A nurse is assessing the fontanels of an 8-month-old infant.
Which of the following findings should the nurse recognize as an expected finding?

Choice A rationale:
Contractures are a risk for this client due to the lack of movement and constant positioning on one side. Contractures occur when the muscles, tendons, or ligaments shorten and tighten, limiting range of motion and flexibility. This can be a result of prolonged immobility or lack of use of the muscles.
Choice B rationale:
Calcium resorption is not a risk for this client. Calcium resorption refers to the process where bone tissue is broken down and calcium is released into the bloodstream. This process is not directly related to immobility or multiple sclerosis.
Choice C rationale:
Hypocalcemia, or low calcium levels in the blood, is also not a direct risk for this client. While immobility can lead to bone loss over time, it does not directly cause hypocalcemia.
Choice D rationale:
Diarrhea is not a risk for this client based on the information provided. Diarrhea can be a symptom of many conditions but there is no indication in the scenario that this client is at risk.
Choice E rationale:
Urinary stasis is a risk for this client due to their immobility. When a person is immobile, urine can pool in the bladder, creating an environment where bacteria can grow, potentially leading to urinary tract infections.

Choice F rationale:
Hypertension, or high blood pressure, is not a direct risk for this client based on the information provided. While chronic diseases like multiple sclerosis can indirectly contribute to hypertension through stress or medication side effects, it’s not directly caused by immobility or multiple sclerosis.

Choice G rationale:

Pressure injury is a significant risk for this client due to their constant positioning on one side and refusal to change positions. Pressure injuries occur when there is prolonged pressure on one area of the body, restricting blood flow and leading to tissue damage and necrosis.

Choice H rationale:

Atelectasis, or collapse of part of the lung, is also a risk for this client due to their immobility. When a person is immobile, they may take shallow breaths which do not fully inflate the lungs, leading to areas of collapse.

Choice A rationale:

Choosing a palpable and straight vein is essential for a successful IV insertion. A vein that is easily palpable and visible helps ensure that the catheter can be inserted smoothly, reducing the risk of complications such as infiltration or extravasation. Additionally, selecting a straight vein makes the insertion process easier and less painful for the client.

Choice B rationale:

Selecting a site on the client's dominant arm is not a requirement for IV insertion. The choice of arm depends on the individual client's condition, vein accessibility, and the healthcare provider's preference. Both arms can be used for IV insertion based on the client's specific needs.

Choice C rationale:

Applying a tourniquet below the venipuncture site helps distend the veins, making them more visible and accessible. This technique can aid in locating suitable veins for insertion. However, it is crucial to release the tourniquet once the vein is accessed to prevent complications such as thrombosis or hematoma.

Choice D rationale:

Elevating the client's arm prior to insertion can cause veins to collapse, making it more challenging to insert the IV catheter. Gravity can assist in distending the veins, so the arm should be positioned at or slightly below the level of the heart during IV insertion to maintain adequate blood flow.
