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 D

Explanation

A. Dependent edema: Dependent edema is more commonly associated with right-sided heart failure. In left-sided heart failure, fluid accumulates in the lungs, leading to pulmonary symptoms such as cough and frothy sputum.
B. Jugular distention: Jugular distention is often associated with right-sided heart failure due to impaired blood flow from the right atrium into the right ventricle. It is less likely to be prominent in left-sided heart failure.
C. Nocturnal polyuria: Nocturnal polyuria (increased urination at night) is a common symptom of heart failure, but it is not specific to left-sided heart failure. It can be seen in both left- and right-sided heart failure.
D. Frothy sputum: This is the correct answer. Left-sided heart failure can lead to pulmonary congestion, resulting in the accumulation of fluid in the lungs. Frothy, pink-tinged sputum is a characteristic finding in left-sided heart failure and is often associated with pulmonary edema.

A. A room that is within view of the nurses' station B. A room in the ICU C. A room with another nonsurgical client D. A room with air exhaust directly to the outdoor environment

Correct Answer is D

Explanation

A. A room that is within view of the nurses' station: While visibility to the nurses' station is advantageous for monitoring the client, it is not the most critical consideration for a client with active tuberculosis. The priority is to prevent the spread of infectious droplets to other clients and healthcare workers.

B. A room in the ICU: Placing a client with active tuberculosis in the ICU may not be necessary unless there are specific medical reasons requiring intensive care. However, the room assignment should prioritize infection control measures.

C. A room with another nonsurgical client: It is not advisable to place a client with active tuberculosis in a room with another nonsurgical client due to the risk of spreading the infection to a potentially vulnerable individual.

D. A room with air exhaust directly to the outdoor environment: This is the correct answer. The preferred room assignment for a client with active tuberculosis is one with proper ventilation that allows air to be exhausted directly to the outdoor environment. Negative pressure rooms with high-efficiency particulate air (HEPA) filtration are often used to minimize the risk of airborne transmission.
