A nurse is preparing regular and NPH insulin in the same syringe for a client who has diabetes mellitus.
Which of the following actions should the nurse take?
Administer the mixture within 5 minutes of preparing it.
Inject air into the regular insulin vial before injecting air into the NPH vial.
Withdraw the NPH insulin before the regular insulin.
Shake both insulin vials for 2 minutes before withdrawing the doses.
The Correct Answer is A
Choice A rationale
Regular insulin is a rapid-acting insulin, and NPH is an intermediate-acting insulin. When mixed in the same syringe, the regular insulin molecules can bind to the protamine in the NPH suspension. This can alter the absorption profile of the regular insulin, delaying its onset of action. Administering the mixture within 5 minutes prevents this molecular interaction and ensures the regular insulin retains its rapid-acting properties.
Choice B rationale
It is crucial to inject air into the NPH insulin vial first, followed by the regular insulin vial, and then withdraw the regular insulin dose before the NPH. This specific order prevents the NPH from contaminating the regular insulin vial with protamine, which would alter the potency and action profile of the regular insulin for future use. The regular insulin is then drawn up first.
Choice C rationale
The correct procedure is to withdraw the regular insulin before the NPH insulin. The sequence is to inject air into both vials, then draw up the clear, rapid-acting regular insulin first, followed by the cloudy, intermediate-acting NPH insulin. This sequence is essential to prevent contamination of the regular insulin vial with the NPH insulin, which could affect its rapid-acting properties.
Choice D rationale
Shaking insulin vials is generally discouraged as it can lead to the formation of air bubbles, which can result in an inaccurate dose. Instead of shaking, the NPH insulin vial should be gently rolled between the palms of the hands. This action warms the insulin and resuspends the particles uniformly without causing bubbles, ensuring an accurate and consistent dose is administered. .

Correct Answer is A
Explanation
Choice A rationale
Based on the client's statements, there is strong evidence of neglect and potential exploitation. Neglect is indicated by the inadequate food supply and minimal meal preparation. Financial exploitation is suggested by the client's lack of access to their retirement income, despite it being used for their care. This situation poses a serious risk to the client's well-being, triggering the nurse's ethical and legal duty to report suspected elder abuse to the appropriate authorities.
Choice B rationale
While gathering more information is often a good practice, directly questioning the adult child about financial matters could escalate the situation and potentially put the client at further risk. The primary responsibility of the nurse in this scenario is to ensure the client's safety, and the existing information is sufficient to warrant a report. The client has already provided a detailed account of the financial arrangement and their lack of access to funds, which is a key indicator of exploitation.
Choice C rationale
Educating the adult child about nutrition, while potentially helpful in some circumstances, does not address the immediate and serious issues of neglect and financial exploitation. The client's safety is the priority. Focusing solely on education ignores the broader pattern of abuse and the client's vulnerability, which requires a more direct and protective intervention.
Choice D rationale
Encouraging the client to speak with their adult child may place them in a more vulnerable position and could increase the risk of retaliation or further neglect. The client has already expressed an understanding of their adult child's frustration, and this approach fails to address the power imbalance and exploitative nature of the relationship. It is not an appropriate or safe intervention in a situation of suspected abuse. *.
Correct Answer is A
Explanation
Choice A rationale
Chills are a systemic manifestation of an infectious process and are commonly associated with endometritis. Endometritis is an infection of the uterine lining, which can cause a systemic inflammatory response. This response often includes fever and chills, as the body's immune system fights the invading pathogens, causing a thermoregulatory cascade. A temperature of 100.4°F (38°C) or higher is typical.
Choice B rationale
Back pain can occur with various postpartum conditions, but it is not a primary or specific finding for endometritis. While uterine cramping and pelvic pain are characteristic due to the uterine inflammation, back pain is not as specific. More classic signs are fever, lower abdominal pain, uterine tenderness, and foul-smelling lochia due to the presence of bacteria.
Choice C rationale
Tachycardia, not bradycardia, is an expected finding in a client with endometritis. Tachycardia is a physiological response to fever, infection, and the systemic inflammatory process. The heart rate increases to compensate for increased metabolic demand and to circulate immune cells more efficiently. Bradycardia would be an unusual and unexpected finding.
Choice D rationale
Agitation is not a primary or typical finding of endometritis. Endometritis is a physical infection of the uterine lining. While discomfort and fever may cause irritability, agitation is not a specific expected symptom. This finding is more associated with neurological or psychiatric conditions, or severe complications like septic shock, which is a more advanced state. *.
