The nurse is teaching a patient who has been diagnosed with a gastric ulcer and has been prescribed an antacid. The patient demonstrates understanding when they state:
Taking antacids will allow me to eat as much spicy food as I want.
Taking antacids will prevent my stomach from digesting carbohydrates.
Taking antacids will prevent my stomach from making too much acid.
Taking antacids will help neutralize the acid that is already in my stomach.
The Correct Answer is D
Choice A reason: This is incorrect. Taking antacids does not protect the stomach from the irritation caused by spicy foods. Antacids only reduce the acidity of the stomach contents, but they do not heal the ulcer or prevent further damage.
Choice B reason: This is incorrect. Taking antacids does not affect the digestion of carbohydrates or any other nutrients. Antacids only act on stomach acid, not on the enzymes that break down food.
Choice C reason: This is incorrect. Taking antacids does not stop the stomach from producing acid. Antacids only react with the acid that is already present in the stomach, but they do not inhibit the secretion of acid by the stomach cells.
Choice D reason: This is correct. Taking antacids will help neutralize the acid that is already in the stomach, which can relieve the pain and discomfort caused by the ulcer. Antacids can also form a protective coating over the ulcer, which can help it heal faster.

Correct Answer is C
Explanation
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: This is correct. Hypertension is a contraindication for taking pseudoephedrine. Pseudoephedrine is a decongestant that shrinks the blood vessels in the nasal passages and relieves congestion. However, it can also increase the blood pressure and the heart rate, which can worsen hypertension and increase the risk of stroke, heart attack, or kidney damage. The nurse should advise the client to avoid pseudoephedrine and use other methods to relieve sinus congestion, such as saline nasal spray, steam inhalation, or humidifier.
Choice B reason: This is incorrect. Diverticulitis is not a contraindication for taking pseudoephedrine. Diverticulitis is a condition where small pouches in the colon become inflamed and infected. It can cause symptoms such as abdominal pain, fever, nausea, or constipation. Pseudoephedrine does not affect the colon or the inflammation directly, but it can cause dehydration, which can worsen constipation and diverticulitis. The nurse should advise the client to drink plenty of fluids and eat a highfiber diet to prevent constipation and diverticulitis.
Choice C reason: This is incorrect. Migraines are not a contraindication for taking pseudoephedrine. Migraines are severe headaches that are often accompanied by nausea, vomiting, or sensitivity to light and sound. They can be triggered by various factors, such as stress, hormones, or food. Pseudoephedrine does not cause migraines directly, but it can interact with some migraine medications, such as triptans, which are used to treat acute migraine attacks. The combination of pseudoephedrine and triptans can increase the blood pressure and the risk of serotonin syndrome, a serious condition that causes agitation, confusion, tremors, or seizures. The nurse should advise the client to check with their doctor before taking pseudoephedrine and triptans together.
Choice D reason: This is incorrect. Eczema is not a contraindication for taking pseudoephedrine. Eczema is a skin condition that causes dry, itchy, and inflamed skin. It can be caused by various factors, such as allergies, irritants, or genetics. Pseudoephedrine does not affect the skin or the inflammation directly, but it can cause dryness of the mucous membranes, such as the mouth, nose, or eyes. The nurse should advise the client to use a moisturizer, a lip balm, and artificial tears to prevent dryness and irritation of the skin and the mucous membranes.
