Which of the following is a symptom consistent with the Ebola virus disease?

Correct Answer: D

Rationale: All listed symptoms (fever, malaise, vomiting, and diarrhea) are characteristic of Ebola virus disease, making 'All of the above' the correct choice.

Correct Answer: A

Rationale: Left-sided heart failure is characterized by pulmonary congestion and edema. Right-sided heart failure is characterized by congestion in the systemic venous system that increases systemic vascular resistance. Jugular vein distention is a classic sign of right-sided heart failure. Peripheral edema is seen in right-sided failure.

Correct Answer: B

Rationale: Heart failure is the fastest growing cardiac disorder at this time. The incidence and hospitalization rates associated with heart failure are reflective of the aging population in the United States. The incidence of heart failure is 10 per 1000 population in people over 65. Heart failure affects about 5.7 million Americans. More than 550,000 new cases of heart failure are diagnosed in the United States each year.

Correct Answer: C

Rationale: Tall peaked T-waves indicate hyperkalemia (K+ 8.0, C), a side effect of Spironolactone, a potassium-sparing diuretic.

Correct Answer: B

Rationale: Hypokalemia is a frequent adverse effect of the loop diuretics and can cause life-threatening dysrhythmias. The health care provider should be notified of the potassium level immediately and administration of potassium supplements initiated. The elevated blood glucose and BP also need collaborative intervention but will not require action as urgently as the hypokalemia. An orthostatic drop of 12 mm Hg will require intervention only if the patient is symptomatic.
