Nursing Elites

1. A client with a family history of polycystic kidney disease (PKD is being assessed by a nurse. For which clinical manifestations should the nurse assess? (Select all that apply.)

• A. Nocturia
• B. Flank pain
• C. Increased abdominal girth
• D. B & C

Correct answer: D

Rationale: Clients with PKD commonly present with flank pain and increased abdominal girth due to abdominal distention caused by cysts. Bloody urine is also a common symptom due to tissue damage from PKD. Nocturia and dysuria are not typical manifestations of PKD. Constipation is not directly associated with PKD. Therefore, the correct choices are flank pain and increased abdominal girth, making option D the correct answer.

2. Which lab result would be most indicative of renal failure?

• A. Elevated creatinine levels.
• B. Low potassium levels.
• C. Low calcium levels.
• D. High sodium levels.

Correct answer: A

Rationale: The correct answer is A: Elevated creatinine levels. Creatinine is a waste product that is normally filtered by the kidneys. Elevated creatinine levels indicate impaired kidney function, which is commonly seen in renal failure. Choice B, low potassium levels, is not typically associated with renal failure. In fact, renal failure is more likely to cause high potassium levels due to the kidneys' inability to excrete potassium effectively. Choice C, low calcium levels, are not directly indicative of renal failure. Renal failure can lead to disturbances in calcium levels, but low calcium levels alone are not a specific marker for renal failure. Choice D, high sodium levels, are also not typically associated with renal failure. In renal failure, there may be disturbances in sodium levels, but high sodium levels alone are not a direct indicator of renal failure.

3. A patient is taking a thiazide diuretic and reports anorexia and fatigue. The nurse suspects which electrolyte imbalance in this patient?

• A. Hypercalcemia
• B. Hypocalcemia
• C. Hyperkalemia
• D. Hypokalemia

Correct answer: D

Rationale: The correct answer is D: Hypokalemia. Thiazide diuretics lead to potassium loss, potentially causing hypokalemia. Anorexia and fatigue are common manifestations of hypokalemia. Hypercalcemia (choice A) and hypocalcemia (choice B) are not directly associated with thiazide diuretics. Hyperkalemia (choice C) is less likely than hypokalemia to be caused by thiazide diuretics.

4. 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.

5. A child who weighs 10 kg will begin taking oral trimethoprim-sulfamethoxazole (TMP-SMX). The liquid preparation contains 40 mg of TMP and 200 mg of SMX per 5 mL. The nurse determines that the child’s dose should be 8 mg of TMP and 40 mg of SMX/kg/day divided into two doses. Which order for this child is correct?

• A. 5 mL PO BID
• B. 5 mL PO daily
• C. 10 mL PO BID
• D. 10 mL PO daily

Correct answer: A

Rationale: The correct answer is A: '5 mL PO BID.' To calculate the child’s daily dose requirement, you multiply the child's weight (10 kg) by the prescribed dosage per kg, which is 8 mg for TMP and 40 mg for SMX. This results in a total daily requirement of 80 mg of TMP and 400 mg of SMX. To divide this into two doses, each dose should contain half of the total daily requirement, which is 40 mg TMP and 200 mg SMX. Since the liquid preparation contains 40 mg of TMP and 200 mg of SMX per 5 mL, the correct dose per administration is 5 mL. Therefore, 5 mL PO BID is the correct order. Choice B, '5 mL PO daily,' is incorrect as the total daily dose needs to be divided into two doses. Choices C and D, '10 mL PO BID' and '10 mL PO daily,' respectively, are incorrect as they do not align with the calculated dosage requirements based on the child's weight and the prescribed dosage per kg.
