A nurse is teaching a client who has a pelvic fracture about the manifestations of fat embolism syndrome. The nurse should include which of the following findings as an early manifestation?
Hypertension
Swollen calf
Tachypnea
Bradycardia
The Correct Answer is C
Choice A reason:
Hypertension is not typically an early manifestation of fat embolism syndrome (FES). FES is more commonly associated with hypoxemia, which can lead to hypotension rather than hypertension².
Choice B reason:
While a swollen calf may indicate deep vein thrombosis, it is not an early sign of FES. FES primarily affects the lungs and neurological systems early on, rather than causing localized swelling such as in a calf².
Choice C reason:
Tachypnea, or rapid breathing, is indeed an early sign of FES. This symptom usually develops before others and is due to the fat globules causing respiratory distress by blocking the pulmonary microcirculation²³⁴.
Choice D reason:
Bradycardia, or a slower than normal heart rate, is not an early sign of FES. Instead, patients may experience tachycardia as a response to hypoxemia and respiratory distress².

Correct Answer is D
Explanation
Choice A reason:
Immunoglobulin G (IgG) is the most common type of antibody found in blood circulation and is involved in the body's immune response to fight infections. However, IgG is not typically associated with allergic reactions, which are immediate hypersensitivity reactions.
Choice B reason:
Immunoglobulin A (IgA) plays a critical role in mucosal immunity and is found in high concentrations in the mucous membranes, particularly those lining the respiratory passages and gastrointestinal tract. Like IgG, IgA is not primarily responsible for the allergic response seen in conditions such as seasonal allergies.
Choice C reason:
Immunoglobulin M (IgM) is usually the first antibody produced by the immune system when it detects an infection. IgM antibodies are larger and are involved in the primary immune response but are not the antibodies that mediate typical allergic reactions.
Choice D reason:
Immunoglobulin E (IgE) is the antibody that plays a central role in the pathophysiology of allergic diseases, including seasonal allergies. IgE antibodies are produced as a response to allergens and are responsible for the symptoms of an allergic reaction. An elevation in IgE levels typically indicates a positive result for an allergy test such as RAST.
Correct Answer is D
Explanation
Choice A reason:
Dyspepsia, commonly known as indigestion, is not typically associated with SIADH. It is a condition characterized by chronic or recurrent pain in the upper abdomen and is not linked to the overproduction of antidiuretic hormone.
Choice B reason:
Osteoarthritis is a degenerative joint disease and does not cause SIADH. It is characterized by the breakdown of joint cartilage and underlying bone, most commonly from middle age onward, causing pain and stiffness, especially in the hip, knee, and thumb joints.
Choice C reason:
Liver cirrhosis can lead to complications that may contribute to fluid imbalance, but it is not a direct cause of SIADH. SIADH is more commonly associated with conditions that affect the central nervous system or certain types of cancer.
Choice D reason:
Lung cancer, particularly small cell lung cancer, is a well-known cause of SIADH. Tumors in the lungs can produce and release antidiuretic hormone independently, leading to the syndrome of inappropriate antidiuretic hormone secretion.
