The nurse calculates that a patient must receive 1.3 mL of an anti-infective agent. The dose is ordered IM. Which of the following choices demonstrates safe, evidence-based practice?
23g 1 in (2.54 cm) needle to the right deltoid. Use the acromion process as a landmark.
25g 0.5 in (1.3 cm) long needle to the left rectus femoris. Aspirate prior to injection.
27g 1.5 in (3.8 cm) long needle to the left vastus lateralis area. Massage area wearing clean gloves after injection.
21g 1.5 in (3.8 cm) needle to the right ventrogluteal area. Use Z-track technique.
The Correct Answer is D
Choice D Reason: 21g 1.5 in (3.8 cm) needle to the right ventrogluteal area. Use Z-track technique.
Choice A Reason:
Using a 23-gauge, 1-inch needle for an intramuscular (IM) injection in the deltoid muscle is generally appropriate for adults. The deltoid muscle is a common site for IM injections, especially for small volumes of medication (up to 2 mL). The acromion process is a correct landmark for locating the deltoid muscle. However, the deltoid muscle is not the best site for larger volumes or more viscous medications. Additionally, the needle length might not be sufficient for individuals with more subcutaneous fat, potentially leading to suboptimal medication delivery.
Choice B Reason:
A 25-gauge, 0.5-inch needle is typically used for subcutaneous injections rather than intramuscular injections. The rectus femoris muscle can be used for IM injections, but it is not the preferred site due to the potential for increased pain and discomfort. Aspiration before injection is a debated practice; current guidelines suggest that aspiration is not necessary for most IM injections, except when injecting into the dorsogluteal site, which is not recommended due to the risk of hitting the sciatic nerve.
Choice C Reason:
A 27-gauge, 1.5-inch needle is appropriate for IM injections, and the vastus lateralis is a suitable site, especially for infants and young children. However, massaging the injection site after administering an IM injection is not recommended. Massaging can cause the medication to disperse into the subcutaneous tissue, reducing its effectiveness and potentially causing irritation or bruising.
Choice D Reason:
Using a 21-gauge, 1.5-inch needle for an IM injection in the ventrogluteal area is considered safe and effective. The ventrogluteal site is preferred for IM injections because it is free from major nerves and blood vessels, reducing the risk of injury. The Z-track technique is used to prevent medication from leaking into the subcutaneous tissue, ensuring that it remains in the muscle for proper absorption. This technique is particularly useful for medications that can stain or irritate the skin and subcutaneous tissue.

Correct Answer is D
Explanation
Choice A Reason:
“You should share this thought with your psychiatrist.”
This response suggests that the client should discuss their harmful thoughts with their psychiatrist. While it is important for the client to communicate openly with their mental health provider, this response does not directly address the nurse’s ethical and legal obligation to report threats of harm. The nurse has a duty to ensure the safety of others, and simply redirecting the client to another professional does not fulfill this responsibility. According to the Tarasoff rule, healthcare providers have a duty to warn potential victims if a client poses a credible threat.
Choice B Reason:
“I can make that promise to you based on nurse-client privilege.”
This statement is incorrect because nurse-client privilege does not extend to situations where there is a threat of harm to others. Confidentiality in healthcare is crucial, but it has limits, especially when it comes to preventing harm. Nurses are legally and ethically obligated to report any threats of violence or harm to appropriate authorities to protect potential victims. Making such a promise would be misleading and could result in serious consequences.
Choice C Reason:
“Those kinds of thoughts will make your hospitalization longer.”
This response is inappropriate as it focuses on the potential consequences for the client rather than addressing the immediate concern of a threat to another person’s safety. It may also discourage the client from being honest about their thoughts in the future. The primary responsibility of the nurse in this situation is to ensure the safety of the client and others, which involves reporting the threat to the appropriate authorities.
Choice D Reason:
“I cannot promise that. Confidentiality does not include plans to hurt others.”
This is the correct response. It clearly communicates to the client that while confidentiality is important, it does not cover plans to harm others. The nurse must explain that they are obligated to report any threats of violence to ensure the safety of potential victims. This response aligns with legal and ethical guidelines, which mandate that healthcare providers report credible threats of harm.
Correct Answer is ["A","C","D"]
Explanation
Choice A Reason:
Use a calm voice.
Using a calm voice is essential in de-escalating an agitated client. A calm and steady tone can help soothe the client and reduce their anxiety. It also demonstrates that the nurse is in control of the situation and is there to help, which can be reassuring for the client.
Choice B Reason:
Speak louder than the client so as to be heard.
Speaking louder than the client is not appropriate as it can escalate the situation further. Raising one’s voice can be perceived as confrontational and may increase the client’s agitation. It is important to maintain a calm and composed demeanor to help de-escalate the situation.
Choice C Reason:
Reduce stimuli for the client.
Reducing stimuli is an effective intervention for an agitated client. Excessive noise, bright lights, and other environmental stimuli can exacerbate agitation. Creating a quieter and more controlled environment can help the client feel more at ease and reduce their agitation.
Choice D Reason:
Attempt to redirect the client.
Attempting to redirect the client can be helpful in de-escalating agitation. Redirecting the client’s attention to a different topic or activity can help distract them from the source of their agitation and provide a sense of control. This technique can be effective in calming the client and preventing further escalation.
Choice E Reason:
Reprimand the client for upsetting everyone.
Reprimanding the client is not an appropriate intervention. It can increase the client’s feelings of frustration and agitation. Instead, the focus should be on understanding the client’s needs and providing support to help them calm down.
