Question 1 of 5
What is the immediate consequence of the activation of beta receptors in the 9-year-old boy with mild asthma?
Correct Answer: B
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 2 of 5
Which of the following drugs was the most potent based on the effective dose that produces a response in 50% of subjects?
Correct Answer: D
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 3 of 5
All of the following can be advantages to IV administration except?
Correct Answer: A
Rationale: Step 1: IV administration bypasses the need for patient compliance with oral medications. Step 2: Patients do not need to remember to take medications at specific times. Step 3: Improved patient compliance is not an advantage of IV administration. Step 4: Commercial availability, increased onset of action, and increased bioavailability are benefits. Step 5: Therefore, the correct answer is A: Improved patient compliance is not an advantage of IV administration. Summary: IV administration offers benefits like quick onset of action, high bioavailability, and availability of products, but it does not improve patient compliance since it does not require patients to remember to take medications orally.
Question 4 of 5
Which cellular structure stores hormones and other substances?
Correct Answer: A
Rationale: The correct answer is A: Golgi apparatus. The Golgi apparatus is responsible for modifying, sorting, and packaging proteins and other substances for secretion or for use within the cell. It stores hormones and other substances before they are secreted or transported to other parts of the cell. Endoplasmic reticulum (B) is involved in protein synthesis, not storage. Mitochondria (C) are the powerhouse of the cell, generating energy. Lysosomes (D) contain enzymes for digesting waste materials, not for storage. Therefore, the Golgi apparatus is the correct choice for storing hormones and other substances.
Question 5 of 5
An older adult client has an elevated serum creatinine level. This client is at greatest risk for which medication-related effect?
Correct Answer: A
Rationale: The correct answer is A: Toxicity. Elevated serum creatinine level indicates impaired kidney function, leading to decreased drug clearance. This increases the risk of drug accumulation and toxicity in the body. Increased absorption (B) is not directly related to elevated creatinine levels. Delayed gastric emptying (C) affects drug absorption in the stomach, not clearance. Idiosyncratic effects (D) are unpredictable reactions unrelated to creatinine levels. Therefore, toxicity is the greatest risk due to impaired drug clearance in older adults with elevated serum creatinine levels.
