Question 1 of 5
The nurse is assessing a client with left-sided heart failure. Which laboratory value is most concerning?
Correct Answer: C
Rationale: A serum potassium level of 5.5 mEq/L is most concerning in a client with left-sided heart failure as it indicates hyperkalemia, requiring immediate intervention. Hyperkalemia can lead to life-threatening cardiac arrhythmias, which can exacerbate heart failure. Serum creatinine of 1.5 mg/dL is slightly elevated but not as immediately concerning as hyperkalemia. Serum sodium of 136 mEq/L is within the normal range. Hemoglobin of 12 g/dL is also within the normal range and not directly related to the client's left-sided heart failure.
Question 2 of 5
A male client with hypertension, who received new antihypertensive prescriptions at his last visit, returns to the clinic two weeks later to evaluate his blood pressure (BP). His BP is 158/106, and he admits that he has not been taking the prescribed medication because the drugs make him 'feel bad'. In explaining the need for hypertension control, the nurse should stress that an elevated BP places the client at risk for which pathophysiological condition?
Correct Answer: C
Rationale: The correct answer is C, 'Stroke secondary to hemorrhage.' Uncontrolled hypertension can lead to the weakening of blood vessels in the brain, increasing the risk of a stroke due to hemorrhage. This can result in serious neurological deficits or even death. Choices A, B, and D are incorrect because while hypertension can have various complications including vision changes, kidney damage, and heart problems, the most immediate and severe risk associated with uncontrolled hypertension is a stroke from cerebral hemorrhage.
Question 3 of 5
During shift report, the central electrocardiogram (EKG) monitoring system alarms. Which client alarm should the nurse investigate first?
Correct Answer: A
Rationale: The correct answer is A: Respiratory apnea of 30 seconds. Respiratory apnea indicates a cessation of breathing, which is a life-threatening emergency requiring immediate intervention. Priority should be given to assessing and managing airway, breathing, and circulation. Option B, oxygen saturation rate of 88%, can indicate hypoxemia, but addressing the lack of breathing takes precedence. Option C, eight premature ventricular beats every minute, and option D, a disconnected monitor signal, are important but do not pose an immediate threat to the client's life compared to respiratory apnea.
Question 4 of 5
A client with a history of atrial fibrillation is prescribed warfarin (Coumadin). Which laboratory value is most concerning?
Correct Answer: A
Rationale: An INR of 3.0 is most concerning in a client prescribed warfarin (Coumadin) as it indicates a high risk of bleeding, requiring immediate intervention. A high INR value suggests that the blood is taking longer to clot, putting the patient at an increased risk of hemorrhage. Prothrombin time (PT) measures how long it takes for blood to clot, but the specific value of 15 seconds is within the normal range. Hemoglobin of 10 g/dl indicates mild anemia and does not directly relate to the risk of bleeding associated with warfarin therapy. White blood cell count assesses immune function and infection risk, but it is not directly related to the anticoagulant effects of warfarin.
Question 5 of 5
A client with a history of atrial fibrillation is prescribed warfarin (Coumadin). Which clinical finding is most concerning?
Correct Answer: A
Rationale: The correct answer is A: Headache. In a client with atrial fibrillation taking warfarin (Coumadin), a headache can be indicative of bleeding, which is a serious complication requiring immediate assessment and intervention. Monitoring for signs of bleeding is crucial when on anticoagulant therapy. Choices B, C, and D are not the most concerning. A prothrombin time of 15 seconds is within the therapeutic range for a client on warfarin, elevated liver enzymes may indicate liver dysfunction but are not directly related to the medication's side effects, and peripheral edema is not typically associated with warfarin use or atrial fibrillation in this context.
