A client's morning laboratory test results include hemoglobin 11.0 g/dL (110 g/L) and hematocrit 34% (0.34 volume fraction). Based on these findings, this client is at risk for which pathophysiological findings?

Reference Ranges:

Hemoglobin [14 to 18 g/dL (140 to 180 g/L)]

Hematocrit [42% to 52% (0.42 to 0.52 volume fraction)]

Fatigue and weakness.

Cardiac dysrhythmias.

Fever and infection.

Decreased clotting time.

Answer and Explanation

The Correct Answer is A

A) Fatigue and weakness:

Correct. The client's hemoglobin and hematocrit levels are below the reference ranges, indicating mild anemia. Anemia, characterized by low red blood cell count or hemoglobin levels, can lead to symptoms such as fatigue, weakness, and shortness of breath, as the body's oxygen-carrying capacity is reduced. Fatigue and weakness are common manifestations of anemia and are indicative of tissue hypoxia due to decreased oxygen delivery.

B) Cardiac dysrhythmias:

While severe anemia can lead to cardiac complications, such as dysrhythmias, the client's hemoglobin and hematocrit levels are only slightly below the reference ranges, indicating mild anemia. Cardiac dysrhythmias are more commonly associated with severe anemia or acute changes in hemoglobin levels rather than the mild anemia indicated in this scenario.

C) Fever and infection:

Anemia is not typically associated with fever and infection. While anemia may occur secondary to chronic inflammatory conditions or certain infections, the client's symptoms of fatigue and weakness are more directly related to the decreased oxygen-carrying capacity of the blood due to mild anemia.

D) Decreased clotting time:

Anemia is not directly associated with changes in clotting time. While severe anemia can lead to alterations in platelet function and clotting factors, the client's hemoglobin and hematocrit levels are only slightly below the reference ranges, indicating mild anemia. Decreased clotting time is not a typical manifestation of mild anemia.

Correct Answer is C

Explanation

Acne vulgaris is a common skin condition characterized by various types of lesions, including comedones, papules, and pustules, primarily affecting areas with a high density of sebaceous glands, such as the face, neck, chest, and upper back. Here's why option C is the correct choice:

A) Small, skin-colored, pedunculated papules in areas of skin folds and on other areas as skin tags:

This description is more characteristic of acrochordons or skin tags, which are benign skin growths commonly found in areas of friction or skin folds. Skin tags are not typically associated with acne vulgaris.

B) Hyperpigmented areas that vary in form and color and are slightly elevated from the skin:

This description suggests post-inflammatory hyperpigmentation, which can occur after resolution of inflammatory lesions in acne vulgaris. However, it does not capture the primary pathological findings observed in active acne lesions.

C) Hyperactive sebaceous areas forming comedones, papules, pustules on the face, neck, and upper back:

Correct. Acne vulgaris is characterized by the formation of various lesions, including comedones (open and closed), papules, and pustules, resulting from the obstruction of hair follicles and overactivity of sebaceous glands. These lesions typically appear on areas with a high density of sebaceous glands, such as the face, neck, chest, and upper back.

D) Sharply demarcated silvery scaling plaques with underlying redness on the elbows and knees:

This description is more indicative of psoriasis, a chronic autoimmune skin condition characterized by sharply demarcated, raised, silvery scaling plaques commonly affecting extensor surfaces such as the elbows and knees. Psoriasis lesions are distinct from those seen in acne vulgaris.

A. Elevation in blood pressure. B. Vasospasm at insertion site. C. Clot in the arterial catheter. D. Air lock in the transducer.

Correct Answer is B

Explanation

A) Elevation in blood pressure:

While elevation in blood pressure could potentially cause discomfort at the arterial line insertion site, it is not the most likely physiological effect to induce sudden pain in this scenario. Blood pressure elevation would typically cause generalized symptoms rather than localized pain at the insertion site.

B) Vasospasm at insertion site:

Correct. Vasospasm refers to the sudden constriction of blood vessels, leading to reduced blood flow. It can occur in response to arterial puncture or manipulation during arterial line insertion, resulting in sudden pain at the insertion site.

C) Clot in the arterial catheter:

A clot in the arterial catheter could potentially cause obstruction and affect blood flow, but it is less likely to induce sudden pain at the insertion site unless there is associated ischemia or tissue damage.

D) Air lock in the transducer:

An air lock in the transducer could disrupt pressure monitoring but is not typically associated with sudden pain at the insertion site. It may lead to inaccurate pressure readings rather than localized pain.
