A nurse in a provider's office is assessing a client who reports occasional atypical chest pain, palpitations, and exercise intolerance. On auscultation, the nurse notes a systolic click. The nurse should recognize this finding as a manifestation of which of the following conditions?

Aortic regurgitation,

Mitral stenosis

Aortic stenosis

Mitral valve prolapse

Answer and Explanation

The Correct Answer is D

A. Aortic regurgitation: Aortic regurgitation typically presents with a diastolic murmur, not a systolic click.

B. Mitral stenosis: Mitral stenosis presents with a diastolic murmur, often associated with an opening snap, rather than a systolic click.

C. Aortic stenosis: Aortic stenosis typically presents with a systolic ejection murmur, but not a systolic click.

D. Mitral valve prolapse: This is the correct answer. Mitral valve prolapse (MVP) is characterized by the displacement of the mitral valve leaflets into the left atrium during systole, often producing a systolic click. Symptoms associated with MVP can include atypical chest pain, palpitations, and exercise intolerance.

Correct Answer is C

Explanation

A. Bradypnea: Bradypnea refers to abnormally slow breathing. In the context of postoperative atelectasis and hypoxia, the client is more likely to exhibit tachypnea (rapid breathing) as the body attempts to compensate for reduced oxygen levels.

B. Bradycardia: Bradycardia is an abnormally slow heart rate. While hypoxia can lead to changes in heart rate, it is more common to observe tachycardia (increased heart rate) as a compensatory response to decreased oxygen levels.

C. Intercostal retractions: Intercostal retractions occur when the muscles between the ribs pull inward during inspiration. In a client with atelectasis and hypoxia, increased respiratory effort may result in intercostal retractions as the body tries to enhance airflow and improve oxygenation.

D. Lethargy: Lethargy refers to a state of drowsiness or fatigue. While hypoxia can lead to lethargy, it is not a specific respiratory manifestation. Other respiratory signs, such as increased respiratory rate and retractions, are more likely to be observed.

A. "This test will help my provider adjust my warfarin dosages." B. "If my levels are too low, I am at an increased risk for bleeding." C. "It measures deficiencies in clotting factors." D. "I will need to skip breakfast until after the test is complete

Correct Answer is C

Explanation

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.
