A nurse is preparing to collect a specimen from a client for a guaiac test. The client asks what the test will detect in his stool. Which of the following responses should the nurse make?

a. Neck vein distention: Neck vein distention may indicate fluid overload, but it is not a direct measure of fluid losses.

b. Body weight: Monitoring body weight before and after hemodialysis provides a direct

measure of fluid losses. Hemodialysis removes excess fluid, and changes in body weight reflect fluid balance.

c. Abdominal girth: Abdominal girth may be affected by fluid accumulation but is not a direct measure of fluid losses during hemodialysis.

d. Blood pressure: While blood pressure may be influenced by fluid status, it is not a specific measure of fluid losses during hemodialysis. Body weight is a more direct indicator of fluid removal.

a. Nausea: Nausea is a common symptom of myocardial infarction and can be associated with autonomic nervous system activation.

b. Orthopnea: Orthopnea, difficulty breathing while lying down, is more commonly associated with heart failure, not necessarily myocardial infarction.

c. Diaphoresis: Profuse sweating or diaphoresis is a common manifestation of myocardial infarction due to sympathetic nervous system activation.

d. Headache: Headache is not a typical symptom of myocardial infarction. However, some individuals may experience atypical symptoms.

e. Tachycardia: Tachycardia (rapid heart rate) is a common response to myocardial infarction and can be associated with sympathetic nervous system stimulation in response to decreased cardiac output.
