NEW QUESTION # 70
Which of the following signs is most frequently associated with meningitis?

A. positive Cullen's
B. positive Trousseau's
C. positive Babinski's
D. positive Kernig's

Answer: D

Explanation:

Meningitis
A positive Kernig's sign is a clinical test for meningitis that involves flexing the hip and knee of the patient and then extending the knee. If the patient feels pain or resistance in the lower back or hamstring, the test is positive. A positive Kernig's sign indicates irritation of the meninges, the membranes that cover the brain and spinal cord. A positive Trousseau's sign is a sign of hypocalcemia that involves carpal spasm after inflating a blood pressure cuff. A positive Cullen's sign is a sign of retroperitoneal bleeding that involves bruising around the umbilicus. A positive Babinski's sign is a sign of upper motor neuron lesion that involves fanning of the toes when the sole of the foot is stroked.

NEW QUESTION # 71
Which of the following ECG changes is expected in a patient with a potassium concentration of 3.0 mEq/L?

A. ST segment depression, flattened and inverted T wave, and a U wave
B. tall peaked T wave, prolonged PR interval, and prolonged QRS complex
C. shortened QT interval and complete atrioventricular block
D. inverted P wave, elevated T wave, and prolonged QT interval

Answer: A

Explanation:

Hypokalemia
A patient with a potassium concentration of 3.0 mEq/L has mild hypokalemia, which is a low level of potassium in the blood. Hypokalemia can cause various ECG changes that reflect the impairment of cardiac depolarization and repolarization. The most common ECG changes in mild hypokalemia are ST segment depression, flattened and inverted T wave, and a U wave, which is a positive deflection after the T wave.
These ECG changes can be seen in the examples from the web search results12. Other ECG changes that may occur in more severe hypokalemia are prolonged QT interval, frequent ectopic beats, and arrhythmias123. Tall peaked T wave, prolonged PR interval, and prolonged QRS complex are ECG changes associated with hyperkalemia, which is a high level of potassium in the blood12. Shortened QT interval and complete atrioventricular block are not typical ECG changes of hypokalemia, but may occur in other electrolyte disorders, such as hypercalcemia2. Inverted P wave, elevated T wave, and prolonged QT interval are not specific ECG changes of hypokalemia, but may occur in other cardiac conditions, such as ischemia, myocarditis, or pericarditis2.

NEW QUESTION # 72
A patient who recently lost their spouse is admitted following an emergent cardiac catheterization. The procedure report states chest pain and ST elevation, no significant coronary artery disease, left ventricular dysfunction with apical ballooning, and an EF of 35%. These findings are consistent for

A. takotsubo cardiomyopathy.
B. arrhythmogenic right ventricular cardiomyopathy.
C. non ischemic cardiomyopathy.
D. hypertrophic cardiomyopathy.

Answer: A

Explanation:
Takotsubo cardiomyopathy, also known as stress-induced cardiomyopathy or "broken heart syndrome," is characterized by transient left ventricular dysfunction often precipitated by significant emotional or physical stress. The key findings of chest pain and ST elevation without significant coronary artery disease, along with left ventricular dysfunction and apical ballooning observed on imaging, are classic for takotsubo cardiomyopathy. This condition is often reversible and is associated with a temporary reduction in the heart's pumping ability, indicated by the reduced ejection fraction (EF) of 35%. References: =

NEW QUESTION # 73
Which of the following is a cause of cardiogenic pulmonary edema?

A. RV chamber enlargement
B. pulmonary hypertension
C. LV noncompliance
D. elevated PAOP reading

Answer: C

Explanation:
Cardiogenic pulmonary edema is primarily caused by left ventricular (LV) noncompliance. When the left ventricle is unable to properly fill or eject blood, pressure increases in the left atrium and pulmonary veins, leading to fluid leakage into the pulmonary interstitium and alveoli, causing pulmonary edema. Elevated PAOP readings, RV chamber enlargement, and pulmonary hypertension are not primary causes of cardiogenic pulmonary edema but can be related to other cardiac conditions.

NEW QUESTION # 74
After observing an increase in the occurrence of oral pressure injuries in intubated patients on the unit, the nurse should

A. discuss concerns at the next unit based practice meeting.
B. report the issue to the respiratory therapy manager.
C. continue to provide oral care to intubated patients.
D. recommend removal endotracheal tube holders from the unit.

Answer: A

Explanation:
When noticing an increase in the occurrence of oral pressure injuries in intubated patients, it is essential to address this issue in a structured and collaborative manner. Discussing concerns at the next unit-based practice meeting allows for a multidisciplinary approach to identify possible causes, review current practices, and implement evidence-based interventions to prevent further occurrences. This approach fosters a culture of continuous improvement and ensures that the issue is addressed comprehensively. References: =
