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. During the physical examination, Nurse Noah expects to assess which sign in a female client with a serum calcium level of 7.2 mg/dl?

• A. Trousseau's sign
• B. Homans' sign
• C. Hegar's sign
• D. Goodell's sign

Correct answer: A

Rationale: Trousseau's sign is a clinical indicator of hypocalcemia, characterized by carpal spasm when a blood pressure cuff is inflated above systolic pressure and maintained for a few minutes. This occurs due to increased neuromuscular irritability associated with low serum calcium levels. Homans' sign is used to assess for deep vein thrombosis and involves calf pain upon dorsiflexion of the foot. Hegar's sign is a softening of the lower uterine segment seen in pregnancy, while Goodell's sign is softening of the cervix also seen in pregnancy. Therefore, in this scenario, the correct assessment related to hypocalcemia would be Trousseau's sign.

3. Which of the following clinical findings would be most concerning in a client with hypothyroidism?

• A. Bradycardia
• B. Dry skin
• C. Constipation
• D. Depression

Correct answer: A

Rationale: Bradycardia in a client with hypothyroidism is the most concerning finding as it may indicate severe hypothyroidism, leading to decreased heart rate. Bradycardia can be a sign of myxedema coma, a life-threatening condition that requires immediate medical attention. Dry skin, constipation, and depression are common symptoms associated with hypothyroidism but are not as acutely concerning as bradycardia.

4. A client with DM asks a nurse why it is necessary to rotate injection sites when using an insulin pen. The nurse's best response would be:

• A. To prevent scar tissue from forming under the skin.
• B. To make the injections less painful.
• C. To help the insulin absorb better.
• D. To keep the skin looking healthy.

Correct answer: C

Rationale: The correct answer is C: "To help the insulin absorb better." Rotating injection sites is important as it helps to ensure better insulin absorption and reduces the risk of developing lipodystrophy. Option A is incorrect as rotating sites primarily aims to optimize insulin absorption, not prevent scar tissue. Option B is inaccurate because rotating injection sites does not necessarily make the injections less painful. Option D is incorrect as the primary reason for rotating injection sites is not related to the aesthetics of the skin but rather to enhance insulin absorption and prevent complications.

5. Early this morning, a female client had a subtotal thyroidectomy. During evening rounds, Nurse Tina assesses the client, who now has nausea, a temperature of 105°F (40.5°C), tachycardia, and extreme restlessness. What is the most likely cause of these signs?

• A. Diabetic ketoacidosis
• B. Thyroid crisis
• C. Hypoglycemia
• D. Tetany

Correct answer: B

Rationale: The correct answer is B: Thyroid crisis. Thyroid crisis, also known as thyroid storm, is a life-threatening condition that can occur after a thyroidectomy. Symptoms include high fever, tachycardia, extreme restlessness, and other signs of severe hyperthyroidism. Diabetic ketoacidosis (choice A) is a complication of diabetes characterized by hyperglycemia, ketosis, and acidosis, not typically seen post-thyroidectomy. Hypoglycemia (choice C) is low blood sugar levels and would not present with the symptoms described. Tetany (choice D) is a condition of involuntary muscle spasms due to low calcium levels and is not directly related to the symptoms observed in this scenario.
