A nurse is managing the care of a client who is postoperative and has acute adrenal insufficiency. Which of the following actions should the nurse take? (A) Administer IV hydrocortisone sodium. (B) Give oral spironolactone. (C) Infuse 1 unit of platelets. (D) Restrict daily fluid intake.

Administer IV hydrocortisone sodium [Hydrocortisone sodium is necessary to replace the cortisol deficiency that occurs with adrenal insufficiency] (Administering a potassium-sparing diuretic, such as spironolactone, will further increase the client's potassium level, worsening the hyperkalemia) (infusing platelets is not appropriate for a client who has acute adrenal insufficiency) (Acute adrenal insufficiency causes hypovolemia, which is an indication for rapid fluid replacement)

A nurse is teaching a client who has an autoimmune disease about the adverse effects of long-term corticosteroid therapy. Which of the following adverse effects should the nurse include? (Select all that apply.) [ ]Osteoporosis [ ] Moon-shaped face [ ] Increased risk of infection [ ] Hearing loss [ ] Weight loss

[ ] Osteoporosis [ ] Moon-shaped face [ ] Increased risk of infection (Long-term corticosteroid therapy can cause cataracts and glaucoma, but it does not cause hearing loss) (Long-term corticosteroid therapy is more likely to cause weight gain due to fluid and sodium retention)

(A) "Drink at least 3 liters of fluid per day." (B) "Weigh yourself weekly while wearing similar clothing at the same time of day." (C) "Notify the provider of a weight loss of 1 pound or more per week." (D) "Report nocturia because it requires a dosage adjustment."

"Report nocturia because it requires a dosage adjustment." [The client should take the initial dose of desmopressin in the evening. The provider will increase the dosage until the client no longer has nocturia] (A weight gain or loss of 0.45 kg (1 lb) per week is not enough to suggest overhydration or dehydration) (The client should weigh himself daily to detect dehydration in its early stage) (The client should drink an amount of fluid equal to his urine output each day)

A nurse is teaching a client who is scheduled for a vanillylmandelic acid test to screen for pheochromocytoma. Which of the following statements should the nurse include in the teaching? (A) "Start fasting at midnight prior to the day of the test." (B)"Begin the 24-hour urine collection with the first morning urination." (C) "Take low-dose aspirin for pain during the testing period." (D) "Restrict coffee intake 2 to 3 days prior to the test."

"Restrict coffee intake 2 to 3 days prior to the test." [The client should avoid coffee and tea, even if they are decaffeinated, bananas, chocolate, and vanilla for 2 to 3 days prior to the test] (The client does not have to fast prior to the test, but there are foods the client should avoid, such as bananas and citrus fruits) (The client should discard the first morning urine, and then collect all urine after that for 24 hr) (The client should avoid aspirin because it can affect test results)

A nurse is developing a teaching plan for a client who had a thyroidectomy and takes a thyroid hormone replacement. Which of the following instructions should the nurse plan to include? (A) "Take this medication on an empty stomach." (B) (C) (D)

"Take this medication on an empty stomach." [To promote proper absorption, the client should take the medication on an empty stomach and not eat or drink anything for 30 to 60 min after] (Aluminum-containing antacids and calcium supplements can reduce the effectiveness of thyroid replacement therapy) (This medication can increase blood glucose levels in clients who have diabetes mellitus. However, it does not cause orthostatic hypotension) (Since there are no fluid restrictions with this medication therapy, the client should drink 2 to 3 L of fluid daily)

A nurse is teaching a client about glycosylated hemoglobin (HbA1c) testing. Which of the following client statements indicates an understanding of the teaching? (A) "I need to fast after midnight the night before the test." (B) "This test's result is a good indicator of my average blood glucose levels." (C) "A level of 8 to 10 percent suggests adequate blood glucose control." (D) "I will use my hemoglobin A1c level to adjust my daily insulin doses."

"This test's result is a good indicator of my average blood glucose levels." [HbA1c reflects the client's glucose levels over a 120-day period, which is the life span of RBCs] (The client does not need to fast before blood sampling for HbA1c. What the client eats the day before has no effect on the results of this test.) (The expected reference range for HbA1c is 4-6% for adults. A result greater than 6.5% can indicate diabetes) (The client should use capillary blood glucose levels to adjust daily insulin doses with the provider's approval)

Diabetes insipidus diagnostic tests:

(1) A 24-hr measurement of I&O (2) urine specific gravity (3) urine osmolarity

What exceeding level of blood glucose should the patient call the provider and when should the client check their urine for ketones?

(1) Call HCP if blood glucose levels exceed 25 mg/dL (2) Check for ketones when blood glucose levels exceed 240 mg/dL

Elevate the head of the client's bed. [The nurse should elevate the head of the client's bed to reduce blood pressure and abdominal pressure] (The nurse should not palpate the abdomen of a client who has a pheochromocytoma, because this can cause release of catecholamines and increase blood pressure) (The nurse should monitor a client who has a pheochromocytoma for hypertension) (The nurse should monitor the urine specific gravity of a client who has diabetes insipidus)

A nurse is monitoring the laboratory values of a client who has diabetes mellitus and is taking insulin. Which of the following results indicates a therapeutic outcome of insulin therapy?

Hirsutism [Increased hair growth, or hirsutism, is an expected finding of Cushing's disease due to increased androgen production] (Thinning of the skin is an expected finding of Cushing's disease)

A nurse is assessing a client who is taking propylthiouracil. The nurse should identify which of the following findings as an indication that the medication has been effective? (A) Increased ability to sweat (B) Increased bowel movements (C) Increased body weight (D) Increased libido

Increased body weight [Propylthiouracil suppresses the production of thyroid hormones and allows for weight gain. However, excessive weight gain could indicate that the dose of propylthiouracil is too high] (Propylthiouracil is an antithyroid agent that is expected to decrease diaphoresis) (Increased bowel movements is a manifestation of hyperthyroidism. Propylthiouracil is an antithyroid agent that is expected to decrease bowel movements) (Increased libido is a manifestation of hyperthyroidism. Propylthiouracil is an antithyroid agent that is expected to decrease libido)

Glucose levels will be above 600 mg/dL] (This laboratory value indicates the client has diabetic ketoacidosis. Clients who are experiencing HHS will have a pH greater than 7.40) (This laboratory value indicates the client has hyperglycemia. Clients who are experiencing HHS will have a blood glucose level greater than 600 mg/dL) (This laboratory value indicates the client has hyperglycemia. Clients who are experiencing HHS will have a blood glucose level greater than 600 mg/dL)
