1. 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.

2. Prior to administering tissue plasminogen activator (t-PA), the nurse should assess the client for which of the following contraindications to administering the drug?

• A. Age over 60 years.
• B. History of cerebral hemorrhage.
• C. History of heart failure.
• D. Cigarette smoking.

Correct answer: B

Rationale: The correct answer is B: History of cerebral hemorrhage. A history of cerebral hemorrhage is a contraindication to t-PA administration because of the increased risk of bleeding. Choices A, C, and D are incorrect. Age over 60 years is not a contraindication for t-PA administration. While older age may pose some risks, it is not an absolute contraindication. History of heart failure is not a direct contraindication to t-PA administration. Cigarette smoking, while a risk factor for cardiovascular disease, is not a specific contraindication for t-PA administration.

3. An adult female client has undergone a routine health screening in the clinic. Which of the following values indicates to the nurse who receives the report of the client’s laboratory work that the client’s hematocrit is normal?

• A. 10%
• B. 22%
• C. 30%
• D. 43%

Correct answer: D

Rationale: The normal hematocrit for an adult female client ranges from 35% to 47%. A hematocrit value of 43% falls within this normal range, indicating normal levels of red blood cells. Choices A, B, and C are low hematocrit values and are considered below the normal range for adult females, signifying potential anemia or other health issues.

4. What is the primary purpose of administering anticoagulants to a patient with atrial fibrillation?

• A. To reduce blood pressure.
• B. To prevent clot formation.
• C. To prevent arrhythmias.
• D. To reduce inflammation.

Correct answer: B

Rationale: The primary purpose of administering anticoagulants to a patient with atrial fibrillation is to prevent clot formation. Patients with atrial fibrillation are at an increased risk of forming blood clots in the heart, which can lead to stroke if they travel to the brain. Anticoagulants help to reduce this risk by inhibiting the clotting process. Therefore, choices A, C, and D are incorrect because anticoagulants do not primarily aim to reduce blood pressure, prevent arrhythmias, or reduce inflammation in patients with atrial fibrillation.

5. A client's laboratory findings indicate elevations in thyroxine and triiodothyronine hormones. The nurse suspects that the client may have hyperthyroidism. Which assessment finding is most often associated with hyperthyroidism?

• A. Periorbital edema.
• B. Atrophied thyroid gland.
• C. Increased pulse rate.
• D. Diarrhea stools.

Correct answer: C

Rationale: Increased pulse rate is commonly associated with hyperthyroidism due to the increased metabolic rate. Periorbital edema (Choice A) is more commonly associated with conditions like nephrotic syndrome or heart failure, not hyperthyroidism. Atrophied thyroid gland (Choice B) is not typically an assessment finding for hyperthyroidism as the gland is usually enlarged in this condition. Diarrhea stools (Choice D) can occur in hyperthyroidism, but it is not the most common assessment finding associated with the condition.
