1. Which lab value should be monitored for a patient on warfarin therapy?

A. Monitor INR
B. Monitor potassium levels
C. Monitor platelet count
D. Monitor sodium levels

Correct answer: A

Rationale: The correct answer is to monitor INR for a patient on warfarin therapy. INR monitoring is crucial as it helps assess the therapeutic effectiveness and safety of warfarin. INR stands for International Normalized Ratio, and it measures the blood's ability to clot. Monitoring potassium levels (Choice B) is not specific to warfarin therapy. Monitoring platelet count (Choice C) is important but not the primary lab value for assessing warfarin therapy. Monitoring sodium levels (Choice D) is not directly related to warfarin therapy.

2. A client has a new prescription for furosemide. Which of the following instructions should the nurse include during discharge teaching?

A. Avoid prolonged exposure to sunlight.
B. Take this medication with a meal.
C. Increase your intake of potassium-rich foods.
D. Limit your fluid intake to 1 liter per day.

Correct answer: C

Rationale: The correct instruction for a client taking furosemide is to increase their intake of potassium-rich foods. Furosemide is a loop diuretic that can lead to potassium loss, so increasing potassium-rich foods helps prevent hypokalemia. Choice A, avoiding prolonged exposure to sunlight, is not directly related to furosemide use. Choice B, taking the medication with a meal, is not a specific requirement for furosemide administration. Choice D, limiting fluid intake to 1 liter per day, is not the correct advice as furosemide is a diuretic that often requires increased fluid intake to prevent dehydration.

3. A nurse in a provider's office is reviewing the laboratory results of a group of clients. Which result is reportable?

A. Herpes simplex
B. Human papillomavirus
C. Candidiasis
D. Chlamydia

Correct answer: D

Rationale: Chlamydia is a reportable sexually transmitted infection. Reporting cases of Chlamydia to the health department is crucial for disease surveillance, contact tracing, and implementing public health interventions. Herpes simplex, human papillomavirus, and candidiasis are not typically reportable infections, as they do not pose the same public health risks as Chlamydia.

4. How should a healthcare professional assess a patient for dehydration?

A. Check for skin turgor
B. Monitor blood pressure
C. Check for dry mucous membranes
D. Monitor urine output

Correct answer: A

Rationale: Checking for skin turgor is a reliable method to assess dehydration in patients. Skin turgor refers to the skin's elasticity and hydration status. When a healthcare professional gently pinches the skin on the back of the patient's hand or forearm, dehydration is indicated by the skin not snapping back immediately. Monitoring blood pressure (choice B) is important but is more indicative of cardiovascular status rather than dehydration specifically. Checking for dry mucous membranes (choice C) can be a sign of dehydration, but skin turgor is a more direct assessment. Monitoring urine output (choice D) is also essential but may not provide immediate feedback on hydration status as skin turgor does.

5. What is the priority intervention for a patient with fluid overload?

A. Administer diuretics
B. Administer IV fluids
C. Provide oral fluids
D. Provide chest physiotherapy

Correct answer: A

Rationale: The correct answer is to administer diuretics. Diuretics help reduce excess fluid in cases of fluid overload, making it the priority intervention. Administering additional IV fluids (choice B) would exacerbate the problem by adding more fluid. Providing oral fluids (choice C) is not the priority as the excess fluid needs to be removed first. Chest physiotherapy (choice D) is not the primary intervention for fluid overload.
