Question 1 of 5
A client who has hypothyroidism will be undergoing surgery for a total knee replacement. When planning care for this client, the nurse understands which of the following to be true for people who have hypothyroidism?
Correct Answer: D
Rationale: Hypothyroidism reduces metabolism, increasing opioid sensitivity, requiring lower doses (
D). Hyperthermia (
A) is incorrect; hypothermia is more likely. Levothyroxine (
B) shouldn't be held without guidance. Tachycardia (
C) is associated with hyperthyroidism.
Question 2 of 5
A client is experiencing tachycardia and tremors. Lab values show elevated Free T4 and low thyroid stimulating hormone (TSH). Which diagnostic study will help the practitioner differentiate Graves' disease from other forms of hyperthyroidism?
Correct Answer: B
Rationale: RAIU test (
B) differentiates Graves' disease (high uptake) from other hyperthyroidism causes. Levothyroxine test (
A) is irrelevant. ACTH test (
C) assesses adrenal function. Thyroidectomy (
D) is a treatment, not a diagnostic test.
Question 3 of 5
A client seen in the clinic with shortness of breath and fatigue is being evaluated for a possible diagnosis of heart failure. Which laboratory result will be the most useful for diagnosing heart failure?
Correct Answer: A
Rationale: BNP (
A) is the most specific marker for heart failure, elevated due to cardiac pressure and volume overload. Troponin I (
B) indicates myocardial infarction. BUN (
C) may be elevated in heart failure but is less specific. Platelet levels (
D) are unrelated to heart failure diagnosis.
Question 4 of 5
A nurse is caring for a client who has hypokalemia, hyperglycemia, and hypertension. A diagnosis of Cushing syndrome is suspected.Which of the following tests would the nurse anticipate the health care provider will order to help confirm the diagnosis of Cushing syndrome?
Correct Answer: B
Rationale: The 24-hour cortisol urine study (
B) measures cortisol levels to confirm Cushing syndrome, characterized by excess cortisol. Radioactive iodine uptake (
A) is for thyroid disorders. ACTH stimulation test (
C) assesses adrenal insufficiency, not Cushing syndrome. Edrophonium test (
D) diagnoses myasthenia gravis, unrelated to Cushing syndrome.
Question 5 of 5
A client complaining of weight gain and acne undergoes laboratory testing, which reveals elevated cortisol levels and hyperglycemia. The client has no prior medical history, and does not take any medications. After further testing and imaging to determine the cause of the elevated cortisol levels, the client is diagnosed with Cushing disease caused by a pituitary adenoma. Which of the following statements should the nurse include when teaching the client about this diagnosis?
Correct Answer: B
Rationale: Cushing disease from a pituitary adenoma requires surgical removal of the pituitary tumor, not adrenal glands (
B). Tapering corticosteroids (
A) is irrelevant as the client isn't taking them. Hydrocortisone (
C) is for Addison's disease. Glucose checks (
D) are secondary to addressing the tumor.
