A nurse is preparing to administer a client’s daily dose of NPH insulin at 0730. The nurse should expect this type of insulin to peak within which of the following timeframes after administration? A. 30 min to 3 hr Rationale: Rapid-acting insulin peaks in 30 min to 3 hr. NPH insulin is not a rapid-acting insulin. B. 1 to 5 hr Rationale: Short-acting insulin peaks in 1 to 5 hr. NPH insulin is not short acting insulin. C. 4 to 14 hr Rationale: NPH insulin, an intermediate-acting insulin, peaks at 4 to 14 hr following administration. D. 2 to 6 hr Rationale: Long-acting insulin does not have a discernible peak level. NPH insulin is not long-acting insulin. 2. A nurse is caring for a client who has Cushing's syndrome. Which of the following clinical manifestations should the nurse expect to observe? (Select all that apply.) A. Buffalo hump B. Purple striations C. Moon face D. Tremors E. Obese extremities Rationale: Buffalo hump is correct. Cushing's syndrome is a disease caused by an increased production of cortisol or by excessive use of corticosteroids. Buffalo hump, a collection of fat between the shoulders, is a common manifestation of Cushing's syndrome. Purple striations is correct. Purple striations on the skin of the abdomen, thighs, and breasts are a common manifestation of Cushing's syndrome. This is due to the collection of body fat in these areas. Moon face is correct. Moon face is a common manifestation of Cushing's syndrome. Clients who have this manifestation present with a round, red, full face. Tremors is incorrect. Tremors are not a common finding of Cushing's syndrome. Obese extremities is incorrect. Clients who have Cushing's syndrome have truncal obesity, a protuberant abdomen, with thin extremities, which is due to an alteration in protein metabolism. 3.

At which of the following times should the nurse observe for hypoglycemia caused by the onset of the medication? A. 0715 Rationale: Insulin lispro, a rapid-acting insulin, has an expected onset of 15 min. NPH insulin is not a rapid-acting insulin; therefore, the nurse should not observe for hypoglycemia caused by the onset of the medication beginning at 0715. B. 0730 Rationale: Regular insulin, a short-acting insulin, has an expected onset of 30 to 60 min. NPH insulin is not a short-acting insulin; therefore, the nurse should not observe for hypoglycemia caused by the onset of the medication beginning at 0730. C. 0900 Rationale: NPH insulin is an intermediate-acting insulin, and has an expected onset of 1½ to 4 hr with a peak of 4 to 12 hours. Therefore, the nurse should observe for hypoglycemia caused by the onset of the medication beginning at 0900. D. 1200 Rationale: NPH insulin is an intermediate-acting insulin, and has an expected onset of 1½ to 4 hr. Therefore, the nurse should observe for hypoglycemia caused by the onset of the medication before 1200. 5. A nurse is reviewing a client's admission laboratory findings that indicate the client has hyponatremia. Which of the following laboratory findings should the nurse also expect to be below the expected reference range? A. Magnesium Rationale: Hyponatremia refers to a decrease in the sodium level.

Created on:12/14/2022 Page 3 Downloaded by El Poe Musical TV (elpoemusicaltv@gmail.com) lOMoARcPSD|24092885 Detailed Answer Key Term 3 - Endocrine_2022 C. Chloride Rationale: Hyponatremia refers to a decrease in the sodium level. The loss of sodium, a positively-charged ion, results in the loss of chloride, a negatively-charged ion, because these electrolytes have an electrical attraction to each other. D. Potassium Rationale: Hyponatremia refers to a decrease in the sodium level. The loss of sodium does not result in the loss of potassium. 6. A nurse is reinforcing teaching with a client who has diabetes mellitus and self-administers insulin. The client reports drinking an occasional glass of wine. Which of the following is an appropriate response by the nurse? A. “Wine is loaded with carbohydrates, so you should try to avoid it.” Rationale: Wine contains carbohydrates in varying amounts and may raise the client’s blood glucose level or place the client at risk of nighttime hypoglycemia. Limiting the number of drinks per day can prevent diabetic complications. B. “You may have no more than three drinks a day.” Rationale: The client who has diabetes mellitus may drink alcohol in moderation. For women, that means one drink or less per day and for men, two drinks or less per day because of the high carbohydrate content. C. “Drinking plenty of water with your wine will lessen its effects.” Rationale: Water will not reduce the client’s risk of hypoglycemia when drinking alcohol. Alcohol beverages are high in carbohydrates even when diluted. D. “It is best for you to drink an occasional glass of wine with a meal.” Rationale: Ingesting alcohol with a meal helps reduce the risk of nighttime hypoglycemia for clients who receive insulin therapy. 7. A nurse in a provider's office is collecting data from a client who has hypothyroidism. Which of the findings should the nurse expect? A. Blurred vision Rationale: Blurred vision is an expected finding for a client who has hyperthyroidism, not hypothyroidism. B. Moist skin Rationale: Moist skin is an expected finding for a client who has hyperthyroidism, not hypothyroidism. C. Bradycardia Rationale: Reduced thyroid hormone levels (hypothyroidism) reduce the body's metabolic rate and thus slow down various body functions. Bradycardia reflects slowed cardiovascular function.

Diaphoresis Rationale: The nurse should monitor for this finding in a client who has hypermagnesemia. 13. A nurse is reviewing a client’s medical record. Which of the following laboratory tests should the nurse examine to determine risk factors for metabolic syndrome? A. Liver function studies and bilirubin Rationale: The nurse can review the client’s HDL cholesterol level, since a finding less than 40 mg/dl for male clients or less than 50 mg/dL for female clients is a risk factor for metabolic syndrome. B. Fasting glucose and triglycerides Rationale: The nurse should review the client’s findings for a fasting glucose equal to or above 100 mg/dL, a triglyceride level greater than 150 mg/dL, or taking medicine to treat either condition are risk factors for metabolic syndrome. The nurse should also examine the client’s waist circumference, HDL cholesterol level, and blood pressure readings. C. CBC and BUN Rationale: The nurse should review the client’s blood pressure, since a blood pressure at or above 130/85 mm Hg, or taking treatment for hypertension, are risk factors for metabolic syndrome. D. Basic metabolic profile and troponin I Rationale: The nurse can measure the client’s waist circumference, since a measurement greater than 102 cm (40 in) for men or 88 cm (35 in) for women is a risk factor for metabolic syndrome. 14.

A nurse is caring for a client who is prescribed 15 units of NPH insulin to be administered at 0700. At which of the following times of day is most appropriate for the nurse plan to offer a snack? A. 0730 Rationale: The client is at risk for hypoglycemia due to taking insulin. However, since the onset of action for NPH insulin is 1 to 2 hr after administration, there is another time that is more appropriate for the nurse to offer a snack. Clients taking rapid acting insulin, such as insulin lispro, can require food just before or immediately after insulin administration. B. 0900 Rationale: The client is at risk for hypoglycemia due to taking insulin. However, since the onset of action for NPH insulin is 1 to 2 hr after administration and the 0900 time frame falls just after breakfast, there is another time is more appropriate for the nurse to plan to offer a snack. Clients taking regular insulin are at high risk for hypoglycemia 2 hr after administration. Created on:12/14/2022 Page 8 Downloaded by El Poe Musical TV (elpoemusicaltv@gmail.com) lOMoARcPSD|24092885 Detailed Answer Key Term 3 - Endocrine_2022 C. 1230 Rationale: The client is at risk for hypoglycemia due to taking insulin. However, since the peak action for NPH insulin begins 4 to 6 hr after administrations and the 1230 time frame falls just after lunch, there is another time is more appropriate for the nurse to plan to offer a snack. D. 1500 Rationale: Taking NPH insulin indicates that this client is at greatest risk for hypoglycemia about 8 hr after administration, in the middle of the peak action time. The nurse should plan to offer the client a snack during the middle of the afternoon between lunch and dinner to maintain the client’s blood glucose level. 17. A nurse is assisting with the care of a client who 1 day postoperative following a thyroidectomy and reports severe muscle spasms of the lower extremities. Which of the following actions should the nurse take? A. Monitor the client's peripheral pulses. Rationale: This client is experiencing hypocalcemia following a thyroidectomy, so there is no indication the peripheral pulses are diminished. Therefore, there is no need for the nurse to monitor them at this time. B. Determine the client's calcium level. Rationale: The nurse should determine the client's calcium level. A client who has had a thyroidectomy is at risk of hypocalcemia due to possible disruption of the parathyroid gland during surgery. The parathyroid glands are four small glands located inside the thyroid gland. They are responsible for calcium regulation and, if they are damaged during a thyroidectomy, there is a risk of hypocalcemia. Low calcium levels can be manifested as numbness and tingling of the fingers and around the mouth, muscle spasms (particularly of the hands and feet), and hyperactive reflexes. If a client develops any of these symptoms following a thyroidectomy, it would be important to see what the latest calcium level is. C. Administer intravenous normal saline solution. Rationale: In acute hypercalcemia, rather than hypocalcemia, normal saline solution is administered to dilute plasma calcium. In this client, administering fluids to dilute calcium would increase the muscle spasms and cause the client's condition to deteriorate. D. Give the client an oral potassium supplement. Rationale: Giving the client an oral potassium supplement is indicated for hypokalemia, rather than hypocalcemia. An oral potassium supplement would not improve this client's condition. 18. A nurse is caring for a client who has type 1 diabetes mellitus and observes mild hand tremors. Which of the following snacks should the nurse offer the client after obtaining a glucometer reading of 60 mg/dL? A. 4 oz of regular soda Rationale: The nurse should plant to administer 15 to 20 g of fast-acting carbohydrates to treat the client’s blood glucose. A half-cup of fruit juice or soda is appropriate treatment.

D. 6 oz of milk Rationale: The nurse should provide the client with 8 oz of milk to provide the appropriate amount of carbohydrates. 19. A nurse is reinforcing discharge teaching about self-administered peritoneal dialysis with a client. Which of the following statements by the client indicates an understanding of the teaching? A. "The fluid from my abdomen will be slightly cloudy." Rationale: Fluid that is discolored, cloudy, or has an odor can indicate the presence of an infection. The client should expect the dialysate output to be clear. B. "The catheter can be handled using clean precautions." Rationale: The client should use aseptic technique when handling the catheter and equipment to prevent infection of the peritoneal cavity. C. "I should use the microwave in my kitchen to warm the solution before using it." Rationale: The client should use a dialysate warmer to warm the solution prior to use. D. "The amount of the liquid output should be greater than what was put in." Rationale: Dialysis is used to remove excess fluid and waste from the body. If less fluid is drained than was initially instilled, the nurse should have the client change positions to allow the fluid to shift in the abdomen so that the catheter can remove it. 20. A nurse is monitoring a client who received desmopressin (DDAVP) to treat diabetes insipidus. Which of the following findings indicates effectiveness of the medication? A. Serum sodium 150 mEq/L Rationale: The nurse should recognize that diabetes insipidus causes hypernatremia. This finding is above the expected reference range; therefore, this finding does not indicate effective treatment. B. Decreased blood pressure Rationale: The nurse should recognize that diabetes insipidus causes hypotension; therefore, this finding does not indicate effective treatment. Created on:12/14/2022 Page 10 Downloaded by El Poe Musical TV (elpoemusicaltv@gmail.com) lOMoARcPSD|24092885 Detailed Answer Key Term 3 - Endocrine_2022 C. Urine specific gravity 1.015 Rationale: Diabetes insipidus occurs when the posterior pituitary gland does not secrete enough antidiuretic hormone causing excessive, diluted urine. Desmopressin provides replacement posterior pituitary hormone; therefore, the nurse should identify a urine specific gravity level within the expected reference range indicates effectiveness of the medication. D. Increased heart rate Rationale: The nurse should recognize that diabetes insipidus causes tachycardia; therefore, this finding does not indicate effective treatment. 21. A nurse is collecting data from a client who has been taking methimazole for hyperthyroidism. For which of the following findings should the nurse monitor to identify that the medication is effective? A. Weight loss Rationale: A client who has hyperthyroidism has an increased metabolism and is at risk for weight loss. B.

When obtaining a medical history, the nurse should ask for additional information about which of the following conditions? (Select all that apply.) A. Osteoarthritis B. Lung cancer C. Liver cirrhosis D. Dyspepsia E. Seizures Rationale: Osteoarthritis is incorrect. It is not necessary for the nurse to ask about osteoarthritis when obtaining a medical history because it does not impact the secretion of antidiuretic hormone. Lung cancer is correct. The nurse should ask the client about lung cancer when obtaining a medical history because some of the treatment options for small cell lung cancer can cause secretion of antidiuretic hormone. This results in the body retaining water and can cause SIADH.Liver cirrhosis is incorrect. It is not necessary for the nurse to ask about liver cirrhosis when obtaining a medical history because it does not impact the secretion of antidiuretic hormone.Dyspepsia is incorrect. It is not necessary for the nurse to ask about dyspepsia when obtaining a medical history because it does not impact the secretion of antidiuretic hormone.Seizures is correct. The nurse should ask the client about seizures when obtaining a medical history. Due to increase fluid volume, the excess results in hyponatremia which can cause confusion. 27.

Rationale: The greatest risk to the client is the development of diabetic ketoacidosis, which results from an absence of insulin and manifests as elevated blood glucose levels. Therefore, the most important action for the client to take is to monitor the blood glucose level frequently. C. "Drink 8 ounces of fluid every hour while awake." Rationale: The nurse should include the importance of fluid intake to prevent dehydration in the client who is ill; however, another action is the priority. D. "Take the usual dosage of insulin." Rationale: The nurse should emphasize the importance of continued insulin use, even in the event of illness, as the client who has diabetes mellitus type 1 is unable to manufacture insulin. Failure to take insulin results in the body metabolizing fat to meet metabolic needs. This causes an increase in circulating ketones and predisposes the client to the development of diabetic ketoacidosis. Another action, however, is the priority. 57.
