Question 1 of 5
At what point does atropine hit its peak for IM injections?
Correct Answer: A
Rationale: Atropine given via intramuscular (IM) injection typically reaches its peak effects within 15 to 50 minutes after administration. The onset of action is relatively rapid, with faster absorption and distribution compared to oral administration. The effects of atropine can be seen within minutes, reaching peak concentration within the specified time frame. This rapid onset is important clinically when atropine is used to treat conditions such as bradycardia or nerve agent poisoning where a quick response is needed.
Question 2 of 5
Which of the following does NOT describe Reye's syndrome :
Correct Answer: D
Rationale: Reye's syndrome is a rare but serious disorder that primarily affects children and teenagers. It is characterized by an acute encephalopathic illness along with fatty degeneration of the liver and other viscera. Reye's syndrome typically arises after a viral infection, such as influenza or chickenpox, rather than being enhanced by sodium and water retention. This condition is not caused by excessive sodium and water retention but rather by a possible link to the use of aspirin during viral infections in children.
Question 3 of 5
A patient who has been taking a benzodiazepine as a sleep aid for several months wishes to stop taking the medication. The nurse will suggest that the patient taper the dose gradually to avoid which effect?
Correct Answer: D
Rationale: Benzodiazepines, such as medications used for sleep aid, are known for their potential to cause physical dependence. If a patient abruptly stops taking benzodiazepines after using them regularly for an extended period, they are at risk of experiencing withdrawal symptoms. These withdrawal symptoms can be severe and may include rebound insomnia, anxiety, agitation, tremors, sweating, and even seizures in some cases. To prevent or minimize the likelihood of withdrawal symptoms, it is important for patients to gradually taper off the medication under the guidance of a healthcare provider. This gradual tapering helps the body adjust slowly to decreasing doses of the medication, reducing the risk of withdrawal effects.
Question 4 of 5
A patient receiving a targeted therapy asks the nurse why St. John's wort must be avoided. Which response by the nurse is most appropriate?
Correct Answer: B
Rationale: St. John's wort induces the activity of cytochrome P450 enzymes, which metabolize many targeted therapies. This can lead to decreased blood levels of the targeted therapy, reducing its effectiveness. Patients should be advised to avoid St. John's wort to ensure optimal therapeutic outcomes. The other options are incorrect because St. John's wort does not increase blood levels of targeted therapies, cause overdose, or bind with drugs in the intestinal tract.
Question 5 of 5
The nurse is doing health teaching with a patient with psoriasis. Which nursing implication is a priority for a patient on infliximab to treat psoriasis?
Correct Answer: D
Rationale: Infliximab, a biologic agent used to treat psoriasis, can suppress the immune system and increase the risk of infections and blood disorders. Monitoring the complete blood count (D) is a priority to detect neutropenia, anemia, or thrombocytopenia. Monitoring weight (A), electrolytes (B), or urine output (C) is not typically associated with infliximab therapy.
