A healthcare professional is reviewing the results of serum laboratory studies of a client with suspected hepatitis. Which increased parameter is interpreted as the most specific indicator of this disease?
- A. Hemoglobin
- B. Serum bilirubin
- C. Blood urea nitrogen (BUN)
- D. Erythrocyte sedimentation rate (ESR)
Correct Answer: B
Rationale: Serum bilirubin is the most specific indicator of hepatitis as it reflects liver dysfunction. Hemoglobin, blood urea nitrogen (BUN), and erythrocyte sedimentation rate (ESR) are not specific to hepatitis. Hemoglobin measures the oxygen-carrying capacity of red blood cells, BUN evaluates kidney function, and ESR is a nonspecific marker of inflammation or infection.

The nurse is preparing to administer doses of hydrochlorothiazide (HydroDIURIL) and digoxin (Lanoxin) to a patient who has heart failure. The patient reports having blurred vision. The nurse notes a heart rate of 60 beats per minute and a blood pressure of 140/78 mm Hg. Which action will the nurse take?
- A. Administer the medications and request an order for serum electrolytes.
- B. Give both medications and evaluate serum blood glucose frequently.
- C. Hold the digoxin and notify the provider.
- D. Hold the hydrochlorothiazide and notify the provider.
Correct Answer: C
Rationale: In this scenario, the patient is experiencing symptoms of digoxin toxicity, such as blurred vision and bradycardia. When thiazide diuretics like hydrochlorothiazide are taken with digoxin, the patient is at risk of digoxin toxicity due to the potential for thiazides to cause hypokalemia. Therefore, the correct action for the nurse to take is to hold the digoxin and notify the provider. Administering the medications without addressing the potential toxicity could worsen the patient's condition. Requesting serum electrolytes (Choice A) may be necessary but holding the digoxin takes priority. Evaluating serum blood glucose (Choice B) is not relevant to the current situation. Holding hydrochlorothiazide (Choice D) is not the best option as the primary concern is the digoxin toxicity that needs to be addressed promptly.
A client with a history of calcium phosphate urinary stones is being taught by a nurse. Which statements should the nurse include in this client's dietary teaching? (Select all that apply.)
- A. Limit your intake of food high in animal protein.
- B. Read food labels to help minimize your sodium intake.
- C. A and B
- D. Reduce your intake of milk and other dairy products.
Correct Answer: C
Rationale: For a client with a history of calcium phosphate urinary stones, it is essential to limit the intake of foods high in animal protein to prevent the formation of stones. Additionally, reducing sodium intake is crucial as high sodium levels can contribute to stone formation. Therefore, choices A and B are correct. Choice D, which suggests reducing intake of milk and other dairy products, is not specifically recommended for calcium phosphate stones. Clients with calcium phosphate stones should focus on limiting animal protein, sodium, and calcium intake. Choices A and B address these dietary modifications, making them the correct options for this client. Choices D, which is not directly related to calcium phosphate stones, is incorrect.
A middle-aged female client with diabetes mellitus is being treated for the third episode of acute pyelonephritis in the past year. The client asks, 'What can I do to help prevent these infections?' How should the nurse respond?
- A. Test your urine daily for the presence of ketone bodies and proteins.
- B. Use tampons rather than sanitary napkins during your menstrual period.
- C. Drink more water and empty your bladder more frequently during the day.
- D. Keep your hemoglobin A1c under 9% by controlling your blood sugar levels.
Correct Answer: C
Rationale: The correct answer is C. Clients with long-standing diabetes mellitus are at risk for pyelonephritis due to various reasons. Elevated blood glucose levels in diabetes can lead to glucose spilling into the urine, altering the pH and creating a conducive environment for bacterial growth. Neuropathy associated with diabetes can reduce bladder tone and diminish the sensation of bladder fullness, resulting in less frequent voiding and increased risk of stasis and bacterial overgrowth. Increasing fluid intake, particularly water, and voiding regularly can help prevent stasis and microbial overgrowth. Testing urine for ketones and proteins or using tampons instead of sanitary napkins are not effective strategies for preventing pyelonephritis. Keeping the hemoglobin A1c levels below 9% is crucial for managing diabetes, but it alone does not directly prevent pyelonephritis.
A client who has undergone pleural biopsy is being monitored by a nurse. Which finding indicates a potential complication for the client?
- A. Warm, dry skin
- B. Mild pain at the biopsy site
- C. Complaints of shortness of breath
- D. Capillary refill time of less than 3 seconds
Correct Answer: C
Rationale: Complaints of shortness of breath are a concerning finding post-pleural biopsy, as they may indicate a complication such as a pneumothorax or hemothorax. Shortness of breath can be a sign of respiratory distress that requires immediate attention. Warm, dry skin, mild pain at the biopsy site, and a capillary refill time of less than 3 seconds are not typically associated with immediate complications following a pleural biopsy. Warm, dry skin may be a normal finding, mild pain can be expected at the biopsy site, and a capillary refill time of less than 3 seconds is within normal limits.
A client with histoplasmosis has the following arterial blood gas (ABG) results: pH 7.30, PCO2 58 mm Hg, PO2 75 mm Hg, HCO3 27 mEq/L. Which of the following acid-base disturbances does the nurse recognize in these results?
- A. Metabolic acidosis
- B. Metabolic alkalosis
- C. Respiratory acidosis
- D. Respiratory alkalosis
Correct Answer: A
Rationale: The client's ABG results show a low pH (acidosis) and an elevated PCO2, indicating respiratory acidosis. In respiratory acidosis, there is inadequate excretion of CO2, leading to increased PCO2 levels and a decrease in pH. Therefore, the correct answer is 'Metabolic acidosis'. Choices B, C, and D are incorrect. Metabolic alkalosis is characterized by elevated pH and bicarbonate levels. Respiratory acidosis involves low pH and high PCO2 levels, as seen in this case. Respiratory alkalosis is associated with high pH and low PCO2 levels.
