The nurse is caring for a client admitted with Class III/IV Pulmonary Hypertension. The nurse explains to the client that Lanoxin is being administered to the client in order to:

Correct Answer: B

Rationale: The correct answer is to improve right ventricular function. Lanoxin, also known as digoxin, is a cardiac glycoside that works by slowing the heart rate and increasing myocardial contractility, especially in the ventricles. This action helps improve the efficiency of the heart's pumping function, particularly the right ventricle in conditions like pulmonary hypertension. Choice A, managing peripheral edema, is not directly related to Lanoxin's mechanism of action. Choice C, increasing pulmonary pressure, is incorrect as Lanoxin is not used to increase pressure in the pulmonary circulation. Choice D, constricting the pulmonary vessels, is incorrect as Lanoxin does not cause vasoconstriction in the pulmonary vessels but rather acts on the heart's contractility.

Correct Answer: B

Rationale: A family history of colon polyps and/or colon cancer is a significant risk factor for developing colon cancer. Individuals with a family history are more likely to develop colon cancer due to genetic predisposition. While other factors like irritable bowel syndrome, cirrhosis of the liver, and history of colon surgery may contribute to an increased risk of colon cancer, having a family history of colon polyps is the highest risk factor. Irritable bowel syndrome does not directly increase the risk of colon cancer. Cirrhosis of the liver is associated with liver cancer rather than colon cancer. A history of colon surgery may reduce the risk of colon cancer in some cases by removing precancerous polyps.

Correct Answer: D

Rationale: The correct answer is Albuterol (Atrovent) because it is a rapid-acting bronchodilator, essential for a client experiencing wheezing and difficulty breathing. Albuterol acts quickly, dilating the airways and providing immediate relief in cases of respiratory distress. Fluticasone (Flovent) and Salmeterol (Serevent) are maintenance medications for long-term asthma control, not suitable for acute situations described. Theophylline (Theodur) is a bronchodilator but with a slower onset compared to Albuterol, making it less appropriate for a client in immediate distress.

Correct Answer: A

Rationale: The correct answer is 'Weight gain.' When assessing for signs and symptoms of active TB infection, weight loss is typically observed rather than weight gain. Other common signs and symptoms include fatigue, bloody sputum, and diaphoresis during sleep. Fatigue, bloody sputum, and diaphoresis during sleep are all associated with active TB infection. Weight gain is not typically seen in active TB; instead, patients usually experience weight loss due to the impact of the infection on their overall health.

Correct Answer: A

Rationale: After applying oxygen using bi-nasal prongs to a client with chest pain, it is essential for the nurse to post signs indicating that oxygen is in use on the client's door and in their room. This safety precaution alerts healthcare providers and visitors that the client is receiving oxygen therapy, reducing the risk of accidents or misunderstandings. Choice A is incorrect because instructing the client to take slow deep breaths is not the appropriate intervention after applying oxygen. Choice C suggests applying Vaseline and gauze, which is unnecessary and not a standard practice. Choice D advising the client to hyperextend the neck, take deep breaths, and cough is not indicated after applying oxygen therapy and could potentially be harmful.

Correct Answer: A

Rationale: The correct answer is a fresh apple. After a thyroidectomy, it is important to avoid hard and crunchy foods like apples due to the proximity of the esophagus to the surgical site. Apples can be difficult to chew and swallow, posing a risk of injury or discomfort to the patient. V8 juice, mustard greens, and ice cream are softer options that would be more suitable for a client recovering from thyroidectomy.

Correct Answer: C

Rationale: Based on the client's unresponsiveness, fruity breath smell, and the presence of diabetes, the nurse can infer that the client is experiencing diabetic ketoacidosis (DKA). DKA is a complication of diabetes characterized by the accumulation of ketones in the body, leading to metabolic acidosis. The fruity breath smell is due to the presence of ketones. Therefore, the correct acid-base imbalance in this scenario is metabolic acidosis. Choice A, respiratory acidosis, is incorrect because the scenario does not provide evidence of primary respiratory dysfunction. Choice B, respiratory alkalosis, is incorrect as the client's condition does not align with the typical causes and symptoms of respiratory alkalosis. Choice D, metabolic alkalosis, is incorrect as the symptoms and history provided do not suggest a state of metabolic alkalosis.

Correct Answer: D

Rationale: The correct answer is to 'Increase fiber.' In hypothyroidism, clients often experience constipation due to decreased metabolic rate. Increasing fiber in the diet can help alleviate constipation. Choice A, 'Increase carbohydrate intake,' is incorrect as there is no specific need to increase carbohydrate intake in hypothyroidism. Choice B, 'Increase fluid intake,' is not directly related to managing hypothyroidism, although adequate hydration is generally important for overall health. Choice C, 'Avoid shellfish,' is commonly associated with hyperthyroidism due to its iodine content, not hypothyroidism.

Correct Answer: B

Rationale: The correct answer is 'Fat-soluble vitamins.' Vitamin B, not Vitamin D, is crucial in preventing peripheral neuritis in individuals with alcohol abuse. Vitamin B deficiency, particularly B1 (thiamine), is commonly associated with peripheral neuritis in alcoholics. Therefore, choices A, C, and D are incorrect. Vitamin D is not directly related to peripheral neuritis, and potassium deficiency typically presents with different symptoms.
