HESI Fundamentals Study Guide Questions
Question 1 of 5
A client with a history of chronic renal failure is admitted with generalized edema. Which laboratory value should the LPN/LVN monitor to assess the client's fluid balance?
Correct Answer: C
Rationale: The correct answer is C, Serum albumin. In clients with chronic renal failure and generalized edema, monitoring serum albumin levels is crucial as it is a key indicator of fluid balance. Low serum albumin levels can contribute to edema formation due to decreased oncotic pressure, indicating fluid imbalance. Serum potassium (Choice A) is more related to kidney function and electrolyte balance in renal failure patients. Serum calcium (Choice B) is important for bone health but is not directly related to fluid balance. Serum sodium (Choice D) is more indicative of hydration status and electrolyte balance but may not directly reflect fluid balance in the context of chronic renal failure and edema.
Question 2 of 5
A client with osteoporosis is prescribed alendronate (Fosamax). What instruction should the LPN/LVN provide to the client?
Correct Answer: A
Rationale: The correct instruction for a client prescribed alendronate (Fosamax) is to take the medication with a full glass of water. Alendronate can cause irritation to the esophagus, so it is important to take it with a full glass of water and remain upright for at least 30 minutes after taking the medication to help prevent this irritation. Taking the medication at bedtime (choice B) may increase the risk of esophageal irritation as lying down can allow the medication to remain in the esophagus longer. Taking the medication with food (choice C) or on an empty stomach (choice D) can also interfere with the absorption of alendronate, reducing its effectiveness in treating osteoporosis.
Question 3 of 5
A client with a history of hypertension is prescribed a beta-blocker. Which side effect should the LPN/LVN monitor for in this client?
Correct Answer: C
Rationale: The correct side effect that the LPN/LVN should monitor for in a client prescribed a beta-blocker is bradycardia. Beta-blockers work by slowing down the heart rate, which can lead to bradycardia as a common side effect. Monitoring the client's heart rate is crucial, as bradycardia can be a serious condition. Choices A, B, and D are incorrect because increased appetite, dry mouth, and insomnia are not typically associated with beta-blockers. Increased appetite is more commonly linked to certain medications like corticosteroids, dry mouth can be a side effect of anticholinergic medications, and insomnia may be a side effect of stimulant medications.
Question 4 of 5
During an assessment, a nurse is evaluating the breath sounds of an adult client diagnosed with pneumonia. Which of the following actions should the nurse take?
Correct Answer: A
Rationale: When assessing breath sounds in a client with pneumonia, the nurse should follow a systematic pattern from side-to-side moving down the client's chest. This approach ensures a comprehensive evaluation of breath sounds across different lung fields. Asking the client to breathe in deeply through their nose (Choice B) is not necessary for assessing breath sounds. Instructing the client to sit upright with their head slightly tilted backward (Choice C) is not directly related to assessing breath sounds and may not be required. Placing the diaphragm of the stethoscope on the client's chest (Choice D) is not the correct technique for auscultating breath sounds, as the diaphragm should be used for this purpose.
Question 5 of 5
A client with a history of diabetes mellitus is experiencing polyuria, polydipsia, and polyphagia. What is the most important action for the LPN/LVN to take?
Correct Answer: A
Rationale: The most important action for the LPN/LVN to take when a client with a history of diabetes mellitus experiences symptoms of hyperglycemia such as polyuria, polydipsia, and polyphagia is to monitor the client's blood glucose level. This action helps assess the severity of hyperglycemia and guides further interventions. Encouraging the client to increase fluid intake (Choice B) may exacerbate the symptoms by further diluting the blood glucose concentration. Administering insulin as prescribed (Choice C) should be done based on the healthcare provider's orders and after assessing the blood glucose levels. Assessing the client's urine output (Choice D) is important but not the most immediate action needed in this scenario.
