Question 1 of 5
A female patient with atrial fibrillation has the following lab results: Hemoglobin of 11 g/dl, a platelet count of 150,000, an INR of 2.5, and potassium of 2.7 mEq/L. Which result is critical and should be reported to the physician immediately?
Correct Answer: D
Rationale: The critical lab result that should be reported to the physician immediately in this case is the potassium level of 2.7 mEq/L. A potassium imbalance, especially in a patient with a history of dysrhythmia like atrial fibrillation, can be life-threatening and lead to cardiac distress. Low potassium levels (hypokalemia) can predispose the patient to dangerous arrhythmias, including worsening atrial fibrillation. Hemoglobin of 11 g/dl, platelet count of 150,000, and an INR of 2.5 are within acceptable ranges and not as immediately concerning as a low potassium level in this clinical context.
Question 2 of 5
Which of the following types of dressing changes works as a form of wound debridement?
Correct Answer: D
Rationale: The correct answer is 'Wet to dry dressing.' Wet to dry dressing is a method of wound debridement that involves applying sterile soaked gauze to the wound, allowing it to dry and stick to the wound. When the dressing is removed, it pulls away drainage and debris, aiding in wound debridement.
Choice A, 'Dry dressing,' does not actively assist in debridement as it does not collect or remove debris from the wound.
Choice B, 'Transparent dressing,' is primarily used for maintaining a moist environment and wound observation, not for debridement.
Choice C, 'Composite dressing,' combines multiple layers for different wound care purposes but is not specifically designed for debridement like wet to dry dressing.
Question 3 of 5
While receiving normal saline infusions to treat a GI bleed, the nurse notes that the patient's lower legs have become edematous and auscultates crackles in the lungs. What should the nurse do first?
Correct Answer: A
Rationale: The correct answer is to stop the saline infusion immediately. The patient is showing signs of fluid volume overload due to rapid fluid replacement, indicated by lower leg edema and lung crackles. Continuing the infusion could worsen the overload and potentially lead to complications. Notifying the physician is important but should come after stopping the infusion to address the immediate issue. Elevating the patient's legs may help with edema but is not the priority in this situation. Continuing the infusion when the patient is already showing signs of fluid overload is contraindicated and can be harmful.
Question 4 of 5
Which finding would necessitate an immediate change in the therapeutic plan for a patient with grade 2 hepatic encephalopathy?
Correct Answer: B
Rationale: A positive urine pregnancy test would require an immediate change in the therapeutic plan for a patient with grade 2 hepatic encephalopathy due to the teratogenic effects of ribavirin. Ribavirin needs to be discontinued immediately to prevent harm to the fetus. The other options, weight loss, hemoglobin level, and complaints of nausea and anorexia, are common adverse effects of the prescribed regimen and may necessitate interventions such as patient education or supportive care, but they would not mandate an immediate cessation of therapy as in the case of a positive pregnancy test.
Question 5 of 5
Which action will be included in the care for a patient who has recently been diagnosed with asymptomatic nonalcoholic fatty liver disease (NAFLD)?
Correct Answer: D
Rationale: The correct action for a patient diagnosed with asymptomatic nonalcoholic fatty liver disease (NAFL
D) would be to review the patient's current medication list. This is important because certain medications can increase the risk for NAFLD, and they should be identified and possibly eliminated. Teaching about symptoms of variceal bleeding is not necessary as variceal bleeding is not a concern in a patient with asymptomatic NAFLD. Drawing blood for hepatitis serology testing is not indicated as NAFLD is not associated with hepatitis. Discussing the need to increase caloric intake is also not appropriate since weight loss is usually recommended in the management of NAFLD.
