The nurse provides care for a client with a hemoglobin of 8 g/dL (80 g/L) due to acute blood loss. Which finding does the nurse expect to assess?
Shallow respirations and a smooth, beefy red tongue
Facial flushing with distended neck veins
Bilateral numbness and tingling of the extremities
Increased heart rate and decreased mental alertness
The Correct Answer is D
Choice A reason: Shallow respirations and a smooth, beefy red tongue are not the expected findings because they are signs of pernicious anemia, not acute blood loss. Pernicious anemia is a condition where the body cannot produce enough red blood cells due to a lack of vitamin B12, which is needed for DNA synthesis and cell division. Pernicious anemia can cause shallow respirations due to hypoxia, which is a low level of oxygen in the tissues, and a smooth, beefy red tongue due to atrophy of the tongue papillae, which are the small projections that give the tongue its rough texture.
Choice B reason: Facial flushing with distended neck veins are not the expected findings because they are signs of polycythemia, not acute blood loss. Polycythemia is a condition where the body produces too many red blood cells, which increases the blood volume and the blood viscosity, making the blood thicker and harder to flow. Polycythemia can cause facial flushing due to increased blood flow to the skin, and distended neck veins due to increased pressure in the venous system.
Choice C reason: Bilateral numbness and tingling of the extremities are not the expected findings because they are signs of peripheral neuropathy, not acute blood loss. Peripheral neuropathy is a condition where the nerves that carry signals from the brain and spinal cord to the rest of the body are damaged or impaired, causing sensory and motor disturbances. Peripheral neuropathy can cause bilateral numbness and tingling of the extremities due to reduced nerve conduction and sensation.
Choice D reason: Increased heart rate and decreased mental alertness are the expected findings because they are signs of acute blood loss. Acute blood loss is a condition where the body loses a large amount of blood in a short period of time, which reduces the oxygen-carrying capacity of the blood and the tissue perfusion. Acute blood loss can cause increased heart rate due to the compensatory mechanism of the body to increase the cardiac output and maintain the blood pressure, and decreased mental alertness due to the reduced oxygen delivery to the brain.

Correct Answer is C
Explanation
Choice A reason: Initiates the fibrinolytic process in the arteries is not a role of inflammation in the development of atherosclerosis, but a protective mechanism against it. Fibrinolysis is the breakdown of blood clots by enzymes such as plasmin. It prevents the formation of thrombi that can occlude the arteries and cause ischemia.
Choice B reason: Decreases highly sensitive C-reactive protein (hsCRP) levels is not a role of inflammation in the development of atherosclerosis, but an indicator of it. hsCRP is a marker of systemic inflammation that is produced by the liver in response to cytokines. It is elevated in patients with atherosclerosis and correlates with the risk of cardiovascular events.
Choice C reason: Damages the endothelium of the arteries is the main role of inflammation in the development of atherosclerosis. Endothelial injury exposes the subendothelial layer to the blood, which triggers the adhesion of monocytes and platelets. Monocytes differentiate into macrophages and engulf oxidized low-density lipoproteins (LDL), forming foam cells. Foam cells accumulate in the intima and form fatty streaks, which are the earliest lesions of atherosclerosis.
Choice D reason: Causes diffuse arterial vasoconstriction is not a role of inflammation in the development of atherosclerosis, but a consequence of it. Atherosclerosis narrows the lumen of the arteries and reduces the blood flow to the tissues. This causes ischemia, which stimulates the release of vasoconstrictors such as angiotensin II and endothelin. Vasoconstriction further worsens the ischemia and increases the blood pressure.
Correct Answer is B
Explanation
Choice A reason: Prostaglandins are inflammatory mediators that are derived from arachidonic acid. They are involved in both the early and late phases of type 1 hypersensitivity response, but they do not cause immediate bronchoconstriction and vasodilation. They mainly cause pain, fever, and inflammation.
Choice B reason: Histamine is an inflammatory mediator that is stored in mast cells and basophils. It is released during the early phase of type 1 hypersensitivity response, which occurs within minutes of exposure to an allergen. It causes immediate bronchoconstriction and vasodilation, as well as increased vascular permeability, mucus secretion, and itching.
Choice C reason: Leukotrienes are inflammatory mediators that are derived from arachidonic acid. They are involved in the late phase of type 1 hypersensitivity response, which occurs several hours after exposure to an allergen. They cause sustained bronchoconstriction and inflammation, as well as increased mucus production and airway edema.
Choice D reason: Bradykinin is an inflammatory mediator that is formed from plasma proteins. It is not directly involved in type 1 hypersensitivity response, but it may be activated by the complement system, which is part of the innate immune system. It causes vasodilation, increased vascular permeability, and pain.
