Nursing Elites

1. Nurse Wayne is aware that a positive Chvostek's sign indicates:

• A. Hypocalcemia
• B. Hyponatremia
• C. Hypokalemia
• D. Hypermagnesemia

Correct answer: A

Rationale: A positive Chvostek's sign indicates hypocalcemia. This sign is elicited by tapping the facial nerve anterior to the ear, resulting in facial muscle twitching due to increased neuromuscular irritability from low calcium levels. Hyponatremia (Choice B) is characterized by low sodium levels, but it does not present with Chvostek's sign. Hypokalemia (Choice C) is low potassium levels, and hypermagnesemia (Choice D) is high magnesium levels, neither of which are associated with Chvostek's sign.

2. The client is NPO and is receiving total parenteral nutrition (TPN) via a subclavian line. Which precautions should the nurse implement? Select one that does not apply.

• A. Place the solution on an IV pump at the prescribed rate.
• B. Monitor blood glucose every twelve (12) hours.
• C. Weigh the client weekly, first thing in the morning.
• D. Change the IV tubing every three (3) days.

Correct answer: D

Rationale: Precautions for clients receiving TPN include placing the solution on an IV pump to control the rate, monitoring blood glucose levels to detect hyperglycemia, and monitoring intake and output to assess fluid balance. Changing the IV tubing every three days is not a standard precaution for clients receiving TPN via a subclavian line.

3. The nurse is caring for a client with Addison's disease. The client exhibits signs of hypotension, dehydration, and confusion. The nurse should anticipate administering which of the following medications?

• A. Insulin
• B. Hydrocortisone
• C. Levothyroxine
• D. Methimazole

Correct answer: B

Rationale: In Addison's disease, the adrenal glands do not produce enough cortisol. Hydrocortisone is a glucocorticoid medication that is used to replace deficient cortisol levels in patients with Addison's disease. It helps stabilize blood pressure and fluid balance. Insulin (Choice A) is used to manage diabetes, not Addison's disease. Levothyroxine (Choice C) is a thyroid hormone replacement used to treat hypothyroidism, not Addison's disease. Methimazole (Choice D) is used in the treatment of hyperthyroidism, not Addison's disease.

4. A client with diabetes insipidus is receiving desmopressin therapy. The nurse should monitor for which of the following potential side effects?

• A. Hyponatremia
• B. Hypernatremia
• C. Hypokalemia
• D. Hypercalcemia

Correct answer: A

Rationale: The correct answer is A: Hyponatremia. Desmopressin, a medication used to treat diabetes insipidus, can cause the retention of water without sodium, leading to dilutional hyponatremia. This occurs because desmopressin increases water reabsorption in the kidneys without affecting sodium levels. Hypernatremia (choice B) is unlikely because desmopressin does not cause excessive sodium retention. Hypokalemia (choice C) and hypercalcemia (choice D) are not typically associated with desmopressin therapy for diabetes insipidus.

5. A female client with Cushing's syndrome is admitted to the medical-surgical unit. During the admission assessment, Nurse Tyzz notes that the client is agitated, irritable, has poor memory, reports loss of appetite, and appears disheveled. These findings are consistent with which problem?

• A. Depression
• B. Neuropathy
• C. Hypoglycemia
• D. Hyperthyroidism

Correct answer: A

Rationale: The correct answer is A: Depression. Depression is a common psychological manifestation in clients with Cushing's syndrome. In this scenario, the client's symptoms of agitation, irritability, poor memory, loss of appetite, and disheveled appearance are indicative of depressive symptoms rather than neuropathy, hypoglycemia, or hyperthyroidism. Neuropathy typically presents with sensory changes and motor deficits, which are not described in the scenario. Hypoglycemia would manifest with symptoms such as diaphoresis, tremors, and confusion, which are not mentioned. Hyperthyroidism symptoms include weight loss, heat intolerance, and palpitations, which are not consistent with the client's presentation.
