The order is Ampicillin 1.5 grams added to 100mL of Normal Saline, infuse over 120 minutes. Drop Factor is 60gtt/mL. Available from pharmacy is Ampicillin 500mg in 10mL vial. Calculate the flow rate in gtt/min in which the IV fluid is to flow.
The Correct Answer is ["65"]
Here are the steps to calculate the flow rate in gtt/min:
Step 1: Calculate the total volume of fluid to be infused.
The order is for 1.5 grams of Ampicillin added to 100 mL of Normal Saline, so the total volume is 100 mL. Step 2: Calculate the number of vials of Ampicillin needed.
Each vial contains 500 mg of Ampicillin, and the order is for 1.5 grams (which is 1500 mg). Therefore, you will need 3 vials of Ampicillin (1500 mg ÷ 500 mg/vial = 3 vials). Step 3: Calculate the total volume of Ampicillin solution.
Each vial contains 10 mL of Ampicillin solution, and you need 3 vials.
Therefore, the total volume of Ampicillin solution is 30 mL (3 vials × 10 mL/vial = 30 mL). Step 4: Calculate the total volume to be infused, including the Ampicillin solution. The total volume is 100 mL of Normal Saline + 30 mL of Ampicillin solution = 130 mL. Step 5: Calculate the infusion time in minutes.
The order is to infuse over 120 minutes.
Step 6: Calculate the flow rate in gtt/min.
Use the formula: Flow rate (gtt/min) = Total volume (mL) × Drop factor (gtt/mL) ÷ Infusion time (min) Plug in the values: Flow rate = 130 mL × 60 gtt/mL ÷ 120 min
Simplify: Flow rate = 7800 ÷ 120
Flow rate = 65 gtt/min
Therefore, the flow rate in gtt/min in which the IV fluid is to flow is 65 gtt/min.

Correct Answer is C
Explanation
Rationale for Choice A:
Sims' position is a side-lying position with the lower arm and leg flexed and the upper arm and leg extended. It is not ideal for bladder scanning because it can displace the bladder and potentially lead to inaccurate readings. While it can be used for other purposes, such as inserting rectal suppositories or performing vaginal exams, it's not the optimal choice for bladder scanning.
Rationale for Choice B:
Dorsal recumbent position is a supine position with the knees bent and feet flat on the bed. While it provides some exposure of the bladder, it may not fully visualize the entire bladder due to potential compression from the abdominal contents. This can also result in inaccurate readings.
Rationale for Choice D:
High Fowler's position is a semi-sitting position with the head of the bed elevated at a 45- to 60-degree angle. This position is not suitable for bladder scanning because it can cause the bladder to shift upward and out of the optimal scanning range. It's typically used for respiratory comfort and procedures involving the head and upper body.
Rationale for Choice C:
Supine position is the best position for bladder scanning because it allows for the most accurate visualization of the bladder. In this position, the patient lies flat on their back with their legs extended. This position allows the bladder to rest naturally in the pelvic cavity, ensuring optimal positioning for the bladder scanner to capture a clear image and provide an accurate measurement of bladder volume. It also promotes patient comfort and relaxation during the procedure.
Correct Answer is A
Explanation
Choice A rationale:
The physical dimension encompasses the tangible, biological aspects of an individual, including age, race, gender, genetic inheritance, anatomy, and physiological processes.
Here's a detailed breakdown of how each of these factors aligns with the physical dimension in the context of the patient's hypertension:
Age:
Hypertension is more prevalent in older adults due to natural changes in the cardiovascular system, such as stiffening of arteries and decreased elasticity.
The patient's age of 68 years places him within this higher-risk category.
Race:
African Americans have a disproportionately higher risk of hypertension and related complications compared to other racial groups.
This disparity is attributed to a complex interplay of genetic, environmental, and socioeconomic factors. Gender:
While both men and women experience hypertension, men tend to develop it earlier in life and have a higher lifetime risk.
This difference is partially due to hormonal influences and lifestyle factors.
Genetic inheritance:
Hypertension often has a significant genetic component.
Individuals with a family history of hypertension are more likely to develop the condition themselves, suggesting a role of inherited genes in blood pressure regulation.
Choice B rationale:
The emotional dimension focuses on psychological and mental aspects, including feelings, thoughts, behaviors, and coping mechanisms.
While emotions can certainly influence blood pressure and overall health, they are not directly categorized under the physical dimension in this context.
Choice C rationale:
The environmental dimension addresses external factors that impact health, such as access to healthcare, social support, exposure to pollutants, and community resources.
While these factors can indirectly contribute to hypertension risk, they are not inherent physical characteristics of the individual.
Choice D rationale:
The holistic dimension encompasses a comprehensive view of health, integrating physical, emotional, spiritual, social, and environmental aspects.
While holistic care is essential for managing hypertension, the question specifically asks about the dimension that age, race, gender, and genetic inheritance exemplify, which is most accurately aligned with the physical dimension.
