A nurse is preparing to insert an IV catheter for a client.
Which of the following actions should the nurse plan to take?
Select a site on the client’s dominant arm
Apply a tourniquet below the venipuncture site
Elevate the client’s arm prior to insertion
Choose a vein that is palpable and straight
The Correct Answer is D
The correct answer is choice D. The nurse should choose a vein that is palpable and straight for IV catheter insertion.
This will facilitate the insertion of the catheter and reduce the risk of complications such as infiltration, phlebitis, or hematoma. A straight vein will also allow the catheter to be inserted up to the hub, which reduces the risk of contamination along the length of the catheter.
Choice A is wrong because selecting a site on the client’s dominant arm can interfere with the client’s mobility and increase the risk of dislodging the catheter. The nurse should choose a site on the client’s non-dominant arm, preferably on the hand or forearm.
Choice B is wrong because applying a tourniquet below the venipuncture site will impede blood flow and make it harder to locate a suitable vein. The nurse should apply a tourniquet above the venipuncture site, about 10 to 15 cm from the insertion site.
Choice C is wrong because elevating the client’s arm prior to insertion will decrease venous filling and make it harder to palpate a vein. The nurse should lower the client’s arm below the level of the heart to increase venous distension.
Normal ranges for IV catheter size and insertion angle depend on several factors, such as the type and duration of therapy, the condition and size of the vein, and the age and preference of the client.
In general, smaller gauge catheters (20 to 24) are preferred for peripheral IV therapy, and larger gauge catheters (14 to 18) are used for rapid fluid administration or blood transfusion. The insertion angle can vary from 10 to 30 degrees, depending on the depth and location of the vein.

Correct Answer is C
Explanation
The correct answer is choice C. Taking a hot shower in the morning can help decrease stiffness and improve joint mobility for people with rheumatoid arthritis. This is one of the self-management strategies that can reduce pain and disability.
Choice A is wrong because applying cold packs directly on the skin of the affected joints can cause vasoconstriction and increase inflammation.
Cold therapy should be used with caution and with a barrier between the skin and the ice pack.
Choice B is wrong because biological response modifiers are not used to prevent infection, but to reduce inflammation and slow down joint damage in rheumatoid arthritis.
These medications can actually increase the risk of infection by suppressing the immune system.
Choice D is wrong because clustering physical activities during the day can cause fatigue and joint stress for people with rheumatoid arthritis.
It is better to pace activities throughout the day and take frequent breaks to rest the joints.
Normal ranges for rheumatoid arthritis are based on the disease activity score (DAS), which measures the number of swollen and tender joints, the level of inflammation in the blood, and the patient’s global assessment of health. A DAS below 2.6 indicates remission, a DAS between 2.6 and 3.2 indicates low disease activity, a DAS between 3.2 and 5.1 indicates moderate disease activity, and a DAS above 5.1 indicates high disease activity.
Correct Answer is A
Explanation
Choice A reason
The client is observed displaying a shuffling gait while walking in the hall is the correct answer. The nurse should recognize that observing a shuffling gait in a client who is taking antipsychotic medication is an adverse effect that must be reported to the healthcare provider. A shuffling gait is a movement disorder known as parkinsonism, which can be a side effect of some antipsychotic medications, particularly first-generation or typical antipsychotics.
Parkinsonism includes symptoms similar to Parkinson's disease, such as a shuffling walk, muscle stiffness, tremors, and difficulty with balance and coordination. It can occur as a result of blocking dopamine receptors in the brain, leading to an imbalance in dopamine levels.
Choice B reason:
The client mumbling quietly while alone is not correct because in the day room may be related to the symptoms of schizophrenia, and it does not indicate an adverse effect of the antipsychotic medication.
Choice C reason:
The client feeling light-headed when standing up quickly is not correct and it may be related to postural hypotension, which can be a side effect of some antipsychotic medications. While it should be monitored and reported if persistent or severe, it is not as urgent as reporting a shuffling gait.
Choice D reason:
The client stating that being in the sun hurts their eyes does not necessarily indicate an adverse effect of the antipsychotic medication. It may be related to other factors or unrelated to the medication.
