1. 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.

2. The client with type 2 DM is learning to manage blood glucose levels. When should the client monitor blood glucose?

A. Only when feeling unwell.
B. Only before meals.
C. Before meals and at bedtime.
D. Only after meals.

Correct answer: C

Rationale: The correct answer is to monitor blood glucose before meals and at bedtime. This timing allows the client to assess fasting levels and make informed decisions about mealtime insulin or medication doses. Monitoring only when feeling unwell (choice A) is not sufficient for proper glucose management as it may miss important trends. Monitoring only before meals (choice B) is helpful but does not provide a complete picture of the client's glucose control throughout the day. Monitoring only after meals (choice D) is less beneficial than monitoring before meals as it does not capture fasting levels. Therefore, monitoring before meals and at bedtime (choice C) is the most comprehensive approach to maintain good glucose control and prevent complications.

3. Why might an RN need professional liability insurance?

A. Protection against frivolous lawsuits without incurring expenses.
B. Immunity from being sued by the institution if guilty of malpractice.
C. Coverage for charges of libel, slander, assault, and HIPAA violations.
D. Exclusively doctors face malpractice lawsuits.

Correct answer: C

Rationale: Having professional liability insurance is crucial for Registered Nurses due to various reasons. Choice A is incorrect because there are expenses associated with defending against frivolous lawsuits. Choice B is incorrect as institutions can still sue a nurse found guilty of malpractice. Choice D is incorrect because malpractice lawsuits can be filed against healthcare professionals, including nurses. Therefore, the correct answer is C, as liability policies can provide coverage for charges involving libel, slander, assault, and breaches of patient confidentiality like HIPAA violations, offering essential protection for RNs in their practice.

4. A client with type 1 diabetes mellitus presents to the emergency department with symptoms of diabetic ketoacidosis (DKA). Which of the following interventions should the nurse implement first?

A. Administer intravenous insulin
B. Start an intravenous line and infuse normal saline
C. Monitor serum potassium levels
D. Obtain an arterial blood gas (ABG)

Correct answer: B

Rationale: The correct first intervention in a client with DKA is to start an intravenous line and infuse normal saline for fluid resuscitation. This is crucial to restore intravascular volume and improve perfusion, addressing the dehydration and electrolyte imbalances commonly seen in DKA. Administering insulin without addressing the dehydration can lead to further complications. Monitoring serum potassium levels is important but is not the first priority; potassium levels can shift with fluid resuscitation. Obtaining an arterial blood gas (ABG) is helpful in assessing acid-base status but is not the initial priority compared to fluid resuscitation.

5. A client with diabetes insipidus is being treated with desmopressin. The nurse should monitor for which of the following side effects?

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

Correct answer: A

Rationale: The correct answer is A: Hyponatremia. Desmopressin, a medication used in diabetes insipidus, can cause water retention by increasing water reabsorption in the kidneys. This excess water retention can lead to dilutional hyponatremia, where sodium levels in the body become too low. Monitoring for hyponatremia is crucial to prevent complications such as neurological symptoms. Choices B, C, and D are incorrect because desmopressin is not known to cause hypernatremia, hypokalemia, or hypercalcemia.
