A patient has an order for a subcutaneous injection of insulin.
Into which of the following tissues will the nurse prepare to give this injection?

Into the patient’s intravenous line.

Into the patient’s vastus lateralis.

Into the fatty tissue of the patient’s abdomen.

Into the patient’s deltoid.

Answer and Explanation

The Correct Answer is C

Choice A rationale:

Intravenous (IV) administration delivers medication directly into the bloodstream. This route is not appropriate for insulin because it would result in a rapid and potentially dangerous drop in blood glucose levels. Insulin needs to be absorbed more slowly to mimic the natural release of insulin from the pancreas.

IV administration also requires sterile technique and specialized equipment, making it more complex and time-consuming than subcutaneous injection.

Additionally, there is a higher risk of infection and other complications with IV administration.

Choice B rationale:

The vastus lateralis is a muscle in the thigh that is commonly used for intramuscular (IM) injections. However, IM injections are not typically used for insulin administration because they can be more painful and have a slower absorption rate than subcutaneous injections.

IM injections also carry a higher risk of hitting a blood vessel, which could lead to erratic absorption of insulin.

Choice D rationale:

The deltoid is a muscle in the upper arm that can be used for subcutaneous injections. However, the abdomen is generally the preferred site for insulin injection because it has a greater amount of subcutaneous fat, which helps to slow the absorption of insulin and provide a more consistent effect.

The abdomen is also a more convenient site for self-injection, as it is easily accessible.

Choice C rationale:

The fatty tissue of the abdomen is the ideal site for subcutaneous insulin injection because it provides slow and consistent absorption of insulin.

The abdomen has a rich blood supply, which helps to distribute the insulin throughout the body.

The subcutaneous tissue in the abdomen is relatively thin, which makes it easy to inject insulin without causing pain or discomfort.

The abdomen is also a large area, which allows for multiple injection sites to be used and rotated to prevent lipohypertrophy (thickening of the subcutaneous tissue).

Correct Answer is ["A","B","C"]

Explanation

Choice A rationale:

Splinting the incision when coughing helps to minimize pain and discomfort, which can encourage deeper breathing and coughing. This is essential because deep breathing and coughing help to clear secretions from the lungs and prevent atelectasis (collapse of lung tissue).

Steps for splinting the incision:

Place a pillow or folded towel over the incision site.

Instruct the patient to apply gentle pressure to the pillow or towel with their hands when coughing or deep breathing. Encourage the patient to relax their abdominal muscles during coughing and deep breathing exercises.

Choice B rationale:

Sitting up in a chair and ambulating promote lung expansion and help to mobilize secretions. This is because gravity assists in moving secretions from the smaller airways into the larger airways, where they can be more easily coughed up.

Additional benefits of sitting up and ambulating: Improved circulation

Decreased risk of pneumonia Enhanced recovery from surgery Choice C rationale:

Using an incentive spirometer hourly helps to increase lung capacity and prevent atelectasis. The device encourages the patient to take slow, deep breaths, which helps to inflate the alveoli (air sacs) in the lungs.

Instructions for using an incentive spirometer:

Sit upright in a chair or bed.

Place the mouthpiece of the spirometer in your mouth and seal your lips around it.

Inhale slowly and deeply through the mouthpiece, aiming to raise the piston inside the device as high as possible. Hold your breath for 3-5 seconds.

Exhale slowly and completely through the mouthpiece.

Repeat the process 10-15 times per hour, or as instructed by your healthcare provider.

A. “Herbal supplements are derived from plant materials, hence they are organic and non-toxic.” B. “Herbal supplements are generally less costly than prescription medications.” C. “Herbal supplements are not subject to the same stringent quality standards as prescription medications.” D. “The convenience of herbal supplements is that they can be procured without a prescription.”

Correct Answer is C

Explanation

Choice A rationale:

Inaccurate statement: While herbal supplements are derived from plant materials, this does not inherently guarantee their safety or non-toxicity. Some plants contain potent compounds that can have adverse effects, even in small doses.

Lack of regulation: Herbal supplements are not regulated by the FDA in the same way as prescription medications. This means that there is no guarantee of their purity, potency, or consistency.

Potential for interactions: Herbal supplements can interact with prescription medications, potentially leading to harmful side effects.

Choice B rationale:

Cost-related issue: The cost of herbal supplements can vary widely. While some may be less expensive than prescription medications, others can be quite costly.

Misleading focus: Emphasizing cost as a primary factor could lead patients to prioritize affordability over safety and effectiveness.

Choice C rationale:

Addresses quality concerns: This response directly addresses the lack of stringent quality standards for herbal supplements, highlighting a significant safety concern.

Encourages informed decision-making: This response encourages patients to carefully consider the potential risks and benefits of herbal supplements, prompting them to seek reliable information and discuss their choices with healthcare providers.

Choice D rationale:

Convenience vs. safety: While the convenience of herbal supplements may be appealing, this response does not address the potential safety concerns associated with their use.

Potential for misuse: Highlighting convenience could lead to patients using herbal supplements inappropriately or without necessary guidance from healthcare professionals.
