Nursing Elites

1. The healthcare provider is assessing a client with suspected diabetes insipidus. Which of the following clinical manifestations would support this diagnosis?

• A. Polyuria and polydipsia
• B. Hypertension and bradycardia
• C. Weight gain and edema
• D. Oliguria and thirst

Correct answer: A

Rationale: Polyuria (excessive urination) and polydipsia (excessive thirst) are classic clinical manifestations of diabetes insipidus. In this condition, there is a deficiency of antidiuretic hormone, leading to the inability of the kidneys to concentrate urine effectively, resulting in increased urine output (polyuria) and consequent thirst (polydipsia). Hypertension and bradycardia (Choice B) are not typical findings in diabetes insipidus. Weight gain and edema (Choice C) are more indicative of conditions such as heart failure or nephrotic syndrome. Oliguria (decreased urine output) and thirst (Choice D) are contradictory symptoms to what is seen in diabetes insipidus.

2. 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.

3. The client has received IV solutions for three (3) days through a 20-gauge IV catheter placed in the left cephalic vein. On morning rounds, the nurse notes the IV site is tender to palpation and a red streak has formed. Which action should the nurse implement first?

• A. Start a new IV in the right hand.
• B. Discontinue the intravenous line.
• C. Complete an incident record.
• D. Place a warm washcloth over the site.

Correct answer: B

Rationale: The first action should be to discontinue the intravenous line to prevent further complications such as infection or thrombophlebitis. Starting a new IV in the right hand is not the priority as addressing the current issue is important. Completing an incident record can be done after addressing the immediate concern of the IV site. Placing a warm washcloth over the site does not address the red streak and tenderness, which may indicate an infection that requires discontinuation of the IV line.

4. The healthcare provider is monitoring a client with diabetic ketoacidosis (DKA). Which of the following laboratory findings would be expected?

• A. Decreased blood glucose levels
• B. Decreased urine ketones
• C. Increased serum bicarbonate
• D. Increased anion gap

Correct answer: D

Rationale: In diabetic ketoacidosis (DKA), there is an excess of ketone bodies produced due to the breakdown of fatty acids for energy, leading to metabolic acidosis. An increased anion gap is a characteristic laboratory finding in DKA. The increased anion gap is a result of the accumulation of ketoacids and lactic acid in the blood, contributing to metabolic acidosis. Therefore, the correct answer is an increased anion gap. Choices A, B, and C are incorrect because in DKA, blood glucose levels are typically elevated, urine ketones are increased due to the breakdown of fatty acids, and serum bicarbonate is usually decreased as it is consumed in an attempt to buffer the acidosis.

5. 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.
