A nurse is preparing to administer venlafaxine 75 mg PO to a client who has major depression. Available is venlafaxine 37.5 mg tablets. How many tablets should the nurse plan to administer? (Round to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["2"]
Step 1: Use the formula
Number of tablets = Desired dose ÷ Strength per tablet

Correct Answer is C
Explanation
Rationale:
A. In the moderate stage of Alzheimer's disease, clients typically exhibit persistent cognitive deficits, including memory loss, confusion, and difficulty performing basic ADLs without assistance. The scenario describes a client whose deficits are temporary and situation-dependent, which does not align with the consistent functional impairment seen in moderate Alzheimer's.
B. Severe Alzheimer's is characterized by profound cognitive and functional impairment, including inability to communicate, recognize family, or perform basic self-care. The client in this scenario returns to baseline when the stressor (family visit) is removed, indicating that their abilities are not permanently compromised, which excludes the severe stage.
C. Mild Alzheimer's disease often presents with subtle cognitive deficits that may be exacerbated by stress, fatigue, or environmental stimuli. Clients in this stage can perform most ADLs independently, but may require occasional assistance or monitoring in stressful or unfamiliar situations, as seen when the client becomes stressed during family visits but returns to baseline afterward. This pattern of situational impairment with preserved baseline function is typical of mild Alzheimer's.
D. The incipient stage refers to very early or preclinical changes, often without noticeable functional deficits. Clients in this stage may show minor memory lapses but can usually perform all ADLs without stress or intervention. The presence of stress-related functional deficits during family visits suggests the client has progressed beyond the incipient stage.
Correct Answer is ["15"]
Explanation
Step 1: Determine the concentration per mL
250 mg ÷ 5 mL = 50 mg/mL
Step 2: Use the formula
Volume (mL) = Desired dose ÷ Concentration per mL
Volume = 750 ÷ 50 = 15 mL
Final Answer: 15 mL
