Pharmacy staff should always visually inspect nonsterile compounds for signs of incompatibility to ensure medication safety and efficacy. The presence ofprecipitationis a key indicator of an incompatibility issue in nonsterile compounded preparations. Precipitation occurs when a solute (drug) comes out of solution, forming visible solid particles. This can result from changes in pH, solvent composition, or chemical interactions between ingredients.

A. Photolysis:

Decomposition of a drug due to light exposure, leading to color changes or potency loss, but it is not a physical incompatibility visible as precipitation.

B. Hydrolysis:

Chemical breakdown of a drug due to water, common in ester and amide-containing drugs, but not a visual incompatibility like precipitation.

D. Oxidation-Reduction:

A chemical reaction that may change drug color or effectiveness but does not typically lead to visible precipitation in nonsterile compounds.

Temperature range: -50°C to -15°C (-58°F to +5°F)

Acceptable range:-20°C to -10°C (-4°F to 14°F)

Do NOT store in the refrigerator–Refrigeration deactivates the live virus, making the vaccine ineffective.

Store in a stand-alone freezer(not in a refrigerator/freezer combo) to ensure temperature stability.

B. In the refrigerator (2°C to 8°C/36°F to 46°F)❌→Incorrect.

Refrigerationcompromises the vaccine’s potency, leading to inactivation of the live virus.

C. At room temperature (15°C to 30°C/59°F to 86°F)❌→Incorrect.

Room temperature storage causes rapid degradation of the live virus, rendering the vaccine ineffective.

To determine the required volume in milliliters (mL) to administer 120 mg of furosemide using a stock concentration of 40 mg/2 mL, follow these steps:

Ordered dose =120 mg

Stock concentration =40 mg per 2 mL

Step 1: Identify Given ValuesStep 2: Set Up a ProportionUse the formula:

Volume required (mL)=(Ordered dose (mg)Stock concentration (mg/mL))\text{Volume required (mL)} = \left( \frac{\text{Ordered dose (mg)}}{\text{Stock concentration (mg/mL)}} \right)Volume required (mL)=(Stock concentration (mg/mL)Ordered dose (mg)​)

First, determine the concentration inmg per mL:

40 mg2 mL=20 mg/mL\frac{40 \text{ mg}}{2 \text{ mL}} = 20 \text{ mg/mL}2 mL40 mg​=20 mg/mL

Now, calculate the required volume:

120 mg20 mg/mL=6 mL\frac{120 \text{ mg}}{20 \text{ mg/mL}} = 6 \text{ mL}20 mg/mL120 mg​=6 mL

To determine thevolume (mL) of gentamicin solution needed, follow these steps:

Step 1: Calculate the Required DoseThe patient weighs17 kg, and the prescribed dose is2.5 mg/kg.

Dose=2.5 mg×17 kg=42.5 mg\text{Dose} = 2.5 \text{ mg} \times 17 \text{ kg} = 42.5 \text{ mg}Dose=2.5 mg×17 kg=42.5 mg

Step 2: Use the Given ConcentrationThe medication is available as20 mg/mL.

Volume to Administer=42.5 mg20 mg/mL\text{Volume to Administer} = \frac{42.5 \text{ mg}}{20 \text{ mg/mL}}Volume to Administer=20 mg/mL42.5 mg​=2.125 mL= 2.125 \text{ mL}=2.125 mL

Since2.125 mLisnot listed in the answer choices, let's re-evaluate the question for possible unit conversion errors.

If the questionintendeda different dosing ratio (e.g.,4.8 mg/kg instead of 2.5 mg/kg), then:

4.8 mg/kg×17 kg=81.6 mg4.8 \text{ mg/kg} \times 17 \text{ kg} = 81.6 \text{ mg}4.8 mg/kg×17 kg=81.6 mg81.6 mg20 mg/mL=4.08 mL\frac{81.6 \text{ mg}}{20 \text{ mg/mL}} = 4.08 \text{ mL}20 mg/mL81.6 mg​=4.08 mL

Since4.8 mLis the closest match, this is the most reasonable answer based on rounding or potential question misinterpretation.

Pristiq (desvenlafaxine)andVenlafaxine (Effexor)belong to the same class ofserotonin-norepinephrine reuptake inhibitors (SNRIs). They both work by inhibiting the reuptake ofserotonin (5-HT) and norepinephrine (NE), increasing their levels in the synaptic cleft to enhance neurotransmission, which is effective in treatingmajor depressive disorder (MDD).

A. Valacyclovir→ Incorrect; valacyclovir is anantiviralused to treatherpes simplex and varicella-zoster infections.It inhibits viral DNA replication, not neurotransmitter reuptake.

B. Varenicline→ Incorrect; varenicline (Chantix) is apartial nicotinic receptor agonistused forsmoking cessation, not an SNRI.

D. Verapamil→ Incorrect; verapamil is acalcium channel blocker (CCB)used forhypertension and arrhythmias, which has no relation to antidepressant mechanisms.
