Mod 10- Drugs for Anemias Flashcards
Which of the following instructions or patient education points is best associated with iron (ferrous sulfate)?
Keep out of Reach from Children
Explanation:
Since excessive amounts of iron is toxic, accidental or intentional overdose leads to poisoning. Iron preparations should be stored in childproof containers and kept out of reach of children.
Which of the following instructions or patient education points associated with iron (ferrous sulfate) improves absorption but may worsen GI side effects
Take Between Meals
Explanation:
Iron is best absorbed on an empty stomach. Certain dietary components may chelate iron and prevent it from being absorbed. Patients should thus be instructed not to take this medication with food. However, this will increase the incidence of GI upset. If patients cannot tolerate the increased GI side effects, they can be instructed to take iron with meals to increase medication adherence
Which of the following instructions or patient education points is best associated with iron (ferrous sulfate)?
Caution with GI Disorders
Explanation:
Since iron preparations cause GI effects, this medication may worsen symptoms associated with peptic ulcers, ulcerative colitis, and regional enteritis. Patients with these conditions should use this medication cautiously and avoid oral iron preparations.
Which of the following considerations is most important when administering iron (ferrous sulfate)?
Liquid can Stain Teeth
Explanation:
Liquid preparations of ferrous sulfate may stain teeth. Instruct the patient to dilute liquid iron preparations with juice or water, administer through a straw, and rinse the mouth after taking the medication.
Which of the following side effects is most likely associated with iron (ferrous sulfate) administration?
GI Distress
Explanation:
The body’s level of iron is regulated by intestinal absorption. Ferrous sulfate may cause GI distress such as heartburn (pyrosis), constipation, diarrhea, and bloating. These symptoms are dose-dependent and typically decrease with continued drug therapy. Patients experiencing constipation may benefit from a stool softener or laxative.
What mechanism of action or pharmacological action is best associated with iron (ferrous sulfate)?
Ferrous Salts
Explanation:
Iron is an essential component of hemoglobin, myoglobin, and certain enzymes. The bone marrow utilizes iron to make hemoglobin, the liver stores iron as ferritin, and the muscles incorporate iron to produce myoglobin. The body requires iron to transport oxygen throughout the body.
Which of the following instructions or patient education points is best associated with iron (ferrous sulfate)?
Avoid Antacids
Explanation:
Antacids decrease the body’s ability to absorb iron and should not be taken with ferrous sulfate.
Which of the following diseases or disorders is iron (ferrous sulfate) most likely indicated for?
Anemia
Explanation:
A deficiency in iron absorption leads to a decreased production of hemoglobin. Since hemoglobin is responsible for carrying oxygen throughout the body, the patient develops anemia and presents with fatigue and pallor. This drug also prevents iron deficiency associated with pregnancy or chronic blood loss. With iron deficiency anemia, the RBCs are microcytic and hypochromic.
Which of the following side effects is most likely associated with iron (ferrous sulfate) administration AND tends to worry patients upon incidence though harmless?
Dark Stools
Explanation:
Although ferrous sulfate may cause dark green or black-colored stools, inform the patient that this is a harmless side effect and not indicative of bleeding.
Which of the following side effects is most likely associated with iron (ferrous sulfate) administration AND diminishes with continued use?
Nausea and Vomiting
Explanation:
Administering ferrous sulfate increases the body’s amount of iron and subsequently affects the GI system’s ability to absorb the mineral. Symptoms of GI distress caused by iron preparations include nausea and vomiting. Inform the patient that continued therapy often leads to decreased symptoms.
Disorder involving too few red blood cells (RBCs) or ineffective RBCs that can alter the blood’s ability to carry oxygen
anemia
RBC that has lost its nucleus and entered circulation just recently, not yet fully matured
reticulocyte
Process of RBC production and life
erythropoiesis
Selective serotonin receptor blocker that causes a vascular constriction of cranial vessels; used to treat acute migraine attacks
triptan
Drug that causes a vascular constriction in the brain and the periphery; relieves or prevents migraine headaches but is associated with many adverse effects
ergot derivative
Drugs originally derived from opium that react with specific opioid receptors throughout the body
opioids
