Correct Answer: D

Rationale: When donning sterile gloves, it is essential to maintain sterility. The correct way to don sterile gloves includes grasping the outside of the cuff to put on the first glove and inserting the gloved fingers under the cuff outside the glove to put on the second glove. Adjustments should be made by sliding the fingers under the sterile cuff. It is crucial to remember that once the inside of the glove is touched during the donning process, it is no longer considered sterile.

Correct Answer: C

Rationale: Renal failure often necessitates fluid restriction to prevent fluid overload. In renal failure, the kidneys are unable to effectively filter and excrete excess fluids, leading to fluid accumulation in the body. Restricting fluid intake helps manage this condition by preventing further fluid buildup and complications such as edema and electrolyte imbalances.

Correct Answer: D

Rationale: Tachycardia is an increased heart rate, and it can be caused by various factors such as fever, exercise, and sympathetic nervous system stimulation, all of which tend to increase heart rate. However, parasympathetic nervous system stimulation typically slows the heart rate, making it the exception among the choices provided. Thus, parasympathetic nervous system stimulation is not a cause of tachycardia.

Correct Answer: A

Rationale: The symptoms of fatigue, muscle cramping, and muscle weakness in a patient after starting furosemide therapy are indicative of hypokalemia. Furosemide is a loop diuretic that can lead to potassium depletion, causing hypokalemia. Hypokalemia can manifest with muscle weakness, cramps, and fatigue due to alterations in neuromuscular function and decreased ATP production.

Correct Answer: C

Rationale: To determine the flow rate in drops per minute, multiply the ordered volume per hour by the drop factor (100 ml/hour x 15 gtt/ml = 1500 gtt/hour). Then, divide the result by 60 minutes to convert it to drops per minute (1500 gtt/hour · 60 minutes = 25 gtt/minute). Therefore, the correct answer is 25 gtt/minute.
