Nursing Elites

1. A healthcare provider caring for a client with severe malnutrition reviews the laboratory results and notes a magnesium level of 1.0 mg/dL. Which electrocardiographic change would the healthcare provider expect to note based on the magnesium level?

• A. Prominent U waves
• B. Prolonged PR interval
• C. Depressed ST segment
• D. Widened QRS complexes

Correct answer: C

Rationale: A magnesium level of 1.0 mg/dL can cause a depressed ST segment on the ECG. Magnesium deficiency commonly leads to ST segment depression on an electrocardiogram. Prominent U waves are associated with hypokalemia, prolonged PR interval is seen in conditions like first-degree heart block, and widened QRS complexes are typically related to conditions affecting the conduction system of the heart, such as bundle branch blocks.

2. A client with a nasogastric tube requires irrigation once every shift. The client's serum electrolyte results show a potassium level of 4.5 mEq/L and a sodium level of 132 mEq/L. Based on these findings, which solution should the nurse use for nasogastric tube irrigation?

• A. Tap water
• B. Sterile water
• C. Sodium chloride
• D. Normal saline

Correct answer: C

Rationale: The correct solution for nasogastric tube irrigation in this scenario is sodium chloride. The client's low sodium level of 132 mEq/L indicates the need to avoid further imbalance, making sodium chloride the most appropriate choice. Using tap water, which lacks electrolytes, or sterile water could potentially exacerbate the electrolyte imbalance. Normal saline, while similar to sodium chloride, may not be the best choice as it contains a higher concentration of sodium, which could further elevate the client's already borderline sodium level.

3. The nurse is caring for a client with a history of adrenal insufficiency. The nurse should monitor for which of the following signs of an Addisonian crisis?

• A. Hypertension
• B. Hyperglycemia
• C. Severe hypotension
• D. Tachycardia

Correct answer: C

Rationale: In an Addisonian crisis, there is a lack of adrenal hormones leading to severe hypotension. Hypertension (choice A) is not a typical sign of Addisonian crisis but can occur in conditions like pheochromocytoma. Hyperglycemia (choice B) is not a characteristic sign of an Addisonian crisis. Tachycardia (choice D) may occur as a compensatory mechanism in response to hypotension, but severe bradycardia is more common in an Addisonian crisis.

4. The healthcare provider is assessing a client with hypothyroidism. Which of the following symptoms would the provider expect to find?

• A. Weight loss
• B. Heat intolerance
• C. Bradycardia
• D. Diarrhea

Correct answer: C

Rationale: Bradycardia is a common symptom of hypothyroidism because the condition leads to a decreased metabolic rate. Weight loss (Choice A) is more commonly associated with hyperthyroidism, where the metabolic rate is increased. Heat intolerance (Choice B) is also more indicative of hyperthyroidism due to increased sensitivity to heat. Diarrhea (Choice D) is not a typical symptom of hypothyroidism; rather, constipation is more common due to the slow-down of the digestive system.

5. A client with Addison's disease is being educated on managing the condition. Which of the following statements indicates a need for further teaching?

• A. I should carry an emergency kit with hydrocortisone at all times.
• B. I need to increase my sodium intake during hot weather.
• C. I can skip my medication if I feel well.
• D. I should avoid stress as much as possible.

Correct answer: C

Rationale: The correct answer is C. Clients with Addison's disease should not skip their medication, even if they feel well, as consistent medication is necessary to manage the condition. Choice A is correct as carrying an emergency kit with hydrocortisone is essential for managing potential adrenal crises. Choice B is correct as increasing sodium intake during hot weather helps prevent electrolyte imbalances. Choice D is correct as stress can trigger adrenal crisis in individuals with Addison's disease, so stress management is crucial.
