Nursing Elites

1. A client with type 1 diabetes mellitus is admitted to the hospital with 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 the treatment of a client with diabetic ketoacidosis (DKA) is to start an intravenous line and infuse normal saline. This is essential for fluid resuscitation to restore intravascular volume and improve perfusion. Administering intravenous insulin can lead to further potassium depletion without first addressing dehydration and electrolyte imbalances. Monitoring serum potassium levels is important but should follow fluid resuscitation to avoid life-threatening hypokalemia. Obtaining an arterial blood gas (ABG) is necessary to assess the acid-base status but is not the initial priority when managing DKA.

2. Following a unilateral adrenalectomy, Nurse Betty would assess for hyperkalemia indicated by which of the following signs?

• A. Muscle weakness
• B. Tremors
• C. Diaphoresis
• D. Constipation

Correct answer: A

Rationale: Muscle weakness is a classic manifestation of hyperkalemia, an elevated level of potassium in the blood. After an adrenalectomy, where one adrenal gland is removed, there may be a risk of hyperkalemia due to altered hormone regulation. Tremors (Choice B) are not typically associated with hyperkalemia but may be seen in conditions like hypocalcemia. Diaphoresis (Choice C) and constipation (Choice D) are not specific indicators of hyperkalemia. Diaphoresis is excessive sweating and constipation is a common gastrointestinal issue, neither directly related to potassium imbalances.

3. A client with hypothyroidism is at risk for which of the following complications?

• A. Thyroid storm
• B. Myxedema coma
• C. Cushing's syndrome
• D. Diabetic ketoacidosis

Correct answer: B

Rationale: Myxedema coma is a severe, life-threatening complication that can occur in individuals with untreated or inadequately treated hypothyroidism. It is characterized by extreme hypothyroidism leading to decreased mental status, hypothermia, bradycardia, and respiratory depression. Thyroid storm (Choice A) is a severe complication of hyperthyroidism, not hypothyroidism. Cushing's syndrome (Choice C) results from prolonged exposure to high levels of cortisol, not related to hypothyroidism. Diabetic ketoacidosis (Choice D) is a complication of uncontrolled diabetes, not directly associated with hypothyroidism.

4. Which instruction about insulin administration should Nurse Kate give to a client?

• A. Always follow the same order when drawing up different insulins into the syringe.
• B. Shake the vials before withdrawing the insulin.
• C. Store unopened vials of insulin in the refrigerator at recommended temperatures.
• D. Discard the intermediate-acting insulin if it appears cloudy.

Correct answer: A

Rationale: The correct answer is A. Consistently following the same order when drawing up different insulins helps to prevent medication errors. Option B is incorrect because shaking insulin vials could cause bubbles to form, leading to inaccurate dosing. Option C is incorrect as insulin should be stored in the refrigerator, not the freezer, to maintain its effectiveness. Option D is incorrect because cloudy appearance in intermediate-acting insulin may indicate the presence of insulin crystals, which can affect its potency, but this does not necessarily mean it should be discarded without consulting a healthcare provider.

5. Why is glucose an important molecule in a cell?

• A. Extraction of energy
• B. Synthesis of protein
• C. Building of genetic material
• D. Formation of cell membranes

Correct answer: A

Rationale: Glucose is a crucial molecule in cells because it serves as the primary source of energy through cellular respiration. Choice B, the synthesis of protein, is incorrect because proteins are typically synthesized from amino acids, not glucose. Choice C, the building of genetic material, is incorrect because genetic material, such as DNA and RNA, is not directly built from glucose. Choice D, the formation of cell membranes, is also incorrect as cell membranes are primarily composed of lipids and proteins, not glucose.
