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 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.
Correct Answer is C
Explanation
This is because coarctation of the aorta is a congenital condition where the aorta is narrow, usually in the area where the ductus arteriosus inserts. This causes a decrease in blood flow to the lower body, resulting in weak or absent pulses in the femoral arteries.
The other choices are incorrect for the following reasons:
- Choice A, frequent nosebleeds, is not a typical sign of coarctation of the aorta.
Nosebleeds can be caused by many factors, such as dry air, allergies, trauma, or bleeding disorders.
- Choice B, upper extremity hypotension, is also not a common finding in coarctation of the aorta. In fact, patients with this condition may have high blood pressure in the upper extremities due to the increased resistance of the narrowed aorta.
- Choice D, increased intracranial pressure, is not directly related to coarctation of the aorta.
Increased intracranial pressure can be caused by various conditions that affect the brain, such as head injury, stroke, infection, or tumor.
Normal ranges for blood pressure and pulse vary depending on age, sex, and health status.
However, some general guidelines are:
- Blood pressure: less than 120/80 mmHg for adults; less than 95/65 mmHg for infants.
- Pulse: 60 to 100 beats per minute for adults; 100 to 160 beats per minute for infants.
