A nurse is assessing a client who is taking an osmotic laxative.
Which of the following findings should the nurse identify as an indication of fluid volume deficit?
Oliguria.
Nausea.
Headaches.
Weight gain.
The Correct Answer is A
Osmotic laxatives work by drawing water into the colon to soften the stool and stimulate bowel movements. However, excessive use of osmotic laxatives can cause fluid volume deficit, which is a state of reduced intravascular volume.
One of the signs of fluid volume deficit is oliguria, which means low urine output.
Choice B. Nausea is wrong because nausea is a common side effect of osmotic laxatives, not an indication of fluid volume deficit.
Choice C. Headaches is wrong because headaches are more likely to be caused by dehydration, which is a state of reduced total body water, mostly affecting the intracellular fluid compartment.
Dehydration can result from osmotic laxatives, but it is not the same as fluid volume deficit.
Choice D. Weight gain is wrong because weight gain is not a sign of fluid volume deficit.

Correct Answer is D
Explanation
This site is preferred for peripheral IV catheter placement because it is comfortable, has good blood flow, and has a lower risk of complications than the dominant arm or the antecubital fossa.
Choice A is wrong because the dominant antecubital basilic vein is more prone to dislodgement, thrombosis, and thrombophlebitis due to frequent movement of the elbow joint.
Choice B is wrong because the nondominant dorsal venous arch is a distal site that may have poor blood flow and higher resistance to infusion. It should be avoided unless there are no other options.
Choice C is wrong because the dominant distal dorsal vein is also a distal site that may have poor blood flow and higher resistance to infusion. It should be avoided unless there are no other options.
Correct Answer is A
Explanation
According to various guidelines12345, the recommended rate of intravenous potassium replacement is 10-20 mEq/h with continuous ECG monitoring. The maximum rate is 40 mEq/h in emergency situations. The prescription given by the provider exceeds this limit and could cause cardiac arrhythmias or hyperkalemia.
Choice B is wrong because potassium chloride is a common and appropriate formulation of potassium for intravenous administration.
Choice C is wrong because potassium chloride should not be diluted in dextrose 5% in water, as this could cause hyperglycemia or osmotic diuresis.
Choice D is wrong because potassium should never be given by IV bolus, as this could cause cardiac arrest or tissue necrosis.
