Pharmacology HESI 55 Questions 2023
1. The patient is prescribed cimetidine (Tagamet) orally. What should the nurse consider about administering this drug?
- A. Administer the drug with the first bite of food
- B. Administer the drug immediately after meals
- C. Administer the drug 30 minutes after meals
- D. Administer the drug 30 minutes before meals
Correct answer: D
Rationale: Cimetidine is best absorbed when taken 30 minutes before meals to decrease stomach acid. Administering it before meals allows for optimal absorption and effectiveness of the medication. Choices A, B, and C are incorrect because administering cimetidine with food, immediately after meals, or 30 minutes after meals may not provide the best conditions for absorption. Taking it before meals ensures that the drug is absorbed properly and can exert its intended effects.
2. When documenting client care, which of the following abbreviations should be used?
- A. SS for sliding scale
- B. BRP for bathroom privileges
- C. OJ for orange juice
- D. SQ for subcutaneous
Correct answer: B
Rationale: When documenting client care, it is crucial to use standardized abbreviations to ensure clear communication and prevent misunderstandings. BRP for bathroom privileges is a recognized and commonly used abbreviation in healthcare settings. Choice A, SS for sliding scale, is not a standard abbreviation and can lead to confusion as it could be mistaken for other meanings. Choice C, OJ for orange juice, is informal and may not be universally understood in a healthcare context. Choice D, SQ for subcutaneous, is a valid abbreviation but may not be as relevant in the context of documenting client care compared to BRP, which is more specific and widely accepted.
3. A 6-year-old child with a diagnosis of juvenile idiopathic arthritis (JIA) is being discharged. What should the nurse include in the discharge teaching?
- A. Encourage participation in physical activity
- B. Provide a high-calorie diet
- C. Provide a low-sodium diet
- D. Administer intravenous fluids
Correct answer: A
Rationale: Encouraging regular physical activity is essential in managing symptoms and improving joint function in juvenile idiopathic arthritis. Physical activity helps maintain joint mobility, muscle strength, and overall function. Providing a high-calorie diet may not be necessary unless there are specific concerns about the child's nutritional status. A low-sodium diet is not typically a priority in the management of JIA unless the child has comorbid conditions requiring sodium restriction. Administering intravenous fluids is not a standard discharge teaching for JIA unless there are specific medical indications necessitating it.
4. Which nursing intervention provides the most support to the parents of an infant with an obvious physical anomaly?
- A. Encourage them to express their concerns.
- B. Discourage them from talking about their baby.
- C. Assure them not to worry because the anomaly can be repaired.
- D. Show them postoperative photographs of infants who had a similar anomaly.
Correct answer: A
Rationale: Encouraging parents to express their concerns is the most supportive intervention because it allows them to process their emotions and provides them with an opportunity to share their fears, anxieties, and questions. This open communication helps the nurse to offer appropriate support, education, and reassurance. Discouraging parents from talking about their baby (Choice B) can hinder their emotional expression and prevent them from seeking necessary information and support. Assuring parents not to worry (Choice C) may invalidate their feelings and minimize the significance of their concerns. Showing postoperative photographs (Choice D) may not be appropriate at this stage as parents need emotional support and education about the current situation before focusing on postoperative outcomes.
5. What is the primary cause of diabetic ketoacidosis (DKA)?
- A. Insulin deficiency
- B. Overhydration
- C. Excess carbohydrate intake
- D. Excess insulin
Correct answer: A
Rationale: The correct answer is A: Insulin deficiency. Diabetic ketoacidosis occurs due to a severe lack of insulin, causing the body to break down fat for energy, leading to the production of ketones and acidification of the blood. Option B, Overhydration, is incorrect as DKA is characterized by dehydration rather than overhydration. Option C, Excess carbohydrate intake, is incorrect because while high blood sugar levels can contribute to DKA, the primary cause is insulin deficiency. Option D, Excess insulin, is also incorrect as DKA is not caused by an excess of insulin but rather by a lack of it.
