HESI LPN
Practice HESI Fundamentals Exam
1. A client with diabetes mellitus is being taught by a nurse about mixing regular and NPH insulin. Which of the following statements by the client indicates an understanding of the teaching?
- A. I should roll the NPH vial between my hands before drawing it up.
- B. I should draw up the NPH insulin before the regular insulin.
- C. I should inject air into the vial of regular insulin first.
- D. I should wait 10 minutes after mixing the insulin to inject it.
Correct answer: A
Rationale: The correct answer is A. Rolling the NPH vial between the hands before drawing it up ensures proper mixing of the insulin. Choice B is incorrect because regular insulin should be drawn up first to avoid contamination. Choice C is incorrect as injecting air into the vial of regular insulin is not necessary. Choice D is incorrect as there is no need to wait 10 minutes after mixing the insulin before injecting it.
2. What should be the priority action when caring for a child with acute laryngotracheobronchitis?
- A. Initiate measures to reduce fever.
- B. Ensure delivery of humidified oxygen.
- C. Provide support to reduce apprehension.
- D. Continually assess the respiratory status.
Correct answer: D
Rationale: The priority action when caring for a child with acute laryngotracheobronchitis is to continually assess the respiratory status (Option D). Acute laryngotracheobronchitis can potentially lead to respiratory distress, making continuous monitoring crucial to identify early signs of deterioration and intervene promptly. While options A, B, and C are also important aspects of care, they do not take precedence over respiratory assessment in this critical situation. Initiating measures to reduce fever (Option A), ensuring oxygen delivery (Option B), and providing emotional support (Option C) are all significant interventions, but without ongoing assessment of respiratory status, there is a risk of missing potential respiratory deterioration.
3. Which of the following components of nutrition has a primary function of helping with tissue growth and repair?
- A. Vitamin D
- B. Vitamin E
- C. Protein
- D. Fat
Correct answer: C
Rationale: Protein is the correct answer as it is essential for tissue growth and repair. Proteins are composed of amino acids, the building blocks of body tissues. While vitamins D and E have important roles in the body, they are not primarily responsible for tissue growth and repair. Fats are crucial for various bodily functions, like providing energy, but they are not the primary component involved in tissue growth and repair.
4. A client with a history of seizures is prescribed phenytoin (Dilantin). What side effect should the healthcare provider report immediately?
- A. Increased appetite
- B. Dry mouth
- C. Nausea and vomiting
- D. Gingival hyperplasia
Correct answer: D
Rationale: Gingival hyperplasia is a significant side effect associated with phenytoin therapy. It is characterized by an overgrowth of gum tissue, which can lead to issues such as difficulty in speaking, eating, and maintaining proper oral hygiene. This condition can progress rapidly and may require immediate intervention by the healthcare provider to prevent further complications. Increased appetite, dry mouth, and nausea/vomiting are common side effects of various medications, but they are not as urgent or serious as gingival hyperplasia in a client taking phenytoin.
5. A client with diabetes mellitus type 2 is prescribed sitagliptin. The nurse should include which instruction in the client's teaching plan?
- A. Take this medication with meals.
- B. Avoid alcohol while taking this medication.
- C. Take this medication on an empty stomach.
- D. Report any signs of pancreatitis to the healthcare provider.
Correct answer: D
Rationale: The correct instruction to include in the teaching plan for a client prescribed sitagliptin is to report any signs of pancreatitis to the healthcare provider. Sitagliptin is generally taken with meals to reduce gastrointestinal side effects. Therefore, choice A, 'Take this medication with meals,' is incorrect. Sitagliptin does not have specific interactions with alcohol, so there is no need to advise the client to avoid alcohol, making choice B incorrect. Taking sitagliptin on an empty stomach is not recommended, so choice C is also incorrect. Pancreatitis is a rare but serious side effect of sitagliptin, so it is crucial for the client to report any signs or symptoms to their healthcare provider promptly.
