Nursing Elites

1. In a male client with a history of hypertension diagnosed with primary hyperaldosteronism, the hypertension is caused by excessive hormone secretion from which of the following glands?

• A. Adrenal cortex
• B. Pancreas
• C. Adrenal medulla
• D. Parathyroid

Correct answer: A

Rationale: Primary hyperaldosteronism is characterized by excessive secretion of aldosterone from the adrenal cortex. Aldosterone, a hormone produced by the adrenal cortex, plays a crucial role in regulating blood pressure by promoting sodium and water retention in the kidneys. The adrenal medulla secretes catecholamines like epinephrine and norepinephrine, which are involved in the 'fight or flight' response, not in regulating blood pressure. The pancreas secretes insulin and glucagon, hormones involved in blood sugar regulation, not blood pressure. The parathyroid glands regulate calcium levels in the blood, not blood pressure.

2. An incoherent female client with a history of hypothyroidism is brought to the emergency department by the rescue squad. Physical and laboratory findings reveal hypothermia, hypoventilation, respiratory acidosis, bradycardia, hypotension, and nonpitting edema of the face and pretibial area. Knowing that these findings suggest severe hypothyroidism, Nurse Libby prepares to take emergency action to prevent the potential complication of:

• A. Thyroid storm.
• B. Cretinism.
• C. Myxedema coma.
• D. Hashimoto's thyroiditis.

Correct answer: C

Rationale: The scenario described with hypothermia, hypoventilation, respiratory acidosis, bradycardia, hypotension, and nonpitting edema of the face and pretibial area is indicative of myxedema coma, a severe and life-threatening complication of hypothyroidism. Myxedema coma requires immediate emergency treatment to prevent further deterioration. Choice A, thyroid storm, is a complication of hyperthyroidism characterized by an increase in body temperature, heart rate, and blood pressure. Choice B, cretinism, refers to untreated congenital hypothyroidism leading to mental and physical growth retardation. Choice D, Hashimoto's thyroiditis, is an autoimmune condition leading to hypothyroidism but does not present with the acute, life-threatening symptoms described in the scenario.

3. How often should rotation sites for insulin injection be separated from one another?

• A. Every third day.
• B. Every week.
• C. Every 2-3 weeks.
• D. Every 2-4 weeks.

Correct answer: C

Rationale: Insulin injection sites should be rotated every 2-3 weeks to prevent lipodystrophy and ensure proper insulin absorption. Option A ('Every third day') is too frequent and does not allow enough time for the previous site to heal properly. Option B ('Every week') might not provide adequate time for the tissue to recover. Option D ('Every 2-4 weeks') could potentially lead to overuse of a single injection site, increasing the risk of lipodystrophy and inconsistent insulin absorption. Therefore, the recommended interval of every 2-3 weeks is optimal for insulin injection site rotation.

4. The client with newly diagnosed diabetes mellitus is receiving education from the nurse on managing blood glucose levels. Which statement indicates a need for further teaching?

• A. I will monitor my blood glucose levels regularly.
• B. I can eat whatever I want as long as I take my medication.
• C. I should exercise regularly to help control my blood sugar.
• D. I will rotate my injection sites to avoid tissue damage.

Correct answer: B

Rationale: Choice B indicates a need for further teaching because it suggests that the client can eat whatever they want as long as they take their medication, which is incorrect. Clients with diabetes mellitus need to follow a healthy and balanced diet in addition to taking their medication to effectively manage blood glucose levels. Choices A, C, and D are correct statements for managing diabetes. Monitoring blood glucose levels regularly, engaging in regular exercise to help control blood sugar, and rotating injection sites to avoid tissue damage are all important aspects of diabetes management.

5. Nurse Perry is caring for a female client with type 1 diabetes mellitus who exhibits confusion, light-headedness, and aberrant behavior. The client is still conscious. The nurse should first administer:

• A. I.M. or subcutaneous glucagon.
• B. I.V. bolus of dextrose 50%.
• C. 15 to 20 g of a fast-acting carbohydrate such as orange juice.
• D. 10 U of fast-acting insulin.

Correct answer: C

Rationale: For a conscious client with hypoglycemia, the initial treatment should involve administering 15 to 20 g of a fast-acting carbohydrate, such as orange juice. This helps rapidly raise the client's blood glucose levels. Choices A and D are incorrect as administering glucagon or fast-acting insulin is not the first-line treatment for hypoglycemia in a conscious client. Choice B, an I.V. bolus of dextrose 50%, is a more invasive and aggressive intervention that is not typically indicated for a conscious client with hypoglycemia.
