Question 1 of 5
A nurse is assessing a client who has restrictive cardiomyopathy (RCM). Which of the following statements should the nurse cue in the client?
Correct Answer: D
Rationale: Restrictive cardiomyopathy involves fibrous and fatty ventricular tissue, causing stiffness that impairs diastolic filling.
Question 2 of 5
A nurse is reviewing laboratory results and notes that a client has an elevated thyroid-stimulating hormone (TSH) level. Which of the following assessment findings would the nurse expect?
Correct Answer: B
Rationale: Elevated TSH indicates hypothyroidism, which slows metabolism, leading to fatigue, constipation, and weight gain.
Question 3 of 5
A nurse is caring for a client who reports increased anxiety, nervousness, heat intolerance, and unintentional weight loss. Blood testing reveals decreased thyroid-stimulating hormone (TSH), elevated thyroxine (T4), and elevated triiodothyronine (T3). Which of the following vital sign abnormalities does the nurse anticipate?
Correct Answer: B
Rationale: Hyperthyroidism, indicated by low TSH and high T4/T3, increases metabolism, causing tachycardia.
Question 4 of 5
A nurse is caring for a client who has diabetic ketoacidosis (DKA) and is manifesting Kussmaul breathing. Which of the following pathophysiological mechanisms is related to Kussmaul breathing?
Correct Answer: B
Rationale: Kussmaul breathing is a compensatory mechanism for metabolic acidosis in DKA, where rapid, deep breathing helps expel carbon dioxide to reduce blood acidity.
Question 5 of 5
The nurse is providing care for a client who has syndrome of inappropriate antidiuretic hormone (SIADH) and is critically ill. Which of the following lab findings requires immediate intervention?
Correct Answer: C
Rationale: A serum sodium level of 125 mEq/L indicates severe hyponatremia in SIADH, requiring immediate intervention to prevent neurological complications.
