Nursing Elites

1. A nurse reviews the electrolyte results of an assigned client and notes that the potassium level is 5.4 mEq/L. Which of the following would the nurse expect to note on the electrocardiogram as a result of the laboratory value?

• A. ST depression
• B. Inverted T wave
• C. Prominent U wave
• D. Tall peaked T waves

Correct answer: D

Rationale: The correct answer is 'Tall peaked T waves.' Tall peaked T waves are characteristic ECG changes associated with hyperkalemia. In hyperkalemia, the elevated potassium levels affect the myocardium, leading to changes in the ECG. ST depression (Choice A) is more commonly associated with myocardial ischemia or infarction. Inverted T wave (Choice B) is seen in conditions like myocardial ischemia or CNS events. Prominent U wave (Choice C) is typically associated with hypokalemia or certain medications. Therefore, in this scenario, the nurse would expect to note tall peaked T waves on the electrocardiogram due to the elevated potassium level.

2. Marlisa has been diagnosed with diabetes mellitus type 1. She asks Nurse Errol what this means. What is the best response by the nurse? Select the one that does not apply.

• A. Your beta cells should be able to secrete insulin, but cannot.
• B. The endocrine function of your pancreas is to secrete insulin.
• C. Without insulin, you will develop ketoacidosis (DKA).
• D. The exocrine function of your pancreas is to secrete Estrogen.

Correct answer: D

Rationale: Type 1 diabetes is characterized by the inability of the beta cells in the pancreas to secrete insulin. Choice A is correct because it highlights the role of beta cells. Choice B is accurate as the endocrine function of the pancreas includes insulin secretion. Choice C is true as without insulin, ketoacidosis can develop. Choice D is incorrect as the exocrine function of the pancreas involves secreting digestive enzymes, not estrogen.

3. You are caring for a neonate who has a cleft palate. You should inform the mother that surgical correction will be done when the infant is:

• A. 8 to 12 months of age.
• B. 20 to 24 months of age.
• C. 16 to 20 months of age.
• D. 12 to 16 months of age.

Correct answer: A

Rationale: The correct answer is A: 8 to 12 months of age. Surgical correction for a cleft palate is typically performed around this age to optimize speech development and prevent feeding difficulties. Options B, C, and D suggest later ages for surgery, which may lead to speech and feeding issues due to the delay in correction.

4. Rotating injection sites when administering insulin prevents which of the following complications?

• A. Insulin edema
• B. Insulin lipodystrophy
• C. Insulin resistance
• D. Systemic allergic reactions

Correct answer: B

Rationale: Rotating injection sites when administering insulin helps prevent insulin lipodystrophy, which is the abnormal distribution of fat at injection sites. Insulin edema (choice A) is not prevented by rotating injection sites; it is characterized by swelling at the site of insulin injection due to increased capillary permeability. Insulin resistance (choice C) is a condition where the body's cells become less responsive to insulin, and rotating injection sites does not directly prevent this. Systemic allergic reactions (choice D) are not specifically prevented by rotating injection sites; they are related to an allergic response to insulin.

5. A nurse caring for a group of clients reviews the electrolyte laboratory results and notes a sodium level of 130 mEq/L on one client's laboratory report. The nurse understands that which client is at highest risk for the development of a sodium value at this level?

• A. The client with renal failure
• B. The client who is taking diuretics
• C. The client with hyperaldosteronism
• D. The client who is taking corticosteroids

Correct answer: B

Rationale: The correct answer is B. Clients taking diuretics are at risk for hyponatremia due to excessive sodium loss. In this scenario, a sodium level of 130 mEq/L indicates hyponatremia, which is commonly associated with diuretic use. Options A, C, and D are not the highest risk factors for developing low sodium levels in this context. Renal failure, hyperaldosteronism, and corticosteroid use are not directly linked to sodium loss as seen with diuretics.
