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 A
Explanation
Choice A reason: Relief of heartburn is the correct outcome that indicates that famotidine is therapeutic. Famotidine is a medication that belongs to the class of H2 receptor antagonists, which work by blocking the action of histamine on the H2 receptors of the stomach cells, thereby reducing the production of gastric acid. Famotidine is used to treat and prevent conditions such as gastroesophageal reflux disease (GERD), peptic ulcer disease, and Zollinger Ellison syndrome, which are characterized by excessive acid secretion and irritation of the esophagus and stomach. Famotidine can relieve the symptoms of heartburn, which is a burning sensation in the chest or throat caused by the reflux of stomach acid into the esophagus.
Choice B reason: Cessation of diarrhea is not an outcome that indicates that famotidine is therapeutic. Famotidine is a medication that belongs to the class of H2 receptor antagonists, which work by blocking the action of histamine on the H2 receptors of the stomach cells, thereby reducing the production of gastric acid. Famotidine does not affect the motility or secretion of the intestines, and it is not used to treat diarrhea, which is a condition of frequent and loose bowel movements. Diarrhea can have various causes, such as infections, medications, food intolerance, or inflammatory bowel disease, and it requires different treatments depending on the underlying cause. Famotidine is not effective for treating diarrhea, and it may even worsen it by reducing the acidity of the stomach and increasing the risk of bacterial overgrowth.
Choice C reason: Passage of flatus is not an outcome that indicates that famotidine is therapeutic. Famotidine is a medication that belongs to the class of H2 receptor antagonists, which work by blocking the action of histamine on the H2 receptors of the stomach cells, thereby reducing the production of gastric acid. Famotidine does not affect the digestion or fermentation of food in the gastrointestinal tract, and it is not used to treat flatulence, which is the accumulation and expulsion of gas from the stomach or intestines. Flatulence can have various causes, such as swallowing air, eating certain foods, or having a bacterial imbalance in the gut, and it requires different treatments depending on the underlying cause. Famotidine is not effective for treating flatulence, and it may even increase it by reducing the acidity of the stomach and altering the gut flora.
Choice D reason: Absence of constipation is not an outcome that indicates that famotidine is therapeutic. Famotidine is a medication that belongs to the class of H2 receptor antagonists, which work by blocking the action of histamine on the H2 receptors of the stomach cells, thereby reducing the production of gastric acid. Famotidine does not affect the motility or secretion of the intestines, and it is not used to treat constipation, which is a condition of infrequent or difficult bowel movements. Constipation can have various causes, such as dehydration, lack of fiber, medications, or bowel obstruction, and it requires different treatments depending on the underlying cause. Famotidine is not effective for treating constipation, and it may even cause it by reducing the acidity of the stomach and slowing down the digestion.
Correct Answer is B
Explanation
Choice A reason: This is incorrect. Lisinopril is an angiotensin converting enzyme (ACE) inhibitor that lowers blood pressure and reduces the workload of the heart. It does not have a diuretic effect, meaning it does not increase urination.
Choice B reason: This is correct. Lisinopril can cause orthostatic hypotension, which is a sudden drop in blood pressure when changing positions. This can lead to dizziness, fainting, or falls. To prevent this, the nurse should instruct the client to rise slowly from sitting or lying positions and to avoid sudden movements.
Choice C reason: This is incorrect. Lisinopril can be taken with or without food. Taking it on an empty stomach does not improve its effectiveness or reduce its side effects.
Choice D reason: This is incorrect. Lisinopril does not cause weight gain due to fluid retention. In fact, it can help reduce edema, which is swelling caused by excess fluid in the body.
