A nurse is teaching a client scheduled for an activated partial thromboplastin time (aPTT). Which of the following statements by the client indicates an understanding of the teaching?

"This test will help my provider adjust my warfarin dosages."

"If my levels are too low, I am at an increased risk for bleeding."

"It measures deficiencies in clotting factors."

"I will need to skip breakfast until after the test is complete

Answer and Explanation

The Correct Answer is C

A. "This test will help my provider adjust my warfarin dosages": aPTT is not typically used to monitor warfarin therapy. Instead, it is more commonly associated with monitoring heparin therapy.

B. "If my levels are too low, I am at an increased risk for bleeding": This statement is inaccurate. Low levels of clotting factors could lead to a prolonged aPTT, which might increase the risk of bleeding.

C. "It measures deficiencies in clotting factors."

Activated partial thromboplastin time (aPTT) is a laboratory test that evaluates the intrinsic pathway of the coagulation cascade. The aPTT measures the time it takes for a clot to form and reflects the activity of various clotting factors, including factors VIII, IX, XI, and XII. An elevated aPTT may indicate a deficiency or dysfunction of one or more clotting factors.

D. "I will need to skip breakfast until after the test is complete": There is no need for the client to skip breakfast before an aPTT test. The test is not affected by food intake.

Correct Answer is C

Explanation

A. Hypertension: Anemia is more likely to be associated with hypotension rather than hypertension. The body often responds to anemia by increasing heart rate and cardiac output to compensate for reduced oxygen-carrying capacity.

B. Diarrhea: Anemia itself is not directly associated with diarrhea. Excess blood loss can lead to anemia, but diarrhea is not a typical manifestation of anemia.

C. Fatigue: This is the correct answer. Fatigue is a common symptom of anemia, as reduced oxygen delivery to tissues can lead to feelings of weakness, tiredness, and lack of energy.

D. Bradycardia: Anemia is more likely to be associated with compensatory tachycardia (increased heart rate) rather than bradycardia. The body attempts to maintain oxygen delivery to tissues by increasing cardiac output.

A. Metabolic acidosis B. Metabolic alkalosis C. Respiratory acidosis D. Respiratory alkalosis

Correct Answer is C

Explanation

pH 7.22: Indicates acidosis (normal range: 7.35-7.45).

PaCO2 68 mm Hg: Elevated partial pressure of carbon dioxide, suggesting respiratory acidosis (normal range: 35-45 mm Hg).

Base excess -2: Indicates a mild metabolic acidosis.

PaO2 78 mm Hg: Within the normal range (80-100 mm Hg), indicating adequate oxygenation.

Saturation 80%: Below the normal range (95-100%), suggesting some degree of hypoxemia.

Bicarbonate 26 mEq/L: Elevated bicarbonate levels, suggesting metabolic compensation for the respiratory acidosis.

Therefore, the client is experiencing respiratory acidosis with partial metabolic compensation (mild metabolic acidosis).
