1. Which electrolyte imbalance is common in patients receiving diuretics?

• A. Hypokalemia
• B. Hypercalcemia
• C. Hyponatremia
• D. Hypermagnesemia

Correct answer: A

Rationale: The correct answer is Hypokalemia. Diuretics, such as furosemide, commonly cause potassium loss in patients, leading to hypokalemia. This electrolyte imbalance should be closely monitored to prevent complications like cardiac arrhythmias. Hypercalcemia (Choice B) is not typically associated with diuretic use. Hyponatremia (Choice C) involves low sodium levels and can occur in conditions like syndrome of inappropriate antidiuretic hormone secretion (SIADH) but is not directly caused by diuretics. Hypermagnesemia (Choice D) is an excess of magnesium, usually not a common electrolyte imbalance induced by diuretics.

2. A healthcare professional is reviewing the laboratory data of a client who has diabetes mellitus. Which of the following laboratory tests is an indicator of long-term disease management?

• A. Postprandial blood glucose
• B. Glycosylated hemoglobin (HbA1c)
• C. Glucose tolerance test
• D. Fasting blood glucose

Correct answer: B

Rationale: Glycosylated hemoglobin (HbA1c) is the most accurate test for long-term management of blood glucose levels in individuals with diabetes mellitus. HbA1c reflects average blood glucose levels over the past 2-3 months, providing valuable information on the effectiveness of treatment and disease control. Postprandial blood glucose, glucose tolerance test, and fasting blood glucose are essential for monitoring blood glucose levels at specific times but do not offer the same insight into long-term disease management as HbA1c.

3. A nurse is assessing a client who is postoperative following a hip arthroplasty. Which of the following findings is the priority for the nurse to report?

• A. Heart rate of 90/min
• B. Blood pressure of 118/76 mm Hg
• C. Warmth and redness in the calf
• D. Pink-tinged urine

Correct answer: C

Rationale: The correct answer is C, warmth and redness in the calf. These symptoms may indicate a deep vein thrombosis (DVT), a serious complication following hip arthroplasty that requires immediate attention. A heart rate of 90/min and blood pressure of 118/76 mm Hg are within normal ranges for a postoperative client and do not indicate an urgent issue. Pink-tinged urine may suggest blood in the urine, which should be monitored but is not as critical as the potential DVT.

4. A nurse is preparing to administer dopamine hydrochloride at 4 mcg/kg/min for a client weighing 80 kg. How many mL/hr should the nurse set the IV infusion to deliver?

• A. 6 mL/hr
• B. 8 mL/hr
• C. 12 mL/hr
• D. 16 mL/hr

Correct answer: A

Rationale: To calculate the correct rate, you first need to convert the weight to micrograms: 4 mcg/kg/min * 80 kg = 320 mcg/min. Then, convert micrograms to milligrams: 320 mcg/min / 1000 = 0.32 mg/min. Next, calculate how many milligrams per hour: 0.32 mg/min * 60 min/hr = 19.2 mg/hr. Finally, determine the mL/hr rate by using the concentration provided: 19.2 mg/hr / 800 mg in 250 mL = 6 mL/hr. Therefore, the correct answer is 6 mL/hr. Choice B, 8 mL/hr, is incorrect as it does not reflect the accurate calculation based on the weight and drug concentration. Choices C and D, 12 mL/hr and 16 mL/hr, are also incorrect as they do not align with the correct calculation of the infusion rate for dopamine hydrochloride based on the client's weight and the medication concentration.

5. A client with a new diagnosis of hypertension is receiving teaching from a nurse. Which of the following statements by the client indicates an understanding of the teaching?

• A. I will check my blood pressure at least once a week.
• B. I will avoid eating foods high in potassium.
• C. I should exercise for 30 minutes at least 5 days a week.
• D. I will take my medication only when I feel dizzy.

Correct answer: C

Rationale: The correct answer is C. Regular exercise is an essential component in managing hypertension. Exercising for at least 30 minutes a day, at least 5 days a week, can help control blood pressure. Checking blood pressure regularly (choice A) is important, but not as indicative of understanding the teaching as the commitment to regular exercise. Avoiding foods high in potassium (choice B) is not a typical recommendation for managing hypertension. Taking medication only when feeling dizzy (choice D) is incorrect and potentially dangerous; medications should be taken as prescribed by the healthcare provider.
