LPN Pharmacology Assessment A
1. The client with a diagnosis of heart failure is receiving furosemide (Lasix). Which laboratory value is most important for the nurse to monitor?
- A. Blood glucose
- B. Serum sodium
- C. Serum potassium
- D. Blood urea nitrogen (BUN)
Correct answer: C
Rationale: The correct answer is C: Serum potassium. When a client is receiving furosemide, a loop diuretic, it can lead to potassium loss. Monitoring the serum potassium levels is crucial to prevent life-threatening complications such as cardiac arrhythmias. Blood glucose (Choice A) is not directly impacted by furosemide. Serum sodium (Choice B) may be affected, but monitoring potassium is more critical due to the risk of arrhythmias. Blood urea nitrogen (BUN) (Choice D) is important for assessing kidney function but is not the most crucial value to monitor in a client taking furosemide.
2. Two amino acids are chemically joined by a:
- A. double bond.
- B. hydrogen bond.
- C. carboxyl bond.
- D. peptide bond.
Correct answer: D
Rationale: The correct answer is D, peptide bond. A peptide bond is formed through a dehydration synthesis reaction between the amine group of one amino acid and the carboxyl group of another amino acid. This bond is crucial in protein synthesis. Choices A, B, and C are incorrect. A double bond involves sharing two pairs of electrons, a hydrogen bond is a weak attraction between a hydrogen atom and an electronegative atom, and a carboxyl bond is not a common term in biochemistry.
3. What is the role of a nurse in managing a patient with acute kidney injury (AKI)?
- A. Monitor urine output and electrolyte levels
- B. Administer diuretics and restrict potassium
- C. Provide dietary education and monitor fluid intake
- D. Administer antibiotics and check for dehydration
Correct answer: A
Rationale: The correct answer is A: 'Monitor urine output and electrolyte levels.' In managing a patient with acute kidney injury (AKI), it is crucial for the nurse to monitor urine output and electrolyte levels to assess kidney function and the patient's fluid and electrolyte balance. This monitoring helps in early detection of any worsening kidney function or electrolyte imbalances. Choice B is incorrect because administering diuretics and restricting potassium may not be appropriate for all AKI patients and should be done under the direction of a healthcare provider. Choice C is also incorrect as providing dietary education and monitoring fluid intake are important but do not directly address the immediate management of AKI. Choice D is incorrect as administering antibiotics and checking for dehydration are not primary interventions for managing AKI; antibiotics are only given if there is an infection contributing to AKI, and dehydration should be managed but is not the primary role of the nurse in AKI management.
4. Which intervention is essential when caring for a client with heart failure on fluid restriction?
- A. Encourage the client to drink water throughout the day
- B. Monitor the client's weight daily to assess fluid balance
- C. Limit fluid intake during meals
- D. Weigh the client once a week to assess fluid balance
Correct answer: B
Rationale: The correct answer is B: 'Monitor the client's weight daily to assess fluid balance.' When caring for a client with heart failure on fluid restriction, it is essential to monitor their weight daily to evaluate fluid balance accurately. This helps healthcare providers assess if the client is retaining excess fluid, a common issue in heart failure. Choices A, C, and D are incorrect. Encouraging the client to drink water throughout the day contradicts fluid restriction. Limiting fluid intake during meals may not provide a comprehensive assessment of fluid balance, and weighing the client once a week is not frequent enough to detect rapid changes in fluid status that could worsen heart failure symptoms.
5. The healthcare provider is planning care for a non-potty-trained child with nephrotic syndrome. Which intervention provides the best means of determining fluid retention?
- A. Weigh the child daily.
- B. Observe the lower extremities for pitting edema.
- C. Measure the child's abdominal girth weekly.
- D. Weigh the child's wet diapers.
Correct answer: A
Rationale: Daily weighing is the most accurate method to monitor fluid retention in a child with nephrotic syndrome. Changes in weight can indicate fluid retention or loss, which is crucial in managing nephrotic syndrome. Observing for pitting edema and measuring abdominal girth are also important assessments, but daily weighing provides more immediate and precise information about fluid status.
