What is the fastest route for medication administration?
SQ (subcutaneous)
PO (by mouth)
IV (intravenous)
IM (intramuscular)
The Correct Answer is C
Choice A reason: This is incorrect. SQ (subcutaneous) administration involves injecting a drug into the fatty tissue under the skin. This route is slower than IV or IM administration, as the drug has to diffuse through the tissue before reaching the bloodstream.
Choice B reason: This is incorrect. PO (by mouth) administration involves swallowing a drug and absorbing it through the digestive system. This route is the slowest of all, as the drug has to pass through the stomach and the liver before reaching the bloodstream. The drug may also be affected by the first pass effect, which reduces its bioavailability.
Choice C reason: This is correct. IV (intravenous) administration involves injecting a drug directly into a vein. This route is the fastest of all, as the drug enters the bloodstream immediately and reaches the target site quickly. The drug also has 100% bioavailability, meaning none of it is lost or degraded.
Choice D reason: This is incorrect. IM (intramuscular) administration involves injecting a drug into a muscle. This route is faster than SQ or PO administration, as the drug can be absorbed by the capillaries in the muscle. However, it is still slower than IV administration, as the drug has to cross the muscle membrane before reaching the bloodstream.

Correct Answer is D
Explanation
Choice A reason: Administering half of the scheduled dose of Colace is not the correct action for the nurse who is caring for a patient who had two loose stools during the night shift. Colace is the brand name of docusate, which is a stool softener that works by increasing the amount of water and fat in the stool, making it easier to pass. Colace is used to treat and prevent constipation, which is a condition of infrequent or hard bowel movements. Colace is not indicated for diarrhea, which is a condition of frequent and loose bowel movements. Administering half of the scheduled dose of Colace may not be enough to prevent constipation, and it may also worsen diarrhea by adding more water and fat to the stool.
Choice B reason: Administering the scheduled dose of Colace is not the correct action for the nurse who is caring for a patient who had two loose stools during the night shift. Colace is the brand name of docusate, which is a stool softener that works by increasing the amount of water and fat in the stool, making it easier to pass. Colace is used to treat and prevent constipation, which is a condition of infrequent or hard bowel movements. Colace is not indicated for diarrhea, which is a condition of frequent and loose bowel movements. Administering the scheduled dose of Colace may not be necessary to prevent constipation, and it may also worsen diarrhea by adding more water and fat to the stool.
Choice C reason: Inserting a rectal tube to prevent excoriation is not the correct action for the nurse who is caring for a patient who had two loose stools during the night shift. A rectal tube is a device that is inserted into the rectum and connected to a drainage bag, which collects the stool and prevents leakage and skin irritation. A rectal tube is used for patients who have fecal incontinence, which is the inability to control bowel movements. A rectal tube is not indicated for patients who have diarrhea, which is a condition of frequent and loose bowel movements. Inserting a rectal tube may not be effective to prevent excoriation, and it may also cause complications such as infection, bleeding, or perforation.
Choice D reason: Holding the scheduled dose of Colace and notifying the ordering physician is the correct action for the nurse who is caring for a patient who had two loose stools during the night shift. Colace is the brand name of docusate, which is a stool softener that works by increasing the amount of water and fat in the stool, making it easier to pass. Colace is used to treat and prevent constipation, which is a condition of infrequent or hard bowel movements. Colace is not indicated for diarrhea, which is a condition of frequent and loose bowel movements. Holding the scheduled dose of Colace may be appropriate to avoid further diarrhea, and notifying the ordering physician may be necessary to determine the cause and the treatment of diarrhea
Correct Answer is C
Explanation
Choice A reason: Serum sodium level of 140 mEq/L is within the normal range of 135145 mEq/L. It does not indicate any adverse effect of the potassium sparing diuretic, which does not affect sodium excretion significantly. The nurse does not need to notify the health care provider about this finding.
Choice B reason: Blood pressure of 130/80 mmHg is slightly above the normal range of 120/80 mmHg, but it is not a cause for concern. The potassium sparing diuretic can lower the blood pressure by reducing the fluid volume and preventing sodium retention. The nurse should monitor the blood pressure regularly but does not need to notify the health care provider about this finding.
Choice C reason: Serum potassium level of 5.5 mEq/L is above the normal range of 3.55.0 mEq/L. It indicates hyperkalemia, which is a serious and potentially life-threatening complication of the potassium sparing diuretic. The potassium sparing diuretic can increase the potassium level by inhibiting its secretion in the distal tubule of the kidney. The nurse should notify the health care provider immediately and prepare to administer interventions such as calcium gluconate, insulin, or sodium bicarbonate to lower the potassium level and prevent cardiac arrhythmias.
Choice D reason: Serum potassium level of 3.5 mEq/L is at the lower end of the normal range of 3.55.0 mEq/L. It does not indicate any adverse effect of the potassium sparing diuretic, which does not cause potassium loss. The nurse does not need to notify the health care provider about this finding.
