain and difficulty walking. Hallux valgus is commonly known as a bunion, involving a bony bump at the base of the big toe. Hammertoe is a condition where one toe is bent abnormally at the middle joint, resembling a hammer. Plantar fasciitis is characterized by pain and inflammation in the arch of the foot, not by a mass causing difficulty walking. Therefore, options A, B, and C are incorrect as they do not describe a mass in the foot leading to difficulty walking, unlike Morton's neuroma.

Correct Answer: A

Rationale: Erythropoietin is used to stimulate red blood cell production in clients with renal failure. To effectively increase red blood cell production, adequate levels of iron, folic acid, and B12 are necessary. These nutrients play crucial roles in erythropoiesis. Choices B, an increase in protein in the diet, is not directly related to enhanced erythropoiesis and can potentially worsen uremia. Choices C and D, vitamins A and C, and an increase in calcium in the diet, are not directly involved in red blood cell production and are not essential in this context.

Correct Answer: C

Rationale: The priority intervention for preventing respiratory complications in a client with advanced COPD who underwent gallbladder surgery is to get the client out of bed 4 times daily. This helps prevent pooling of secretions in the lungs and promotes better lung expansion. Incentive spirometry, coughing, and deep breathing are essential interventions; however, they should be performed more frequently, ideally every 1 to 2 hours, rather than every 4 hours or 4 times daily. Giving oxygen at 4 L/minute could potentially decrease the client's respiratory drive, which is not the priority in this case.

Correct Answer: B

Rationale: Zofran is a serotonin antagonist that can be used to relieve nausea and vomiting. Ondansetron (Zofran) works by blocking serotonin receptors in the chemoreceptor trigger zone (CTZ) and the gastrointestinal tract. This action helps reduce nausea and vomiting. Metoclopramide (Reglan) works as a dopamine antagonist and also has prokinetic effects, making it effective for different conditions. Hydroxyzine (Vistaril) is an antihistamine with antiemetic properties, but it does not act as a serotonin antagonist. Prochlorperazine (Compazine) is a dopamine antagonist that is also used to treat nausea and vomiting, but not as a serotonin antagonist like ondansetron.
