Question 1 of 5
Which of the following is described as the fastest route of drug administration?
Correct Answer: A
Rationale: Intravenous (I.V.) administration is described as the fastest route of drug administration because the medication is directly delivered into the bloodstream. This allows for immediate systemic circulation and rapid onset of action, making it the most efficient route for drugs to reach their target organs or tissues. In contrast, other routes such as intramuscular (I.M), oral, rectal, and intradermal have slower absorption rates and may involve additional barriers before reaching the bloodstream, causing a delay in onset of action compared to intravenous administration.

Question 3 of 5
The nurse administers IV morphine to a postoperative client. Which parameter should the nurse assess first after administration?
Correct Answer: B
Rationale: Morphine, an opioid, relieves pain but depresses respiration via mu-receptor agonism. Assessing respiratory rate first detects early depression (e.g., <12 bpm), a life-threatening risk requiring immediate action (e.g., naloxone). Pain level gauges efficacy but follows safety. Blood pressure and pulse may drop, but respiratory compromise is morphine's primary danger post-op, where patients are vulnerable. Prioritizing breathing aligns with ABCs (airway, breathing, circulation) and morphine's pharmacology, ensuring oxygenation before comfort. This sequence prevents overdose escalation, making B the first parameter to assess after administration.
Question 4 of 5
The nurse has completed medication education with the patient who is receiving risperidone (Risperdal). The nurse evaluates that the education has been effective when the patient makes which statement?
Correct Answer: B
Rationale: Risperidone risks agranulocytosis, requiring blood monitoring . This statement shows understanding of a critical safety step, indicating effective education. Nightmares , weight loss , and metallic taste aren't key concerns. B ensures safety, making it the best indicator.
Question 5 of 5
The nurse is caring for a patient who is taking warfarin. The nurse notes the presence of gross hematuria and large areas of bruising on the patient's body. The nurse notifies the health care prescriber and anticipates what medication will be ordered?
Correct Answer: C
Rationale: Gross hematuria and bruising are signs of excessive anticoagulation, likely due to warfarin. Phytonadione (Vitamin K) is the antidote for warfarin toxicity and will be ordered to reverse its effects. Heparin sulfate (A) and protamine sulfate (B) are used for heparin reversal, and potassium supplements (D) are unrelated to warfarin toxicity.
