Which needle gauge should a nurse select when administering a medication subcutaneously?
8.
20.
21.
25.
The Correct Answer is D
The needle gauge size for subcutaneous injections should be between 25 and 31, depending on the patient’s size and the viscosity of the medication.
A smaller gauge number means a larger diameter needle, which can cause more pain and tissue damage.
Choice A is wrong because 8 is too large for subcutaneous injections and can cause bleeding and bruising.
Choice B is wrong because 20 is also too large for subcutaneous injections and can cause similar complications as choice A.
Choice C is wrong because 21 is still too large for subcutaneous injections and can cause discomfort and injury to the patient.
The needle length for subcutaneous injections should be between ½ inch and ⅝ inch, depending on the amount of subcutaneous tissue present. The nurse should pinch the skin and insert the needle at a 45-degree angle to ensure proper delivery of the medication.

Correct Answer is D
Explanation
This is because a client who has been diaphoretic for the past six hours is likely to have wet and uncomfortable bed linens that can cause skin breakdown and infection. Changing the bed linens frequently can help keep the client dry and comfortable.
Choice A is wrong because offering the client a bedpan every three hours is not related to diaphoresis.
The client may or may not need to use the bedpan depending on their fluid intake and output.
Choice B is wrong because keeping an emesis basin near the bedside is not related to diaphoresis.
The client may or may not need to vomit depending on their underlying condition.
Choice C is wrong because providing oral care every four hours is not enough for a client who has been diaphoretic for the past six hours. The client may have dry mouth and dehydration due to excessive sweating and may need more frequent oral care and hydration.
Correct Answer is B
Explanation
The nurse should make the statement “The client has hypoxemia after 10 minutes on a rebreather mask.” first. This is because SBAR (Situation- Background-Assessment-Recommendation) is a communication tool that helps provide essential, concise information, usually during crucial situations. The first component of SBAR is Situation, which is a concise statement of the problem.
The nurse should state the most urgent and relevant problem first, which is the client’s hypoxemia.
Choice A is wrong because it is not a clear statement of the situation.
It is vague and does not provide specific information about the client’s condition or vital signs.
It also expresses the nurse’s feeling rather than an objective assessment.
Choice C is wrong because it is part of the Assessment component of SBAR, not the Situation.
It provides numerical data about the client’s blood gas analysis, but it does not state the problem or the reason for calling the healthcare provider.
Choice D is wrong because it is part of the Background component of SBAR, not the Situation.
It provides pertinent and brief information related to the situation, such as the client’s medical history and diagnosis, but it does not state the current problem or concern.
Normal ranges for blood gas analysis are:
- PaO2: 80-100 mmHg
- PaCO2: 35-45 mmHg
- HCO3: 22-26 mEq/L
Hypoxemia is defined as a low level of oxygen in the blood, usually below 60 mmHg.
