A nurse is reinforcing teaching with a group of nurses about medication administration. Which of the following routes of administration provides the most rapid onset for the client?
intravenous
Topical patch
Sublingual
Intramuscular
The Correct Answer is A
A. Intravenous: IV administration delivers medication directly into the bloodstream, allowing for the fastest onset of action (within seconds to minutes).
B. Topical patch: Slow absorption, designed for long-term, sustained release.
C. Sublingual: Faster than oral, but slower than IV (absorbed through mucous membranes).
D. Intramuscular: Faster than oral, but slower than IV, as the drug must diffuse into the bloodstream from muscle tissue.

Correct Answer is D
Explanation
A. Glucose of 6.7 mg/dL: Critically low; however, this is an unrealistic value because normal fasting glucose is 70-100 mg/dL. This might be a typo—if it were 6.7 mmol/L, it would be within the normal range.
B. WBC of 7000/mm³: Normal range (4,000-11,000/mm³), so no immediate concern.
C. Platelet count of 160,000/mm³: Normal range (150,000-400,000/mm³), so no immediate concern.
D. Hemoglobin of 6.2 g/dL: Normal hemoglobin levels are 13.5-17.5 g/dL (males) and 12-15.5 g/dL (females). A hemoglobin of 6.2 g/dL is critically low, indicating severe anemia, blood loss, or bone marrow suppression, which may require blood transfusion or further investigation.
Correct Answer is D
Explanation
A. Neuroleptic malignant syndrome: Causes fever, muscle rigidity, autonomic instability, and altered mental status-not dry mouth or blurry vision.
B. Teratogenicity: Refers to birth defects from medications taken during pregnancy.
C. Parkinson-like syndrome: Involves tremors, muscle rigidity, and bradykinesia-not dry mouth or blurry vision.
D. Anticholinergic effects: Symptoms of dry mouth, blurred vision, and urinary retention are classic signs of anticholinergic side effects caused by medications like antihistamines, tricyclic antidepressants, and some antipsychotics.
