1. What is the primary purpose of administering insulin to a patient with diabetes?

• A. Regulate blood glucose levels
• B. Increase metabolism
• C. Prevent complications
• D. Promote insulin sensitivity

Correct answer: A

Rationale: The correct answer is A: 'Regulate blood glucose levels.' Administering insulin to a patient with diabetes helps regulate blood glucose levels by facilitating the uptake of glucose into cells, thereby lowering high blood sugar levels. This process aims to prevent hyperglycemia and its associated complications. Choice B, 'Increase metabolism,' is incorrect as the primary role of insulin is not to increase metabolism directly. Choice C, 'Prevent complications,' is partially correct as regulating blood glucose through insulin administration does help prevent complications associated with uncontrolled diabetes, but it is not the primary purpose. Choice D, 'Promote insulin sensitivity,' is incorrect as insulin itself is administered to compensate for the lack of endogenous insulin in diabetic patients, rather than to promote sensitivity to it.

2. Which diagnostic test is used to confirm tuberculosis (TB) infection?

• A. Chest X-ray
• B. Sputum culture
• C. Skin test (Mantoux)
• D. MRI

Correct answer: C

Rationale: The Mantoux skin test, also known as the Tuberculin Skin Test (TST), is used to confirm tuberculosis (TB) infection. This test involves injecting a small amount of tuberculin protein derivative under the top layer of the skin and then evaluating the immune system's response to the protein. A positive reaction indicates exposure to the TB bacteria. Chest X-rays are used to detect abnormalities in the lungs caused by TB but are not confirmatory. Sputum culture is used to identify the presence of TB bacteria in the sputum. MRIs are not typically used as a primary diagnostic tool for TB.

3. Which electrolyte imbalance should be closely monitored in patients on diuretics?

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

Correct answer: A

Rationale: The correct answer is A: Hypokalemia. Patients on diuretics are at risk of developing hypokalemia due to increased potassium excretion by the kidneys. Hypokalemia can lead to serious consequences such as cardiac arrhythmias. Hyponatremia (choice B) is an imbalance of sodium levels and is not typically associated with diuretic use. Hyperkalemia (choice C) is the opposite condition where potassium levels are elevated and is less common in patients on diuretics. Hypercalcemia (choice D) is an excess of calcium in the blood and is not directly related to diuretic use. Therefore, monitoring for hypokalemia is crucial in patients taking diuretics.

4. A healthcare professional is preparing to administer a blood transfusion to a client. Which of the following actions should the healthcare professional take first?

• A. Obtain the client's vital signs.
• B. Ensure the client's IV access is patent.
• C. Prime the IV tubing with 0.9% sodium chloride.
• D. Verify the client's identity.

Correct answer: D

Rationale: Verifying the client's identity is the first crucial action the healthcare professional should take before administering a blood transfusion. This step ensures that the right blood is given to the right client, helping prevent errors. Obtaining vital signs, ensuring IV access, and priming IV tubing are important steps in the process but verifying the client's identity takes precedence for patient safety and accurate care delivery.

5. Which lab value should be monitored in a patient on digoxin?

• A. Monitor potassium levels
• B. Monitor calcium levels
• C. Monitor digoxin levels
• D. Monitor sodium levels

Correct answer: C

Rationale: The correct answer is to monitor digoxin levels in a patient on digoxin. Digoxin is a medication commonly used to treat heart conditions, and monitoring its levels in the blood is crucial to ensure that the patient is within the therapeutic range and to prevent toxicity. Monitoring potassium levels (Choice A) is important due to the potential of digoxin-induced hypokalemia, but the primary focus should be on monitoring digoxin levels. Monitoring calcium levels (Choice B) and sodium levels (Choice D) are not directly related to digoxin therapy and are not the primary lab values of concern when administering digoxin.
