HESI RN Medical Surgical Practice Exam
1. A client is vomiting. For which acid-base imbalance does the nurse assess the client?
- A. Metabolic acidosis
- B. Metabolic alkalosis
- C. Respiratory acidosis
- D. Respiratory alkalosis
Correct answer: B
Rationale: In a client who is vomiting, the loss of gastric fluid containing hydrochloric acid can lead to metabolic alkalosis. Metabolic alkalosis is caused by the loss of acids such as hydrochloric acid from the body. Therefore, in this scenario, the nurse should assess the client for metabolic alkalosis. Choices A, C, and D are incorrect because vomiting does not typically lead to metabolic acidosis, respiratory acidosis, or respiratory alkalosis.
2. A community health nurse is planning a program to reduce the incidence of heart disease in the community. Which intervention should the nurse prioritize?
- A. Distributing educational materials on heart-healthy diets
- B. Organizing free cholesterol screenings
- C. Holding workshops on stress management
- D. Partnering with local gyms to offer fitness classes
Correct answer: B
Rationale: The correct answer is B: Organizing free cholesterol screenings. This intervention is crucial because it helps identify individuals at risk for heart disease by assessing their cholesterol levels. High cholesterol is a significant risk factor for heart disease, and identifying it early can lead to timely interventions and medical care. Choices A, C, and D, while beneficial for overall health, may not directly address the specific risk factor of high cholesterol associated with heart disease. Distributing educational materials on heart-healthy diets (A) could be helpful in preventing heart disease, but identifying individuals already at risk is a more urgent need. Holding workshops on stress management (C) and partnering with local gyms for fitness classes (D) are important for overall health promotion but may not target the specific risk factor of high cholesterol as directly as organizing cholesterol screenings.
3. A teenager who has lost 20 pounds in the last three months is admitted to the hospital with hypotension and tachycardia. The client reports irregular menses and hair loss. Which intervention is most important for the nurse to include in the client plan of care?
- A. Implement behavior modification therapy.
- B. Initiate caloric and nutritional therapy.
- C. Evaluate the client for low self-esteem.
- D. Record daily weights and graph trends.
Correct answer: B
Rationale: Initiating caloric and nutritional therapy is the most important intervention for this client due to the significant weight loss and presenting symptoms of hypotension, tachycardia, irregular menses, and hair loss. This intervention aims to address the physical effects of malnutrition and support the client's overall health. Behavior modification therapy (Choice A) may be beneficial in the long term to address underlying issues, but addressing the immediate nutritional needs is a priority. Evaluating the client for low self-esteem (Choice C) is important for holistic care but addressing the physical health concerns takes precedence. Recording daily weights and graphing trends (Choice D) is essential for monitoring progress but does not address the urgent need for nutritional support in this acute situation.
4. The nurse is providing discharge teaching to a client with gastroesophageal reflux disease (GERD). Which instruction should the nurse include in the teaching?
- A. Increase fluid intake with meals
- B. Avoid lying down for at least 30 minutes after eating
- C. Eat small, frequent meals throughout the day
- D. Consume spicy foods in moderation
Correct answer: C
Rationale: The correct instruction for the nurse to include in the teaching for a client with GERD is to eat small, frequent meals throughout the day. This recommendation helps reduce symptoms by preventing the stomach from becoming overly full, which can increase pressure on the lower esophageal sphincter and lead to acid reflux. Choices A, B, and D are incorrect because increasing fluid intake with meals can exacerbate GERD symptoms, lying down after eating can worsen reflux, and consuming spicy foods can trigger acid reflux in individuals with GERD.
5. A client with diabetes mellitus who is taking NPH insulin (Humulin N) in the evening is most likely to become hypoglycemic shortly after midnight because this insulin peaks in 6 to 8 hours. What intervention should the nurse recommend to help prevent hypoglycemia while the client is sleeping?
- A. Eat a bedtime snack.
- B. Avoid physical activity.
- C. Take half the usual dose of insulin.
- D. Discontinue insulin until the next meal.
Correct answer: A
Rationale: Eating a bedtime snack is the most appropriate intervention to prevent hypoglycemia during the night when NPH insulin peaks. This snack helps maintain blood glucose levels and counteracts the risk of hypoglycemia. Avoiding physical activity is not recommended as it can further lower blood sugar levels. Taking half the usual dose of insulin can lead to inadequate control of blood sugar levels. Discontinuing insulin until the next meal can result in uncontrolled hyperglycemia, especially during the peak action of NPH insulin.
