Question 1 of 5
A client receiving azathioprine (Imuran) complains of hair loss. The nurse tells the client that?
Correct Answer: C
Rationale: Hair loss is a known but temporary side effect of azathioprine, an immunosuppressant used to treat autoimmune conditions. It occurs due to the drug's impact on rapidly dividing cells, including hair follicles. While distressing, this side effect is usually reversible once the medication is discontinued or the body adjusts to it. Hair loss is not typically a sign of toxicity, and reassuring the client about its temporary nature can help alleviate anxiety.
Question 2 of 5
Deficiencies in cyanocobalamin (B12) can result in
Correct Answer: B
Rationale: Cyanocobalamin, or vitamin B12, is essential for red blood cell production and neurological function, and its deficiency directly leads to pernicious anemia, a condition characterized by large, immature red blood cells due to impaired DNA synthesis. This occurs because B12 is crucial for folate metabolism and erythropoiesis, and without it, anemia develops, often accompanied by neurological symptoms like numbness or tingling. Pellagra, however, results from niacin (vitamin B3) deficiency, manifesting as dermatitis, diarrhea, and dementia-unrelated to B12's role. Rickets stems from vitamin D deficiency, causing bone deformities due to poor calcium absorption, not a B12 issue. Scurvy arises from vitamin C deficiency, leading to collagen breakdown and symptoms like bleeding gums, distinct from B12's hematological effects. Pernicious anemia stands out as the correct outcome because B12 deficiency disrupts bone marrow function, and it often requires pharmacotherapy, such as B12 injections, especially if absorption is impaired (e.g., due to lack of intrinsic factor). This specificity eliminates other conditions, highlighting B12's unique role in blood and nerve health.
Question 3 of 5
The application of drugs for the purpose of treating diseases and treatment of suffering is known as
Correct Answer: B
Rationale: Pharmacotherapeutics applies drugs to treat diseases and alleviate suffering, combining pharmacology and therapeutic intent, a precise term. Biologics are drug types, not application. Alternative therapies use non-drug methods. Therapeutics is broader, but pharmacotherapeutics specifies drug use, aligning with the definition and clinical practice.
Question 4 of 5
The nurse plans to administer medication to the preschool child. Which approach indicates the nurse has an understanding of growth and development?
Correct Answer: D
Rationale: Preschoolers (3-5) respond to simple explanations and swift action-e.g., 'This helps you feel better,' then give-matching their short attention and trust needs. Parents often calm, not hinder, cooperation. Play aids understanding, not just verbal. Restraint may be needed if uncooperative-age doesn't rule it out. Brief rationale and quick delivery suit developmental stage, minimizing distress.
Question 5 of 5
The 8-year-old patient is receiving methylphenidate (Ritalin). The patient's mother tells the nurse that he won't eat while on his medication. What is the best response by the nurse?
Correct Answer: B
Rationale: Methylphenidate curbs appetite-giving it post-meals and adding snacks offsets weight loss, per practical management. Depression isn't indicated-appetite loss is a known effect. Appetite stimulants aren't standard. Nutritionists help long-term, not acutely. Post-meal dosing balances efficacy and nutrition, per care.
