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.
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 C
Explanation
Choice A rationale:
While providing meticulous oral care and allowing ice chips for dry mouth can promote comfort, it does not address the primary concern of absent bowel sounds.
Ice chips could potentially stimulate bowel activity, but this is not a reliable or recommended method for managing absent bowel sounds in the immediate postoperative period.
It's essential to prioritize actions that assess and address the potential causes of absent bowel sounds, as they can indicate serious complications.
Choice B rationale:
Notifying the surgeon immediately and preparing for emergency surgery is not the appropriate first course of action in this situation.
Emergency surgery would be considered only if there were clear signs of a life-threatening complication, such as bowel perforation or peritonitis.
These complications would typically present with additional symptoms such as severe abdominal pain, fever, and hemodynamic instability.
Absent bowel sounds alone, without other concerning signs, do not warrant immediate surgical intervention.
Choice D rationale:
Allowing the patient to have clear liquids as tolerated is not appropriate when bowel sounds are absent. Introducing oral intake before bowel function has returned can increase the risk of nausea, vomiting, and aspiration.
It's crucial to wait for the return of bowel sounds before initiating oral intake to ensure proper digestion and minimize complications.
Choice C rationale:
Keeping the patient NPO (nothing by mouth) is the most appropriate action when bowel sounds are absent after major abdominal surgery.
This allows the bowel to rest and recover from the surgical manipulation.
It also prevents potential complications such as aspiration and nausea/vomiting that could arise from premature oral intake.
Documenting the absence of bowel sounds in the patient's medical record is essential for communication among healthcare providers and for monitoring the patient's progress.
This documentation provides a clear record of the patient's clinical status and facilitates appropriate decision-making regarding further interventions.
Correct Answer is B
Explanation
Choice A rationale:
Echinacea: It has anti-inflammatory properties and is not typically associated with exacerbating rheumatoid arthritis symptoms. Studies have shown potential benefits in reducing inflammation, including evidence of possible effectiveness for osteoarthritis and rheumatoid arthritis. However, more research is needed to confirm its efficacy and safety in rheumatoid arthritis.
Choice B rationale:
Turmeric:
Curcumin, the active component of turmeric, has both anti-inflammatory and pro-inflammatory effects.
While it has potential benefits for some inflammatory conditions, it can also stimulate the immune system, which could worsen rheumatoid arthritis symptoms in certain individuals.
Studies have shown mixed results, with some indicating potential benefits and others suggesting a possible worsening of symptoms.
Due to this uncertainty, caution is advised, and patients with rheumatoid arthritis should consult with their healthcare providers before using turmeric supplements.
Choice C rationale:
Ginger: It has well-documented anti-inflammatory properties and is not known to exacerbate rheumatoid arthritis symptoms.
Studies have shown ginger to be potentially effective in reducing pain and inflammation in individuals with rheumatoid arthritis.
It is generally considered safe for use in this population.
Choice D rationale:
Valerian: It is a herb primarily used for its sedative and sleep-promoting effects.
It has not been shown to have any significant impact on inflammation or rheumatoid arthritis symptoms. There is no evidence to suggest that it would worsen the condition.
